【Upgrade Lab】

Su Wen clicked on the screen, and the room immediately vibrated violently, and the surrounding walls began to expand outward, and at the same time, the materials in the laboratory disappeared, leaving only some wires lying in place.

After a few moments, the lab's room had doubled or so.

At the same time, a terminal appeared in the room.

Su Wen just wanted to walk over, but suddenly there was a sharp pain in the back of his head and palms, and his eyes turned black.

He stumbled and fell to the ground.

After a few seconds, the pain wore off, and he got up from the ground.

Su Wen reached out and touched the back of his head for the first time, and suddenly felt a groove appear there.

Stretching out his two hands, he saw two more interfaces in his palms.

His eyes widened, his hands stroking back and forth, his head blank.

After a long silence, two words popped out of his mouth.

"Cow batch!" Su

Wen walked to the terminal.

The screen on the wall has been moved to the terminal, displaying the materials needed for the next level of upgrade.

[Alloy plate 20 kg, wire 416 meters, coolant 20 liters.

"It will probably take a few days to find these things.

He clicked back and saw that the exchange was open.

[Exchange: All items to be traded should be placed in a white frame.] Turning

his head to look at the wall, an area surrounded by a white frame line appeared.

Click on the exchange and see that someone has already put the food on it.

He walked over to the wall, picked up a few tomatoes and some fruits he didn't know, and hung them up in exchange for the materials needed for the next level.

Regardless of whether anyone buys it or not, hang it up first.

Picked up a cucumber, clicked and nibbled it, and walked to the terminal to open the chat room while nibbling.

【Chat Room】

Su Wen looked at the numbers above for the first time.

63548536978。

Sure enough, there were more than a billion less.

Compared to last time, this time it seems to be acceptable.

Stared at the chat room for a while, but didn't see anyone who had been upgraded.

It seems that there should be few people who have reached the second level at present.

[It's so difficult to get materials, I have enough wires, where can I find

the power generation device?] [Who has a surplus power generation device...]

[Has no one upgraded?

] [I didn't go out just now, a chicken ran in, I killed him, and finally there was something to eat.]

[Brother, do you have a fire?can't you eat it raw!

] [Is there a big guy to talk about it after upgrading

, is there a toilet??] [I picked up a bunch of alloys, and now there are still dozens of meters of wires to upgrade, is there anyone to change with me, private chat.] When

Su Wen saw this person, he immediately clicked on his avatar.

This is the only level 2 he has seen at the moment.

The next level of upgrading requires 20 catties of alloy plates, and few people know that since this person can take it out and exchange it...

Su Wen: Hello.

Liu Tian: Food, paper, wires, don't bother me if you don't have it.

Su Wen looked at the tissue at his feet and raised his eyebrows.

Boy.

Looking at the pile of things in the corner of the wall, the corners of his mouth hooked into a smile.

What this person wants, there should be few people who can satisfy him.

The most important thing should be paper, right?!

Su Wen: I only have paper and cucumbers.

Liu Tian: Yes.

Su Wen: How many alloys are you going to exchange for?

Liu Tian: Three catties.

Su Wen: Deal.

He walked to the corner, picked up a piece of paper, aligned it, tore it, and took two more cucumbers and put them in the white wire frame on the side.

Su Wen: I've hung up, password 111.

Liu Tian: Okay.

In the next second, three catties of alloy appeared in the corner of the laboratory.

Before he could take a look, the private chat of the person opposite came again.

Liu Tian: Brother, where did you get your paper? Can you change it for me?

Su Wen: I don't have much.

Liu Tian: I'll give you another pound of alloy, damn, it's really damn bad to have no paper, I just pulled the leaves I used, I don't know if it's allergic, and now my ass is fucking swollen.

Su Wen looked at the chat history on the screen and burst out laughing.

Good guy, I'm afraid it's not that you are allergic to leaves, but you have encountered spicy seeds

! Wait!

Leaves?

Why didn't I expect that there were so many plant leaves in the first research institute...

If they are all picked back, maybe there are people who are willing to buy them to wipe **.

Su Wen patted his head in annoyance, I must remember it next time!!Su Wen

: I have one left...

Liu Tian: Brother, give me another half sheet, and I'll give you another two catties of alloy, a total of three catties, okay? I'm allergic, I'm really uncomfortable, please.

Su Wen: Uh... All right.

Liu Tian: Thank you, brother, when I find more food one day, I will give you a share!

Su Wen: Thank you.

He stretched, looked at the alloy that reappeared in the frame, and withdrew from the private chat.

[Brothers, there are still two hours to refresh the research institute, are you ready?]

[I'm not going out, anyway, I got a lot of food yesterday, and he meows for a day to earn a day. [

I'm going out to explore, I don't want to nest in this small room, even if I die, I'm going to die outside!!

] [What kind of world is this??Is it a game world?] [

How is it possible, it must be another world, let me tell you, the novels I read before have this type. [

Tell me more

!!] [I want to hear it too!] [

Then I'll tell you about it, have you read a novel about the strange talk of rules...]

....

"The new institute is about to be refreshed, please get ready for the host.

This time, the left and right research institutes are empty, and the middle one is a biological research institute, which is dangerous.

There are four cages inside, each containing a zombie.

There was a scalpel on the table.

The terminal contains a copy of the intermediate combat data and the zombie experiment data.

Hosts can choose which institute to enter.

Su Wen was watching with relish, and the voice of the system sounded in his ears.

"I'm excited!" he muttered casually, and immediately exited the chat room.

"There are zombies!"

"It seems that this time it is still a bit dangerous.

Su Wen directly ignored the other two rooms.

As he spoke, he picked up a fruit that looked like a mango and nibbled on it.

Eat well, and when you have the strength to kill zombies!

While eating, you can recall in your mind those zombie movies you have watched before, and learn the process of solving zombies in them.

Su Wen sat cross-legged on the ground and sighed leisurely.

"I haven't killed a chicken, so I was asked to kill zombies!!"

"When you go in, you must get the scalpel first, and then download the fighting data and zombie experiment data." He

was eating, and his mouth was still fragmented.

"I just don't know if the zombies will break out of the cage..."

"Just in case, let's practice in advance!!"

Su Wen directly forced himself not to think about it so much, he finished nibbling on the fruit, got up directly, stood in place and began to practice according to the actions in the movie in his mind.

"Left hook, hook again, the person who meets me is in danger!!hum, ha!!"

"Eat a knife!" After

a while, the horn in the room sounded.

"After a minute, everyone is asked to choose whether or not to enter the institute. "
