It took Su Wen three hours to empty all the materials in the room.

The seven monster corpses, he didn't move back.

"There are a few more monster corpses in the place where I live for no reason, tsk... "

Let's see what will be given after the upgrade, and then decide whether to move or not!"

[Upgrade]

A relaxed smile appeared on Su Wen's face: "It's finally time to upgrade." Click

.

"Boom!"

there was a loud noise, and the room began to expand outwards once more.

After a few minutes, the movement slowly subsided.

Looking at the empty laboratory, Su Wen couldn't help but say: "Hey, if there is such a big house for me in the real world, no, half of it will do, and I can wake up laughing when I dream!" This can't

be blamed on Su Wen for not seeing the world, but the current laboratory is really ridiculously big.

Su Wen estimated that it was about two hundred square meters.

"Harm, in reality, in the suburbs, housing prices have risen to eight or nine thousand, and the hardships of ordinary people are either saddled with a mortgage for decades, or ah, they can't afford to buy a house for the rest of their lives!" Su

Wen sighed while looking at the materials needed for the next upgrade on the screen.

[Upgrade requires: Scan fifteen different research reports.]

"Well, there are a lot of materials left this time, enough to use next time.

"Just scan the test report again, it shouldn't be that difficult. "

I've been in the lab before, and I've seen a lot of experimental reports, so it's not difficult on the whole, it mainly depends on luck.

"Let's see what more labs have in the lab after this update!"

"Oh?culture room?"[

Culture room: It can be used to incubate organisms and cultivate organisms. Su

Wen rubbed his eyes, his eyes full of incredulity.

After this update, it's too rebellious!!Isn't this

a proper way to cultivate pets?

If you can find a suitable creature as a pet in the future research institute, it will be a very good helper.

"That's great!!"

is one of the best upgrades in recent times.

After having a pet, you won't be as lonely as you are now, and you will have a living thing to accompany you.

"It's so lonely as snow!"

"Let's see if there's anything else." "

When I went back to the main interface, I saw a new page where all the things in the lab were sorted and categorized.

[[Food]

Tomatoes: 58

apples: 92

...

Canned beef: 70 boxes

....

Blood: 35 bottles/ml

....

[Material

] coolant: 1629 kg alloy plate: 1749 kg

...]

Everything is neatly arranged together.

"It's a lot more convenient!" The

food that was hung up before the [exchange]

was almost sold, and Su Wen hung a lot of it again.

Based on the volume of food traded, he can basically deduce that there are still many people who are still in some embarrassment in terms of eating.

Not everyone has the courage to step out of the lab.

But what does this have to do with him?

[Chat room]

[I'm finally level 3!!! room has become much bigger, it's so comfortable!!, it's a day of doing nothing and surviving. [

Brother, I also upgraded to three levels just now, haha, from today on, we are also at the middle level!

] [Medium??really fake?] [

What do you say, I'm only two levels, hahaha, don't panic at all.]

[Really, you can pay more attention to the chat room, 90% of them are level three, and occasionally a few level four and level five will pop up, don't you know if you calculate it?]

[It seems to make sense, maybe the big guy doesn't like to mix in the chat room, only those of us who have nothing to do like this.]

[It makes sense, depending on the laboratory upgrade conditions, it is good luck to be able to upgrade to level four, and if you reach level five, you are the son of Tianxuan!"

[The highest level I have seen is also level five, and there is no level six yet.

[If you look at the number of people, there are already more than 20 billion less, so you can only calculate the probability of surviving and the probability of upgrading.

[Count the big guy??

] [6, hahaha!

] [......]

Su Wen looked at the group of people in the chat room and grinned, leaning on the computer chair with his arms crossed, and fell into deep thought.

These people are right.

Based on the number of people who have died now, almost a third of them have died.

The remaining two-thirds, so far, have not been easy to move up to level three.

The European Emperor may be able to rise to the fourth and fifth levels, but there are basically only a few people like himself.

Not to mention those who are not chiefs, some are even only two levels.

"Hey..."

Su Wen could only sigh at this.

[Anyway, I'm two levels, and I'm living a life of eating, drinking

, and waiting for death~] [This time I'm really lucky, I found an endless backpack, and it's been running for a while!! no matter how many things you put in, you can fit it, and it's still time standing still~~It's so cool~

] [You use your life to play games????

] [Seeing you, I want to say that I died without regrets!!

] [Poof-I see that you all have a serious illness-]

[Attention, attention, attention, friends, I have something to say, any of you have anti-radiation drugs, I want to exchange them for anti-radiation suits.

Note that it has to be able to treat radiation sickness, not to protect against radiation, I have been irradiated, and it has to be the kind that can cure me.

Honest dealings come.

[I'll go, isn't it, radiation suits!!This kind of good thing is taken out and exchanged, you're crazy!]

[I'll !!!] [

Brother, private chat!]

When Su Wen saw this chat, he immediately clicked on the private chat.

Anti-radiation drugs, he has.

Moreover, it is not the kind that can only resist radiation made by yourself, and the most important thing is that your own medicine can treat radiation sickness.

Su

Wen: Hello, I have medicine here.

Chen Kai: My requirements have been written on it, I don't need radiation protection drugs, I need treatment drugs.

Su Wen: I'm here to treat radiation sickness, and I can repair my body that has been irradiated, any injured area.

Chen Kai: Such a powerful medicine??wait!You're level 6!!

Suwen: Uh...

Chen Kai: Big man, please wait a minute, I still need to shop around.

Suwen: OK.

Su Wen exited the private chat room.

For this radiation suit, he is determined to get it.

He believes that no one can have more medicine than he can have.

Next, it's a matter of waiting.

Sure enough, a few minutes later, Chen Kai chatted with him privately.

Kai Chen: Let's trade now.

Su Wen: Yes.

Chen Kai: Brother, your level is so high, there must be enough food, can you give me some more food?

Su Wen's fingers tapped lightly on the tabletop.

It's just a little bit of food, and it doesn't really matter much to give it to him.

Su Wen: Yes.

[Trading items: radiation medicine/1 pill, bread/1 piece] [The other party agrees to trade

] [You get a radiation protection suit/1 piece]

Chen Kai: Thank you, big guy!

Su Wen: Please help me keep it secret, and you can find me if you need it in the future.

Chen Kai: Okay!!!

Su Wen quit the private chat and got up to look at the radiation protection suits that he had exchanged.

The overall radiation protection suit is black and purple, and it is very light and not heavy to start.

Wear it on the body and wrap it tightly around the whole body.

There are two transparent frames in the position of the eyes, so Eun can clearly see the scene outside.

There is a special device similar to an oxygen mask that is attached to the nose and can breathe.
