After the defensive weapon of the high battery was completed, the most important thing left was the escape route.

But this project is relatively simple, and the amount of work and technical content is not as large as that of a lift.

In the next two days, Chen Du turned into a groundhog, pouting his ass and making holes in the wall, specifically separating the masonry from the wall, and then moved it away by Wei Dalei and others.

After two days of concentrating on this, a passage for three people to pass side by side appeared in front of me, and the moment the outer wall was opened, the sunlight shone in, which was refreshing.

This passage is located on the opposite wall of the door, and there is a large area of greenery outside, which is unlikely to be seen even if there is surveillance.

But for the sake of safety, Chen Du set up the exit of the passage very secretly, and also considered insect prevention and waterproofing.

After the completion of these two major projects, the overall safety level of Qiming has been raised to a new level.

July 7th.

It was He Ying's turn to be on duty with Lu Shanshan.

Today's duty system is also much more perfect than before, whether it is day or night, it is two people on duty together, which is a waste of manpower, but considering the safety of everyone, it is still worth it.

In principle, there must be someone on duty 24 hours a day at the lookout, so someone must bring them food.

Today's lunch was brought to them by Chen Duan.

The work of delivering meals is also stipulated, and Chen Dui is actually not on the list, considering the intensity of his work, Dong Junwei didn't even arrange for him to be on duty, or Chen Dui himself proposed to be on duty for one night every month.

The main reason why he delivered the meal today was because Chen Du happened to be going to the lookout.

These days.

No matter how busy he was with other tasks, he would find some time to go to the lookout and make adjustments to his current telescope.

Although the principle is very simple, a high-powered telescope with real practical value is really not so easy to do, and after so many days, the effect is always unsatisfactory.

An arm-long monocular was placed on a one-man tall shelf.

If you don't have a telescope, to be honest, there is not much point in looking, because at this height, even the ground at the entrance is not so clear.

When Chen Duan came up, He Ying was standing upside down on the bed with her hands in the air, her feet dangling, very steady, according to her, this type of exercise is especially good for physical fitness and breathing control, and she also suggested that Chen Duan try it too.

After Chen Dui tried it a few times, she could do a handstand, but the time was far from very good, and even if this girl didn't use her abilities, she was far superior to Chen Du in terms of balance, durability, and skill.

In terms of physical skills, He Ying is indeed very talented.

Even in one-on-one fighting, he can fight back and forth with Wei Dalei, and in the case of holding a sharp weapon, Lao Wei may not be able to win her.

Because of too much work every day, Chen Du tried a handstand for a few days, but he still couldn't stick to it, which is also what he admires He Ying.

"What are you going to eat today?"

He Ying saw the upside-down Chen Duan walk into the room and turn over.

"Stir-fried potatoes with green peppers...... You're really training against time. Chen Du put two plates of food on the table beside him.

"It's the most boring thing on duty, and I have nothing to do."

"Lu Shanshan isn't looking at the outside very seriously?"

"We'll take turns." He Ying came to the window and said, "Shanshan, let's go eat first, I'll take care of you." ”

Lu Shanshan snorted, "Okay, senior sister." ”

The so-called lookout, in fact, is to look out through the glass window, if you find some wind and grass, use a telescope to look carefully, although the current telescope effect is not very good, but it is better than nothing.

"You're here to improve the telescope again?" He Ying looked out absentmindedly.

"Hmm." Chen Du dismantled the telescope and said, "Don't you want to see more clearly?" ”

This monocular, the shell is made of plastic, which can be retracted, after Tang Jing explained all the principles and details, the rest is only to rely on Chen Dui to slowly explore, because some subtle dimensions are impossible to determine.

He Ying smiled and said, "I think, don't say it, I've seen things running around in the teaching building several times, it seems to be a cat, it seems to be a dog, maybe it's Xiaohuang." ”

"So, it's a little more fun to be on duty with this telescope, isn't it?"

"Uh-huh."

"Have you ever seen anyone walking?"

"It's so far away, even if there is, I can't see it clearly, I can only see the cement path below, and I haven't seen anyone."

"Pay more attention to the direction of the cafeteria."

"I see."

Lu Shanshan had finished eating at this time and came back to replace He Ying.

He Ying held the plate and watched Chen Du busy while eating.

"You say, where will the people of Qingbei spy on us?"

Since the last time Chen Duan guessed that he was being watched, He Ying always had some pimples in his heart.

"Unless the other party also has a telescope, or someone with visual abilities, it shouldn't be very far, and if the distance is too far, it won't have time to follow us when they find us out."

"Where would that be?"

"There are a lot of possibilities, such as...... Over there. ”

Chen Dui said, pointing to another storage room not far away.

It was the opposite direction to the cafeteria, and it was one of the few places around where you could shelter from the wind and rain.

"Where?" He Ying squeezed over, because of the angle, it looked more difficult, she put her head on the glass, looked for a long time, and asked, "It seems that this is really possible, do you want to go over and scare them now?" ”

"You're really a daring artist."

"Awards, awards."

He Ying smiled and said, "But I don't think Qingbei and No. 1 Middle School are as powerful as I imagined, and the few times I fought with them, the other party suffered." ”

"That's because people don't regard us as the main opponent, and once they really point the finger at us, the number of people alone can kill us."

"Cut, you're always so cowardly......"

As soon as He Ying wanted to say something more, she heard Chen Duan pull the telescope in her hand open and said, "This time it should be fine." ”

"Really? I'll try ......" He Ying was suddenly eager to try.

"What did you just say?"

"It's nothing, I said you're handsome."

Chen Du "......"

After several days of debugging, Chen Duan finally adjusted the telescope to the best state so far, and could clearly see the surrounding environment.

After taking a few glances at it himself, he handed the telescope to He Ying.

"Wow, that's clear! It's not the same as the previous ones. ”

He Ying held the telescope in his hand and shook it around, constantly admiring.

I have to say that human beings are born with a habit of voyeurism, of course, to put it nicely, it can also be called intellectual curiosity.
