Doomsday: Humanity shrinks 100 times

Chapter 79 Defensive Planning

"what do you mean?"

"I originally wanted to put it inside the tree." Lu Yuning replied.

"Dig another tree hole?"

"Well, that's what I think, but I have a few questions." Lu Yuning nodded first, then continued speaking.

He looked at everyone and continued, "The main problem is the workload. The water tank is quite large, and it would take at least two days to carve such a large hole in the tree. Also, if we need to expand it later, it would be a big problem. Not only would it be time-consuming, but it would also cause considerable damage to the tree trunk."

According to Zhang Xinyue's calculations, they may need at least a 200ml water storage container. The larger the better. If it is smaller, there is no point in storing water.

This volume is actually larger than their shelter.

It took Lu Yuning two days to complete the task at that time. Now, it is obviously not cost-effective to spend time digging a hole for this water tank.

Another more serious problem is that although the tree is very thick, we still have to consider the issue of trunk damage.

Given the size of the water tank, digging a few more holes would cause considerable damage to the tree trunk.

It might cause load-bearing problems, which would not be worth the effort.

"What should we do then?" Zou Yunxin asked without understanding.

Lu Yuning did not answer him directly, but thought for a while, then asked Zhang Xinyue:

"How high can this device send water?"

"Theoretically it's 10 meters, but actually it's about 7 meters." Zhang Xinyue said without hesitation, obviously she understood it very well.

Lu Yuning showed a surprised expression: "So high?"

"Well, it's mainly affected by pipe wall resistance, water temperature, and so on."

Lu Yuning's face lit up: "If that's the case, then it won't be a big problem. We can put the water tank outside the tree trunk."

Everyone is puzzled
"How do we put it up there? There's no suitable branch on it."

Lu Yuning said: "Build an aerial platform"

"Will it still be conspicuous?" asked Zou Yunxin.

Lu Yuning gave a brief explanation about this issue.

As they shrunk, their field of vision was limited, and one meter was actually a very high distance.

Now standing under the tree, it is difficult to see what is on the tree. I can only make out a vague outline.

If it is at a height of 10 meters, you can imagine the feeling of standing in one place and looking at something 1000 meters away before shrinking.

And based on current knowledge, people are more likely to think that things placed in the air are buildings from before the end of the world.

Everyone was stunned.

"When I was drying mushrooms, I came up with this idea: to build a platform on the tree branches to act as a camouflage. We can move some ground facilities up there, and those that can't be moved up can be built underground. This way, our shelter can be completely hidden."

Everyone looked at him in surprise.

Looking at the expressions of several people, Lu Yuning scratched his head: "Isn't this a bit unrealistic?"

"Not really, I just never thought about these issues. It sounds like something out of the blue." Zhang Xinyue said.

Lu Yuning was at a loss whether to laugh or cry.

Lu Yuning has been thinking about the follow-up plans for the shelter, and after meeting Xinghuo, these ideas have become stronger.

Spark and Renaissance are just two organizations that are currently known. Spark already has more than 70 members, while Renaissance is an unknown number.

There are quite a few people in this park. Apart from those who have unfortunately died, there should still be some left, such as over by the pavilion.

Xinghuo is also deliberately searching for survivors, so their number should increase significantly in the end.

Sooner or later, someone will come to search the square.

Judging from previous interactions with Liu Yuan and the other two, the people in this organization are not very friendly.

Therefore, the protection of the shelter still needs to be considered.

This issue also needs to be considered by the pavilion, but for them, Lu Yuning is more concerned about the stay or departure of several key figures.

In the past, it was mainly Xu Qi, so Lu Yuning's decision to invite Xu Lele into the team was a crucial one, and Xu Qi could also be bound over.

As for Chen Hong, it would be best if he could be brought over. It would be a shame if he didn't want to join, but his abilities weren't particularly crucial to Lu Yuning and the others. Lu Yuning didn't know much about Chen Hong. He supported Xu Qi but rarely interfered with her ideas, and many of his actions seemed to be spontaneous.

In addition to Chen Hong, there are now two more people with special abilities. Among them, Xu Ting is a very important person to them, and they cannot let her go to Xinghuo under any circumstances.

Fortunately, she has a good relationship with Xu Qi, which is also a key point.

In short, these are some of Lu Yuning’s thoughts that have always been in his mind.

Pull your thoughts back.

He wanted to move things up the tree, and he actually had two purposes.

The first one is of course to hide it. It is best if you can prevent the other party from finding it. If they find it, it will not be a good thing and there is a high probability of a conflict.

Judging from the combat effectiveness of Liu Yuan's three-person team, if there is a real conflict, they probably won't have an easy time.

Of course, although there are many of them, there is also a certain proportion of people with special abilities, and those with combat abilities should be even fewer.

Even if they come out in full force, there is still room for maneuver.

So the second purpose is naturally protection. Since I can't win, I will protect myself well, stay indoors, and then rely on buildings and facilities to fight back.

Under this premise, some production equipment and survival reserves must be protected.

Otherwise, everything will be destroyed and you will just be sitting there waiting to die.

Lu Yuning briefly explained the above idea, and everyone understood it.

"So the next thing is to do a good job of concealment and protection. On this basis, we need to research some weapons. Of course, these are also some of my ideas and plans. These things are not so urgent at the moment. The main thing right now is to get the water tank ready first." Lu Yuning said.

Everyone nodded and had a preliminary understanding of what would happen next.

Since we want to build a water tank high up on the tree trunk, we need to choose a location.

Their current residence is 30cm from the ground, and considering future expansion, 1 meter of space can be reserved.

Then it is better to choose a location of the platform about 2 meters above the ground.

This distance is already very high. Even before it was reduced, it was still a height that required looking up.

By comparison, a distance of 1 meter has the same visual effect as 100 meters before, which is about as high as a 30-story building.

2 meters already feels like reaching the sky for them, and their vision is a little blurry. Of course, this is just their visual perception.

In fact, climbing a 2-meter-high place is now much easier than climbing a 200-meter-high building in the past.

Once the location was confirmed, Lu Yuning began to prepare.

Of course, Wu Xiao, Lu Yuning's personal backpacker, also went up with them.

Since the current main purpose is to build the water tank first, the envisioned large platform can be placed first. We just need to make a fulcrum to put the water tank on it.

However, this thing cannot be taken lightly, as the final volume of the water tank is not small, and the fulcrum must first meet the weight requirements.

Based on this premise, Lu Yuning came up with a plan.

You still have to dig a hole in the tree, which has two uses.

First, the excavated wood chips can be used as materials, otherwise it is difficult to transport the materials up from the ground.

Secondly, the dug tree hole can be used as a slot, and based on this, the support point of the aerial platform can be extended from the socket, so that there will be a stronger force point.

Later, it was expanded on this basis.

Lu Yuning has also thought of a way to expand.

If the building is to be expanded horizontally, a bracket must first be built under the far end of the wooden board to support it and ensure the load-bearing capacity.

Similarly, you can splice the far end wooden board to the current wooden board using the slot method.

But a better way is to build a fence centered around the tree trunk.

After one circle is completed, if you want to expand it, you can continue to dig holes upwards and stack them up.
