Steel steam and flame

As for Cassia and the others who were in the mine space, they would naturally turn into corpses floating with the water. If we don't hurry up, even if we avoid the disaster on the spider building, this should be the last step in Nolida's plan, and all the fish in the mine cavity will slip through. be wiped out.

They need to find the nearest entrance and exit to completely escape from the underground mine space, otherwise the harvesting sickle held by the God of Death will still be placed on their necks, and harvesting life is as simple as mowing grass.

But the only entrance Kara and the others knew was the one in Floss's workshop. It would take most of a day to get there from the center of the mining area with the cross-pupils unfolded. But the water pouring in from Moon Lake will not give them this opportunity. The water is not in a natural state and slowly flows into this cavity with the power of nature. Instead, under unimaginable pressure, unmeasured amounts of water were crazily squeezed in, so that the air here was also occupied by the large volume of water that was suddenly poured in, causing the air pressure to rise quickly. Cassia and the others The lungs feel obvious. They are not breathing air now, but air is drilling into their alveoli.

"It's already started. We have to find a way. The entrance and exit from Flos is obviously impossible." Gustin opened his mouth to speak, and a strong wind blew around him, bringing with it dust and rotting accumulations at the bottom of Moon Lake. The smell, they were all brought down by the water.

The strong wind did not blow up, but in a sudden moment, it was as powerful as an avalanche, carrying a huge volume of water that roared, and the sound of hitting the ground with absolute force rolled from behind them. The air became something that was rejected in this closed space, crushing crazily towards places with lower air pressure. The wind force reached its peak at this time, which was equivalent to the state of a tornado. All the sand and small stones on the ground were swept up by the wave-like wind, and they were suddenly slapped towards the invisible dark world ahead.

The air that blows in is filled with cold water vapor, and there are countless smells mixed in it. Through the thick mask, you can smell the smell that cannot be eliminated - fishy smell, rot, fermentation, and countless substances. All the chemical smells generated by the mutual reactions are carried everywhere by the wind.

The time on the mechanical watch was moving minute by minute. Kara and the others seemed to have no other choice but to run in the direction of Floss's workshop. The sound of the rushing water coming from behind was getting closer and closer to them, and the intensity of the moisture and smell carried by the wind that kept blowing from behind also explained this fact to them. There isn't much time left for them.

A large amount of water poured in in a short period of time, causing the air pressure to rise to another level. In the center of the original mining area, a huge hole had already been opened in the rock formations on the sky. The white pillars of water hit the hard ground below and the remains of spider buildings still emitting blue arcs from time to time on the ground.

At this moment, the rock formations on the edge of the cave could no longer withstand the strong impact of the water flow, and a large piece of rock suddenly fell off. Then, like the toppling of dominoes, a chain reaction is inevitable. As soon as the huge crack was created on the intact rock, the white torrent splashed out through the crack. In a few short breaths, the impact of the torrent caused rocks to fall from the sky one after another. The unstoppable chain reaction caused the broken hole to expand more than ten times in just a few dozen seconds.

As a result, the water flow pushed in even more crazily in the enlarged hole, and the stronger water flow continued to wash away and compress the surrounding rock formations that were still barely resisting. The cracks were generated faster, and the chain reaction became stronger and stronger.

This has become an endless loop that can only be stopped when the mine tunnel space is filled with water from the Moon Lake.

Cassia and the others naturally felt the changes in the darkness behind them, but there was nothing they could do even if they were anxious. In addition to darkness, there is the wind that won't stop. Now even the beam of a strong flashlight can't penetrate the dense dust around him. Inside the beam, the dust has the power to fly forward due to the flow of air. In Cassia's eyes, the dust in the air was divided into several different flow directions in a large forward direction.

The flow of air is from areas of high pressure to areas of low pressure, and this does not seem to change no matter where it is. Cassia suddenly stopped and suddenly remembered the knowledge in the book. Standing still, he turned on the strong flashlight and fired the beam into the air. There was also dusty wind there, but the flow direction of the wind above was slightly different from the flow direction of the wind close to the ground.

There was a low-pressure area in the darkness overhead, and its power forced the air flow that should have been going forward to change its direction. In this nearly closed space, there are only two possibilities for the generation of low pressure areas.

One is that it is far away from the center of the mining area. Compared with the central area, it naturally becomes a low pressure area. The second is the entrance and exit here, which is connected to the atmospheric pressure of the outside world and can never become a high-pressure area.

By observing the flow direction of the air at high altitudes, you may be able to find the nearest entrance or exit. The dust produced during mining that spread throughout the cavity became the best marking agent at this time, allowing him to more intuitively observe the subtle changes and flows of the wind direction.

When the running Kara group saw Cassia suddenly stop, they naturally came to his side.

They looked at the beam of light that Cassia shot into the air, and smiles appeared on their faces after a few seconds. Everyone's theoretical knowledge is not bad, the only difference lies in how to use it and how to remember the connections at critical moments.

Kritins said to Cassia's side face: "Mr. Cassia, this is really yours. Even if you don't admit it, I have to admire your thoughts and observation strength in many cases. It has always been extremely delicate."

"Thank you, Mr. Kritchens." Cassia's masked face also showed a smile, although no one could see it.

Several more dull sounds came from the darkness behind him, which were the sounds of entire rock formations falling off and hitting the ground. The collapse of the mine tunnel space finally began at this time.

The wind became stronger and stronger, the sand grains rustled on their bodies, and the power of the bright flashlight beam was further reduced.

"Speed ​​up and know the method, but it doesn't mean that we can leave here safely. Without seeing the sun outside, we are still in danger." Gustin looked at the direction of the air flow in the sky and reminded After saying this, the rolling sound behind him has not stopped since just now.

The direction of the few people's progress also changed slightly at this time. They had found the lighthouse in the dark storm and could stand next to it.

It was already an hour later when knee-deep water swung under my feet. The cold water seemed to have just melted from the ice on the top of the mountain. A minute later, the knee-high water suddenly rose to waist height in a wave. The speed of the water had seriously affected their progress, and their physical exertion also began to increase at this time.

There was another sound of rolling waves in the darkness. It was a huge wave of water that hit Cassia and the others. Several people were in a state of confusion. The force of the water wave was so great that hitting the body felt like hitting a steel plate. Many internal organs felt hurt, and there were creaking sounds in the bones. The pain was accompanied by various pains all over the body. organizational structure. Holding hands with each other, no one is left behind, lest they be swept away by the waves. In the past few times, several people were almost washed away because they were not prepared for these waves. Under the power of nature, even the surgeon is as frightened and helpless as an ant facing a behemoth like a human being. Compared with ordinary people, they are just a few stronger ants at best.

Wading forward slowed their speed by half, and they had to fight against the waves from time to time. When the current finally submerged Krichens, the tallest of the group, the time interval was only about a minute.

"It seems that most of the rock formations have collapsed, and the water was injected too fast." Gustin swam at the front, pumping the water with his feet rhythmically. He took off his mask and said, holding a strong flashlight in his hand. The beam of light undulates in the water waves. Now, except for some dust that has not fallen from the sky, the ground has been invaded by bone-cold water. Even if you stand upright, you can't touch the ground. The water potential is rising extremely fast, the speed of the current is getting faster and faster, and a more powerful undercurrent is beginning to form under the water surface due to topography. However, the exit was right in front of them. Following the direction of the wind, they unexpectedly found a strange entrance.

"Did you see the big rock pillar in front? There is a rope ladder on it, and the entrance and exit are on top!" Gustin turned his head and shouted to Cassia and the others behind him, with indescribable excitement. He stayed here for the longest time, even for a minute or a second, and he didn't want to breathe the smelly and rotten air around him anymore.

"well,,,"

Several people responded from behind, breathing a sigh of relief and speeding up. They climbed up the rope ladder. Due to weight restrictions, they could only climb up one person at a time, otherwise the rope ladder would not be able to bear their abnormal weight.

Of course, lots were still drawn at this time, and Cassia was once again lucky enough to be ranked fifth. But in the end, we managed to get up to the underground water network through the rope ladder without any danger.

"I finally came up and left the world of darkness." Cassia said while lying next to the entrance. The cross pupils disappeared from her eyes at the same time, and the feeling of fatigue suddenly emerged from all parts of her body.

Next to it was what looked like a weapons workshop, with warm yellow lights overhead. Kara and others were slumped against the wall. They needed to rest, both physically and mentally. The surroundings were very quiet, the wind was whistling at the entrance and the sound of the water flowing below could also be heard.

Cassia suddenly wanted to sleep so much that he couldn't open his eyelids and began to feel confused. Then it was like the switch button of a machine being pressed with a "pop" sound. His eyes darkened and he fell asleep.
