"Xiao Chen, you said that the God King may still be alive," Rou'er was excited,

He nodded and said, "There is such a possibility, but I am not sure, because it is a bottomless cliff, whether Cai Qing is dead or alive, I am not sure yet, but, consciousness tells me that it is very likely that she is not dead,"

"Great, even if there is only a glimmer of hope, it is better than no hope, the cliff you are talking about should be the Poison Dragon Cliff," Rou'er said: "It is indeed a bottomless cliff, no one knows how deep it is, even the strongest eagle cannot fly up from the bottom of the cliff,"

Xiao Chen's face tightened: "No, then how can we go down to find Caiqing, according to what you said, even if you get a rope and throw it down, you have to have many ropes connected together, where to find so many ropes,"

Rou'er also made a difficulty, saying, "You need a lot of rope, and it's really hard to find it in a short time...... I think of a place where there must be enough rope and some other aids,"

Xiao Chen was overjoyed: "What's the place, say it quickly,"

"The palace warehouse, in addition to the various treasures collected by the God King, there are many kinds of strategic materials, and rope is one of them," Rou'er replied.

"So what are you waiting for, take us to the warehouse...... Forget it, just to be on the safe side, you still mark the specific location on the map, tell me how to open the gate, the two of us go in, you stay outside to let the wind out," he said,

Rou'er cautiously asked, "Do you need someone to let the wind out?"

"Of course, this is a very important thing, in case of an accident, you can be out there to deal with us," he said, vowing

"Well, the exact location of the warehouse, on the east side of the palace, the way to open the gate is ......"

A few minutes later, Xiao Chen and Piao Piao stood at the gate of the warehouse, and sure enough, as Rou'er said, these were two metal doors, which were very strong.

He smiled and opened the lock,

Piao Piaoxiu's eyebrows furrowed slightly, and said, "You didn't let Rou'er come over, you have ulterior motives,"

"It's still Piaopiao's wife who understands me," he replied with a smile, "If I am followed by Rou'er, how can I be embarrassed to take something other than the rope, didn't I hear her say, there are all kinds of treasures collected by Cai Qing here, we finally came here, and we won't go back empty-handed,"

"If you take someone else's things, will you be embarrassed when you face Caiqing in the future," she asked again.

He replied with an oath: "Cai Qing is probably dead, then the things here are ownerless, and there will be no chance to meet in the future, why don't you take it,"

"What if she hadn't died,"

"We've worked so hard to find her, and it's always time to pay a little bit,"

"Well, you won,"

As the two ended their conversation, the door lock clicked crisply, and the door automatically opened left and right.

This is a very large warehouse, which stores all kinds of items, weapons, armor, silk, cloth, everything, piled up like a hill, magic crystals, medicinal herbs, pills and other valuable things, stored in one of the corners,

Xiao Chen walked straight to the corner, Piao Piao shook his head helplessly, and followed,

The magic crystal of the 10,000-year-old spirit beast alone has more than a dozen boxes of large and small, and the six-storey pill shelf is made of fine mahogany, and it is full of porcelain bottles containing pills.

All kinds of precious medicinal materials can only be placed anywhere,

He shook his head and said: "It's really a loser, didn't you say that the Emperor's Extreme Realm is very barren, there will be so many valuable things for Mao Caiqing, it must be obtained by exploiting the poor working people,"

Piao Piao was too lazy to listen to his crooked reasoning, picked up the things he liked and put them into the bracelet,

Soon, the corner became empty, and then they began to loot other items, and finally the destination of the trip, the place where the other party roped,

Hundreds of bundles of sausage-thick hemp rope were put away by him, plus dozens of pulleys, and a few parts for assembling iron shelves,

"What are you doing with these things," Piao Piao asked, puzzled,

"Hey, you'll know when the time comes," he said.

Half an hour later, they left the warehouse, and Rou'er was waiting for them to die, thinking that something had happened to them.

Of course, Xiao Chen wouldn't tell her about emptying the warehouse, but casually made up a reason,

Then they came to the Poison Dragon Cliff,

After some production, he fixed a thing similar to a mechanical arm on the edge of the cliff, and more than a dozen pulleys were hung at the front end to form a pulley group composed of static pulleys and movable pulleys.

Piao Piao and Rou'er couldn't understand, he explained: "According to physics, a moving pulley can save half the force, and my pulley group only needs one-sixth of the force to lift heavy objects,"

Piao Piao asked, "What is physics?"

Rou'er asked, "What is a moving pulley?"

Hearing this, his smug energy disappeared, and he muttered, "You don't have to figure out its construction, you just need to know that it's a labor-saving device,"

"You mean to say that after passing through it, a thing that weighs only one-sixth of its strength can be lifted, right?" asked Piao Piao again.

He nodded and said, "yes, that's amazing,"

"But have you calculated the weight of the rope?" she asked, a very pointed question.

He was stunned: "The weight of the rope,"

"That's right," Piao Piao pointed to the rope piled up next to it, and said: "The Poison Dragon Cliff is bottomless, we need to use a long rope to reach the bottom of the cliff, these ropes alone weigh hundreds of pounds, when you pull the rope, not only the weight of three people, but also the weight of the rope, and the resistance caused by the friction between the rope and the pulley, have you calculated these clearly?"

"Uh," the little prince sat on the ground and cried bitterly, "I didn't take that into account, and I can't figure it out, but there's nothing wrong with adding a few more pulleys, you wait a little longer,"

A person who has never been exposed to physics can ask such a question, which caught him off guard.

He added four more movable pulleys to the pulley group, and his heart can basically offset the weight of the rope, as well as the so-called friction.

Next, start putting the rope underneath,

Two ropes were put down at the same time, one was the main rope, connected to a large bamboo basket, Xiao Chen and Piao Piao stood in the bamboo basket, and the other was a safety rope, every 100 meters, he would tie a red ribbon on it, in order to calculate the depth of the cliff,

Soon, the two of them went down to a position that Rou'er's line of sight could not see, 6,300 meters,

The red ribbons decreased one by one, and the time passed minute by second, and when it came down to 10,000 meters, gray fog appeared, and the fog concentration reached the extreme after 500 meters, and then it began to thin out, and completely disappeared after 800 meters.

However, this situation occurs one after another, sometimes it is fog, sometimes it is clouds,

In this way, they passed through layers of obstacles, but they still couldn't see the bottom of the cliff.

Until the three hundred and sixty-first red ribbon was tied, Piao Piao exclaimed: "Chen, I see the ground, there are only a few hundred meters left,"

He lay on the edge of the bamboo basket and looked down and said, "Yes, why can't I see it, the fog down there seems to be very thick, how do you see it?"
