This was the most reasonable explanation he could think of.
High temperature will accelerate the consumption of saltpeter, which has been proven by comparing Qi Xuefei's cultivation room.
"This..." Li Yajun fell into thought.
"It was hot again last night?" Li Wenxi was a little surprised, but then nodded. "That must be the case. Otherwise, if Yajun was so careful, this wouldn't 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 Li Yajun fell asleep at two o'clock in the middle of the night to the time of sunrise, the temperature should have been dropping continuously.
According to common sense, there should be no problems with the three pieces of blue-grade saltpeter she prepared.
However, there are too many things in this world that go against common sense.
They were indeed wary of what might happen at night, but including Xu Xin, they all felt that even if there was danger at night, it would only be something like an invasion by mutant creatures.
But I didn’t expect that it might be a high temperature late at night!
No one expected such high temperatures at night!
"That's the most likely possibility," Li Yajun agreed. "Only in high-temperature environments will saltpeter be consumed too quickly. But...why does the temperature soar in the middle of the night when there's no sunlight?"
She was still very confused.
"There's no need for so many whys in this world." Li Wenxi felt that even considering such things was pointless. "Then why do you think it was minus 20 or 30 degrees Celsius one day, and then soared to 40 or 50 degrees Celsius the next?"
"This..." Li Yajun was speechless.
Indeed, it is really difficult to reason in this world.
"...But there were signs of that," Xu Xin shook his head. "Even in this world, unexpected events don't occur without reason. The current high temperature is clearly due to the sunlight. I don't believe the person who brought us here can control the stars or the intensity of the sunlight. So, if I have to explain it, it's likely that there's something wrong with this planet's atmosphere."
The atmosphere is a planet's life-protecting umbrella that absorbs and retains heat, preventing a planet's temperature from becoming too high or too low.
On Earth, in places with high altitudes and relatively thin air, the temperature difference between day and night is much greater than that in places with low altitudes. This is also because of this.
Moreover, the sunlight in high-altitude areas is particularly strong, and the skin of people from high-altitude areas is usually darker.
Therefore, the problem now is most likely that something has happened to the atmosphere, causing some problems, which is why today's sunlight is so strong and the daytime temperature is very high.
Although it is quite outrageous, at least it can be done. After all, haven't humans on Earth created several large holes in the ozone layer?
But...what happened at night?
Did the temperature at night really rise suddenly?
Not only did it not decrease, but it increased?
hateful……
His tree house has a constant temperature system. As long as the windows are not opened, it will not be affected by the temperature outside. This made the survivors living in his tree house, including himself, unaware of anything last night.
They just felt like they had an ordinary night.
But...if the temperature suddenly soared again last night as he guessed, then the tree house without a constant temperature system would probably have problems like Li Yajun's.
If those people were able to survive, someone must know something.
But now the channel systems are blocked, and he can't get any information from the regional channels or the world channels.
Everyone around him lives in a tree house with a constant temperature.
Even Ji Chaoyang, who paid close attention to environmental changes every night, didn't notice anything last night.
Xu Xin narrowed his eyes slightly.
What happened last night must be clarified.
This abnormal phenomenon at night might be the breaking point of this hot summer!
Moreover, they don’t have any other direction to work towards now. After the hot summer, the mysterious voice has not appeared once until now.
"I'm going to the other people's tree house area. What are you going to do? Will you come with me, or..."
"You go ahead. I'll stay here with Yajun to rest for a while," Li Wenxi said. "Besides, I need to check out the smelting room. Come back and pick us up when you're done."
"Let's go to the smelting room now. Isn't it hot?"
"I have to go even if it's hot, but the smelting room is hot anyway. I'm used to it."
After coming out of Li Wenxi's tree house, Xu Xin directly activated the portal and first arrived at Wen Guixin's place.
Coincidentally, Wen Guixin just swung down from the tree house.
She looked anxious at this moment. When she saw Xu Xin, she was immediately startled and looked alert: "Who are you?"
Xu Xin was now completely wrapped up, with only her eyes exposed, so she naturally couldn't tell who it was.
"It's me, Xu Xin!" Seeing that she was about to draw her weapon, Xu Xin quickly explained.
"Xu Xin?" Wen Guixin recognized his voice and was a little surprised. "Why are you dressed like this? Are you planning to rob someone? But you've come just in time. Something's wrong here! It's just... come to my tree house first. It's too hot outside!"
Arriving at her tree house, she began to briefly describe what happened that morning.
It turned out that someone in her tree house had gotten up early, walked to the window and looked at the rising sun outside.
The result is predictable.
The man's scream woke up most of the people in other rooms. Then someone got up in the morning as usual to look out the window, and it happened to be the sunny side, so he was injured again.
