"You're thinking too simply. Li Cheng rolled his eyes and directly gave Yang Chen a roll of his eyes: "For thousands of years, do you really plan to stay in the mortal world for thousands of years, and become an old antique of a person's immortal ten grades?"

Of course, Yang Chen didn't want to become like Elder Feng of the Taitian Gate, and the Pure Yang Palace was not the Taitian Gate, so he could still develop in the Spirit Realm without Yang Chen flying to the Spirit Realm.

His head shook like a rattle, and Yang Chen didn't need to speak, he just shook his head to express his attitude.

"Don't want to, do you think I can help you?" Li Cheng hit Yang Chen's confidence again, and his words were unprecedentedly serious: "If it can be refined for thousands of years, it will still be a good thing, I'm afraid that you won't be able to refine until your longevity is exhausted, what will you do then?"

"Can't you soar and refine it when you reach the spirit realm?" Yang Chen really didn't know this time, such a high-level product as Slashing Sendai, Yang Chen hadn't had the opportunity to have more contact in his previous life, he just knew some common sense, and he didn't know the real core things at all, so he immediately asked Li Cheng for advice.

Yang Chen never thought that there was anything embarrassing about asking people for advice, and he didn't have that kind of arrogant stink when he was reborn once. Especially if the person who asked for advice was Li Cheng, then there was no psychological burden, and he waited for this sworn brother to solve his doubts with peace of mind.

"When the Tribulation Soars, if you fail to refine it thoroughly, you will be directly dragged down by the entrances and exits, and the only result of the confrontation between the two sides of the space is that you will be wiped out. Li Cheng shook his head slowly, giving Yang Chen such an answer that he had never thought of.

According to Li Cheng, if Yang Chen couldn't refine the entrance of the Immortal Cutting Immortal Terrace in the mortal world, he could only stay in the mortal world and slowly wait for the longevity to run out. Yang Chen never doubted that Li Cheng would deceive himself on this point, which did not benefit him at all, and it was meaningless.

"There is a way to run out of longevity. The younger brother found a pill that can prolong the longevity, and refining a batch can increase the longevity a little. Yang Chen also became serious, and said slowly: "However, there is no other way but to stay in the mortal world?"

This time, Li Cheng did not answer directly, but showed a rare expression of surprise, and asked in disbelief: "You have found a pill that can prolong longevity? How is it possible! A five-grade alchemist in the world can refine an elixir that prolongs life? That is the effect of the Nine Turns Golden Pill." ”

"I can't say that I found it, and my little brother was also inspired. It's just that the feasibility has been discovered. Yang Chen heard Li Cheng say this, but he didn't make a fool of himself, but just said lightly.

This is not that Yang Chen is lying, the Dan prescription of the Longevity Pill found from the Pure Yang Palace Secret Pavilion is not complete, and even most of it is just a concept. The only constructive breakthrough is to use pure yang true fire and pure yin true fire to alchemy at the same time, and yin and yang are just combined. From the materials to the techniques, Yang Chen referred to the Lao Jun Dan Sutra, combined with his own cultivation of Yi Lao Mo's magic skills that can absorb the essence of other people's lives as a reference, which gave a prototype.

The essence of Danfang is mainly two parts, the first is the joint refining of pure yin and pure yang true fire, and the second is the method of absorbing the essence of life. Yang Chen's main ingredient is a human-level demonic bead, and it is precisely because the demonic bead is condensed from the life essence of the demonized demon beast and can be absorbed.

However, Yang Chen was only a fifth-grade alchemist after all. Even with the help of the Yunling Furnace, he could barely refine the lowest-grade six-rank pill, but the limit was just that. Compared with the Nine Turns Golden Pill, I don't know how bad the effect is.

Don't say anything else. You can see the increase in longevity alone. A person's Immortal Immortal Immortal Bead of more than five grades contains such a terrifying life essence, but it can only extend the lifespan of a mortal master for a hundred years. The efficiency of the conversion is poor to grandma's house.

But having said that, from another aspect, Yang Chen was able to use the pills and fire in the world to refine the elixirs that increased longevity at the level of a fifth-grade alchemist, even those eight-rank and nine-grade alchemists in the immortal realm might not be able to do it, and at this point, Yang Chen was definitely something to be proud of.

"Tell me about the principle of your Danfang for longevity, and I'll listen to it. Li Cheng was obviously interested, and no longer talked about the entrance of refining and slashing immortals, but instead began to ask Yang Chen about the Dan prescription of the Longevity Pill.

Yang Chen did not hide it, and told Li Cheng word for word the final version of the Danfang that he had now summarized, and the refining technique was not left behind. I didn't say much else, the fire Li Cheng was more mature than Yang Chen, the Demon Demon Bead Li Cheng also came into contact earlier, and the alchemy experience Li Cheng was definitely not bad, so Yang Chen didn't need to do too much explanation.

Li Cheng fell into deep thought, closed his eyes, and began to slowly ponder in his mind whether the elixir refined according to Yang Chen's pill had the effect of prolonging life.

Here Li Cheng was pondering, Yang Chen didn't bother him, he was silently thinking about how to solve the dead end of refining and slashing the entrance of Xiantai.

Yang Chen was indeed a little greedy and careless. I thought that if I could refine the core of the Demon Continent, I would also be able to refine the entrance to Slash Sendai, but now with Li Cheng's reminder, I looked back and found that it was not like that.

The core of the Demon Continent was only a point at best, no more than the size of Yang Chen's little fingernail at most. It took Yang Chen hundreds of years to complete this, and it was only completed with the help of the Heavenly Tribulation during the Yin Fire Tribulation.

The entrance to the Immortal Terrace, but Yang Chen, a big living person, swaggered in, and it looked extremely wide. In terms of size, it is hundreds of millions of times larger than the Demon Continent. Not to mention anything else, just at this scale, according to the proportion, Yang Chen's refining time would also increase by hundreds of millions of times, not counting the difficulty that would increase at the same time after the space increased.

It would be nice if Yang Chen wasn't so greedy at that time, but it's too late to say anything now. The entrance to the Slashing Immortal Terrace had already undergone the first level of sacrifice and was tightly tied to Yang Chen, and Yang Chen had not yet found a way to break this connection.

In his mind, he went through the technique of refining the space word by word, but Yang Chen was still disappointed after all, there was no quick way to refine this exercise, and there was no means to give up in the middle of refining. In other words, Yang Chen had to completely refine the entrance of the Slashing Immortal Terrace in order to get rid of the doom of being wiped out when he ascended.

"Your method is kind of interesting. Yang Chen was pondering here, and Li Cheng was not idle, and soon it seemed that he had figured out a lot of things, and opened his eyes and said to Yang Chen: "Pure Yang True Fire plus Pure Yin True Fire, there is such a method of transferring the essence of life, it is ingenious!"
