Doomsday: Humanity shrinks 100 times

Chapter 86 Trial Run

Lu Yuning squatted down and touched the stone material on the river bank with his hands.

He felt its hardness, then activated his supernatural power, crushed a small stone and took it down.

"Okay, that's easy," Lu Yuning said to himself.

Since we can dig up the stone, there is no big problem.

He was familiar with the work of digging holes. He just had to make a hole and then bury the pipes in it.

Xu Qi was a bit bored and couldn't help much, so he could only stand by and watch him work, chatting with him from time to time.

"Your ability is truly omnipotent."

Without even looking up, Lu Yuning casually replied, "Yours isn't bad either."

"We? I used to think so, but compared with you guys, it seems a bit useless." Xu Qi was a little discouraged.

Lu Yuning said as he worked, "Superpowers actually have their own advantages. It all depends on how you use them. Another point is that you must use your superpowers frequently. The more you use them, the faster they will improve. Once they reach a certain level, you will unlock some special ways to use them."

"Both have advantages? What about you? I feel that Xu Ting has no advantage compared to you." Xu Qi obviously didn't believe it, and silently compared Lu Yuning and Xu Ting.

"Well, let me give you an example. Take my construction ability, for example. With the same piece of material, I can crush it and reassemble it to make whatever I want."

"Yeah," Xu Qi listened carefully.

"What if Xu Ting handles it? If she's strong enough, she can soften the material to a point where we can handle it with our current strength. If the material is tough enough, like plastic, we can use the softened plastic to shape something."

"Then what? Don't we still need more manpower?" Xu Qi was puzzled.

"Okay, with this premise, let's assume you have enough people, hundreds of them. Hundreds of them are making an item at the same time, and each person is only responsible for processing a certain part of the materials. Wouldn't that be a bit more efficient?"

Xu Qi nodded and thought about it and it seemed to be the case.

Lu Yuning continued, "If the item being crafted is enormous and I can't complete it all at once with my abilities, then the ultimate productivity limit is actually manpower. However, my abilities can't provide efficient collaboration, and Xu Ting's advantages are even greater. Therefore, in certain scenarios, her abilities surpass mine."

Xu Qi's beautiful eyes lit up, and she finally understood.

"In short, think more about how to use your abilities," Lu Yuning concluded, and then stopped talking.

Xu Qi was lost in thought and stopped talking, as if he was thinking seriously.

……

"It's done, we can go back now." Lu Yuning clapped his hands, looking at the tightly buried pipes in front of him with great satisfaction.

As Lu Yuning finished laying the water pipe, the purpose of this trip was completed.

The water supply system is finally almost completed.

The two of them climbed back into the vehicle without delay and quickly headed back.

As soon as the two showed up, they were discovered by the people who had been waiting nearby for a long time and quickly came over.

"Okay?"

Lu Yuning said, "There are two pieces of news, one good and one bad. Which one do you want to hear first?"

Everyone was stunned. It seemed that this trip would have some twists and turns.

Several people actually discussed it seriously for a while, and then someone said, "Let's hear the good news first."

Lu Yuning nodded, then gathered his emotions, put on a serious expression, and said, "Well... after three days of hard work, I declare the water supply system complete!"

Everyone smiled and clapped cooperatively, the applause was enthusiastic.

"What about the bad news?" Zou Yunxin asked.

"bad news"

Lu Yuning used simple language to describe what happened in the grass area.

Hearing him say there were many spiders in the grass, everyone immediately stood further away, their gazes towards the grass becoming more cautious. "Should we take some precautions?"

"We definitely need to deal with it, but let's put it aside for now. Whether we're defending it or finding a way to eliminate it, we need to plan it out. Let's finish the current task first. Everyone stay alert and stay away from the bushes." Lu Yuning suggested.

Everyone nodded.

After learning that there were mutants nearby, the overall mood in the shelter became a little tense.

Everyone looked towards the grass area from time to time, always feeling that there was a group of spiders staring at them, and the more they thought about it, the more uncomfortable they felt.

Lu Yuning felt a little helpless, but she still had to tell everyone about this matter. Fear could also make people more vigilant.

However, the water supply system still needs to continue to operate. Once the water problem is completely resolved, we will consider the spider's nest.

The entire water supply system has been completed, and all that remains is to officially start storing water.

Although they had done some air intake and exhaust experiments on this steam pump before, they were still a little nervous when it came to this last step.

The heating process started again and all the exhaust valves were opened.

After a while, Lu Yuning saw water vapor continuously coming out of the vent, and with the help of Zhang Qian, he closed all the valves.

Then just wait for the device to cool down.

This time was still a bit long, so everyone had to wait patiently.

Lu Yuning touched the device and felt that the heat dissipation was almost complete.

He walked to the water inlet valve and reached out to press the disposable valve that had been treated.

They redesigned the valve and removed the rotating device. Opening and closing the valve depends entirely on Lu Yuning's special ability.

Fortunately, Lu Yuning brought back a lot of rosin from the forest today. I was worried about air leakage, but now it seems that the sealing is fine.

Lu Yuning's mind moved slightly, and he did not directly break the obstruction inside. Instead, he only made a slightly smaller water inlet hole to prevent the water inlet pipe from being flattened due to excessive pressure in an instant.

The pipe moved obviously, but the familiar sound of air intake did not appear.

When everyone was about to wonder, they heard the sound of flowing water coming from far away along the water inlet pipe.

Then the water inlet pipe shook slightly again, and then the river water was seen being quickly sucked into the steam pump along the pipe!
Cheers rang out. At this point, it could basically be declared that the steam pump was operating successfully.

Of course, this thing is not perfect yet. The final step of opening the valve to let water in still requires Lu Yuning to use his supernatural powers to complete it.

This method can easily lead to airtightness problems, and is actually a somewhat dangerous behavior if not performed properly.

If Lu Yuning did not operate it properly, causing air leakage at the valve, the instantaneous air pressure would directly crush him.

Therefore, this steam pump still needs to be modified later.

Zhang Xinyue also gave an idea. Since opening the valve requires a lot of strength, and considering their strength limit, it is definitely not possible to rely on manpower alone.

So we need to make a lever device to use the force to operate the water inlet valve.

Another advantage is that there is no need to worry about the container overheating, and the valve control distance can be extended.

Of course, this situation will lead to another problem: whether the valve shaft material can withstand such torsional force.

　Thanks to Forest Sky for the monthly ticket.

　　Thank you everyone for your recommendation votes.

　　Actually, when I was building this water supply system, I didn't expect so many problems to arise.

　　But when you think about it carefully, there are difficulties everywhere.

　　So readers who like to pay attention to details should be able to feel that I have actually been patching things up =_=.
