"How is this possible?"

Zhang Min said in disbelief at first.

Qin Shuying's lips trembled, pointed to the ground next to the two corpses, and said:

"But the impossible happened, and that's our footprints."

Zhang Min and Qianqian hurriedly looked over, and sure enough, they saw a pile of messy footprints next to the two corpses, which were left by the straw sandals of several people.

Qianqian was a little devastated, she was ready to face danger, and even lose her life, but the thought that she would be trapped here and starve to death still shattered all her mental preparations in an instant.

"Yun Qianfeng, let's go back, I'd rather be killed than starve to death, and in case no one chases you here, then we can live well on this island, let's go back to the ship and repair it into our home, and we will accompany each other to live, okay?" We're all so beautiful, and you're the only man here, and we can only marry you, so it's not worth thinking about going back? ”

Yun Qianfeng smiled bitterly and said:

"We can't go back, we're back here seamlessly, do any of you see the exit? No, it's a closed loop. ”

Qianqian hurriedly said:

"We must have neglected it, shall we go back and try? I remember these two dry bones are not far from the entrance, no more than twenty meters, let's go back and try? Please, Yun Qianfeng, I'm not afraid of death, but I'm afraid of dying like this. ”

Yun Qianfeng thought that it would be better to go back and try, if he could really return to the entrance, whoever wanted to go back to the ship would let them go back, and how to enter the depths of the island by himself could only find another way.

So he nodded and said:

"Okay, let's go back and try it, everyone keep your eyes on it, and don't miss anything that could be an exit, especially the shadows."

Zhang Min and Qianqian nodded again and again, Qin Shuying gave Yun Qianfeng a knife-like look, and Yun Qianfeng was so shocked that Yun Qianfeng hurriedly grabbed Qin Shuying's arm and kept a distance from Qianqian, and the four of them immediately turned around on the spot and walked towards the way they came.

However, this walk is only a few hundred meters, and there is no exit in sight.

This time, they walked slowly, taking in almost every inch of the road, but they were sure that there were no missed forks in the road.

They did not believe in evil and continued on their way until they saw the mountain of dry bones again.

Not to mention Qianqian now, Zhang Min is a little broken.

With a crying voice, she said:

"Oh my God, it's really a closed loop, a closed loop without gaps! We're trapped inside. ”

With no way to move forward and no way to retreat, Yun Qianfeng finally felt the despair of the Ninth Stonemason's Society.

Qin Shuying grabbed Yun Qianfeng's arm, tried his best to control his fear, and asked:

"So, that's how she and they ended up trapped here?"

Yun Qianfeng nodded, but only halfway, and immediately shook his head and said:

"They'll be trapped to death, but we won't, and I'll take you out alive."

So saying, he spread the donkey's skin on the ground, and beckoned to the women:

"Rest in place, we can't waste our energy, we must first figure out what is going on."

The third girl was at a loss, and when she heard Yun Qianfeng's words, she also knew that this was the best choice, otherwise she could only die of exhaustion.

So he sat beside Yun Qianfeng silently, trying to calm himself down, use his brain, and think about the causes of this closed loop.

But they are already in turmoil, and they don't even have the mental strength to calm down, so how can they think clearly.

Fortunately, the more extreme Yun Qianfeng is, the more calm he will become, just like in the miracle of Savage Mountain, seeing that everyone is about to be crushed to death by the collapsing stone cave, but he completely ignored the danger at that time, and only had a thought of finding the answer, and he should be afraid afterwards.

It's very zen-like.

Yun Qianfeng is back to that state now.

He lit a cigarette casually, took a shallow puff, tugged at a rib next to him, and began to draw on the ground.

The three girls next to them were also thinking of a way out, but when they saw the graphics drawn by Yun Qianfeng, they were uncontrollably attracted by those patterns.

Soon, he drew three patterns, one that looked like a square step, but the staircase was strange, it could go up or down, but it always came back to the original point.

The second image appears to be a twisted ring.

The third image is a bottle-like pattern with a hole in the bottom, but with an elongated neck that stretches and twists into the inside of the bottle until it joins the hole in the bottom.

The three maps are different, but they all have one thing in common, that is, they all form an infinite loop pattern.

Qin Shuying said curiously:

"These graphics are so weird, they all form loops that are almost impossible to live in the real world."

Yun Qianfeng pointed three patterns with the ribs in his hand and said:

"The first is the Penrose Ladder, which transforms the height difference into a plane, forming an infinite loop, a distortion of space. The second is the Möbius ring, which also uses space warp to unify the front and back of a plane into a single face, completing an infinite loop. The third is the Klein Bottle, where the two Möbius rings are docked together to form a body, which is the Klein Bottle, completing the infinite cycle of space. ”

Qin Shuying was already smart, and when she heard this, she hurriedly said:

"These three pictures are actually one picture!"

Yun Qianfeng nodded and said:

"That's right, three pictures are actually one picture. So this cliff tunnel must be in a space that is higher than three dimensions because of its distortion. That's why the cliff tunnel is a sinuous serpentine shape. ”

Qianqian looked at the three pictures for a while, and then said urgently:

"However, none of these three pictures have been exported! It's completely closed-loop. ”

Zhang Min raised his head and said:

"There is no closed loop, and it should be possible to get out from above."

She pointed to the hundred-meter-high cliff.

Yun Qianfeng shook his head and said:

"Not to mention that this mirror-like cliff can't be climbed, even if you can climb it, when you get to the top, I will go straight back to the ground, because the surface of the Klein bottle is circular in any direction."

Qianqianyi sat on the skin of a wild donkey, like a deflated balloon, and wailed:

"That means there's no way we're going to get out?"

Yun Qianfeng shook his head and said:

"As long as this is artificially created, there must be an exit, there must be a glimmer of life, we must have ignored something, something that is easy for us to ignore."

With that, he closed his eyes and began to recall every fragment of his entry into this cliff.

Qianqian and Zhang Min were more realistic, the two of them got together, snapped their fingers and whispered to recall the scenes of entering the cliff gap, not daring to speak loudly, for fear of disturbing Yun Qianfeng's thinking.

However, the two of them studied for a long time, and they didn't find anything they ignored, after all, this road had been walked twice, especially the second time they almost didn't pull an inch, looking at the people who came over, how could they ignore anything.

Qianqian whispered with a crying voice:

"I'll just say that there is a ghost in the whirlwind at the entrance, you see we are called a ghost to hit the wall and trap it."

Yun Qianfeng was thinking of a way out, and he was also puzzled, but when he heard Qianqian say "whirlwind", he suddenly opened his eyes, and there was a look of surprise in his eyes.

However, before he could smile, he saw several people, a woman and six men, walk in at the bend of the cliff not far away.

All in tight-fitting tactical black suits, with sabers and pistols pinned to their waists.

Yun Qianfeng knew that the person who was chasing and killing him had finally come.

He didn't have time to explain carefully, but pressed Qin Shuying's ear as fast as he could, and said in a voice that only the two of them could hear:

"The whirlwind is counterclockwise."

It's too late to say more, because those people are already near.

The woman who looked and dressed like Laura smiled and pulled out the pistol with a waist loop, opened the safe, and aimed at Yun Qianfeng's forehead
