"The Drought Demon is probably just approaching here, but the real distance should still be far away, otherwise it won't just be a rise in temperature."

He felt relieved, took a look at the experience of the safe house, and his face lit up.

"Finally full."

[(pseudo) portable safe house lv.1:6/5 (upgradeable)]

"upgrade!"

I saw a flash of light.

In less than a second, the upgrade is over.

[Portable safe house lv.2:1/10 (a portable house made of stacked wood, it can be used to shelter from wind and rain, and its safety is average)]

"The introduction has changed, isn't it fake anymore?!"

Yang Yuan hurriedly walked closer and inspected it carefully, and found that the original inlay openings between the modules seemed to have become some kind of mortise and tenon structure.

This kind of structure cannot even be dismantled by people who don't understand it.

"This... I can't take it apart, so how should I carry it with me?"

He circled around the safe house, inspecting it carefully, and found that the number of modules in the safe house had increased.

Many places were originally supposed to be a whole, but now they have become several parts.

"Is this change useful? Can it really become what I want? Press a certain button and it will shrink into a box or even smaller."

He thought with some anticipation.

But there are people inside now, so it’s not convenient to try.

"Now that I have some experience, the next upgrade will take five hours for two people and only three hours for three people."

Then wait until you upgrade again.

"Now my power armor can scan a hundred meters radius, and I can keep vigil without being outside."

Thinking of this, Yang Yuan immediately put out the bonfire, put on his power armor and entered his small cubicle, closed the door, sat down on the bed, and waited patiently.

During this period, he tried pressing the button on the wall, but found that the LED light above his head only had a very weak light and had no lighting effect at all.

It seems that without sunlight, this solar lighting will not be effective.

After an hour, the experience of the safe house directly increased by three points.

"As I guessed, the way experience increases is related to the number of people."

Yang Yuan remembered this. It seems that different items have different ways of gaining experience, and it is even related to the number of people.

Perhaps because he had been promoted to three levels in a row, his energy and energy had improved a lot, and he didn't feel sleepy very much.

At the same time, the monitoring room in the safe area five hundred meters away.

A group of people stared at the picture captured by the hot air balloon satellite with ugly expressions.

"Those Drought Demons have arrived seven hundred miles away and can already affect this place! They are still moving here. In addition, some female beasts nearby also have signs of mutation. There are so many of them that they can't be killed at all. It's no longer safe here.

Come on, Chief, do you want to evacuate?"

A soldier asked with a stern expression.

An old man standing next to him who was calm and self-confident pondered slightly, and then said in a deep voice: "Stop all construction work, drain all the underground water, and let the space carriers be loaded in. Make preparations for evacuation first, and evacuate early tomorrow morning."

"But is there still time tomorrow? The female beasts nearby may mutate on a large scale. By then, this area will be transformed into a furnace of heaven and earth, and ordinary people will not be able to travel for a long time." The soldier asked worriedly.

The old man said in a deep voice: "Let's use the rare item 'Teng Yun'. It just so happened that a large amount of groundwater was extracted this time, which is enough to last for a while."

The soldier perked up and asked hurriedly: "Do you want to inform the people now?"

"No, it's still too late. Let's wait until dawn. Let them have a good night's rest."

The old man looked very ugly. He had just settled down, but he was about to be on the run again.

But facing the kind of monster that can cause natural disasters, they have no choice but to retreat.

"By the way, some basic supplies will be sold to the outside world tomorrow morning. Those with super powers who have not joined the safe zone. Anyone who buys water should receive a cooler as a gift to prevent their water from evaporating." He added.

The soldier couldn't help but mutter: "If you ask me, those with superpowers who don't obey the arrangements should just be left to fend for themselves. They will cause trouble and waste resources while they are alive."

The old man glanced at him lightly, and he quickly shut up.

The old man gave a solemn lesson: "Before they commit unforgivable sins, they are still common people, and they are potential stocks that we need to unite and win over. Don't underestimate any superpower, our enemies are not just those who have reversed yin and yang."

Monster, don’t say such stupid things next time!”

"...Yes, Chief!"

…

Time passes.

When the sky outside turned a touch of fish belly white, the safe house experience was once again full.

Yang Yuan couldn't wait and chose to upgrade.

Two seconds later, the LED light above his head suddenly turned on, startling him.

Because the brightness of this LED light is already comparable to that of mobile phone lights.

Fortunately, Zhao Jiayan and Jiang Yiyi didn't turn on the lights in the cubicle next door, otherwise they would definitely be woken up.

"The brightness is okay!"

Yang Yuan stood up in amazement and left the safe house, looking at the information about the upgraded safe house:

[Solar integrated portable house lv.3:0/20 (portable safe house, built-in solar lighting, already has a certain degree of safety)]

"Name changed?"

Yang Yuan was slightly surprised.

At this time Zhao Jiayan and Jiang Yiyi woke up.

"Why is it so hot?"

Zhao Jiayan got up, fanned the wind with her hands, and asked doubtfully.

Suddenly she saw the bright lights in Yang Yuan's cubicle next door. She walked over to take a look in confusion and asked in surprise: "Why are the lights here so bright?"

Without waiting for Yang Yuan to answer, Jiang Yiyi climbed out: "Brother, it's so hot."

Yang Yuan also felt very hot, but when he saw that there was no movement in the safe area, he said patiently: "It should be the drought demon approaching here. Have you slept enough? If so, we will go to the safe area to buy some things. Maybe we will go to the safe area again."

I have to run for my life."

He remembered that the night before yesterday, the night when he first came to this world, the temperature was only seven or eight degrees late at night.

But now, the temperature has reached 20 or 30 degrees.

This is definitely not normal.

When Zhao Jiayan and Jiang Yiyi heard this, their expressions changed.

Running for your life again?

"I've slept enough, let's go buy some necessities quickly."

Although Zhao Jiayan was very reluctant, she still quickly picked up her luggage for the sake of her own life.

There was not much luggage that she needed to carry. Apart from her own pistol and bullets, she only had one pound of water and ten pounds of dried meat.

After the two women left the safe house, Yang Yuan walked around the safe house and finally found a button at the door.

He tried pressing the button.

A magical thing happened. The safe house quickly shrank and folded automatically, turning into a box one meter long, one meter wide and only about thirty centimeters thick in the blink of an eye.

There is also a handle on the box for easy carrying.

"Wow!!"

"This is……"

Zhao Jiayan and Jiang Yiyi both looked at this scene in surprise.

When they woke up, why did this safe house become so advanced?

Yang Yuan lifted the box, and suddenly his face became happy, because the box actually only weighed about forty kilograms, that is, about twenty kilograms, which was much lighter than the previous fifty kilograms.

"Don't ask yet, let's go shopping quickly."

He strode towards the safe area.

"Oh, okay. Yiyi, hurry up and follow."

Zhao Jiayan also understood the seriousness of the matter and hurriedly followed Jiang Yiyi.

The two women were not stupid, and they guessed that the changes in the safe house were probably related to Yang Yuan's superpower.

But as long as you know this kind of thing in your heart, there is no need to get to the bottom of it. They are also the beneficiaries anyway.

Soon, they arrived a hundred meters outside the safe zone.
To be continued...
