The part on the ground is mainly used for defense and living, while the part hidden underground is used as a research center.

Most of the secret bases created by Hydra are like this. And this one hidden on the small island is no exception.

Of course, "there are research facilities below" is just a guess. Before a thorough inspection, no one can guarantee 100% that there are no organs set up by the enemy in the underground part.

"Concentrate and be careful." A part of the manpower was left to guard the entrance. After exchanging glances with Natasha and Hawkeye who had gathered together, Captain America took the lead and walked into the elevator.

"Count me in." After thinking for a while, Shi Xiaolei also stepped up to follow.

Although the technicians who came later have inspected the elevator and determined that there are no laser traps installed inside the elevator, in the final analysis, they only inspected the elevator, and they don't know what kind of thing is at the exit below. situation.

Considering that the three of the US team have not surpassed the scope of human beings, and the enemy is researching technology from aliens...

He just wanted to insure the three of the US team, that's why Shi Xiaolei took the initiative. Well, not really out of curiosity.

"..."

Seeing Shi Xiaolei entered the elevator, they looked at each other, the Prince of Wales, Nagato, and Mutsu quickly followed and squeezed into the elevator.

There is one thing to say, this elevator is quite big, more like the kind of large elevator that would be used in shopping malls when moving supplies.

But because the three Princes of Wales are all in combat mode, and they are still fully armed with naval outfits...

The raised cannon barrel hit his face, and Hawkeye couldn't help showing a wry smile: "That...Ms. Nagato, can you close your cannon a little bit?"

"Ah, sorry!"

Without the viciousness she had when cleaning up the enemies just now, upon hearing Hawkeye's words, Nagato blushed in embarrassment, revealing another side of her character involuntarily.

Because of this little episode, the originally serious atmosphere suddenly relaxed a lot.

The elevator began to descend. Natasha held a small instrument given by a technician in her hand, and observed the readings displayed on it.

When the elevator reached the bottom, the numbers finally stopped beating.

"210 meters." Putting away the small instrument, Natasha reminded the companions around with a slightly solemn expression: "Guys, if you have to do it later, take it easy. I don't want to be covered by the seawater pouring in." die."

"clear."

With a promise, Captain America set up a shield in front of him.

Shi Xiaolei also took a step forward, took out a tower shield covering a larger area, set it up in a similar manner, and stood beside the US team.

With a soft sound when the pressure was released, the elevator door slowly opened.

There was no gunfire as expected, and no one was even heard running or shouting. Except for the slight and almost imperceptible movement of the ventilation fan, the elevator was quiet, and there was no other sound.

"no one?"

Shi Xiaolei was the first to get out of the elevator because of his thick skin.

Following behind him, the three of the US team and the three ship girls also came to the hall with two rows of fluorescent lights.

"It's so peaceful, something's wrong."

"Um."

As experienced agents, both Natasha and Hawkeye have a very keen sixth sense. At this moment, both of them noticed that something was wrong with the atmosphere, and both of them showed serious expressions on their faces.

At this moment, in the hall that was originally very quiet, a rapid siren sounded suddenly.

The bright and white light also suddenly turned crimson.

"Not good!" There was a chill in her heart, thinking of a possibility, Natasha couldn't help but change her face, and quickly warned her companions: "They have activated the self-destruct procedure, get out of here quickly!"

Although I don't know how big the underground base is, how powerful the self-explosive device installed by the enemy is, and whether it will directly blow through the rock wall when it explodes, causing seawater to pour back. But one thing is for sure—if you don't leave before the explosion begins and stay here to search for the information left by the enemy, the consequences will not be much better.

"Hurry up, go back to the elevator!"

Not daring to be careless, everyone quickly retreated into the elevator.

"Damn it, this thing doesn't work anymore!" After pressing it several times in a row, there was no response from the elevator. Hawkeye punched the switch very annoyed: "The automatic program must have been set in advance, and it will be locked immediately after coming down..."

This is the only entrance to the ground.

The depth of the elevator shaft reached more than two hundred meters, and an automatic locking program was installed.

The self-destruct mechanism will not be triggered until the elevator comes down.

Combined with these settings, it is not difficult to see that this is a trap specially set for intruders. And judging from the thoroughness of this trap, it has to be admitted that this Hydra remnant party is really cunning enough.

"There is no maintenance exit above." The first time I looked up to check the top of the elevator room, Natasha gave the second bad news~lightnovelpub.net~ It seems that we have to hurry up and find another way out. "

Just when the US team was about to rush out to find another way out, Shi Xiaolei stretched out his left hand and grabbed his arm: "Hey, buddy, don't worry."

"You have a way?"

"Yes, I have a way to go out, but that's what I said before, no matter what you see in a while, please hold it in your heart and don't tell..." At this point, I met Natasha and Hawkeye. After thinking about it, Shi Xiaolei felt that it would be impossible to keep secrets for himself based on their position, Shi Xiaolei was suddenly discouraged, and his expression became depressed: "Forget it, forget it, just pretend I didn't say it."

"If you have anything to say, go out and talk."

"..." Shaking his head, Shi Xiaolei stretched out his arms without answering, "Give me your hands, hold me tight."

There was no time to ask this question, Natasha, Hawkeye, and Captain America put their hands on his arm obediently. And the three ship girls who had already guessed what Shi Xiaolei wanted to do put away their ship outfits before getting closer.

After making sure that the big guys were firmly grasped, Shi Xiaolei got the idea and led them out of the elevator.

Put these people in the ark first, and then come out alone, cut the thick metal plate with a sharp weapon, get out of the elevator, summon the Hot Wheels, and quickly go up the elevator shaft.

When he returned to the exit again, Shi Xiaolei went back inside the ark, and picked up the US team and others who had been in a daze for only ten seconds.

"Just now that was..."

"Boom!" Before Hawkeye could finish asking, there was a loud noise from below.

Accompanied by a burst of violent shaking, there was a burst of excitement from the exit of the elevator shaft, and then, a thick tongue of flame rolled out like a dragon's flame erupting.
