The wind attribute internal qi and the thunder attribute internal qi in the body are attacking each other, although the two are not incompatible, but one mountain cannot tolerate two tigers, both of which will occupy Yu Qiu's meridian dantian important land, and they will clash in an instant.

Yu Qiu's mind was racing, from what he knew before, ordinary people only practiced one kind of exercise during the Qi cultivation period, and no one practiced two at the same time like him, it turned out that it was because the internal qi would conflict with each other.

"Is it possible for the two internal qi to merge?" Yu Qiu pondered.

"Practice Qi, practice Qi...... Refining!" Yu Qiu thought of the refining technique, the dual-attribute fusion refining technique.

"Try it!"

After only trying for a while, and after failing twice, Yu Qiu succeeded the third time, and the principle of the two is actually very similar......

The night passed, and Yu Qiu let out a long breath. This night, he practiced the same thunder-attribute internal qi as at the beginning of the previous qi training, and then the thunder-attribute internal qi and the wind-attribute internal qi merged into one.

The overall quantity is still at the beginning of Qi training, but the quality is twice as much.

It's like the idea of compounds.

Yu Qiu was embarrassed, the quality of the internal qi was twice as strong, and it became a dual-attribute internal qi, but the total amount was still in the early stage of qi training.

The reabsorption of internal qi will no longer increase the total amount, and the newly added internal qi will be instantly destroyed by the dual-attribute internal qi in the body.

"It's better to go to the medical school later and ask Elder Luo. ”

In the morning, Qingxue hurriedly finished eating breakfast and began to practice Tai Chi again, and the morning light sprinkled on her, forming a beautiful picture.

However, Yu Qiu didn't have much time to admire, and he ran to the medical school building.

The fourth elder introduced him to the medical school building, this place has been abandoned for a long time, before the four academies were separated, this place everyone wanted to fight, and it has not been fought for by any party.

Open the door to the medical school building, cobwebs and dust are everywhere.

But with a flick of Kazuchu, a strong wind blew, and the dust and cobwebs disappeared with the wind in an instant.

Yu Qiu is secretly envious, the kung fu is high, and the cleaning is easy!

As the dean of the medical school, although it is a hidden version, Yu Qiu still feels that he needs to have a snack and get to know this building carefully.

"This building seems to be quite old?" Yu Qiu said.

"This building has been built for more than 500 years and was built by the former medical saint and his master. Wu Xuan said.

"Medical Saint?" Yu Qiu asked curiously.

Wu Xuan's eyes shone brightly: "Back then, the medical saint Bai Di was proficient in alchemy, medicine, pharmacy, and toxicology, and no disease was difficult to defeat her, and she was the most respected figure in our medical school. ”

Liu Qianyu's illness is in the hands of the medical saint, I'm afraid it's also a piece of cake!

"Then why was it divided into four disciplines later, wouldn't it be nice to study together?" Yu Qiu asked the question he wanted to ask the most, since these four disciplines were all related to medicine, why should they be divided into four subjects to study.

Yan Wu said with a slight disdain: "These four are all broad and profound, it is difficult for ordinary people to specialize in one of them, how can they be proficient in all four." He seemed to think that Yu Qiu's question was quite naïve.

"But Yu Qiu is possible!" Luo Qingshan helped Yu Qiu speak.

Yan Wu still said disdainfully: "Hmph, boy, I'll talk about the front, although you are the dean, but the poison science has not surpassed me, don't really want to gain my respect." ”

Seeing that the atmosphere was awkward, Ge Qiu made a round: "Dean, Yan Wu is straightforward, don't mind." ”

Yu Qiu laughed: "It's okay, if you have something to say, it's better to say it directly than to keep it in your heart." ”

The first time I saw Yan Wu, I felt that this person was quite gloomy. But in fact, judging from his speaking style, he doesn't seem to have much scheming.

As they spoke, they entered the library.

Wu Xuan said again: "In fact, the four kinds of knowledge are suitable for people with different spiritual roots to specialize, so it is difficult for someone to have more than one at the same time. ”

Yu Qiu became interested, and recently happened to be confused about the matter of Linggen, so he hurriedly asked, "What is the specific situation?"

Ge Qiu replied, "I am the best fire spirit root, suitable for alchemy, Wu Xuan is the best wood spirit root, suitable for medicinal plants, Old Man Luo is the best gold spirit root, suitable for surgery, and Yan Wu has the best qualifications, which is a semi-innate dark spirit root, suitable for toxicology. ”

Yu Qiu secretly said No wonder, Yan Wu looked the youngest, but he could be ranked with the other three elders. He is also the most arrogant, the most impulsive, and the original qualifications are the best.

Wu Xuan added: "However, although the wood spirit root is suitable for medicinal plants, it also has a good effect when used for alchemy. ”

"So, wouldn't it be best if you had four spirit roots at the same time?" Yu Qiu asked.

All four laughed at the same time.

Wu Xuan explained: "A person's affinity is up to 100%, and even if the four spiritual roots are all 25%, then each of them is acceptable, but it is not particularly good. ”

From a certain point of view, the spiritual roots are evenly divided into many kinds, but they become miscellaneous spiritual roots, which is not better.

Although all four types of learning can be learned, the upper limit is limited, and it is difficult to develop to a high level.

Yu Qiu continued to ask, "Is there any situation where a person has a 100% affinity for multiple spiritual roots at the same time?"

"Impossible!" the four said in unison.

Yan Wu was the most sarcastic: "Boy, are you very bad at math, if you divide it into four points, how can it be one for every point." ”

Yu Qiu secretly thought, it seems that these elders can't help his own situation, maybe this situation has never happened.

"Then the medical saint Bai Di, how can he be comprehensive?" Yu Qiu asked again.

"So this is the legend of the ancients, this is the only one, and there is no other place. Luo Qingshan sighed, and there was admiration in the eyes of the four elders at the same time.

They explained Yu Qiu some precautions, and left him familiar with the environment in the medical school, which is about to start, and they are also very busy, especially the reunification of the medical school, and there are many things to deal with.

In the library, there are many more books than Yu Qiu imagined, from the most basic books in medicine to the most difficult books.

Unlike the Gongfa Pavilion, there are physical books on this side, but it can be seen that they are all manuscripts, and they should have been preserved in a special way.

Among them, a special place is a set of books.

"Evergreen Sacred Text"

"It seems that this is the most advanced book in medical school. ”

As the dean's perk, Yu Qiu can read all the books of the medical school at will.

Yu Qiu picked up the Evergreen Sacred Scripture, and the first page of the inner page listed the basic courses.

To read this book, you must have reached a considerable level of pills, medicines, poisons, and all kinds of medical methods to read it.

Yu Qiu tried to flip through it, even if he used the reverse probability system, it was impossible to understand it.

The other four subjects must be added to a certain extent.

"To learn the other four disciplines, my qualifications are not the most suitable, unless I can cultivate the other four innate bodies. ”

Yu Qiu activated the reverse probability system: "Find a book suitable for cultivating the innate body......"

Yu Qiu took out a copy of the "Spring Tree Body Refining Method" from the vast number of books.

Yu Qiu was overjoyed in his heart, and hurriedly looked through the preparation for cultivation, this book was suitable for the cultivation of the wood attribute spiritual root.

The content of the book is not difficult, and the principle is simple, but Yu Qiu found that there was no way to cultivate at all, and he did not have a single wood spirit root in his body now.

But can this be difficult to reverse Yu Qiu? Isn't it the same situation when I practiced the phoenix dance and practiced the qi technique?
