【Integrity】: 100%

[Facilities]: nether energy water well, large vegetable culture medium, ventilation and lighting windows, three-stage tunnel defense...

[Extraordinary ability]: The water of a mermaid, the wind of a lion

[Currently Available Permissions]: Refactoring, China Unicom

"Sure enough, the game recognizes this upgrade method. Now the area has become 320 square meters, and my number of floors has also become the second floor."

"Then next..."

Discharge 12 damaged safe house cores one by one, and open the area upgrade function of the game panel.

After putting everything into the game panel, as Su Mo's voice fell, all the cores began to dissolve.

This time, compared to the brutal collision before, the impatient violence expanded.

The newly-appeared layer is much more soothing, and it goes in gently, and then gently shakes.

At the end of the line of sight, the wall began to slowly move back.

This progress has always maintained a very stable turtle speed, and as the wall moved back, the area began to become larger.

After standing and watching for a while, and realizing that it would take a lot of time to expand the area, Su Mo simply walked out of the small door.

"The previous living floor will become the second floor, and the new one will become the first floor. After being sacrificed to the deep-sea refuge, it will become the garage of the base. It seems that the gate must also undergo some renovations!"

The current three-way corridor leads directly to the second floor of the underground refuge, and the first floor has a small door in the corridor, which is very inconvenient.

According to the design of the deep-sea shelter, the underground shelter will also connect the three floors through stairs in the future.

So there is no need to design the entrance door in this way.

As long as the garage door is upgraded, defensive passages are set up through the stairs in the garage, extending down section by section, which is safe and convenient.

Close the gate of the corridor, and watch the small mountain bag still squirming slowly due to the expansion below.

Picking up the Oreo beside him, Sumo walked in the direction of the deep sea shelter.

Chapter 138 Sacrifice, the magical power of floating (third)

It looks close, but it looks far away. This is Sumo's thought when he was going to the deep sea refuge.

From afar, seeing the hills in the underground shelter getting smaller and smaller, suppressing his unsteadiness in his heart, Su Mo simply quickened his pace again and turned to a trot.

"After the sacrifice of the Deep Sea Refuge this time, it is completely useless, including the gate on the first floor, which also needs to be opened inside to open the winch, which is a bit wasteful!"

Thinking of this, Su Mo was a little embarrassed.

Although it is true that there is no problem in concentrating all the things and resources in one shelter, it would be very wasteful to just abandon this level five shelter.

A large number of people are still living in the worst wooden houses, with air leakage everywhere, but they themselves use the large reinforced concrete flat floors to sit idle.

Shameful waste!

"It is impossible to be idle, you must find a way to use all the resources"

While trotting, Su Mo pondered in his mind.

After walking this section of the road so many times, there are still marks of land tiger wheels on the ground, and with Oreo leading the way, Somo began to study how to recycle waste.

The most lacking things in the last days must be food and drinking water.

As for the issue of food, we can continue to study and grow indoors in the base.

In the early days when there was only Su Mo alone, it didn't take too much thought. The food from the treasure chests, even if they were opened, would be enough for half a year.

"There is no electricity in the deep-sea shelter. Even if I want to grow indoors, I can't do it without fluorescent lamps to supplement the light. Therefore, the item of growing food must be passed."

After silently crossing this item out in his mind, Sumo began to study the possibility of storing drinking water again.

At present, the daily seven liters of nether energy water in the base is fully enough for a day's drinking needs, and only 500 survival points are needed to continue to expand the output.

But there are too many secrets about phantom energy water. Before researching to find out what is special about it, Su Mo still made up his mind not to sell it if he could.

In the trading market, now that Xueshui is available, the market price of Youneng Water is also developing in a two-level trend.

In the hands of some "rich" people who have successfully hunted aliens and have a lot of good things in their hands, the price of psionic water is not expensive.

In contrast, Nether Energy Water can instantly heal injuries. When medicines are in short supply in the early stage, a few sips of Nether Energy Water may be able to hang one's life at a critical moment.

It is precisely because of this that these people flock to it and keep raising the price of nether energy water.

But in the sinking market, that is, for the "poor" who are still on the food and clothing line, the price of psionic water is not within their acceptable range.

Besides, not only can they not afford phantom energy water, but they are also unwilling to buy it.

Ordinary water resources have become worthless as the snow falls.

There are flakes of snowflakes everywhere, as long as you spend a little effort to collect them and boil them to precipitate impurities, they can be stored in large quantities.

At least until the next water crisis comes, water will no longer be a "trading currency".

"correct!"

"I can think of a way to renovate the deep-sea refuge. With the blessing of the mermaid, the dirty things from the outside world can't get in."

"In the early stage, it can be used as a backup reservoir, and some clean snow can be stored in it. After it thaws into a clean water source, it can be enriched with ordinary water!"

"And you can also find a way to build a large water tank in the underground shelter, take this opportunity to get more water, build a purifier, connect the water line, it means that the base has tap water!"

After patting his head, Su Mo stopped, took out the page that recorded the design drawing of the shelter, found the blank space on the top, and neatly wrote down the word "reservoir".

The human body needs water for basic needs and for everyday life.

Later, taking advantage of the development period between each disaster, a large amount of vegetables and food with a short growth time are cultivated on the ground, which also requires a large amount of drinking water reserves for irrigation.

Whether it is from the present or the future, having a huge reservoir is always beneficial and harmless.

As for the extra consumption and the need for shelter cores, Su Mo laughed after looking at the remaining 8 complete safe house cores still lying in the storage space.

Originally, what was most lacking was a complete core to expand other modules, but unexpectedly, what was most lacking now became a damaged core.

"So, the underground shelter needs to build two separate modules, one is used to store water, and the other is used as a food cold storage."
