"Alright, can we sign the contract now? All those treasures have fully matured. As for how to use them, that's up to you. However, I must remind you of one thing: while these items are incredibly beneficial for cultivators, they also contain a toxin. It is precisely because of this toxin that you can perceive the different attributes hidden within spiritual energy. In other words, when you gain benefits, you will also pay a price. With your current strength, you can only choose two of the treasures to consume. Your current power can suppress the toxin, but if you exceed two, it becomes very dangerous. I cannot help you remove this toxin, because without it, these treasures would be no different from ordinary plants. Do you understand?"
Hearing this, Qin Feng finally understood. From the very beginning, he had felt that plant-based treasures were not that simple and must have some unknown side effects. He hadn't expected them to be poisonous. This poison not only had adverse effects on the body but also produced beneficial ones, making it a paradoxical combination.
With this thought, Qin Feng asked, "Since that's the case, can you tell me what kind of impact that toxin has on the human body? Is there an antidote? Can I develop an antidote so that I can consume more types?"
Upon hearing this, the mouth in the sky spoke, "I can analyze its impact on the human body, but I do not know where to find an antidote. This level of toxin has no effect on me, so I haven't paid particular attention to dealing with it. However, this toxin can have a very significant impact on humans, though it won't be immediately fatal. It's a slow-acting poison, and I believe finding a relevant antidote shouldn't be difficult."
After saying this, a peculiar energy directly entered Qin Feng's mind. The impact of that toxin on humans was like a transfer of knowledge, implanted deep within Qin Feng's mind, allowing him to instantly understand what this toxin was.
It was a toxin that, over time, would cause one's thinking to become increasingly rigid, one's intelligence to decrease, and eventually lead to idiocy.
However, this process was very slow. Once afflicted, it might not be discovered for a hundred or two hundred years. Every day, one's intelligence would decrease slightly. Although this degree of decline would not be noticed, it was real.
After being poisoned, one could indeed feel the different attributes contained within spiritual energy in a short period and could also temporarily increase their strength. But as time passed, their cultivation realm would stagnate. This was because as intelligence declined, the speed of cultivation would also slow down, eventually making it impossible to become an immortal. With the end of their lifespan, they would turn into a pile of dust.
Qin Feng couldn't help but exclaim, "What a vicious poison. I never imagined such a miraculous toxin could exist in this world."
After saying this, Qin Feng carefully considered methods to counteract this poison. With his current alchemy knowledge and deciphered prescriptions, he had many. He also had many prescriptions for enhancing intelligence, but none corresponded to this specific toxin. This meant he currently didn't have a miraculous elixir to counteract the side effects of these plant-based treasures.
However, the powerful being in the sky was knowledgeable and must possess more knowledge about alchemy.
With this thought, Qin Feng said, "Although you don't know how to counteract this poison, I believe you know a great deal about alchemy. Would you mind imparting this knowledge to me? I believe I can find some clues from this knowledge."
Hearing this, the eye in the sky looked at Qin Feng. Qin Feng immediately felt immense pressure.
His body became heavy, and he even felt as if his soul was about to detach from his body. It was an extremely uncomfortable process, and his life could vanish at any moment.
However, Qin Feng understood that the other party would not kill him. It was merely a lesson, urging him to make fewer demands and sign the contract quickly. But Qin Feng would not give up until he obtained sufficient benefits. He had to leverage his current advantageous position to demand more benefits, otherwise, once the contract was signed, he would no longer be able to bargain with the other party.
Therefore, Qin Feng straightened his back and looked at the eye in the sky, saying, "Imparting this knowledge is a mere trifle to you; you suffer no loss. Conversely, by obtaining this knowledge, I can enhance myself to a greater extent, making my strength even more formidable. Even after reaching the immortal realm, I can use this knowledge to help you break your seal. This benefits both of us. If you refuse, so be it. If, after I reach the immortal realm, I am unable to break your seal, do not blame me."
After saying this, Qin Feng suddenly felt a sense of lightness all over his body. The pressure vanished without a trace. Then, the mouth in the sky moved and said to Qin Feng, "I do know some things about alchemy. It all originates from your human race; it's rather ancient knowledge. Since you wish to know, I will impart it to you. However, I hope you will sign the contract soon and refrain from making further excessive demands."
With that, a wealth of alchemy knowledge flooded Qin Feng's mind. This was ancient, distant memory, filled with complex and profound knowledge, far surpassing the alchemy notes left to him by Elder Yao by more than ten thousand times.
Qin Feng was extremely excited because if he could fully digest and absorb this knowledge, the elixirs he could refine would possess extraordinary power. There were even elixirs he had never dared to imagine, and they were all present here.
Qin Feng was very satisfied. He nodded and then said, "This knowledge is very useful to me, and I believe it will help you break your seal in the future."
Hearing this, the mouth in the sky said, "Since that is the case, let us sign the contract, and then I will send you away. With your current strength, you can already walk sideways within the surrounding space. Even when returning to other worlds, with your current power, no one will be your match. As soon as the opportune moment arrives, you will have the chance to become a true immortal and help me break my seal."
Qin Feng did not agree with this. Although his current strength was formidable, he was only at the late stage of Void Refinement, not even having reached the Mahayana stage. It was unknown how long it would take to become an immortal. Even with the vast Red Alert legion as his helper, in the desolate lands where greater strength attracted more powerful monsters, he still faced great peril. As long as the curse above his head remained unlifted, his danger would not cease. Therefore, he needed more benefits.
With this thought, Qin Feng spoke again, "It seems my cultivation technique still has much room for improvement. I wonder if you could offer some guidance to further advance my technique and match my current strength."
