After all the efforts of the two of them climbed the thirty-meter-high transmission line tower.

This is an iron monster, standing in the dark night, it is like a steel needle stuck on the earth, making a low "woo, woo" sound under the action of the mountain wind. The higher you climb, the more obvious this sound is. Standing on the steel frame, you can clearly feel that you are one step closer to the sky.

The prince's legs and feet were inconvenient, and there seemed to be fractures. He now relied on the strength of his arms to support him to climb upwards. Gu Zheng followed behind him with the parachute bag on his back. The prince was panting and asked while climbing, "Why don't you jump down directly on this cliff?"

"We have two people. The traction power of this parachute is not enough, which is no different from jumping into a cliff. Moreover, the height of the cliff is not enough. Even if it is enough, the turbulence on the cliff will slap us to death on the cliff like a fly."

"But if we slide like this, have you considered the risks?"

"Yes, yes! I've calculated it." Gu Zheng stopped. They had touched the lowest transmission line. Gu Zheng put two safety belts wrapped in iron chains on it and said, "The lowest point of the 750 kV transmission line is about fifteen meters away from the ground. If there are woods below, the height will be higher. The speed at which we reach the lowest point is about 25 meters per second. Inertia will throw us out and stay in the air for about four seconds. During our stagnation process, the parachute will give us a longitudinal pulling force to reduce our landing speed..."

"Is it like a fighter pilot 0 height 0 angle lateral ejection?"

"Yes! It's like a catapult." Gu Zheng took a deep breath. He heard the barking of dogs approaching them. More than two hundred meters away, a group of people were looking for a way in the woods. They were flashlights, and the sound of wind even tilting the branches and stepping on fallen leaves came. The situation was very urgent.

The prince grabbed the safety rope and turned around, feeling a little nervous, "But the pilot's lateral ejection speed is much higher than ours, but even so, many people died of life."

"No, man!" Gu Zheng said: "Do you want to land intact? It doesn't exist! Instead of worrying about this, you might as well pray that after we are thrown out by inertia, we can fall into a river like a helicopter crash. But I think you should be ready to brake on the ground with your face after landing."

The prince standing in front was stunned for a moment, then turned around and faced Gu Zheng: "Okay, you won, but I would rather throw my back into two pieces than brake with my face."

"Whatever you want!" Gu Zheng tied the third safety rope between him and the prince's waist, tried it, and after confirming that the lanyard was firm, he said, "Are you okay?"

The prince took a few deep breaths, "You'd better guarantee that we can land safely."

"What a waste! Hold it firmly!" Gu Zheng pushed the prince, and the safety rope slid on the transmission line with a "squeak". The prince opened his mouth and wanted to say something, but he felt that the bottom of his feet was empty. Then the safety rope at his waist tightened, and Gu Zheng, one meter away opposite, also slid down.

The prince was so panicked that he turned his back to the bottom of the cliff, unable to see what was going on. The fear in his heart was ignited. He opened his mouth and wanted to shout, but he couldn't shout anything at all. He just threw a mouthful of saliva, which was all spilled on Gu Zheng's face.

The two held the safety rope and slid all the way to the bottom of the cliff on the wire. Although the friction and sliding force was not as good as free fall, the speed was getting faster and faster due to the drop. The whistling wind sounded past Gu Zheng's ears, and the safety helmet on his head was pulled hard by the wind, trembling and feeling like it was about to fly out at all times. Gu Zheng used speed to feel their position. Sliding down from the cliff was a process of inclined acceleration, but this speed would not get faster and faster. Due to the reasons of thermal expansion and contraction, the transmission line would have a arc between the two towers. After they passed through the lowest point of this arc, there would be a significant deceleration process and provide an upward force. But even so, they could not reduce much speed.

The prince said: "Why don't we slide all the way to the tower opposite?"

Gu Zheng explained: "Because you have to bear a load of about one and a half G during the sudden deceleration at the lowest point, and you can't grasp the safety rope at all. Even if you can catch it, the speed at which we reach the transmission line tower below can reach fifteen meters per second. Unless you want to kill the pile of iron lumps with your head. Otherwise, listen to me and let you go."

Even wearing thermal isolation gloves, Gu Zheng clearly felt the heat coming from the safety rope. They were almost approaching the lowest point, and their arms were very difficult, and the prince couldn't hold on. But if they let go at this time, they would only accelerate down at a speed of more than 20 meters per second, and they would die hard.

The prince grinned, "Have you arrived? I can't stand it!"

"Stand!" Gu Zheng was counting silently in his heart. The process of these dozens of seconds was really too exciting, and it felt like a little as a year. The transmission line was pulled by the weight of the two people and deformed. The lowest point was much faster than Gu Zheng had imagined. At that moment, the prince exclaimed. Gu Zheng didn't have time to remind him to let go, but his hands had already left the safety rope. The huge inertia threw him out to the sky. The rope tied around his waist also pulled Gu Zheng together. The two almost flew out one by one, drew a parabola. Gu Zheng silently counted two numbers in the air, and then suddenly pulled a parachute.

Due to the flight altitude, the parachute used by helicopters is to open the parachute at a low opening. The parachute is short and can be fully expanded in one to one or five seconds. The parachute cannot guarantee the safety of the two people. It can only give a reaction force to land. The height cannot be too high, otherwise it is not much different from a useless parachute. So what we need to use is the power of the moment when it opens the parachute. The ideal state is that the umbrella is fully opened and provides the pulling force at that moment, they can land in the next second.

But Gu Zheng stuck to the time and height of opening the umbrella, and the prince was flying in front. His entire back was facing the sky, and then he fell down rapidly. He could not see anything around him, and he could only feel that he was about to fall to the ground. He could even hear the gravel on the ground holding his head in his eyes, ready to smash his fat body.

This is actually the same as waiting for death.

But suddenly, a powerful force came from the safety rope, pulling his body, and straightened his back posture in an instant while falling rapidly. Before his legs could react, they felt that they had already hit the ground, but the strength of his body forward did not disappear. His legs quickly retreated on a rough pebbles ground. Immediately afterwards, the reaction force provided by the parachute suddenly decreased, and his retreating speed was getting faster and faster, and he could not control his body. When Gu Zheng gave him a bear hug, the two of them hugged each other and rolled on the ground, turning over countless fights, and finally stopped...
