Doomsday disaster: Start by building a shelter

The laser, which was condensed with extremely high temperature, slowly cut open the twisted metal shell in the tower top chassis.

The wires and circuit boards inside that had been shaken into a mess were exposed.

Su Wu felt a little dizzy after just one look. He had no idea whether they were in good or bad condition.

But it didn't matter.

He waited patiently for half a second.

Lines of inspection reports began to appear on the screen.

Su Wu moved his eyes and scanned them. He immediately knew what was going on.

The situation was not serious.

Only a small amount of raw materials needed to be added, and the engineering robot could repair it completely.

Without hesitation, Su Wu immediately asked the engineering robot to start repairing.

The same survival points were used to upgrade items.

The two states of damaged and intact will bring different upgrade routes.

The former is equivalent to repairing on the original basis, and strengthening is just a by-product. The latter is a special upgrade to give the item the highest possible technological content.

Therefore, whenever possible, the best choice is always to repair the item first and then upgrade it.

Two hours passed in a flash.

With the combined efforts of several construction robots and transport vehicles, the repaired signal tower was dragged into the exit passage of the shelter.

Then, all external actions of the shelter were suspended.

The outermost gate of the exit passage began to slowly close, completely isolating the high temperature outside.

Then at the end of the passage, the explosion-proof door near the lifting platform opened automatically. The cold wind from the central air-conditioning of the shelter slowly entered. Gradually dissipated the residual heat in the passage.

Su Wu left the control center and came to the lifting platform.

He looked at the communication tower that almost occupied the front and back of the exit passage and stood there for a moment.

Finally, there was an action.

"Be willful."

Upgrading the signal tower requires survival points, and in the original plan, survival points are to be supplied to the control center first for the manufacture of CNC machine tools and 3D printers.

Su Wu's operation this time will undoubtedly delay the original plan.

But he is willing to do so.

Reach out and press the top of the signal tower.

The stinging heat transmitted from the palm skin made Su Wu subconsciously shrink his hand.

[Communication Signal Tower]

[Evaluation: This is a communication base station with complete signal sending and receiving functions. ]

[Upgradeable sub-options: expand capacity, expand range, increase penetration. ]

No excessive introduction.

For the signal tower, only three simple and clear upgrade options pop up on the system panel. Expand the number of people who can use it at the same time, expand the signal sending and receiving range, and increase the signal penetration ability.

Each option is very useful.

But the limited survival points determine that only one of them can be selected for the time being.

Su Wu carefully considered it and chose to upgrade to increase penetration.

If the capacity is not enough, the network will be a little stuck at most. If the range is smaller, the number of shelters that can be covered by the signal will be a little less. There is no essential difference.

But penetration is different.

This is a black technology.

It can ignore obstacles and easily penetrate soil and rock formations. Transmit the signal directly to the inside of the shelter deep underground.

In this way, even if the owner of the shelter is unwilling to cooperate in opening network permissions, the members living inside the shelter can still receive Su Wu's network signal.

However, the penetration attribute can only solve the problem of sending signals.

If there is no communication device installed on the surface of the shelter itself, even if the penetration attribute is loaded, the signal tower will still not be able to receive information fed back from the shelter members.

This is equivalent to changing from the Internet that can communicate to a TV that can only watch one channel.

But this actually has little impact.

As long as the unilateral information monopoly is broken and the shelter’s authority agrees to open the network, it will be much easier.

At most, the shelter members who use the network will pay some equipment rental fees themselves and pass the benefits to the shelter owner.

After the upgrade option was determined, the ten survival points disappeared instantly.

A burst of white light spread on the signal tower, quietly smoothing its deformed appearance due to violent tearing one by one, making it as new as ever.

Then the top of the tower was integrated into a closed body that was similar to a sphere.

It looks quite simple and beautiful.

Su Wu reached out and touched the sphere. The cool texture from his fingertips indicated that it was a metal with an unusually smooth surface.

Perhaps it was iron, or perhaps some special alloy.

"Go and try it."

Expectation appeared in Su Wu's eyes, and he was a little impatient to test the function of this new signal tower.

He issued several related commands through the tablet computer he carried with him, and then turned back to the control room.

Behind him, the explosion-proof door of the lifting platform began to close slowly. The signal tower and several robots standing near the signal tower were isolated outside the shelter.

Ten minutes later.

A brand new 15-meter-high signal tower.

Was erected on the top floor of a small bunker on the surface.

[Wireless charging starts matching. ]

[Matching successful. ]

[The communication signal tower has been included in the regular power supply sequence. ]

[Communication signal tower starts starting. ]

[Startup successful. ]

[Wireless network has been deployed. ]

The second underground floor of the shelter.

Control center.

Su Wu unlocked the screen of his mobile phone and searched for a network icon with full signal.

He clicked the link.

A moment later, a simple search page popped up on the screen of the mobile phone.

That was a special prompt that would only pop up when connecting to the network for the first time.

"Success."

Su Wu knew that from this moment on, the communication signal tower had completely taken over the original local area network. And its coverage range was expanded from the inside of the shelter to all places within a radius of 15 kilometers around.

Within this range.

Anyone with a wireless communication device can connect to or receive his network signal.

The bud of a new Internet was born here at this moment.

13 kilometers away from Su Wu's shelter.

A private shelter also located in the suburbs.

A young man who had just charged his mobile phone with a hand-cranked generator was boredly flipping through the various settings in his mobile phone.

In the days since entering the underground shelter, he had already watched all the novels, movies and videos stored in his mobile phone.

Now, he didn't know what to do with his mobile phone.

"I should have been more diligent and downloaded some stand-alone games that can be played offline."

Wang Hao felt very regretful.

It's not like he had never downloaded games before, but who would have known that those games that were clearly marked as stand-alone games could no longer be played after disconnecting from the Internet.

Isn't this a scam?
