Chapter 492 The strange situation at night (4600 words)

Beside, the two people except Xu Xin were already sweating profusely.

"Well...it's so hot. Let's cool down the tree house." Li Wenxi wiped the sweat on her forehead and said.

"Ah..." Xu Xin suddenly remembered that the temperature in the room was not something they could bear for a long time.

No normal person can bear the temperature of forty-five or six degrees in the room.

At this time, the blue saltpeter in the basin has completely precipitated and turned into powder.

As long as water is added to it, the surrounding temperature will drop.

Looking at the blue powder, Xu Xin suddenly had an idea.

He had been using blue-grade saltpeter before. In his tree house, the blue-grade saltpeter used for cooling was consumed very slowly. So far, not one piece of blue-grade saltpeter has been completely consumed, and none has even shrunk significantly.

Therefore, this was the first time he saw the powder precipitated after dissolving blue saltpeter.

If it were this kind of powder...

Compared to stone saltpeter, will this powder dissolve in large amounts instantly, absorb a lot of heat, and cool down like crazy?

It's really possible.

...Don't use this now, this thing may be useful later.

Xu Xin put away the basin, took out another basin of water, and threw two pieces of saltpeter into it.

The surrounding temperature began to slowly drop.

At this time, after taking a pill, he was peeling a blue-level orange and had almost recovered. He was looking at Li Wenxi with his eyes.

"Wen Xi, how do you feel today..." She looked at Li Wenxi and felt something was wrong. Some thoughts in her mind even made her blush.

"Ah? Ah...hehe!" Li Wenxi chuckled, "How about it, do I make people want to get close to you today?"

"Well, it's true." Li Yajun nodded honestly.

"Humph, because I have..." Li Wenxi explained to her.

"How can it still be like this!" Li Yajun was very surprised.

"Okay, you can talk about these things later. Has anything happened around here during this time?" Xu Xin asked Li Yajun.

Li Yajun shook his head and said: "Nothing happened. I didn't go to bed until about two o'clock in the middle of the night last night. Before that, nothing really happened. But..."

Li Yajun looked at the basin, a trace of doubt flashing in her eyes.

"What's wrong?" Li Wenxi asked.

"Well... I came here around ten o'clock last night, selected a small room like your bedroom, and used two pieces of blue-grade saltpeter to cool it down. It wasn't until about two o'clock in the morning that the two pieces of blue-grade saltpeter were exhausted.

"

As she spoke, Li Yajun took out a basin of somewhat turbid water from her backpack, which was water in which saltpeter was dissolved.

"Oh?" Xu Xin heard the meaning of her words, "In other words, these two pieces of blue-grade saltpeter have been working from ten o'clock last night to two o'clock in the middle of the night, and they lasted four hours?

"

"I persisted for so long. I thought I had to change it every two hours." Li Wenxi was a little surprised.

Qi Xuefei told her that in order to maintain the temperature of her culture room, it needed to be changed every two hours.

However, that's because Qi Xuefei's culture room is very large, and it only needs to be changed every two hours when the temperature reaches 60 degrees at noon.

This small bedroom of more than ten square meters is indeed enough to change every four hours at night.

"Yes." Li Yajun stuffed a piece of orange into her mouth, chewed it, and thought about it. She said with some confusion, "It's not six o'clock in the morning yet? It's less than four hours before I go to bed.

?Furthermore, in order not to cause problems due to too little saltpeter, I put three pieces of blue-grade saltpeter into the water, but..."

After hearing this, Xu Xin finally understood what was wrong.

The time consumed by the saltpeter does not match up.

From ten o'clock to two o'clock in the middle of the night, two pieces of blue-grade saltpeter kept the temperature of this room constant for four hours.

The first time he sent a voice message to Li Wenxi's tree house, it was only a little after five o'clock.

At that time, Li Yajun could not wake up and could not connect to the voice call.

From two o'clock in the middle of the night to five o'clock in the morning, this is only three hours.

Moreover, Li Yajun wouldn't suffer from heatstroke and be unable to wake up as soon as the room temperature became hot, right?

This will take some time to settle.

In other words, the three pieces of blue-grade saltpeter used later were consumed in just two hours.

……Why?

Li Wenxi also reacted at this time: "Huh? This is indeed the wrong time... But let me tell you, how could someone as careful as Yajun have problems like this?"

She put her arms around Li Yajun's shoulders: "I wrongly blamed you!"

Li Yajun shook his head: "It's indeed my problem. I didn't think well. If you hadn't come here, I'm afraid..."

But she also had some doubts.

Why?

She obviously put in an extra piece.

"It's not because the saltpeter is big or small, and the saltpeter time is different, right?" Li Wenxi speculated.

Li Yajun shook her head: "No, although there are indeed big and small blue grade saltpeters, the difference is very small and can basically be ignored. And didn't I put in an extra piece?"

"Then... if you add another piece, it will dissolve at the same speed, but it will just make the temperature lower?" Li Wenxi argued.

"Even so, it won't be so different." Xu Xin shook his head and rejected the idea.

"Well...it's true, there's a huge difference..."

"...My idea is that during the period when you were asleep, there was a period of continuous high temperature. Therefore, even though you put in an extra piece of saltpeter, it was still consumed early." Xu

Xin speculated.

This was the most reasonable explanation he could think of.

High temperature will accelerate the consumption of saltpeter, which has been proved by comparison with Qi Xuefei's cultivation room.

"This..." Li Yajun fell into thinking.

"It was high temperature again last night?" Li Wenxi was a little surprised, but then nodded, "That should be it, otherwise, if Yajun is so careful, this situation would not have happened. This kind of weather is too troublesome...

"

Normally, the lowest temperature of the day is before sunrise.

In other words, from the time when Li Yajun went to bed at 2 o'clock in the night until sunrise, the temperature should have been continuously dropping.

According to common sense, the three pieces of blue-grade saltpeter she prepared should not cause problems.

However, there are too many things in this world that go against common sense.

They were indeed wary of what would happen at night, but including Xu Xin, they all felt that even if there was danger at night, it would be like an invasion by mutant creatures.

But I didn’t expect that it might be very hot late at night!

No one expected the high temperature at night!

"This is the most likely possibility." Li Yajun also agreed with this view, "In high-temperature environments, saltpeter will be consumed too quickly, but... why does the temperature soar in the middle of the night when there is no sunlight?"

She was still very confused.

"There are so many reasons in this world." Li Wenxi felt that even if she considered this kind of thing, it would be useless. "Then what do you think, why was it still 20 or 30 degrees below zero one day, and soared to 40 or 50 degrees above zero the next day?

Woolen cloth?"

"This..." Li Yajun was speechless.

Indeed, it is really difficult to speak truth in this world.

"...But that's also a sign." Xu Xin shook his head and said, "Even in this world, changes will not happen for no reason. The temperature is too high now, obviously because of the sunshine. I don't think it will bring us to

People here can control the stars and the intensity of sunlight, so if we insist on explaining it, there may be some problems with the atmosphere of this planet."

The atmosphere is a planet's life-protecting umbrella, which can absorb and preserve heat and prevent a planet's temperature from being too high or too low.

On the earth, in places with high altitudes and relatively thin air, the temperature difference between day and night will be much greater than in places with lower altitudes, and it is precisely because of this.

Moreover, the sunlight in high altitude areas will be particularly strong, and usually the skin of people from high altitude areas will be darker.

Therefore, the problem now is probably that the atmosphere has been manipulated and some problems have occurred, which makes the sun shine so fiercely today and the temperature during the day is very high.

Although it is quite outrageous, at least it can be done. After all, haven’t humans on the earth also created several large holes in the ozone layer?

But...what happened at night?

Did the temperature really rise suddenly at night?

Not only did it not decrease, but it actually increased?
