After prying the stone door and opening the one-person-wide crack in the door, Ji Xiu first took out a gem from the scabbard, held the gem in his palm, and used the light of the gem to probe behind the stone door.

Behind the stone gate is an ordinary cave, which is not like being dug by manpower, but it can be clearly seen that the cave goes all the way down and seems to go straight to the ground. Ji Xiu took out another gem and threw it to Igu and said: "Put the gem in your trouser pocket, it can illuminate the range of three meters around you, patting the trouser pocket can make the gem dull, and patting it again can make the gem shine again, it will be as convenient as a flashlight." ”

Igu Yiyan put the gem into his pocket, and the light around him lit up, which felt very magical, and took the gem out of his trouser pocket, the gem was still just an ordinary jade with a texture, and it didn't shine, but the bright light around his body didn't know where it came from.

Lao Qin came over and analyzed: "This is the projection jade, it itself can emit light, but it can cast light in a distorted form, so you can't see it glowing, and the light is projected around your body." After all, light is also a kind of matter, and it can also be played with. "Igu has used Hime-so's gems and knows that these gems not only emit light, but also make all sorts of magical effects on light.

Ji Xiu said: "Well, yes, it is indeed a light jade, or I have improved it, do you want to have one." ”

"No, I have a flashlight, and the flashlight is no worse than the light jade. Lao Qin held a flashlight in his left hand, a gun in his right hand, and his mountaineering equipment, which looked very reliable, but his face was a little older, which made people a little worried.

After Ji Xiu was the first to enter the stone gate, he held the gem in his left hand to explore the way, the beam of light emitted by the gem was indeed no different from a flashlight, and he walked more than a dozen steps at the beginning, and he didn't feel unusual, Ji Xiu still felt very relaxed, but Igu was already struggling, and Lao Qin helped Igu to walk together.

Igu felt more and more difficult to walk, and the camera was getting more and more biased, and now the camera was almost shooting at the top of the cave. Igu pressed the barrage, saw a few barrages and said:

"Take the camera well, you can't see Ji Xiu anymore"

"It's dark here, it's so scary, I'm afraid that when the camera turns, I'll see a grimace"

"Barrage Protection, Demons Disperse"

"I'm out of breath when I walk these few steps, and the monkey with the camera is really rubbish"

"It's scary, will there be ghosts in this kind of place?"

"I feel that the monkey spirit with the camera is about to be unable to keep up, and Ji Xiu has gone far away"

"Is the monkey spirit scared, I don't know if I pee my pants?"

Igu looked at the comment barrage posted by netizens, and knew that he was not afraid, but he just didn't know why he felt more and more dangerous, and this danger came from the soles of his feet, like a sharp knife cutting the soles of his feet or calves.

"Ji Xiu!" Lao Qin Xian couldn't help it, and shouted at Ji Xiu in front of the cave entrance: "It feels very inappropriate." The voice echoed several times.

Ji Xiu stopped, he also thought the cave was strange, but he didn't know where the strangeness was. Even if he can hold on, but the two behind him can't keep up, and now I hope to have some clues to find out what's wrong with this cave.

Igu sat down, not too tired to walk, but too hard to walk on the flat surface. Lao Qin leaned on the rock wall, and his body had a very wonderful and familiar feeling, this kind of sensory experience, where had he experienced it once upon a time.

"Strange, I can't sense any other creatures or energy fluctuations, it doesn't look like a ghost is messing around. Ji Xiu carefully examined the surroundings of the cave and muttered, "Could it be that the cave is funny?"

"Ji Xiu, let's take a break. Lao Qin said.

"Are you tired?"

"Don't get tired ......"

"......" Ji Xiu was speechless, Lao Qin and Igu were very quiet, they rested because they were tired, why should they rest if they were not tired.

Seeing that I can't go on, is it just about to retreat after walking this hundred steps, walking into the stone gate has just begun, I encountered the difficulty of wanting to quit, I walked into the stone gate with confidence, and walked out of the stone gate without injury but with palpitations, can this be accepted.

What is the problem, Ji Xiu has been looking at the cave for a long time, and he can't see anything famous, maybe he can find out the reason further, but Lao Qin and Igu can't keep up, so it's better to let them stay where they are and go forward to check on themselves, which is not a bad way.

At this time, the flashlight in Lao Qin's hand fell off, and a magical scene appeared, the flashlight did not fall to the ground, and spun and fell in the direction of Ji Xiu. In this dim cave, the flashlight rotated in the air, and the beam of light rotated with the flashlight, shining on Ji Xiu's face at once, and Lao Qin's face at once, fighting at three hundred and sixty degrees.

Ji Xiu stretched out his hand and caught the flashlight that fell from Lao Qin, and his face changed, as if he had suddenly realized. Lao Qin couldn't help but say, "No, we are not walking in a parallel cave, but on a vertical well wall?"

"Not quite right, I should say that there is a double gravitational superposition here, this double gravity forms a cross shape, there is a vertical downward gravity, and in the depths of the cave, there is a gravitational force pulling us. It is because of the extra gravitational pull that we have such a difficult walk, I am afraid that the further we go, the more the cave will become a shaft. Ji Xiu touched the ground, more and more sure of his guess.

"Do we need to quit?" Lao Qin seized the opportunity to persuade.

Ji Xiu ignored Lao Qin and continued to explain: "There is not a single gravel on the ground, and there is no sand, which proves that the smaller the mass of the object, the more easily it is affected, and all the gravel and sand fall into the cave due to the unexplained gravitational pull in the depths of the cave. ”

"Shouldn't we quit?" Lao Qin reminded again.

"After knowing that gravity is the problem, what else is there to be afraid of, just run forward, we can quickly fall to the bottom of the hole. Ji Xiu ignored Lao Qin.

Lao Qin looked remorseful, walking in the flat cave, who knew that it would suddenly become to jump off the building, and now he finally knows what the wonderful and familiar feeling that his body feels, that is, he has a fear of heights, and the black entrance of the cave in the direction of Ji Xiu is the bottom, as long as he goes further, he will fall into it, who knows how high it is.

Ji Xiu jumped up on the spot, and after jumping, he would move more than half a meter forward when he landed, and said: "Look, what I said should be not much worse, that's what I mean, let go of your guts." ”

After Ji Xiu finished speaking, he continued to move forward, and Igu followed very firmly, and this time Igu followed not far behind Ji Xiu. Lao Qin didn't want to lose Ji Xiu, he had thought of a lot of plans to get close to Ji Xiu before, but he didn't expect Ji Xiu to let him follow so easily, such a good opportunity, how could he take the initiative to give up following Ji Xiu.

The direction of gravity has changed, and the most I can do is climb a mountain, and I'm full of gear. Thinking of this, Lao Qin leaned forward on the stone wall, and walked forward for another hundred steps, the soles of his feet were already suspended in the air, and he didn't know where Lao Qin took out the rope, maybe it was from his backpack. Tie the rope around your waist and lower yourself little by little.

Lao Qin looked at the bottomless black hole below, tied a flashlight to his waist, knocked out a stone on the rock wall with a shovel, and threw it down, and after several minutes he couldn't hear an echo, Lao Qin scolded his mother in his heart, Ji Xiu and Igu had disappeared into the black hole below, and they didn't know where they had gone, and they were still moving down carefully.

"Hey, Ji Xiu, where are you!" Lao Qin's voice was a little lonely, and the solid rock walls around him blocked his voice to form an echo, listening to his own echo, there was an inexplicable sense of loneliness.

"What are you still doing on it, hurry up and jump down, I caught the stone you threw down. Ji Xiu's voice came from the black hole below.

Hearing Ji Xiu's voice, Lao Qin finally felt a little relieved, and he scolded: "Bastard, why did you catch that stone, I threw the stone but there was no response, which frightened me." ”

"If you don't just do it, I'll be gone. ”

"Don't! I'll jump, can you catch me. ”

"Nonsense, I can't catch you, why do you want to jump down, just let you hang there all the time. ”

Lao Qin relented, took out a knife to cut off the clue, and his body was pulled by gravity and fell to the black hole below. Lao Qin adjusted his falling posture, lay down face down, and felt out the watch on his left wrist, which was a mountaineering watch with luminescent function, counting the time for one second, two seconds, three seconds, four seconds, and five seconds, and the depth was already more than 100 meters.

Six, seven, eight...... Since I couldn't see what was underneath, there was a growing sense of oppression from underneath, like something was holding down Lao Qin's forehead and trying to squeeze Lao Qin's * out of his skull.

"Ten seconds! Ji Xiu, you bastard-"

Suddenly, Lao Qin felt as if something was hugging him, and the thing changed its trajectory and flew out diagonally along with the thing.

After a plop, the sound of all kinds of sand and gravel rolling down, Lao Qin was very happy in his heart, this feeling of landing safely proved that he was saved. Lao Qin stretched out his hand and patted the thing, and said, "Ji Xiuda, you are so powerful, the fall time is more than ten seconds, the height is already more than five hundred meters, that gravitational acceleration, you can catch me." ”

"Gege...... Gegege...... Gegegege......"

What is this sound, why is the touch of the hand so soft, like the skin of a Shar Pei. Lao Qin wanted to pick up the flashlight on his waist, maybe he was too big, and before he could pick up the flashlight, he was knocked down by something, and the thing pressed his shoulder, and the feeling coming from his shoulder was not like being caught by a human hand.

What cold liquid dripped onto Lao Qin's neck, could it be that his weak neck was targeted by something, and that was okay. The flashlight was pressed under his body and he couldn't even see the light, but fortunately there was a shovel on his waist, but unfortunately it was too dark to see anything, so he smashed it up with a shovel.

I can't think about it anymore, those cold liquids are constantly dripping on my neck, and I can smell a strong fishy smell, this must be saliva, although I can't see it, but I can imagine that there may be a big mouth of blood above my head, and its saliva is dripping on my neck.

Hit it in the mouth, and if you don't, you might be bitten on the neck. Lao Qin fought back, supporting the other party with his feet, and the shovel in his hand kept holding the chisel. This feeling, the shovel has the touch of the flesh, there must be some creature lying on its body drooling, it must be chiseled to death.

"It's all dead, why are you still digging it. This was Ji Xiu's voice, and a light lit up in the darkness, which was the light emitted by the gem in Ji Xiu's hand.

At this time, Lao Qin saw clearly the monster lying on his body, almost a person tall, hairless, eyes as small as a mouse, forehead extremely low, mouth can be stuffed into two heads, with wings connected to the hands and back, wings like bat wings, and feet as small as a baby's feet.

"Oh my God, what a monster. Lao Qin hurriedly pushed it away, his body was full of monster blood, and the fishy smell he smelled before was the bloody smell of this monster, not the fishy smell of saliva.

"Hahahaha, is it fun to ask you to scold me. Ji Xiu pointed at Lao Qin at the camera and smiled.

Lao Qin suddenly realized something, quickly took out the tablet from his backpack and opened it, and when he saw the barrage in the live broadcast room, he understood that this was Ji Xiu's trick.
