The tunnel is not wide, and it can barely accommodate four people side by side.

Under the illumination of a large number of torches, the originally dim tunnel was illuminated like daylight. During the walk, except for a little depression, it didn't feel so uncomfortable.

Chen Ze walked in the forefront, and from time to time he found small red flags in front of him or inserted on the ground, or nailed to the mountain wall.

Li Quanan, who was possessed by Cheng Yu, used his insight to clear the way. All the inaccessible places in this tunnel were carefully marked out. Even when he encountered a fork in the road, Li Quanan also drew an arrow on the ground to show Chen Ze Point out the direction.

With Cheng Yu, the defensive tunnels dense as a spider web can't play the role it should be. His military commander skills can even be used as a radar envoy, which is also a surprise.

Whenever he found a small red flag, Chen Ze would carefully order the soldiers to pass the order down, so that the people behind would pay attention to avoid it.

This matter is related to the lives of everyone present. Everyone cannot be cautious. When the soldiers see the small red flag, they are like seeing the source of the plague. They are afraid to avoid it. No one dares to challenge themselves and take a trip to Hushan. The drama.

Even if there were two stunners, they would have been crushed wildly on the ground by their companions.

In this way, although the team of 30,000 people was stretched very long, but it was orderly, and the speed was not slow in silently moving forward in the intertwined tunnel.

While walking, Chen Ze unfolded the map in his mind, observing the movements of Li Quanan, who could not be seen ahead. At the same time, the terrain in this defensive tunnel was slowly revealed by Li Quanan’s movement.

What surprised Chen Ze even more was that the map was still three-dimensional. On the way they passed, blue dots representing enemy forces flashed by from time to time. All maps have turned into a large number of blue dots.

Chen Ze knew that this must be the place where they passed. Zhu Yan's army was on the ground. He didn't expect this tunnel to be dug so far.

I walked around in the tunnel for almost four hours, and even stopped in the middle and took a rest on the spot. When everyone started to get a little dizzy, Chen Ze finally saw the little red dot on the map representing Li Quanan and stopped. Down.

Looking back at this time, they were already extremely far away from Boan City, afraid that they would not be more than twenty miles away.

And although the road was winding around, the route of travel was along the far away from Bo'an City, passing directly through the place where Zhu Yan's army was encampment, and walking backwards to the enemy's rear.

Judging from the map, the place where Li Quanan stopped should be a small lake. On the ground above his head, there were no longer small blue dots.

There is a lake but no one, is it...

Chen Ze thought about it for a moment. Seeing that there was no red flag warning here, he simply confessed, he hurried a few steps, and ran to the past holding a torch.

Before walking far, he saw Li Quanan standing alone in front of a mountain wall with his back to Chen Ze. Hearing footsteps behind him, he turned his head back, seeming to know that the person here was Chen Ze, and his body bowed slightly: "Lord Lord , There is no way ahead."

"No way?"

Chen Ze raised his brows, but he heard the faint sound of water in his ears, and when he walked a few steps, he saw sparkling water on the mountain wall behind Li Quanan.

"The lord knows at a glance."

Li Quanan also waved his hand and made a gesture of please.

Chen Ze took a look and immediately understood why there was no way.

The place where Li Quanan was standing was indeed the end of the road, but there was a pothole at his feet. Looking inside the hole, the sound of water came from the pothole.

"How could it be water?"

Chen Ze frowned.

He knew that there was a small lake outside the passage, but the exit was actually blocked by the current. Could it be that...

"Are you sure this is the exit?"

In fact, there is no need to ask Li Quanan, Chen Ze can be sure from the map alone.

Except for this, the map did not show where there was a passage. They only had this way when they walked around here.

Only then did Chen Ze realize that he had neglected to ask Zheng Yuanyun about defensive tunnels.

Although the defensive tunnel does not have a map, it is also a life passage for high-level people in the city to escape. Others don't know the details of the tunnel, but Zheng Yuanyun will definitely know.

But there were so many issues that he needed to consider at that time, and Zheng Yuanyun was not a good friend, so he forgot about it.

Unexpectedly, what happened to be ignored became his current problem.

Li Quanan shook his head slightly, answering Chen Ze's question.

"There is nothing special here, and I can't see the problem."

At the end he added another sentence.

The first opportunity of insight can see where the weakness is, so Li Quanan can find the hidden support point, but he has nothing to do with this stagnant water.

Chen Ze thought for a while, beat and beat on the surrounding mountain walls, but found nothing.

"It looks like you have to get into the water."

In the end, his eyes fell on the waterhole.

This exit won't get out of a puddle for no reason. It is estimated that the key lies in the bottom of the water.

He also did what he thought of, and he was about to jump right away, but was pulled by Li Quan'an and said anxiously, "Why do the lord take the risk?"

"Is this... okay?"

Chen Ze smiled bitterly, but Li Quanan just refused to let him go, as if he was afraid that he would run away while he was not prepared, and dragged him desperately until the soldiers behind came.

In the end, scout Chen Ming led the errand, tied a rope to his body, and jumped into the water.

After a moment of silence, he popped his head out of the water, gasping for breath, and Chen Ze and the others, who rushed to the side to watch, said: "My son, this is really an exit!"

Everyone pulled him up together, and Chen Ming lay wet on the ground and drew a sketch based on his memory.

Chen Ze only glanced at it and suddenly appeared ~lightnovelpub.net~ No wonder this defensive tunnel is allowed to go out and not to enter, but it turns out that Guanqiao is here.

They are indeed near a lake right now, and they are actually at the bottom of the lake.

The sketch that Chen Ming drew on the ground looks like a crooked S-shape, and this pool is the top of the horizontal S-shape. To dive into the water from here, you need to go through a short bend of the waterway, and then it will go straight up all the way. Rise from the bottom of the water to the surface of the lake.

This underwater channel was dug extremely deep. According to Chen Ming, it happened to be stuck at the limit of ordinary people's suffocation, and most of them can directly float up with a little patience.

And people can float up at the bottom of the water, but if someone wants to hard dive into the underwater channel, due to the buoyancy of the water, the speed of the dive will inevitably be inferior to the speed of the ascent, and it is difficult for anyone to insist on diving in.

Even if there are, there are definitely not many, and it is difficult to form a climate.

What's more, the passage at the bottom of the lake did not seem to have been discovered by the Zhu Yan Empire. There was no blue light spot on the map that Chen Ze had been paying attention to.
