Of course, Wu Hao didn't help the middle-aged man sell the erhu at a high price because he wanted to be a hero.

His target from the start was the Blood Fiend Manual.

Therefore, he deliberately put on a show to make the hoodlum think that he was deliberately lowering the price in order to take back the erhu.

Now that the show was over, the hoodlum and the middle-aged man were both satisfied.

However, he had yet to achieve his goal, so he immediately stopped the middle-aged man.

After the middle-aged man was stopped by Wu Hao, he was stunned for a moment before he immediately understood what Wu Hao meant.

"It was all thanks to little brother just now. Otherwise, my erhu would have been snatched away."

As he spoke, he seemed to have made up his mind. He took out a piece of silver and handed it to Wu Hao with a trembling hand.

Wu Hao smiled and shook his head when he saw his heart bleeding.

"Sir, you seem to have some misunderstanding about me. I'm not helping you for money."

Then, he pulled the middle-aged man to the side and casually found a sugar water stall to sit down.

" Let's be honest. Your erhu is really not worth that price. At most, it's only worth about three taels of silver."

"I helped you because I can't stand him bullying honest people."

Hearing his words, the middle-aged man hurriedly put the silver back into his pocket.

"Little brother, you have a chivalrous heart. I can't repay you." As he spoke, he searched his body for a long time before finally taking out the ancient book.

"Although this score isn't worth much, it was given to me by my teacher when he taught me. It's extremely precious to me."

"It's a pity that my aptitude is dull and I haven't learned it yet."

"I'm giving this score to you. I hope you won't mind."

Seeing the middle-aged man raise the ancient book in front of him, Wu Hao took out a silver tael from his pocket.

"I am ashamed to accept the things that Mister treasures. I bought this score. It's not much money, so you can take it as a cheap sale."

With silver in one hand and an ancient book in the other, the two of them smiled.

After a few more polite words, Wu Hao watched the middle-aged man leave the sugar water stall.

He leisurely drank a bowl of sugar water before casually putting the ancient book under his armpit and swinging it home.

"A man is innocent, but a treasure brings sin!"

Since he had been putting on an act from the beginning, he had to put on a full show.

Wu Hao wouldn't act like a pervert seeing a pampered woman as soon as he got something good.

When he got home and closed the door, Wu Hao was no longer as relaxed as before.

He carefully took out the map, lit the lamp, and studied it carefully.

On the cover of the ancient book, there were three large words written in elegant style: [Tragic Talent].

Flipping it open, he saw handwriting that looked like dog footprints. Not only did it look extremely sloppy, but the arrangement was also messy and disorderly.

Moreover, the material of this book was also very strange. It did not feel like ordinary paper, but rather like dried leather.

However, Wu Hao wasn't interested in the material at the moment. In his eyes, the words on each page of the book formed a strange picture.

After roughly flipping through it a few times, Wu Hao suddenly disassembled the ancient book and began to work like a puzzle.

After the time it takes for an incense stick to burn, Wu Haochang let out a long breath.

"Done!"

In his eyes, all the pages formed a complete bloodline diagram, and in the middle was a heart.

Gradually, in Wu Hao's eyes, the heart began to beat slowly, and the entire bloodline diagram seemed to come alive.

The black words were like black blood, flowing along his veins.

At the same time, Wu Hao's heartbeat suddenly synchronized with the heart on the chart. He even felt that his blood flow was synchronized with the chart.

This wonderful feeling did not last long. Soon, Wu Hao felt a flame rising from his heart.

The blood in his body instantly became like boiling water, spreading through his blood vessels.

An indescribable pain erupted from the inside, causing him to fall headfirst onto the ground.

The moment he fell to the ground, the Blood Essence Jade in his arms fell out and collided with Wu Hao's head.

A drop of blood flowed out and seeped into the Blood Essence Jade.

In an instant, a cool feeling flowed through Wu Hao's forehead into his body, and the burning sensation around his body also calmed down.

The feeling of going from hell to heaven in the blink of an eye made his spirit collapse. He groaned and fainted.

When Wu Hao woke up, it was already early in the morning.

Picking up the Blood Essence Jade, he muttered to himself, This cultivation technique is a little strange!

At this moment, the complete circulation diagram of the Blood Fiend Manual had been recorded. Wu Hao quickly put away the paper on the ground and stuffed it into the furnace fire.

Looking at the map turning into ashes in the furnace fire, he began to think.

To put it bluntly, this cultivation technique was to refine one's blood into a bloodthirsty aura similar to true qi.

The Blood Qi gathered in his dantian and traveled through his meridians, forming another blood circulation system.

Every time the blood circulated, it would evaporate, and the blood aura would become stronger.

Every time the Blood Qi traveled through his body, his physical body would be strengthened, and the Blood Qi stored in his Dantian would also increase.

According to the introduction of the cultivation technique, the stronger one's bloodline was, the higher the proportion of blood qi that could be converted into blood qi.

The stronger the Blood Evil Qi, the higher the percentage of the body that was strengthened after the cycle.

This cycle repeated itself. The cultivator did not need to deliberately circulate his energy, and he was constantly becoming stronger.

However, the effects of this Blood Fiend Manual's cultivation technique could be said to be heaven-defying. Relatively, it was extremely difficult to enter the rudiments.

If the blood that had suddenly evaporated could not be calmed down, the cultivator would die from the blood in his body evaporating the moment he understood the diagram.

At this moment, Wu Hao was extremely afraid. If he had not obtained the Blood Essence Jade by chance, he would have become a dried corpse by now.

However, the fear in his heart was quickly replaced by joy.

At this moment, he had completed the blood and qi refinement. In just the middle of the night, he could already feel the obvious changes in his body.

Not to mention that his hearing and sight were sharp, and he was immune to the cold and heat. The more intuitive feeling was that his body had obviously become lighter and his strength had obviously increased.

Although he did not know how different he was from a martial arts expert, Wu Hao was confident that he was much stronger than an ordinary person.

He took out a copper coin and folded it in half.

Then, he casually threw the copper coin into the brick.

"I can be considered an expert now, right? At the very least, he's better than that gambler!"

Thinking of this, Wu Hao found a sachet and put the Blood Essence Jade in it. Then, he carried the sachet with him.

Then, he looked at the ashes on the ground and fell into deep thought.

There was indeed something wrong with this world. Not only were there strange things like ghouls, but even the cultivation techniques they practiced did not seem to be traditional martial arts.

However, Wu Hao couldn't care less now. To survive in such a world, it was naturally better to be stronger.

As for whether it was martial arts or mantras that increased his strength, what difference did it make?

Thinking of this, Wu Hao felt relieved.

With the cultivation technique of refining blood and transforming qi, he finally had the means to protect himself and the capital to develop.

All that was left was to do his job well and get a few top-grade props when he had the chance to raise his strength to the next level.

Wu Hao couldn't help but smile when he thought about how he would be able to travel back in time.
