Ye Han originally thought that the ice cave went straight up and down, and it would not take long for the drone to penetrate the ice. But after a while, he discovered that something was wrong: there was a thick layer of flowers on the walls of the ice cave, and the icicles fell deeper and deeper.
The hole became narrower and narrower, and the icicles hit the wall of the hole and immediately wiped away a cloud of frost.
Isn't this a special situation? It's only 20 or 30 kilometers away and the traffic is like this. What will it look like if it goes deeper?
As expected by Ye Han, the icicles continued to fall for a certain distance and began to hit the cave wall frequently. After a while, the holes between the ice and frost were about the same size as the icicles. The icicles kept rubbing against the frost, and their speed suddenly slowed down.
Within ten seconds, it was stuck by the frost, unable to move up or down.
Ye Han was extremely annoyed, but there was nothing he could do.
It was impossible to penetrate the ice directly, so he could only place his hope on the No. 1 hole.
At this time, Cave No. 1 was still releasing high-strength fibers in an orderly manner, and the drone had descended about ten kilometers below the cave, much slower than Cave No. 2.
Ye Han stared at the monotonous picture returned by the drone and began to wonder how to successfully send the drone under the ice... The simplest way is to block the ice hole first and then penetrate the ice layer below, but
How can I block the ice cave?
The thoughts in his mind went around for a few times, and he suddenly felt that it was necessary to test a few more times. There was only ice cave No. 1 left. If something went wrong, he would have to dig another hole. It was too time-consuming, so he ordered He Lu to continue digging.
holes, and there are several in a dozen.
In addition to preparing a few more ice caves, Ye Han also did not forget to report his ideas to the flagship, asking the flagship to help think of a way. As long as the ice caves can be blocked, the rest will be easy to handle.
Ye Han didn't have much hope at first, but Luo Qi quickly received a reply from the flagship and sent Ye Han a schematic diagram on how to block the ice cave.
After Ye Han got this extremely simple sketch, he was startled at first, and then burst into ecstasy: "Luo Qi, send this picture to a group and ask them to follow it. If they need anything, report it immediately; inform the second group to report to the first group.
The groups move closer together and are under unified command by the group leader!"
Soon after, one group received the order and sketch, and the group leader immediately waved and shouted: "Stop, everyone stop!"
The soldier operating the winch stopped instinctively, and the flying winch stopped quickly. Everyone looked at the team leader in surprise, wondering what the stop at this time meant.
The team leader sent the sketch to the soldiers: "I need a volunteer!"
"Me!" Several soldiers stood up together.
The team leader pointed at one of the soldiers: "Shen Bingyan, it's you, the others will take action immediately, quickly, quickly, quickly!"
The soldiers immediately moved, hung the spare winch on the rack, tied another high-strength fiber to Shen Bingyan's body, pulled it hard a few times, and then extended their thumbs after confirming that there was no problem: "Okay!"
After hearing this, Shen Bingyan took a deep breath, bent her legs, and her whole body was immediately lifted up by the high-strength fiber, swinging from the outside of the ice cave to directly above the ice cave like a swing.
The heavy power armor fell and the simple hanger sank slightly. It floated up and down a few times before it stabilized again.
The team leader pressed down gently with his palm: "Let it go! Let it go! Let it go..."
Under his command, the soldiers slowly released high-strength fibers, and Shen Bingyan slowly sank into the ice cave, and soon disappeared.
The team leader asked worriedly: "Shen Bingyan, how are you?"
A heavy gasp came from the radio: "I'm fine, I can go faster!"
"Received, if you feel something is wrong, tell me immediately!" the team leader instructed.
"Don't worry, team leader, I'm fine!"
"Be careful!" The team leader made a speeding up gesture to the soldiers, and the hoist was lowered a little faster.
At this time, the whole second group arrived and saw that the first group was busy. The leader of the second group immediately took his soldiers aside and waited for the command of the first group leader.
The first team leader ignored them for the time being. He nodded to the second team leader as a greeting and concentrated on directing the operation.
In this way, it took one group more than ten minutes to put Shen Bingyan seven kilometers below the cave. The winch slowly slowed down, and Shen Bingyan finally stopped at 7.4 kilometers below the cave.
The team leader breathed a sigh of relief: "Shen Bingyan, are you ready?"
Shen Bingyan reached up to the top of his head with one hand and grabbed it several times until he caught the high-strength fiber before letting out a sigh of relief: "Okay!"
"Then let's get started!"
"good!"
The team leader made a gesture, and several soldiers gently pushed the hanger, and the hoist immediately moved a little to the left.
Shen Bingyan's back in the cave hit the cave wall, and he immediately shouted: "Reverse, reverse..."
However, it was already too late. Even though it was only a slight push from the top, it shook greatly when it reached the bottom, and its back hit the cave wall directly.
It didn't hurt, but the impact angle was inappropriate. Shen Bingyan seemed to have been whipped by someone and was hanging down in a circle involuntarily.
The team leader quickly changed his gesture, and the soldiers immediately pushed the hanger in the opposite direction.
Everyone thought that this time it was definitely stable, but they didn't expect that Shen Bingyan, who was hanging below, was so dizzy that his back hit the cave wall again. He was so anxious that he shouted: "It's reversed, it's reversed again!"
"
The team leader was immediately furious: "The left side is countered, the right side is countered, which end is not counterattacked?"
Shen Bingyan was helpless: "Forget it, just go anywhere, I'll stabilize it first!"
The team leader signaled again, and the soldiers immediately pushed the hanger aside. The high-strength fiber gradually stuck to the edge of the hole. Shen Bingyan, who was hanging below, also leaned against the cave wall and finally stopped turning.
He took a breath first, turned around and faced the cave wall, held his feet on the ice, took out his laser gun and cut on the ice. After a few moments, he cut off a piece of ice from the cave wall, threw it away and continued cutting.
After two clicks, I found a space large enough to fit in.
After struggling to move into the two-meter-square area, Shen Bingyan first pulled out the fixing cable from the armor, nailed the cable head into the ice, and after fixing himself, he took off the high-strength fiber on his body and fixed it in the hole as well.
On the wall: "Team leader, it's done!"
The team leader signaled again, and the soldiers immediately locked the hoist. One soldier held the high-strength fiber and lightly jumped into the ice cave.
Shen Bingyan continued to expand the space in the ice cave to prepare a place for his comrades.
In this way, the soldiers descended into the cave one after another, and the space seven and four kilometers below the cave became larger and larger. The first step was to dig horizontally, and dug the original five-meter-diameter ice cave into a diameter of ten meters.
Double the diameter of the ice cave!
Moreover, the soldiers did not dig randomly. In addition to ensuring that the diameter reached ten meters, the cave walls also had to be smoothed as much as possible, especially the upper section at the diameter change. Not only the angle had to be vertical, but the section also had to be flat, which cost the soldiers a lot of time.
Only strength is enough.
Fortunately, the most difficult part is only this section. After repairing the variable diameter, the rest will be much easier.
The soldiers continued to dig downward, gradually extending the diameter of ten meters downward. Instead of just repairing it to ten to eight meters, they started directly from 100 meters.
