This is still a big broken pot. Seeing these yellow erosive Fangqi, he immediately opened a window: "lying trough, developed!" It seems like what he thought, here is a big iron ore, iron ore with such high purity, it is simply a gold mine. It was probably because the coal seam was too thin that the coal and the iron ore above could not be effectively pasted together.


    But his exclamation came from the gas mask and fell into the ears of the little five and six brothers. They didn''t hear what Fang Qi said clearly and thought he said badly. Fang Qi asked if he wanted to move on. The three came prepared with gas detection instruments. The indicator light was still green, indicating that there was no problem.


    Fang Qi nodded to them, indicating that they must pay attention to the detector. If the light is red, they should quickly withdraw. The three men climbed in along the undulating coal pile. After they walked out for hundreds of meters, the slope gradually slowed down, and the top of their head was still mixed with yellow and black.


    It was not until they stepped down from the coal pile that they were relieved. The original collapsed section was in the middle. Later, the wood support was good. It may be that the development area over there is too large, and the obvious surface entering here is much smaller, so they failed to completely collapse.


    Fang Qi took off his mask, took out his walkie talkie and shouted a few times. The electric current of the rusty walkie talkie sounded for a while, and then someone said, "who is it?" Fang Qi said it was the headquarters and asked if anyone was injured. The man replied, "I''m the foreman. No one has been injured yet. However, our machine has drilled a big hole. It''s very dark inside. I don''t know what''s inside."


    The three men were relieved and asked him to report the gas concentration. The foreman said there was no gas at all because the wind blew in the drilled hole. Fang Qi ordered, "well, count the number and retreat in an orderly manner."


    The foreman replied yes, and then there was a yell. After a while, Fang Qi and others saw the flashing light coming this way. It was not far away for a few hundred meters. They arrived soon, but they didn''t know Fang Qi. However, after listening to Xiao Wu''s introduction that it was the boss behind them, they put down their doubts and climbed to the coal mountain according to the order to evacuate.


    Xiao Wu looked at them and asked Fang Qi, "aren''t we going?" Fang Qi asked the brothers, "I want to go in and have a look. If you don''t dare to go, you can withdraw with them." The two brothers looked at each other and said, "boss, we''ll follow you wherever you go!"


    Fang Qi said faintly, "follow me. You may crash. Aren''t you afraid?"


    Little five''s chest stood up: "boss, we are not afraid of going up the knife mountain and down the sea of fire. We are afraid of drilling a hole and afraid of a bird." Xiao Liu also said, "don''t worry, boss. Our brothers go in with you and go out with you. We don''t trust you to go in alone. "


    Fang Qi didn''t say, "well, run with me." Sure enough, before he went far, he could vaguely feel the cool breeze blowing from the depths of the hole. It was like a space sealed for a long time. It was mixed with strange smells that could not be explained clearly. Fang Qi could not tell what kind of things sent out.


    When they reached the increasingly narrow mine, they saw a big hole at the end of the dark and shining coal seam, and two coal drills were left aside. This thing is huge and can only be operated by three or four people. It looks like an enlarged percussion drill.


    The wooden support has been hit to the front. Several holes have been dug on both sides of the mine. There are peel and paper scraps scattered inside. This is their resting place. Fangqi said to them, "you two stay here, but you must not smoke. If we burn the coal, we will all be finished."


    Two people answered, not at ease: "boss, you can go in alone, or we can follow in, or we can take care of you." Fang Qi smiled faintly, "forget it, you two go in. I''m afraid you''ll drag me down." They had to say, "then you have to be careful."


    It''s not the first time Fang Qi has drilled a hole. I haven''t seen any strange things. Of course, this hole is nothing. I remember when he and Miao Miao crossed the past, they also drilled into the ground from this place. They also found a dragon shaped creature deep in the hole. Time has changed. I don''t know whether the hole is connected with the hole under Chishan City, and whether the dragon shaped creature is still there.


    Before selling the mine, he must find out what is in the cave and extract the maximum value of the mine.


    Holding the big miner''s lamp, he stood at the mouth of the cave and looked down. Sure enough, as the foreman said, he couldn''t see anything clearly or hear anything below. Fang Qi simply took a miner''s lamp and shone at his feet. Only then did he find that the hole protruded forward and was not wide on both sides. Probably the foreman only looked forward and down, not on both sides, and the hole was not reflective, so he subconsciously thought the hole was too big.


    In fact, Fang Qi can see very clearly. The two sides are only more than ten meters wide. There is a big crack in the middle, but it is very deep below. Although the location of the hole is tricky, it is difficult not to defeat him. Fang Qi put down the headlamp, put on the miner''s hat, turned on the miner''s lamp, grabbed the rock near the hole with one hand, reversed his waist, moved to the rough stone nearby, and climbed down from the stone surface. I haven''t used this scorpion''s method of climbing the wall for a long time. It''s a little rusty, but I''ll be much more skilled after climbing down for a short period. Not long after he climbed down, there was a hole below. Fang Qi jumped down and the miner''s lamp on his head shone around. It was not a dark coal seam, but a rusty yellow. The whole hole was full of twists and turns and could not see the end.


    At this hole, the walkie talkie that was still ringing seemed to be disturbed by something, sending out a crackling sonic boom. It''s useless anyway. Fangqi just turned off the walkie talkie. But at this time, what makes people feel painful is that the light of the miner''s lamp is rapidly turning yellow until it flashes twice and goes out directly. It''s not surprising that in a huge iron hole, I don''t know whether it will form some kind of electromagnetism, and the loss of power is certain.


    Anyway, Fang Qi could see clearly even without lights. He simply turned off the miner''s lamp and walked hundreds of meters along the hole. Although the wall of the hole is also very rough, it is much more regular than the stone hole. After walking for a while, the scene ahead changed greatly. At first, he didn''t think there would be an adventure in the depths of the cave. But when he saw the two bird seal characters "underground Furnaces" on the cave wall, he felt that his imagination was too poor. It''s like a popular saying on the Internet that poverty limits our imagination.
