"Or, return from the original road, don't you know directional blasting? If you have a grenade, blow it up! "

As far away as the Caroline Islands, Lou Zhao was still bargaining with Xu Qing. Xu Qing said, "it's covered bombing outside. Such a big pit has been filled. We must find another way out. Or we can go into the water together. Anyway, this place will not be long."

Lou Zhao said, "if you had said that earlier, where would you have been pestering for so long?"

Xu Qing was very angry and said, "it's hard for a man to say a word. How can you talk like farting?"

Lou Zhao's face was neither red nor white. He said, "I'm not a big man, I'm a little girl!"

Xu Qinglang looked up at the glowing fluorite, checked the number of cold flames, looked at the little girl and asked, "how long can you hold your breath in the water?"

Little girl said: "can hold for five minutes."

Xu Qing nodded and said, "yes, it's much better than the average level of the Marine Corps. I'll be in the water later. You can hold my neck for seven minutes with your eyes closed

"Yes

Xu Qinggu talked about the others, yin and Yang strange way: "people's little girls are so fierce, some people grind and talk, delay many things, if the battlefield, I will not shoot her."

Lou Zhao's face is still not red or white. She completely forgets what she said before and what she heard from Xu Qing. Moreover, she feels that she is right. Her personal starting point is different. She never regards this place as a battlefield, but only regards Xu Qing as her younger brother who needs his protection. After listening to Xu Qing's words, she only feels that Xu Qing is a child and angry.

Xu Qing looks up at the fluorite above his head, goes to the wall and climbs up cleanly. Now they are underground and at sea level. They need to dive and have no oxygen equipment. Looking at the distance from sea level, they need to climb and have no climbing equipment. They all depend on their strength.

Xu Qing is not afraid, because what he trained most at the beginning was to survive in the wild without equipment. When he was in the cold war with Lou Zhao, he had calmed down. Finding a way out underground should be similar to finding a way out in the wild. The difficulty is that he can't distinguish the direction and there is no light. He never doubted whether it was a sealed place that couldn't get out at all, because when he entered the cave, he lit a large kerosene fire. For such a long time, there was no sign of dyspnea, indicating that the pool was constantly releasing oxygen, and there must be an outlet.

Xu Qing quickly climbed to the top and reached out to touch fluorite. Straight up and down, where there was no help, Xu Qing pulled out two sabres and stabbed into fluorite obliquely. The hardness of this Sabre was not weak, which could not be compared with that of manganese steel sabres. Xu Qing used this method to hang up to the top of the pool, holding the handle in one hand, chiseling a hole with the sabre in the other hand, and then He said to the people below, "all lie down against the wall and hold their heads."

At this time, Lou Zhao was obedient and held the little girl in his arms. Xu Qing put thunder in her hand. As soon as she opened the ring, Xu Qing jumped down from above and used a little real Qi. Just when she fell to the ground, it exploded, Large pieces of fluorite fall into the water, and the stars make the cave bright as day, and the pool is also very bright. At a glance, you can see everything in the water clearly.

He packed a lot of large fluorite in the spare space of his backpack. Lou Zhao was puzzled and said, "can you float something with such a high density on your back?"

Xu Qing said with a smile: "long hair, short knowledge, do you know the density?"

After all, Xu Qing didn't know what button on the military backpack he pulled, but suddenly the air around him inflated, and the volume became huge. This kind of air inflation function was snatched from sang Fuguo's soldiers. This kind of air inflation function is to have more survival opportunities when parachuting into the water. The Sixth Army is still developing, but sang Fuguo's technology is quite mature.

Xu Qing was ready and ordered, "get in the water!"

He was the first to enter the pool, pushing his backpack with both hands, swinging his legs forward, and everyone followed. Humans are afraid of the dark, and Xu Qing is also afraid of it, so he made the decision to make the water bright, at least to support them to go a long way forward, and to make their eyes better adapt to the next darkness.

Xu Qing never thought that this corridor would be so long, and he didn't know if it was the reason why he seldom saw the underwater corridor. He felt that the cave was so ferocious and terrifying. Five minutes later, Xu Qing looked back at the little girl hanging around her neck. Her breathing was ok, but if she couldn't see the waterway at the end, it wasn't necessarily 20 minutes If you can swim out, you and Lou Zhaolou have entered the internal breathing, and the little girl is already holding her breath. At this level, the future is definitely a sign of the Marine Corps.

Xu Qinggang is going to have a look at the limit of the girl. Suddenly he finds something at the bottom. Xu Qing claps the girl's hand back and signals her to release herself. Xu Qing gives the backpack to Lou Zhao and sinks down. He touches an oxygen tank, which is the most advanced ventilator in the world so far. Someone takes off the oxygen bottle here, and the oxygen is still leaking. Xu Qinggang is very happy Qing quickly closed the door and saw the bloodstain under the oxygen bottle. In the water, the bloodstain would not solidify. However, judging from the degree of dispersion, there were also rags nearby. This man, who had just been dragged away, didn't even have a piece of meat. Xu Qing's face became bad. There was a food chain in this place, but he was comforted that he was about to get to the exit. It won't take twenty minutes.Gradually forward, the weaker the light, and then back, the visibility tends to zero, Xu Qing sent everyone a piece of fluorite, the only thing you can see is the halo in each other's hands.

Moreover, the corridor is becoming narrower and narrower. Xu Qing originally planned to give the backpack air bag to the little girl to breathe. Now with the oxygen machine, there is no problem.

However, Xu Qing soon encountered a new problem. He accidentally touched the bottom. The bottom was not hard material, but suction sand. Xu Qing was sucked down half of his body at once. However, Xu Qing reacted too quickly and quickly released his true Qi. There were many bubbles around him, which made his body less dense and quickly floated up. This action soon stirred up a piece of mud Sha, where the hell is this? Xu Qingyin scolded and looked back quickly. Fortunately, Lou Zhao and Lou Laosi, who have been paying close attention to Xu Qing, saw the problem Xu Qing encountered and were not entangled by this problem.

Xu Qing thought that he had to leave the place quickly. Suddenly, his feet were tight. He thought of the strange fish he had met. He pulled out his saber and wanted to cut off the things that caught his ankle. But he didn't think it was a hand.

Xu Qing's scalp is numb. If he meets a water ghost, his world outlook will be really refreshed. But almost in an instant, he calms down, lowers his head, grabs the hand, and tramples on the stone wall. His body rushes forward and pulls the man out of the mud. Xu Qing is relieved that he is a man, not a water ghost. But he can't do it any more. His mouth and nose are full of mud. Give him a ventilator and he can't breathe.

Xu Qing doesn't know his identity, but he won't die without help. Xu Qing slashes his hand on his neck and makes him unconscious. His body enters the self-protection system, and he can persist for a while.

Xu Qing drags this man and swims deeper step by step. Lou Zhao and others behind him can only see Xu Qing's shadow and swim forward.

Finally, in the darkness, a man-made cave appeared in front of him. Xu Qing pushed aside the sand and went through the cave. Although it was still dark, he also had a feeling of sudden brightness.

Xu Qing waited for them to come out of the cave, float up together, and finally came out. It was an irregular, large cave extending in all directions. After experiencing the dark moment of almost zero light source at the bottom of the water, he could see almost anything. Xu Qing first observed the small holes around him. No matter which one he looked at, Xu Qing felt extremely ferocious, like a wild animal with long hair Big mouth, waiting for himself to go in, Xu Qing calm face, light way: "elder sister, fourth brother, you alert, I first save this person..."
