"Since we came in, we haven't seen anything alive except some fish in the water when we first entered the hole. This is very abnormal."

Quinn and I nodded. Brother donkey continued with a look of management: "even underground, there should be a complete ecosystem. This kind of silence is too abnormal. I just told you two that I don't want to cause panic in the team."

Quinn immediately told everyone to be careful and said to his men, "Hey, brothers, there may be powerful things in this hole. Be more careful, everyone. Don't act alone in a group of four." everyone said that they received it. The courage of soldiers and the delicacy of women, and finally equipped with high-tech equipment can ensure that we can live in various actions to the greatest extent.

This time we dived into the water, and the diving time was longer and deeper than ever before. If we hadn't just rested and supplemented energy and food, swimming such a long distance would really make me tired. Because I was reminded by brother donkey before, Quinn ordered to group and take care of each other. Of course, I took brother donkey, who made these mercenaries a little headache, and Sanmei sandwiched him in the middle, followed by Ivan.

Halfway through the dive, the foremost sea snake and others found that there were signs of manual excavation in some places. They turned back and sent us a signal with a flashlight. Everyone couldn't help but be happy and gave each other a thumbs up to indicate that we were looking for the right place.

After crossing the arched exit, there are more and more traces of artificial construction in the caves in the water, including steps covered with water and grass, incomplete murals, broken animal statues, some look like tigers or leopards from their heads, and some are in the shape of snakes. Most people didn't care about these. Only Sanmei and brother donkey looked at them, didn't stop too much, and soon followed up.

Because of their delay, I fell at the end of the line. When I put my head out of the water, most people had climbed up. After climbing up the stone platform with the hard and powerful hand of shopkeeper Qian, I noticed that several brothers in the outermost area were kneeling with guns, with a serious fan on their face. All the muzzle of the guns were inclined upward at an angle of 45 degrees, as if they were preventing something in the air.

"What's the matter? There's something moving?" I got nervous and pulled the assault rifle to my chest.

Quinn pointed to a corner of the stone platform and said meaningfully, "the road is beginning to be difficult to walk". Following his fingers, I saw a brother lying there, and the team doctor was kneeling beside him.

When I turned back and picked up Sanmei and brother donkey, the team doctor was basically over. He came over with an animal body, handed it to Quinn and said, "I was bitten by this thing and gave a lot of blood, but it's all right."

By the light, it was a bat. It had been hit by bullets. With its mouth open, its two sharp teeth were exposed. It looked a little like dying in peace. But this thing is very familiar to us who march and fight all year round. It doesn't pose a great harm at all. We carry some rabies bacteria at most. We have also been vaccinated.

Facing our puzzled eyes, the team doctor washed the blood from his hands in the pool and explained: "This one looks a bit like an ordinary South American vampire bat, but it should be a close relative or a variant. Because usually, the saliva of South American vampire bats contains an enzyme that can prevent platelets from clotting and keep bleeding in the wound so that they can eat, but there is always a time limit. But in front of this one, I don't know whether it is a special species or what is the reason for the enzyme that prevents coagulation The strength is almost ten times that of ordinary blood sucking bats. It was only after cutting off some wounds and stitching that it was barely stopped. Fortunately, it was the face that was bitten... "

"They're coming again." with the cry of a brother at the periphery, countless black and red bats flew in from the depths of the channel and rushed towards us like a stream of black smoke.

"Free fire" At Quinn's command, there was a dense gunfire in the cave, and rows of bullets hit bats and fell like raindrops. But these things soon dispersed and flew along both sides of the cave and the stone walls of the cave bed. In this way, only the outermost brothers dared to open fire. We were worried about hurting our companions in the inner layer. We had to wave a military knife with one hand and protect our face from being bitten.

However, it was difficult to cut off all these flexible flying things with a saber alone. Soon someone was bitten and screamed. Sol showed the light flamethrower and shot several flames. A lot of bats fell to the ground with the flames. The brothers on the inner floor immediately squatted down and shot with a gun, which finally stabilized their position. The team doctor immediately stopped the bleeding of the wounded with the method just now and looked at them There are too many people to help.

Everyone immediately put on the helmet and gloves of the nano suit, and only two eyes and one mouth were exposed from top to bottom. The attack area was much smaller this time, so we could deal with those air threats more safely. This time, we used the formation of double sharp soldiers. The first two brothers opened the road with shotguns. When they met groups of bats, they roared with 12 caliber steel ball shrapnel before us Bullet casings and bat corpses almost fell on the road. This still depends on high-tech equipment. Otherwise, the sharp teeth and special antithrombin of these little things must cause us great trouble.

At the end of this passage, there is a deep underground cliff. There are countless honeycomb shaped holes on the top of the head, which are distributed on the stone wall. There are bats flying in and out. We all look at each other and realize a very serious problem. With our hands, it is difficult to kill all these thousands of bats, and under their attack, it is difficult for us to climb the mountain by hanging in the usual way The rope crossed the cliff.

According to normal habits, bats are afraid of fire and light. We studied it and decided to send shopkeeper Qian, who is not very dangerous all the way, to take the lead because he is more resistant to bite. First, he hit two sets of ropes with empty bullets and nailed them to the rock opposite the cliff. Then shopkeeper Qian went up first. The others wrapped their clothes tightly and hid behind the rock on this side.

These bats seem to have an instinct to attack people trying to cross this underground cliff. As soon as shopkeeper Qian climbed half way, the black bats on his head rushed down. Shopkeeper Qian immediately fastened the safety rope, bypassed the rope with his arms and covered his head and face. Even if his body didn't use nano clothes and bulletproof vests, these little things couldn't bite him, What's more, he wrapped himself so tightly.

As most of the bats have flown down from the top of the cave, a large black area circled around shopkeeper Qian, and some have jumped on him and began to bite. We gathered all the flash bombs, each holding two and biting off the pull ring, waiting for Quinn's command.

"1, 2, throw." when Quinn counted 1, we released our thumb and threw it out after the fuse burned for two seconds. For a moment, the sky burst out a lot of strong white light. We lowered our heads and closed our eyes. We could feel the strong flash, which seemed to pierce our eyelids, let alone the bats who lived in the dark for a long time. They were immediately confused by the flash, hit each other and fell down, and some beat their wings desperately and flew away hastily along the small hole in their heads.

"We have to hurry over. They're just frightened and will come back soon." brother donkey shouted at everyone, but everyone ignored him, because he was more or less familiar with his style. If he didn't shout at this voice, he wouldn't be brother donkey.

After the whole team passed the cliff in the shortest time, brother donkey observed the platform and stone wall on this side of the cliff for a long time and said to us, "it must be the right place. This is already sedimentary rock. Moving forward is likely to be the goal."

Old black looked brightly into the connecting cave of the platform and laughed: "literati, you know? You look inside..."

We all followed his line of sight, but we couldn't see anything clearly. Sanmei said "eh?" in surprise. We remembered that Lao Hei could see things in the dark, so we immediately turned the flashlight. I saw a stone tablet more than two meters high, standing in the recess of the stone wall on the right side of a cave. Because it is well connected, we should look carefully.

Of course, this kind of thing is brother donkey's strong point. He ran over with excitement on his face. After reading it carefully up and down, he said to us, "there are two news, one good and one bad. Which do you want to listen to first?"

Lao Hei "brushed" out the unparalleled knife, and "Dang" cut off the tip of a stalagmite next to him. In a gloomy tone, he said, "pick one that looks good to your eye.".

The donkey paused for a moment and said without delay: "The good news is that we have touched the periphery of the super pit. The bad news is that according to the statement on this stone tablet, the place is terrible. I don't know how to pronounce these pictographs, but in short, it means very scary. If mortals want to get there, they have to experience four disasters, namely, bats, sharp blades, darkness and blood loss."

"We have just experienced bats. What are the differences between sharp blade, darkness and blood loss?" asked a mercenary. No one spoke, because no one knew the answer.

If you move forward without knowing anything, the risk factor will increase greatly. Thinking of this, I said to Quinn: "Po and Ares are together. I don't know if they know anything about here. If you contact them, you may be able to find out something."

Quinn glanced at Lao Hei, shook his head and said, "we've spent almost a day recently. There's no signal here. It takes us about the same time to send people out. The opponent has been ahead of us too much. Let's be hard." Quinn said and motioned everyone to move on.

At this time, the airborne soldier named Sea Eagle signaled Quinn to stop first. He pointed to his backpack and said, "head, I think I can contact that man."

"Use drones? Our drones can't dive?" Quinn asked suspiciously.

"I brought the smallest VTOL. I think I can find the way out along those bat caves." The sea eagle took out four plate-shaped propellers and the main body of the UAV from its backpack, assembled them several times, took out the remote control and debugged it several times, and the camera on it turned around. The sea eagle removed a small pistol and replaced it with a tactical flashlight. It also programmed the communication equipment on the UAV, so that once the satellite signal is connected, it will automatically send a message to ah Bao's communicator.

Next, we watched the eagle control the machine and flew up in a buzzing sound. After moving back and forth twice, the eagle chose the widest hole to fly the UAV in. The holes where bats flew in and out were very winding. There was a loss of signal in the UAV. We had to send two brothers with flexible hands and feet to climb up and nail a signal intensifier at the hole, This restored control of the UAV.

After tossing about for more than an hour, he finally sent the information for help to Po. Originally, he thought he could reply at most. Unexpectedly, half an hour later, with the change of light and shadow in the hole, he actually came in person.

"Why are you here? You killed kunba?" I immediately rushed up and asked.

"No, that guy is too cunning, but he should not be a big deal if he was hurt by me. Ares, they were very excited when they saw your message. Some people cheered, others shouted, and several people even knelt on the ground and cried." Po replied.

"Cry? What do you mean? The blood dragon won't cry too." I outlined in my mind what the blood dragon would look like when it cried.

"Did he arrive, but he was also very excited. He looked up at the sky and said something. We finally found him."

"What's the meaning of being found by them? Is it good that we found it?" I cried discontentedly.

"Even if you find it, it's also the remains of other people's ancestors. Don't worry about it so much. They asked me to bring you a message. These four lines of defense are used to prevent the holy land from being peeped. Although the specific crack methods have been lost in the Nazi capture and pursuit, they still know the contents of the line of defense, and they will come later." Po drew several concentric circles on the ground, pointed to the pattern and continued to tell us.

"The most central, you all know, is the territory of the God of death. According to Ares, it's called Xibalba. You passed the first of the four peripheral checkpoints. Maybe it's the only one you can pass. The next three, I'll take you there." Po confidently pointed to the depths of the hole and said to us
