Six Hundred and Seventy-Two Falling

The terrain in the cave is complex, and the soldiers move very carefully to avoid being careless and in danger.

After searching the cave where the exit was located, the team, which found nothing, continued to move deeper into the cave.

Liu Bin came close to Ye Han and asked in a low voice: "Chief of Staff, why can't you see a single wolf in this place? If this place is really a wolf's winter nest, you have to arrange a few insects to watch the door, right? It's so big. Isn’t it too careless to drive without anyone interested?”

"I'm not sure whether it's an insect nest or not. Let's take a look first and then decide." Ye Han said.

The passages in the cave extend in all directions without any rules. One moment it is a road leading to the sky, and a few steps later it is a small path. The route that seems most likely to lead to the depths of the cave will circle back to the original place after not going very far, going back and forth. The detour caused trouble to the soldiers.

Sometimes it is clear that you only need to go through a narrow passage to reach the next target, but people can often climb through the passage, but the wide power armor cannot get through it anyway, so the soldiers can only find other feasible paths.

Although there were only a few people entering the cave, there were many ways to widen the passage. However, in order not to disturb the wolves that might be present, Ye Han and others invariably chose to take a detour.

After constant attempts, the team finally found the correct route, but because of the obstruction of the cave wall, no one found that the team's direction was exactly the same as the direction of the water flow.

Going around and around in the cave, it is difficult to calculate how far they have walked. It is probably about three to five hundred meters away. Ye Han suddenly heard the sound of gurgling water.

As soon as they entered the cave, they encountered an underground river. Everyone didn't pay attention to the sound of the water at all. However, the sound of the water became louder as they walked forward. It was difficult for the soldiers not to pay attention, but they looked around again and again. Not even a hint of cash.

Ye Han simply stopped messing around and directly ordered the troops to go in the direction of the flowing water.

After walking around several stone pillars, the sound of water suddenly increased. Liu Bin glanced around but found nothing: "Grandma, where did such a big noise come from?"

"Could it be an echo?" Xue Ju asked.

Liu Bin felt that this guess made some sense and nodded, "It's possible..."

Just halfway through the word Neng, there was a sudden crash, and then a long-drawn scream was heard in the ears, the kind of long-drawn scream that occurs when falling from a building or a cliff.

"Xiangzi!"

"Xiangzi..."

Several voices shouted at the same time, and the radio was in chaos.

Ye Han's expression changed: "What's going on?"

"Report, Xiangzi fell!"

Liu Bin was shocked and angry: "Where did it fall?"

Xiangzi is a member of his team, named Du Jixiang. Because there is a character for Xiang in his name, everyone calls him Xiangzi. Except in formal occasions, his real name is rarely mentioned.

Liu Bin heard a thud in his ears, like something crashing into deep water from a high place, and then heard the soldier's answer: "There is a hole here..."

Ye Han immediately said: "Everyone, pay attention, don't move where you are, leave one person in front, and everyone else pull back!"

Based on what he already knew, he had automatically made up for the previous situation.

The bottom of the hole beneath your feet is almost like a floor slab, just a layer of stone slabs. Under the stone slab is probably the underground river. The hole where Xiangzi fell is the passage connecting the upper and lower holes. It is probably the weakest point of the stone slab.

The thickness of the stone slab is unclear at the moment. If everyone gathers near the hole, it is very likely that the fragile stone slab will be crushed. Then it will not be as simple as Xiangzi falling alone.

The soldiers in front quickly withdrew. The strict training made them instinctively walk together. However, after taking only two steps, Ye Han stopped them and ordered them to disperse and retreat.

After the soldiers walked away, Ye Han approached the irregular hole alone and looked into the hole. The sound of water in his ears suddenly became louder.

It was pitch black below, and the night vision goggles couldn't see what was going on below.

I looked back at the hole and saw that the edge of the hole was full of uneven stubble. The thickness of the stubble was no more than three millimeters.

However, the stone slabs around the hole thickened rapidly, and the thickness of the stone slabs one step away was no less than half a meter. It was obvious that Xiangzi was unlucky and happened to step on the thinnest place.

"Liu Bin and Xue Ju come here, the others are on standby." After speaking, Ye Han raised his head and asked the soldier who was left behind, "Xiangzi fell and there was no movement?"

"No."

"Keep calling." Ye Han knelt down on one knee, broke out a bright green fluorescent stick and threw it into the hole.

While the fluorescent stick was still in the air, Ye Han saw a broad surface of calm water with rippling waves. It was not an underground river at all, but a large underground lake of unknown size!

Ye Han could only see a little bit of the lake shore from where he was. Using the compass, he determined that it belonged to the east shore of the underground lake.

The fluorescent stick quickly approached the water and fell into the water with a pop. Due to the conduction of light by the water flow, the nearby lake suddenly became much brighter.

The buoyancy force offsets the falling momentum of the fluorescent rod, and the fluorescent rod gradually floated up in the water. Ye Han's eyes were like a sensitive radar, using fluorescence to scan the lake below to find traces of Xiangzi.

Wearing heavy power armor, it is impossible to float on the water after falling into the water. However, the space version of the power armor has excellent air tightness and is much more adaptable to harsh environments than the Army version. Even if it sinks for several seconds, The ten-meter-deep water bottom can also protect Xiangzi's personal safety. As long as Xiangzi walked to higher ground, he would be able to reach the shore sooner or later. At most, it would be because the water layer blocked the radio waves and the communication was temporarily interrupted.

Moreover, the space version of the power armor has a built-in propulsion device. This thing has very little thrust. It was originally used for space walking and is of no use on the ground. But underwater, it is a good propulsion device.

It was pitch black in the cave, and the situation underwater was even worse. Xiangzi could definitely see the fluorescent stick on the surface of the water. Even if he couldn't see clearly what it was, he should have guessed that the thing on the surface was a fluorescent stick, and controlled the propeller to swim in the direction. Light sources can also get out of trouble.

Liu Bin cautiously approached Ye Han and peered down. When he saw the underground lake, he immediately understood the current situation: "Chief of Staff, are you here?"

"not yet."

"Isn't this kid fainted?" Liu Bin said worriedly.

Liu Bin is by no means a random guess.

The starting height of men's high-altitude diving is 23-28 meters, and the athlete's entry into the water is between 78 and 100 kilometers. At such a high altitude, the moment the athlete enters the water, the impact of the water is equivalent to driving a car at 100 kilometers per hour. It hits the wall at a high speed, so you have to enter the water feet first.

The human high-altitude diving record is 61 meters, but the diver broke his spine.
