Soon, the first giant fell to the ground with convulsions, and then one giant after another began irreversible convulsions, and at the last moment of his life, the dying giant used all his remaining strength to straighten his body as straight as a steel beam, and then collapsed to the ground and fell silent.

"It's damn oxygen." He Jun took a deep breath of oxygen-rich air, and his chest was full of happiness.

Only when you lose can you know how to cherish, even if it is just ordinary air.

Although they are friends and foes, He Jun still mourns for the hundreds of giants struggling on the line of life and death for a second, but it is only a second, he has no habit of mourning for the enemy, he will only be happy to see it happen.

Silently counting down from five, when He Jun silently thought zero in his heart, he could no longer see an enemy who was still struggling, and as far as the eye could see, there were paralyzed corpses everywhere.

He Jun vaguely remembered where he had seen it, there was a high chance of suffocation**, presumably the smell downstairs at this time must not be very good.

"Oh my God!" Lin Kai's eyes widened in shock, "It's all his grandmother's death!" ”

Even if he wished that all the giants were dead, it still terrified him to witness such a tragic mass death.

The bandits are all ruthless, but generally speaking, they are petty fights, where have you ever seen such a big scene in front of you?

He Jun hurriedly instructed: "Lao Lin, there is a problem in this place, don't take off your helmet!" "I don't have time to explain to Lin Kai about the composition of the atmosphere and oxygen, just tell him what to do.

Lin Kai was stunned for a moment, and then nodded: "Got it." ”

He Jun let out a sigh of relief, looked up at the sky, and silently guessed what era this was.

He searched the deepest part of his memory, but he couldn't remember when the Earth's atmosphere was formed, only vaguely remembering that the increase in oxygen levels began 800 million years ago. And I'm not so sure.

In other words, the time difference between this place and modern times is at least 800 million years!

The number of 800 million years made He Jun tremble, and a galactic year was only 300 million years. This time trip suddenly spanned three galactic years at once, how the hell did that control center do it?

Shake your head to drive the shock away from your head. He Jun turned around and knocked on the car window: "Don't be awkward, drive the car back, stay inside and wait, I'll be back soon, understand?" ”

Nodding awkwardly.

He Jun beckoned to Lin Kai: "Lao Lin, follow me." ”

"Where?"

"Go down and get the suit." He Jun pointed to the all-terrain vehicle, "You can't go down without wearing that awkwardness, and so are the two of us." ”

Lin Kai grinned. Walk into the stairwell with He Jun.

At the beginning, I asked for protective clothing just casually, but I didn't expect it to be really useful one day, and even He Jun himself couldn't tell if he was prescient at the beginning, or if he was affected by some unknown factor like when he was exploring the spaceship.

Wearing power armor, the two of them were unable to open the door to the protective zone with their fingerprints as they normally would, so they had to call Kiki to help them open the door.

After returning to the protective area, the two of them went into the warehouse and returned to the rooftop with three sets of protective clothing as quickly as possible.

The all-terrain vehicle had stopped in the middle of the rooftop, and the lone man looked awkward and anxious. It wasn't until he saw He Lin and the others that his anxiety eased.

He Jun knocked on the window of the car as usual to explain, and hurriedly closed the cab according to He Jun's explanation. Start the life-sustaining device. The cockpit and rear compartment were immediately separated into two separate cabins.

He Jun dragged the car door and didn't open it, he glanced at the personal terminal, and was stunned to find that the ambient air pressure level was about 1.6 standard air pressure.

To put it simply, the interior of the all-terrain vehicle is currently under negative pressure, and the air pressure is pressing the door tightly, and it is strange that it can be pulled open.

He Jun had to point out awkwardly to increase the pressure in the car, and as the air pressure in the car slowly increased, the internal and external air pressure tended to balance, and finally opened the door.

And that's not all. If a person suddenly shifts from a high-pressure environment to a normal environment, the body will suffer from decompression sickness due to the sudden decrease in pressure. If you don't do it, you'll end up paralyzed.

He Jun didn't know what problems would arise in this process, but it must have been nothing good. Therefore, the interior of the car must be readjusted to standard air pressure in order to take off the armor.

Moreover, the carriage was filled with an oxygen-free atmosphere of unknown composition. In addition to adjusting the pressure, the gas in the rear compartment had to be drained and re-injected with a standard proportion of nitrox air to ensure that the two of them did not suffocate like the giants downstairs.

All in all, it was a very rigorous process, and of the three people present, Lin Kai was from the early twentieth century, and had no knowledge of this direction at all; Awkward dropped out of school early and had limited knowledge, and everything had to be handled by He Jun himself, and the results were repeatedly checked.

At this time, He Jun secretly regretted that he shouldn't have taught only one person in Awkward during this time - the only people he could fully trust in Building 14 were Lin Kai, Awkward and Qiqi who moved in together, and in addition to himself, only Qiqi was left with common sense in this regard.

He secretly made up his mind that he had to teach Kiki how to steer an ATV so that she wouldn't encounter this strange environment in the future.

After tossing for more than half an hour, the air pressure and air composition in the car finally reached the normal standard, and the two of them couldn't wait to take off the power armor with the lowest power, looked at each other, and laughed in unison.

After laughing, He Jun entered the cockpit, started the fixing program, and the grappling hook that was originally used for climbing suddenly popped out, penetrating deeply into the floor under the car, and after tightening the climbing cable, the car body was firmly fixed in the center of the roof.

He Jun then unfolded the photovoltaic panels on the roof of the car, inserted all the white batteries into the charging slot, and then returned to the cabin and closed the cockpit through the data terminal.

Lin Kai and Awkward had already changed into protective clothing, and the two of them helped He Jun put on protective clothing.

Geng Le prepared the kind of light protective clothing similar to chemical protective clothing, which did not have the function of isolating external pressure, He Jun and others had to gradually increase the breathing pressure while increasing the pressure in the car, until the pressure inside the car was equal to the outside of the car, and then carefully opened the height of the car and stepped off the all-terrain vehicle.

"This thing is a lot more stuffy than power armor." Lin Kai said sullenly.

"Be content, you, it's good to wear some of them." He Jun said.

He also felt uncomfortable with the hazmat suit, but there were only a few wetsuits left besides this thing, so he couldn't wear that thing, right?

Lin Kai glanced back at the all-terrain vehicle: "If only I could remove the equipment in the car." ”

He Jun laughed, and then suddenly suppressed his laughter strangely: "Think beautifully, don't talk nonsense, hurry downstairs, I'm dying of hunger!" With that, he walked to the stairwell. (To be continued.) )
