Sudden Inspiration

The secret tunnel was brief; after walking for a while, Fang Yuan arrived at a huge hall.

The pure white hall was made of bones. In the centre was a huge tank.

The vat was filled with milk like a white liquid that smelled fragrant.

When Fang Yuan approached him, he activated his system to scan all the Gu and the milk fountain inside. There were so many in there that he managed to scan enough for it to be in the system for free.

[Scan Rank 1 – Bone Spear Gu – for 200 points?]

[Scan Rank 1 – Bone Spear Gu – for 100 points?]

...

[Scan Rank 2 – Spiral Bone Spear Gu – for 600 points?]

[Scan Rank 2 – Spiral Bone Spear Gu – for 300 points?]

...

[You have scanned enough Rank 1 Bone Spear Gu, now you can acquire them for free in the system]

[You've scanned Rank 2 Spiral Bone Spear Gu enough; now you can acquire them for free in the system]

[You've scanned enough Source of Milk, now you can get them for free in the system]

Fang Yuan picked up a Bone Spear from the system to assess it - This Gu was as big as a human finger and was completely white. One end was round, while the other was sharp, like a miniature spear.

Then he took a Spiral Bone Spear from the system and noticed that this Gu was similar to the Bone Spear Gu, but on the surface of the bone spear, there were spiral marks, probably giving more penetration damage.

Fang Yuan left the hall and entered another secret tunnel, arriving at the second white hall.

In the centre of the hall were three pillars of white bone.

A human hand was carved at the end of the pillar, without skin or flesh, only bones.

In the white bone hand, each of them held a Gu.

Three pillars, three sleeping Gu worms.

Fang Yuan walked over and saw what was carved on the pillars, explaining the characteristics of the three Gu.

"Gu rib cage shield, Gu flying bone shield, Gu arm bone wings…." Fang Yuan looked at the pillar, reading the contents.

Very quickly, his gaze focused on one line – "Three, choose one, satisfied at heart. Inheritance from Bai Gu left to future descendants."

The Gu ribcage shield could make a Gu Master grow two rows of ribcages, protecting his chest, and had a great defence. It was a Rank 3 Gu, the advantages being: In addition to the initial growth period, which needs a lot of primal essences, afterwards it can be sustained without primal essence, something like the heavenly essence treasure lotus, after being refined, can be used without injecting primitive essence.

Gu flying bone shield, after use, three flying bone shields would fly, being small and floating around the Gu Master.

Gu arm bone wings would grow a pair of bone wings in the forearm area; flapping the wings would slightly increase movement speed, most importantly, attack speed.

If it were other people, they would only have to choose one; this is a fair faction inheritance; this area tested the heir's self-control; if they couldn't control their greed and desires, taking all three Gu, then the future tunnels would drastically change, but Fang Yuan could use his system to scan all three Gu worms and still be eligible to receive the rest of the inheritance.

Fang Yuan scanned the three Gu worms and then chose one at random to be able to move forward on the inheritance.

Fang Yuan then moved towards the length of the secret tunnel and entered a third corridor.

There were no more tunnels now beyond the corridor, just a human skeleton in the cave in a sitting position.

Before the human skeleton, there was a huge book.

This book is made of bones, an arm's length, half an arm's width, and eight inches thick.

Fang Yuan picked up the book and started leafing through it - This book had the title "Grey Bone Huge Book" written on it. Inside, there were many refinement recipes, as well as the creator's inheritance, the life experiences of Gray Bone Scholar and why he put together this inheritance.

At the end of the book, it says: This corpse is the Gray Bone Scholar himself. If the future heir is so kind, they may also pay homage to him and prostrate himself three times. Then they can split the skull and get a Gu. This is the Gray Bone Scholar's lifetime Gu; if the heir obtains it, they must make the World a better place and uphold justice.

After Fang Yuan finished reading the book, he sold it to the system, and without hesitation, he prostrated three times before the corpse. He banged his head hard on the ground with each prostration; when he finished, his head was bleeding profusely, and a huge wound had formed at the spot.

Fang Yuan didn't worry much about this small wound and healed it immediately with his Healing Gu.

There are no more secret tunnels in this corridor, but it's not the end. This place tests the nature of the heir; if the person is kind and knows gratitude, he would prostrate himself. What Fang Yuan thought made no sense; what makes one think that hitting one's head on the ground three times shows kindness and gratitude?

But Fang Yuan put those thoughts aside and started waiting for the next path to open up. After a while, a section of the bone wall shrank away, revealing a new tunnel.

Seeing this, Fang Yuan smiled but continued waiting for the next door to open. After waiting for five minutes, suddenly, a new door opened, revealing another tunnel.

Fang Yuan laughed out loud, lunging forward and lifting his leg, smashing Gray Bone Scholar's corpse to pieces.

When this tunnel appeared, the corpse lost its meaning.

Fang Yuan removed a Gu, a Rank 3 Bone Spike Gu, from the skull. This Gu was the size of a fist and was like a ball cactus, with spines-like bone and spikes all over its surface. It was also heavy.

A Rank 3 Gu is a typical Gu that damages the enemy and the user; if the enemy received one thousand damage, the user would receive eight hundred damage.

When a Gu Master used it, his skeleton would change before hard and sharp bone spikes protruded.

Before even using these bone spikes to face the enemy, these bone spikes would first pierce Gu Master's flesh and skin. The pain was still secondary; if no corresponding healing Gu matched it, the situation would be really messed up.

The enemy might not die, but it would seriously injure the Gu Master who used it.

Fang Yuan scanned this Gu and then headed towards the next tunnel. A flight of descending stairs spread out inside the door. This flight of stairs was long, at least a thousand meters.

The surrounding lights gradually dimmed as they reached the last half of the stairs, and the stairs were also getting narrower.

By the time Fang Yuan reached the bottom of the stairs, the light had almost completely disappeared. In front of him was a tightly closed door.

There were four words carved into the door - Flesh Sac Secret Chamber.

Fang Yuan admired the door for a while before using his strength to push it open. The door was not locked and opened easily.

Behind the door was a hidden room that wasn't that big but very grotesque.

The walls of the hidden room were all made of meat. When Fang Yuan entered, he felt like he had entered some monster's stomach.

The walls of flesh were warm and lightly pulsing rhythmically as if a heart was inside them.

As if sensing someone's presence, the walls of flesh suddenly cracked open and revealed white teeth everywhere.

There seemed to be countless large gaping mouths in the walls of flesh.

The mouths opened with clenched jaws, revealing a set of matching teeth. The phrase 'baring fangs' fit this scene perfectly.

Heeheehee… hahaha… hehehe…

These mouths let out all kinds of laughing sounds. Laughter mingled and echoed in this narrow secret chamber; anyone listening would feel their hearts flutter!

Fang Yuan looked around and started preparing to scan all the Gu worms that were hidden here: "Hehehe, even if I spend a whole week here, I will go get all the Gu that are stored here."

He had just said this when suddenly teeth completely fell out of an open mouth, and a scarlet tongue stuck out from the mouth.

The tongue was very long, about a meter, and the front part was curled.

When the tongue fully extended, the tip of the tongue began to straighten and revealed a book on it.

This was also a book of bones, except it was many times smaller than the Huge Book of Gray Bones, Pocket-sized, about half the size of an adult's palm.

Fang Yuan picked it up and started looking through it.

The main idea behind the book's content was: since the successor can reach this place, it is proof of your pure nature, and now you can inherit my true heritage. I have two identities; 'Grey Bone Scholar' and 'Flesh Bone Master'. This Flesh Sac's secret chamber contains many Gu; if the successor is predestined, you can try to knock your teeth; if your luck is good and you open your teeth, you can take the hibernating Gu worm inside.

Fang Yuan bent his index finger and lightly tapped his teeth. These teeth were like instruments and produced some clear musical tone when struck.

She had just knocked randomly, and this mouth suddenly stopped laughing; her teeth completely fell out, and a long scarlet tongue stuck out, revealing a Gu inside it.

"It's the famous Rank 3 Healing Gu - Flesh-bone Gu!" After looking at this Gu, a pleasant surprise appeared on Fang Yuan's face; who knew that he would be lucky enough to get one of the most valuable Gu here on the first try?

This Gu looked quite peculiar as it looked like a set of dentures, immaculate white teeth with an exceptionally clean set of upper and lower teeth, and they gave off a pearly sheen. Fang Yuan scanned it and continued his harvest.

Fang Yuan had spent hours opening all the Laughing Meat Gu, he had gained a lot of interesting Gu in this harvest, and the entrance to the next secret tunnel had been opened long ago.

After he opened the last Gu, he scanned it just like he did all the others before heading to the secret tunnel.

Fang Yuan came to a hallway as they walked through this secret tunnel. He was arriving in a huge hall. This was the widest hall of bones he had encountered so far.

Only in the area were there more than 2 km². In the centre of the hall was a pyramid of bone; the peak was flattened into a platform with two flights of stairs leading to it.

Fang Yuan climbed this, freaking out, reaching the platform. There was a carving of the skull of a giant ferocious beast on the platform; he was taller than half a man and looked like a lion or a tiger, with his fangs tightly clenched.

Fang Yuan took a closer look at this sculpture and saw it had written just below it – "Twins with one mind, three spirits unite. Predestined or not, don't be strong..."

Operating this gadget takes two people, but Fang Yuan came to explore this heritage alone and badly needed the Gu that this gadget would refine.

But Fang Yuan didn't despair; he was prepared for this and had a plan before coming here. A little over five months ago, the group chat members arrived on a mission and as soon as they arrived, the group chat system updated the shop to sell items from the members' worlds and the ones they've already visited. And they also invited a new member to the group on this trip.

But that's not Fang Yuan's trump card; Fang Yuan's true plan was to use the quest request function for any party member to call someone to help him refine those Gu, and who better than his best friend and brother: John Lockhart?

[Fang Yuan: John, my old man, the time has come. I have already reached the end of the Bai Gu mountain heritage, and I need your help to refine the Bone Gu Meat Unit]

[John Lockhart: Okay! I am going]

A short time later, a figure of a tall man with dark skin appeared beside Fang Yuan out of nowhere. That figure was John Lockhart, who regained his true body as a gift from the system by accepting to be transported to another world.

"It is good to see you again, my good friend." John hugged Fang Yuan as he let out a few manly tears.

"Me too!" Fang Yuan immediately returned the same hug with his friend.

After catching up and spending some time together, they finally decided to address the problem in front of them.

"Come, place your palm on the sculpture's pupils."

There was a pure, translucent red gem in the eyes of the skull carving. The red stone was as big as large china bowls and reflected the figures of Fang Yuan and John Lockhart.

Fang Yuan and John Lockhart have been friends for a long time and trust each other with their lives; normally, if two random people tried to activate this mechanism, it would not activate, but Fang Yuan and John had a great history of trusting each other, so they can think as one mind when they need to. For this reason, Fang Yuan chose John over anyone else; he was sure that with John's help, he would achieve rank 5 - Flesh Bone Gu Unit.

The moment the two touched the red gem, it let out a bright light.

Crack, Crack…

The skull slowly opened its mouth and revealed a large pile of charcoal stones and dry wood.

In the centre of the black charcoal stones was a plain-looking ceramic vessel, and a scroll was on top of it.

Fang Yuan casually crouched down, picked up and read the scroll that explained the Gray Bone Scholar's life.

The owner of this inheritance, Gray Bone Scholar, did not have great aptitude; thus, he was distressed about his cultivation throughout his life.

He had put all his efforts into researching a type of Gu that could help a Gu Master cultivate quickly.

There was already enough cultivation assisting the Gu worms; the most typical is the liquor worm. However, these Gu worms were very rare and would be very difficult to popularize.

Gray Bone Scholar's aspiration was great; he wanted to research and refine an excellent Gu worm that could be widely used.

However, even after numerous failures, he failed to achieve success even when his lifespan was coming to an end.

At the final juncture of his life, perhaps heaven took pity on him; when establishing the bone-white mountain inheritance, he suddenly had an extremely ingenious enlightenment.

What was the main method to quickly increase a Gu master's cultivation without the help of specific Gu worms?

It was to allow an elder to impart his primal essence.

Previously at Qing Mao Mountain, Gu Yue Chi Cheng had received such help, receiving the refined primal essence of his grandfather Gu Yue Chi Lian.

However, this move had a major drawback.

It was the mixture of different primal essences, relying on an elder's primordial essence to wash and refine the aperture walls, leaving behind his aura in the aperture, making the future development of a Gu Master very restricted.

Unless someone uses Gu cleansing water to clean the mixed aura.

However, the Gu cleansing water was also rare, and ordinary Gu Masters would find it difficult to obtain it. Even older-level characters would have to rely on luck or pay a tremendous price.

So transmitting method also could not be broadcast.

Consequently, Gray Bone Scholar thought of a wonderful concept.

If there was a Gu that could refine another's primal essence into the Gu Master's primal essence, wouldn't that mean that there would be no mixed aura after transmission?

He started making a series of attempts, and after eliminating most of the possibilities, he devised a plan with the highest probability of success.

The name of that experiment was - "Bone Flesh Unity Gu".

This was written on the scroll: To refine this Gu, two Gu Masters must work together. And these two Gu Masters must be blood-related; Parents and children or twins. Relying on the bloodline connection, one can transform the primal essence.

However, Gray Bone Scholar needed more time to implement this concept. After having done most of the preparations, he could only helplessly stop at the final moment.

Although he had two nicknames, he was nevertheless just one person. What was missing were two Gu Masters that met the criteria.

The scroll's final contents revealed Gray Bone Scholar's unending regret.

He didn't have enough time to redo the preparations and could only put this project behind him. If someone predestined reached this point and could open the mechanism and see this scroll, it would mean that the Gu Masters who met the conditions had appeared!

"There is no harm in trying, no matter what the result; please take it to my tombstone." Those words on the parchment contained a lifetime of Gray Bone Scholar obsession.

After reading the entire history of the creator of this heritage, Fang Yuan opened the Chat system store and purchased Gu Rank 5 – Shared Bloodline and Gu Rank 5 – Fake Primitive Essence. Unlike his system store, which only sells the items he has scanned, the Chat system store sells all items in his World.

The Shared Bloodline Gu looked like any other pebble found on the road; the only difference was that it glowed a deep crimson.

The Primitive Essence False Gu looked like a transparent ball, similar to a Gu Master's aperture.

Fang Yuan naturally needed more points to buy items from the Chat system shop, but John had recently completed a system quest and was full of points, so he just borrowed some and bought the Gu.

Fang Yuan pricked his finger, let a drop of his blood drip onto the Shared Bloodline Gu, and then used it on John Lockhart. This Gu has the function of giving someone a lineage temporarily; now John has the same lineage as Fang Yuan, turning the two into practically Twins.

The Primal Essence False Gu could allow a mortal to use Primal Essence for a while; the Gu would devour Primal Stones to Generate Primal Essence, making it possible for a mortal to use it.

"Come, help." After handing over the Fake Primal Essence and using Shared Bloodline on John, Fang Yuan had John light the dry wood on the skull carving while he injected primal essence into the red gem.

The fire instantly rose and burned furiously. The blazing fire suddenly changed colour from orange to eerie blue.

The pottery vessel was roasted by fire; the various hibernating Gu worms woke up from the heat and started fighting maniacally. The ceramic container was constantly rocking, but it was not damaged.

The refining steps were simple; John stood and assisted as Fang Yuan poured out his primaeval essence.

Soon, they arrived at the final critical moment.

This step needed fresh meat from the two Gu Masters, which would be thrown into the fire to be purified. The parchment clearly stated that the more meat was thrown into the fire, the better the effects.

Without hesitation, the two cut off their arms and threw them into the blazing fire. Fang Yuan acted quickly and regenerated the two's arms immediately.

When his flesh landed on fire, the previously mysterious blue fire immediately changed and became reddish-purple.

Fang Yuan and John poured their primordial essence into the red gem pupils simultaneously; the mechanism slowly began to close like a bone beast engulfing burning flames.

Two rows of fangs came together, and the jaws closed securely; the flame continued to burn from within, burning the skull in a scarlet hue.

Bang! The ceramic container appeared to have exploded.

The entire skull shook.

Fang Yuan and John let go of their hands only after hearing that sound.

The skull slowly opened in the blink of an eye; the fire had already disappeared.

There were no traces of the ceramic vessel or Fang Yuan and John's arms.

Two Gu worms appeared in Fang Yuan's sight.

One was green and the other red; they were strung together like two jade bracelets and silently exuded a warm glow as they hovered in the air. Without hesitation, Fang Yuan picked them up and scanned them with the system.

"It worked out?" John, who was on the side, asked to confirm.

"Yes," Fang Yuan smiled as he looked at the Flesh and Bone Gu Unit with satisfaction. He will finally be able to study this very special Gu worm.

"If it's already worked out, I'll say goodbye then; I have much to do in my world, too," John said goodbye to Fang Yuan and left his World.

After saying goodbye to his friend Fang Yuan, he started to study this Gu; luckily, he got the highest quality possible - Blood Kin Relation Gu.

After a week of studying this, Gu Fang Yuan had a sudden inspiration for a new Dream Path, Gu Worm. He then drowned in that inspiration as he tried to devise a reasonable recipe for this new Gu Worm of the Path of Dreams.
