Rob came to the edge of the rock wall, turned on his flashlight and looked down. The distance of more than ten meters made him take half a step back in shock.

How the hell does this happen?

"It's not a big problem. I brought a rappel rope." Bi Fang picked up the long rope on the ground. Under the light, the long rope was dazzlingly white. Bi Fang untied the tightening sleeve and explained

He said, "Despite the small size of this rope, the actual length is fifty meters."

what? fifty meters?

The audience looked at this white rope that can be held with one hand. Is it fifty meters long?

【It should be, this rope looks so thin.】

[Is this rope too thin? It’s so thin that it can still hang someone. Is it nylon? 】

"It's not nylon. Dyneema fiber, also known as Dyneema fiber, is technically classified as ultra-high molecular weight polyethylene fiber. It is the strongest substance that humans can currently synthesize. The fiber thickness of this thing is one thousandth inches, and has a significant strength-to-weight ratio, which also makes it the strongest fiber in the world."

Bi Fang tied a new knot, then searched for it on the platform, and successfully found a stone pillar, which saved him from having to nail it.

"Dyneema fiber has ultra-long molecular chains, which allows the load to be transmitted to the main chain more effectively. This physical property allows Dyneema fiber to have higher tensile strength compared with other fibers of the same mass, and the same tensile strength The higher the strength, the lighter the weight. Under the same mass, the tensile force of Dyneema fiber is 15 times that of steel. It is also anti-cut, anti-shearing, and processing even requires the use of laser. It can be regarded as a length of steel cable. It is the first choice for outdoor sports. .”

Bi Fang put the knot on the stone pillar and stepped on it hard. It was very strong.

"Will everything go down?"

Everyone, including Zelong Rob, nodded. They were all climbers, and it would be embarrassing to tell anyone that they didn't know how to descend.

After confirming that the stone pillar was strong, Bi Fang wrapped the rope around his waist, handed one end to Rob and others, and then came to the edge of the stone wall: "Even if you are sure that the stone pillar is strong, don't descend rashly. It is best to use double or even triple insurance. Then come to the edge, tilt back a little, apply gravity, and wait until it is fully tilted and still firm, then you can start to slide down. At this time, it is best to wear gloves, otherwise it will be easily scratched. "

The tilt test was completed, and Bi Fang, who had confirmed safety, began to descend little by little. Descending was much easier than rock climbing. He could descend from a distance of more than ten meters in a few breaths.

Then came Zelong, Rob, and the Sherpa porters.

The rescue was completely over when everyone came down.

"Damn, this is too dangerous, brother, you are such a cruel person." Yao Jun watched Bi Fang put away the rope, with lingering fear. On the live broadcast, he was like sliding to the edge of the cliff, unable to make any movements, and still a little bit The scene of sliding down is really disappointing.

Zelong was a little embarrassed by the praise and bowed again to apologize: "I have caused you trouble."

Bi Fang shook his head: "It's okay. We are all compatriots. It's normal to help when we encounter difficulties. But next time it's best not to leave the team and act alone. If I hadn't heard, you would have been completely finished at that time, you know?"

"Even if I die, I won't be able to leave the team. I will stay with the guide even if I die!"

Bi Fang smiled and then returned to the camp with Zelong.

After Zelong expressed his thanks again, he left the team and went to find his own tent.

Returning to the tent, Bi Fang immediately approached the stove to warm his hands, while Wang Yongbo and others began to make dinner. They didn't even know what happened.

Bi Fang picked up a bowl of unknown food and put it in his mouth. The sticky texture almost made him spit it out.

"Holy shit, what is this?"

“Egg noodles.”

Wang Yongbo handed over the chopsticks with an expressionless expression. At their altitude, the boiling water was only over 80 degrees, so it couldn't cook anything at all.
