Doomsday disaster: Start by building a shelter

After two consecutive trips of transportation.

The large truck transported back all the materials exchanged from the official.

After the routine disinfection procedure, the ten returned construction robots, together with the two remaining construction robots and two engineering robots in the shelter.

All began to gather under the command of Su Wu.

on the 5th underground floor to build a temporary shed for the newly arrived piglets and cattle.

Then.

They began to lay a new soil layer near the sheep house and lawn, and planted saplings and flower seeds.

Then, they also moved some seeds that were not used temporarily.

to the chemical laboratory on the 4th underground floor. These seeds were placed in containers built to imitate the environment in the official seed bank and stored temporarily.

After a busy period.

A piece of land of about 200 square meters was expanded outside the lawn.

On the land.

More than 20 newly planted saplings, transplanted flowers, and shrubs as embellishments gave this place a hint of pastoral atmosphere.

"In the future, the planting area of ​​these trees, flowers and plants will continue to expand."

"It would be better if it could reach more than 2,000 square meters, close to the size of 5 basketball courts, so that it would look a bit better."

"Then, build a fountain in the middle."

"It would be better to use white marble to make statues, pools and floors, and then cover them with a layer of pebbles."

Su Wu carefully drew the plan for the 5th floor.

For now.

There is no material for making fountains in his shelter for the time being.

Even the official warehouse does not have related items.

In the end times, few shelters will hoard these things that are unlikely to be used.

At most, they will be used by their own senior executives when decorating their homes.

But those are all things that are in use and will not be sold.

However, if you really want to find them, you can find them.

There are quite a few buildings decorated with marble in the entire Jianghe City.

Although most of them have become ruins.

But as long as you look for them patiently, you can still find some suitable materials.

After all, Su Wu just wants to build a fountain, and he does not need to build a large-scale building.

As for pebbles, there are even more of them in the wilderness.

Then the water in the fountain and pool.

In the future, it will be mainly provided by the large water tank newly built on the 5th floor.

In fact, in Su Wu's real plan.

Making fountains is a byproduct.

The large water tank, which is expected to reach 6,000 cubic meters, is the real focus.

At present, the water source in Su Wu's shelter almost entirely depends on groundwater and a small water storage room located on the 2nd floor underground.

But now the groundwater is not safe.

Radiation from the surface may penetrate the shallow soil at any time and pollute the underground water source.

If it comes to the worst case.

Maybe the water purification system that has been strengthened by the survival point can no longer purify the sewage. It can only rely on the water stored in the shelter in the past for circulation.

And the 6,000 cubic meter large water tank was built to deal with this worst case.

"The newly built large water tank does not occupy the original space on the 5th floor."

"An additional area will be opened up next to the 5th floor for water storage."

"In this way, more space can be freed up to build a garden."

"We will strive to build the 5th floor into the most beautiful natural world in all shelters in the future."

Su Wu's idea is very beautiful.

However, there are still many things to be solved in order to truly realize it.

For example, earthworms and insects are indispensable in normal forests and gardens.

Su Wu does not want to introduce these things, so he can only build professional farm robots to replace their duties.

And at this time.

Suddenly, the artificial intelligence warning came again on the console screen.

This time it was an earthquake warning.

Artificial intelligence transmits geological exploration data based on the monitoring network. After comparing the historical earthquake data from all over the world in the database.

It is calculated that there is a high probability that Jianghe City will have a very high intensity earthquake next.

As for the specific time.

It is within 2 minutes and 15 seconds.

Su Wu paused for a few seconds on the warning content, and his eyes condensed.

What can be done in two minutes?

Su Wu gave the answer with action.

He quickly shut down and cut off the power supply of all non-essential equipment in the shelter through artificial intelligence.

Including the CNC machine tools and 3D printers in production at the manufacturing center, the engineering team that was continuing to dig and expand the new space on the 5th floor, and the two operating geothermal generators, as well as the lights on each floor, were all forced to shut down.

The robots were in the corner, fixed their bodies. They also entered standby mode.

Then, Su Wu started the reconnaissance drone formation.

Let it take off urgently.

After doing all this.

Seeing that there was still some time, Su Wu logged into his own Internet and satellite network.

He issued an early warning message on it.

With his current status, the warning issued would not be regarded as a joke.

But due to the short time, people who saw the message could do limited things.

At most, they were asked to find a relatively good place nearby.

2 minutes and 15 seconds passed in a flash.

The predicted earthquake came as expected.

First, there was a slight tremor covering all areas of Jianghe City.

Then, a dozen seconds later, a huge crack suddenly appeared in the wilderness without any warning.

At a speed of 1 to 2 kilometers per second, it extended into the distant mountains in the blink of an eye.

At the same time when the crack appeared, it was like a signal.

The intensity of the earthquake in the wilderness began to rise by several orders of magnitude.

The originally flat ground was like a water surface with a boulder thrown into it, and it raised layers of wave-like water ripples.

Then, these vibrations spread to the urban area of ​​Jianghe City in the distance.

In an instant.

The high-rise buildings that had stood firm in the past storms began to swing like a pendulum.

Countless fragments were thrown out from the high floors of these buildings.

Turned into dense showers and splashed on the ground.

A few minutes later.

More cracks appeared randomly in the urban area, the wilderness, and the suburbs.

Large areas of land were broken and sunken.

Some buildings that were unfortunately located in them began to gradually sink down.

And the lower ruins. They simply sank deep underground and disappeared.

Several small and medium-sized shelters were also located in these depressions.

Thousands of people did not even have time to send out any messages for help.

They were pulled deeper into the ground along with their shelters.

Then, under the movement and compression of the huge rock layers, they gradually lost their space.

Until they suffocated to death.
