"Cough cough cough!" Chen Xin woke up due to choking.
Today is already Chen Xin's third day in the shelter. After two days of adaptation and adjustment, Chen Xin feels that he has adapted to life in the shelter.
But today, for some unknown reason, the entire shelter was filled with the choking smell of cigarette smoke, which woke Chen Xin up from his sleep.
Coughing and covering his mouth and nose, Chen Xin got up from his bed and turned on the light in the room.
He shook his head and put on his clothes, but he still felt dizzy and even his breathing was not smooth.
Chen Xin knew that this was not because he had not yet woken up, but because there were harmful gases in the choking smell of smoke in the air. He had inhaled a lot of smoke in his sleep, which affected his breathing.
If he hadn't been woken up by choking and continued sleeping like this, he would most likely have died from lack of oxygen or harmful gas poisoning in his sleep.
After reacting, Chen Xin quickly found a gas mask and an oxygen bottle from the cabinet nearby. After taking a few breaths of oxygen, he put on the gas mask.
After taking a few breaths of oxygen, Chen Xin finally recovered. Only then did he have the energy to think about what happened.
There should be no fire in the shelter because he never used any open flames. He even used an induction cooker to boil water in the past two days.
But at this moment, Chen Xin didn't think much. He ran to the garage and picked up the small fire extinguisher placed in the trunk of the car. Then he checked various places in the shelter.
However, what surprised Chen Xin was that there was no fire in the shelter, nor was there any smoke.
Where does the choking smell of smoke in the air come from? These choking gases were obviously the smell of something burning. Chen Xin would never believe it if nothing burned.
But when Chen Xin started checking again, he finally discovered that the smoke came in from the ventilation vent of the shelter, and that the smoke entered the shelter from outside.
This discovery made Chen Xin react. There was a fire outside!
In two days, did the fire caused by the meteorite impact finally burn here
But this discovery made Chen Xin feel extremely helpless, because even if he knew the cause, he could not solve the problem.
That was a fire that spread to the entire world, and most of the vegetation would be ignited. Although Chen Xin did not go out, he believed that the mountain where his shelter was located should have burned, otherwise he would not be allowed to go out. The shelter has such a strong smell of smoke.
You must know that the ventilation system of the shelter is specially designed. Under normal circumstances, smoke and toxic and harmful gases will be filtered.
But the current situation... It is obvious that the smoke concentration outside has exceeded the filtering and endurance limits of the ventilation system.
Chen Xin felt helpless and desperate. Was he going to die from the smoke
Although he prepared gas masks and oxygen bottles, there is a limit to how long these items can be used.
In this environment where the smoke is getting thicker, even if the quality of the gas mask bought by Chen Xin is good enough, it can only last for a few hours at most, and the filter element on it must be replaced to ensure the filtration effect, and the oxygen bottle can only be used Two hours.
Although according to Chen Xin's estimation, the wildfire outside will not last long and will be extinguished due to the drop in temperature caused by the sky being obscured by dust clouds, this time will still last for several days or even more than a week.
Chen Xin originally thought that his shelter's ventilation system was enough to ensure his survival for such a long time, but now reality gave him a merciless slap.
The ventilation system that was previously thought to be able to withstand the fire clearly failed to withstand the invasion of wildfires. If Chen Xin could not come up with a solution, after the gas mask and oxygen cylinder failed, he would probably be like those who were smoked to death in the fire scene. Like people, they were smoked to death in this shelter.
Escape? This is obviously impossible.
The smoke has reached the inside of the shelter. It is conceivable that the outside is surrounded by wildfires. Even if Chen Xin opens the door of the shelter and runs out, it will only change from bacon to roast duck in the oven.
And even if he could run out, where could he run to
This fire is not burning his mountaintop, but super fires all over the world.
At this moment, more than 90% of the vegetation on the entire Blue Star has been ignited by the heat released by the meteorite impact. Flames are burning everywhere on the Blue Star's surface, and there is no place to escape.
There may be no flames on the sea, but how can Chen Xin run from the inland to the coast
Now all transportation systems have been shut down due to the impact of meteorites. The country may still have secret routes, but how can such things be open to ordinary people like Chen Xin
And now that he can use this kind of secret line, Chen Xin can just run a hammer and stay in the country's secret bunker.
As for official shelters, that is indeed an option.
But there is a core question here, that is, how should Chen Xin get the closed official shelter to open for him in such a situation of fire all over the sky.
You must know that even the door of Chen Xin's own shelter is a 12-centimeter-thick solid metal explosion-proof door. Let alone knocking it with your hands, even if you hit it with a hammer on the outside, you may not be able to hear it inside. What's more, for safety reasons, Chen Xin Two new doors were also installed.
One can imagine what the gate of the official shelter must look like.
So Chen Xin never considered the option of escaping from the beginning.
If he doesn't run away, what should he do to survive
The ventilation system has now reached its limit. Unless I replace it with a new, stronger ventilation system, I will end up being suffocated to death in this shelter I built with my own hands!
etc! Chen Xin suddenly became excited and thought of an important point that he had overlooked.
He really could use a stronger ventilation system because he has one!
Thinking of the system, Chen Xin quickly called out the system interface, and then aimed his gaze at the ventilation duct of his shelter.
Sure enough, the ventilation ducts in sight lit up, and an upgrade plan was given.
"Natural ventilation ventilation system"
"Upgrade plan one: upgrade the filter material, improve the air filtration level, add forced mechanical ventilation function, and upgrade the required survival points to 100"
"Upgrade plan two: upgrade the pipe material, improve the insulation level, add temperature adjustment function, and upgrade the required survival points to 100"
Without thinking, Chen Xin directly chose the first upgrade plan.
With his confirmation, the same grid-like light as when the system was first started appeared again in the implementation, but this time the light only covered the ventilation ducts.
Soon, the glory dissipated, and the ventilation ducts of Chen Xin Shelter had been completely renovated, and the upgrade was completed. (End of chapter)
