They chatted like this for more than half an hour and found that Lu Kangping and Ah Da still hadn't come back, Hanako said: "It shouldn't be going around in circles, let's hurry forward, maybe they are walking this way to inform us." ”

The team continued to walk forward, and after walking for a few minutes and still didn't see Lu Kangping and them, Li Yunfei asked, "Did they just leave and didn't plan to wait for us at all?" ”

Ah Er arrived: "I didn't hear them nearby, maybe they really walked away." ”

"No, if they find out that they are not making a detour, they will definitely come back and tell us that this tomb is really dangerous, and I feel that there may be some other variables!" Tang Chen walked forward as he spoke, and after walking for a while, Ah Er suddenly stopped in place and said, "Look at this! ”

Tang Chen and the others turned around and saw that the wall was where Ah Da had just made a mark, and Tang Chen was suddenly puzzled: "So now we are back to the same place?" ”

"No, why didn't they come back here?" Li Yunfei said.

Ah Er looked at the mark made by Ah Da and said, "Is it possible that they went to another road and avoided us." ”

Hanako looked at the lamps hanging on the wall and said, "It's also possible, you see, there is a relative darkness at the distance between every two lights, maybe we have overlooked some details." ”

Hanako took them a few steps forward, especially in the middle of the relative darkness and paused and groped for a while, as if there was nothing abnormal, and suddenly Ah Er said, "There is a voice! Suddenly everyone fell silent, and Ah Er moved left and right to listen to the source of the voice: "It's getting farther and farther away, it's the footsteps of two people!" ”

"It must be the two of them!" Li Yunfei said.

"That's right, the sound seems to be uphill to the south of us, and it's getting farther and farther away from us, and it's no longer audible."

"Southside." Hanako looked at the wall to the south and knocked on the wall to the south, which was absolutely 100% solid, and it was impossible for them to move in the wall: "Are you sure that the direction of the sound is south?" ”

"Of course." Ah Er also groped the wall like Hanako, but the confusion on his expression was the same as Hanako: "What's going on?" ”

Li Yunfei flew around and looked around: "Did you say that the road we are on is separated by a board......

"No!" Ah Er quickly refuted his idea: "Now if we say that we are at a point, then the trajectory of the two of them is getting farther and farther away from this point." He said that he had also made a sketch on the ground, which was probably it.

During the time he explained, the voice came out again, and this time the direction of the voice was north, Ah San asked them to stop talking immediately, and then drew the trajectory of the voice on the ground, which was basically a straight line, at this time Hanako said: "They are going in circles!" ”

"What?" Li Yunfei looked at the picture drawn by Ah San on the ground and said, "Are you listening to it accurately, how could they go like this!" ”

At this time, Hanako drew a circle on the ground, and then drew a circle on that circle that separated from it: "Now we should be on two circles, everyone is going in circles, and these two circles have two intersection points, so we can hear this sound here." ”

Ah Er looked at the picture drawn by Hanako and said, "It should be like this, there should be no place to go through this point, which means that the place that may lead to that circle is another intersection point." ”

Hanako agreed: "We don't know the size of these two circles now, so there is no way to determine where the other point is, so we can only go through it again to test the distance on our circle first, and then calculate the distance of the other circle according to the time when the two of them arrive here, so that we can find another point!" Ah Er, you and Li Yunfei and Tang Chen are waiting here, and Ah San and I will go to measure the distance. ”

Ah Er agreed, but had another idea in his heart: "But do you think there will be a third circle?" Then he added another circle to one side of his circle, which was also two points of intersection!

Hanako said, "Of course, there is also such a possibility. ”

Ah Er said: "So let's not separate now, it will be safer!" ”

Tang Chen looked around and saw that the candlelight around him seemed to be shaking, and he said: "We must not sit still now, we have walked around here a few times and have not entered another ring, and they only walked around once and walked into that ring, what does it mean?" ”

Li Yunfei chuckled: "What else can it be, it's all a matter of luck!" ”

Tang Chen looked helplessly at Li Yunfei, who was already sitting and basically had no energy: "Please, you should use your brain now, two people can do it and we can't, it means that the weight of two people can open the passage, but we can't." ”

Hanako looked at Tang Chen and smiled slightly: "It makes sense, so what do you mean?" ”

Tang Chen said: "I'm just guessing, I remember that you brought a rope, we can go with the rope, two people go forward, if you can really enter the next ring, others only need to pull the rope to find the intersection of the two rings!" ”

At this time, Ah San took out the rope from his bag and handed it to Tang Chen, and then said, "You go ahead, this old one is behind us!" ”

Only then did Li Yunfei stand up, Tang Chen handed over a look to Huazi, and Huazi gave Tang Chen a reassuring look and said, "It's okay, you can go, they can't do anything to me as an old man!" ”

Tang Chen nodded and looked at the two guys and said, "I don't care who sent you, if my master is injured a little, I want your life!" Saying that, a dazzling red light appeared in his hand, which made those two guys really a little jealous!

Tang Chen and Li Yunfei walked in front of them with a rope, and Li Yunfei said, "Is this rope long enough?" ”

"It shouldn't be a big problem to go around in a circle!"

After they walked for a while, Tang Chen suddenly said, "It should be almost a circle now, are we already in another ring?" ”

As soon as the words fell, a voice came: "Tang Chen? ”

"It's Lu Kangping!" Li Yunfei shouted in surprise.

At this time, Ah Da and Lu Kangping ran over and saw them and said, "The road here is very weird, and the two of us have been going around in circles here just now. ”

Tang Chen pulled the rope hard, but halfway through it, he found that the rope had been loosened, and when he pulled it over, he found that the rope had been cut by something, the design of this mechanism was really ingenious, Li Yunfei picked up the end of the rope and said, "The rope is broken...... What now, they don't know we're in another ring......"
