"It's possible," Shima said, "but if that's the case, then it's probably man-made." Moreover, the flight away of the supersonic bat is the result of this person's deliberate expulsion, and a person who secretly enters this cave is definitely not to drive away the supersonic bat, which means that this person should have another purpose for the mine. ”

"Is there another purpose", Xiao Wai said lightly: "I am afraid that the only thing that can be associated with the rock iron charcoal pit is fossils, it is said that the head cover dragon, war hammer dragon, fossil pterosaur and ancient air eavelacanth of the owner of the rock railway hall are all recovered from the fossils found in this pit." ”

"This is true", Genta said, "It was still early when the scoop man discovered the fossils of the craniosaurus, and I have not seen them, but the fossils of the fossil pterosaur and the ancient alecanthus were found in front of our eyes, and I am still very impressed." ”

"So have fossils been found in this direction?" , Xiao Jing asked, pointing in the direction of the survival of the supersonic bat.

"Well, it doesn't seem to be, because there are usually too many supersonic bats here, which causes the cave here to be filled with all kinds of ultrasounds. Although humans can't hear this ultrasound, it still feels uncomfortable when you get close, so it is generally impossible to find fossils when no one comes. ”

"That's strange, since no fossils have ever been found in this direction, what is this man driving away the supersonic bats?" While speaking, Xiao Jing pointed to the bat feces on the ground and said: "And, you see, there are no footprints on the supersonic bat feces on the ground, so how did this person get in, or is it that the purpose of this person to drive away the supersonic bat is not to enter here at all." ”

"It's also possible that this person doesn't exist at all," Shima said next to him.

"It's very unlikely," Xiao Wai said lightly, "If there is no one here, then the sound should be naturally generated, and to be able to scare away the supersonic bats, there must be a real change to change the reflection of the ultrasound waves, but there is no obvious change here." ”

"Hmm", Xiao Jing suddenly seemed to think of something, turned his head to Yuantai and asked, "Mr. Yuantai, may I ask if there is a night shift in the Yantie Charcoal Pit?" ”

"The night shift, this is there," said Genta, "The rock iron carbon pit works 24 hours a day, and the working system is three shifts and two shifts. ”

"Well, that is, there are 24 hours of people in the rock and iron pits," Xiao nodded and then asked, "Then Mr. Genta, under what circumstances will you miners be evacuated directly outside the mine?" ”

"Well, according to our mine management manual, there are still a lot of situations," Genta said, "Because the mine is a dangerous space, once it collapses, it may directly take human life, so whether it is abnormal vibration, noise or abnormal activity of the spirit, we will retreat to the outside of the mine." ”

"I see," Xiao Jing smiled, and then asked, "Then have you recently had anything unusual that caused everyone to evacuate outside the mine?" ”

"There is this", Genta nodded and said, "It seems that there have been seven or eight times in the past month, the ground shaking, loud noises, and sudden water currents, and some elves escaping. These things are all there, but every time, Mr. Ryota came in to inspect and found no other abnormalities, and after waiting for professional inspectors to come to test, no abnormalities were found, and we started work again. ”

"Is that so", Xiao Jing nodded, and then asked, "Then how long does it take from your evacuation to the completion of the testers?" ”

"This", Yuan Tai said, "It depends on whether those inspectors have time." The place where these inspectors are stationed all year round is not far away, just in Yantie City. Under normal circumstances, it would not take long to come here to complete the test, and after contacting them, it will be almost done in about three hours. However, the strange thing is that except for the first time, at other times, these inspectors are busy every time something happens, and it has been two or three hours since they came over. ”

"That's the case", Xiao Jing said with a smile: "Then I have a guess, whether it is the collective flight of the supersonic bats this time, or the vibration, noise, flowing water and so on in front, it is actually to get you miners out of the mine." ”

"To get the miners out of the tunnel?" , Shima said in surprise: "What are you doing to get the miners outside?" ”

"This", Xiao Jing said solemnly: "It's very simple, it should be that these people have taken a fancy to something in the rock iron charcoal pit, and they don't dare to come in and collect it openly, so they will make you leave the mine by creating these abnormal phenomena, and then seize the time to mine." And you don't dare to re-enter the mine before passing the test, so they will create an event here before creating an event in other places, so that the inspectors can't be separated, so that they have enough time to dig. ”

"This is impossible," said Mr. Genta, "our pit entrance is guarded, so how can it be possible?" ”

"Do I have to go through the hole to enter this pit?" Xiao Jing said: "Maybe they have already dug a passage to this charcoal pit, but there is some cover, so you didn't find it." If my speculation is correct, then by now, those people should still be in the pit, let's look for it together, and if we can find it, we will be able to prove my speculation. ”

"Then I'll go and call the workers right away, there are many people, and I'm sure I'll be able to find those people soon," Genta said, heading towards the entrance of the cave.

"I don't need this one," Xiaojing said, "until my speculation is proven, it is always speculation, how can I make them all take risks because of a speculation that may not be dangerous." Let's find it ourselves. ”

"However, it would be too difficult for the five of us to find someone in such a huge mine," Genta said.

"It's easy", as he spoke, Xiao Jing took out Lucario's Poké Ball and threw it out, "Go, Lucario, check if there is a waveguide display in this mine." If I'm correct, those people should be around here, after all, it's easy to spot if it's too far away. ”
