Lu Tianxing told Meng Chao that the human brain has about 100 billion nerve cells, and if they were arranged in a straight line, the length would be more than 1,000 kilometers.

It may seem amazing, but nerve cells are well-differentiated cells and cannot be regenerated.

Even if the transcendent has the power to penetrate the heavens and the earth, at most they use psionic energy to stimulate and repair some nerve cells.

Once a nerve cell dies completely, even the transcendent cannot regenerate it.

However, the extraordinary are very prone to the death of large numbers of brain nerve cells - such as the stirring of magnetic fields, overdrawing life, overloading the brain, and squeezing out the limit of computing power and deduction ability.

Or, like the Battle of King's Landing, you were psychologically attacked by a strange beast.

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

At worst, the mind is twisted, and they become lost, even monsters in human skin.

In light of this, it is necessary to come up with ways to temper and run the brain without harming the nerves of the brain cells.

His "Star Spirit Visualization Technique" is one of the strongest brain refining methods in Dragon City.

The general principle is to scan the structure of the psychic magnetic field in one's brain and the circuits of brain nerve currents through visualization, so as to find the most critical neuronal thinking nodes.

Subsequently, psionic energy was used to simulate the cranial nerve electrical circuit, and a new set of thinking circuits composed of purely psionic energy was built on top of the cerebral cortex.

It is equivalent to a carbon-based brain, equipped with a new set of virtual thinking and computing systems.

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

Because it is constructed of pure psionic energy, no matter how large and complex the amount of calculations is, it will not damage the real cranial nerves and brain cells, even if the overload calculation causes the virtual brain to collapse, at best it consumes some psionic energy, as long as you enter the deep meditation state again, it will take a few days to rebuild the virtual brain.

Once cultivated to the realm of Lu Tianxing, it is completely possible to use both oneself and one mind, with carbon-based brains and virtual brains running at the same time, and even carrying and running several virtual brains at the same time.

In the heat of battle, the virtual brain can also form the strongest barrier outside of the carbon-based brain.

Unless you are caught off guard and encounter a "doomsday-level", super monster that is good at psychic attacks, such as a "demon god" like the Abyss Demon Eye.

A nightmare beast like an ordinary Sky Splitting Demon Eye would not be able to shake Lu Tianxing's mind at all.

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

I believe that it can help Meng Chao go further on the road of transcendence, and one day, break through the legendary realm of gods.

"I have studied the 'Limit Flow' of your Agricultural University Martial Arts Department, and I know that you have opened up all the hundreds of branch veins distributed around your brain, and I believe that there is not much obstacle for you to cultivate the Star Spirit Visualization Technique."

Lu Tianxingdao, "The first step is to imagine that 100 billion nerve cells in the brain are 100 billion shining stars, and your brain domain is a unique small universe comparable to the sea of stars......"

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

"Star Spirit Visualization", this is a peerless supernatural power that he couldn't access as a "third-rate master" in his previous life.

Unconsciously, his cranial nerve cells echoed with the virtual stars constructed by Lu Tianxing, and gradually shone with brilliant brilliance, really 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 that crossed time and space, as well as the alien fire in the depths of the soul, gradually merged together.

I don't know how long it took.

Meng Chao slowly opened his eyes and found himself 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, and said incredulously: "Meng Chao, what's the situation, how do you feel that you have only sat down for three seconds, and before you have time to say hello to Dr. Lu, the temperament of the whole person has undergone earth-shaking changes, especially your eyes......"

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

"Yes, I don't know how to thank you except for Star Spirit Visualization."

Lu Tianxing said lightly, "My personal life and death are nothing, but the 101 project has just progressed to the most critical stage, and most of the members of the project team are gathered in the King's Landing Hotel, that night, it is really dangerous, if the project team is wiped out, our hope of returning to the earth will be completely shattered, in this case, the future of Dragon City, I am afraid it will be very bleak." ”

Since Dr. Lu took the initiative to talk about the topic of crossing.

Meng Chao couldn't restrain his curiosity.

He was most concerned about two issues.

First, can Dragon City really travel back to Earth, or is there really any hope that the space tunnel between the Otherworld and the Earth will be opened?

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

He knew that under the Transcendent Tower, there was the territory of the "Relic Research Institute", and many highly classified cutting-edge projects were carried out inside.

The reason why many God Realm powerhouses do not often participate in the hunting of monsters is that they devote all their energy and even their entire lives to the study of the primeval 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 you can completely understand the mystery of the ancient ruins, not to mention the monster mountain range, even the entire other world, is at your fingertips.

Although among the memory fragments of the previous life, it took the people of Dragon City for decades to fully understand the mystery of the ancient ruins.

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

And at noon on the day he was reborn.

A laboratory in the depths of the Transcendent Tower also had an unprecedented explosion.

Is "rebirth" the same as "traversal", verifiable, repeatable, and controllable?

If so, what does it mean for human civilization?

Although Lu Tianxing is a crossing expert, not a rebirth expert, he may be able to collect some useful information from him?

"Dr. Lu, you said that Project 101 has progressed to the most critical stage, is it not long before we can return to Earth?"

Thinking of this, Meng Chao said excitedly.

If so, the future will be completely changed.

Zhao Feixian, who was next to him, was also breathing heavily.

The people of Longcheng, who have been adrift for half a century, are just like wanderers who have left their hometowns, who is not eager to see the blue planet with their own eyes?

Facing the expectant eyes of the two, Lu Tianxing pondered for a moment and said: "The research and development of controllable crossing technology is indeed expected to make breakthroughs, but if we really want to return to Earth, we still have a lot of preliminary preparations to do." ”

Meng Chao and Zhao Feixian glanced at each other, and they didn't understand what Lu Tianxing meant.

"The simplest truth, we all know that the earth is a world without psychic energy, highly dependent on machinery, chips, chemical energy and atomic energy to build and defend civilization, but the aura of the other world is too abundant, and extremely unstable, too complex and sophisticated machinery, it is easy to damage here, which means that compared to the transcendent who has adapted to the living environment of the other world, the combat effectiveness of the earthlings may not be very strong."

Lu Tianxing explained, "We haven't sketched the whole picture of the Otherworld yet—we don't know if there is a more terrifying existence than monsters in the depths of the Otherworld, and we don't know where the primeval civilization that left the ancient ruins and got us here has gone, and we don't even know what kind of impact it will have on the basic laws and physical laws of the two worlds once the tunnel between the otherworld and the earth is opened."

"Without knowing anything, rashly opening up a space channel may lead to viruses, spores, monsters and even gods and demons from other worlds escaping to the earth.

"If it is the zombie virus in film and television dramas that can only be transmitted through saliva and blood, of course the compatriots on Earth can deal with it.

"But the new zombie virus has been able to spread through dozens of methods such as droplets and mosquitoes, and it can barely resist it by relying on the upgraded immune system evolved by the people of Longcheng in half a century - and the immune system of the earth's compatriots, without such an 'upgrade', the moment the tunnel was opened, tens of millions of earth's compatriots were tragically infected, and such a nightmare is not impossible.

"Not to mention the 'Blood Pattern Flower', a terrifying creature that can spread to the entire earth through snakes, insects, rats and ants, once they are completely out of control on the earth, the consequences are unimaginable, and we are very likely to become sinners for the ages who destroy the human civilization on the earth!"

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

Especially Meng Chao, who had seen the terrifying gods and demons of the other world in the memory fragments of his previous life, was even more cold in a cold sweat.

Indeed, you can't just think about Dragon City and not the whole earth.

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

The passage between the two realms cannot be opened casually.

"Dr. Lu, if you say that, before we figure out the truth of the other world, the return to Earth is far away, so we have invested so many resources in the research and development of time-traveling technology, isn't it...... Can't distant water save a near fire? Meng Chao asked half rejoicing, half disappointed.

"It's a simple question."

Lu Tianxing smiled slightly, and said unhurriedly, "The full name of the 101 project is the 'Controllable Crossing Technology R&D Project', not the 'Return to Earth' project, let your imagination fly, as long as we develop relevant technologies, who said that we can only travel to the Earth?" ”
