Fang Tong went to the green belt where the little girl picked hawthorns before, and hid behind a bush of small bushes to welcome spring. He cooperated with Zheng Rui to draw a simple map in her mind, marking Zheng Rui's location with a red five-pointed star.

Zheng Rui: You can also choose a graphic to mark your own position.

Fang Tong marked his place with a white five-pointed star.

Zheng Rui: What is this, are you a white army?

Fang Tong: What White Army? It's transparent, it's not white - I'm not a member of the party, so it's uncolored......

Zheng Rui: Uncolored...... Why don't you mark a regimental emblem, hahaha.

Fang Tong: You ...... Don't be poor, hurry over.

Hey, you still think she's poor. Zheng Rui felt a little funny, but at this time, he still had to focus on business.

She stepped out from behind the moon bush in the doorway, and by the sight she had glimpsed from the sight she remembered passing by, she could discern the foundation of the school's most luxurious-looking building. According to common sense, the largest building should be used for teaching, so the probability of having a chemistry lab under the foundation here should be the greatest.

However, when Zheng Rui walked down the steps, he saw the underground restaurant with the door locked and the inside was pitch black.

She glanced at the sign posted next to her, which read, "Main Dormitory Basement Cafeteria".

Hey, the most luxurious building turned out to be a dormitory, and this school is really willing to spend money.

Since it is still summer vacation time, the middle school restaurant is of course closed. Although this lock was easy for Zheng Rui to break now, considering that there would be nothing inside at this time, she still let it go.

Let's take a look at the one next to it. The closest to the 400-meter playground should be the foundation of the teaching building, right?

Zheng Rui returned to the ground and glanced at the foundation next to him. It felt a little flatter than the school building she remembered, and it didn't look much like it.

Fang Tong: Isn't the chemistry lab underground?

Zheng Rui: It was a dormitory building, I can't remember where the teaching building is...... Was there anyone around here when I went down?

Fang Tong: No. But you better be careful.

Zheng Rui walked to the foundation of the next building, where the basement had a long ramp, which also did not look like the indoor staircase that should be in a teaching building. But it's all here, so let's go down and have a look.

Zheng Rui walked down the ramp and found that inside was the sealed door of the air-raid shelter.

It's a bit surprising that there are bomb shelters in schools, but it's not that uncommon. In the past, various municipal units have built air-raid shelters, and when this private school bought land to build it, the air-raid shelters should have been built here. Based on the fact that the foundation of the building is so close to the playground and directly connected to the air-raid shelter, it can be speculated that this should actually be the school's gymnasium, and the old air-raid shelter should have been used as an indoor stadium.

In fact, Zheng Rui's Tianbei Middle School also handled the air-raid shelter in this way. When she was in junior high school, she especially liked to play in the bomb shelter, and after turning off the lights, she really couldn't see her fingers, and she could organize an advanced version of hide and seek during free time in physical education class - but this kind of thing is really a bit dangerous.

And now, the bomb shelter may also be a good place to stay against the aliens. The sealed door that can defend against ground-to-ground missiles can also be protected against aliens.

Therefore, Zheng Rui guessed that there were people living in this air-raid shelter. And if there was no one, she would like to transfer all the things in the commissary here, and then the four of them will live in this bomb shelter, whether it is aliens or the same kind that may rob supplies, there is no need to be afraid. Even if there are people living here, Zheng Rui thinks that if he can discuss with them, let them bring the commissary's supplies to live here, and share the materials together until the army takes over, it will be extremely cost-effective.

- No, not really.

Zheng Rui suddenly thought that the little girl knew that the air-raid shelter was safer, but she lived in the basement of another building, indicating that if there were people here, she would not accept other people to live together.

Or......

- Aren't people living here?

Zheng Rui could hear her heart pounding, and Fang Tong also noticed her mood swings.

Fang Tong: What's wrong?

Zheng Rui: Strengthen the release of calm emotions. There's a bomb shelter here.

She saw black-purple marks on the rotating handle of the bomb shelter, which she thought was paint, but when she looked closer, it looked more like dried blood. Even though there was something blocking it from above, most of the blood had been washed away by the slanting rain from the rainstorm, and the rest was like paint that hadn't come off.

There must have been a battle here, and the escapees did their best to close the door of the bomb shelter and shut the inside of what had hurt them.

Zheng Rui wasn't sure if she should open it. She pressed her right ear to the sealed door and heard what seemed to be the sound of something dragging on the floor inside.

There were living creatures in it, possibly human...... It could also be an alien.

Zheng Rui knocked on the door.

Bang –

She felt something slam against the door as she looked through it.

Bang –

Bang –

The thing kept banging on the door, making a loud noise that didn't look like a human.

But the good thing is that there is only one sound.

Zheng Rui took a deep breath and decided to kill the alien.

Zheng Rui: Comrade Fang Tong, there is an alien in the air-raid shelter, it should not be the third generation, I can deal with it. But you also need to be vigilant and ready to evacuate at any time.

Fang Tong: What?! No, I can't walk on my own - don't take such risks, okay?

Zheng Rui: It's not a risk, I'll definitely have no problem dealing with a second-generation alien, just in case I let you pay attention.

Fang Tong: That's ...... That's good, that's good...... I've maxed out my abilities, so be careful.

Zheng Rui grasped the rotating handle of the sealed door and turned the latch.

Bang –

Bang –

Bang, boom –

At the same time as the door opened, the alien-shaped, slender appendages squeezed out of the crack in the door, and the huge momentum pushed Zheng Rui five or six steps away.

However, when she actually saw this alien, she couldn't help but breathe a sigh of relief - the claws of the first pair of large appendages of this alien were the original toothed long knife-shaped, and there was no transparent membrane on its back, and it seemed that it was just the first generation of unevolved aliens.

Judging from the fact that the blood stains on the doorknob had completely dried up when they were washed away, it was also a time before the rainstorm that the escapees locked the xenomorph inside, when it was likely that the second generation of xenomorphs had not hatched yet.

Zheng Rui swung his knife quickly, slashing the alien's neck cleanly, and its gray-purple head, which was close to tetrahedron with a pair of beautiful sky-blue round glasses, fell out, bringing out a blue-green slime. Then the alien's body collapsed at the door of the bomb shelter, its belly barely having time to come out of the door.

At this time, Zheng Rui realized that he had really become a lot stronger.
