The Mysterious Return of Hogwarts

Tang Yuan and Wang Tianyi left the Brain Library.Behind them, behind the Great Mesh Wall, the scholar who had left long ago suddenly turned around and stared at them as they left, the corners of his mouth raised in a happy arc.

Although they can't get in, it's still very troublesome. The neutrophil white blood cells seem to be different from ordinary white blood cells. Normal white blood cells should only destroy bacteria and viruses. Who would have thought that they would go to the brain to find information.

But they still have to eliminate those viruses, as long as they divert their attention.

It seemed that the plan was going to speed up. He had to go back and remind everyone, otherwise it would be quite troublesome if he was discovered.

The scholar snorted and strode into the library.

The guards standing on the watchtower guarded the place meticulously.

Absolutely no cells from the outside will be allowed to enter the brain.

But correspondingly, the cells inside cannot escape.

……

"Brother, I just thought about this mission carefully. Since it is to save the world, we only need to fundamentally prevent this infected person from turning into a zombie." Wang Tianyi discussed with Tang Yuan. "Then we just need to find a way to kill the brain. Even if those viruses come in, there will be nothing we can do."

In the movies he has seen, the most direct way to deal with zombies is to blow out their brains.

Tang Yuan replied: "Your method is good, but it's not that simple."

"The mission goal does not say that it is just to protect the world. For our cells, protecting the peace of this 'human body world' is also one of the goals. If we act hastily, the mission will directly fail. And even if it is just to protect the outside world The world, we can’t destroy the brain at the moment.”

"Why? Although we were stopped in front of the Great Mesh Wall, as long as we gather our strength, there must be a way to overcome that obstacle."

Tang Yuan shook his head: "Let me ask you a question first. Zombies are all immortal. No matter if their limbs or bodies are knocked off, they can move, but only a headshot will stop them from functioning. You know this is why?"

"Is the head their weak point?" Wang Tianyi was stunned. In fact, he didn't know why. After Tang Yuan said this, he also felt very strange.

Since zombie viruses can infect all cells, in theory, all cells in the body are the same, so why is the brain so fragile?

"You actually stopped me from asking. That's how it's done in movies."

"Everything that happens, has a reason."

"I have said before that the research purpose of zombie virus is to use it as a biological agent that can make people stronger. It is an accident that a person becomes a zombie after being injected with this agent, or the human body cannot withstand the effect of this agent. , leading to evolutionary failure.”

“Following this line of thought, the next question arises, why did it fail?”

Wang Tianyi thought thoughtfully and said slowly: "It's because the human body is resisting the zombie virus infection."

"Yes, the immune system will block the virus, and white blood cells will kill infected cells. Coupled with the accelerated metabolism, a large number of dead cells will appear. As this immune battle intensifies, the virus will gain the upper hand and then attack the brain. .”

Tang Yuan pointed to his brain: "From the time the virus comes in and before it infects the brain, the infected person will remain rational, control his instinct to eat and bite, and will have fever all over his body, showing symptoms similar to a cold."

"Then our human body is at this stage, but if it continues, those viruses will definitely reach the brain." Wang Tianyi subconsciously looked in the direction of the brain library.

"After the virus enters the brain, it will infect brain cells. However, due to the blood-brain barrier, our immune cells cannot enter and kill the virus, so the brain is very hopeful to complete the mutation intact."

"Although the zombie's brain has been corroded by the virus, part of it still controls the biological instinct - heart beating, blood circulation, digestive system, hearing, smell and remaining intelligence."

"Our first step is to destroy the zombie's various senses, so that it can't carry out biological instincts. If we don't attack its brain, it will die in a few hours because the brain will be completely corroded."

"So let's not talk about whether we can pass the blood-brain barrier. Even if we get in, we may not be able to damage the brain. Don't forget that what we are playing are cells of this body! Normal and healthy cells that have not mutated!"

"Then we have no choice but to wait for the virus to hit?" Wang Tianyi scratched his head. "We are a bit passive. The body's immune system alone will eventually fall. Now we can neither directly destroy the brain nor completely eliminate the virus. No matter what we do, it is wrong."

"I said healthy cells can't do it, but I didn't say mutated cells can't break down the blood-brain barrier." Tang Yuan said suddenly.

"Wait..." Wang Tianyi did not respond. "What did you just say?"

"That scholar cell is hiding something, so it is still necessary to personally enter the brain to find clues."

Only then did Wang Tianyi realize that he had followed Tang Yuan in a big circle, and finally returned to the vicinity of the brain, but this time it was on the other side.

"Hey, didn't we talk about finding side quests?"

Tang Yuan smiled easily: "I lied."

"Then Qi Xiu and Qi Zhi were separated, weren't they?"

"On purpose, just to divert their attention." Tang Yuan took Wang Tianyi and hid in the corner, looking up at the guard on the observation deck.

"Their sight? Damn brother, you are not honest, aren't you cheating on your teammates?" Wang Tianyi misunderstood that the "them" mentioned by Tang Yuan meant the brother and sister who governed the country.

"It diverted the attention of those brain cells, making them think that we were going to eliminate the zombie virus honestly, instead of killing them both, you idiot." Tang Yuan was speechless. "But completing side tasks is indeed useful, and it will help us decipher the worldview..."

"Ah hahaha, I said you can't cheat your teammates. No, you cheated me before, you treacherous bastard."

Tang Yuangang was thinking about how to ask Wang Tianyi to do an experiment, but he started to curse himself, so he couldn't be softer.

"Screen, scold as hard as you can. After you scold, do me a favor. If you help me, I'm also helping you. Let's complete the task together." Tang Yuan turned his head and exposed his lower eight teeth to Wang Tianyi.

"Don't laugh."

"What?"

"It's scary."

Tang Yuan touched his chin. It seemed that his imitation was not good enough. He originally expected that this kind of smile would make the other person feel refreshed and confident, but the result was the opposite effect?

"What help do you want from me?" Wang Tianyi said weakly in the end. He had no choice in dealing with a shameless person like Tang Yuan.
