Global Collapse: Infinite Upgrade Shelters

The next morning, when Su Ze woke up, Xiaoli and Xiaomu had already jumped onto the bed and greeted him in their own unique way.

""Okay, Xiaomu, okay, okay~" Su Ze hugged Xiaomu.

This guy seemed to like the shelter very much. He didn't feel strange at all like last night. He made friends with Xiaoli and got along well with him.

After washing up, the robot had already prepared breakfast.

Su Ze ate breakfast while listening to the housekeeper's report.

After a night of installation, the current elevator has been installed.

The expansion project of the small orchard in the planting area has also been completed.

At the same time, the excavation of the water source area has also been completed.

"Is the water source area completed?"

Su Ze nodded.

The water source area is extremely important to the entire shelter.

Water is the basis of life.

It is no problem to survive for dozens of days without food.

But if you don't drink water within 7 days, you will die.

After dinner

, Su Ze walked in front, and Xiaoli and Xiaomu followed behind.

"There's another elevator."

Looking at the newly installed elevator last night,

Su Ze couldn't help but smile.

The entire elevator is installed in the center of the shelter.

From here, you can go up to the planting area on the top floor.

You can go down to the small nuclear power room on the bottom floor.

On this basis, if the shelter continues to increase in area in the future, you only need to keep digging below and increase the number of floors.

As you approach the elevator, you can smell a smell that only new machines emit.

Su Ze took a deep breath.

Xiaoli and Xiaomu were also very curious about this new thing.

They sniffed in the elevator.

Pressed the third floor.

The elevator ran silently.

A sense of falling came.

Soon.

Whoosh!

The elevator door opened.

The third floor was here.

Su Ze came to the newly excavated water source area on the third floor.

The entire room has been installed with wooden layers on the floor, walls, and ceiling.

"As usual, upgrade first."

Upgrade target confirmed: wooden floor of the shelter water source area.

Upgrade direction confirmed: iron floor of the shelter water source area.

Upgrade points: 1100.

Returned upgrade points: 350 points.

Since the system upgrade, more points are returned after each upgrade, and now it is about 35% each time.

In other words, 1100 points of upgrade points only need 770 points.

A familiar warmth came from my right hand.

The entire shelter water source area has also been upgraded from wooden floor to iron floor.

I feel safe now.

"Housekeeper, simple decoration"

""Yes, Master."

The robot began to simply decorate.

The so-called simple decoration is really simple.

The walls and ceiling are painted white to look neat.

The ground is also simply painted with pressed cement or paint.

This time, the water source area is painted.

After a while , the painting is completed.

Various large water purifiers, small purifiers, sewage treatment devices, and other equipment are brought in.

After debugging, they are connected to the internal network.

"Master, the water purifier and other equipment are all working properly."

"Good, great."

Now, the water source area of the shelter is complete.

"Well, it looks like there is still a lot of room. Let's dig out the sewage and waste treatment facilities nearby and start working on them right away."

""Yes, Master."

The sewage and waste treatment center is also one of the necessary areas of the shelter.

In this way, sewage and waste can be reused.

For example, after sewage treatment, it can be used to provide water for plants in the planting area.

Leftovers can also be fermented and used as fertilizer for plants.

Washing water and bath water can also be treated.

These are mainly for a healthy small cycle inside the shelter.

"Okay, now let's go to the orchard in the planting area."

I took the elevator again and arrived at the highest planting area of the shelter.

"Hmm? The growth rate is really fast, it's only been less than three days."

The various vegetables in the planting area in front of him have already sprouted and grown to a height of about one palm.

The growth rate of the upgraded seeds is really amazing.

At this rate, a batch of seeds can be grown within seven days.

A batch every 7 days, which means about 4 harvests a month.

This growth rate is like riding a rocket.

Su Ze alone, plus Xiaoli and Xiaomu, can't finish eating the vegetables every day.

In addition to vegetables, the growth of wheat and rice not far away has also been accelerated.

It looks like it will be harvested in a few days.

"This upgrade is so cool."

As long as the temperature is suitable in the shelter, there is basically no spring or winter, and things can grow all year round.

By then, there will be so much food that the warehouse will burst. It will be harvested in a few days, and then it can be traded in the supermarket.

These vegetables, wheat and rice made Su Ze understand the benefits of seed upgrades.

"Then let's upgrade the fruit trees and achieve fruit freedom."

Su Ze came to the orchard.

As the wooden planks had been used up, there was no plank layer yet.

Su Ze looked at the fruit trees one by one.

"Upgrade these first."

"Upgrade target confirmed: Peach Tree"

"Upgrade direction: Increase growth rate.

Upgrade points: 130 points

"Upgrade target confirmed: Apple Tree"

"Upgrade direction: Increase growth rate.

Upgrade points: 125 points

"Upgrade target confirmed: Pear Tree"

"Upgrade direction: Increase growth rate.

Upgrade points: 135 points
