Because this safe house is moisture-proof, the floor has three floors, and he doesn't understand the principle, but it must not be too bad, and it is better than sleeping on the ground.

It only took half an hour for the safe house to be installed.

The overall height of this safe house is only two meters, and the length and width are three meters, which is nine square meters.

Half a meter above the floor are three small beds, all of which are vertical, that is, with their heads facing inward and their feet facing outward, and the beds are only one meter wide and two meters long.

There are partitions between the three small beds to prevent privacy from leaking, but there is no door in the 'room'.

There is only one door in the whole portable safe house, that is, the entrance, and in the middle is a movable door that opens inwards alone, which can be closed with a mosaic latch from the inside and cannot be opened from the outside.

The three cots have a cat's eye on the headwall of the bed to see the outside.

The cots on both sides also have cat's eyes to see the outside.

The same goes for the door, which has a cat's eye that allows you to see outside.

There are also small vents at the top of the walls, which are cleverly designed to ensure ventilation without water entering on rainy days.

Between the three small beds and the door, there is a corridor three meters long and one meter wide, and there is also an eaves of the same size above the corridor.

From the outside, it looks like a cube two meters high and three meters long and wide.

"How does it look like a public toilet?" When Yang Yuan saw this shape, he couldn't help but feel a little disgusted.

In the past, the public toilets on the roadside in the city looked like this, and they were the kind of iron-covered public toilets that did not distinguish between men and women.

"It's bigger than a public toilet, but it's beautiful."

Zhao Jiayan covered her mouth and smiled, a look of nostalgia flashed in her beautiful eyes.

She hadn't slept in the house for more than three years, and she was sleeping in the open air, although this portable safe house was very simple, but she liked it very much, but the safety needed to be strengthened, and she might not be able to sleep in it.

Jiang Yiyi looked at this 'small house' with big eyes without blinking, with some joy in her eyes, she liked this kind of small house very much, just like playing at home.

"If you buy everything, let's live in it first, it's better than not living at all. Much better than those who stay up all night around a campfire anyway. ”

Yang Yuan looked at the upgrade data, that's right, this safe house also has data:

[(Pseudo) portable safe house LV.1: 0/5 (a portable house made of stacked bricks, it's okay to use it for shelter from the wind and rain, but don't mention safety to me)]

“…… Very good. ”

Yang Yuan grinned.

If you can upgrade, then no problem.

As for security?

Later upgrades, there will be.

But how do you gain experience in this safe house?

You can get it by living in it, right? But how long does it take to experience a little?

You'll have to try it first, and hopefully it won't be too long.

"Alright, go to sleep, I'll keep vigil tonight."

Yang Yuan saw that Zhao Jiayan had finished the barbecue, walked over and took a piece to eat, and said, "If you are hungry, eat the barbecue first, and if you are not hungry, go to bed quickly." ”

"I was just full. What about Yiyi? Zhao Jiayan asked.

"Yiyi is also full."

"Then go to sleep, you have a good rest tonight, you didn't sleep well last night."

Yang Yuan took out his pistol and said, "If I can't hold it, I will call you." By the way, let Yiyi sleep in the middle. ”

"Okay."

The two girls went to sleep.

Yang Yuan closed the door, added a few pieces of wood to the campfire, and then sat on the ground with his back to the door of the safe house to pass the time.

Every once in a while, of course, he would get up and patrol and walk around the safe house to keep anything from approaching.

An hour passed in the blink of an eye, and the safe house experience increased by two points.

"Two more experience in an hour?"

Yang Yuan's eyes flashed: "It should be a person who adds a little experience to an hour, right?" In this way, the experience of house type items is also calculated by hours. ”

He resisted the thought of going in and sleeping himself, and waited patiently.

"The power armor has about two hours left, and it can be upgraded again."

At this time, it was already more than twelve o'clock in the middle of the night, and last night because there were bonfires everywhere, I didn't feel anything, but tonight there was only one bonfire here, and the other bonfires were two or three hundred meters away, so it was a bit cold.

"There will be monsters at night in this world, but monsters are rare, I shouldn't be so unlucky, right?"

Yang Yuan was a little stunned in his heart, and carefully checked the pistol.

"I should have bought some bullets before, but now it's not convenient to brush the experience of the pistol, the sound is too loud, and it is easy to attract monsters."

Minutes and seconds passed.

Soon it was close to two hours, and the experience of the safe house was not yet full, but the experience of the power armor was full first.

[(Pseudo) Power Armor LV.2: 200/200 (Upgradeable)]

Yang Yuan immediately stood up, put the mask down, and chose to upgrade.

In an instant, the experience was reset to zero, a white light invisible to outsiders flashed, and the entire power armor was optimized from the inside out, both the material itself and the various systems.

This time it took a little longer than before, but it only took two or three seconds to optimize.

"I don't seem to feel depressed anymore."

Yang Yuan was secretly happy in his heart, he found that after this upgrade, even if the mask was still put down, he would not feel depressed.

In addition, it seems that he has an additional external 'vision'.

This field of view is like a radar, which can 'see' the model of the environment within 100 meters, except that it cannot see the colors, and there are no other drawbacks.

Moreover, this radar system can also scan the sky and the underground, but the underground can only scan a depth of about two meters for the time being.

These 'visions' will appear in the mind, but it is not like your own mind, but the calculator that comes with the power armor, which is an external brain, after binding neurons, especially after two consecutive upgrades, this external brain is already somewhat useful.

"Is there a built-in radar system for power armor?"

Yang Yuan was overjoyed in his heart, and tested other functions, and found that the beam of light particles ejected from his hands and feet was more powerful, and the driving force was at least ten kilograms or more.

Although this little push force is still small, it is many times better than when it was first manufactured, when it was almost invisible.

Just upgrade a few more times and you might be able to fly.

And the power, which has also been enhanced a lot, can speed up movement, and has initially possessed the power effect of 'power armor'.

Finally, the most important defense is the original plastic shell, which is more textured, and should now be able to defend against pistol bullets.

[(Pseudo) Power Armor LV.3: 0/400 (You can already wear it to pretend to be forced, but it's best not to wear it to fight.] ）】

Yang Yuan smiled with satisfaction: "The next upgrade, it will take seven hours, and you will be able to upgrade again tomorrow morning, and you should be able to fight in clothes by then." ”

Suddenly, in the radar field of view of the power armor, a small whirlwind appeared a hundred meters away, rolling up dead leaves and spinning in the air.

He jerked in that direction, raising his pistol to aim.

However, in the radar field, the small whirlwind seemed to sense the threat, and slowly disappeared away with the swirling dead leaves, disappearing out of the radar field.

"What's that?"

Yang Yuan frowned slightly, stared in that direction for a long time, and there was no movement.

"A monster of the night? Or is it just a small tornado? ”

He did not let his guard down, and was secretly on guard.

In this process, I don't know if it's an illusion, he always feels hotter and hotter, and the temperature is getting higher and higher.

"Is it too much fire?"

He stepped back a bit, away from the campfire.

But the heat is not decreasing, and there is even a tendency to get hotter and hotter.

"This feeling ......"

Suddenly, he seemed to think of something, and his face changed slightly: "The drought is coming?" ”

He hurriedly looked in the direction of the security zone, but saw that the security zone was still quiet, and there was no other movement from the military.
