He's been trained to control oxygen, and that uncomfortable feeling, he knows.

Although it was before returning to China, he still remembers that experience vividly.

That kind of oxygen control training can improve physical fitness, but it is carried out under the control of a professional team, and there is no danger.

And she is facing this, there is no guarantee in any situation, how uncontrollable it will be, he dare not imagine.

What's more, the environment in the underground storage room, she is such a person who is afraid of the dark.

Since he was a child, where did he let her suffer even a little pain, and the separation at the airport at the beginning made him heartbreaking.

Now, if it were now, no, he couldn't think.

His thoughts raced, and he had already run to the door of the underground storage room.

The door, which had no combination lock, was an ordinary iron lock.

The lock cylinder has been stuffed with plasticine, and it seems that someone did it deliberately.

He frowned, smashed open the fire hydrant next to him, took out the fire extinguisher inside, and smashed it into the iron lock. One blow, two blows, and finally on the third blow, several fixed parts of the lock were smashed.

He kicked the door open, however, there was a locked-in isolation door inside.

"Worry-free, are you in there?" He banged on the door and shouted inside, but I don't know if it was too soundproof or for some reason, there was no response from inside.

The health data on the mobile phone shows that she is now in a coma, is this the reason, so no one answers?

According to the theoretical analysis, she was here, and he didn't know if it was actually the case, but he had a gut feeling that his girl must be behind this door.

He came running in a panic, carrying no tools, nothing but his phone and keys.

Of course, a combination lock like this is likely to lock up if it is violently disassembled.

Fortunately, all the security systems in this school are based on the code model framework he gave, and it is not difficult to unlock this combination lock.

He took out his mobile phone, connected to the school's intranet, and quickly entered the door's internal security code through the initial security behind the initial security

The whole process took less than a minute, and he solved everything.

However, he still felt that he was too slow.

There was a click, like some kind of metal clashing, and the door opened automatically.

A dull and damp smell greeted him.

Dong Zixu, who saw the scene inside the door, really laughed angrily, giving so much money to the school, but the equipment was still so backward, and the chemical storage room did not even have an emergency contact device.

If something really happens to her, don't think about it!

Dong Zixuan squinted his eyes and glanced around, in the dim space, her girl, leaning against the wall, was already unconscious.

He hurried over, and when he made sure that there was still a pulse, he picked her up and walked out.

In any case, go to a place with normal oxygen levels first.

He carried her to the hallway, took off her coat and laid her on the floor, made her lie flat, unbuttoned her neckline, and did chest compressions while doing mouth-to-mouth artificial respiration.

While doing first aid, he felt that some power was spreading uncontrollably in his body, leaving him in a state of vague and tense contradiction.

Trembling, he tried his best to keep himself calm.

As early as when he found out that her physical signs were abnormal, he had already contacted the hospital, and it should not take long for an ambulance to arrive.
