Two days later, Gu Yao joyfully looked at the liquid in the porcelain bottle. Silver sparkles shimmered within, giving it a splendid and mysterious appearance. It differed from the potential elixir he had made in his previous life, but relying on years of alchemy experience, he was sure this potion was a great success.
Xu Chen's eyes showed a hint of surprise. He had watched from start to finish, and Gu Yao didn't hide anything from him. He didn't expect that alchemy could be done like this.
The dual-attribute Nascent Pill took Gu Yao quite some time. However, what he finally extracted was different from what he had expected. It wasn't simply using the essence of the Nascent Pill but an inexplicable substance. After repeated refinement, he had a feeling that it was the most fundamental essence within the Nascent Pill, not easily extractable through ordinary alchemical methods.
"What effects does this potion have? What's its name?" Xu Chen asked curiously.
Gu Yao tilted his head and thought, "It's an improvement based on the potential elixir. It's used to stimulate and enhance a person's innate talent."
Xu Chen's eyes turned on Gu Yao, surprised by the potion's effects. Was this the potion Gu Yao used on himself?
Gu Yao didn't guard against him, so Xu Chen could perceive it. Gu Yao's main spiritual root was Wood-Fire, among the mixed spiritual roots. "Do you want to enhance your spiritual roots? In the cultivation world, there's a pill called the Cleansing Spirit Pill that can remove excess spiritual roots. However, even with the recipe, it's useless because the main spiritual herbs have long been extinct."
Gu Yao's eyes lit up for a moment, then he calmed down. He shook his head and said, "I can study the Cleansing Spirit Pill later when I have the ability. As you know, spiritual roots vary in thickness. The thicker, the stronger the roots, and the higher the talent for cultivation. My Wood-Fire main spiritual root isn't much thicker than the remaining secondary spiritual roots. So, I'm thinking of increasing the strength and purity of my main spiritual root."
Xu Chen praised, "Quite imaginative. But are you sure it will succeed?"
How old is this kid? Daring to do what alchemists usually do?
A hint of madness flashed in Gu Yao's eyes. "Whether it succeeds or not, trying it will tell."
He poured the potion from the porcelain bottle into his mouth, downing it in one go. Xu Chen couldn't stop him in time, watching in astonishment.
Xu Chen didn't know if Gu Yao's madness was to improve his aptitude or simply to verify the potion's effects. Regardless, both seemed somewhat frightening.
Crazy little guy!
Suddenly, Gu Yao groaned, fell to the ground, gritting his teeth. Xu Chen quickly moved him to an open space. Saying he wasn't worried about Gu Yao's situation would be a lie. If Gu Yao played himself to death, who knows whose hands this treasure would fall into, and whether the next cultivator's morality would be as simple as Gu Yao's?
Using his spiritual sense to observe Gu Yao's internal situation, Xu Chen saw the silver liquid he drank running rampant through his body. It continuously infiltrated his muscles, blood, and even bones. The liquid's components were highly aggressive, constantly tearing apart the original cells. This was the main reason Gu Yao found it difficult to endure. However, there was another component in the potion that alleviated this tearing sensation.
On the surface, blood vessels bulged under the skin, and small fleshy masses protruded from the muscles. The pain was extreme, and Gu Yao screamed on the ground, with blood vessels occasionally bursting, blood flowing out. Fortunately, Xu Chen noticed that Gu Yao's consciousness remained very clear, relying on his own willpower to try to overcome this challenge.
After observing for a while, Xu Chen muttered, "Is he really remodeling his own body and constitution?"
Then, his eyes lit up. If this potion was truly successful, placed in the cultivation world, it would cause a great sensation. Even high-level cultivators would be greatly tempted. It wasn't just useful for low-level cultivators.
Of course, with his experience, Xu Chen could see that the potion Gu Yao currently refined was only useful for a Qi Refining cultivator like him or someone who hadn't cultivated yet. As cultivation level increased, it became challenging for the potion to break the balance within a cultivator's body for remodeling. However, if Gu Yao could refine such a potion, he might be able to create higher-level transformative elixirs based on this foundation.
He couldn't help but pay more attention to Gu Yao. If Gu Yao had such ability, continuing to improve his aptitude might lead to a longer and more successful cultivation path. This was also beneficial for Xu Chen. "Kid, you better be determined and not give up halfway."
Gu Yao opened one eye, glanced weakly at Xu Chen, then closed it again, resisting the intense pain in his body.
Watching Gu Yao turn into a bloody figure and then seeing his breath gradually calm down as the transformation within his body ended completely, he lay on the ground, breathing heavily. Despite looking disheveled, Gu Yao revealed a relaxed smile.
Xu Chen immediately grabbed Gu Yao's wrist, saying, "Let me check the condition of your spiritual roots."
Xu Chen soon made a soft exclamation because he found that Gu Yao's spiritual roots had indeed changed after taking the potion. The Wood-Fire spiritual root had significantly strengthened. He didn't expect this kid to succeed: "Kid, does this medicine only work the first time, or can it be taken continuously?"
Gu Yao, lying weakly on the ground, answered, "It's only effective the first time, but this potion can be upgraded. This time, I used the inner core of a first-level high-rank demonic beast. Maybe I don't have to wait until the Foundation Establishment stage to try the inner core of a second-level demonic beast. However, the prescription needs improvement. After all, as cultivation advances, the body becomes harder to transform."
Xu Chen took a cold breath. If what Gu Yao said was true, progressively transforming like this, what kind of monster would he become in the end?
"Kid, aren't you afraid I might harm you? Revealing such a big secret to me?" Xu Chen asked curiously. Shouldn't he keep something hidden from him?
Gu Yao raised an eyebrow, "Senior has even lost his physical body. This potion won't have any effect on Senior."
Xu Chen felt like vomiting blood. This brat specifically hit where it hurt.
Ignoring Xu Chen's reaction, Gu Yao waited until some strength returned to his body. He got up, drank a healing potion, cleaned himself up, and decided to take a temporary rest. Then he picked up the Soul Refining Technique book recommended by Xu Chen and started reading. Xu Chen shook his head, unable to believe how efficient this kid was, wasting no time at all.
Gu Yao finally emerged, and Chi Changye breathed a sigh of relief when he saw him. He didn't ask what Gu Yao had been up to these past few days.
Gu Yao continued to practice the Star-Chasing Body Technique with Chi Changye morning and evening as usual.
After a few days, he felt that his body had fully recovered. Without a tool to detect spiritual roots, he examined the potion's effects by absorbing spiritual energy. Sensing a significant increase in the amount of external spiritual energy absorbed compared to before, Gu Yao was overjoyed.
If the amount of spiritual energy absorbed by a Heaven Spiritual Root in one breath is measured in a thousand units, the previous Gu Yao could only absorb less than fifty units. This was after purifying the impurities in his body. After taking the potential elixir, he increased it to nearly a hundred units in one breath. This could be said to have doubled his cultivation speed. Although he was still far from a Heaven Spiritual Root, it represented that Gu Yao had limitless possibilities to approach that goal.
