Doomsday: Humanity shrinks 100 times

Chapter 81 Productivity Ceiling

There are still several issues regarding the construction of the entire water supply system.

The first is the construction of the water tank, which has basically been completed for the most part. The platform for holding the water tank has been built, and Lu Yuning can complete the remaining work in a short while.

The second is the pipe connection work from the water tank to the accommodation area, which includes laying the pipes and setting the valves.

The third is the laying of pipes from the water tank to the steam pump, which is the water inlet of the water tank.

The fourth is the laying of the water inlet pipeline from the steam pump to the river.

In short, Lu Yuning’s main work from now on will focus on the production and laying of pipelines.

Because a lot of pipes are used, Lu Yuning has already confirmed with Zhang Xinyue in advance whether the materials are sufficient.

After some calculations, Zhang Xinyue concluded that there was nothing to worry about based on their current material reserves.

Of course, the diameters of these three pipes are not the same. The one laid towards the living area is thicker and will then be diverted to various facilities.

The pipes for the remaining two routes can be of the same diameter.

However, there is a problem in this laying process, which is the placement of the pipes.

This is divided into two parts, pipelines No. 2 and No. 3, and pipeline No. 4 leading to the river.

The problem with numbers two and three is the way they are laid.

The main consideration is whether there will be concealment problems if the pipeline is placed outside.

These two long pipes are easy to find from top to bottom.

The previous sewage pipe had the same problem, and Lu Yuning has already considered re-processing it.

So Lu Yuning wanted to simply dig a hole from top to bottom in the outermost area of the trunk to lay the pipes.

This not only solves the concealment problem, but also reduces the difficulty of laying.

Because of their height, it is a very difficult operation to fix two nearly three-meter-long pipes on the tree trunk in the air.

If you drill a hole in the tree, you don't have to worry about this problem.

Just lower the pipe down the tree hole.

Of course, the disadvantages are obvious, and it’s still a matter of workload.

After thinking about it for a while, Lu Yuning decided to use this solution. The advantages are more obvious, and the workload can only be converted by time.

This process is actually quite simple. Lu Yuning's ability has a control distance. As long as the bark is separated from it, he can crush the tree trunks within a certain range.

He just needs to choose a route and drill a small hole.

In this way, the laying plan for pipelines No. 2 and No. 3 was determined.

They had also discussed the laying method of Pipeline No. 4 before.

The problem with pipeline number four is that it passes through an area of dense weeds.

This area left a big shadow on Lu Yuning, as there might be dangerous creatures like spiders in it.

So it is a bit difficult to pave it.

Everyone thought of several methods. One was to make a tubular passage like before. It didn't need to be too strong, as long as people could walk inside it.

Then through this pipe, lay the plastic water pipe.

This has the advantage that the outside of the pipe is protected and there is no need to worry about it being damaged by insects or other creatures.

The disadvantage is naturally that the laying efficiency is relatively slow and the risk level is still high.

The second method is to let Xu Qi's chipmunk help with laying the floor, which is the most efficient.

Finally, there is another type. Although it has the best effect, the strongest concealment, and the best protection for the pipes, Lu Yuning still ruled it out first.

The plan is to dig a hole from underground to the river.

Although it is a perfect laying method, the workload is almost terrifying. It is different from digging a hole in the tree trunk, because the crushed wood material in the trunk can fall out of the trunk by its own weight.

However, if he dug a hole in the ground, although Lu Yuning could crush the soil, he could not make it disappear directly.

The soil after being crushed is actually just a little softer, but it still needs to be dug, and the soil will eventually have to be moved outside.

Although Wu Xiao's special ability can be used, the distance from the tree trunk to the river is 6 meters, which is still a difficult task.

In the end, everyone decided to let Xu Qi help, and then hide the exposed pipes near the tree trunk.

As for the durability of the pipes, we will not consider it for the time being. At worst, we can just make another one later. In fact, they don’t pump water very often.

When their abilities grow, we can consider laying a stronger new one.

After Lu Yuning confirmed the laying routes of pipelines 2 and 3, he began to dig through the laying routes.

This is a rather boring job and can only be done bit by bit. Wu Xiao can't help much.

Two hours later, a feeling of dizziness came over him again, and Lu Yuning finally dug through the paved route.

After resting for a while, he looked at the sky and did not dare to delay any longer, so he officially started the pipeline laying work.

The laying process is relatively simple.

All Lu Yuning had to do was make the pipes and insert them into the laid lines.

This part requires Wu Xiao's participation. He needs to prepare the materials and place them near Lu Yuning.

"Phew, so tired"

Lu Yuning and Wu Xiao jumped down from the tree trunk, both feeling exhausted.

Everyone immediately gathered around.

The people standing on the ground could only vaguely see a large bulge above the tree trunk.

It seems that even if it is not covered up, it is not easy to find, and it is quite concealed.

You have to know that they only discovered a faint bulge after they already knew there was something on it.

It is difficult for a normal shrunken human to imagine that it is a man-made structure.

Even if they notice it, most people will probably think that it existed before the end of the world.

"Thank you for your hard work. Are you done?" Zhang Xinyue asked.

"It's done. All that's left is to wait for Xu Qi to come tomorrow and lay the pipes to the river." Lu Yuning replied a little tiredly.

Lu Yuning now vaguely realized a problem. Although his special ability has strong capabilities in construction.

But there are many things that only he can do. Even if he is very capable, he will be unable to handle them all. This is the upper limit of their productivity.

This situation will not improve with the increase in manpower. In the future, we will still have to rely on ourselves to build facilities, which is a serious problem.

For example, in the construction of this water system, 90% of the workload was on Lu Yuning, and no one else could help at all.

However, there is still no solution to this problem at present, but it still reminds Lu Yuning that they need to find some more talents.

Let’s see if there are some useful abilities that can solve this problem.

Maybe others also have the ability to build.

Although searching for someone less than two centimeters tall in a park is almost like looking for a needle in a haystack, they still have Zhang Xinyue's special ability, so they can still give it a try.

He finally realized why Xinghuo was looking for people with special abilities everywhere. It was probably because of this problem.

So maybe they had already spotted the problem?

That is to say, Xinghuo’s current level of development may have surpassed Lu Yuning and the others.
