A week after entering the shelter, Chen Xin, who finally waited for the light bulb to stop flickering, quickly opened the iron box, took out the mobile phone, laptop and game console inside, and tore off the tin foil on it three times and two times.

After eagerly opening it, Chen Xin finally felt the happiness brought by technology again.

For modern humans, mobile phones have long been an indispensable thing in life, even without the network and mobile phone signal, a smart phone can still provide many services for human beings.

Although all kinds of fancy and multi-functional and complex APPs are not very eye-catching, if you look closely, you will find that these APPs have already penetrated into all aspects of our lives.

It's like Chen Xin used to take his mobile phone for half an hour every morning before getting up and going to bed, not to brush out something or chat with someone, but to have an obsessive-compulsive habit, always click on every APP installed in the mobile phone.

Even if there is no network signal now, the first thing Chen Xin did after charging and turning on his mobile phone was to subconsciously click on various APPs, wanting to see what new news there was.

However, no signal is no signal, even if Chen Xin swiped all the apps, all the news was a week ago, and the last message was almost all the news of the failure of the interception mission and the meteorite hitting the blue star.

staring at the last news on his phone silently, Chen Xin sighed after a long time, and his mood became a little depressed.

Because this news declares the glorious passing of human civilization yesterday, mankind has entered a new era full of difficulties and obstacles.

It can even be said that this news is the clarion call to end the bright and glorious era of mankind, and now mankind will struggle to survive in the long night of extreme cold.

But after a period of depression, Chen Xin regained his strength.

The old order of human civilization may have been destroyed, but for mankind, it is far from the time when hope has been lost.

The splendor and glory of human civilization may have become a yellow flower of yesterday, but human civilization still exists! Humanity is still alive!

Even though we have lost our homes and fallen into the predicament of lack of food, energy and other materials, the whole world has become a desperate situation under the cover of cold winter and long nights!

But as long as humanity still exists, and we haven't given up hope, we will definitely be able to overcome the difficulties! Overcome all this and rebuild our home!

This is the most precious and greatest spirit of mankind, and it is also the driving force and reason why we have been able to step by step from the fireless era of Rumao drinking blood, become the ruler of this planet, establish a brilliant civilization, and even break free from the shackles of gravity and set foot in a universe that no one has ever set foot in!

Because humanity is always hopeful.

This hope is like a spark, it may be insignificant, it may be insignificant.

But it is precisely because of the existence of hope that we can continue to overcome one suffering after another, overcome one obstacle after another, and pass on the light of human civilization from generation to generation!

It may be true that the predicament we face today is very difficult, but we have much more than our ancestors compared to the ancient times when our ancestors had only sticks and stones and had to face more difficult circumstances!

Fortified and warm shelters replaced ancestral caves

Warm clothes replaced ancestral fur

A variety of fully functional tools replaced the original stone tools

Powerful war machines are far superior to sticks and stone axes

With so many conditions far superior to those of our ancestors, why can't we overcome the thorns and forge a new path with the thorns like our ancestors?

After adjusting his mood, Chen Xin called the computer and sorted out the information on hand.

Because he knew from the beginning that there would be no network and mobile phone signal after hiding in the shelter, Chen Xin filled his mobile phone and laptop with all kinds of information, and even made a mobile hard drive to copy a lot of things into it.

These materials include a full set of text and video explanations of various crops grown in the greenhouse, a complete set of materials on generator fault detection and maintenance, and a full set of tutorials for car maintenance......

In short, everything Chen Xin wanted to get was downloaded and stored in the computer and mobile phone to avoid the difficulty of finding information after there was no network.

And with these information, Chen Xin will at least not know what to do when he encounters problems in the coming days.

Of course, novels, movies, and games are also indispensable.

It's just that there is no Internet, and Chen Xinchang chases several novels that he has no hope of seeing the end in this life, and he can only play the game that has been placed.

But even if it's only a stand-alone game, for Chen Xin, who hasn't touched any electronic products for a whole week, even if it's just cards and minesweepers, it's good, not to mention that there are a lot of 3A masterpieces in his computer.

After touching the electronic products for a long time, Chen Xin did not immediately wait to relax himself in a game, but after checking the storage of various data in the computer and confirming that these important materials were not damaged by the EMP shock wave, he compared his notebook and started the upgrade plan of the shelter on the computer.

Chen Xin had always used a pen to write in a notebook before, and it was inevitable that he would write a little briefly for the convenience of recording, but now that he can use a computer, Chen Xin naturally started to make Excel sheets, so that he can understand the upgrade information of the shelter more clearly and intuitively.

In order to facilitate and intuitively understand the specific situation of the shelter, Chen Xin also made a set of simple drawings of the shelter with CAD drawing, so that he could make better plans.

The easiest and most direct way to upgrade the Vault is to upgrade the Vault as a whole, which is the most convenient and fast, and also the most simple and crude way.

However, the survival points required for the overall upgrade of the shelter are a difficult goal for Chen Xin, whose daily income does not exceed double digits, to achieve in the short term.

"Easy Shelter"

"Upgrade plan 1: upgrade the protection level of the shelter, improve the disaster prevention ability of the shelter, improve the survival comfort, the overall technology of the shelter +1, and upgrade the survival point required 12000"

"Upgrade Plan 2: Expand the living space of the shelter, increase the capacity of the shelter, improve the material support capacity of the shelter, the capacity of the shelter +5, and the survival point required for the upgrade is 15,000"

It is still two different route upgrade schemes, Chen Xin did not look at the required survival point that can raise his blood pressure in the back, he just analyzed how he improved the shelter and improved his living conditions from the two upgrade plans provided by the system.
