On the side, the two people except Xu Xin were already sweating profusely.
"Hmm... It's so hot. Let's cool down the tree house." Li Wenxi wiped the sweat from his forehead.
"Ah..." Xu Xin suddenly remembered that the temperature in the room was not something they could bear for a long time.
The temperature in the room is 45 or 46 degrees Celsius, no normal person can stand it.
At this time, the blue saltpeter in the basin has completely precipitated and turned into powder.
As long as more water is added, the surrounding temperature can be lowered.
Looking at the blue powder, Xu Xin suddenly had an idea.
Before, he had always used blue-grade saltpeter. In his tree house, the blue-grade saltpeter used for cooling was consumed very slowly. So far, no piece of blue-grade saltpeter had been completely consumed, and no piece had even shrunk significantly. Therefore, this was the first time he saw the powder precipitated after the blue-grade saltpeter was dissolved.
If it's this kind of powder...
Compared to stone-like saltpeter, will this powder dissolve instantly, absorb a lot of heat, and cause a rapid drop in temperature?
It's really possible.
...Let’s not use this for now, it might be useful in the future.
Xu Xin put the basin away, took out another basin of water, and threw two pieces of saltpeter into it.
The surrounding temperature began to drop slowly.
At this time, the one who had taken a pill and was now peeling the blue-level orange had almost recovered and was looking at Li Wenxi.
"Wenxi, 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, "So, do I make you want to get close to me today?"
"Yeah, a little bit indeed." Li Yajun nodded honestly.
"Hehe, because I have something today..." Li Wenxi explained to her.
"How can it be like this?" Li Yajun was very surprised.
"Okay, let's talk about these things later. Has anything happened around here during this period of time?" Xu Xin asked Li Yajun.
Li Yajun shook her head and said, "Nothing happened. I didn't fall asleep until around 2 a.m. last night. Before that, nothing really happened. But..."
Li Yajun looked at the basin, a hint of doubt flashing in her eyes.
"What's wrong?" Li Wenxi asked.
"Well... I came here around ten o'clock last night. I chose your bedroom, a small room, and used two blocks of blue saltpeter to cool it down. It wasn't until around two in the morning that the two blocks of blue saltpeter were exhausted."
As she spoke, Li Yajun took out a basin of slightly turbid water from her backpack. This was the water in which saltpeter had been dissolved.
"Oh?" Xu Xin understood what she meant. "So, these two pieces of blue saltpeter were working continuously between 10 o'clock last night and 2 o'clock in the morning, for a total of four hours?"
"You've been holding on for so long. I thought you only had to change it every two hours." Li Wenxi was a little surprised.
Qi Xuefei told her that in order to maintain the temperature in her culture room, she needed to change the temperature every two hours.
However, that is because Qi Xuefei's culture room is very large, and even at the highest temperature of 60 degrees at noon, the temperature needs to be changed every two hours.
For this small bedroom of more than ten square meters, changing it once every four hours is indeed sufficient at night.
"Yes." Li Yajun stuffed an orange slice into her mouth, chewing it while thinking, somewhat puzzled, "It's not even six o'clock in the morning yet? It's less than four hours since I went to bed. Also, in order to avoid problems due to too little saltpeter, I put three pieces of blue saltpeter in the water, but..."
After hearing this, Xu Xin finally understood what was wrong.
The time it takes for saltpeter to be consumed doesn't match.
From ten o'clock to two o'clock in the morning, two pieces of blue saltpeter kept the temperature of the room constant for four hours.
When he first sent a voice message to Li Wenxi's tree house, it was just after five o'clock.
By that time, Li Yajun was already unable to wake up and could not get through the voice call.
From two in the middle of the night to five in the morning, that's only three hours.
Besides, it’s not possible that Li Yajun would get heatstroke and be unable to wake up as soon as the room temperature became warmer, right?
This will take some time to settle.
In other words, the three pieces of blue-grade saltpeter used later were almost completely consumed in just two hours.
……Why?
Li Wenxi also realized at this time: "Huh? This time is definitely wrong... But, I was saying, Yajun is such a careful person, how could she get into trouble because of something like this?"
She put her arm around Li Yajun's shoulders and said, "I wrongly blamed you!"
Li Yajun shook her head. "It's really my fault. I wasn't thoughtful enough. If you hadn't come here, I'm afraid I would really..."
But she also had some doubts.
Why?
She clearly put one extra piece in.
"Could it be because the saltpeter is large and small, and the saltpeter time is different?" Li Wenxi speculated.
Li Yajun shook her head. "No, although the blue saltpeter does have different sizes, the difference is very small and can be basically ignored. Besides, didn't I put an extra piece in there?"
"Then... if you put one more piece in, the dissolving speed will be about the same, right? It will just make the temperature lower?" Li Wenxi argued.
"Even if that's the case, the difference won't be that big." Xu Xin shook his head and rejected the idea.
"Hmm... Indeed, the difference is too big..."
"...My idea is that during the time you were asleep, there was a period of continuous high temperature, so even though you put an extra piece of saltpeter, it was consumed early." Xu Xin speculated.
