The length of the cliff is about 20 meters, and Uncle Dog has to throw the barb over.

Before saying this, Lin Changsheng had already observed the opposite side, and there were two boulders there, which could be used as a point of strength.

Uncle Dog only prepared three things before coming, one is the black donkey's hooves, the second is the barb, and the third is the black line.

There are many kinds of black lines, some are long and some are short, and the short ones are only seven or eight meters, which are used to bind zongzi.

Length, up to thirty or forty meters, is just to cope with the current situation.

"Is it okay to be so far away?"

Qiu Yihan was a little worried, after all, Uncle Dog's figure was too thin.

Uncle Dog didn't say anything, he replaced it with a long line, turned the barb with one hand to borrow the force, and after about a dozen turns, he suddenly threw it forward.

A sound of breaking through the air was heard, and the barb successfully landed on the opposite side, but it did not wrap around the stone, and Uncle Dog could only pull it back again.

Although it didn't succeed, being able to throw it to the other side was enough to impress Qiu Yihan.

"The wind on the cliff is too strong, and you have to work harder."

For Uncle Dog, the first throw is just a temptation.

He continued to borrow, this time a full dozen turns, and then threw the barb out.

This time the force is obviously stronger than last time, even with strong wind resistance, the barb still flew over the boulder, Uncle Dog immediately controlled the black line, and then the barb rotated, with the black line wrapped around the boulder, and it was wrapped three times.

Uncle Dog pulled hard, glanced behind him, and tied the other end of the black line to the naturally formed stone pillar.

Bolair was a little worried, and said, "This line is so thin, can it bear people?" ”

The black line was also half the thickness of his little finger, and he was a little uneasy.

"I'm afraid I won't be able to bear it, so don't go over."

Uncle Dog snorted, immediately looked at Lin Changsheng, and said, "It's okay." ”

Lin Changsheng nodded, walked to the cliff, grabbed the black line, and said, "I'll go first and show you." ”

The demonstration here is mainly for Ye Lin and Chen Xue, and Uncle Dog and Qiu Yihan are familiar with this.

After speaking, he took out a pair of tactical gloves from his equipment bag and put them on, the black lines are relatively thin, and it is easy to strangle the palm of his hand without protective gear.

After everything was ready, Lin Changsheng jumped forward, grabbed the black line and hung forward towards the opposite side.

The 'whirring' yin wind continued, Lin Changsheng's clothes were blown up, he walked forward alternately with his left and right hands, and it didn't take long for him to reach the opposite side.

After arriving, he didn't rush to let Uncle Dog and them come over, but tightened the black line wrapped around the boulder, and then made an 'ok' gesture to Uncle Dog and them.

Chen Xue and Ye Lin have both trained in military skills such as rock climbing, and with Lin Changsheng's demonstration, they can understand it at a glance.

Ye Lin tied the fool to himself, and the fool probably also realized that it was dangerous, so he didn't make a fuss at all, and hugged Ye Lin's body tightly.

After about half an hour, everyone came.

After coming over, Chen Xue frowned and said, "What about the black unicorn?" ”

"Don't worry, it's easier than us."

Lin Changsheng smiled, blew a whistle, and shouted loudly: "Black Qilin, you can come over!" ”

As soon as the words fell, I saw the black unicorn bite off the black thread tied to the natural stone pillar, and then bit the black thread and rolled on the ground a few times, so that the black thread circled around his body several times.

After doing this, the black unicorn jumped off the cliff.

Qiu Yihan and the others' faces changed in unison.

Lin Changsheng grabbed the other end of the black line, and the black unicorn's body collided towards the opposite cliff and rock wall, and with a muffled sound, Ye Lin and the others suddenly felt a pain in their flesh.

But the black unicorn is very strong after devouring the blood corpse, and it is not afraid of the impact of the rock wall at all.

And Lin Changsheng pulled the black line, and the black unicorn couldn't fall, it immediately used its four claws to kick the rock wall to climb up, the speed was extremely fast, like a ghost, almost instantly, it climbed up from the rock wall.

Qiu Yihan's face was shocked, and he said, "Is this still a dog?" ”

Uncle Dog said with a smile: "Strictly speaking, a ghoul dog can no longer be considered a dog, let alone a ghoul dog after devouring a bloody corpse." ”

"Awesome."

Lin Changsheng touched the head of the black unicorn and praised it, and the black unicorn squatted there with his tongue drooping and laughing.

Uncle Dog put away the black line and barb, and Lin Changsheng took out the pen book from the equipment bag, and marked it with a black pen on the painted tomb map, and the line drawn in black represented the cliff.

The passage ahead is a natural cave that gives the feeling of coming to another mausoleum.

Qiu Yihan used the mechanical mouse to explore the path again, and after about ten minutes, he came to a conclusion, saying, "There are no traps and traps in it, but there are many things. ”

Ye Lin asked, "What is it?" ”

Qiu Yihan said truthfully: "The mechanical rat has the smell of bat feces, and there are many poisonous insects in addition, let's put it this way, this cave is natural, similar to the cave outside, but it definitely can't be compared with the blood spicy people we encountered before, as long as we are more careful, there is no big problem." ”

Lin Changsheng asked, "How long is this cave?" ”

Qiu Yihan carefully put the mechanical mouse back into the small bag and said, "The straight-line distance is only four hundred meters, but the curve distance is about two thousand meters. ”

After speaking, Lin Changsheng glanced at the route on the remote control, and drew it on the drawing of the tomb with a red pen.

He came not only for his own curse, but also to explore the way, if he can have a complete map of the tomb, then it will be of great help for future development and protection.

Everyone entered the cave, and soon after leaving, they saw a group of bats hanging on the rock wall, the bats were a group of small bats, and they would not attack people, since this was the case, Lin Changsheng and the others naturally didn't bother to provoke them.

It's very humid, and you can see a few scorpions and centipedes crawling by from time to time, and there are also many poisonous insects that are not known as well.

After walking about seven or eight hundred meters, the crowd stopped.

There were flames floating in front of them, red, blue, and green, and although there were not many of them, they were floating around and looking very infiltrating.

Chen Xue looked at Lin Changsheng and asked, "Is this phosphorus fire?" ”

Since the last time she left Diling, because of the limited time, although she didn't read many books, she also knew about phosphorus fire.

Lin Changsheng nodded.

Phosphorus fires, also known as ghost fires, are usually found in rural areas, more often in dry summer days, but occasionally in cities.

The scientific explanation is that human bones contain phosphorus, and after the corpse decomposes, it will produce phosphine, which has a very low ignition point and can spontaneously combust.

The scientific explanation of ghost fire chasing people is that because the phosphorus fire is very light, if the wind or people pass by to drive the air flow, the phosphorus fire will also float with the air, and even accompany the steps of people, you are slow and it is slow, you are fast and it is fast, when you stop, because there is no force to drive the air, so the air will stop moving, and the ghost fire will naturally stop.

However, the person who said this may not know that the wind will not stop.

Just because you can't feel the wind doesn't flow doesn't mean it doesn't.
