At the end of the underground square, there is a huge monitoring room hanging high. The leading teachers from all the high schools in Hulin District are gathered here to see clearly the commotion of the students.

"The quality of our graduates from Hulin District this year is quite good, and their fighting spirit is very high!"

The surveillance cameras followed Ning Xuese and Yan Feirou to the Nine Chinese Square Formation, and captured the conflict between Meng Chao and Jin Zhanpeng clearly.

Many of the city's top students had just suffered a terrible loss in Jianshe Middle School, which made the leading teacher feel bad.

Now seeing Jianzhong students failing in front of the district key points, the leading teachers at the city key points couldn't help but smile.

"What's this student's name, Meng Chao? We'll pay close attention to it later." They were discussing quietly, no, quite loudly.

The leading teacher of Jianshe Middle School, whose face was so dark that it was dripping with ink, glared in the direction of Yan Motou.

Demon Yan's face was expressionless, but he covered his mouth with his palms, and the corners of his mouth tilted up in a subtle way.

"The time is up. The brain cell activator should have taken effect. In three minutes, the retest will begin."

The examiner walked to the console.

"All candidates, please take your seats. Pay attention to the names and student numbers of your respective schools at your feet. Please choose one of the three sitting postures, sit down on the spot, relax and breathe, and enter a state of deep meditation."

A cold mechanical sound sounded above the students, "After one minute, candidates who are still standing, walking or making noise will be deemed to have violated the rules of the examination room and will be given a warning for the first time and will be directly expelled from the examination room for the second time!"

For a time, the huge underground square, filled with thousands of candidates, was completely silent.

Meng Chao sat cross-legged and chose the "dead wood pile", one of the "nine piles". With even breathing, he gradually entered a meditative state.

He imagined that he was a tree stump left after being cut down, suffering from the sun and rain, but in the extreme pain, a new life burst out, and a cluster of small buds grew out of the wound.

The laughter from a moment ago was forgotten, and the mottled nightmare came to mind again.

But this time, there was no confusion or fear in his heart, only firm belief and courage to move forward.

The sound of precision machinery operating could be heard overhead.

Rows of metal racks slowly fell.

There are also helmets connected to the rack with hoses and delivered to the head of each candidate.

Meng Chao held the helmet in his hand and felt it was soft and warm to the touch, much like crystal clear gel. Mysterious and complex runes were engraved on the surface, and spiritual energy flowed slowly between the lines, giving it a mysterious and unpredictable sense of the future.

The interior of the depression is covered with dense protrusions, which look like echinoderms and living metal, a bit numb.

"Is this the super brain?"

Meng Chao looked at it carefully.

Integrating nanochips, monster biochemical brains and quantum algorithms, the latest model of super brain has unprecedentedly powerful computing power.

More importantly, it can seamlessly connect with the human brain through bionic nerves and directly input information into the human brain.

Genetic martial arts, psychic technology and super-brain technology are the three pillars for Dragon City to compete in other worlds.

Meng Chao put the super brain on his head.

The gel-like active shell slowly adjusts to ensure a comfortable and secure fit.

The dense protrusions like echinoderms gently fit the acupuncture points of the head and cervical vertebrae, and the bioelectric current is transmitted numbly, perfectly connecting the human brain nerves and super brain crystal clusters.

Meng Chao's eyes were covered by the super brain, but his optic nerve received direct information input from the super brain.

A fluffy ball of light appeared in front of him, and a line of small words appeared in the ball: "In the 55th year of the new era, the second round of the entrance examination for Dragon City's first-class colleges and universities is about to begin in one minute."

Not only the visual nerves, but also the olfactory, auditory and tactile nerves.

Meng Chao was obviously sitting cross-legged, but gradually he felt that he was standing.

The smell of gunpowder smoke and blood filled my nose, and I could hear the ghostly howling and the howling of ghosts and wolves.

It was as if he had gone from a safe and comfortable underground square to a new world and into hell.

…

In the monitoring room, the leading teachers from each school were watching the examiner implant scenes into the Superintelligence host.

The scenes of extreme horror made them gasp in surprise.

"Why has the difficulty of the psychic test increased so much this year? Although it is a virtual test, the fear and pain the children feel are 100% through the super-brain implantation of completely realistic information. How can I bear this?"

"No, not 100%, but 120%. The impact that candidates will bear in the virtual world this year will be more terrifying than reality!"

"120%? This is the standard used by the Red Dragon Army to select elite special forces. This year's college entrance examination is too exaggerated. The fear and pain last year is still 90%?"

"It's not an exaggeration. You all know the recent discovery of the Red Dragon Army's 'Mist Investigation Brigade', right? The war is really going to escalate. If these children can't even pass the test of the virtual world, there is no need to send them to the depths of the mist.

, used as food for monsters."

When it came to the discovery deep in the mist, all the teachers who led the team were silent.

I can only watch helplessly as the examiner releases hideous monsters into the virtual world.

Soon, the scene implantation was completed.

The mind test begins.

Fog, ruins, blood moon, monsters running rampant!

The candidates' eyes suddenly changed, and they all found themselves coming from the underground square to an unfamiliar battlefield.

The classmates around him, the teacher who led the group, and everything he was familiar with all disappeared.

Alone and without support, they could only trample on the putrid corpses and explore fearfully among the broken limbs and broken walls.

"Ouch!"

The blood moon soaked the mist into steaming blood mist, and monsters emerged from the blood mist with a grin.

The mental test does not target combat skills, but only measures mental endurance.

Therefore, the Education Bureau did not choose super beasts with powerful attacks but majestic or even gorgeous appearance, but nightmares that looked like a mixture of reptiles, arthropods, echinoderms and deep-sea fish, making people unable to eat for three days just by looking at them.

biology.

"ah!"

"Help!"

"Oh my God!"

Faced with a monster with a deformed and twisted head that looked like a skinned frog and could spit out its internal organs at any time, many candidates from ordinary middle schools who were not able to receive virtual training were frightened immediately.

The better ones turned around and ran away, while the worse ones stood there shivering. As a result, they were knocked down by the deformed monster and watched helplessly as half of their bodies fell into the monster's bloody mouth.

While chewing, the monster smiled at them with its strange cloudy eyes.

These candidates couldn't bear it any longer. They rolled their eyes and fainted to the ground.

"Xiaohe Middle School, 5501342 candidate Ren Fei, the psychic index is lower than 40%... lower than 30%, warning, the candidate's psychic index continues to decline, has been below the warning line for more than 60 seconds, the psychic test is determined to have failed, and the virtual world is forced to exit

examination room."

The mental state of each candidate is displayed on the large surrounding screen, and various values ​​​​are constantly beating. As long as it is higher or lower than the warning line, the value will immediately turn red and a special alarm will sound.

In the examination room, a candidate was foaming at the mouth and twitching all over.

He was immediately forced out of the virtual world, and the super brain transferred relatively gentle bioelectric currents to his cranial nerves, massaging the cerebral cortex and ensuring mental stability.

Several people in white coats rushed over and carried the candidate who was on the verge of mental breakdown out of the examination room and received treatment.

The leading teacher of Xiaohe Middle School sighed, but there was nothing he could do.

Ever since humans unlocked genes and unleashed the ultimate potential of their brains fifty years ago, scientists and extraordinary beings have discovered that otherworldly spiritual energy has an impact on the human spiritual world that is a hundred times greater than that of the earth.

Introducing overloaded spiritual energy into the body and impacting brain cells will certainly release explosive power and extraordinary supernatural powers, but it will also synthesize a large amount of a substance called "super-enkephalin".

There are originally two types of enkephalins in the human brain, namely methionine enkephalin and leucine enkephalin. They are morphine-like neurotransmitters in the central nervous system, which can increase pain threshold and maintain mental alertness.

Stable and even linked to the emotional areas of the human brain.

Hyperenkephalin is more mysterious and complex. So far, scientists have not fully understood its structure and mechanism of action. They only know that it can control spiritual energy, form bioelectric currents, stimulate the deepest parts of human cells, and improve the energy supply efficiency of mitochondria.

hundred times.

A large amount of super-enkephalin secretion is the key for human beings to move from "mortal" to "superman".

But everything is too much, just like drinking too much water can lead to "water intoxication". If the human brain secretes excessive amounts of enkephalins for a long time, it is also possible to become "enkephalin intoxication".

In this case, excessive super-enkephalin will in turn corrode the human brain, pollute the human spirit, distort human will, and cause human beings to gradually become distorted, degraded, alienated, and turned into crazy monsters.

After decades of exploration, Chaofan Tower launched the concept of "psychic index", emphasizing that humans must control "super-enkephalins" and maintain sanity at all times, whether practicing or fighting.

The benchmark of the mental index is 100%, which represents the normal secretion of super-enkephalins.

When being strongly stimulated by the outside world and seeing extremely scary, mysterious, strange, and unknown things, the human brain's self-defense mechanism will begin to secrete a large amount of hyperenkephalin.

At this time, the spiritual index will fluctuate between 90% and 110%.

If the psychic index is less than 1, humans will have negative emotions such as fear and anxiety.

If the psychic index is greater than 1, humans will become brave, fearless and even bloodthirsty.

Regardless of fear or bravery, as long as it is not excessive, it is necessary and beneficial.

Needless to say, bravery can help people be more vigilant even if they are afraid, instantly assess the strength of the enemy and ourselves, and decisively choose to evacuate when it is time to evacuate.

Many people often "go blank" when they are extremely fearful. In fact, the body automatically transfers all energy from the brain to the muscles and uses instinct to escape.

However, the terrifying creatures and mysterious phenomena in other worlds really exceed the limits of human brain cognition.

In order to tap into their potential, extraordinary people often secrete too much super-enkephalin.

The mental index can easily break through the "safe zone" of 80% to 120%, either too high or too low.

When the mind index is lower than 80%, the negative effects of fear will gradually overwhelm the positive effects. Hyperenkephalin will turn from a good medicine that activates potential into a poison that corrodes the brain, causing humans to be coerced by unknown fears, like being stuck in a quagmire, unable to extricate themselves.

.

The more afraid you are, the more you secrete super-enkephalin, and you fall into a vicious cycle of super-enkephalin poisoning, and then you become more fearful.

When the psychic index drops below 30%, it is almost impossible to break free by one's own strength. Excessive super-enkephalins will attract a psychic frenzy and completely devour the human spiritual world.
