As long as the radiation dose does not exceed 30,000 microsieverts per hour, for the modified Chen Yang, it is equivalent to irradiating an X-ray, and the impact is almost none.

Of course, if ordinary people enter here without wearing protective clothing, they are completely looking for death.

Walking along the stone wall, in the deep tunnel, only the sound of armor activity and stepping on the ground could be heard, and the rest did not even hear the sound of a mouse, the deep silence was terrifying.

"Hey, that's ......"

Chen Yang frowned and walked over cautiously.

Unexpectedly, the seemingly long and bottomless tunnel actually came to an end, and under the strong light of the two searchlights, it could be clearly seen that a train that had turned out of the track was lying quietly on the concrete wall of the tunnel.

It is only fifteen or sixteen meters away from Chen Yang at most!

"It's ...... Subway tunnels? ”

Chen Yang suddenly understood, and when he walked out of this cave that was more than 500 meters long, he looked back and saw that this cave was excavated from the cement wall, which looked quite strange.

But the most important thing now is not to delve into the origin of the cave, but to derail the train!

Just from the appearance of this derailed train, Chen Yang understands that it is not a Chinese subway car, and there is no domestic subway car with this shape......

Moreover, when did a train have an accident in the country, and it will not be dealt with for such a long time?

Yes, when Chen Yang's searchlight shines through, you can see that the train is not only full of dust, but also has a lot of cobwebs, and you can see that it has been abandoned for a long time.

The window glass of the derailed train had already been shattered by the violent collision, and Chen Yang was wearing exoskeleton armor and could not enter the carriage, but just looking inside from the outside, there were no corpses or useful items, and there were only dust and cobwebs in the emptiness.

"Strange ......"

Chen Yang walked three carriages in a row. Still nothing.

The derailed train has seven carriages, and along the track, there is a tunnel that is pitch black without the slightest light, Chen Yang has exoskeleton armor, and he is not afraid of getting lost and the dark, after walking through the train, he walks towards the depths of the tunnel.

"Just from the desolation of Cheng dù here. It's been at least twenty years or so...... Where will the subway be abandoned for twenty years? ”

The subway is generally one of the core public transportation of the city, and once there is an accident, it will definitely be repaired and inspected immediately, and it will never appear regardless of more than 20 years.

What's more, if the derailed train is left to lie there, what will happen to the other trains?

There is only one case left, and that is the subway line for some unknown reason. It was directly abandoned by the government.

It stands to reason that the subway line was abandoned by the government?

Chen Yang didn't know, even if he had a few guesses in his heart, before he got the evidence, it was just a guess after all.

After walking nearly 600 meters of tunnels, the surrounding desolate and dilapidated conditions became more and more serious. In addition to the damage to the high-voltage power lines overhead, even the surrounding cement walls were pitted, and large areas of cement rubble were everywhere.

"Hmm, this is?"

Chen CCTV's line froze, and the picture automatically enlarged the image in the distance, and several dusty bullet casings appeared in front of him.

The system automatically calculates the caliber of the shell and immediately displays the results on the left side of Chen's CCTV line.

"5.56*45mm?"

This bullet is the standard rifle cartridge of NATO (naTo), a brass cartridge. The copper bullet is armored, and the lead core is used by the United States and NATO system firearms, including the M16 automatic rifle and the M249 machine gun.

There are many firearms with this kind of bullet, and although Chen Yang still can't tell what kind of specific firearm is left, he still has an ominous premonition in his heart.

Inside the subway tunnel, you suddenly see a bullet casing left behind by a rifle or machine gun. This definitely does not bode well.

Chen Yang picked up the warheads and put them in the sealed box, searched everywhere again, and found a total of 57 5.56 mm shells on the surrounding ground, as well as bullet holes and traces of blood on the cement wall.

Obvious. I don't know how many years ago, there was an encounter here, and the battle should have been sudden, and neither side expected it...... But the battle soon ended.

Someone must have died here.

There are no corpses, no dried wreckage, only bullet casings and traces on the walls, which still tell the story of the past.

"4215 microsieverts per hour......"

After checking the radiation level of the surrounding environment again, Chen Yang stored the videos and photos he had taken in sections.

"yes, alright."

Looking up at the deep tunnel, Chen Yang controlled the power exoskeleton armor and continued to move inside.

The general subway trunk line is more than a dozen kilometers short and dozens of kilometers long, and Chen Yang hopes that after walking a section of the road, he can find a platform to the ground, so that no matter how bad it is, he can find out where he is.

That hope was quickly dashed.

Turning a corner, Chen Yang was depressed to see that the tunnel in front of him was blocked by the collapse of the rubble, blocking his way forward.

"Bad luck."

With a sigh, Chen Yang looked carefully near the blocked passage, and if there was a gap, then he could get out from there.

It's a pity that the tunnel collapsed completely, firmly blocking every gap that might be there, not to mention airtight, but it's also a fact that flies can't fly through, let alone the huge exoskeleton armor.

There was no way, Chen Yang had no choice but to go back, return to the place where the train derailed just now, and then walk towards another tunnel.

From the time Chen Yang entered the light film to the time he started to explore another tunnel again, two and a half hours had passed, and he had experienced a lot, and his ability to adapt to the environment was very human, otherwise ordinary people would be crazy if they stayed in this dark tunnel for a few minutes, and where would they have the curiosity to explore deeply.

The condition of the tunnel on the other side was even worse than the one on the right, and before Chen Yang walked out of a hundred meters, he saw that the walls in several places had collapsed, forming several piles of rubble. Fortunately, it did not collapse directly at the top, and the passage was not completely blocked as before, leaving half of the gap, which was enough for the exoskeleton to pass through.

This time, after walking for about twenty minutes, the tunnel suddenly broke off in front of him, and the scene of the buildings in front of him was exposed to Chen Yang's eyes.

"Huh...... Here it is...... Platform? ”

Chen Yang was slightly surprised, and his face quickly sank again.

This so-called platform can only be barely seen from the outside, and I don't know what kind of explosion Cheng dù has suffered, not only has the tunnel in front of it been blocked, but even the platform has been buried nearly half.

Before, Chen Yang hoped to find the platform and reach the ground, but the hope became slim again, which made the surprise of the talent disappear without a trace.

"Woo ......"

Stepping onto the broken platform, Chen Yang first scanned his surroundings, and then landed on the station name mounted on the ceiling of the platform.

The green label was already polluted by dust, and under the illumination of the high-powered searchlights, only the line could barely be recognized.

“B1oomfie1dave。”

Chen Yang marked these two words, and the processor inside the exoskeleton immediately launched a search, and the results came out in less than O.1 seconds.

Well, it's all unrelated songs.

The storage number in the exoskeleton is only 4 TB, and it is impossible to store all the information in the world.

"Wait!"

Chen Yang's heart moved, opened the map of the world, and searched for these two words.

Sure enough, this time Shun Lì found the information he needed.

The meaning of these two words is the name of a subway station on Staten Island in New York!

"New York, USA?"

Chen Yang was stunned.

He actually crossed the entire Pacific Ocean from the East China Sea to New York on the east coast of the United States......

The light film can transfer the spatial position of the object, which has been confirmed, and it is not this point that Chen Yang was stunned by, but the name New York!

What is New York? When did the subway platform, which is still in operation in the world's leading metropolis, become like this?

Looking at the desolate appearance, the time must be ten or twenty years, which is obviously unreasonable.

Unless there is an error in the search for a place name.

Or is it......

"Host, what's wrong with you?"

His right hand was silent for a while, and then he woke up, and he noticed that Chen Yang's heartbeat was abnormal, and asked in a voice.

"Screwman, something is wrong."

Chen Yang explained the cause and effect in the shortest sentence.

"Are you guessing...... Are we not just spanning space, but also time? ”

The right hand immediately vetoed: "Impossible, traveling through time, this is also impossible in the few top civilizations I have seen." ”

"So what civilization made the cube?"

Chen Yang retorted.

Faced with Chen Yang's question, his right hand was also a little silent for a while, and after a long time, he said: "Anyway, time and space travel is too unbelievable, and you can't make a conclusion lightly." ”

The right hand obviously understands time better than Chen Yang, and because of this, it knows how difficult and incredible it is to go back and forth in the long river of time.

In the universe, the motion of an object can never cross the light, and even if it is close to the light, time will indeed slow down on the object, but it is also a relative state, and it is an irreversible arrow.

Relying on this method to enter the future, it is impossible to return to the past.

However, in the previous light film test, they have verified it many times, and the time flow on both sides is the same, and they can also go back and forth, which proves that this is by no means a time shuttle.

However, the universe is so big, there are so many civilizations and races, and the right hand knows that it is not omnipotent, so it does not dare to veto it with one bite.
