In the face of what Chu zhe said, the king of medicine asked, "but underwater, is this really OK?" Yao Wang is more curious about this.

"Second young master, this operation also needs power control. If you really put the bridge into the water as you say, once it enters the water, it is likely to leak electricity."

In fact, the problems raised by Yao Wang have not happened, but according to the current technology, these problems are no longer problems.

So Chu zhe said, "king of medicine, you are worried too much. Now the technology is very advanced. And now there are waterproof devices. It's very easy to control the stone bridge by using some waterproof devices. "

"What zhe'er said is not impossible." Chu Yinglong also agreed with Chu Zhe. After all, this stone bridge can't disappear out of thin air, so Chu zhe said that it's possible to put that bridge underwater.

"Do you think so, grandfather?" Chu zhe was also happy to hear Chu Yinglong's approval. Because he has no reason to support this idea at present.

It was dark outside, and Chu zhe didn't know if the bridge must be underwater. If he thought wrong, it was not impossible.

"I don't mean to believe that the bridge must be in the water. Even if it is placed in other places, the manipulation you said may also happen."

Chu Yinglong said, "since it is possible, it is very likely that there will be a control mechanism in this cave."

Since Chu Yinglong also thinks so, the king of medicine also thinks it is possible, "let's look for it. If the second young master is right, there must be a switch in this cave to operate the bridge."

"Yes, let's look first."

Three people looked into the cave carefully, and suddenly found that they could see through the cave at a glance. There was no equipment that they could not see. What kind of switch could there be on the bare wall?

"Old man Chu, the mountain walls are all formed naturally, and there is no trace of digging. Do you think the switch controlled by anything will really be here? "

Yao Wang is right. The cave itself is naturally formed at a glance. There is no trace of manual action at all, so those switches can't be put here.

But Chu Yinglong and Chu zhe both felt that the switch could not be put here.

"Portrait." Chu Yinglong and Chu zhe said at the same time.

Chu zhe looked at Chu Yinglong and Yao Wang, "at that time, we just looked at these portraits, never thought that there would be anything behind them. It's very likely that the trace of his cave excavation is behind the portrait. "

Chu Yinglong also agreed with Chu Zhe that they would do whatever they said, so they began to search everywhere behind the portrait.

"I found it. Here it is." Sure enough, behind this portrait, Chu zhe found a switch.

When Yao Wang ran over, he could not help sighing, "I didn't expect that he would hide the switch here." Yao Wang looks at the switch and receives it. It seems that he can't admit it or not.

Chu Yinglong also thought this way at this time. Apart from he LianBo, who else would do this.

Although we all know that he LianBo must have done these things, Chu zhe didn't understand. "Then I don't understand. He wanted to come in voluntarily. But why dig this cave and rebuild this bridge? "

The doubts in chuzhe's heart are the doubts of all of them. Now no one can tell exactly what kind of things it is for. Helian Expo has spent so much thought and done so many things.

However, it is not the time for them to think about these problems. Now that they have found the switch they need to look for, the most important thing is to leave here.

By this time it was dark. And today's weather is not very good, there is no star in the night sky outside. The whole night looked like a black curtain hanging on. I couldn't see my fingers. I had to be very careful when I walked.

And in such cool weather, Chu Yinglong and Yaowang are not suitable to stay in this cave to rest. So Chu zhe pulled the switch for the first time.

Sure enough, as he expected, there was some movement under the water. Soon, the stone bridge appeared in front of everyone. When the stone bridge was stable, Chu Zhe and two old people walked across the bridge carefully.

After all, the bridge has just risen from the water, so there are still water marks on the top of the stone bridge. If you are not careful, you may fall down and get hurt.

Chu zhe takes Chu Yinglong back to the house. "You don't have to worry too much, grandfather. I'll go to the cave again in the morning."

Chu zhe handed him a cup of hot tea to make Chu Yinglong's body warm. "I think that cave, if I try again tomorrow, should be able to pass directly to the opposite.

Chu Yinglong raised his hand and stopped Chu Zhe, "don't go. Don't go there for the time being. I don't know where it is. Don't act rashly for the time being."Yao Wang was a little unconvinced. He walked in the cave all afternoon today, but he didn't go outside. He kept spinning around in the cave. He was so angry that his lungs would explode.

"Why don't I just go over and have a look? We can't wait here. It's not a way. We are still waiting here when we know there is a problem there?"

Who knows Chu Yinglong even shook his head, "no! Though the mountain is not steeper than the back. However, it is also a barren mountain. We haven't been there on weekdays. You're so old. You'll run into danger if you have nothing to do. "

"Well, let me go. I'm young and have a lot of strength. I won't have a problem climbing up." Chuzhe is not only young, but also has nothing to do with fitness and climbing.

If Chu zhe himself climbed up to see the situation, there should be no problem. Yao Wang thought it was feasible, but Chu Yinglong still shook his head.

"Why? grandpa? I can Chu zhe puzzled asked, "grandfather, you forget, when I'm ok, I also go outside to climb.". I can

In fact, Chu Yinglong doesn't mean that he doesn't believe in Chu Zhe. If Chu zhe goes up alone, it may be just a small problem for him. He has no problem climbing up.

But Chu Yinglong knew that the mountain was not the one Chu zhe used to climb. Apart from the stones, there was nothing to block his sight. He could see the top at a glance.
