Steel Steam and Flame

　　As for Cassia and the others, who were in the mine tunnel space, of course they would also become corpses floating in the water. If you don’t hurry up, I’m afraid that even if the disaster on the spider building is avoided, in Nolida’s plan, this should be the last step, and it will make all the fish that slip through the net in the cavity of the mine tunnel. Be wiped out.

　　 They need to find the nearest entrance and exit to escape the underground mine space completely, otherwise the harvesting sickle held by the **** of death will remain on their necks, and harvesting life is as simple as cutting grass.

　　 But Kara and the others knew the only entrance in the Frost workshop. It would take more than half a day to get there from the center of the mining area and expand the state of the cross pupils. However, the water poured in by Moon Lake would not give them this opportunity. The water did not flow into this cavity slowly with the force of nature in its natural state. But under unimaginable pressure, the unmetered water was forced in madly, so that the air here was also occupied by a large volume of water that was suddenly poured in, causing the air pressure to rise quickly. The lungs feel obvious. They are not breathing air now, but air is burrowing into their alveoli.

"It's already started. We have to find a way. The entrance to Frost is obviously impossible." Gustin opened his mouth to speak. There was a strong gust of wind around, dusty, and the bottom of Moon Lake was rotten. The taste, they were all brought down by the water.

　　 The gust of wind was not blowing, but at a sudden moment, it was like an avalanche of power, with a huge volume of water rumbling, and the sound of hitting the ground with absolute strength rolled from behind them. The air became the repelled object in this enclosed space, crushing crazily toward the place with lower air pressure. At this time, the wind reached its extreme, which was equivalent to a tornado. The sand and small stones on the ground were all swept up by the wave-like wind and slammed into the invisible dark world ahead.

The blowing air is filled with ice-cold water vapor, and there are countless odors mixed in it. Through the thick face mask, you can also smell the odor that cannot be removed-fishy smell, rot, fermentation, and countless substances The chemical odors generated by the interactions all follow the wind everywhere.

　　 The time on the mechanical watch was moving every minute and every second. Carla and the others seemed to have no other way except to run in the direction of the Frost workshop. The sound of the water sweeping from behind is getting closer and closer to them, and the intensity of the moisture and flavor carried by the wind blowing from behind is also explaining this fact to them. Not much time is given to them.

　　 A large volume of water was poured in in a short time, and the air pressure rose by a step. In the center of the original mining area, a huge hole had already been broken in the rock formation on the sky dome, and the white-flowered water column impacted the hard ground below and the remains of the spider building on the ground that still had blue arcs from time to time.

　　 At this moment, the rock formation on the side of the cavity could no longer withstand the strong impact of the current, and a large piece of rock suddenly fell off. Then, like the collapse of dominoes, a chain reaction is inevitable. Just as huge cracks were created on the intact rock, white torrents had already sprayed out through the crevices. After a few minutes of breathing, the impact force of the torrents caused pieces of rocks to fall from the sky. The chain reaction that could no longer be stopped made the broken hole more than ten times larger in just tens of seconds.

　　 So in the enlarged hole, the water flowed more frantically, and the stronger impact water flow continued to wash away the surrounding rock formations that were still barely resisting. The cracks produced faster and the chain reaction became stronger.

　　 This has become an endless loop, and it can only be stopped when the mine tunnel space is filled with water in the moon lake.

　　 Cassia and the others naturally felt the change in the darkness behind them, but they couldn't help it even if they were anxious. Except for the darkness around, the wind that never stops, even the beam of the bright flashlight can't detect the dense dust around. In the beam, the dust has the power to fly forward because of the flow of air. In Cassia's eyes, the dust in the air was divided into several different flow directions in a big forward direction.

　　 The flow of air is from the high-pressure area to the low-pressure area, no matter where it is, it seems that it will not change. Cassia suddenly stopped, and suddenly remembered the knowledge in the book. Standing still, he fired the bright flashlight, and the beam shot into the air. There was also a dusty wind, but there was a slight deviation between the direction of the wind above and the direction of the wind near the ground.

　　 There is a low-pressure area in the darkness above his head, and its power forcibly changes the direction of the flow of air that should have been forever. In this almost enclosed space, there are only two possibilities for the generation of low pressure areas.

　　 One is a place far away from the center of the mining area. Compared with the central area, there is naturally a low pressure area. The second is the entrances and exits here, which are connected to the atmosphere of the outside world and can never become a high-pressure area.

　　By observing the direction of air flow in the sky, you may be able to find the nearest entrance. The dust all over the cavity generated during mining became the best marker at this time, allowing him to observe the subtle changes and flow of wind direction more intuitively.

　　 The running Kara group saw Cassia suddenly stop, and naturally they came to him.

　　 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 connection at a critical moment.

　　 Klitsch said to Cassia’s profile: "Mr. Cassia, this is really yours, even if you don’t admit it, but many times I have to admire your thoughts and observations. It has always been extremely delicate."

　　 "Thank you, Mr. Klitsch." A smile appeared on Cassia's face with a mask, although no one could see it.

　　 There were several dull noises in the darkness behind him. It was the sound of the rock layer falling off and hitting the ground. The collapse of the mine tunnel space finally began at this time.

　　The wind blows stronger and stronger, the sand hits them rustling, and the power of the bright flashlight beam is 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 a while, the sound rolling behind him has not stopped since just now.

　　 The direction of several people's advancement also changed slightly at this time. They have found the lighthouse in the dark storm, and they can stand by right away.

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

　　 The sound of the wave rolling over in the darkness came again. It was a huge wave of water. They blew their heads and covered their faces when they hit Cassia. The heads of a few people are dizzy, and the power of the water waves is great. It feels like hitting the steel plate when hitting the body. Many internal organs feel hurt, and the bones are crunching, and the pain is accompanied by all kinds of whole bodies. Organizational structure. Arm each other's hands, so that no one will fail to avoid being swept away by the waves. 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 through the water slowed their speed by half, and they had to fight the waves coming from time to time. In the end, when the water flooded Klitsch, the tallest of the people, the time interval only passed by about one minute.

"It seems that most of the rock formations have collapsed, and the injection rate of water is too fast." Gustin swam in the forefront, his feet beat the water rhythmically, he tore off his face mask and said, with a bright flashlight in his hand. The beam of light undulates in the water waves. Except for the high-altitude dust, there is still some dust that hasn't fallen. The ground has been invaded by the ice-cold water, and he stood upright without touching the ground. The water potential rises extremely fast, and the current is getting more and more rapid~www.ltnovel.com~ Under the water surface, because of the terrain, a more powerful undercurrent has begun to form. However, at this time, the exit was also close to their eyes, following the flow of the wind, they had found a strange entrance and exit as expected.

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

"Ugh,,,"

　　 Several people responded later, all of them relieved and accelerated. They climbed the rope ladder, because of the weight limitation, they could only go up one by one, otherwise the rope ladder could not bear their abnormal weight.

　　 Of course, it was still a draw at this time, and Cassia was lucky again to be ranked fifth. But in the end there was still a breathtaking ride through the rope ladder to the underground waterway network.

　　 "I finally came up and left the world with only darkness." Cassia said, lying on the edge of the entrance, the cross pupils disappeared from the eyes at the same time, and the fatigue feeling suddenly emerged from all parts of the body.

On the side of 　　 is the appearance of a weapons workshop, with warm yellow lights above his head, and the Kara group is leaning against the wall as weakly as they are. They need to rest, both physically and mentally. The surrounding area is very quiet, the wind is blowing at the entrance and exit, and the sound of the surging water below seems to be audible.

Cassia suddenly wanted to sleep, her eyelids couldn't open, and her meaning became confused. Then, as if the switch button of the machine was pressed with a "pop", his eyes went dark and he fell asleep~www.ltnovel.com~Welcome Book friends come to read, the latest, fastest and hottest serial works are all at ~www.ltnovel.com~ mobile phone users, please go to read.
