However, even if the ventilation duct is upgraded, the air in the shelter is still filled with smoke and various harmful gases. So after Chen Xin completed the upgrade of the ventilation duct, he hurriedly wanted to turn on the forced ventilation function added after the upgrade to ventilate the air in the shelter.

But he found the switch for forced ventilation, and pressed it twice but had no reaction.

Chen Xin was stunned for a moment, and quickly checked around, and then he realized that the forced ventilation function required power.

Fortunately, the ventilation system line that was upgraded to the system has been directly connected to the distribution room, and Chen Xin needs to connect or plug it. He only needs to turn on the line control switch from the distribution room to start forced ventilation.

After struggling for a long time, Chen Xin finally heard the sound of the fan running and the wind caused by the high-speed flow of air. He then felt relieved.

However, the battery's power is limited after all. Chen Xin was worried that the power was insufficient and he filled the generator with oil. After starting the generator to ensure power supply, he collapsed on the sofa in the living room.

After more than half an hour of forced ventilation, Chen Xin felt that it was almost done. He took off the gas mask on his face and smelled it. He felt that he could no longer smell the smoke, so he went to turn off the forced ventilation.

Although the forced ventilation function saved Chen Xin's life this time, this function does not need to be turned on all the time. Moreover, it is not only noisy but also very power-consuming when turned on.

If it is not necessary, it is better to turn it off to save resources.

After closing the forced ventilation, Chen Xin returned to the sofa in the living room. Only then did he put down the worries and panic caused by what happened just now, and his mind began to work on to think about the problem.

This incident sounded the alarm for Chen Xin. His seemingly safe shelter actually had loopholes. If he hadn't had a system to upgrade the ventilation system this time, he might have been suffocated to death.

Even if he didn't wake up in time, he would probably be suffocated to death in his sleep.

So if Chen Xin wants to survive well, he must improve his vigilance, and at the same time, he must make good use of the system and upgrade the shelter as much as possible so that the shelter can better protect him and provide him with survival guarantees.

This time, the matter also strengthened that if Chen Xin was not necessary, all the survival points would be invested in upgrading the shelter rather than upgrading other disposable items, and they would always reserve a survival point for emergencies.

It’s like this time, if Chen Xinshu didn’t have enough survival points on his side, even if the system could upgrade the ventilation system, he wouldn’t have enough survival points to do this. In the end, he might still be suffocated because the harmful gases in the air exceeded the standard and the oxygen content was insufficient.

Now Chen Xin can get 10 survival points every day. The reason why he can save enough 100 survival points that can be used to upgrade the ventilation system in two days is because he achieved an achievement when the system settled the survival points for the first time.

“Own a refuge, rewarding 100 points of survival”

Through this achievement, Chen Xin also understood that this system also has a way to obtain survival points through achievements.

However, Chen Xin is still confused about what things can achieve, and he has not conducted in-depth research, so he currently mainly relies on the settlement of 10 points every day to accumulate survival points.

Of course, with the upgrading of the shelter, Chen Xin's living conditions are getting better and better, and there will be more and more survival points that can be settled every day.

Therefore, Chen Xin is still confident in his future. Even if the world falls into the doomsday, as long as he works hard to survive, he will definitely live better and better with systematic help.

With such belief, Chen Xin cheered up again.

Although he was choked by the smell of smoke and harmful gases before, when the oxygen cylinder provided oxygen, the impact of the harmful gas on his body was gradually fading, and his mind became much clearer.

Chen Xin, who has recovered, thought seriously that the condition for system to increase the daily settlement survival points is to improve his own living conditions. So what are the things in the shelter that can improve his own living conditions?

Chen Xin took out his laptop, which recorded some things that Chen Xin summarized two days ago.

He looked through the records above and looked at the contents listed above. After thinking about it, he took out the pen clipped on his laptop, turned to a clean page, and re-listed a new table on it. The first item he wrote was medical care.

This incident reminded Chen Xin that the first priority of survival is to ensure his own survival. Such a perfect medical facility can undoubtedly greatly improve his chance of survival.

Not to mention anything else, in the current environment of lack of medical treatment, Chen Xin could not leave the shelter to see a doctor even if he had any disease. He only had some common medicines. It would be okay to have a cold or fever. If it was an unusual disease, he could really wait to die with his eyes closed or just give himself a knife.

Therefore, a complete medical facility is a must-have for Chen Xin. It is best to have a special medical room or simply a medical cabin in science fiction works that can be cured even if the head blows away.

Fortunately, with the existence of the system, Chen Xin believes that this is not difficult to accomplish, and all he needs is a survival point.

But after thinking about it carefully, Chen Xin added food to the medical field.

Eating is the first urgent need that everyone will encounter every day. No one dares to say that they don’t need to eat.

This is the same for Chen Xin, who also needs to eat.

Although he stored enough food in the shelter, he would eat it all, so he opened a planting greenhouse, and sorted it out two days ago and sowed the first batch of seeds.

Maybe it's time to upgrade the greenhouse next?

Chen Xin listed this article as a priority option for the next upgrade, but did not serve as the first option for upgrading his refuge.

Because before upgrading the planting greenhouse, Chen Xin must consider how to maintain the greenhouse operation.

You should know that Chen Xin’s greenhouse uses fill light to provide simulated light to crops, but these fill lights are all power-consuming customers. If you want to upgrade the greenhouse, he must first consider upgrading the power system to ensure the power required for the greenhouse to operate.

However, when thinking of the greenhouse, Chen Xin decided to go to the greenhouse to see it. He didn't know if the seeds he had sown had sprouted.

Chen Xin was very concerned about this. After all, it was related to whether he could eat fresh vegetables and whether he could still have something to eat after eating the reserved food.
