Second Immortal Gu

...

"Little friend, you are Thieving Heaven Demon Venerable's inheritor. You have three opportunities to ask me to refine Gu. However, whether it succeeds or fails, refining an Immortal Gu will count as one chance. If you request mortal Gu, I can guarantee success and will refine it for you without fail," the land spirit proposed earnestly. "I suggest you start with mortal Gu so you don't waste your three chances."

Fang Yuan smiled calmly. "I've already made up my mind. I want to refine an Immortal Gu."

The Lang Ya Land Spirit looked disappointed but responded, "Alright, which Immortal Gu do you want to refine?"

"Second Aperture Gu," Fang Yuan declared.

Second Aperture Gu was a Heaven Path gu which allowed gu masters to cultivate two apertures at the same time.

Hearing this, the land spirit smiled. "I don't have the main refinement material for that Gu. And do you even have the recipe?"

Fang Yuan's expression turned slightly anxious. "I do have the recipe for this Immortal Gu, but the agreement states that the materials are your responsibility, correct?"

The land spirit's smile widened. "Yes, you're right. I'll search for Divine Travel Gu in Treasure Yellow Heaven until I can purchase it. But you know how hard it is to acquire an Immortal Gu," he said, offering another suggestion. "How about refining a mortal Gu for now?"

Fang Yuan suddenly grinned. "Oh, how convenient. I know exactly where the Divine Travel Gu is. Hahaha!"

The land spirit's face froze in shock. "W-What? You know where it is?"

Fang Yuan nodded. "Yes, just give me a few days. I need to prepare and go exchange for it. But remember, Land Spirit, the cost of the material is on you, right?"

The land spirit was stunned by how fast things were moving. "Y-Yes, that was part of the agreement."

Fang Yuan's grin grew even wider. "Then please arrange a room for me. I'll be staying here for a few days to prepare a few things."

Still in shock, the land spirit sent Fang Yuan to a room, but his mind remained numb from the unexpected turn of events.

After some time, the Lang Ya Land Spirit realized he had been tricked and became furious. "He has the recipe, so he must have known the main material from the start. As expected from a Demon Venerable's inheritor!"

...

At the room provided by the Lang Ya Land Spirit, Fang Yuan sat calmly, organizing his thoughts and refining his plans with the help of the A.I. Chip.

"Everything went smoothly," Fang Yuan thought, his expression calm. "From the killer move to dealing with the land spirit."

He paused for a moment, a glint of calculation in his eyes. "my big plan is progressing well. Now, it's time for the next step: refining some Gu."

Without delay, Fang Yuan took out his materials and the various Gu worms he had prepared. With the huge knowledge already stored in his mind and the assistance of the A.I. Chip, he began refining immediately.

Meanwhile, Lang Ya Land Spirit couldn't help but spy on Fang Yuan, observing the process closely. As the land spirit watched, his eyes widened in disbelief.

"How can he be this good? This... this is a mortal? He's refining these Gu so easily!"

The land spirit's shock deepened with each passing moment. "He even stops just before something goes wrong, as if he can foresee the future! Is this... is this how a mere mortal can refine Gu?"

What Lang Ya Land Spirit didn't realize was that Fang Yuan's ability to avoid mistakes came from the A.I. Chip's continuous simulations and analysis. The simulations allowed Fang Yuan to navigate the refinement process with almost unnatural precision, making it seem as if he could indeed predict the future.

Five days passed.

Fang Yuan had already refined a large number of Gu from various paths—sword path, thunder path, fire path, and even dark path. Throughout this time, the land spirit continued watching, utterly shocked at how smooth Fang Yuan's refinements were.

"This level of accuracy... not a single accident... how is this possible? Even I can't achieve this level of control!" the land spirit muttered to himself. "And it's not luck either... it's him. It's Fang Yuan!"

After another four days, Fang Yuan finished his refinements. He looked at the newly refined Gu in front of him with satisfaction.

"I've prepared enough now. Time to get some rest and then go meet with Lang Ya Land Spirit."

With that, Fang Yuan calmly packed away his materials, his mind already calculating his next move.

...

The next day, Fang Yuan approached Lang Ya Land Spirit with a calm expression. "I'm ready, Land Spirit."

"Oh, little friend, you're going to retrieve the Immortal Gu already?" Lang Ya Land Spirit's tone was unusually friendly.

This was precisely why Fang Yuan had chosen to refine Gu under Lang Ya Land Spirit's watchful eyes. His goal wasn't just to demonstrate his exceptional ability in refining but, more importantly, his mastery of wisdom path, which gave the illusion that he could predict the future and make flawless calculations. This subtle display of power was aimed at earning the land spirit's trust, especially when it came to the semi-immortal recipes in his possession.

Of course, the wealth Fang Yuan would gain from this was substantial. But his true objective was securing a specific semi-immortal recipe that would play a critical role in his larger plan.

"No need to go anywhere," Fang Yuan said, shaking his head lightly. "We can begin the refinement right here."

Lang Ya Land Spirit looked confused, about to speak, when Fang Yuan retrieved a Rank 5 Gu from his aperture—Moving Perspective Cup Gu.

Moving Perspective Cup Gu was a unique storage-type Gu. It allowed for the storage and transportation of "things" across the Space Cave, using its body to swap items between itself and its counterpart. Distance didn't matter between the two cups. By harnessing the mystical forbidden passage of the Space Cave, it bypassed the Regional Walls of the five regions, making it incredibly valuable for Fang Yuan's purposes.

With a simple command, Fang Yuan activated the Gu and sent out a Letter Gu. Moments later, the Divine Travel Immortal Gu, along with another Letter Gu, was transmitted back to him.

Fang Yuan opened the letter, reading the report from Little Hu about how she missed him in the 34 hours since his absence. Smiling slightly, he remembered the difference in time flow—Lang Ya Blessed Land flowed 36 times faster than normal, while Hu Blessed Land had a time flow five times faster than normal.

To Fang Yuan, the 10 days he had spent refining Gu here had only translated to more than 6 hours outside and a little over 34 hours in Hu Blessed Land.

Satisfied that everything was in order with Hu Blessed Land, Fang Yuan turned to Lang Ya Land Spirit and said, "We can begin refining Second Aperture Gu now, right?"

The land spirit, still somewhat bewildered by how quickly everything was progressing, nodded. "Ah, yes."

Fang Yuan's smile grew wider. "Then let's begin."
