"Hmm."

Chen Mang didn't speak further. For example, a Level 1 train can create a white accessory called "Single Bed," but it's just a single accessory, not a "Single Bed Production Line." After a moment, he suddenly laughed.

This time, the harvest was indeed good.

The train "Ten Steps, One Kill" gave him this card, which was truly useful. Without this card, Biaozi and the others couldn't have entered this laboratory.

The "2D" train also brought him to a good place.

These two are good people; if there's a chance in the future, I'll offer incense to both of them.

Oh no, wait, the former isn't dead yet, so we'll talk about it when he's gone.

Although that equipment can't be used for now, as long as he collects enough experimental data and finds a large number of scientific researchers, one day he can create and design the accessories he wants himself.

...

As for the story that happened in this experiment, it's quite simple.

A long time ago.

Or maybe not too long ago, Biaozi was looking among the residents for a forensic expert to perform an autopsy on those human corpses and see roughly how long they had been dead.

This laboratory was ordered to study the blueprint for the "Cardiac Stimulant Injection Production Line."

But because it involved biological experiments.

During the experiments, it was easy to create some extremely terrifying monsters. This had happened many times before, so to prevent such situations, the military base was set underground, and many heavy weapons were placed on the surface in case terrifying monsters were created and escaped from the experimental base.

And inside the experimental base.

The glass laboratory at the core of the deep plaza had a very high level of defense, so in case of any issue, the bombs buried in the walls of the entire laboratory corridor would all detonate, burying all the monsters deep underground.

Meanwhile, the researchers and experimental data could survive in the laboratory, awaiting rescue.

Later...

Later, indeed, some problems occurred, but it wasn't an issue within the laboratory. The city was subjected to a devastating attack by countless monsters, turning the entire city into a monster playground, and all creatures were slaughtered.

This laboratory, buried deep underground, escaped the calamity.

However, having lost contact with the outside world for a long time, the monkeys used for experiments began to mutate, killing the assistants and staff outside the laboratory. The despairing researchers who couldn't get out or wait for rescue chose to commit suicide.

But the experimental data and equipment remained preserved.

This is the whole story of the underground secret laboratory, and inside the lab equipment, there hides an AI, which Ai mentioned is a "Scientific Research AI." It has no human emotions and only calculates data. Once the equipment is restarted, this "Scientific Research AI" can awaken again.

"Phew..."

Chen Mang exhaled a sigh of relief, stretched his body, and continued to maneuver the Constant Star Train flying in the air towards the next anomaly on the map.

This was his first time seeing humans in the ruins of the Mechanical Civilization.

He originally thought the Mechanical Civilization only consisted of robots, but now it seems there are humans as well. However, who holds the dominant position in this civilization, humans or robots, remains unknown.

It doesn't seem like humans.

At least if humans built the city, it shouldn't look like this.

All the office buildings almost look the same, with a dark black color from the streets to the skyscrapers, all roads are extremely straight and standard, with no greenery or parks.

Extremely dull and monotonous.

This doesn't align with human aesthetic perception.

Even if it was initially designed as a refuge city, it shouldn't completely ignore residential qualities, right?

The train continued forward.

Soon, it arrived at the second anomaly, located at the city center.

It was a deep pit.

The pit was approximately a hundred meters in diameter.

...

Chen Mang maneuvered the Constant Star Train to fly in the air, slowly descending into the pit, with incandescent lights embedded in the pit walls. It wasn't very deep, probably around a hundred meters.

At the bottom of the pit, he saw a missile standing on the ground.

Seven meters long and three meters wide.

It seems the yield is not very large, and next to the missile, a light screen appears.

-

"A nuclear bomb capable of destroying the entire city."

"Press the red button to enter a countdown of 10 seconds for detonation."

"Detonates immediately after 10 seconds."

-

He found it; this is the mission target of this map.

However, Chen Mang's face had no happy expression, instead expressionlessly looking around, which was empty, the deep pit plaza had nothing but this missile and a button on the pedestal beside it.

Escape?

Where to escape?

It didn't even give him a direction to escape, and 10 seconds isn't enough to escape anywhere.

After a moment.

Chen Mang silently ordered a team to stay on the plaza to guard, while he planned to check the third anomaly point to see if there was an escape route. He was very grateful he cleared the map first.

Otherwise, with such a massive weapon just exposed here.

Anyone pressing it would take him to the grave.

How unjust it would be for him to die like that.

At least put a cover on that button; he is worried that if a monster suddenly shows up and falls, hitting the button, how unfortunate would that be. Leaving a team there to guard, preventing random things from moving the button.

He went to look for an escape route.

The third anomaly point was extremely far from the second one, with a straight-line distance of about thirty thousand meters.

...

The Constant Star Train slowly stopped in front of a tunnel.

The tunnel was entirely made of glass, starting from the ground, with about a thirty-degree arc, piercing straight into the top of the underground space.

This tunnel was the escape route.

From a high-altitude view, it's quite prominent among the rubble at the back of the city.

-

"Super High-speed Train Tunnel."

"After inserting a Level 3 Energy Stone, the train will levitate using magnetic suspension in the center of the tunnel and escape this city at super high speed, rushing out to the surface."

"In a damaged state, it can only allow one train to pass through."

-

This is the escape route in this Adventure Map and also the pre-established escape route when the city was first built.

Which means.

No matter if he chose to clear the map at the start, only one train can pass through, and four trains are destined to die here.

In the future, he must try to avoid venturing into the Adventure Map with Er Dan.

He really doesn't want to have a death match with a friend, and Er Dan probably hasn't experienced this type of Adventure Map, or else he wouldn't have so casually come along.

Moreover—

This "Super High-speed Train Tunnel" is located at the edge of the city, extremely far from the nuclear detonation point.

The straight-line distance is a full thirty thousand meters.

It's impossible for the train to appear at the tunnel entrance ready to set off in 10 seconds after a nuclear detonation.

There's only one solution.

That's to choose a sacrificial person to press the nuclear button, and as soon as the countdown starts, the train enters the tunnel and prepares to escape.

Of course.

If following the idea of good things coming in pairs, you can choose two sacrificial people for a bit of fortune.

"It's really big."

Getting off from the train, Chen Mang stood on the vacant ground, looking at the not-distant underground city, and couldn't help feeling a bit sentimental. Although he didn't know how many meters underground it was, to excavate such a large space underground and build a city in it.

The infrastructure capability of this Mechanical Civilization is quite strong...

...

"Mountain Cat, what do you mean."

Sitting inside the mecha, Biaozi lowered his gaze towards Mountain Cat with a somber expression: "It's not your turn to play hero; what are you doing pretending here? Put the gun down!"

"I said put the gun down, did you hear me?"

Mountain Cat, standing on the plaza with the gun barrel aimed at his own head, his eyes red, croakily said.

"Biao."

"We both know well what the situation is now."
