Han Li picked up a jade cylinder and blew it gently, revealing its true green face.

He pressed the jade cylinder against the corner of his forehead, and his mind slowly sank into the inside of this thing, and a method of refining the pill appeared in front of him, it turned out to be the Zhuji Pill refining method that Han Li had dreamed of, from the raw materials to how to condense the whole process into the pill, which made him surprised and delighted.

He didn't bother to look at the other jade cylinder for a while, and hurriedly browsed through the entire content with his mind first. But when the words "must be tempered with innate true fire in order to become a pill" passed through his mind, Han Li was stunned, and he felt completely dumbfounded.

The innate true fire is the Taoist Gang fire that only monks can have during the foundation building period, and it is a basic magic energy that immortal cultivators after foundation building are born with. It will gradually increase in power with the monk's refining and meditating, and even after the Dan Formation Period, this true fire will turn into the legendary fire of the three flavors, which can burn all things in the world.

But this kind of innate true fire, how could Han Li in the Qi Refining Period cast it? Only after the foundation was built, could he use it.

However, if the foundation is built, it must be refined into the Zhuji Dan, and the innate true fire after the foundation is refined, so that an interlocking and inextricable monster is formed.

It made Han Li depressed and felt the urge to hit the wall!

Finding other monks in the foundation building period to help with alchemy is even more impossible. This is equivalent to exposing the secret of the small bottle to the other party, and at that time, I am afraid that the helper invited will become the murderer who wants his own life.

Han Li stood at the table and was distraught for a long time before he took the jade cylinder off his forehead and put it back in its place. Then absentmindedly picked up another jade cylinder and wiped it a few times, revealing a fiery red color.

"The matter of Tsukidan, I can only think about it later!Let's see what the contents of this piece are first, maybe there will be other wonderful pills in it!" Han Li was also a decisive and resolute person, and immediately put aside the Tsukidan's advance and checked the red jade cylinder, hoping to give himself a big surprise.

"Dingyan Dan", as soon as Han Li's mind entered it, these three words appeared in his mind. He suddenly felt a little uncomfortable, but Han Li still comforted himself. "Although the name is so, the effect of the elixir may not be what I think, maybe there are other miraculous effects!"

But the next few sentences completely shattered Han Li's extravagant hope, "It can make youth last forever and appearance lasts forever" This is the description of the effect of this pill, and there is no other effect!

Han Li stood there motionless as if he had been frozen, not saying a word. But in his heart, he could no longer suppress the evil fire that was rising, and secretly cursed.

"What kind of library is this, how can there be no recipe, but it's a mess, and I have a lot of collections! What kind of golden needle secret technique, fixing pill and the like, what kind of ghost can we immortal cultivators do, they are also placed here in a big way......

Just when Han Li felt that this trip was almost in vain, that nasty voice came up again.

"The time has come again, if you ...... again"

"It's down!"

Han Li didn't have much to say this time to give the other party a spirit stone for nothing, so he picked up the jade cylinder containing the Zhuji Dan refining method and prepared to leave here.

But as he walked at the top of the stairs, he hesitated. I felt that although that "Fixing Yan Pill" did not help to improve mana in the slightest, it seemed that it could still be sold to other immortal cultivators. And the most important thing is that this Dingyan Pill does not need the so-called innate true fire, and now he can mix it.

Thinking of this, Han Li turned around and ran back to the table, grabbed the red jade cylinder in his hand, and then quickly returned to the staircase and went downstairs.

"How is it, little friend, have you gained anything?" As soon as the old man saw Han Li coming down, he immediately asked with a smile on his face, but how could Han Li hear and feel that this was so hypocritical.

"Old Xu, is the upstairs really the place where the secret recipe of the elixir is stored in this door?, why is there just such a piece of rubbish and garbage, there won't be other collection rooms, right?" Han Li didn't care about the old man's ridicule, but instead asked the question that had been held in his stomach for a long time, with a depressed expression on his face.

Seeing Han Li's expression like this, the old man couldn't help but laugh.

"Since the old man took care of this place, Xiaoyou is not the first person to have this question. Almost every newcomer who has just arrived at Yuelu Hall and watched it upstairs will ask the old man about it. But I want to know the reason for this......" This Xu Lao deliberately dragged out his tone, but the meaning of wanting benefits in his words could not be clearer.

The other party's expression of asking for money really made Han Li speechless. The person in front of him is still a monk in the foundation building period, and it is clear that the profiteers of the secular world have arrived here, and he looks like an iron rooster.

At this point, Han Li finally understood the other party's intention to call him Uncle Sun instead of him. This person obviously felt that if he became an elder of the division, it would be difficult to blatantly ask for benefits, so he played such a small trick to cover his ears and steal the bell.

Han Li raised his eyebrows, and without saying a word, he "snapped" and "snapped" twice, and placed the two jade cylinders in front of the old man's table.

"The junior originally wanted to copy both jade cylinders, but now that I look at it, the spirit stones don't seem to be enough! "Han Li hadn't been in the secular realm for so long, so he fought back a little bit, just in case the other party's appetite grew bigger and bigger.

"Xiaoyou wants to make two copies?" Boss Xu was overjoyed, his eyes widened.

"Originally, yes, but the juniors still want to know the answer to the question just now, and it doesn't seem to be enough!"

"Hehe, since Xiaoyou is so refreshing, of course the question just now is free. The old man will copy it for Xiaoyou first!" the old man hurriedly copied the two jade cylinders in his hand, and then took out two white jade cylinders from the shelves behind him, and hurriedly copied them, looking like he was afraid that Han Li would regret it.

"The copy is complete, take it!" The old man's movements were extremely agile, and in Han Li's stunned eyes, he had already finished copying the jade cylinder, and then threw the copy in front of Han Li's eyes. Then, with a look that you didn't take out the spirit stone yet, he looked straight at Han Li.

The corners of Han Li's mouth twitched, and he wanted to say something, but he still didn't say it. After a little silence, he cleanly took out twenty low-rank spirit stones from the storage bag and handed them to the old man without saying a word.

The old man took these spirit stones with a smile on his face, and he couldn't close his mouth with joy for a while. It wasn't until he had checked these spirit stones three or four times in a row that he noticed that Han Li on the side was still waiting for his reply.

At this time, Xu Laocai put away the spirit stone with satisfaction, and looked at Han Li again with the eyes of a big financier.

"It's really unseemly! Xiaoyou has such a deep net worth, which is really unexpected to the old man. However, although the old man loves money, he is also a man of promises. If you have any problems today, just mention it, the old man will definitely make Xiaoyou satisfied!" After the old man withdrew his gaze, he unexpectedly showed a solemn and square image, and said solemnly.

Han Li was slightly surprised, but he unceremoniously asked to answer the question just now.

"In fact, the answer is very simple, most of the elixir formulas have long been lost. This is not only the case for us in the Yellow Maple Valley, but also for several other families, and even the entire Immortal Cultivation Realm!" the old man said slowly.

Han Li was stunned when he heard this, and looked at the old man with some puzzlement.

"Actually, Xiaoyou calmed down and thought about it, and you will understand. What is the value of the elixir formula? Of course, it is because we can turn the corresponding heavenly and earthly treasures into elixirs for immortal cultivators like us. ”

"But Xiaoyou has not thought about it, the natural materials and treasures in this world are very limited, and it takes hundreds or even thousands of years for each type of growth to become successful. However, the number of immortal cultivators has never decreased, and is even increasing year by year. As a result, the various raw materials recorded in the recipe are gradually scarce, and even slowly and completely extinct. By the time the people in the Immortal Cultivation Realm noticed the seriousness of this problem, the heavenly treasures in this world had already been excavated, and only a little bit of some special places remained, but these places were extremely dangerous even for immortal cultivators who had achieved cultivation, and they would not take this danger easily. ”

"In this way, the formula that completely cut off the source of raw materials will become worthless, and who else will pay attention to it? After an extremely long period of time and several catastrophes in the Immortal Cultivation Realm, those elixir formulas have gradually disappeared into history, and there are only a few left. And Tsukidan is just one of the ones that survived. ”
