Reading the top soldier king of the book nest network 220: Let the two of them hold the switch Li Mengman was walking while observing, when someone suddenly shouted: "Look, there is a hole here!" However, it's not very big, it's the size of only one person! ”

Everyone walked towards the place where the voice came from.

"Don't go down yes! Wait until you've surveyed before you go down! Li Mengman stopped the man, for fear that he would rush down in order to grab the merit and be in danger.

The expert and Li Mengman arrived at the mouth of the cave. The expert took out the instrument and fiddled with it for a while, and said, "According to the drawings, it should be this cave." ”

Li Mengman looked at the entrance of the cave, and then looked around, she found that this cave was indeed very peculiar, if it wasn't for walking to a distance of five meters from the entrance of the cave, she wouldn't have found the entrance to the cave at all.

"Test the hole for any hazards." Li Mengman said.

"There should be no problem with this hole, it won't be suffocating inside, you can see that the plants at the entrance of the cave are luxuriant, and there are a lot of small animals crawling." Experts say.

"Who's going to go down first?" Li Mengman asked.

"Li Yongjun, you go down first! Be careful. Deputy Director Zhang pointed to the sentry who stood guard on the first night.

"Yes." Li Yongjun replied that he was about to go down to the cave.

"Wait." Experts say.

Li Yongjun looked at the expert, not knowing what he commanded.

"Come, tie this rope." The specialist pulled out a long rope.

After Li Yongjun put on the rope, he entered the cave. After a while, Li Yongjun shouted in the cave: "Come down!" It's so wide here! ”

Li Mengman looked at the expert.

The expert nodded towards Li Mengman.

"Deputy Director Zhang, do you think this arrangement is good? Let eight people stand guard on it, and the rest go down, do you see you lead the team to stand guard, or do you go down? Li Mengman looked at Deputy Director Zhang.

"Do you need so many people to stand guard?" Deputy Director Zhang asked puzzled.

"There's really treasure in the cave that you can't run away. Safety is paramount. Li Mengman said.

"Good. Listen to you. I'll choose eight people to stand guard, and you can take them down. You've all listened to me! Those who go down must absolutely obey Director Li's orders! Violators will be killed! Do you understand? Deputy Director Zhang Fa Wei said.

"Got it!" More than a dozen people answered.

A dozen people descended to the cave one by one, and sure enough, they saw a wide flat land. Li Mengman also came down, he admired the expertise of the experts, and there was really a river at the end of the platform.

Li Mengman looked around, and the river cut off the way forward. The platform could be seen at a glance, and she looked around and saw that the treasure could not be hidden around the wide platform. Is the treasure going to be transported through the river of the cave? Although the water of the river is not fast, it flows slowly, but, strangely, after flowing to the other side of the cave, the water does not know how to go?

Li Mengman walked over and took a look, feeling even more strange, the water flowed to a lower place, but at the end of the water was the cliff of the cave, if the water flowed further down, the water should become very rapid, why was there no movement on the water surface? Does the water seep down? Shouldn't it be so fast to infiltrate? The water in front of us is not fast, but it is not slow either!

Li Mengman looked at the expert.

The expert looked intently at the rock wall, and he muttered, "Strange, is there a mechanism under the current?" So where is the switch of the mechanism? ”

The expert's prompt made Li Mengman start to look on the rock wall. Her eyes lit up suddenly, and she noticed a strange round stone, slightly protruding.

"Do you see if that's a switch?" Li Mengman pointed to the slightly convex round stone and said.

"Quite possibly! However, people can't reach it, so it's better to try. The expert said.

As soon as the expert's voice fell, Li Mengmeng suddenly moved her feet a little, and her body flicked up, only to see her hand pressed towards the round stone, and only heard the sound of "whoosh".

Li Mengman fell back to the same place, and suddenly accelerated his speed in the river, but after a while, the commotion was gone, and the speed of the water quickly returned to its original appearance.

A smile appeared on the corner of Li Mengman's mouth, she knew that this cave did have a mechanism. A cave with a mechanism is an unusual cave. Only such caves will hold treasures.

More than a dozen people saw Li Mengman's chic movements just now, and all of them showed surprised expressions, and the change in the flow of water surprised them even more.

"You all saw it when I first opened it, and the stone I pressed was a switch, and if you press the switch, the water in the river will flow down quickly, and we may be able to pass through the river." Li Mengman said.

"Director Li is right, this river is just a shallow river, the switch is equivalent to a sluice, we opened the sluice, let the water flow down, and then we can go over to get treasure." Experts say.

Li Mengman stretched out her hand again and tried the water in the river, feeling the water was biting cold, she knew that if a person swam over, she would be cramped by the cold at any time.

Li Mengman shook the water in his hand, looked at the two tall men and said, "You two come here." ”

The two walked to Li Mengman's side and looked at her. The two couldn't help but sigh in their hearts, such a delicate beauty has such good kung fu, it's really amazing, no wonder they can be the director.

"You two stack Arhats, the person above you press the switch, and I'll see how long the water can go down." Li Mengman said.

"Yes." The two replied.

"You squat, you're on top." Li Mengman pointed to one with a big waist and a thick waist to make him squat, and the other stood on her shoulder and held down the stone.

Don't worry, you two, I'm next to you, and I'll be fine.

"It's fine." Both replied.

After a while, the person above held down the round stone, and only the sound of water was heard. Everyone watched as the water on the surface of the river slowly moved downward.

After about five minutes, you can see the bottom of the water. However, the water is still half a meter deep. There is also about half a meter above, that is, the river is about a meter deep, while it is more than ten meters wide. How to cross the river? Li Mengman thought about this question.

"Look here!" Someone shouted.

Li Mengman walked over to take a look and smiled. It turned out that there were also stone bricks in the river, and large stone bricks were lined up on the other side of the mechanism, about a meter away from the rock wall on that side. The stone bricks were apparently arranged artificially across the river. It seems that this cave has been carefully designed by man.

The stone bricks have come out of the water, that is, people can pass.

Li Mengman thought that as long as the two of them held the switch here, the others could go over. After the person has passed, the person who has the switch can come down and rest. After the people over there finished their work, they were about to come out, and the people here pressed the switch again, and the people over there could come over again five minutes later.

Li Mengman looked at the expert.
