Yu Xiaoyue is responsible for the garrison work, Lightning is responsible for the people's livelihood work, and the research and development force of Binhai City is responsible for Xu Yongzhi's father and daughter.

In this world, the vast majority of human forces have given up their technological power, or only as an auxiliary. In the battle against the demon clan, the effectiveness of modern technological weapons is poor.

In the early days of the revival of the aura demons, the human world used to use modern thermal weapons on a large scale to fight. But live-ammunition weapons don't work against many demons at all.

Human artillery can blast zombies and skeletons into powder, but disembodied spirits can easily break through the fire blockade and wipe out the human army in the fortifications.

Only cultivators with spiritual power can actually kill them.

And because of the conflict of ideas, practitioners actually don't like science.

Over time, many places have abandoned technology in favor of strengthening the power of practitioners. After all, it is not known how long it will take for scientists to develop weapons against the demon clan, but one more cultivator will have more real strength.

In this case, a large number of scientists lose their jobs and become precarious civilians. Binhai City became the last refuge for scientists in the Central Plains, and Yu Xiaoyue accepted them under difficult conditions and ensured their lives and safety.

Professor Xu Yongzhi led the scientists to make use of the power of science and technology as much as possible. After several years of hard work, they overcame the difficulties of aura absorption, storage, transportation, focusing, transformation, and release, and developed the first pulse-type aura diffusion cannon.

In the last defensive battle, the aura diffusion cannon showed its might, seriously injuring the demon general with one shot. This is an effect that has not been achieved with nuclear bombs in the past.

It's a pity that there is only one at present, and the magic crystal ball of the aura diffusion cannon will have to be replaced after a few shots, so the actual combat significance is not great. The Binhai Academy of Occult Sciences is currently trying to change its thinking and create other spiritual weapons.

"Why do you think it's meaningless?" said Sun Da, who almost cried with his head in his arms, "how did you manage to combine science and metaphysics?"

Sun Xiang himself is a pretty good scholar of natural sciences, and he has won many doctorate titles in natural sciences during his long years. It was impossible for him not to have thought about combining technology and cultivation, but after thinking about it several times, he finally found that this path was not working.

The reason is very simple, all the manipulation of aura needs the support of divine thoughts, and divine thoughts cannot be simulated with technology.

Not only is it not simulable, but it is not even compatible in principle.

Sun Xiang's exercises are majoring in divine thoughts, and he knows a lot about it. After all, Shennian is a kind of arithmetic, but Shennian arithmetic is completely different from algebraic calculations in mathematics.

Mathematical calculations are the cause to determine the effect. For example, if one plus one is determined, then the result can be determined to be two. But when the result is two, it is not certain that the cause is one plus one, because it is also possible that the cause is three minus one.

In metaphysics, the divine mind is the exact opposite, and it is the cause of the result. The result is that when two are determined, the cause is one plus one. But one plus one doesn't necessarily equal two, it can also equal three equals four, or everything.

This is one of the cornerstone principles of metaphysical research, called "the effect must be the same cause", and this theory was put forward and perfected by the Venerable Gui Yuan of the previous era.

Mathematical calculation is the foundation of all science and technology, and divine arithmetic is the foundation of all metaphysics.

Sun Xiang found it difficult to understand how Xu Yongzhi fused metaphysics and science together. How did Marina solve this essential contradiction?

"Actually, I don't understand either, I'm just holding a ready-made formula. As for how the formula came about, you have to ask her. Professor Xu honestly admits his ignorance.

Everyone's eyes looked at Xu Yishan.

Sun Xiang has a big mouth.

"No, it won't. ”

Xu Yishan pretended to cough, and took out a pair of flat glasses from her pocket to put on herself.

"Actually, this is not my work alone, I just picked up the research results of Taishi Niang. ”

She explained.

Shortly after the opening of the Binhai Academy of Metasciences, Professor Xu was trapped by the major problem of the incompatibility of scientific metaphysics. Essentially, Reiki is a type of energy, no different from electricity or nuclear energy.

However, the operation of Reiki is completely metaphysical and cannot be carried out by scientific means. After months of research, all the scientists finally came to the conclusion that metaphysics and science are different mathematical foundations and are incompatible.

Just when everyone was most desperate, Xu Yishan stood up. Because she found Taishi Niang's last paper in Sun Yulan's manuscript.

When Sun Yulan was young, she completed a huge series of papers entitled "The Geometric Properties of the Extradimensional Universe", and it was on the basis of this paper that the metallic hydrogen catalyst at room temperature was discovered.

But there is actually a major error in this paper, and Sun Yulan's argument in calculating the eleven-dimensional space is flawed, and she has been thinking about this problem all her life.

Until a few days before her death, in a discussion with Sun Xiang. In those narratives about origin, life and death, and the way of heaven, Sun Yulan was greatly inspired. She completed her last research, the Chaos Domain, from her hospital bed.

"Tai Shi Niang's last research has gone beyond the limitations of human cognition, and I have only understood a small part of it. I built on her work to complete the commutation algorithm for the chaotic domain. ”

Xu Yishan recalled the shock when she saw Sun Yulan's Chaos Domain paper, and she couldn't calm down even now. She had seen the unfinished vortex formula in Taishi Niang's manuscript before, and she was a little contemptuous of Sun Yulan.

But this last paper hit the little Lori so badly that she didn't want it.

"The Chaos Domain denies the existence of cause and effect, and is therefore backward compatible with scientific and metaphysical calculations. Here's how it works......"

Xu Yishan was about to explain further, but Sun Xiang suddenly stretched out a finger and put it on her lips, with an extremely serious expression.

Everyone was baffled by Sun Xiang's move. Sun Xiang didn't explain, he pointed his finger at Xu Yishan's head, and then raised his finger and pointed to the sky.

Xu Yishan's eyes were first puzzled, then frightened, and finally seemed to understand something, she lowered her head.

"I know, I'll never say it, only I know the principle. ”

Sun Xiang nodded with satisfaction and said to everyone: "Since the Binhai Academy of Xuanke has solved the fundamental problem of the conversion of divine arithmetic and algebra, then I believe that we will have a bright future." Professor Xu, continue to research, this path is the right path. ”

"But there's a point. He raised his finger and warned everyone present, "The algorithm formula provided by Xu Yishan, please use it directly, and it is strictly forbidden to ask her about the derivation process and principle." ”

The momentum of Sun Da's head was very dangerous, and everyone present was a little shocked.

"Anyway, I don't understand if I ask, so let's just assume that there is no such thing. Lu Ning saw that the atmosphere was more serious, and snorted. Everyone nodded yes.

Sun Xiang sighed, thinking that fortunately no one understood, and if he understood, something big would happen.

He didn't see his daughter's final paper, but according to Xu Yishan, Sun Yulan finally completed the study of the properties of the eleventh-dimensional universe.

The eleventh dimension of the universe is the origin, and the law of operation of the origin has another name in metaphysics.
