After a night's journey, they finally came to the place where they entered the cemetery.

Everyone was exhausted, they leaned Yang Jing against the tombstone, she squinted slightly, without a trace of strength, Haichuan touched her hand, extremely cold.

"Don't worry, we'll be able to get out soon. Professor Qiu grabbed her hand and comforted.

"Uh-huh......" she smiled reluctantly.

Shang Bin looked around, and now the quicksand was not as dense as it was at the beginning, and the middle between the graveyard and the opposite side was like a quicksand waterfall, about more than three meters apart.

"It's very thin sand now, how can we get down?"

Facing Shang Bin's question, Haichuan took out the rope pinned to his waist: "Do you still have a rope on you?"

"Little friend, so you're going to use this?" Gu Kun looked at him with a funny expression, and took out the safety rope, lifter, and half-body safety belt climbing equipment from his bag.

"Don't you have it, this one is for testing the depth below. Haichuan said embarrassedly, in fact, he had observed them when he came at the beginning, and he had seen the items in their bags early on, since he had come to assist Professor Qiu, it was impossible that he had not brought any equipment.

Gu Kun looked at Haichuan curiously, did he know that they had life-saving ropes, and he asked on purpose? As a soldier, he himself has a high degree of acuity, this young man seems to have thought about everything he encounters since he came in, and what surprised him the most was that Haichuan had a calmness that did not match his age, as a soldier, he had experienced life and death, and he would inevitably be confused when facing the dilemma of death.

"Fatty, bring you the empty bottle. Haichuan stretched out his hand.

The fat man looked puzzled: "Why do you want an empty water bottle, maybe I can fill it with water underneath." ”

Although he said so, he still reached out to Haichuan.

Haichuan took it and filled the bottle with sand, then tied it with a rope and threw it into the quicksand. The rope kept falling, and the expression on his face changed slightly, because the rope he brought was 50 meters, and now it was almost more than 30 meters, if it was a tomb palace below, it shouldn't be so deep.

"it, what the hell is hidden down there, it's so deep, it shouldn't be hell. The fat man shuddered as he spoke, remembering the previous rumors and what the herding uncle said, could it be that the so-called gate of hell is below?

"Dead fatty, don't be alarmist!" he kicked the fat man, and everyone was already in a very low mood now, but the last hope could not be dashed.

The fat man knew that he had said the wrong thing, so he quickly covered his mouth, but he couldn't help but say something in his mouth: "Alas...... It's better to throw the rope over to the other side and leave this hellish place. ”

"There's no going back. Even if we crossed the quicksand and passed to the opposite side, we would not have been able to get out alive on foot without a car. Shang Bin didn't know when he came to the fat man's side and scared the fat man.

Before the rope was finished, Haichuan connected the lifesaving rope brought by Shang Bin together, and after a while, it was obvious that the bottle full of sand was not sinking.

"Stop, stop!" the fat man pointed to the rope.

"It's about 70 meters deep down there. Haichuan looked at Shang Bin.

"There are two sets of safety belts for you here, and Professor Qiu and Yang Jing will hand them over to us. He said and looked at Yang Jing and Professor Qiu behind him, for them, rock climbing is a daily training project, even if the mountain is very sloping, they can go down with their bare hands, at most it is more dangerous, not to mention that they have more hooks and locks tied to the rope, so that the safety is improved a lot.

He pushed a few tombstones next to him, and when he saw that they were very strong, he tied the hook and rope to the tombstones.

"Who's going down?" Gu Kun asked.

"I'll do it. Haichuan took the safety belt and the lifter.

"Be careful. Fang Jingxuan whispered, looking at Haichuan worriedly, wanting to help but having no choice.

"One of you goes down with him, this fat man will carry another one, and I don't have the strength to carry one. Gu Kun threw the rope at them.

"Gu Kun!" Shang Bin looked at Gu Kun sharply, and knew that he must be angry when he heard Shang Bin call his name directly.

"Otherwise, if we don't have a safe belt, we will carry it, now is not the time to pretend to be great, and we will be thrown to death, or what beast is waiting for us to enter its mouth?"

Fang Jingxuan grabbed in front of the fat man and jumped on Hai Chuan's back.

"Can you do it?" Seeing that he was strongly supported, the whole person couldn't stand steadily, and he couldn't help but feel distressed.

"Fatty, tie us from the waist with a rope. ”

"Oh......" The fat man reacted with the stunned look he had just made.

"Hold on to me, don't be afraid. ”

Fang Jingxuan nodded, she covered the two of them with her clothes to block the sand, Haichuan fell, the sand fell on her body and made her body sink a lot, and there was no line of sight, it was easy to look when the probe went out, and the nose went into the sand.

After descending some distance, he kicked the side, and sure enough, as he expected, this was a wall, no! It should be a mountain wall to be exact, and it could not be hollowed out if he wanted to build a cemetery on it, and as he tested the depth, he clearly felt that the bottle full of sand was falling as if it had hit a cliff.

The further down he went, the sand gradually decreased, Fang Jingxuan lifted his clothes, and it was pitch black at a glance, but he clearly felt the sound of sand falling from the side.

"Fang Jingxuan!"

Faced with Haichuan's sudden call by her name, she was shocked.

"What did you hear?" Haichuan asked in a low voice, as if she was afraid of disturbing something, which made her nervous, and subconsciously grabbed his shoulders tighter.

She listened carefully, hearing nothing but echoes.

"It's the sound of the wind," Haichuan's voice looked a little excited, "There is the sound of the wind in the abyss of such a deep canyon, and I guess it should be a dark river below." ”

If it is a dark river, it proves that this dark river is flowing, and it will produce wind, so it is calculated, that is to say, this one may find an outlet along this dark river, and the most important thing is that if the water in the dark river is drinkable, then they can last a few more days.

Haichuan accelerated the descent, about 40 meters down, faintly heard the sound of falling sand afraid of hitting the water, it stands to reason that the sand fell for so long, isn't the designer worried about the sand piling up to the height of the ground?

"Help me take my phone out of my pocket and turn on the flashlight. ”

Fang Jingxuan reached in and found it: "Why is your phone so small?"

"Ahem...... In the pocket on the back of the pants. ”

"Oh. Fang Jingxuan replied suspiciously, remembering something, "What was just in your pocket?"

"That ......" Haichuan looked embarrassed and didn't know how to explain it.

Fang Jingxuan seemed to suddenly understand something, and was quiet for a while, if she could see her face at this moment, her whole face would be blushing.

She turned on the flashlight, and a faint light in the darkness made people feel a little more secure, and when she shone down, she was surprised to find that there was a reflection of water light as Haichuan said.

When they descended very close to the water, they realized that it was really a dark river with a very fast current.

But they don't have a foothold, even if there is an outlet along the dark river, is it possible for them to swim out?

I saw Haichuan unhurriedly untie something from his waist and open it to the inflatable bed they had used before.

"You still have this thing with you?" Even Fang Jingxuan wondered, walking in the desert not only brought trouble to his body and increased the burden of walking, but also this thing seemed to be useless. He suddenly remembered that he hadn't seen him take it out and sleep again, except for the first time he took it out for camping!

"After watching so many martial arts TVs, the male and female protagonists fell from the abyss and didn't die, and there are usually lakes or pools below. Haichuan joked, making people feel that he is still the bad teacher who likes to go to the night club.

Fang Jingxuan shone a flashlight on his face, always feeling that he was hiding something from her.

"Okay, I'll be honest with you, I was already guessing a problem halfway through the graveyard,"

"What's the problem?" Fang Jingxuan asked curiously.

"We all think that we have unintentionally touched the dangerous switch, and we are desperately going inside, trying to find an exit, but have you ever thought that this is the opposite is the exit," he paused, as if what he was about to say was the conclusion that he had been thinking about for a long time, "this is not just an exit, but it may also be a place where the secret of the 'frozen soil' is buried!"

In fact, he never told them that since he had come here, he had not suffered a single physical illness, but on the contrary, the closer he got here, there was a strange feeling, this feeling was like a person walking in a long dark abyss in a dream, and a voice in the dark called to him, telling him to walk in the direction of the sound.
