The voice from outside the door was very young and full of vigor, it should be a young man.

Li Tongchen frowned and said "wait a minute". He pulled out the bulletproof vest from the closet and put it under his jacket. He hid a stun gun in his pocket and grabbed his right hand firmly before opening the door.

Outside, except for a young man in a headwind express overalls, there were two guards.

Since the last time he revealed his true identity in the game, the government has suddenly appointed several guards for him in the name of taking care of important scientific researchers.

Although he did not know which comrade-in-arms of the Salvation Army was hiding at the top, Li Tongchen was very grateful.

But he also felt that there was no need for it at all.

You must know that he had spoken to the commander-in-chief. Although he wanted to be modest, Li Tongchen knew in his heart that the commander-in-chief paid him unusual attention.

Therefore, if he is really in danger, I believe that the commander will directly help him.

"Hello, old man, your courier." The courier boy in front of him smiled and handed the box to Li Tongchen.

The guard next to him quickly took the express box and said, "Mr. Li, wait a moment."

He used a portable security checker to scan the express box, and then handed it to Li Tongchen again.

Li Tongchen reluctantly took over the courier and said:

"Little Wang, don't be so troublesome, you are too careful."

The guard Xiao Wang hurriedly stood at attention, gave Li Tongchen a salute, and said:

"Mr. Li, you are a national treasure of our country, on the same level as Mr. Yuan. Your safety is too important to be careless."

"Okay, okay." Li Tongchen knew that he couldn't talk to the other party, so he nodded to the courier, and after signing for it, he took the courier back to the house.

Li Tongchen had some doubts in his heart. He didn't know who suddenly sent him a courier package. He used scissors to open the package box of the courier package, and he saw that there was a small bottle wrapped in plastic foam.

The moment he saw the small bottle, Li Tongchen couldn't help but shudder. There is a red eye icon on the bottle!

It is an icon belonging to the "real doomsday game"!

This is, could it be... Li Tongchen suddenly felt a little short of breath.

At this moment, the mobile phone on the side suddenly shook, and then the red icon of "Real Doomsday Game" flashed, showing a message:

Brain Domain Evolution Liquid, one serving, take it directly.

Truly a commander's reward!

The commander still chose him!

Although he had vaguely guessed the result, Li Tongchen could not hide his excitement.

Picking up the small bottle, stared at the transparent liquid inside, then opened the bottle cap without hesitation and drank the liquid inside.

Although I don't know what this brain domain evolution fluid is, since it is a reward issued by the commander, it is naturally a good thing!

As for the idea of ​​sampling the liquid inside for research, Li Tongchen didn't even think about it.

If he really did that, not to mention that the possibility of being able to study and understand is infinitely close to zero, just to say that this might create a bad impression on the commander-in-chief would be worth the loss.

Maybe, he will be directly removed from the commander-in-chief.

After drinking this so-called brain domain evolution liquid, Li Tongchen looked at the remaining drop of liquid hanging on the inner wall of the bottle, and thought about it, poured a little wolfberry water from his thermos cup and rinsed it, and then clucked again. All drank.

After drinking, he smacked his lips and frowned. Different from what he imagined, this brain domain evolution fluid still has a sweet fruit flavor, and it seems to be peach flavor, which happens to be his favorite flavor.

Sitting on the sofa, Li Tongchen didn't feel anything. Instead, he felt very peaceful and was about to fall asleep.

This brain domain evolution fluid seems to be a relatively mild medicine, and it will not produce any reaction immediately...

Li Tongchen was thinking about it when he suddenly felt a splitting headache, as if a bomb had appeared in the core of his brain and exploded suddenly!

In the next instant, he only felt the discomfort of the swelling in his eyes, the pressure in the eyes instantly increased, and at the same time, his nose was cold, and a liquid flowed out instantly.

He raised his hand and touched it, it was sticky and red, with a smell of fishy sweetness. Nosebleed. Then came the extremely severe tinnitus, which made him feel as if he was in a big bell, with a splitting headache!

The intense headache instantly knocked Li Tongchen down, as if his brain was starting to tear apart, and at the same time something new was growing!

Li Tongchen groaned, and finally couldn't bear it anymore. He rolled his eyes and fainted from the pain.

I don't know how long it took, Li Tongchen woke up faintly on the sofa, only feeling hungry, the smell of blood in his mouth and nose, and he didn't know what happened for a while.

His eyes became a little blurry at this time, and there was a buzzing sound in his ears, and there were many noises.

Raised his hand and touched his nose, the nosebleed had stopped.

Li Tongchen took off his glasses and wanted to wipe them, but at this moment he found that the scene in front of him was much clearer.

He couldn't help but froze for a moment, then put on his glasses again, and this time it became much blurrier.

His hands trembled, he lost his glasses, his eyes were bright again, and he finally understood that his presbyopia had disappeared!

His eyes have completely returned to normal at this time!

At the same time, he only felt that his brain was very refreshing, as if he had touched the cooling oil.

This is... similar to some kind of cranial nerve modification surgery, and incidentally, the nerves in his eyes were also modified!

Li Tongchen's brain was very easy to use at this time, but he felt that the speed and clarity of his thinking were several times higher than usual.

What's up with just the murmur in the head? What a mess.

Li Tongchen heard clearly at this time, as if there was a voice explaining the weather forecast in his mind, and there were some voices or two people talking, or the roar of animals, or other messy advertisements and so on.

He frowned, turned on the TV, and switched to the center set.

"Today night to tomorrow..." The same voice in his head came on the TV~lightnovelpub.net~ He immediately switched to another channel, but this time it was about man and nature, and the animals inside were brutally fighting. Listen to him. The arriving animals roared exactly the same.

It was followed by infomercials, then international news.

The voices on these TVs all appeared in his mind at the same time, even if the TV was turned off!

What type of situation is this? Is your brain connected to the TV?

Li Tongchen was a little puzzled, but because of his professional knowledge, he thought of another possibility at the same time.

An exciting possibility!

Then he took a deep breath and immediately dialed the number of his medical laboratory.

"Xiao Chen? Help me prepare a brain CT scan immediately, and I'll be there in ten minutes!"
