"Hahahaha!" Looking at Lin Feng's deflated look, Tianyi couldn't help laughing.

"Young people should look like young people, don't be so boring every day. Tianyi smiled at Lin Feng, teasing his apprentice who had just been accepted.

"Whew..."Lin Feng always felt that there was a vicious aura in his heart, and he couldn't play it.

I can't beat it, I can only complain about two sentences.

"The boss is not small, teacher, you can be mature!" If you don't know how to fight, you really can't stick to Tianyi's poisonous mouth, Lin Feng also gave Tianyi this habit.

"Okay, don't talk nonsense with you kid, this thing does sound familiar to me. Tianyi waved his hand, signaling that he would not bother with the child, but his words changed in vain, and he switched to the brown and black potion in his hand.

"Oh?" Lin Feng's eyes lit up slightly, revealing a look of anticipation.

"The potion in this seems to be of great benefit to my cultivation, but I'm not sure if there will be any side effects. That's why I came to ask the teacher about you. Lin Feng explained the reason and told Tianyi about his difficulties.

Although Tianyi would not give Lin Feng anything material, he did give Lin Feng the most important thing, that is, knowledge!

There is an old man in the family, if there is a treasure, this is the truth, at least in Lin Feng's opinion, Tianyi is indeed a very competent teacher, knowledgeable, of course, it would be best if he could get rid of that poisonous tongue and be familiar.

Thinking of this, Lin Feng couldn't help but complain a few words in his heart.

"This thing should only be available in the United States and Dongying, and it is difficult for us in China to see this kind of thing. Although Tianyi's words meant probability, his tone was very calm, obviously very confident.

"That's true!" Lin Feng suddenly became confident in his heart, because Li Shun had also explained to himself like this before, and this kind of potion was rarely produced within Huaxia Kingdom.

It is only available in foreign countries, which also makes it difficult to obtain sources of scarcity.

"This thing must be a combination of Changeable Water and some strange things. Tianyi thought for a moment and gave Lin Feng an exact answer.

"Ten Thousand Changing Water?" Lin Feng had a look of doubt in his eyes, obviously he had never heard of this name, but it was also normal, after all, he was no longer a novice in the cultivation world, but there was nothing wrong with saying a rookie.

I still know too little, even if I have been browsing the website of the cultivation world these days, it is impossible to remember everything at once.

"Yes, the water of change, this liquid looks the same as water, but it can only be produced by some unique environment, it is non-toxic and harmless, and even if you drink it as mineral water, there is no problem. Tian Yi nodded, touched his somewhat sparse and gray beard, and said affirmatively.

"But as the name suggests, everything changes, and the value is that his compatibility and mutagenesis are very high, and there will be some unexpected changes when combined with other things, maybe it's poison, maybe it's an antidote, or maybe it's... Chun..."Speaking of this, Tianyi smiled at Lin Feng, revealing an expression that everyone understands.

"Stop!" Lin Feng suddenly interrupted Tianyi's next words with an indifferent expression.

"Can you tone it up a bit!" Although Lin Feng's face was expressionless on the surface, if you look closely, the black line on his forehead is coming out, and the green tendons are faintly visible.

"Young people now....." Tianyi shook his head and sighed with some embarrassment.

Tianyi's thinking is simply weird, he may be serious with you in the last second, and he will be giggling with you in the next second, and he looks like an old naughty boy who is alive.

"First of all, I want to know, what kind of substance in it has the effect of promoting your cultivation, is it the Ten Thousand Changing Water?" Tianyi wiped his beard, and under the surface of the grin, there was a hint of wisdom in his eyes.

"No, although the Ten Thousand Transformations Water has a wide range of uses, so far, it seems that it has not discovered any effect on its own, let alone promoting human cultivation. Tianyi analyzed it with a calm bearing, which was completely different from the usual out-of-tune appearance.

"Maybe it's my physique, or maybe my... It is also possible that the exercises and the water of change have a special harmony. Lin Feng put forward his opinion, because he had always felt that the exercises he had obtained from the two major spaces were not simple.

It's definitely not a Xuan-level, or even a king-level exercise that can be compared, just like Shentan, the two exercises gradually show their particularity.

"It's possible, but you first need to separate the substances. Tianyi also said thoughtfully, and immediately handed the potion to Lin Feng.

"Find a way to separate the substance yourself, old man, I don't have a way to separate it here. Tianyi waved his hand and motioned for Lin Feng to figure out a way by himself.

"Hospital..."Lin Feng suddenly had a flash of inspiration and blurted out.

"Indeed, according to the current technology, it is not difficult to separate this kind of micro materials, any big hospital should have a channel, the key is whether you can go through this channel. Tianyi hinted to Lin Feng that people can't work behind closed doors, but also have to intersect in society.

"It's natural, I still have channels. Lin Feng could naturally hear the teacher's hints, but he didn't panic at all.

Because he does know someone who can help him, and that is Luo Hai!
