Fang Lin left with a large number of medical books, including "Barefoot Doctor Manual", "Authentic Surgery", "Principles of Anatomy" and other medical works.

This is different from other disciplines. In other disciplines, you can basically master the corresponding knowledge by learning the corresponding level, but medicine is different. Most of the knowledge can be browsed after passing the "introduction". The real test is more about experience and technology.

So after 25 Medicine, Feng Xue can almost find most mainstream medical works, because in medicine, mainstream means basics.

Compared with those secret recipes and unique skills that require high skills, these things are undoubtedly what Fang Lin needs the most.

Fang Lin looked through these textbooks and felt like he had a treasure. After thanking him, he disappeared into the distance with his army of living dead. At this time, Feng Xue, who had not slept much all night, was very excited and immediately attracted Xu Fu and asked him to send the three girls to the county government. He went into the study and took out the booklet that Fang Lin gave him.

He only had a dozen pages of booklets, not research notes, but textbooks that were specially copied and handed over to his disciples, which made Feng Xue convinced that this must have been what Fang Lin planned to hand over to him from the beginning.

But he didn't care about this, and started to read it carefully from the first page.

The one recorded at the forefront is not the Qi and Blood spell that Fang Lin learned first, but some statements about the theory of essence and energy.

Fang Lin believes that this qi and blood are the essence of all things, representing vitality and the basis for the existence of all living beings. Corresponding to the physical body, humans will age and die because the efficiency of converting essence through eating is not as good as maintaining their own consumption.

Fang Lin has been operating for more than 200 years by absorbing qi and blood, and seems to have complied with his theory.

Living in the mythical world, Feng Xue does not intend to use her modern earthly common sense to explain everything. Even if aging is due to the limit of cell self-replication, then what is the limit determined by this limit? Perhaps replenishing qi and blood increases the lifespan of cells and increases the limit of cell division?

And in a sense, this theory of "eating is to convert the essence in food into essence that humans can absorb" is quite similar to the legendary "refining essence into qi".

But in this way, the reason why those demons and ghosts, innate powers, can live forever is because they can directly swallow the spiritual energy between heaven and earth to replenish their own essence?

"It's really interesting." Feng Xue sighed in her heart. Fang Lin is worthy of being a top student. With a simple healing spell, he can actually develop a whole system! Unfortunately, there is no good enough basic education, otherwise it would be even more terrifying.

"I would have kept him if I had known it. Anyway, I don't have many people in my farm." Feng Xue muttered to herself, but she knew that it was impossible. It would be fine if he had not notified Wu Zhu, but the genuine monk was about to arrive, so he would definitely not stay in Sheyang County.

Putting aside the regrets in my heart, Feng Xue continued to read.

After the basic theory, there are explanations of several runes.

Runes are not complicated, but they don’t look so easy to remember. What makes Feng Xue the most helpless is that it cannot activate the plug-in of [Language 100], which means that these runes are not texts with the meaning of "language".

"So, these runes are actually small trumpet array diagrams that look like text?" Feng Xue had a slight understanding in her heart, but he did not rush to record the so-called runes, but read the annotations of the runes first.

According to Fang Lin's records, these three runes are the most important part of the entire Qi and Blood spell system. The first one is used to extract Qi and Blood, the second one is used to guide Qi and Blood, and the third one is used to release Qi and Blood. All his current Qi and Blood spells are based on these three runes, combined with other symbols on the Ancient Scroll of the Beast Skin, and the disgust that has been experimented over the years.

"The original animal skin scroll should also be printed." Feng Xue thought so, but shook her head again. She was not satisfied with greed and swallowing an elephant. She had been studying for two hundred years, but wasn't she satisfied with the research results she had obtained directly?

Let go of greed and continue to flip through. The spell worlds based on three runes gradually appeared in front of Feng Xue-

From the simplest way to transfer qi and blood to healing injuries, to distributing qi and blood to improving life span.

From external blood strips that store qi and blood, to the spirit trapping technique that uses qi and blood to restrain the soul.

From coma that cuts off the flow of qi and blood, to puppet technique that controls the human body by manipulating the flow of qi and blood.

The complete R&D lines made Feng Xue fascinated. Although he did not have any wonderful skills structure, the steady and slowly advancing research process made Feng Xue feel a sense of order.

"This Fang Lin is really not simple..." Feng Xue finished reading the resurrection technique on the last page, turned the page to the first page again, and began to carefully remember the runes on it.

In fact, there are only a few strokes of the three basic runes, otherwise Fang Lin would not have finished drawing them before he died. However, I think this thing was a slight mistake and a thousand mistakes. Feng Xue had to cheer up and remember every angle and every turn as much as possible.

The sky outside gradually became brighter, but Feng Xue was still in the excitement of learning. There were less than ten spells in the original booklet, but this research idea made Feng Xue have no doubt that she could continue to develop along this path.

To put it bluntly, extracting-guiding-release of these three runes is almost equivalent to a complete circulation system, just like a power station, providing a continuous stream of energy. Feng Xue now only needs to think about how to build an "electrical appliance" and use this energy.

Moreover, even if Feng Xue doesn't study it further, just the spells above have already made Feng Xue very useful-

Coma and puppet technique provided him with certain self-protection ability. Although it was probably only for mortals, at least there was no need to worry about guards going against it. The technique of extending lifespan by absorbing qi and blood has solved the lifespan problem that Feng Xue has always been worried about. In addition, what Feng Xue likes the most is the spell of "qi and blood body-building".

Although it is called Qi and Blood Body, this spell is not the kind of martial arts that cannot be invulnerable to swords and guns. It is a technique studied by Fang Lin in the early days to solve the problem of muscle atrophy of the living dead. It is considered a transitional version of puppet technique.

But in Feng Xue's opinion, this technique of using qi and blood to guide muscle movement is a traitor who is copying books every day and has no time to exercise. It is simply a traitor of "you can become a muscular man without having to be very troublesome and tired"!

"But you also need to cooperate with fitness knowledge... Well, go to sports medicine to find it. At least the distribution of red and white muscles must be reasonable... With this, you can even develop a set of spells for training, so that soldiers can save more physical training time to train skills..."
