Chapter 32 third quarter

The gates of hell have opened. Everyone stood motionless, staring at the dark hole in fear, like ancient corpses that had been dead for thousands of years. The hot air from the black hole rolled over the cheeks, drilled into the pores, and melted the congealed blood. They seem to have escaped from the hands of the god of death, or they backed up, or uttered horrified cries, and suddenly became a mess. Jin Kun, who was the closest to the relief, took a deep breath, bravely walked to the entrance of the cave, and raised his flashlight to shine a light inside.The beam of light swayed left and right in the black hole, illuminating a row of stone steps that meander down. The stone steps only have a dozen floors, and at the end is a passage that goes deep into the interior.

Jin Kun turned around and greeted loudly: "Everyone, come quickly, this may be the exit!" It wasn't until Jin Kun shouted several times that people gathered around one after another.Xu Juan looked at the hole uneasily, and asked in a trembling voice, "I...are we going to get in here?" "right." "But... this is the mouth of King Yama. If we get in from here, wouldn't we become its prey?" Xu Juan stepped back a few steps, shaking her head like a rattle, "I want to drill you , I... I don't want to go in and die!" Jin Kun was almost stunned by her childish words, and just about to persuade her, he heard Yi Xiaotian yelling loudly: "She is right, we must not get into this hole, otherwise there will be bad luck!"

Jin Kun pointed at the entrance of the cave and snapped, "What? You also think this is the mouth of King Yama?" "Of course not." Yi Xiaotian pointed to the folds on the embossed forehead, "Look, this pattern is the hexagram Gen..." Jin Kun interrupted her, and asked angrily: "Just because the hexagram Gen is engraved on the relief, we can't drill? Is it so evil?" "Xiaokun, listen to me, we really can't drill into this hole." Liu Xie persuaded in an elder's tone, and then explained, "It is said in the hexagrams that when Gen ends, the two mountains overlap. "

"What's the meaning?" "Gen hexagram represents a high mountain. If you have no way to go down the mountain, of course you have to stop." Liu Xie looked at the relief with an expression of awe on his face, "Since the ancients carved Gen hexagram on the relief, it is to remind future generations that this cave There are many dangers in the middle, please stop immediately." Jin Kun frowned and remained silent for a moment, then argued: "But we have nowhere to go now, so we can't just sit here and wait for death?" Zhong Weiguo stood up and echoed, "That's right, instead of sitting here waiting to die, we might as well take a bold risk, maybe there will be a glimmer of life."

Liu Xie stared at the entrance of the cave in silence, as if making a major decision.Tens of seconds later, he stomped his feet vigorously, and said, "That's good! The matter has come to this point, and we can only sneak in." He looked around again, and repeatedly urged, "However, everyone must Be careful, if we encounter danger, we will retreat immediately." Xu Juan still insisted against going into the black hole, but under Jin Kun's persuasion, she finally agreed to go in.As a result, everyone got into the black hole one by one, and their whole bodies were immediately wrapped in warm air, as if they had stepped from the cold winter into the midsummer.They carefully stepped down the stone steps and walked into a not-so-spacious corridor.The two walls are neatly built stone walls, and long strips of boulders are erected on the three-meter-high ceiling, which is obviously an artificial corridor.

The hot air wrapped around their bodies, making them feel extremely uncomfortable, as if they were really passing through the belly of the devil at this moment. The "Black Panther"'s long tongue sticks out of the mouth, which is more conducive to heat dissipation.People's faces were covered with hot sweat, and soon their underwear was soaked, so they had to take off their outer clothes and march in only thin underwear. "Damn it! Why is this place so hot? It's almost as hot as the sauna room." Xie Hu, who was walking in the front, cursed. He couldn't stand the high temperature, so he took off his underwear and went shirtless.

Zhong Weiguo, who was walking side by side with him, stopped, first squatted on the ground and touched it, then stood up, touched the stone walls on both sides from bottom to top, and calmly speculated: "The temperature on the ground is obviously higher than that on both sides." The stone wall is high, and the higher the stone wall is, the lower the temperature is. From the perspective of heat transfer, the heat energy is conducted from the ground.” "Strange, why is there such a high heat energy underground?" Xie Hu also knelt down and touched it, as if touching a hot water cup.He jumped up like an electric shock, looked nervously at Zhong Weiguo and asked, "I... we are walking on the crater, right?"

People broke into a cold sweat when they heard Xie Hu's guess, as if they were really walking on the crater at this moment, and the volcano under their feet would erupt at any time, spewing out hot magma, which would instantly melt them into ashes.People were in a panic, and some even suggested turning around and going back immediately. Zhong Weiguo quickly squeezed into the crowd and said loudly: "Everyone, don't panic! Based on my experience, it is impossible for us to have a volcano under our feet." "It's not a volcano? Then how can this underground heat be explained?" Xie Hu asked.The others were also nervous and asked random questions.

Zhong Weiguo signaled everyone to be quiet, and then explained: "If I guessed correctly, there should be an iron ore deposit with extremely high iron content underground, and there is a strong alternating magnetic field under the iron ore. This strong magnetic field will make The iron ore produces eddy current①, which causes the iron molecules in the iron ore to move irregularly at high speed, and the iron molecules rub against each other and collide to generate huge heat energy. To put it bluntly, this is similar to the principle of induction cooker heat generation. But, after all What causes the strong magnetic field, I cannot guess."

『①Eddy current: electromagnetic induction acts on the alternating current induced inside the conductor. 』 After hearing these words, everyone let out a sigh of relief.But Xie Hu still had a question, so he asked, "Professor, stone is a very good conduction medium. How can there be a huge temperature difference between the ground and the stone wall?" "You're on to something." Zhong Weiguo greeted everyone to move on, and said: "The temperature in this corridor is very high, but the air is very humid. If the temperature is always this high, the moisture will evaporate long ago. Therefore, according to my analysis, the heat energy in the ground should have been generated not long ago. , so that it has not yet reached a relatively balanced temperature.”

Xie Hu suddenly realized, and said: "You mean, the temperature will continue to rise?" "Yes! Don't you feel that the soles of your feet are getting hotter and hotter, even a little hot?" Xie Hu really felt the soles of his feet burning, as if stepping on a red-hot iron plate.He reached out to wipe the sweat off his face, and said anxiously, "If the temperature rises by dozens of degrees, wouldn't we be roasted into meatloaf?" "Dozens of degrees? I'm afraid if you raise it another ten degrees, you will collapse, and then go into shock and pass out!" Zhong Weiguo turned his head and urged loudly, "Hurry up, everyone, try to move as fast as possible." The temperature is getting higher and higher, and the humidity of the air is getting heavier. Everyone's clothes are almost completely soaked. It is difficult to judge whether it is because the temperature is too high and the sweat is soaked, or because the air humidity is too high and the humidity is wet. Everyone's physical energy was exhausted, and they were all sore and exhausted. They wished they could lie on the ground and never wake up. Fortunately, the experienced Zhong Weiguo reminded everyone to concentrate so that no one would fall down.They supported each other, walked with difficulty, stopped talking to each other, and didn't even bother to swear. Just when everyone was in deep despair, the flashlight suddenly caught a figure.
