Three days later.

Most of the things Chen Jin bought were alive, and they were piled up on the ground.

"I can go over there today."

The portal on the toilet in the bathroom, he fumbled for several days, during which the game was not finished, he didn't watch an episode of the anime, and the otaku attribute disappeared all of a sudden.

If it weren't for the sake of safety, he would have gone straight over there.

Now the equipment is basically complete, first of all, put on the most important sealed protective suit with anti-radiation function, this thing is a bit heavy, quite clumsy, and there is a very ugly filter mask, like a pig's mouth, but this thing can't be worn without it, the circular pit opposite the portal, he immediately thought of a nuclear explosion, associated with nuclear radiation.

Nuclear radiation is terrible, it will make people suffer from all kinds of cancer, and the cumulative radiation dose is too much, and it is 100% death!

In addition to protection against radiation, whether the air on the other side contains poisons and whether there are deadly biological viruses also need to be considered.

In short, there is nothing wrong with being cautious, and being careless will accidentally hit GG...... This is the conclusion that Chen Jin has come to after playing RPG games for many years.

After putting on a sealed protective suit and a filter mask, Chen Jinxian stuffed some things into the portal, hung them with hooks, and stuffed them into another world.

For example, the sleeping bags and tents in the field, the large backpack full of snacks and mineral water, and the tools placed in the other two small backpacks, all of them were stuffed into it.

Then, put a safety rope more than five meters long and went down.

One end of the safety rope is connected to a fixed bracket in the bedroom, which is stuck in the upper part of the wall on both sides of the bathroom door, and the stability factor is very high.

The safety rope extends to the other end of the portal, and there is a suspension more than three meters above the ground, which is not very high, but jumping directly will definitely break your leg, and you must use the rope to slide down.

However, Chen Jin just put down a chair and reduced the hanging height from the ground.

In addition, I bought a three-meter metal folding herringbone ladder online, but the express delivery has not yet been delivered, so I can only use the safety rope on the spot first.

"Let's go, let's go!"

Chen Jin dragged the safety rope with both hands, leaned his body, stepped on the toilet with his two legs first, and then put it into his buttocks, and after his waist was immersed in the portal, the center of gravity finally changed, and a pull from the other world made his body involuntarily slide into the portal.

until he disappeared into the bathroom.

……

Another world.

It is still a desolate scene of yellow sand all over the sky.

Stepping steadily on the red lacquered chair, for the first time, Chen Jin was immersed in this world.

Taking out the physical instruments in a small backpack, Chen Jin made some physical measurements.

"The gravitational coefficient is 9.81, which is basically the same as on the other side of the Earth."

"The intensity of nuclear radiation is 15.6 microsieverts per day, which is 10 times the natural background radiation of the earth.

However, the intensity of this radiation is not very high, and it will not cause much damage to the human body, unless the total amount of radiation in a short period of time, more than 100 millisieverts, will cause harm to the human body.

And 100 millisieverts is equal to 100,000 microsieverts, that is, the radiation intensity of this world is increased by 17.5 times in order to cause a little damage to Chen Jin.

Therefore, Chen Jin can completely take off the protective clothing on his body.

But for the sake of safety, after thinking about it, he still didn't take it off, the radiation intensity in this area is within the safe range, but what about other places? If there was a powerful radiation source somewhere else, wouldn't it be fatal?

"The oxygen content of the air is 19.6%, which is a normal low level......

"The carbon dioxide content is 0.12%, which is three times that of the other side of the earth, and the greenhouse effect is very serious!"

"The air has a sparse microbial content and a relative humidity of 15%, which is a highly arid climate."

“……”

After testing all the data, Chen Jin came to a conclusion:

Can live.

Although there are a few things that are rather bad, under normal circumstances, humans can survive in this world.

There will be no sudden death of a "quack".

Of course, Chen Jin also has to confirm that the surrounding environment is relatively safe, and there are no unknown threats such as large beasts, zombies, and constructed mechas, so he can be considered truly safe.

You must know that he brought a baseball bat and a Swiss Army knife over, the physique of an otaku is not expected to be so strong, and when he encounters a powerful unknown creature, his first reaction is to run away, run away quickly!

Everything else is false, and life is the first important!

Looking around at the environment, Chen Jin planned to explore the surrounding area.

"The surface of the pit is all vitrified and there is nothing, go explore the side and see what you can find......"

A question was in front of him.

The big pit is a bit big, and he is in the center of the big pit, and if he wants to get out of the big pit and walk to the edge of the big pit, he has to walk at least four or five kilometers.

This is a short distance, and at the walking speed of a normal person, it will take about an hour.

So far, can you go?

Chen Jin remembered his 5,000-ocean windwalker electric scooter that he bought, with a maximum speed of 75 kilometers per hour and a range of 120 kilometers!

"Do you want to bring the Wind Walker here?"

Looking up at the safety rope hanging from the portal overhead, it was difficult to climb up.

"Forget it, let's bring the Wind Walker over tomorrow."

Chen Jin put on a small light backpack on his back and a metal cane in his hand, and walked towards the edge of the round pit on foot.

In a desolate and dim world, he walked forward somewhat awkwardly.

It was a five-kilometer journey and took a full hour.

In addition, I have to climb the slope, and I am tired and a little out of breath.

But barely within his reach.

Climb out of the round pit with some steep edges.

Standing on the edge of the round pit, Chen Jin stopped and looked back, and the huge round pit was in full view.

"At least the result of the explosion of a nuclear bomb with a yield of 5 million tons!"

Then he turned to look around the pit.

The scene in front of him, Chen Jin still wants to describe it in two words: desolate.

Except for the rocky Gobi and the yellow sand, there are no traces of animals or plants.

All I heard was the sound of the wind, which was stronger than the bottom of the pit, and sometimes it made people unable to stand.

Chen Jin decided to explore a small distance forward, not too far, to see if there would be any gains.

Look down at the ground.

Filtered windshield in the black and white field of view.

Stones, stones, big and small, are all stones.

Nothing other than stones is to be seen.

The scene is doubly monotonous.

After walking about a kilometer, Chen Jin planned to turn back, thinking that he would not find anything worthwhile.

Raising his wrist and glancing at the time on his waterproof watch, it would be night in two hours, and he had to hurry back.

Suddenly.

Out of the corner of Chen Jin's eyes, he noticed a flash of metal.

"What's that?"

He walked towards the flash, about fifteen meters, and in the middle of a pile of stones, he picked up a piece of metal fragments.

The material of the metal fragment appears to be some kind of steel product, with a very low degree of corrosion, the size of an adult's palm, and the surface still has a metallic luster, about 1 mm thick, very strong, and very strong.

Chen Jin kneaded it vigorously twice, but there was no change.

The metal fragment itself is extremely irregular in shape, with wavy bends and an amoeba-like appearance.

It was as if it had been violently impacted.

He took out a radiation detector and measured the radiation intensity of the metal fragments, and found that the radiation value had not changed.

Does not carry residual radiation.

Chen Jin put away the metal fragments, put them in the side pocket of his backpack, and turned around and returned to the bottom of the pit.

Before nightfall, he took off his bulky protective suit, folded it and threw it into the rain and wind shelter, and put it together with other belongings to form a makeshift "small camp".

In the end, he traveled lightly, grabbed the safety rope with both hands, and with the help of the movable buckle tied to his waist, he returned to the bathroom of his bedroom with a little effort.
