"mark?"

"I have thought about this, but how do I need to mark it?"

I looked at her in confusion.

"What good idea can you think of in your brain?"

Su Hanyue curled her lips.

I was speechless, but I was too lazy to care about her, but I heard Su Hanyue continue, "We can first draw up a meeting point, such as the place where everyone is now. This is the meeting point, and then we scatter and explore the forks around us. Each person is responsible for one. Every time we pass an intersection, we engrave a mark and a unified mark. If we encounter a dead end, we will draw a fork and other marks."

"In this way, every hour we will contact each other, return to the meeting point as a whole, and then share the route we explore to form the prototype of the map."

"After selecting the most promising one, we all walked over, and after we arrived at the designated position, we repeated the previous step, and continued to diversify and find the route to form a new simple map."

"In this way, every time we go to a place, we search for it, which can save time to the maximum extent. How about it?"

"good!"

After listening to Su Hanyue's explanation, Wang Zheng was the first to applaud, his face full of joy.

Qi Tianchuan pondered for a moment, nodded and exclaimed, "Yes, this is the easiest and most effective method at present."

“That’s.”

Su Hanyue looked proud and didn't forget to glance at me.

I smiled bitterly and shook my head. After this girl came in, she seemed to have changed her temper and started to confront me again.

"Okay, without further ado, let's start from here and mark the exit position first."

I whispered.

"I'll do it. Since it was my suggestion, let me start first."

Su Hanyue waved her hand and volunteered.

It was not difficult to go back and mark the mark on the exit. Naturally, everyone had no objection and nodded in agreement. Then, Su Hanyue took out a dagger and turned around and walked in the direction he came.

She first carved an arrow on the wall next to her, then walked forward, and every distance, she carved an arrow again, gradually moving away, disappearing from everyone's sight.

Su Hanyue went to engrave the marks, and everyone was not idle. After she walked away, I took out paper and pen from my backpack, and according to the memories in my mind, I drew a simple route, indicating the direction and distance of traveling from the entrance of the cave, entering the corridor.

"We'll set this place as the meeting point now."

I clicked on the paper, drew a sign, and then said, "When Xiaoyue comes back, we will set off separately. It is best for everyone to draw the route of the journey. When we get together, we can integrate a relatively complete roadmap."

"good."

Everyone nodded, and they all took out paper and pen to draw simple graphics as I was like. After a little preparation, they waited for Su Hanyue to return.

However, time passed slowly, Su Hanyue's figure was not seen. Everyone couldn't help but frowned slightly, and a bad feeling came to their hearts.

"What's going on? It's been so long, why haven't Su Hanyue come back yet?"

Wang Zheng muttered softly.

"Will you encounter any trouble?"

Xiaohe also spoke, "It took us about ten minutes to enter from the ground hole and walk here, but it has been nearly half an hour since Xiaoyue returned. Logically speaking, even if he is slow, it should be back."

Qi Tianchuan frowned and was also a little worried, so he simply took out the walkie-talkie and asked.

"Su Hanyue, you have received the request to reply. Haven't you finished it yet?"

"No, it's still a little bit too late. I'm looking for the entrance to the cave."

Su Hanyue's voice came from the walkie-talkie, and everyone breathed a sigh of relief, but immediately afterwards, the conversation below shocked all of us.

"That's good, hurry up, everyone is worried about you."

Qi Tianchuan said.

"Haha, everyone cares so much that I have only been away for four or five minutes. What's the hurry?"

Su Hanyue said with a smile.

"What?"

Hearing this sentence, all of us were stunned.

Even Qi Tianchuan looked unbelievable.

I grabbed the walkie-talkie and tried to calm down for a long time before I said in a deep voice, "Xiaoyue, look at the following table. What time is it now."

A moment later, Su Hanyue's voice sounded, "What's wrong at 16:00 p.m.?"

"One Sixteen?"

Qi Tianchuan and others silently looked down at the watch, but found that the pointer of their watch was, 1:40 in the afternoon.

I looked surprised and at first I didn't believe it, but after talking to Xiaohe and others, I had to believe this strange thing. The time between us and Su Hanyue was actually 24 minutes apart. What's going on?

After confirming this situation, my face turned extremely ugly for a moment.

"The flow rate of time is different. In addition to the space ban, is there a time ban? What kind of ruins is this? I have never heard of anyone who can set up a time ban."

Qi Tianchuan whispered in surprise.

“What should I do now?”

I looked up at everyone, and I was a little panicked at this time. Even after I started practicing Taoism, I had encountered many incredible events, but it was the first time I encountered such a strange thing.

Qi Tianchuan remained calm and whispered, "Don't explore for the time being, find a way to find Su Hanyue back first, and wait until everyone gathers together."

"I'll go."

I looked up at Qi Tianchuan, saw him nodding slightly, then took out the walkie-talkie and shouted to Su Hanyue, "Xiaoyue, how far have you gone?"

At this time, Su Hanyue also realized that the situation might not be right, so she did not continue to move forward. After a moment of silence, she replied, "It's about five hundred meters. Is something happening?"

"Yeah, it's a bit unexpected. Don't worry, wait for me in the same place."

I was afraid that she was too worried, so I didn't explain the situation directly. Instead, I looked at Qi Tianchuan and asked, "Boss, you are exploring with your mental power now, how far is the limit distance."

Qi Tianchuan closed his eyes and tried it, then said, "It's about one thousand meters."

"good."

I nodded gently. I tried it just now. My limit distance was 900 meters, slightly less than Qi Tianchuan. But this is not the point. The point is that within my detection range, Su Hanyue's breath was not sensed.

You know, in her concept, she has only walked five hundred meters.

Even if this five hundred meters is a straight line distance, it is impossible to escape my mental detection. After all, the mental search is all-round, and it is centered on me. All the space of nine hundred meters around me can be detected, but I did not find Su Hanyue. What does this mean?

Qi Tianchuan's attempt just now also clearly did not detect Su Hanyue's traces.
