Lu Yuan immediately understood why the child was crying.
So he handed an oxygen cylinder to Lu's father.
"It's because of the pressure difference between the inside and outside! The oxygen content in the air here is constantly decreasing, causing chest tightness! The child is probably crying because of that!"
Upon hearing Lu Yuan's words, a look of shock appeared on Lu's father's face.
He never imagined things would turn out so badly.
"What? You mean there's no oxygen left in the room?"
"Yes, the outside atmospheric pressure has fallen below the normal threshold. Our room could face an oxygen crisis at any moment. The oxygen concentration is already below normal, so there's a reason why the child is crying. I'll go right now."
At this point, Lu Yuan stopped and handed the two bottles to his father.
“Grandpa and Grandma might not be feeling well either. Take those oxygen cylinders over right now, one for each of you. I’ll figure out a way to solve the oxygen shortage problem later.”
Lu's father nodded immediately and patted Lu Yuan on the shoulder.
"Go quickly. I'll look after Grandpa and Grandma, you go check on the children, they're the most important!"
Lu Yuan immediately turned around and walked over. As soon as he opened the door, he heard Qi Qi crying.
The sound was extremely painful, and Xiaoshan, Lu's mother, and Xiaoshan's mother were all in tears.
Lu Yuan quickly opened an oxygen cylinder and placed it over Qi Qi's mouth and nose.
The moment the button was pressed, Qiqi instantly absorbed pure oxygen. Her face, which had been flushed red, slowly returned to normal, and her crying finally stopped.
The family members breathed a sigh of relief after seeing that the child had stopped crying.
"What exactly happened? Why was everything fine after you let the child inhale a little from this little bottle?"
Lu's mother looked at the small bottle in Lu Yuan's hand with some surprise.
Only then did they realize that what Lu Yuan was holding was actually an emergency oxygen cylinder specifically designed for high-altitude areas.
After Lu Yuan briefly explained the situation to them, everyone realized the seriousness of the matter.
Fortunately, Lu Yuan discovered the problem in time and found an oxygen tank. Otherwise, if Qi Qi had continued to cry and fuss, she might have suffered from oxygen deprivation, in which case even eating the golden fruit would have been of no use.
"So what should we do next? The supplies in the house are insufficient. Can we survive on these oxygen tanks for the time being?"
After taking a breath of oxygen from the cylinder, Xiao Shan immediately felt much better in her chest.
She still looked at Lu Yuan with some concern and asked him a question.
"It's alright, I'll go to the oxygen concentrator right now and see if we can pump oxygen into the house so we can be more comfortable."
However, our house is a bit too big, so we can only install one in each room. We'll have to limit the oxygen supply later, otherwise our electricity supply might not be enough!
After saying that, Lu Yuan left the room and went to the central control room.
The oxygen concentrator hasn't been used yet, so the protective film on it hasn't been removed.
Lu Yuan checked that the oxygen concentrator was in good condition and turned it on.
However, to his surprise, the oxygen concentrator only worked for a few minutes before stopping.
Lu Yuan immediately tensed up. After a while, he finally understood that without air, the oxygen generator could not extract oxygen from it.
Fortunately, Lu Yuan had some spare equipment for electrolyzing water to decompose oxygen.
An electrolysis water device can produce oxygen and hydrogen by electrolyzing pure water. Hydrogen is mainly used for combustion, while oxygen is used for respiration.
Lu Yuan quickly started the electrolysis machine, and instantly the voltage in the entire room began to become unstable.
Even the air conditioner and various appliances stopped working, and Lu Yuan's face immediately showed a trace of worry when he saw this.
"Damn it, I completely forgot that this electrolyte requires a huge current to electrolyze water into oxygen and hydrogen! And what I have here is basically household electricity, which is not enough to provide enough power to decompose a large amount of oxygen!"
Thinking of this, Lu Yuan's heart sank.
Next, there will definitely be a shortage of oxygen, and oxygen is an essential element for the respiration of all living things. Without oxygen, their survival will not be possible.
"Could it be that we really have to open the hole to restore the air pressure in these two places to positive? But if we open the hole, this house will probably be destroyed by the hurricane!"
Lu Yuan now faces two paths.
Alternatively, the whole family could use an electrolysis device to control electricity consumption, but the consequence of doing so would be that other living things would basically not be able to survive.
The other option is to open a passage to allow the air pressure between the residence and the outside world to return to normal. At that time, the external pressure will definitely increase, and the super storm may even directly blow up one's house.
For a moment, Lu Yuan didn't know what to do. He silently returned to his room and watched as his family members, one by one, took oxygen tanks and their complexions finally returned to normal. He felt utterly helpless.
After thinking about it for a long time, Lu Yuan decided to discuss this matter with everyone.
Qiqi has fallen asleep smoothly. In order to ensure that there is enough oxygen in Qiqi's room, Lu Yuan specially got a small oxygen generator and placed it in the room. The room is particularly small, which can ensure that the oxygen is used more fully, thus ensuring a normal supply of oxygen.
However, it is impossible to fill the entire room with oxygen.
After all, only large-scale industrial-grade oxygen production equipment can supply oxygen normally.
It's almost impossible for Lu Yuan to do that; he only has a few small industrial machines.
Therefore, Lu Yuan planned to use these small oxygen generators to help his family transition to a routine.
As for other creatures, such as domestic poultry and livestock, and fish in the river, they can only be left alone for the time being.
Seeing that Lu Yuan's expression was off, Xiao Shan quietly walked over and touched his forehead.
"What's wrong? You don't look well. Did you forget to use your oxygen? Is there not enough oxygen here?"
Hearing Xiaoshan's worry, Lu Yuan sighed and pinched her cheek.
"How could that be? Don't worry, my oxygen supply is more than enough, look!"
As Lu Yuan spoke, he pulled a small oxygen tank out of his pocket.
This oxygen tank can probably last for a whole day.
We have several hundred of these small oxygen cylinders stored at home, which should last them a long time.
