Today happened to be Chen Yihai's turn to rest, so after Chen Yihai came back from morning exercise, he changed his clothes, ate a simple breakfast at a snack bar outside the community, and went straight to the Xinhua bookstore in the city center.

This Xinhua Bookstore is the largest bookstore in the city with the most complete range of books, which sells a variety of sporting goods and school supplies, as well as related books and audio-visual items.

Each floor of this Xinhua bookstore has an area of more than 500 square meters, and there are six floors up and down.

Generally speaking, people who have come out to work, during their rest time, either go out with their friends of the opposite sex, or seize the rare holiday at home to sleep with their heads covered.

Although there are also many girls who want to be with Chen Yihai, they are all skillfully rejected by Chen Yihai.

Chen Yihai feels that he is still young, and he has not yet been said to have a successful career, although the income is very high, but Chen Yihai has no plans to deal with the target at present.

Therefore, in the rare rest time, Chen Yihai's favorite places to visit are the second-hand book stalls and this Xinhua bookstore.

At present, although Chen Yihai does not dare to say everything about this Xinhua bookstore, he still knows clearly which place of which kind of books are placed on that floor.

After coming to the bookstore, Chen Yihai went straight to the third floor where various ancient and modern Chinese medicine classics were placed, and came to the bookshelf where the Chinese medicine classics were placed.

This thick "Dictionary of Traditional Chinese Medicine" includes almost all the Chinese medicinal materials found today, which is exactly what Chen Yihai needs most at present.

Last night, after Chen Yihai finished reading "Medicinal Properties" and "Four Hundred Flavors of Medicinal Properties", he compared the medicinal materials recorded in them with the various medicinal materials in the memories of Baiyundao people and found them.

Some of the medicinal herbs commonly used on the Celestial Star Continent are not available on the earth, and some of the medicinal herbs commonly used on the Earth are also not available on the Celestial Star Continent.

Although in terms of understanding of medicine and pharmacology, Chen Yihai dares to say second on the whole planet, and no one dares to say first, but the understanding of various Chinese medicinal materials on this planet is far inferior to those Chinese medicine masters who have been fighting with medicinal materials for a lifetime.

Today's Chen Yihai is confident that even if he does not rely on medicinal materials, he can treat most diseases by acupuncture, massage, cupping, massage, scraping and other means, but if he encounters some more serious diseases, without the assistance of medicine, it is not impossible to cure it by relying on these means alone, but it will consume a lot of true qi.

Today's earth aura is so thin, whether it is for a martial artist or a cultivator, the true qi is so precious, and it is easy not to be willing to let it be lost.

Chen Yihai is also the same, he doesn't want his true qi to be consumed like this, his current cultivation is only the great consummation of the qi refining period, and if he wants to enter the foundation building period, he has to purify the true qi that is not pure enough in his whole body to be pure enough, and finally let it turn into innate true qi, so that he can be regarded as a successful foundation building.

In order to enter the foundation building period, Chen Yihai needs to accumulate a large amount of true qi, and in order not to waste his true qi, Chen Yihai has to use other means to improve his treatment effect.

Sometimes it's okay to use medication instead of some true qi treatments, anyway, Chen Yihai won't be willing to waste his true qi until the last resort.

A thick and thousands of pages of "Dictionary of Traditional Chinese Medicine" was read by Chen Yihai in less than half an hour, and his contents were thoroughly understood.

This reading speed is really amazing, if others see it, they will definitely think that Chen Yihai is a mental illness, just playing with flip books.

After Chen Yihai finished reading the "Dictionary of Traditional Chinese Medicine", he couldn't help but shake his head, although this "Dictionary of Traditional Chinese Medicine" is known as the standard manual for the use of traditional Chinese medicine, but from Chen Yihai's point of view, the content in it is also full of errors and omissions.

For example, the picking season of some medicines is wrong, the method of preparation is wrong, the amount of medicine used is wrong, the definition of medicinal properties is inaccurate or even wrong, and some toxic drugs are prohibited or the dosage is strictly limited, etc., this series of mistakes down, according to this "Chinese Medicine Dictionary" to treat diseases, not to mention the treatment of diseases and save people, it is not bad to eat people badly.

No wonder, Chen Yihai saw some TCM practitioners complaining about this "TCM Codex" on the Internet, and it is no wonder that those patients who have been treated by TCM complain that TCM treatment is ineffective.

After putting this "Dictionary of Traditional Chinese Medicine" away, Chen Yihai had to honestly pick up the oldest monograph on traditional Chinese medicine, "Shennong's Materia Medica", and read it.

Subsequently, dozens of monographs on traditional Chinese medicine, such as "Commentary on the Classic of Materia Medica", "New Revision of Materia Medica", "Compendium of Materia Medica", "Seeking Truth in Materia Medica", etc., were read by Chen Yihai in one morning.

Chen Yihai has basically thoroughly understood the efficacy, medicinal properties, attribution, picking, processing, compatibility, taboos, etc. of tens of thousands of drugs recorded in these drug monographs, and his attainments in drugs are no less than those masters of traditional Chinese medicine who have dealt with medicinal materials all their lives.

In addition, Chen Yihai also wrote down countless prescriptions, home remedies, test prescriptions, and treatment methods, and the harvest is not small.

After putting the last drug book back in its place, Chen Yihai suddenly felt very hungry, he was so involved just now that he almost forgot about his hunger, and took out his mobile phone to see that it was already more than one o'clock in the afternoon.

Chen Yihai plans to go out first to find a place to fill his stomach, and then come back in the afternoon to read all the medical works of the past medical masters, maybe the experience of these medical masters is not an important thing for Chen Yihai, who has the memory of Da Luo Jinxian, it can be said that it is dispensable.

However, ancient medical scholars were very cautious about writing books, and almost only after their later years would they summarize their life's medical insights and medical experience into books, so those ancient medical classics are still very valuable for reference.

Like those medical masters now, they can publish a medical work casually, but in fact, they are used to make a name for themselves and earn manuscript fees, and the gold content is really not very high.

It's no wonder that Chen Yihai saw that the content of the medical works he had collected before was full of errors and omissions, and his unique insights only accounted for a small part, and most of the content was plagiarized from each other, and the number of words was charged to earn manuscript fees.

Although Chen Yihai was hiding in a corner and no one was in the process of flipping the book, trying to avoid letting people see the scene of his crazy flipping books, he was still seen by a young girl with an unusually beautiful appearance wearing the work clothes of a bookstore staff.

After graduating from university, Zhao Xinyi did not work in the company opened by her family, but came to this bookstore to become a book manager through her family connections.

Today is Zhao Xinyi's first day at work, and when she was on patrol, she passed behind Chen Yihai seven or eight times, and every time she found that this young man kept turning books.

Zhao Xinyi couldn't help but be curious about this handsome young guy who might be neurotic!
