Global Cataclysm: Infinitely Upgrade Shelter

"Stride, stomp—".

The sound of crisp footsteps sounded in the dark bomb shelter.

After passing through a gentle ramp up to 100 meters, Zhao Chen arrived at the underground space 20 meters underground.

According to the information of the provisional title deed.

This bomb shelter is 50 meters long, 40 meters wide, and 4 meters high, with a total volume of 8,000 cubic meters.

If you survive alone, you can definitely live a very nourishing life.

【........】

In an empty bomb shelter.

There are only four places where all aspects of the upgrade can be carried out.

However, there are many items that can be upgraded in the items that Zhao Chen carries, and the prices are very affordable.

"There are still two months to go before the global catastrophe. "

"The increase in the defense level of the refuge is not in a hurry for the time being, and it can be postponed for the time being. "

"The sewage system and ventilation system are not in a hurry, and now the outside world can still survive and can be used. "

"However, the power system is about to be restored quickly. "

“........"

Hold a flashlight in one hand and touch your chin in the other.

Zhao Chen kept thinking about the use plan of survival points, although the newbie gift package rewarded 1000 survival points, but good steel should be used on the blade, if you use it casually, it will definitely reduce the possibility of survival.

Nothing else will be mentioned for the time being.

Restoring the power system is an absolute priority.

After all, this rock shelter was pitch black, and if it weren't for the flashlight in his hand and rhubarb beside him, Zhao Chen really wouldn't dare to walk in alone.

Humans are basically afraid of the dark.

In this pitch-black environment twenty meters underground, if you don't have light and creatures to accompany you, you will go crazy sooner or later.

"Upgrading the abandoned power system. "

“......."

Zhao Chen said silently in his heart.

The next second.

The 1000 survival points in the system panel instantly dropped to 200 survival points.

Then, the abandoned power system of the rock shelter began to slowly recover, and the ten remaining light bulbs suddenly lit up, giving the dark space a faint glow.

Although it is not illuminated, you can still see the environment of the entire rock shelter at first.

Glance.

There is nothing.

The entire rock shelter was empty.

[Inferior power system].

[Upgrade direction: primary power system (2000)].

[Upgrade effect: 300 kWh of fixed power supply per day, can be provided to any building in the shelter].

[Attributes can be attached, and a certain survival point can be consumed according to the effect].

【........】

To upgrade the power system again, you need a full 2000 survival points.

This is not the number that the barren Zhao Chen can make up for a while, and he can only give up for the time being.

Inferior power system.

Fixed power supply of 30 kWh per day.

Wind power, water power, and diesel fuel are not used.

Although I don't understand the principle of electricity generation, as long as there is electricity, 30 kilowatt-hours a day in the early stage is barely enough.

After all, ten light bulbs consume 0.1 kWh of electricity per hour

"It's just a pity that the backpack is too small to fit too many things. "

"Otherwise, bringing a quilt and a tent will improve the quality of sleep to a higher level. "

"It's really cold in December. "

“......."

Zhao Chen rubbed his hands and raised his body temperature a little.

Although wearing a down jacket, this rock shelter is located in the suburbs, and the entrance is not doored, and the cold wind of winter is constantly howling in, which is still in the afternoon, and it will be even more difficult in the evening.

When the interior of the shelter is installed, I will have to build a sturdy gate.

On the one hand, it is to insulate from the cold.

On the other hand, it is also to guard against humans.

In the case of a global catastrophe, Zhao Chen did not want to put himself in a dangerous situation.

"No, I'm going to chop some firewood and come back. "

"Otherwise, even if you don't freeze to death tonight, you'll catch a cold. "

"Rhubarb come with me. "

“......."

I put my phone in my pocket.

Zhao Chen took out the light iron axe in his backpack and took off the cotton cloth wrapped around the blade of the axe.

It can not only chop wood, but also defend itself.

It's definitely good stuff.

As for the backpack with compressed biscuits, canned meat, and mineral water, Zhao Chen planned to put it in the rock shelter, anyway, he was cutting firewood nearby, and with the vigilance of rhubarb, no one else could steal it.
