Lu Tianxing told Meng Chao that the human brain has about 100 billion nerve cells. If they were arranged in a straight line, the length would be more than a thousand kilometers.

It seems very surprising, but nerve cells are highly differentiated cells and cannot be regenerated.

Even if an extraordinary person has the power to reach heaven and earth, he or she can only use spiritual energy to stimulate and repair some nerve cells.

Once a nerve cell dies completely, even an extraordinary person cannot regenerate it.

However, extraordinary people are very likely to encounter situations where large areas of brain nerve cells die - such as stimulating magnetic fields, overdrawing life, overloading the brain, and squeezing out the ultimate computing power and deduction ability.

Or, like the battle at the King's Landing Hotel, you were mentally attacked by alien beasts.

Once a large number of brain nerve cells die, it will damage combat effectiveness, research ability and cultivation potential.

At worst, the mind becomes distorted, becomes obsessed, and becomes a lost person, or even a monster in human skin.

In view of this, it is necessary to find a way to temper and operate the brain without damaging brain cells and nerves.

His "Star Spirit Visualization Technique" is one of the most powerful brain-tempering methods in Dragon City.

The general principle is to scan the spiritual magnetic force field structure in your brain and the circuits of brain nerve currents through visualization to find the most critical neuron thinking nodes.

Then, psionic energy was used to simulate the brain nerve current circuit, and a new set of thinking circuits composed purely of psionic energy was built on the cerebral cortex.

It is equivalent to a carbon-based brain equipped with a brand new virtual thinking and computing system.

Once the "virtual brain" is formed, many non-fuzzy logic and large-scale calculation problems, such as calculating the trajectory of thermal weapons, deducing hundreds of attack modes of monsters, etc., can be carried out in the virtual brain.

Because it is constructed of pure spiritual energy, no matter how large and complex the calculation is, it will not damage the real cranial nerves and brain cells. Even if the calculation is overloaded to the point where the virtual brain collapses, it will only consume some spiritual energy. As long as it enters the depth again

In a meditative state, it takes a few days to reconstruct the virtual brain.

Once you have cultivated to the level of Lu Tianxing, you can do two things at once. The carbon-based brain and the virtual brain can run at the same time, and you can even carry and run several virtual brains at the same time.

In a fierce battle, the virtual brain can also form the strongest barrier besides the carbon-based brain.

Unless you are caught off guard and encounter "doomsday-level" super monsters that are good at psychic attacks, such as "demon gods" like the Abyss Demonic Eye.

Ordinary nightmare beasts such as the Sky-Splitting Demonic Eye are simply impossible to shake Lu Tianxing's mind.

As long as the brain's energy consumption and heat dissipation problems are solved, "Star Spirit Visualization Technique" does not have much side effects.

I believe it can help Meng Chao take a further step on the road to transcendence and one day break through the legendary realm of gods.

"I have studied the 'Extreme Flow' of your Agricultural University Martial Arts Department and know that you have opened up hundreds of branches distributed around the brain. I believe that for you, practicing "Star Spirit Visualization Technique" is not a big deal.

obstacles.”

Lu Tianxing said, "The first step is to imagine that the 100 billion nerve cells in your brain are like 100 billion shining stars. Your brain is a unique small universe comparable to the sea of ​​stars..."

Meng Chao was deeply attracted by Lu Tianxing's words.

"Star Spirit Visualization Technique" is a peerless magical power that he, as a "third-rate master" in his previous life, had no access to.

Unknowingly, his brain nerve cells echoed the virtual stars constructed by Lu Tianxing, gradually shining brightly, and slowly rotating like a brilliant sea of ​​stars.

Meng Chao was completely immersed in the vastness, majesty and mystery of the sea of ​​stars.

Time and space seem to have lost their meaning.

The two souls spanning time and space, and the strange fire deep in the soul, gradually merged together.

I do not know how long it has been.

Meng Chao slowly opened his eyes and found that he was still sitting on the sofa in the corner of the ward.

Taking a deep breath, he glanced at Zhao Feixian who was sitting on the sofa next to him, but Zhao Feixian trembled all over and said in disbelief: "Meng Chao, what's going on? Why do you feel that you only sat down for three seconds and didn't even have time to say hello to Dr. Lu?

A person's temperament has undergone earth-shaking changes, especially your eyes..."

Meng Chao smiled slightly and said sincerely to the old man on the hospital bed: "Thank you, Dr. Lu, for your advice."

"That's right. Apart from the "Star Spirit Visualization Technique", I don't know how to thank you."

Lu Tianxing said lightly, "My personal life and death don't matter, but the 101 project has just progressed to the most critical stage, and most of the members of the project team gathered at the Junlin Hotel. That night, it was really...

It's dangerous. If the entire project team is wiped out, our hope of returning to Earth will be completely shattered. In this case, the future of Dragon City will probably be very bleak."

Since Dr. Lu took the initiative to talk about time travel.

Meng Chao couldn't restrain his curiosity.

There are two issues that concern him most.

First, can Dragon City really travel back to the earth? In other words, is there really any hope of opening up the space tunnel between another world and the earth?

Second, what exactly is the so-called "rebirth"?

He knew that under the Extraordinary Tower was the territory of the "Relics Research Institute", where many highly confidential and cutting-edge projects were being carried out.

The reason why many powerful gods do not often participate in hunting monsters is because they devote all their energy and even their entire lives to the study of ancient ruins.

According to them, killing monsters is to defend the present of Dragon City, but studying the ancient ruins is to achieve the future of Dragon City. If the secrets of the ancient ruins can be thoroughly understood, let alone the monster mountain range, even the entire alien world will be at your fingertips.

of.

Although the people of Longcheng spent decades in the memory fragments of their previous life, they still could not fully understand the mystery of the ancient ruins.

But Meng Chao remembered that when the end of his previous life came, it was indeed a beam of strange fire from the depths of the Extraordinary Tower and the ancient ruins that sent his soul back to the "present".

And at noon when he was reborn.

An unprecedented explosion also occurred in a laboratory deep in the Extraordinary Tower.

Could it be that "rebirth" and "time travel" are both verifiable, repeatable, and controllable?

If this is true, what does it mean for human civilization?

Although Lu Tianxing is an expert in time travel, not rebirth, perhaps we can collect some useful information from him by making some insinuations?

"Dr. Lu, you said that Project 101 has progressed to the most critical stage. Could it be that it won't be long before we can return to Earth?"

Thinking of this, Meng Chao said excitedly.

If so, the future will be completely changed.

Next to him, Zhao Feixian was breathing heavily.

The people of Longcheng who have been wandering for half a century are like wanderers thousands of miles away from their hometown. Who doesn't long to see the blue planet with his own eyes?

Facing the expectant looks of the two people, Lu Tianxing pondered for a moment and said: "There is indeed hope for breakthrough progress in the research and development of controllable time travel technology, but if we really want to return to Earth, we still have a lot of preliminary preparation work to do.

Do."

Meng Chao and Zhao Feixian looked at each other, neither understanding what Lu Tianxing meant.

"The simplest truth is that we all know that the earth is a world without spiritual energy. It relies heavily on machinery, chips, chemical energy and atomic energy to build and defend civilization. However, the spiritual energy in other worlds is too abundant, extremely unstable, and too complicated.

Precision machinery is easily damaged here, which means that compared to extraordinary beings who have adapted to the living environment of other worlds, the combat effectiveness of earthlings may not be very strong."

Lu Tianxing explained, "We haven't yet sketched out the whole picture of the other world - we don't know whether there are existences more terrifying than monsters in the depths of the other world, nor do we know what ancient ruins have left us behind.

Where did the ancient civilization that came here go? We don’t even know what impact it will have on the basic laws and physical laws of the two worlds once the tunnel between the other world and the earth is opened.

"Rushly opening space channels without knowing anything about them may cause viruses, spores, monsters and even gods and demons from other worlds to escape to the earth.

"If it were the kind of zombie virus in movies and TV shows that can only be spread through saliva and blood, of course our compatriots on earth can deal with it.

"But the new zombie virus can already be spread through dozens of methods such as droplets and mosquitoes. It can only be resisted by the upgraded immune system that the people of Longcheng have evolved in half a century - and the immune systems of compatriots on the earth cannot.

After such an 'upgrade', the moment the tunnel was opened, tens of millions of fellow citizens on Earth were tragically infected. Such a nightmare is not impossible to happen.

"Not to mention the terrifying creatures like the 'Blood-striped Flower' that can spread to the entire earth through snakes, insects, rats and ants. Once they get completely out of control on the earth, the consequences will be disastrous. We are very likely to become the annihilation of human civilization on the earth.

Sinner!"

Lu Tianxing's words made Meng Chao and Zhao Feixian tremble suddenly.

Especially Meng Chao, who had seen with his own eyes the horror of gods and demons from other worlds in the memory fragments of his previous life, and was even breaking out in a cold sweat.

Indeed, we cannot only consider Dragon City and not the entire earth.

Judging from the scenes in the doomsday nightmare, it is comparable to a full-scale nuclear war on the earth. Even if the power of the entire earth is gathered, it may not be an opponent of the gods and demons from other worlds.

The passage between the two realms cannot be opened casually.

"Dr. Lu, if you put it this way, before you figure out the truth about the other world, returning to Earth is far away. So if we invest so many resources to develop time travel technology, isn't it... that distant water can't save nearby fire?" Meng Chao was half-rejoiced.

, asked half disappointed.

"This question is very simple."

Lu Tianxing smiled slightly and said calmly, "The full name of Project 101 is the 'Controllable Time Travel Technology Research and Development Project', not the 'Return to Earth' project. Let your imagination run wild, as long as we develop the relevant technology
