"It's indeed cooler." Li Wenxi nodded, then smiled, "Actually, it doesn't matter if it's hot, just pour a basin of water on it! The main reason is that it's uncomfortable on the road. The saltpeter mine is at least three kilometers away from my tree house. It's too hot.

But I can’t get past it!”

"I'll be with you." Xu Xin stood up, "How about I go to the saltpeter mine and place a coordinate there."

When he had enough materials before, he made five more coordinates as backup.

It just comes in handy now.

"Yes!" Li Wenxi's eyes lit up and she patted his arm, "You are so smart!"

If coordinates were a scarce commodity for them before, now they are somewhat expensive consumables.

After all, the coordinates are made using blue-level materials, and blue-level materials are not scarce for them now.

Therefore, it is acceptable to put coordinates for a mineral point.

In this way, if the survivors in charge of mining want to mine, they don't have to trek through the scorching heat and can directly enter the cool mine.

"You are a little stupid." Xu Xin pinched her face and smiled, "Then I will go over and place the coordinates first, and then you can bring the others. Where is the location of the mine?"

"I'm not stupid!" Li Wenxi slapped Xu Xin's hand away, "I'll go with you, I can't explain clearly."

As soon as he left, Xu Xin immediately took Silver King down to the tree house.

Coco didn't want to go out for the first time, but Xu Xin dragged her out anyway.

With this little guy by his side, he can truly feel at ease.

When we arrived outside the tree house, we felt a rush of hot air.

"Wow...!" Feeling the heat, Li Wenxi suddenly looked bitter.

There is a huge temperature difference between the inside and outside of this house!

The current indoor temperature is maintained at around 25 degrees under the influence of blue saltpeter.

And outside the house...

It's clearly over forty degrees now!

The temperature is rising too fast!

"Hey..." Coco lay on Xu Xin's shoulder, drooping her limbs and big tail, not wanting to move.

Silver King also looked a little listless.

It's so hot outside, it really makes you feel dizzy!

The water level in the pond he dug outside the tree house has dropped significantly in less than an hour!

This pond is connected to the lake, and the water level in the pond has dropped, which means...

He looked towards the lake.

Above the lake, there is obviously steaming water.

but……

There were no clouds in the sky, and the blue sky was extremely clear.

There is no sign of any rain.

"...Will there be another severe drought?" Xu Xin's pupils shrank slightly.

In his original world, heat was usually accompanied by heavy rain.

In addition, the motherland's South-to-North Water Diversion and other projects ensured that the whole country would not be short of domestic water, so he did not have much idea about drought, so he did not notice it immediately.

but now……

Xu Xin frowned slightly.

This must be noted!

He sent a message directly to the alliance channel.

"Everyone, be careful to store water. In this weather, there may be a drought."

"Drought?" Li Wenxi also noticed this, "Yes, it is indeed prone to drought. But... we can't have all the lakes dry up, right?"

She pointed to the lake road which was still covered with a thick layer of ice a few days ago.

"No matter what, you still have to prepare in advance."

Xu Xin didn't think that his lake would dry up completely. After all, he knew how deep the lake was.

If it weren't for the fact that it was a freshwater lake, he would have suspected that the lake was connected to the sea.

but……

Most of other people's treehouses are by streams.

Judging from the speed at which the water level of the lake here is falling...

The possibility that the stream will dry up is very high!

He immediately contacted several people on his side and asked them to get more water now.

Then, he and Li Wenxi teleported to her tree house.

He turned around and quickly found the saltpeter mine under Li Wenxi's guidance.

The entrance to the mine is not big, but it looks like it was not dug by herself, but a naturally formed entrance to the mine.

In the mine, there was actually a hint of coolness emanating from it.

"Hey!" Coco felt the coolness and immediately jumped off Xu Xin's shoulders and ran into the mine.

Silver King stuck out his tongue and gasped, wanting to enter the cave quickly.

"That was the exit for exploring the underground city at that time." Li Wenxi pointed in one direction, "I came out of the underground and discovered this cave. I went in out of curiosity and took a look, and found saltpeter."

"...You are so lucky."

"Come in, let's put the coordinates inside, there is a suitable location inside!"

Indeed, it would be safer to put the coordinates inside.

Don’t worry too much about coordinates being destroyed.

Entering the mine, I suddenly became enlightened.

The entrance to the mine is small, but the inside is huge.

Fortunately, this cave is not deep, only thirty meters deep, and traces of digging can be clearly seen on the surrounding walls.

"This place is surrounded by saltpeter mines." Li Wenxi walked to the wall, took out a pickaxe and knocked on it.

Then he picked up one of the broken stones: "Look."

"It seems that the saltpeter reserves here should be quite large." Xu Xin nodded.

He found a flat location, put down the coordinates, activated them, and connected them to Li Wenxi's coordinates.

"That's enough." He patted the dust on his hands and said, "Let's go back."

"Hey!" Coco, who had been wandering around in the mine, climbed onto Xu Xin's shoulder.

The two returned directly to Li Wenxi's tree house through the coordinates.

Li Wenxi immediately summoned everyone and teleported over to mine the saltpeter mine.

Xu Xin returned to her tree house.

The air is a bit hotter again.

The temperature continues to rise.

Wearing the steel armor, he felt like he was sweating profusely.

At this temperature, we really can’t stay outside for much longer!

It’s easy to get heatstroke!

"You're back so soon." Lou Fei'er was about to return to her tree house when she saw Xu Xin and said in surprise, "We haven't gotten much water yet."

There seemed to be nothing unusual about her, she didn't even sweat.

This temperature is indeed nothing to her with a mutated physique.

Ma Hongwei and Zeng Tao were still getting water from the pool next to his tree house.

These two people also looked completely unchanged.

...The mutated physique is really good.

Xu Xin sighed.

……etc!

If the scorching heat has no effect on Lou Feier and the others who have mutated physiques...

That mutated creature...!
