In order to save power, Zi Yang and the others turned the lights to the darkest level. From a distance, three small bright spots moved slowly in the boundless darkness like fireflies. As he walked, the old Wang knelt on the ground with a puff, "No, I can't walk anymore, I'm exhausted!"
"Take a rest!" Zi Yang was also exhausted, two battles.
Twenty hours have passed since Qin Xianghe detonated the explosive. Lao Wang, Zi Yang, and Su Rui were wading through the "mountains" in the dark and tortuous underground labyrinth. They couldn't remember how many waterways they crossed and climbed. How many times the rock wall.
Su Rui sat on the ground, took out an energy bar from her bag and handed it to Zi Yang: "The last one."
Zi Yang carefully broke the energy bar into three segments and divided them into one. Old Wang took his share and stuffed it into his mouth, and swallowed it almost without even chewing it.
Zi Yang put his piece in his mouth and chewed slowly. After chewing, he carefully rinsed between the teeth with the tip of his tongue, so as not to waste any residue.
After eating this energy bar, they really run out of ammunition and food.
"Did we go the wrong way? It feels like we've been walking for a long time, as if we've been in circles under the ground." Zi Yang's confidence began to shake.
Lao Wang also said: "That's right, at least I have walked a few hundred kilometers, why can't I see my head? If you go on, you will even walk through the earth!"
Zi Yang knows that a few hundred kilometers is an exaggeration, but there are always one or twenty kilometers.
The two looked at Su Rui together, wondering what this genius beauty thought about the current predicament.
Su Rui murmured with his hands on his knees, "I didn't expect this underground cave to be so complicated. What I am worried about now is not that there is no exit, but that we have stepped into the Mobius Belt."
"What is it?" Old Wang asked weakly, lying on the ground.
"The Mobius tape, a kind of physical model. The German mathematician Mobius found that after twisting a piece of paper 180°, connecting the two ends to form a paper tape circle, it will produce a magical effect. If you put a bug on it and let it walk along the strip of paper, it will never go to the end."
"What do you mean? I didn't understand." Lao Wang opened his two ignorant eyes with a dazed expression.
Su Rui drew a three-dimensional figure on the ground: "The ordinary paper has double-sided curved surfaces, one front and one reverse. But the Mobius belt has both front and back sides on the same side—or it has only one side, and the bug is on the same side. Walking up here will only repeat the cycle, but it will never reach the end—the Mobius ring has no end."
Zi Yang took a breath of air, "I see, you mean this underground labyrinth is a Mobius belt, and we are the bugs walking in it?"
Su Rui nodded solemnly.
Lao Wang stood up and stood up: "I don't believe that there will be roads in this world that are not going to go, what a mess! Just poke a hole with a pen, and go around in circles! Why are you doing so much? !"
Zi Yang sighed: "Do you think you are a pile driver? Do you have the strength of a king salamander?"
Lao Wang tilted his head and thought for a while. He really didn't have the strength, and he held his head in both hands and said distressedly, "Is that the end? Xiao Su, think of a way, aren't you a genius?"
Zi Yang also looked at Su Rui with hope.
Su Rui hesitated and said, "There is no way. Now we have several options: The first is to cross the border of the Mobius Belt."
"How to cross?"
"Like Lao Wang said, directly destroy the Mobius belt. But we don't have the proper tools, it's difficult to do this."
Lao Wang sighed and said, "Xiao Su, it's all here. Let's stop the popularization of knowledge, just say how to get around this broken circle."
Su Rui continued: "In terms of physical concepts, there is a most straightforward way to go out and find the place where the Mobius ring begins."
The question is where does it start? There is no street sign in this place! Zi Yang thought sadly.
Old Wang looked down and thought for a while, and suddenly his eyes lit up: "I know where it is! It's where the Overlord Salamander broke the wall, right?"
Su Rui nodded: "I suspect it is there, too, but I'm not sure."
Zi Yang said dejectedly: "Don't think about it, even if it is where it started, the question is can we find a way back? Even if we remember the way, do we still have the strength to walk back?"
The three looked at each other, obviously the answer is no.
"Xiao Su, Xiao Su, think about it, is there any other possibility?" Old Wang crouched beside Su Rui and asked anxiously.
"There is another possibility: this ring is not closed, there are other ways out."
"Are you sure? Don't coax my old Wang to toss around for a long time. I really can't hold it for that long. This broken submersible weighs at least a few hundred catties..."
"Keep going, at least we haven't encountered a repeating road yet, right?" Su Rui gave Lao Wang an encouraging look.
Zi Yang knew that they hadn't remembered whether they had turned back or not. In the dark underground space, most of the roads were similar. It's just that this kind of frustrating remarks are best kept in the bottom of my heart, because they are too bad for morale.
The three raised their spirits and staggered forward in the narrow and slender gap. Zi Yang raised his head and looked up. The gap became narrower as it went up. It seemed that the end could not be seen at a glance.
"No power! Grass!" Lao Wang patted the diving light on his head, and the diving light in Zi Yang's hand also gradually turned yellow and dimmed.
Su Rui adjusted the miner's lamp on his hand to a moderate brightness, barely able to illuminate the surroundings, and the three of them walked deep and shallow.
"Ouch!" Lao Wang suddenly exclaimed, and fell to the ground on his back. Because of the heavy breathing apparatus on his back, Lao Wang was like a bastard with a shell on his back. He stroked his hands and feet. He didn't even get up.
Zi Yang hurriedly stepped forward to help him, who would have slipped his feet, then slipped and fell.
Zi Yang only felt that his hands touched a layer of sticky on the ground. When he placed it in front of his eyes, it was dark and muddy.
"Stepped on oil?" Pharaoh finally turned over and said, looking at Zi Yang. His hands and body were also covered with black "silt".
Su Rui approached her nose and sniffed and said, "No, it's animal feces."
"Wocao!" Lao Wang and Zi Yang panicked and wiped the dung on each other's body. The hands are wiped clean, but the body is in a mess.
"Grass, what is pulling such a large piece of shit?" Old Wang said cursingly. Under the light, a layer of black shit could be seen on the ground.
"What you should care about is how this thing is pulled!" As Zi Yang spoke, the three of them looked up together. There are also scattered thin trails of shit hanging on the rock wall.
Su Rui turned the brightness of the miner's lamp to the highest level, and you could vaguely see tens of meters above it, as if something was creeping.
"Wocao!" Lao Wang sighed again, the thing on it seemed to be alarmed, and suddenly rushed down!
"My mother!" Lao Wang shouted, holding his head first. Su Rui and Zi Yang followed behind and ran desperately. In my ears, I could only hear the huge black shadow fluttering above my head, as if it was colliding on the rock wall.
Fortunately, this crack is relatively narrow, and the mysterious creature seems inconvenient to move in this small space, and can't catch up with them for a while. The three sprinted with their heads stuffed, and finally rushed out of the crack, and an open area appeared in front of them.
The three men lay on the ground, panting, and only felt it was difficult to breathe, and their legs were sore and swollen. This sprint consumed a lot of physical strength, and they could no longer run.
Fortunately, the monster did not chase out of the cracks. It seemed to be stuck in a certain position inside. Everyone only heard the sound of rattling in the huge cracks. It seemed that the rocks in the cracks were knocked and rolled down. Down.
"Oh my god, I, I really can't run or run anymore, just die, die here!" Zi Yang said weakly, lying on the ground, only feeling his heart beating like a drum. Venus scurrying in front of me, the two temples seemed to be hit with a small hammer.
"Why is it so easy to think and want to die? In case that monster catches you and raises you, eat little by little..." Lao Wang was saying, suddenly a strong wind on top of his head came down, and the three of them breathed stagnantly. , A huge black shadow with two claws had fallen behind Zi Yang, and abruptly grabbed him.
After catching Zi Yang, the monster flew upwards with a fan. Lao Wang and Su Rui were hurt by the strong wind from his wings, and Zi Yang's body was lifted up to ten meters in an instant. Lao Wang was in a hurry and couldn't care about anything else, so he took out the dogleg scimitar at his waist and threw it over.
The heavy dogleg scimitar drew an arc in the air, slammed into the monster's chest impartially. The monster screamed sternly, dropped Zi Yang and flew out more than ten meters obliquely, bumping its head against the nearby mountain wall and rolling down.
Su Rui rushed forward to help Zi Yang who had landed, and asked anxiously: "You, are you okay?"
Zi Yang fell from the air of about ten meters, was thrown into a dizzy head, and said breathlessly, "Why is he, his horse, I am unlucky again? Who am I to offend? He fucks me every day! Why am I so lost?"
Lao Wang ran to the place where the monster fell, and saw that the huge flying monster had broken its wings, turned its neck, and revealed its bones. The dog-leg scimitar was deeply embedded in its chest. Lao Wang couldn't help being darkened. Give a compliment: Lao Tzu is really a heroic martial artist, so accurate with just a single shake.
Seeing that the flying monster's chest and abdomen seemed to be undulating slightly, Lao Wang pulled out the scimitar and stabbed again. After confirming that the flying monster was completely exhausted, he ran back happily and shouted to Zi Yang and Su Rui. : "There is meat and some meat is eaten, I stabbed a big bat to death!"
Zi Yang and Su Rui looked at each other: Big bat? What kind of bat can catch a hundred tens of catties in the air
Su Rui came to the corpse of the flying monster with Zi Yang in his arms, and took a closer look with a miner's lamp. He was surprised: What kind of bat is this? It is obviously a gargoyle!
