Although it was not midnight, it was already ten o'clock in the evening, and the density of patrols had become an hour, and the security services on the island were so confident that they probably thought that no one would go to the island in the middle of the night, and even if someone went to the island, it would be impossible to find anything, and this was a small resort island.

The blind self-confidence of the sticks has created a great convenience for the dragons, and it takes only an hour to patrol around, and a reinforced battalion can all land, of course, there is an hour's gap, which is enough time for the dragons to dive into the water to find out the underwater situation.

Before entering the water, Longzi thought that the stone door could not be tightly sealed, and he thought that it would even artificially create some small gaps or something, which was conducive to the synchronization of the water level in the hole and the outside sea water at low tide, otherwise, when the low tide, the water level in the hole was higher than the sea level outside, it would be easy to damage the door, and the same reason, the water level inside the high tide was not synchronized and the door would be subjected to very great pressure. In order to ensure the proper functioning of the door, especially the door rail, the water level inside and outside must be synchronized.

Sure enough, as Long Zi expected, before he got into the water, he sent out a crack in the door, and there were small holes and holes. The door is made with the same effect as the rock wall, potholes, concave and convex is inevitable, there are many man-made small holes on it, it is estimated that it is used to enter and exit the water, but the forgery is very good, and it is impossible to find it if you do not check it carefully.

Since there are seams, it will be easy to do, and next, it will be the time for the three major to show their skills.

Incense blower, hose, began to pour smoke...... Unlock.

The preparation was sufficient, so it took less than an hour from launching the water to opening the stone gate, and by the time he had all entered the tunnel, the patrol boat had not yet arrived.

It's going well, it's going to be unbelievably smooth, and it's all thanks to Chen.

Although the entrance and exit door is not very large, only three or four meters wide and three or four meters high, it is a large protrusion inside, built a bit like a small dock, and two small boats can be moored on both sides of the hole. However, it is different from the previous imagination, thinking that after entering the hole, it is a straight tunnel, but in fact, after entering the hole, there is a hall the size of a basketball court, the height is also three or four meters high, half of the hall is in the water, and it can be seen clearly from the water along the stone steps to the platform, which is a small pier. There are fortifications on the two docks, and there are several doors behind the fortifications, which should be living rooms, storerooms or something.

In the fortifications on both sides, the people on duty fell to the ground, and some people in the duty room were also fascinated. Fortunately, Xu San is here, otherwise, everyone will definitely eat bullets when they enter the door, and they may be beaten into a sieve before they even take a look.

The little stick still took a lot of thought.

But what about the authentic entrance?

Needless to say, after entering this hole, there is still a door to enter the tunnel, and unlike what was guessed, this alternate entrance designed by the designer is really ingenious. Once you enter the dock in the cave, you have to think hard to find the tunnel.

"Don't toss, use ultrasound" Chen Ming was originally a non-combatant, and he should stay in the cave above, but Long Zi said that the tunnel Ken will also have electronic defense, and it is not possible to do without Chen Ming, and besides, leaving him alone in the cave above is not necessarily safer than entering the tunnel together, so he came together.

Not to mention, he's here to help.

"The entrance is here, no wonder this duty room has such a big filing cabinet, there is really no silver here. Chen Ming found a remote control in the pocket of the guy on duty, pressed it lightly, and after a tick, the filing cabinet slid silently to the side, and a hole more than one meter wide and two meters high appeared.

Whew, I finally found it, this alternate entrance and exit design is really good.

"Let's go, the electronic alarm device is disarmed. Chen Ming said after a few operations on the computer in the duty room.

"There was a battery car in the warehouse next to it, and we drove in. "Longzi drove a special battery car from the warehouse is city.

Two people in one car, two battery cars glided silently under the dim lights in the tunnel.

The tunnel is not as dark and musty as imagined, but it is very neat, the air is also very good, although the lighting is a little dim, like an old-fashioned dim street lamp, but for this underground passage, it is very good.

The monitoring and alarm devices along the passage have all been manipulated by Chen Ming, and now they just need to move forward at full speed. More than a thousand meters away, in a blink of an eye, at the end, there is another door.

Long Zi had been prepared for a long time, and took out the remote control qi he got in the duty room from the bag and was about to open it, but was stopped by Xu San.

He beckoned to Chen Ming, Chen Ming naturally understood, took out the life detector and swept it at the door, there was no one behind the door, and there was no one within ten meters. The stick was still too confident, thinking that the security measures at the entrance of the cave were sufficient, and there were no more guards here, and if there were people behind the door, it would really be difficult to do.

The door opened quietly, and the purpose was a duty room, not that the stick was careless and did not arrange a guard, looking at the situation in the room, it should have been arranged by a guard, but I don't know where the guard went at this time.

Outside the duty room is a huge hall, and there are many computer instruments in the center of the hall, and some people are working nervously. The two halls are separated by transparent glass, there are signs at the door of the rooms, the rooms on the right are all laboratories, cultivation rooms, etc., and the rooms on the left are what are the dean's offices, doctor's offices and other offices, and it is really a huge research base.

Everyone was working intensively, and they did not find out that the base had been invaded by foreign enemies.

They trust their electronic alarm kits too much, believing that whenever an unregistered creature enters, the alarm will automatically alarm and automatically close the entrance. They didn't expect that a genius hacker came, and the security system had already been cracked.

"What should I do, attack it?" Ryuko asked for Xu San's opinion.

"Don't worry, this is not the core area of the underground research base, there should be a core area with laboratories and a living area. Xu San said.

"Over there, there's a passage over there, at nine o'clock, next to the security director's office. Xu San whispered.

"It seems that we have to make a big deal tonight, and if we don't put the people here down, it will be impossible to get through the hall and touch the entrance of the passage. "Ryuko has a headache.

"Brother Xu, is there a way to put down these bastards?" Chen Ming said.

"Try it, there is not much medicine, I don't know if I can fascinate everyone in this hall. Xu San began to operate his incense.

"It would be nice to know where their ventilation system is, just smoke through his vents. Ryuko said.

Xu San's ** is still very effective, with a faint fragrance of colorless smoke, every moment it fills the entire hall, and the people working in the hall seem to be extremely sleepy, and fall asleep on the workbench.
