Doomsday Simulation: This Is Not a Game

Chapter 43 Deduction
"Anyway, I still want to thank you for digging out this underground passage leading to the interior of the community for me!"

Song Han chuckled, and then used the resources in his system backpack to exchange for a bonfire camp and put it in front of him, and then directly archived it!

After saving the file, Song Han no longer had any fear, directly supported the cave walls on both sides with his arms, and then crawled out from that small hole!

The internal area of ​​this community is very large, and the entire community directly occupies the planned plot of an entire street, and the shops and residential buildings in all directions, together with the walls surrounding them, completely surround the entire community. Strictly!

Apart from the four residential buildings in the middle, the rest of the interior has already been filled with overgrown shrubs, just like what Song Han saw from the top of the residential building. In that case, it is not too much to say that this is an urban forest!
"There are only two entrances and exits in this community, one south and one north. The south entrance is relatively large, with an eight-meter-wide passage; the north entrance is relatively narrow, only a four-meter-wide passage, and both sides are three meters high. the wall."

After getting out of the ground, Song Han didn't act in a hurry, but carefully lay down among the weeds and listened carefully to the movement outside.

The sound of rustling animals came from outside, occasionally a low pheasant crowed or two, Song Han even heard a few pig snorts!

This is indeed a natural farm!
Of course, among the deep calls of these animals, there are also many hoarse roars!

There are also a lot of zombies in this community!

"The current situation is that if I plan to close the entire community, I have a total of 12 meters long passages that need to be blocked, and then two meters high is definitely not enough, so I need at least four meters high!"

"That is to say, if I want to make a granite wall to seal the entrance and exit, I need at least 48 pieces of granite material!"

Song Han checked the granite material in his backpack:

Granite X37
After all, although those things are minerals, and the output is not large, Song Han can't stop Song Han from picking up bits and pieces and breaking them down, not to mention that many of these things are of other types rock!

"Another problem is that granite is not corrosion-resistant and cannot stop the frequent acid rain in spring, so I have to do some treatment on these walls before they can be used with confidence."

Song Han thought for a while, and re-read the mall after his system upgrade.

The last time I was only concerned about being happy, I didn't have time to take a closer look at it.

It is best to have something that can treat these granites.
When he was thinking this way in his heart, Song Han, who was flipping through the shopping mall, suddenly had a bright light in his eyes: "There is really such a thing?!"

I saw a column in the mall that read:

[Alkali-resistant and acid-resistant composite paint formula: After use, you can gain life skills [Engineer], and you can exchange building materials for free and equal amounts into alkali-resistant, acid-resistant, and corrosion-resistant building materials. 200 Simoleons! 】

"The problem now is that there is no money."

Song Han scratched his head worriedly, and looked at the simulated coins in his backpack: 44 simulated coins.

Thirty of them were [-] Simoleons that he saved after three days of saving up when he quit the game and lived in the real world!
"It's not impossible to rely on saving alone, but saving for such a long time. First, just buying the life skills of an [engineer], I feel that the cost is a bit high. Second, I have never saved so much in playing games! It is really insulting to me as a 'high-end player' Golden signboard!"

Song Han squatted in the grass and didn't rush out to explore the community, but began to carefully plan his next course of action, first clearing up the whole train of thought before talking!

"From the day when I stood on the roof and looked into the community, there are not a few zombies in this community. I definitely can't clean them up by myself. I still have to rely on some movement to attract them all out!"

And what movement can attract the zombies in the entire community?
Of course it has to be a big bang!

"I've densely placed seven parts of black powder on the bottom of the wall. According to the instructions, the explosion effect of each part of black powder is equivalent to that of one detonator, so seven detonators are enough to blow up the wall. Big mouth!"

What's more, when he helped build the fence, he deliberately stole work and reduced materials, and mixed a lot of waste plastics to reduce the cement setting of the fence!
"That place is not very far from here, and the sound from the explosion is enough to attract the zombies to pass by! Then I can use this opportunity to seal off the whole community first!"

So there are some problems in this process:
First, he must return to the underground passage from the outside, and then ignite the detonator buried outside the wall!
Second, you still need enough granite materials to build the wall!
Third, before building the fence, I had to replace the granite material with an alkali-resistant and acid-resistant material. Otherwise, when the fence was repaired, the zombies outside would definitely wander back again, and it would be even more troublesome to replace it at that time!

Song Han first kept these problems in mind, and then continued to deduce them assuming that these problems had been solved:
"If it goes well, I can go back to the bank building from the outside, and then go back to the garbage collection station through the subway gate and the passage again to light the black powder, and then go back directly along the original road and drill into the road leading to it." The underground passage of the community, while the zombies are being attracted out, complete the reinforcement of the community!"

Then in this process, three problems will arise again:
First, when I returned to the bank building and returned to the building through the internal access door in the lobby on the first floor, I was bound to fight with the zombies wandering around;
Second, when I went to the garbage collection station through the underground passage to ignite the black powder, or on the way back here, I was bound to have a fight with those people!

Especially when I came back, I guess the wall had been blown up by myself at that time.

Seeing that the last hopes and hard work were destroyed by him, and this group of people was in danger of being directly made dumplings by the zombies, it would be no wonder that this group of people would not work hard with me at that time!
Third, what if the zombies in the community are not all attracted, but a small number remain in the community?
Even if there are only a few of them, if I can't complete the blockade of the entire community in the first time, those zombies who cannot enter because of the narrow underground passage and the explosion will attract countless zombies from all directions, they will be killed. Will come back here straight away!

In this way, all my hard work will be in vain!
