"Yes, miss."

The minion who had already jumped into the water climbed back again.

Back at the entrance of the cave, this guy had more blood coming out of his nose, and he couldn't help but bleed from his nose, and his body began to itch, so he couldn't help but scratch it.

When everyone saw this scene, they immediately concluded that what Zhang Han said was absolutely right, the water was really poisonous. Relying on the clever doctor in charge, otherwise, everyone will swim over like no one, and the end will be the same as the guy opposite.

At this time, the minions on the other side seemed to be unable to bear it. He jerked out his dagger and stabbed it into his lower abdomen, ending his life.

He threw himself forward and fell into the water.

Miss Nie saw it in her eyes and could only shake her head helplessly. She then looked at Zhang Han and said, "Doctor Zhang...... Next, you see what to do......"

Zhang Han spread his hands helplessly and said, "Yes, it must not be over...... There is no other way but to turn back and find another way......"

"Okay, then turn back the way you came!" Miss Nie said.

After a toss, the minions lost one person, but the guns and ammunition were not less.

They went back the way they came, crossing the previous pool and making their way to the steps of the entrance.

At this time, Miss Nie said, "By the way, the mechanism above has been closed...... Can we go up? ”

"Spread aside, I'll see if I can find the mechanism." Zhang Han said.

It is relevant if the mechanism is opened, but it depends on where it is. The position on the wall in the stone chamber above is obviously open, and the position at the end of the steps below should be closed.

On the surface, there are only two, but they are only superficial. Everything needs to be explored so that there can be discoveries.

Everyone stepped aside, and Zhang Han first walked to the end of the stairs, squatted down, and tapped it with his hands.

He quickly found a location with a hollow sound, which was supposed to be the location of the shutdown mechanism. He tapped along the hollow, but the hollow sound was quickly muffled by the steps.

Zhang Han observed the steps, which were made of blue-striped stone, not excavated dirt tunnels. From this, Zhang Han was faintly able to conclude that this mechanism was most likely buried under the blue-striped stone. This made Zhang Han have to sigh that the ancient mechanism was clever.

A mechanism like this, made with modern high technology, is not a problem at all. And the ancients were able to develop such a mechanism even when the technical conditions were backward, which shows how smart their brains were.

This mechanism is a mechanism that closes the gusset plate, and even if it is found, it is not very useful. The point is to find the mechanism that opens the gusset.

Zhang Han beckoned a minion to come over, using a searchlight to help illuminate it, and he went up the steps, knocking on the stone formations on both sides to see if he could find anything here.

When the owner of the tomb built this place, it was obvious that he had designed it to be a Jedi. Whether or not there will be a mechanism left is obviously difficult to say.

It took a long time to tap all the way up, and Zhang Han didn't find the location of the mechanism. Gradually, he came to the top, where the gusset was. Hit it again, but it still didn't work, it seems that this is really a Jedi down here, and there is no mechanism.

Zhang Han knocked the steel plate again with some unwillingness, and immediately thought that the thickness of the steel plate was about ten centimeters. The surroundings are all dirt, and there is no problem on the surface. But below, you can see the stone layers.

Judging from the position of the above mechanism, it is the position behind the steel plate is turned over, that is, this position is connected to the mechanism. And this position, too, is also a steel plate, which is difficult to shake. But there is one point, on the two steel plates connected together, there must be folding leaves, and the blades are fixed with nuts, as long as this is removed, the steel plates will naturally fall.

After observation, it is not difficult for Zhang Han to see that the leaf boards are quite thick, and the nuts on them are even smashed to death inside. The way that future generations can think of, the people who made the mechanism in the first place obviously also thought of it.

The mechanism is gone, and if you want to break down the door, you can use some violence. Smashing with howitzers and blowing up with bombs are all ways. After all, there are these things in Zhang Han's system storage compartment.

It's just that he didn't have to do it, and Zhang Han didn't plan to show it yet.

Zhang Han went down with his minions, came to Miss Nie, and said, "Miss, the agency has not been found, if you want to get out, you need to use strong means." I thought it would be much easier if there was a weapon that sharpened iron like clay. ”

"A weapon that sharpens iron like mud...... Miss Nie turned her head to look at Qiu Mohan.

Qiu Mohan immediately took out a dagger and said: "This dagger is very sharp, but I don't dare to say that it can sharpen iron like clay, but ordinary things can be cut off." Doctor Zhang, what do you want to do, I'll go with you. ”

"Okay, let's go up and try it first." Zhang Han said.

He took Qiu Mohan back to the top of the steps, stretched out his hand and pointed to the folded leaf between the two steel plates, and said, "If you can cut this open, then there will be no problem." ”

"I'll try!" Qiu Mohan raised the dagger and poked it the leaf board.

No, this leaf board is really hard enough, Qiu Mohan came several times, except for hearing the sound of "dangdangdang", he didn't hurt a bit.

"This thing, it doesn't seem to be a puffy metal...... I can't cut him with this knife......" Qiu Mohan said helplessly.

Zhang Han also saw it, no wonder there was such a big flaw left in the gusset, it turned out to be confidence in the metal plate.

Zhang Han observed again and looked at the position behind the gusset. This location is actually connected to the location where the wall of the mechanism is opened. According to the principle of the mechanism, there must be a connection to open the mechanism.

However, this location is currently a stone wall, and if you can chisel through the stone wall and blast it, you may be able to destroy the mechanism directly. In this way, the gusset may open automatically.

Zhang Han said: "Then you can try to make a hole in this stone wall." ”

"Okay." Qiu Mohan agreed, and he did it.

The stone walls here are obviously not ordinary stones. Fortunately, Qiu Mohan's dagger, although it can't cut through the metal, can still chisel out the hole little by little for the stone.

With his unremitting efforts, he forced a hole in the stone wall that could be the size of a fist.

"How? Is it enough? Qiu Mohan asked.

"Bigger...... At least five or six grenades could be cramped in. Zhang Han said.

"Okay!"

Qiu Mohan continued to move.

Zhang Han walked down and asked people to prepare grenades. Of course, this kind of thing, Zhang Han deliberately pretended not to understand very well, pretending that he had just watched the grenades connected on TV, knowing that this could increase the power. But it's up to you how you do it.

Miss Nie's minions are naturally good at this matter. Immediately someone made a small bomb out of five grenades, which could explode at the same time. (End of chapter)
