One person: I, Daoist Master, am a cultivator of immortality!

"Hmm, your idea is indeed quite ingenious. Even I couldn't have come up with this trick, but with your experience, it's actually quite simple."

As Chu Feng spoke, he did the same as Sun Yao, and a thick pillar of lava rose up in front of them again, more than twice as thick as the one Sun Yao had just used.

"Master is indeed worthy of being called Master. I'm not even proficient in using this move yet, but Master is already far superior to me just by hearing the principle."

"Don't underestimate yourself. It's true that it's much simpler for later learners than for the creators. But if there were no creators, where would the later learners come from? Although later learners know the principles, the creators also know the flaws, don't they? I don't believe there's no way to counter this kind of move."

"Of course there are, but who could use that trick on me? My master certainly wouldn't do that to me."

"You slippery fellow, you can never be too careful. Don't give this Heavenly Divine Fire Pillar to anyone other than me. Not even that kid Fengping, he loves to show off too much. If someone else figures out this trick, it will be a disaster for you."

"Yes, I understand, Master. Why don't we go and see what this person is hiding in his house? I think even in a life-or-death situation, he's thinking of running into the house. Maybe there's something important to him inside."

"Yes, that's right. I think that old guy ran back quite fast just now, there must be something in this house that he can't let go of. At this critical moment of life and death, what he can't let go of must be related to his life and fortune."

Chu Feng also thought his disciple's speculation was quite accurate. He believed he could kill him with ease, and since the man was still trying to run into the house even under his attack, there must be something in the house that he couldn't abandon.

Chu Feng and Sun Yao entered the room together. Contrary to their expectations, the room was surprisingly clean and tidy. There wasn't much in the room; the only truly important item was the Gu-refining manual on the table.

This thing looks quite old; it was recorded on bamboo slips. It appears to have been unearthed and passed through many hands before finally reaching his possession.

"The Record of Gu Refining is said to be a notebook left behind by a legendary Gu master from the Miao region during the Han Dynasty. It suddenly appeared in the world in the last few hundred years, probably unearthed by some tomb raider. It is said that this legendary Gu master once fought with the immortal Zuo Ci, and the two were evenly matched. Although that's what they say, it's all unofficial history. I don't know if this so-called Record of Gu Refining can be considered a rare book, but I've never heard of any Gu master ever possessing it."

"So, this book is very likely to be overrated? No matter how famous it is, no great Gu master has become famous because of it."

"You can't say that; we have to take a look first."

As Chu Feng spoke, he placed the Gu Refining Manual in Sun Yao's hands. Sun Yao said nothing and casually flipped through the manual. It contained no cultivation instructions, only various Gu worm recipes. It turned out that the Gu Refining Manual didn't record any cultivation methods; it was simply a notebook for refining Gu worms.

If someone were to refine Gu worms according to the records here, they could certainly succeed. However, the moment the Gu worms are born, they will turn against their master. Without cultivation, it's impossible to control the Gu worms. Refining Gu worms before cultivating internal energy is a path to death. No wonder no one has ever become a Great Gu Master after obtaining this record of Gu refining.

This record of Gu cultivation is an added bonus for those with extraordinary abilities, a help that would be like adding wings to a tiger. But for those who have not cultivated, it is a bottle of poison that constantly attracts people to make mistakes.

Of course, it would be a lie to say that any renowned Gu masters haven't experienced this Gu Refining Record. Many well-known Gu species are actually recorded in it. For example, the Living Gu King Snake, one of Chen Duo's main Gu worms, is listed in the simple Gu worm section of the Gu Refining Record.

The simple Gu worm recorded in this Gu Refining Record is one of the main ancient Gu worms of the Gu Body Saint Child, which gives you an idea of ​​what this Gu Refining Record is all about. Most importantly, Sun Yao found an introduction to the Gu Body Saint Child in this Gu Refining Record.

The Record of Gu Refining also records the Gu Body Saint Child as a type of Gu on this bamboo slip, which resembles an experimental notebook. Moreover, the record only states that refining the Gu Body Saint Child is quite difficult, not even the most difficult level in the Record of Gu Refining. One can imagine what kind of existence this Record of Gu Refining is. But this makes Sun Yao even more puzzled. How could the Medicine Immortal Society allow such an important book, especially such a crucial original, to be brought out by someone like this?

Sun Yao was puzzled and couldn't help but look at his master. Chu Feng naturally knew that his disciple would have questions, "Just ask whatever you want to ask, don't look like you want to say something but hold back."

“Master, I felt that person wasn’t particularly strong just now. But this Record of Gu Refining is ridiculously strong, or rather, it’s terrifyingly powerful. The various Gu worms described in it are incredibly difficult to refine, some even requiring human sacrifice. How could the Medicine Immortal Society allow such a person to bring out the original Record of Gu Refining?”

"You don't understand this. It's precisely because this 'Treatise on Gu Refining' is the original that it was possible for him to bring it out. The rubbings of this 'Treatise on Gu Refining' should be strictly controlled by the Medicine Immortal Society, which is why the original is kept in a high-end place. This gave this person the opportunity to bring the original out. Presumably, this person is a defector from the Medicine Immortal Society, and he's doing this to fool these ordinary people into kidnapping children for Gu refining. He even wants to use those high-end Gu worms to prevent the Medicine Immortal Society from pursuing him."

"Hmm, very likely. But now that this thing has fallen into my hands, could I refine some Gu worms as a means to achieve this?"

"Of course, our Huode Sect doesn't mind its disciples learning other methods. If you can enhance your strength through this record of Gu refining, I would be more than happy to oblige. However, there is something I must tell you beforehand: Gu refining is allowed, but it must not be immoral or harmful. You cannot disregard the lives of innocent people for the sake of so-called powerful Gu worms. I believe you can do this, right?"

"Don't worry, Master. I'm not a heartless, lawless madman. I still value basic human ethics and morality. Using human materials has crossed my bottom line. This kind of thing can't happen to me, so you can rest assured."
