Ning Fei opened his parachute in mid-air and landed precisely on the spot where his tool bag had landed.
He put away his parachute, put his tool bag on his back, and walked towards the entrance of the cave.
The entrance to Kuluboyarra’s cave was not far in front of him.
The Dark Cave looked like a long crack.
But even in such a place, it could reach a depth of more than two thousand meters.
This was the deepest cave in the world, and it was also the only cave in the world with a depth of more than two thousand meters.
Just looking at the entrance of the cave made people feel weak.
Ning Fei fixed the rope at the entrance of the cave. This was the key to his exploration, and he could not make any mistakes.
Then, he took out the rope from his tool bag and started to lower it.
The rope was very long. After the heavy object fell into the cave, it kept going down.
“This rope is 2,500 meters long. The quality is made of new materials. It’s flexible, lightweight, and very strong.”
