This underground maze is very large and very complex. It has been artificially transformed and looks the same in many places. If you walk around randomly, you will definitely not be able to walk out in less than a few hours.

Fortunately, there is a system to help.

He Panxin said: "Record the trajectory."

As soon as he finished speaking, the system replied in his mind: "The system starts recording, and the remaining time is 3 minutes."

A white void immediately appeared in He Pan's mind, and a red dot flashed there.

The red dot should be He Pan's position.

He Pan hurried forward.

A magical scene appeared, and as He Pan moved forward, the red dots in his mind also moved.

The trajectory after the red dot moves is recorded by a green line.

Without Fan Xuemei, the water level dropped a little, and He Pan was still walking much faster than before.

The maze is complicated. Some passages have a hole every one or two meters away. When they enter, they are another passage. In addition, after the hole wall is repaired, it looks similar. It is very troublesome to distinguish the direction and route.

But with a system, it's different.

As He Pan moved, the red dots were also moving constantly. At the same time, the green line behind the red dots was also changing directions.

In this case, He Pan will not go astray. If he goes wrong, he can quickly return to his original position.

Therefore, He Pan's efficiency has been greatly improved!

"There is still half a minute left in the track record." The system prompted.

When He Pan heard this, he quickly took out a notebook from his schoolbag, took out a pen, and drew out the figures depicted by the green lines in his mind.

A few seconds after the drawing was finished, the system prompted: "Time ends."

How great would it be if this was an unlimited record!

It's so troublesome to copy it in a notebook every time!

It seems that you really need to upgrade soon.

He Pan looked at the flood in front of him.

The water level has dropped significantly, only to the knees.

It should be easier to leave now.

He Panxin said: "Record the trajectory."

The system immediately said in his mind: "The system starts recording, and the remaining time is 3 minutes."

He Pan glanced at the map on the notebook and immediately walked forward quickly.

...

After the third time of the system, the water level is only as high as the foot surface.

He Pan can basically run in the maze.

The map on He Pan's book is already a bit complicated by splicing the third route with the previous two maps.

According to the map, He Pan returned to the place where he first left and found Fan Xuemei.

Fan Xuemei was still standing on the stone, staring at the entrance of the cave, waiting for He Pan.

"He Pan!" Fan Xuemei screamed when she saw He Pan, with a crying voice in her voice.

He Pan immediately ran to Fan Xuemei.

Fan Xuemei stood up and rushed to He Pan's arms: "What are you doing? You haven't come back for a long time. I thought you didn't care about me anymore!"

After saying that, Fan Xuemei hit He Pan's chest with her right hand.

"A mouse ran over here just now, scaring me to death!" Fan Xuemei said with some fear.

He Pan patted Fan Xuemei on the shoulder and said, "I'm going to find an exit! I have to hurry up, otherwise what should I do if the flood comes again later?"

After saying that, He Pan handed the map in his hand to Fan Xuemei.

"What is this?" Fan Xuemei asked.

"This is the route map I just took. It's so big. I've already traveled to two or three basketball courts as big as a basketball court and haven't found the exit yet. But don't worry, it won't take much time to continue like this." He Pan explained.

"I want to go with you!" Fan Xuemei pulled He Pan and said.

"Okay, but if you don't get to a place, you have to wait for me for a while, otherwise you will follow too slowly." He Pan said.

Fan Xuemei nodded.

He Pan pulled Fan Xuemei out of the passage together.

After walking a while, He Pan looked at the map and said, "You are here to wait for me, remember not to move! Three minutes, at most three minutes, I will come back."

Fan Xuemei nodded in confusion.

He Panxin said: "Record the trajectory."

The system immediately said in his mind: "The system starts recording, and the remaining time is 3 minutes."

He Pan glanced at the map on the notebook and immediately walked forward quickly.

...

Three minutes later, He Pan returned to the place where Fan Xuemei was staying on time.

"Let's go, follow me to the next place." He Pan said.

Fan Xuemei was a little confused: "How did you draw a map? Just run like that?!"

"Yes! Otherwise, what's going on? Confused?" He Pan replied.

"Okay, you're amazing!" Fan Xuemei said.

When he arrived at another passage, he asked Fan Xuemei to stand there and not move, and He Pan came out again.

...

Twenty minutes later, He Pan came back for the fifth time.

"I found the exit, come with me!" He Pan said excitedly.

"Ah? Really!" Fan Xuemei became happy.

He Pan pulled Fan Xuemei, looked at the map, and walked forward quickly.

Two minutes later, the two arrived in a passage, and at the end of the passage was an iron door.

He Pan pushed the door open.

The two of them walked into the big cave when they entered the door.

There was no one in the cave.

"Where is Zhao Xin? He won't have come out yet, right?" Fan Xuemei asked with some concern.

"I can't. I didn't see him at all. Besides, he has been here several times and must know where the exit is, so you don't have to worry about it." He Pan said.

Fan Xuemei nodded.

"I guess Zhao Xin left first, let's go too." He Pan said.

After saying that, He Pan pulled Fan Xuemei to the big iron gate at the entrance of the passage.

As soon as the switch was opened, the iron door creaked and opened.

"Woo!" The strong wind blew in with huge raindrops.

Unexpectedly, such a heavy rain would come in, and He Pan's T-shirt was instantly wet.

"Ah!" He Pan quickly closed the door.

"It's raining outside, we can't leave." He Pan said.

"What should I do?" Fan Xuemei asked.

"I can only go back and wait for a while." He Pan looked at his phone. It was just over two o'clock and it was still early.

"There is no signal here, so it's not enough to call, so I can only go back and wait a moment." Fan Xuemei looked at her cell phone and said helplessly.

The two returned to the empty cave.

"It's so cold!" Fan Xuemei said tremblingly.

After Fan Xuemei fell into the water, her whole body was wet. Although it took more than half an hour, the cave was cold and wet. In addition, Fan Xuemei had not exercised, so her body was still wet.

But it doesn't drip any more.

He Pan only wore a T-shirt on top. When the flood came, most of the T-shirt was wet and the pants under him were soaked.

However, He Pan has been running back and forth for more than half an hour, and has been exercising, so his T-shirt and pants are almost the same.

However, when the door was opened just now, a large piece of T-shirt was wet.

When I went back to Dao Cave, it was really cold.
