Chapter 77:
Of course, you don’t have to think about raising a cat at the observation deck. Let alone cats, the only ones that humans can keep as pets in the future are probably ants, and ants are probably stronger than ordinary people. I really don’t know who will escape who. .
Wait until everyone gets up.
Dong Junwei gathered everyone together and began to discuss sealing the cracks in the door.
Because of the cat yesterday, this matter had to be completed even more quickly.
As for the method of sealing door gaps, Tang Jing proposed an optimized plan based on the previous one, which is to install half of the fence for ventilation, while the other half is directly blocked, so that slightly larger animals and insects can be kept out of the door. At the same time, the amount of work should be reduced as much as possible.
According to the results of discussions with Tang Jing, the gap between the fences is going to be set to 1 mm.
Today's humans have a shoulder width of about 4 millimeters and a side thickness of about 2 millimeters. If the fence is set to this size, the top priority for defense is humans themselves.
Considering the sturdiness, the fence itself uses a 3 mm diameter iron rod, with the upper end inserted into the lower edge of the door and the lower end straight into the ground, each with a depth of 5 mm.
Calculated this way, approximately 125 stainless steel iron rods 2 cm long and 3 mm in diameter are needed.
Just making these iron bars is a big project.
Fortunately, these are just repetitive labor and do not have much technical content. During Chen Mu's training these days, he has already made many iron bars of this specification. They are now placed on a flatbed truck and are ready to be shipped together after they are completed. By the door.
However, at this time, a problem arose.
The kitten that came yesterday came again today.
Still meowing and scratching at the door.
It didn't stop until more than twenty minutes later.
No one dared to go out to check, so they could only stop the project for the time being. After all, to do this, Chen Mu had to stay under the door. Who knew whether the cat would come back and dig it out... However, the wait continued
. For three days, the little broken cat was absent every day, several times a day, and the time was irregular, as if this place had become its special place to play.
"What can we do? If it comes every day from now on, we won't dare to go out." "
I suddenly don't like cats." Du Jiajia said angrily.
Everyone talked a lot, but in the end they were still unable to do anything.
He Ying suddenly stood up and said, "How about I go outside to watch. Once it gets close, call Chen Mu in immediately." "
No, it's too dangerous."
Dong Junwei stopped him immediately.
"It won't go very far. With my speed, I should be able to escape in time." He Ying insisted.
"He Ying, don't go. The cat is definitely faster than you, and its steps are very light. You won't know where it will come from when the time comes." Zhao Xiaoyan obviously didn't want his friend to take risks.
"But we can't keep going like this. Sooner or later, someone will take the risk."
"I have an idea."
After Tang Jing finished speaking, everyone breathed a sigh of relief.
"What?"
"We can set up a lookout point."
Tang Jing said, pointing to the height of the door.
"What do you mean? Set up a lookout on the door?"
"We don't dare to go out because we are afraid of being attacked, but what if we stand on a high place?"
"Open a hole in the door?" Chen Mu answered.
"Yes, it's just like wearing a pipe before." Tang Jing said with a smile: "However, my idea is that since we are going to build an observation tower, we have to consider taking turns to sit in the observation tower in the future. But in this case, we can use the handles like before. The climbing mode must not work, otherwise only Chen Mu and He Ying can go up, and we can't let them stand guard all the time." "
Height?"
"80 cm."
"Size of the opening?"
"3 cm high, 4 cm Centimeter wide rectangle, the thickness of the door is 4.5 centimeters, but a transparent plastic plate needs to be installed on the outside side." "How to go
up?"
"It is best to use stairs, on this side of the door, slowly dig out Make a zigzag staircase so that everyone can go up."
Chen Mu and Tang Jing are now more skilled in cooperating, and their communication is more concise. In a few words, the plan was basically finalized.
"Wait a minute."
He Ying shouted and asked, "What do you mean, make a hole in the door and let a person watch and watch there?"
Tang Jing said with a smile, "That's what you mean, not just It's because of the cat incident. I actually wanted to do it a long time ago. After all, I now know that there are many dangers outside. If I wait until someone hits the door to respond, I'm afraid it will be too late." "So, in the future
, Do you need to keep a lookout for a long time?"
"Well, even at night, so I asked Chen Mu to make the place bigger, just to consider putting a bed in the future." "
But, I can't see outside at night, is it necessary?" "
Look now. Just because it's unclear doesn't mean it won't be clear in the future." Tang Jing didn't explain too much.
"This method is good, but the workload will be huge." Dong Junwei frowned slightly.
"Take your time." Chen Mu sighed: "There's nothing we can do now anyway."
...
Because of that naughty kitten, there was no choice but to add a larger project before the project of sealing the door crack.
Fortunately, this observation tower will be needed in the future and will have to be built sooner or later.
However, this matter can only be done by Chen Mu alone, and no one else can help him.
From this day on, Chen Mu came to the door early every morning and began to modify the inside of the door.
What he had to do was actually to dig out a staircase above the door that people could walk on, then lead it to a higher place, and then dig the door through so that he could see the outside clearly from the inside.
In this way, if something is approaching, you can be alerted as soon as possible.
The height of eighty centimeters was also calculated by Tang Jing. If it was too low, the field of vision would be poor, and if it was too high, people with poor eyesight might not be able to see clearly.
This project is the same as sealing door gaps. It is not technically difficult, but the amount of work is very large.
Three more days later, the staircase was only a quarter complete.
According to this progress, it will take about ten days to complete.
And the most embarrassing thing is.
When Chen Mu worked every day, a group of people could only watch and couldn't help him in any way. This was very awkward for the other classmates who were all classmates, but there was nothing they could do about it.
At the beginning, Wei Dalei organized people to cheer and encourage Chen Muge to death, and drove them away with shouts and blasts.
Chang Junyan was even more creative, saying that he would sing to cheer Chen Mu down below, but as soon as the first lyrics came out, Chen Mu almost fell down from his height - it was so unpleasant!
Only He Ying can really help, but he only occasionally climbs up to give him water and towels to wipe away sweat.
The days passed quickly.
Another three days passed in the blink of an eye.
The staircase above the door has begun to take shape and is about half complete.
However, on this day, after the lunch break, Chen Mu was preparing to start work when he suddenly heard a rumble of thunder outside.
Subsequently.
It rained heavily.
