I understood what I understood when I looked at the things that came together, it was a map from here to the Great Wall of the North.

I don't know if my dad left this map for me or for me, but I began to memorize this little map.

It's strange that the map has a hole in it, but it has a star in a nearby place.

I found that this place is not particularly far from the hole, which is about 5,000 meters away from the hole of the North Great Wall.

I thought that after my father came here yesterday and said that he had missed important information, he ran all the way from here to the North Great Wall.

I looked at the place where the route began, which was one of the walls of the lab.

What I found, there was a window that let in light.

The location is a bit awkward on the second floor against the wall, but the map shows that it is the starting location.

There is glass here, and there is a glass cover in front of the hole, how do you solve these problems?

I felt the sound of Han Dong getting up from the couch, and I wrote down the map and immediately scrambled it.

I'm thinking about repeating the same thing as my dad tonight.

But at this moment, I need to get rid of the person in front of me named Han Dong, Han Dong got up and yawned, and then called to ask me what I was eating.

When I said that I could do anything, Han Dong ordered the bridge rice noodles for me.

An hour later, an outside security guard brought things in, and after eating, Han Dong packed them and put them at the door of the room.

The moment the door was opened, the sound was particularly noisy, but Han Dong did not leave the room.

Han Dong seemed to be with me the whole time, and I thought about it and said, "What should I do if I want to go to the bathroom?" ”

Han Dong opened the sliding door on the other side, and it was actually a makeshift toilet.

Some are rudimentary, and the toilets are made of stainless steel, with a square groove connected to the water pipe.

In the evening, Han Dong asked for quilts and blankets.

Spread on the floor and slept on either side of me, I leaned on the toilet and he leaned on the door.

I once offered to swap places, but Han Dong also refused.

It's my first night here, and the noise of the construction site isn't very clear when I'm standing.

But after lying down at this moment, the ground built against the iron plate, everything outside was very noisy, and I asked Han Dong why he didn't stop working here at night.

Han Dong just said that in order to catch up with the schedule, the machines here will never stop working, but I lost sleep for a long night.

Han Dong slept very peacefully, and the steps that were originally planned to knock him out were omitted.

Thinking about it, Han Dong probably thought that my dad wouldn't talk to me too much, so letting me come here wasn't actually asking me to take my dad's job.

Instead, they used it as a hostage, and they probably suspected that my dad was in league with some organization outside.

You want me to restrain my dad, and believe that I can't fly out with wings in here.

But they probably didn't expect that my dad jumped into the hole, and I guess I wouldn't have thought so if my dad hadn't told me in advance.

I easily pushed open the door and went to the leftmost window on the second floor, as I remembered.

When I touched it with my hand, it was soft, and when I tore it open, I found that it was several layers of plastic wrap.

I really don't know when my dad prepared for it, but he did so many things in just one week.

But no one knew what Dad was going to do at the time, and he must have been very lax in his management.

I stuck my head out and saw that there was an air-conditioned outdoor unit platform outside.

I came to the platform and put the plastic wrap back properly.

Looking at the garbage pile below, you should be able to jump off it at some distance from the ground.

Thinking that my dad would really choose a place, I jumped down to the sound of noisy equipment drilling.
