After tasting the soil, Xue Ergou immediately asked Liu Chenhan to order and send a team down to help him clean up the soil.

ground, inside a tent that was built before. Dou Ersen ordered people to arrange a guard, and be sure to monitor it 24 hours a day.

"General, Major Xue and Secretary Liu have already gone to the grave, and a radius of fifty kilometers has been put on guard. Dou Ersen was communicating with General Li Hongzhang in real time in the tent.

"Okay, you can stay put. General Li Hongzhang, who was expressionless, said.

Douersen: "Okay. ”

"Didi...... Didi" Dou Ersen frowned in confusion.

"Sir, it's a message from the commander. The commander asked for a team to be sent down to help clear the dirt. Dou Ersen's intelligent housekeeper captain said.

"Okay, you pass the order on. Douerson thought for a moment and said.

Captain: "Okay, that's been communicated. ”

At the bottom of the robbery hole, Xue Ergou and Liu Chenhan have already dug down about 1 meter and are still digging down.

"Stomp, stomp. Footsteps could be heard not far away.

Knight: "Sir, the squad has arrived. ”

"That's great. Xue Ergou said, seeing the arrival of the team, he directly instructed them to dig down like himself.

Although the "Click......" team has few people, this physical strength is not small at all. With their help small, the excavation work went well.

"Click, sir, there's a situation on my side. A member of the squad said.

Xue Ergou, who was taking a break on the side, saw it, and didn't take a break, and walked directly to the team member.

Xue Ergou: "What's the situation?"

Member: "Sir, I'm digging and digging, and suddenly it's empty down here." ”

"Empty?" Xue Ergou picked up the strong flashlight he carried with him and shone it towards the place where the team member was digging, and found that there were traces of excavation on the ground, and in the center of the traces, there was a swarthy fist-sized hole waiting for me.

After Xue Ergou approached, he stretched out his hand to the entrance of the cave and felt it carefully. The air under the entrance is still circulating, and the inside of the cave is very humid.

"The rest of the team, all stop digging. Your mission is over, and now you can go back. After Xue Ergou felt the hole, he gave an order to the team.

"Roger. The team members packed up their equipment and headed for the ground.

Seeing that the team members were gone, Xue Ergou went to explore the place where several other team members were digging.

Xue Ergou saw that these excavation traces were normal, and he felt that something was wrong about this. So he picked up the sapper shovel and dug hard at a digging mark.

"Click. A swarthy hole appeared, and with the help of Liu Chenhan, Xue Ergou continued to dig on the excavation traces of the other three team members.

"Click. This hole appeared one after another, and even Liu Chenhan felt that this was very abnormal.

This rammed earth that did not dig into the periphery of the ancient tomb, nor did it see the surrounding tomb bricks, and dug out these fist-sized black holes for no reason.

"Secretary Liu, let's dig up this place together. Xue Ergou seemed to remember something, and beckoned Liu Chenhan and the two to dig towards the entrance of the cave together.

In less than an hour, the hole was dug open enough to be a man's width. Xue Ergou took out several glow sticks from his backpack, knocked them on each other and threw them directly at the hole.

Xue Ergou looked down, only to see a slight glow emitted by the glow stick under a hundred meters, Xue Ergou took the glow stick again and threw it around the cave, and then he saw the situation underground.

It turned out that this was an underground karst cave, before the few of them were digging above the dome of the cave, and after digging the dome, the hole was naturally exposed, but fortunately this dome was strong, otherwise the group would have to fall into the cave, thinking of this, Xue Ergou couldn't help but sweat for himself.

Then Liu Chenhan stepped on both sides of the cave entrance and pulled Xue Ergou's trouser belt. Xue Ergou wore a headlamp on his head, half of his body shone downward, and when he confirmed that there was no problem, he motioned for Liu Chenhan to pull himself up.

"Secretary Liu, there is no danger under the entrance of the cave at the moment, I will go down to the cave first, and in case there is a situation, you will be in a hurry to help. Xue Ergou said with a serious face.

Liu Chenhan: "Okay, I will protect you." ”

"Hmm. Xue Ergou said, took out a hundred-meter-long rope from the bag, dug several pits in the thief hole, and buried several U-shaped bolts. The pits dug by Xue Ergou formed several groups of triangles, and the U-shaped latches in the pits were combined with these fixing pits. This 100-meter height is more than enough for a vertical drop.

Xue Ergou took one end of the rope and wrapped it around the U-shaped latch, then filled the latch and the pit with soil, and stepped on the soil. The remaining rope is then placed into a one-person-wide hole.

"Whew, whew, whew...... Ancestor bless!" Xue Ergou buckled the rope into the pulley around his waist and replaced the headlamp with a new battery. Taking a few deep breaths, he nodded to Liu Chenhan, and gently jumped down the one-person-wide black hole with a slight force under his feet.

Seeing Xue Ergou jumping off the black hole, Liu Chenhan was extremely nervous, but he couldn't show it. After seeing Xue Ergou go down, she immediately approached the entrance of the cave to confirm Xue Ergou's situation.

Xue Ergou turned on his headlamp and went down to the back of the black hole. Swipe down little by little in the air.

"Twitter!" A strange sound came from the darkness, and Xue Ergou looked in mid-air towards the place where the sound came from, only to see a group of vampire bats hanging upside down on the dome.

These vampire bats have large bodies, the largest of which is more than 20 centimeters long, with no exposed tail and a predominantly black coat. Their physiognomy looks very ugly, with a nose with a "U" shaped groove at the top, triangular ears, a very short snout, shaped like a cone, long and sharp canines, and a well-developed incisor tooth, slightly triangular, sharp as a knife, which can pierce the protruding parts of other animals and feed them.

Looking at these huge vampire bats, Xue Ergou couldn't help but be a little nervous. Fortunately, these vampire bats seem to have just come back from going out, and Xue Ergou escaped by luck.

"Knight, turn on the magnetic field detection function. Xue Ergou said to the knight as he descended.

Knight: "Yes, sir. This underground space was detected as a karst cave, which was 100 meters high, 1.5 kilometers long and 1.5 kilometers wide. ”

"Okay, I see, any object with a living magnetic field approaches, you have to tell me in time. Xue Ergou was slightly nervous.

Knight: "Yes, sir. The group of vampire bats above his head is currently in a state of fullness, and the chief doesn't need to worry too much. ”

"Hmm. After listening to the knight's words, Xue Ergou was much more relieved.

"Knight, can you still transmit information to the outside world now?" Xue Ergou asked.

Knight: "Sir, you don't have to worry about this, the information transmission function is normal at the moment. ”

"Well, then you tell Secretary Liu to bring some flamethrowers when she comes down. Xue Ergou thought about it as he descended.

Knight: "Yes, sir. The message has been delivered. ”

"Pop ......" Xue Ergou finally landed, and after landing, he first pulled out his gun to guard against it, and then threw several light sticks around, and when the visibility around was high, he confirmed that there was no danger around, and then transmitted a message to Liu Chenhan above.

After landing on the ground, Xue Ergou looked at the underground karst cave with his eyes, and saw that the entire karst cave was full of stalagmites.
