"Is this a ventilation duct? I don't know very well. ”

After hugging the round pipe, Bi Fang's rare Nahan got up.

Because this pipe is not the same as the usual one, it is not smooth, but has a lot of small pipes raised, it is a fairly cheap starting point, it is very suitable for climbing, and in the selected route, this ventilation pipe is the best to climb.

"It's a bit like climbing a tree, I explained it a long time ago, you have to check every landing place before you move, this time you have to pay attention to the grease and dirt everywhere, it's like this in the factory, you can hardly find the forest that is not shiny, and you have to be extra careful when reaching for them."

Bi Fang stretched out his hand and showed the black oil stain in his palm to the audience, it was very greasy, and such an oil stain could wipe a large piece with a single touch.

Fortunately, the presence of dust makes the situation not so bad, and with dust, even if it is slippery, the degree is limited.

"It is important to keep in mind the law of three points, which is the most critical of all the laws of climbing, that three of the limbs are to be firmly attached to the attachment and to be distributed in three different positions to form three fulcrums.

If you put two feet in one place, you can only see it as a fulcrum. ”

As a veteran, Bi Fang is already very proficient in climbing with a simple ventilation pipe, and the audience can only see his smooth climbing figure, if it is not a live broadcast, even wonder if he has rehearsed in place many times, otherwise how can he be so proficient?

[I always feel that Lao Fang's level is getting more and more powerful, and the first time I watched his live broadcast, it wasn't so smooth, although it was also very powerful, but I didn't feel as powerful as it is now]

[Awesome, but not completely]

[I feel stronger than the coach in the place where I learned rock climbing, I am ruthless in my hands, my strength is still strong, and I am stable! ] 】

There are knowledgeable people in the live broadcast room, and you can see at a glance that Bi Fang's climbing action seems simple, but it can't be done without thousands of tempers.

It's weird.

Looking at Bi Fang's young face, many people sighed secretly in their hearts.

It turns out that there are really geniuses in the world.

Soon, Bi Bian came to the end of the ventilation duct, and on one side was a beam made of steel, strong and cold.

"It's a hard climb and it's dirty, but I've climbed the first floor, and I'm getting closer to my goal."

Bi Fang reached out and grabbed the I-beam, the sleeves of his shirt fell, showing the smooth muscular lines of his forearms, and his legs clamped tightly to the ventilation pipe, still not daring to relax.

After stretching his arms and pulling his upper body to the crossbar, Bi Fang gradually loosened the ventilation pipe, and finally slowly stood on the I-shaped steel beam.

The drone flew directly in front of Bi Fang and filmed meticulously.

Looking down from above, the height of more than fifteen meters made all the audience breathe, as if stepping on a tightrope, making everyone sweat for Bi Fang.

Especially when the drone camera captured him lying on the sole of the I-beam, this tension was once again ruthlessly exacerbated.

It's the familiar Fangshen taste again!

Bi Fang stood on the beam, balanced his body, and pointed to the window road not far away.

"You see, there's a broken window on the top, and I guess that's where the pigeons get in and out, and there's a good chance that the pigeons are nesting there, so we'll go and see, but we'd better make some preparations."

The words fell.

Bi Fang untied a thick hemp rope from his waist, which he found underneath, wrapped one end of the hemp rope around his waist, and then passed through the I-beam and tied the knot.

"Because we have to walk over, in order to prevent accidents, we still have to do some protective measures, here I teach you a knot, the figure eight knot, because this knot is knotted like the shape of '8' and gets its name.

The figure-of-eight knot is mostly used in occasions with strong slip resistance. For example, rappelling, rock climbing, etc. will be used, we first cross the end of the rope, the end of the rope around the main rope through the rope loop, wrap two circles and then tighten to complete. The way to play is simple, and after the knot is quite strong, it is a classic knot knot. ”

The knot is not difficult to learn, and it almost does not automatically unfold after holding the end of the rope, which is a very convenient knot.

As he spoke, Bi Fang's fingers flew, and a knot similar to the number 8 was tied.

Standing on the beam, Bi Fang stretched out his hand and pulled it, it was very firm, and after making sure that it was safe, he reached out his right foot and moved towards the other side of the factory little by little.

[Nima, it's a little exciting! 】

[I can't afford to provoke, I really can't afford to provoke, I don't agree with a word to play exciting! ] 】

[There is a kind of fear in the world, called being afraid of looking at it]

Ignoring the barrage, Bi Fang calmed down, breathed steadily, and didn't seem to be moved by the environment.

This is actually the psychological quality necessary to do any risky behavior, the heart is stable, the heart is not sinking, and the possibility of accidents is greater.

So you can't be afraid, you have to move forward with indomitable courage.

What's more, the I-beam is not a steel cable, and it is much smoother than a steel cable, as long as the center of gravity of the body is as controllable as possible.

Dragging the hemp rope, Bi Fang soon came to the opposite side of the I-beam.

The road is much easier to walk here, with narrow corridors and fences.

Untying the knot, Bi Fang rolled over and fell into the fence, and the audience breathed a sigh of relief, but before they could recover from it, they heard Bi Fang's voice again.

"We can try to go up from here."

Bi Fang stepped on the fence and climbed up the pipe again, this time, his height had reached nearly thirty meters!

Then I stepped on a rail again!

Weird!

No one can be calm now, because this is different from the previous rails, from the side, like a gate, long and flat, it is impossible to tie a knot at all!

Even the width is narrower than the previous I-beam!

But in this situation, Bi Fang only took two deep breaths and slowly poked out his right foot, only this time, he did not immediately follow his left foot.

He looked ahead, his expression solemn, and even a little cold, he needed to find a suitable moment to cut in.

Walking at this height can only be done in one go, and must not be stopped.

After waiting for five minutes, the sailors saw Bi Fang's toes leave the roof beam and completely come to the rails!

After that, it was a mechanical advance, calm and a little scary.

The sailors were so shocked that they were a little numb, they were okay before, after all, there was a "safety rope", but now they can't help but be afraid of this situation.

It's too dangerous!

[Solution, how to maintain balance?] 】

[Fuck, it's really scary, it's a fucking live broadcast! ] Outrageous]

[I'm already taking care of my grandfather in the hospital]

[Good guy, how many times have you been in the hospital? Coaxing the party and filial piety]

[Every time I watch Fang Shen's live broadcast, there is one less bed in the hospital! ] 】

[There is no live broadcast, there are beds! ] 】

Climbing to the top of this factory is like climbing the high crown of the rainforest, strength, technology are indispensable, and you also need to be clear in the high place.

Bi Fang kept his balance on the edge at all times, his nerves were highly tense, all his senses were highly concentrated, and even his sense of smell became more sensitive.

The stench of rotting pigeons, the stench of bird droppings......

The sun was setting outside the house, and the slanting sun was shining on him through the window, like a god.
