At the moment when the two flashbangs exploded, Ye Fei rushed out, and the Star of Hope in his hand turned on the crazy point mode.

Poof! Poof! Poof! ……

The muzzle is slightly adjusted to fire, and each time a burst is fired, two bullets always make a headshot. That level of accuracy is even more accurate than installing a satellite positioning system.

At this time, Li Jiayi also rushed out of the room and threw a smoke bomb at the opposite side.

Mu Feng and the others also took out the smoke bomb to cover Ye Fei's retreat.

The four smoke grenades were thrown very horizontally, creating a wall of smoke and blocking the enemy's view.

Ye Fei also took out the red smoke bomb from his backpack, as well as the green poisonous mist ghost smoke bomb, and threw it out.

The six smoke bombs suddenly fogged the entire hall, and Ye Fei and the others quickly rushed towards the direction of the elevator under the cover of the smoke bombs. However, when he came to the elevator, Ye Fei asked everyone to stop.

There are two elevators in front of you, both of which lead to the lower one. But if you go down by elevator, if the enemy is prepared, the elevator is no different from a moving coffin. As long as the elevator reaches the bottom, as long as the enemy aims at the elevator, they will definitely be dumplings in an instant.

But there was no choice at all, and the enemy was already rushing from the other side of the smoke!

"Advanced elevator! I have a way! Ye Fei shouted and beckoned everyone to go in first.

The elevator doors opened, and five people slipped into the elevator.

At the moment when the elevator door closed, countless bullets hit it, splashing countless sparks and clanging.

Ye Fei started the elevator, but he didn't point to the next floor, but to the bottom.

There are six buttons in the elevator, one to the ground and the other five to the underground. In other words, this underground base has five floors.

When the elevator door closed, Ye Fei took out two handfuls of Thunder Fury, directly split the top of the elevator, and then squatted on the ground. "Quick! Step on top of me! ”

Everyone didn't think about it so much at all, they flew and jumped towards Ye Fei, and then Ye Fei also jumped up, pushing everyone to the elevator one by one.

When everyone went up, Ye Fei was pulled by countless murders and jumped to the top of the elevator.

At this moment, the elevator stopped at the mecha production line on the next floor.

At this time, in the hall of the mecha production line, hundreds of NPC soldiers were already fully armed and aimed at the elevator. And there are also two battle mechs, and the Vulcan cannon also has the fire control system turned on.

The moment the elevator door opened, everyone opened fire at the same time.

Da Da Da ......

Sudden ......

Bullets rained down on the elevator like a storm, creating a spark in the elevator. The elevator could not withstand the power of the armor-piercing bullet at all, leaving holes on it.

However, the NPC soldiers were all stunned, because the elevator was empty, and there was not even a human figure. What about people?

Just as they were stunned, another elevator came down, and the doors opened again.

Everyone shot wildly again, but the elevator was still empty, and they couldn't even see a single figure.

What about people?

Where the hell did the people go?

In fact, when Ye Fei got into the elevator, he paid more attention, that is, he first pressed the button of another elevator, and then started this one. It's just that after he entered this one, he lifted the top of the elevator.

Jumped on the elevator, and when the elevator stopped on the next floor, everyone jumped to another elevator. Immediately afterward, there were bursts of gunfire like popping beans below, which was so dense.

At this time, Mu Feng and the others threw themselves to the ground for the five bodies that Ye Fei admired, if it weren't for his caution, maybe they would have all hung up.

Since the other elevator and this elevator are in the same elevator shaft, and the top of the other elevator is not destroyed, Ye Fei and the others stood at the top of the elevator, and when the elevator stopped, he carried the Thunder Fury to the side.

Hiss!

The light flashed, and the barbed wire next to it was torn open, revealing a pitch-black hole. Here are the vents, which the enemy installed in the elevator shafts in order to save space. Ye Fei also saw it in that guy's office, with a flat map of the entire underground base.

The ventilation facilities in this underground passage must be perfected, otherwise people will die of lack of oxygen, let alone production.

Ye Fei was the first to jump into the ventilation duct, and Li Jiayi and others rushed in.

The space inside the ventilation duct is not very large, so you can only squat forward inside. There are many branches in the ventilation ducts, although Ye Fei has seen the floor plan, he still can't understand where those branches will lead. The ventilation ducts here are almost like a labyrinth, criss-crossed.

"Let's go, let's go to the bottom first." Ye Fei said, moving on. He didn't know where the branches led, but he knew the main passage.

Walking along the main passage of the ventilation duct, you will see a ramp in front of you, which extends directly downward. And from the pipe, you can see a flash of light in the distance, and there is an exit.

"If we slide down from here, we'll get to the bottom of the island, and then we'll figure out how to go up." Ye Fei said.

Everyone nodded, the matter has come to this, and it can only be like this.

Sliding directly down the passage, Ye Fei held the Star of Hope tightly in his hand, and the fighting nerves in his whole body became tense.

The angle of inclination of the pipe is very large, and the speed at which Ye Fei and the others glide is also very fast. The light ahead is getting brighter and brighter, and the exit is near.

At the moment when he slid out of the passage, Ye Fei only felt that his eyes lit up, and a huge cave appeared in front of him, and below it were piles of containers and many platforms.

The cave was simply too big, many times larger than the hall on the second floor. And the whole cave is brightly lit, so you can clearly see the surrounding scene. There are a lot of NPC soldiers in camouflage uniforms on those platforms, and they seem to be busy with something, and there are a lot of mechs working around. It's just that those mechs are not combat mechs, but engineering mechs, helping to unload goods or something.

Half of the cave is containers and work platforms, while the other half is seawater, on which two submarines are parked. Outwardly, these are conventionally powered submarines, not nuclear submarines.

The ventilation ducts are all containers underneath, and they are not very high. At the moment of landing, Ye Fei curled up and rolled sideways to remove the force of landing.

Touch!

At this time, Li Jiayi and the others also slipped down from the ventilation duct, but their movements were a little indecent......
