The tunnel is not very wide and can barely accommodate four people walking side by side.

Under the illumination of a large number of torches, the originally dark tunnel was illuminated like daylight. Walking there, apart from feeling a little depressed, I didn't feel uncomfortable at all.

Chen Ze was walking at the front, and from time to time he would find small red flags either stuck on the ground or nailed into the mountain wall.

After being possessed by Cheng Yu, Li Quan'an used his insight to clear the way. All the untouchable places in the tunnel were carefully marked out. Even when he encountered a fork in the road, Li Quan'an carved an arrow on the ground to point to Chen Ze.

Point out the direction.

With Cheng Yu around, the defensive tunnels as dense as a spider web could not play their intended role. It was an unexpected surprise that his military skills could be used as a radar user.

Every time he found a small red flag, Chen Ze would carefully order the soldiers to pass on the order and let the people behind him pay attention to avoid it.

This matter was related to the lives of everyone present, so everyone had to be careless. When the soldiers saw the little red flag, it was like seeing the source of the plague, and they were afraid to avoid it. No one dared to challenge themselves and took a side trip to Hushan.

drama.

Even if there was a fool, he would have been pinned to death by his companions and rubbed madly.

Marching like this, although the team of 30,000 people was stretched very long, it was still in an orderly manner, moving silently through the intricate tunnels, and the speed was not slow.

As Chen Ze walked, he unfolded the map in his mind, always observing the movements of Li Quan'an, who could not be seen ahead. At the same time, the terrain in the defensive tunnel was slowly revealed due to Li Quan'an's movement.

What surprised Chen Ze even more was that the map actually had three-dimensional sensing. On the road they passed, blue dots representing the enemy troops flashed from time to time. The most exaggerated one was that they ran into a large dense area, which almost made the whole person.

The map turns blue with a large number of blue dots.

Chen Ze knew that Zhu Yan's army must be on the ground where they passed, but he didn't expect that the tunnel was dug so far.

He walked around in the tunnel for almost four hours, even stopping to rest once. Just when everyone started to feel a little dizzy, Chen Ze finally saw the little red dot representing Li Quan'an on the map.

Come down.

Looking at it now, I saw that they were already extremely far away from Bo'an City, perhaps more than twenty miles away.

And although the journey was winding and winding, the route was away from Bo'an City, passing directly through the camp of Zhu Yan's army, and in the opposite direction, reaching the enemy's rear.

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

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

Chen Ze thought for a while and saw that there was no red flag warning here, so he simply explained, hurried a few steps, and ran over with a torch.

Not far away, he saw Li Quan'an standing alone in front of a mountain wall with his back to Chen Ze. When he heard footsteps behind him, he turned back, as if he knew that the person coming was Chen Ze, and bowed slightly: "My lord.

, there is no road ahead.”

"No way?"

Chen Ze raised his brows, but heard the faint sound of water in his ears. After walking a few steps, he saw the sparkling water reflected on the mountain wall behind Li Quan'an.

"My lord, you will know it at a glance."

Li Quan'an also waved his hand in a gesture of invitation.

When Chen Ze saw it, he 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 confirm it just from the map.

Apart from here, the map didn't show any other passages. When they walked around here, there was only this road.

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

Although there is no map for the defensive tunnel, it is also a life passage for high-level people in the city to escape. Others do not know the details of the tunnel, but Zheng Yuanyun will definitely know it.

But there were too many issues that he needed to consider at that time, and Zheng Yuanyun was not an easy person to get along with, so he forgot about it as soon as he came and went.

Unexpectedly, the thing he just ignored became his current problem.

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

"There's nothing special here, and I don't see the problem."

At the end he added another sentence.

Insight can reveal weaknesses, so Li Quan'an can find hidden points of support, but there is nothing he can do about this stagnant water.

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

"Looks like we still have to get into the water."

Finally, his eyes fell on the pool.

This exit will not lead to a puddle for no reason, the key is probably at the bottom of the water.

He also did what he thought of, and was about to jump immediately, but was caught by Li Quan'an, who said urgently: "Master, why do you need to put yourself in danger?"

"Is...is everything okay?"

Chen Ze smiled bitterly, but Li Quan'an just refused to let him go, as if he was afraid that he would run away unprepared, and kept holding on until the soldiers behind him arrived.

In the end, scout Chen Ming took over the task, tied a rope to his body, and jumped into the water.

After a moment of silence, he popped his head out of the water, took a deep breath, and then rushed to Chen Ze and others who were watching above: "Sir, this is really the exit!"

Everyone worked together to pull him up. Chen Ming lay on the ground wet and drew a sketch from memory.

Chen Ze only took one look and suddenly understood.

No wonder this defensive tunnel is not allowed to go out, but it turns out that the key point is here.

They were indeed near a lake, and they were actually at the bottom of the lake.

The sketch Chen Ming drew on the ground is very much like a crooked S-shape, and this pool is the top of this horizontal S-shape. To dive into the water from here, you need to go through a short winding waterway, and then you will go straight up.

Rising from the bottom of the water to the surface of the lake.

This underwater channel is dug extremely deep. According to Chen Ming, it is just at the limit of holding one's breath for ordinary people. With a little patience, most people can float directly up.

And people can float up underwater, but if someone wants to dive into the underwater channel, due to the buoyancy of the water, the speed of diving will inevitably be slower than the speed of floating, and it will be difficult for someone to persist until they dive in.

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