After reading this medicine scripture, Zhang Chenfeng took out another medicine scripture again.

But Zhang Chenfeng quickly put the book back.

In just a few hours, the entire bookshelf, books about potions, made Zhang Chenfeng turn over all the books.

After putting down the last medicine scripture, Zhang Chenfeng shook his head, these medicine scriptures really made him not interested at all!

"Hey, I really don't know if it's because the Shenwu Continent has a poor level in researching potions, or if the medicine scriptures collected by this Hell Golden Building are too rubbish?"

Zhang Chenfeng couldn't help but sigh in his heart.

Just as he was about to leave, Zhang Chenfeng suddenly noticed that this bookshelf was different from other bookshelves, and next to this bookshelf, there was a set of tables and chairs.

On the table, placed pen, ink, paper, inkstone, among which there was a black book.

"Xuantian Medical Sutra?"

Zhang Chenfeng looked through this book curiously.

"Huh?"

As soon as he opened this medical scripture, Zhang Chenfeng couldn't help but snort softly.

Because, this medical scripture is not an ordinary medical formula, but a formula that saves people with magic potions!

In the eyes of people, potions are harmful things, how can they be used to heal people?

"I didn't expect that in this world, there are people who do the same as I thought, refining strange beasts, fusing demonic energy, and using magic potions to heal people!

Zhang Chenfeng was a little interested again, and then opened it and looked at it.

However, seeing the first potion formula, Zhang Chen couldn't help but whisper in his mouth: "Junk prescription!"

"Silly fork! What kind of match is this?

"A small illness, refining with so many superb beasts, not only is the effect not obvious, but it makes people terminally ill!"

"The best! the best of fools!"

......

Zhang Chenfeng couldn't help but scold while watching.

"Hmm? This potion formula is okay, it can indeed cure heart disease, but the side effects are too great! The heart is fine, but the muscles and bones suffer, every morning, noon and night will be painful, where is this to save people, it is simply to make people can't survive, can't die! Hey......"

Zhang Chenfeng really couldn't stand it anymore, so he casually picked up the brush on the table, modified the last potion formula, deleted the redundant formula, and added only one material.

Then, Zhang Chenfeng threw the pen in his hand, got up and left.

What "Xuantian Medical Sutra", this kind of garbage medical scripture, Zhang Chenfeng will not read it even if he is killed, it simply affects people's IQ!

......

After Zhang Chenfeng left for a while, Ye Xuantian took Lu Wei to the library building, and came to the place where Zhang Chenfeng had just read the book.

Ye Xuantian walked to the table, and while sitting down, he spoke: "Lu Wei, bring the 'Catalogue of Alien Beasts' and the 'Alien Beast Medicine Sutra' for me! I thought of an excellent prescription for using magic potions to treat muscle and vein injuries today!"

"Yes, Master!"

When Lu Wei heard the order, he immediately ran to the bookshelf to find the book.

Ye Xuantian looked at the book of "Xuantian Medical Sutra" written by himself on the table, and said with a smug face: "Hmph, what if the potion master can get rid of the potion? Lao Tzu can refine foreign beasts to heal people! Everyone is afraid of foreign beasts, and only a genius like Lao Tzu can think of refining magic potions to heal people! Old man Wang, old man Li, you wait, wait until I perfect these prescriptions, and see if you dare to say that Lao Tzu is a simple-minded person!"

Lu Wei, who was looking for books on the side, heard Ye Xuantian's words, and the corners of his mouth suddenly twitched a few times.

He naturally knew who Old Man Wang and Old Man Li were in Ye Xuantian's mouth, they were the other two protector generals of the Heavenly Fire Empire!

Except for the martial arts realm being stronger than them, his master had never won in other aspects, especially in terms of knowledge!

Lu Wei sighed secretly in his heart: "Master, Master, it's easy to refine potions to kill people, but it's too nonsense to use potions to save people, it's just what your old man imagined?

Ye Xuantian naturally didn't know that his apprentice had so little confidence in him, but he felt that his idea was right!

He opened his own "Xuantian Medical Sutra", and when he turned to the last prescription, he saw that the prescription he had written had been cut by half, his eyes opened suddenly, and the anger in his heart suddenly came up!

"Bang!"

Ye Xuantian slammed the table and said angrily: "Damn, which idiot changed Lao Tzu's prescription? Didn't Lao Tzu say that no one should touch my book!?"

Lu Wei, who was looking for a book, was startled when he heard the master's roar.

Although Lu Wei was very jealous of foreign beasts, and he didn't like Master's refining potions, he knew that this potion formula meant to Master, it was simply Master's reverse scales!

"It's over, it's over! This is the master's prescription, don't you know that this will anger the master?

Lu Wei looked at Ye Xuantian, who was thundering, and his heart was very frightened at the moment!

After Ye Xuantian scolded angrily, his eyes stared at Lu Wei fiercely, and asked: "Lu Wei, you are responsible for most of the things in the Golden Building, and you are clear about the slightest disturbance in the Golden Building, you should know who moved my prescription, right?"

Lu Wei chuckled in his heart, and said with a wry smile: "Master, I really don't know who used the prescription! Everyone is very afraid of foreign beasts, let alone using foreign beasts to refine potions! Everyone will not approach the bookshelf here at all! Moreover, Master, you have also given an order, no one is allowed to approach near this table......"

In the middle of his words, Lu Wei's eyes suddenly flashed, and he quickly changed his words and said, "Master, I know who it is! Zhang Chenfeng! It's Zhang Chenfeng! He is reading a book around here today, and your prescription must have been moved by him!"

"What! is that piece of shit!?"

Ye Xuantian frowned, gritted his teeth and said, "You idiots, why don't you look at him!, how can you let him mess around in the library!?"

"Master...... Didn't you say you didn't have to worry about him......"

Lu Wei said weakly......

Hearing this, Ye Xuantian was stunned, and then his eyes widened, "You mean to say that it's all my fault?"

Lu Wei's face changed greatly, and he hurriedly bowed his head and said, "Disciple doesn't dare!"

"Humph!"

Ye Xuantian snorted coldly, waved his big hand, and said coldly: "Go and throw Zhang Chenfeng out of the Golden Building! A waste who only knows women and has no martial arts dares to touch my baby! He deserves to be killed!"

"Okay Master, I'm going to blast Zhang Chenfeng out!"

Lu Wei saw that the master didn't blame him much, and asked him to throw Zhang Chenfeng out of the Golden Building, and he instantly came to his senses!

Ye Xuantian already looked down on Zhang Chenfeng, and just took advantage of this to drive Zhang Chenfeng out, even if the Zhang family knew, they didn't dare to say anything.

It's just that Ye Xuantian felt a little distressed about his prescription......

"This damn waste, Lao Tzu's hard-working and hard-working prescription, you also changed it for me, if it weren't for your Zhang family's kindness to me, Lao Tzu really wanted to shoot you to death......"

Ye Xuantian muttered...... Suddenly, his voice stopped!

He looked at the prescription with a shocked face, the places that had been altered!

"Oh my God, how did I forget this! The demonic energy of this black-winged ice snake, mixed with the demonic qi of the man-eating flame flower, will be completely neutralized and will have no effect! And this krakentail beast cannot be refined with the bloodthirsty fish, otherwise the demonic qi will go berserk and corrode people's meridians...... Replacing the bloodthirsty fish with the Purple Flame Bird is the perfect match......! It's a stroke of genius!"

Ye Xuantian looked at the prescription at this moment excitedly, and finally couldn't help clapping his palms and cheering softly: "It's good! It's wonderful! It's really genius!"
