Doomsday: Humanity shrinks 100 times

Chapter 144 Destiny and Choice

It took Lu Yuning a lot of time to make the thermometer, and he finally made one that was about four or five centimeters long.

The temperature sensing device is about the thickness of an arm and is actually the size of a toothpick.

It looks similar to a normal thermometer, except that the liquid inside is transparent and there are no scales on the outside.

After Lu Yuning carefully carried it outside, the liquid inside shrank visibly due to the cold.

It seems to be relatively successful.

After the core temperature sensor is made, it is time to start assembling the balancing device.

The focus is mainly on the construction location and the production of gear transmission.

Since the actual weight of the temperature sensor, that is, the thermometer, is not large, the friction of the shaft part cannot be too large.

In short, after being reduced in size, many mechanical devices have problems with friction.

Considering the impact of opening and closing the door on the thermometer, Lu Yuning decided to set up a separate room as a temperature monitoring room.

Of course, the distance cannot be too far from the heat source of the floor heating, and the force must eventually be transmitted to the switch of the heating device through a mechanical linkage.

The rotation of the thermometer drives the gear, which then converts the force into a horizontal direction through three connecting rods.

This is probably a device like this. It is actually just a very simple transmission device, but it is much more difficult to make than you might imagine.

The main reason is that gears are difficult to make, even though Lu Yuning's ability has now improved to the point where he can control metal.

However, it is still difficult to make something with such high precision.

Gears actually require very high precision.

It is different from the winch made in the forest before, although it also contains the concept of gear ratio.

However, it is actually achieved through the ratio of the hand-turned wheel and the shaft, and no real gears are made.

So this temperature control device was Lu Yuning’s first attempt.

If the serrations are not balanced enough, there will be problems in use.

Generally, gears are made by professional machine tools, and mechanized devices are used to ensure the quality of the parts.

Even so, there is still a high scrap rate in the production of gears in industry.

What’s more, it is made manually.

This problem will always accompany Lu Yuning's special abilities. Even if his abilities become stronger and stronger, the issue of precision will always be a bottleneck.

I don’t know if there will be a way to solve it in the future, but now I can only achieve it bit by bit through patience.

Since the failure rate is relatively high, you can only do it a few more times until you are satisfied.

Finally, despite feeling a little dizzy, Lu Yuning managed to make two gears, one large and one small, that fit together well.

He thought about it and made another mold using these two gears. This way, it would be much easier to make it next time.

A group of people started the final construction of the temperature control device with two gears.

In the end, it took Lu Yuning a whole day to finally fix this small temperature control device.

Looking at the balancing device parked in front of them, everyone was a little curious.

"Will it turn if the temperature changes?"

“It looks like a big seesaw.”

Everyone started discussing it.

"Do you want to try it?" someone suggested.

Lu Yuning nodded. This thing naturally needed to be tested, and he had prepared it in advance.

Take out a piece of insulated aluminum sheet and start heating.

As the temperature in the room rises, the alcohol in the thermometer begins to expand and the device begins to slowly tilt.

This drives the gears to rotate, and eventually the connecting rod slowly rises.

Then Zhang Qian isolated the heat again, the indoor temperature dropped, and the balancing device slowly returned to normal.

With this, the core temperature control device is complete, but it's not yet time to turn on the floor heating. It can be officially used once the temperature drops completely, and the parameters will definitely need to be readjusted at that time. Although this device is time-consuming and labor-intensive and not particularly sensitive, the production process is a kind of accumulation.

On the road to technological advancement, there must always be some basic production capabilities.

The development and construction of the shelter is still in full swing.

However, Lu Yuning suddenly felt uneasy recently.

It’s hard to describe this feeling. It’s like a shadow covering my heart, and I suddenly feel lost as if I’m at a fork in the road.

It's like something deep down in my heart is stirring my emotions.

As this feeling grows stronger, the shelter welcomes an uninvited guest.

The last time he saw a chipmunk running towards him by itself was when Xu Qi was sick with a cold.

But last time it was Xu Lele who came along.

However, this time it was the giant rat that came running over by itself.

Lu Yuning sighed inwardly. It seemed that something had happened to Xu Qi again, and it was probably quite serious.

The strange thing is that I seem to have been able to sense my emotions in advance these days. Could this be a kind of perception ability after awakening my supernatural powers?

This explanation is a bit exaggerated.

Many people in the square have seen the arrival of the chipmunk.

The chipmunk was unable to communicate with everyone, but it did know Lu Yuning.

After coming, it just lay beside Lu Yuning, curled up with its tail spread out.

"Xiao Jin!" When Xu Lele saw the chipmunk coming, he hurriedly walked up to it and touched its head affectionately.

Then she immediately thought of something and said, "Where's my sister?"

The chipmunk couldn't speak either, it just nudged her.

Although Xu Lele is not very old, he is still quite sensible. After a slight pause, his face immediately turned pale.

At this time, everyone looked at each other, obviously able to guess what this situation meant.

Zhang Xinyue frowned and whispered to Lu Yuning, "Is there something wrong over there?"

Lu Yuning nodded: "It's probably true."

Judging from the chipmunk's appearance, it seemed to be frightened by something and must have run over on its own initiative.

In other words, Xu Qi had no way to communicate with it at that time.

Then there are only two possibilities: either he was killed or he was controlled.

However, since the chipmunk ran over, it should be looking for Lu Yuning for help, so the latter is more likely.

The only thing that can be imagined is that they had a conflict with Xinghuo.

At this time, everyone was in the dimly lit conference room except Zhang Qian and Xu Lele.

Since it was related to Xu Qi, it was better to prevent Xu Lele from getting involved. It was inevitable to be anxious, so Lu Yunnan had to ask Zhang Qian to calm her down.

The remaining few people gathered together mainly to make a decision quickly.

Should I go to the pavilion or not?

Lu Yuning himself was also a little conflicted. The last time he rescued Han Yingying, it was motivated by profit.

Her special ability is the key factor in Weiguang's future development, and the initial decision was to rescue people by stealth, which was true, although it ended up in a dangerous situation.

But over at the pavilion, Xu Qi was the only one who had a good relationship with everyone else, so morally speaking, he should be saved.

However, they had to consider the collective. For Liu Rui and his friends, the pavilion had nothing to do with them.

Even though we are a collective, it would be selfish to drag them all into this.

So if you are rational, you should not get involved in this mess.
