Long Yuandong asked the students to find whiteboards and carbon pens from the multi-purpose hall to facilitate Jiang Mantian's explanation.

The teachers and students who surrounded him looked at Jiang Mantian with anticipation.

Outside the window, zombies came out from all corners and gathered outside the gymnasium door. Inside the window, people were on guard and guarded.

However, no one knows how long human beings can hold on, how long they can hold on, and where they will go from here.

At this moment, everyone is desperate to know what exactly will happen in the future.

"In ancient Chinese philosophy, it is believed that people have three souls and seven spirits.

The three souls are the heavenly soul, the earth soul, and the life soul, and the seven souls are the heavenly chong, the spiritual wisdom, the center, the qi, the force, the essence, and the ying. ”

Jiang Mantian wrote the word soul on the whiteboard with a pen and circled it twice:

"The ancients divided the soul and the spirit very carefully, some of which are indeed pointed, and some of which are just for the sake of making up the number, and are not credible.

Based on my superficial understanding of the doctrine of the Three Souls and Seven Souls, the 'Three Souls' exist in the brain and are in charge of intelligence, emotions and life.

The 'Seven Spirits' exist in the body and govern strength, agility, movement, and coordination, and for the sake of simplicity, we collectively refer to the 'Seven Spirits' as 'Physique'.

What is the relationship between the 'soul' and the 'body'? It should be that the two have their own jurisdiction and are related to each other.

For example, the human body breathes all the time, the pulse beats all the time, even when the brain is resting during sleep, indicating that the body's breathing and blood flow are controlled by the body, not the soul.

However, although the 'Zhi Soul' does not directly control the breathing and pulse, it can affect or stop the breathing and pulse, such as ourselves, and we can consciously hold our breath without breathing, indicating that the 'Zhi Soul' also plays an important role in life activities.

To borrow the concept of yin and yang, the 'body' is yin and the 'wisdom soul' is yang, and the two are mutually reinforcing, transforming and complementing each other. Generally speaking, if the body is strong, the soul will not be too weak. But if the body is too strong, the mind may not be fully developed, and vice versa. ”

Jiang Mantian paused, his eyes swept to the students around him, and found that most of them listened with relish, and there was no dazed look, and he couldn't help but secretly praise in his heart, worthy of being a student of the National University, his understanding was really extraordinary.

"Under the new geomagnetic conditions, man's 'intellectual soul' and 'physique' have been fully liberated and developed rapidly, and theoretically, there will be at least four evolutionary directions. ”

"The first is the concentrated development of the 'physique', and eventually abilities such as body madness and bloodline totems appear, called berserkers, totem gods, etc. This type of evolution, there is also a heresy, they can achieve some kind of special communication with zombies, and even be able to control zombies, there is a special term, called 'exorcists'. The principle is that although the zombie does not have a 'wisdom soul', the 'physique' still exists, and if you encounter someone with a stronger 'physique', you will naturally involuntarily obey its orders. This is the case with Zhang Ziwu's evolution. ”

"The second is the prominent development of the 'wisdom soul', which is similar to the ability to control beasts and summon pets, this kind of person is called 'summoner', the principle is that the spiritual power is extremely strong, and it can communicate with other creatures such as beasts. Among such evolutionary people, there are also outliers who can communicate with pure spirits, called ghost mages or necromancers, superstitionally speaking, people who can talk to ghosts. ”

"The third type is still the 'wisdom soul' that is prominently developed, but in a different direction than the second one. This kind of person is born with a particularly strong sense of direction and a particularly keen sense of magnetic poles. In the new geomagnetic space, its sense of direction has evolved into the ability to sense the stars, and when it evolves to a certain extent, it can draw the stars and use the power of the universe for its own use, which is called the 'Star Master'. ”

"The fourth is that the 'mind' and 'body' are fully developed at the same time, and the situation is the most complicated. As you can see, some of our students have evolved abilities such as Ice Picks, Iron Spikes, Fireworks, Earth Shields, Wooden Fences, Shadows, and so on, all of which fall into the fourth category. ”

"Everyone must ask, why do so many strange phenomena occur when the soul and body evolve together? Are there any laws to follow for all the phenomena?" Jiang Mantian was afraid that everyone would be bored to listen to, and after explaining the general principle, he threw out a new question to guide everyone to think further.

However, with such a difficult and professional question, it is naturally impossible for anyone to come up with an answer in a short period of time.

So he paused for a moment and explained:

"In life, we are born with the ability to communicate with nature. In the past, most of this ability of human beings was imprisoned, but under the new magnetic field space, these abilities are gradually liberated. From this, we think that since it is a communication with nature, then what nature has, of course, has evolved capabilities.

Therefore, at the beginning, we used the four elements of Western Regions philosophy 'earth, water, fire, and wind' as a model to verify it, and found that the idea was correct, but the direction of evolution was complicated, and it was not limited to this. So I used the five elements of 'gold, wood, water, fire, and earth' to distinguish it, but I still found that it could not be summarized all. After a lot of research, he finally summed up the concept of the nine houses, which are light, darkness, time, space, wind, thunder, wisdom, emotion, and life.

The Five Elements and Nine Palaces basically cover all the elemental attribute types that make up nature, and all the phenomena of supernatural abilities can be summarized in it. ”

Jiang Mantian paused slightly, and sighed: "I have devoted myself to studying the evolution of the human brain, but it is difficult to make arguments, there is no way to verify it, and the progress has been slow. In a few years, even guessing, half-estimating and half-calculating, in the end, I only understood a few superficial concepts. In fact, I don't know how human beings will evolve according to these laws or not. Judging from today's situation, it basically confirms my inference. ”

"Isn't this the awakening of the martial spirit?"

Several classmates exchanged heads: "There are many online novels, such twin martial souls, ontological martial souls, extreme martial souls, primeval xenomorphs, berserker warriors, priests or something, I didn't expect it to really exist!"

Jiang Mantian's eyes lit up: "Just now, a classmate mentioned martial spirit, I think this is a very condensed concept. The physique is martial arts, and the wisdom soul is called the soul, which together is called the martial soul, which is both concise and vivid. ”

"Since everyone has a soul and a physique, that is, everyone has a martial soul, and everyone has a chance to evolve?"

"Then why do some people evolve? Some people don't? If evolution varies from person to person, where is the source of the difference?"

"If it is the advancement of the strong body, why do I see that among the people who have evolved, some of the bodies are not strong, and among the people who have not evolved, some of the bodies are not weak?

If there are more than 10,000 people with advanced brains, there will not be only a few people with developed brains, right? Among those who have not evolved, I think there are many very smart people.

And if the people who participated in the battle advanced, then why did so many people participate in the battle, and only a small part of them evolve, and among the people who did not participate in the battle, there are also people who evolve?"
