A freshman who has just entered the school actually said that he can understand this book, he has also read this book, and there are many insights in it, and he can't fully understand it!

However, thinking of Xi Yue's outstanding talent, Zeng Shouyue still took the book from Xi Yue's hand.

What is written above is the simplest recipe for the blood tonic pill, and it is the blood tonic pill of the three grades, and this kind of blood tonic pill is also very popular in the current Miluo continent.

Zeng Shouyue looked at it and made sure that the pill of this blood tonic pill was the same as his common pill, and he couldn't help frowning and said, "Isn't this just an ordinary blood tonic pill?" What's the problem? ”

These pills have been used for thousands of years, and no one has ever raised a question. How could there be a problem?

However, thinking that Xi Yue is only seventeen or eighteen years old now, it is the age when he is suspicious and asking, and the newborn calf is not afraid of tigers. He was relieved again.

Putting it on the table, Zeng Shouyue touched his beard and said with a smile: "If you have any doubts, you can go to my alchemist and try refining a few times, as long as you refine it, you will know the essence of this pill." It is also understandable why such a Danfang can be spread in the Miluo Continent for thousands of years. ”

Su Xi shook his head and chuckled: "I don't need to refine it to know that there is a big problem with this Danfang." ”

Zeng Shouyue was a little displeased at this moment, but he still calmed down and said, "Then you can tell me, what's wrong with this Danfang?" ”

The library was always quiet, and many of the students were attracted to the debate between the two.

Originally, some people wanted to reprimand the two for arguing, but when they saw the identities of the two clearly, they all shut up.

Especially when everyone found that Zeng Shouyue looked at Xi Yue's unkind gaze, they immediately guessed that Xi Yue was disgusted by this branch dean, and they couldn't help but gloat.

It's just that Su Xi was unaware of everyone's onlookers and Zeng Shouyue's displeasure, he just stretched out his slender fingers like jade and tapped the book gently, and said in a faint and steady voice: "In this pill, there are two main medicines, namely Fire Essence Jujube and Xuanbing Flower. The fire essence jujube produces blood, and the Xuanbing flower moistens the veins, if the two are separated, there is no problem, but if the two are fused together for alchemy, then there is a problem. ”

Without waiting for Zeng Shouyue to ask again, Su Xi continued: "Although in terms of efficacy, these two spiritual grasses do not clash with each other, but they themselves belong to fire and water, one belongs to yang and one belongs to yin, and they are fused together, and the medicinal properties of the two are offset by yin and yang, and although refining into an elixir is not harmful to the human body, it greatly wastes the value of the elixir itself. ”

"Moreover, once the amount of Fire Spirit Jujube and Xuanbing Flower is not placed properly, it will make the elixir contain cold poison or fire poison, and if this elixir is taken for a long time, the martial artist's body will definitely be harmed. Dean Zeng, what do you say? ”

Zeng Shouyue was already stunned at this time, staring at the young man in front of him with wide eyes, and muttered after a while: "Yin and Yang are offset? That's right, if it's really one yin and one yang, will it really be yin and yang? ”

The onlookers were even more in an uproar when they heard Xi Yue's words, some were disdainful, some were puzzled, and some were shocked.

"What yin and yang are offset, I think it's all nonsense from him, this is a Danfang that has been passed down for thousands of years, can Xi Yue still be able to change it himself?"

"I think what Xi Yue said is not unreasonable, I heard that some people who take inferior blood tonic pills will be inexplicably poisoned by fire."

"I've never heard of anyone who can change the pill by himself, what if the refined pill eats someone to death?"
