A public notice was posted seeking a wife, and a female saint from the Immortal Sect was found.

"This is the formula for the Foundation Establishment Pill. The Foundation Establishment Pill is used by Foundation Establishment stage cultivators. To refine the Foundation Establishment Pill, you must have the Spirit Transformation Grass as the main ingredient."

"Dragon Transformation Grass is quite valuable, and it usually grows in places where spirit beasts roam, making it relatively rare."

"This pill formula uses three relatively common medicinal herbs instead of the Dragon Transformation Grass, so it can be considered a treasure to alchemists."

Li Changqing and Chen Yi returned to the courtyard, and Li Changqing quickly wrote out a prescription and explained to Chen Yi the value of the prescription.

Chen Yi's heart skipped a beat after hearing this. He didn't understand alchemy, but he did understand that such an improved formula, which could replace an extremely precious main ingredient with three common medicinal herbs, was truly astonishing.

Only an alchemist could improve a pill formula, and an alchemist who could replace the precious main ingredient with three common herbs must be of an astonishingly high rank.

As far as he knew, the Purple Pill Sect had always focused on refining Spirit Condensation Pills, while Foundation Condensation Pills were rarely produced, presumably because Dragon Transformation Grass was relatively rare.

Therefore, this pill formula is extremely attractive to the Purple Pill Sect.

Immediately, Chen Yi thought of a question and asked, "How does this improved pill formula compare to the Foundation Condensation Pill made with Dragon Transformation Grass? If the effect is more than half as good, then the value of this pill formula is immeasurable."

Upon hearing this, Li Changqing glanced at Chen Yi and shook his head, saying, "You underestimate this pill formula. The Foundation Condensation Pill made according to this formula is at least 30% more effective than the one made with Dragon Transformation Grass."

Chen Yi: ...

I was still too inexperienced. I thought that using three common medicinal herbs instead of the precious main ingredient would be less effective, but it turned out to be 30% stronger than the original.

From this perspective, the value of the elixir immediately increased significantly.

"The formula is too precious, Changqing. How did you come to have such a formula?" Chen Yi asked.

He naturally knew that given Li Changqing's past strength and status, it wasn't surprising that he possessed such a pill formula. However, if he didn't ask any questions, it would seem unreasonable to Li Changqing.

Sure enough, as if he had been waiting for him to ask, Li Changqing replied without hesitation, "The pill formula was left by my late master. As for how he obtained it, it is no longer possible to find out."

In fact, she obtained this pill formula from the ruins of a cave when she was in the Nascent Soul stage, and it was not left by her master.

Chen Yi knew it was a lie as soon as he heard it, but he didn't ask any more questions. If he did, Li Changqing would have to go through the trouble of making up more stories, so he didn't want to make things difficult for him.

He then asked another question that required careful consideration: "The pill formula is so precious that it can easily attract the attention of the Purple Pill Sect. However, if we take out the pill formula, it may arouse the greed of the Purple Pill Sect. For example, if the Purple Pill Sect wants to keep the pill formula for themselves, they may attack our Chen family and destroy the Chen family, so that the pill formula will no longer be circulated."

This point cannot be ignored. Profits are tempting, and the Purple Pill Sect naturally wants to obtain the formula for the Foundation Condensation Pill, which can be refined at a cost dozens of times less than before.

Li Changqing glanced at Chen Yi with some surprise. She had actually considered all of these issues, but what surprised her was that Chen Yi was able to think of them so quickly.

"I've already considered it. The Purple Pill Sect can't possibly be without greed, but if they really want to make a move against the Chen family, they will definitely find out the true origin of this pill formula first, and they will also find out if the Chen family has any backup plans. And they can't find out either of these things," Li Changqing explained.

Chen Yi frowned slightly. Li Changqing spoke so casually, but he couldn't help but consider it carefully. After thinking for a while, he was immediately shocked.

Since Li Changqing is certain about the origin of the pill formula, the Purple Pill Sect certainly cannot find out. Furthermore, Li Changqing just said that the Purple Pill Sect will also investigate whether the Chen family has any backup plans, which is also impossible for them to find out.

He suddenly thought of Master Fang, who had long since left the family and was now hiding somewhere thousands of miles away.

Originally, this was a backup plan to deal with the Ning family. But now, the Purple Pill Sect will definitely be able to easily find out that Master Fang has already left the Chen family. So they can't help but consider that Master Fang may also have pill formulas.

Therefore, the Purple Pill Sect had to consider that if they attacked the Chen family, and Master Fang spread the pill formula, making it known to the whole world, then it would be a loss for them.

If the Chen family is not touched, the pill formula might only be available to the Purple Pill Sect. If the Chen family is touched, the pill formula is very likely to be spread throughout the world. Which choice would bring greater benefits is no longer worth calculating.

Thinking about all this, Chen Yi suddenly felt a chill run down his spine. It was hard to say whether Li Changqing had only just thought of this now, or whether he had already considered today's events when he sent Master Fang out.

If it's the latter, then it can only be said that Li Changqing's vision and planning are so terrifying that even he feels his heart pounding.

He hoped that Li Changqing had just thought of this; otherwise, it would be virtually impossible for him to fleece Li Changqing or persuade him to have children.

Chen Yi suppressed his thoughts, thought for a moment, and then asked, "If the pill formula is too precious, then we can't just ask the Purple Pill Sect to continue purchasing our medicinal materials. We must make more demands, otherwise it will be a case of losing more than we gain."

"That's natural," Li Changqing immediately said. "When handing over the pill formula, in addition to the medicinal materials, we should also make two conditions. First, the Purple Pill Sect must agree to protect the Chen family for three years. Those in high positions will not easily agree to the conditions of those in lower positions. If we propose three years of protection, the Purple Pill Sect will definitely try to pressure us down, and at most they will agree to protect them for one or two years. But our bottom line is that it must not be less than one year."

Chen Yi naturally knew that Li Changqing would be able to recover to the ninth level of the Qi Refining stage within a year. At that time, with Li Changqing's knowledge and skills, he might not be afraid of the Foundation Establishment stage cultivator from the Zhao family.

However, he still pretended not to understand and asked, "Why is the bottom line one year? Shouldn't it be as long as possible?"

Li Changqing raised an eyebrow and said, "With your demonstrated talent, you have a great chance of reaching the Foundation Establishment stage within a year. In that case, you will be able to protect the Chen family on your own."

Chen Yi laughed and said, "That makes sense, that makes sense. When I reach the Foundation Establishment stage, I'll protect you even if the sky falls."

Li Changqing ignored this and said, "The second condition is that the Zidan Sect sends us a batch of Spirit Condensation Pills and spirit beast blood. Of course, you can also ask the Zidan Sect to send us a spell. In short, make your request first. Whether the Zidan Sect agrees or not, we will not suffer any loss."

"However, there is a bottom line to this requirement: the number of Spirit Condensation Pills must not be less than one hundred bottles. With this batch of pills, it will be enough for your cultivation."

Chen Yi nodded repeatedly upon hearing this. If they could have a year of peace and a batch of Spirit Condensation Pills, then both he and Li Changqing would be in a different situation after a year.

"Who will go and discuss this matter with the Purple Pill Sect?" Li Changqing asked.

Chen Yi pointed to himself; this matter was of utmost importance, so he naturally had to go in person.

Li Changqing had no objection to this. Although Chen Yi was young, he was actually quite steady in his actions and should not make any mistakes.

The two discussed for a while and decided to go to the Purple Pill Sect the next day. Just as they finished discussing, a servant suddenly came to report that the Ning family and the Zhang family had come together to visit the Chen family.

Chen Yi raised an eyebrow. The Ning and Zhang families had already joined forces, and their sudden arrival at this moment was certainly not just a casual visit. The most likely explanation was that they were either trying to win over the Chen family to fight against the Zhao family, or they were using their power to intimidate others and prepare to annex the Chen family.

Regardless of the possibility, Chen Yi didn't bother to speculate. Since both the Ning and Zhang families had come, he would simply go and meet them.
