Although they were separated by dozens of kilometers, when the explosion occurred, Wang Dong and Luo Qing both saw the rising fireball, and then heard the explosion.

It's low, but it's violent.

Apparently, Zhao Huang used a large drone, perhaps a small plane loaded with hundreds of kilograms of explosives, or possibly a helicopter.

Anyway, the explosion was very violent.

Not to mention a substation, even a strong fortress must have been blown up.

In fact, just after the explosion, the power went out in the laboratory.

Wang Dong and Luo Qing did not hesitate, and immediately sprinted towards the laboratory at a fast speed.

Crossing the perimeter line, rushing through the barrier, and entering the experimental area were not in trouble.

What the two didn't expect, or what Nicholas didn't mention, was that after the power went out, the gate to the east of the experimental area began to close.

Nicholas was indeed not wrong, it was a steel door with a thickness of 1 meter.

In addition, it uses a hydraulic actuator, so it closes automatically when the power is lost, or more precisely by the gravity of the steel door itself.

Because there is no electric motor drive, the gate does not close very quickly.

In addition, there are no guards near the gate.

Obviously, the explosion had just happened, to be precise, the power had just been cut off, and the guards in the experimental area had not yet reacted, so they did not have time to rush over.

Seeing that the door was about to close, Wang Dong quickened his pace, and his speed suddenly increased several times.

After rushing closer, Wang Dong grabbed the handle on the door panel.

Immediately afterwards, Luo Qing arrived.

After glancing at Wang Dong, Luo Qing slipped in.

Wang Dong didn't delay and hurriedly got in.

"Any idea how fast you started?"

"How fast?"

"I can't even catch up."

Wang Dong pursed his lips and didn't talk nonsense to Luo Qing.

The eastern entrance is next to the equipment area of the experimental center, which is the place with the least number of people, so Wang Dong and Luo Qing chose to enter from here.

As the door closed, the light disappeared in a flash.

Although there are emergency lights for evacuation, I still can't see my fingers.

Fortunately, Wang Dong and Luo Qing both have strong night vision, even if they don't use night vision devices, they can see the surrounding situation clearly.

Nicholas provided a map of the interior of the experimental base, which had been drawn decades earlier.

During the Cold War, the Soviet Union sent many intelligence personnel to find out the situation of the Alamos laboratory, and even instigated several laboratory staff to try to get the internal structure of the laboratory, and the construction map provided by Nicholas came from a former Soviet intelligence officer.

It's just that the lab has definitely changed.

After passing through the three passages, Wang Dong found that they were lost.

Not only has the laboratory changed, but it has changed dramatically, with many more forks in the road and some areas that are not marked at all.

Obviously, after the end of the Cold War, the United States is still engaged in construction here, adding a lot of underground facilities.

What to do?

That's when power was restored.

Wang Dong and Luo Qing didn't dare to hesitate, and immediately put away their guns.

Before entering, they changed into the uniforms of the base guards, and they all wore a pair of large sunglasses, covering most of their faces.

How long can it be hidden?

The two of them didn't know what to expect, but according to the plan, they should go to the security monitoring center next, where they should turn off the central computer in the base.

Why?

Only by shutting down the central computer can it be disconnected from the database of the intelligence security agencies.

As long as they can't be compared with the dangerous people in the database of the intelligence and security agencies, even if Wang Dong and Luo Qing are found, the security personnel of the experimental center will not regard them as dangerous elements.

The security center is at the south gate, which is also the main entrance to the experimental center.

Because there is also a monitoring system inside the experimental area, and it has been running since the power supply was restored, Wang Dong and Luo Qing controlled their speed, behaved no different from the guards, and tried to avoid the surveillance cameras they encountered, and did not show abnormal appearance.

Along the way, some staff members were met, but no one doubted them.

In fact, those researchers didn't look at them at all.

Here, apparently, the status of the guards is not high.

After passing through several passages, Wang Dong and Luo Qing found that they had not found the right direction at all, that is, they had never found a passage to the south gate.

This underground experimental base is simply an underground labyrinth.

After passing another intersection, Wang Dong immediately stopped.

In front of it is a security door with two guards armed with submachine guns, as well as an identification console.

"You two, stop!"

As soon as Wang Dong turned around, he was stopped by a guard.

In fact, when he saw the two guards, Wang Dong knew that something was wrong.

Why?

The two guards, armed with MP7 submachine guns, had a golden logo on their chest and a similar sign on their shoulders.

Obviously, this indicates that they have a higher status.

In addition, the guards operating on the ground, there are no such signs.

There is no doubt that those two guys are guards operating in the underground base, and this is a top-secret area, and ordinary personnel are not to be approached.

Wang Dong and Luo Qing wore the uniforms of ordinary guards and belonged to ordinary personnel.

In addition, the guards in the base must know the rules, so they will definitely not run around.

What to do?

Noticing that Luo Qing had already held the pistol, Wang Dong let out a sigh.

"I said, which department are you from? New here, why don't you know the rules? This is a forbidden area, and you are not qualified to come here......"

The guy, as he spoke, walked over.

Wang Dong didn't let him finish his words.

As he approached, Wang Dong suddenly turned around, grabbed the guy's neck, and grabbed the submachine gun on the guy's chest with his left hand at the same time.

"Poof—"

Almost at the same time, Luo Qing pulled out his pistol and opened fire on another guard guarding the door.

"Click-"

When Luo Qing killed the second guard, Wang Dong used his hand to break the guy's neck.

It happened so suddenly that the two guards didn't react at all.

"Keep an eye on the outside."

Wang Dong searched out an access card from the corpse, then dragged the corpse to the door, and put the guard's right hand on the palm print scanning panel.

The door opens and inside is a passageway.

The two didn't say much and dragged the guard's body inside.

Subsequently, Wang Dong took off the badge and epaulettes on the guard, as well as the MP7 submachine gun.

Fortunately, the uniforms worn by the guards were the same, except for the badges and epaulettes worn.

There's no place to hide the corpses in the passage, but there's not much to worry about now.

There are two internal guards guarding here, and there must be hidden secrets, maybe there is something Wang Dong is looking for.
