Arnold said: "This tunnel is very strong. We can stuff grenades under the wall and detonate them from the bottom. The one that is hit the most is the wall, and there should be no collapse." He knew much more about weapons and ammunition than others, and he was quite confident in this regard. After some observation, he found that there was a triangle gap below the wall, and the grenades should be stuffed into it and detonated from below.

Sparrow said: "Even if the explosion goes well, we exploded the wall. What is waiting for us behind us?"

Arnold was obviously asked by the sparrow. He thought that there should be water behind the wall. Once they exploded the wall, the water blocked on the opposite side would surge and swallow them all. Thinking of this layer, Arnold couldn't help but retreat.

The blind man sighed with regret and said, "It seems that the secret treasure should be on the other side of this wall, so we have no chance to enter." It is more important than the secret treasure. The blind man can live for Luo Liehe, but he is not greedy for money and can spare his life for the secret treasure.

Luo Lie said: "It's not that there is no chance. It's only more than 100 meters away from the exit. After detonation, even if it is washed out by water, I can resist this distance." He was quite confident in his ability to hold back his breath in the water.

The rest of the people understood what he meant. The sparrow shook his head and said, "No, you can't take risks!" The dangerous scene just now still shocked her, and she didn't want Luo Lie to take risks again.

Luo Lie smiled and said, "I am a man who is naturally curious. If I don't understand this, I'm afraid I will be unable to sleep or eat. You go outside and wait, I'm responsible for blasting. If everything goes well and it won't take too long, I will be sent to the ditch outside. You are ready to fish me out of the water."

Arnold said: "It's not impossible." He handed one of the lifebuoys to Luo Lie in case of emergency.

The sparrow wanted to stop it, Luo Lie patted her on the shoulder and said, "Don't worry, we have all come here, we can't give up halfway. I'm very good at water. The flood discharge channel just now was several times longer than this one. I'm fine, you don't have to worry."

The blind man didn't say anything, and came to Arnold to ask for another lifebuoy. Luo Lie knew that he wanted to advance and retreat with him, and was secretly moved in his heart, but he didn't want the blind man to do this, and whispered: "Blind man, you and Arnold are responsible for protecting the sparrows, and I can handle it alone."

The blind man said, "It is always better to have someone to take care of him. Don't forget that I taught you swimming. Besides, it's so dark here, so people have to guide you."

Seeing that he insisted, Luo Lie could only nod. After Arnold taught the explosion method to the two of them, he protected the sparrow and retreated first. Luo Lie stuffed the tied grenade into the depression at the base of the wall. The triangular depression could actually stuff eight grenades into the depression.

The two of them retreated to a safe distance. The blind man changed his pistol and aimed at the bundle of grenades. Luo Lie couldn't help but feel nervous at this time. He held his breath for fear of disturbing the blind man's shooting. The blind man glanced for a while, and his hand holding the gun fell down again, shook it back and forth a few times, and breathed a sigh of relief.

"Don't be nervous!" Luo Lie cheered him up.

"It would be great if Lu Weilin was there." The blind man couldn't help but think of the sharpshooter at this time. He didn't have much confidence in his marksmanship.

Luo Lie encouraged him: "If you can't do one shot, just two shots. We have time."

Arnold's voice suddenly came from outside: "Blind, can you do it? If not, I'll go in and change you!"

The blind man spat and said loudly, "Golden Retriever, I'm the most annoying to others to provoke me. I'm better than you if I close my eyes." He raised his pistol and aimed at the front and shot a shot. After the crisp gunshot, he had no response. The blind man fired a few more shots, but the gun fell into nothing. Arnold's loud ridicule came from outside. The guy couldn't help but feel a little anxious. There was only the last bullet left in the gun, and he cursed angrily: "Golden Retriever, I'll fuck you!" It's strange that every time he scolded Arnold, the blind man felt that he was full of magical power.

Bang! The bullets were shot out from the gun chamber, and this time it actually hit the bundle of grenades accurately. Bang! The eight grenades were triggered almost at the same time. The explosion caused the entire underground passage to shake violently. Luo Lie dragged the blind man and yelled and fell down. His voice was covered by the sound waves caused by the explosion, and even he could not hear his own voice.

The two of them lay on the ground and covered their heads with their hands. They felt the gravel and dust falling on their bodies. Both of them were shocked and drowsy. They thought they would be surrounded by the flood that was surging, but after waiting for a long time, no water surged to them.

There came outside, the sound of Sparrow and Arnold's concern. Luo Lie was still a little tinnitus. His hearing failed to fully recover for a short period of time. He shouted: "We are fine, don't come in for the time being."

The blind man coughed violently by the dust. He got up from the ground and covered his body with a layer of sand and stones. When he looked at Luo Lie, he was in a mess. Thinking about his current appearance, he must be not much better. The two of them supported each other and looked at the explosion.

Walk around.

Luo Lie thought the explosion was not successful, but when he came near the front, he realized that the wall had successfully collapsed, and a big hole was revealed above it, but the wall was not as water as they had expected.

When the blind man saw that the stone wall was successfully exploded, he couldn't help but raise his hands and cheer loudly.

At this time, the hearing of the two began to gradually return to normal. Sparrow and Arnold had already walked in with great difficulty. Although they were outside, they had guessed the situation inside from all kinds of signs.

Luo Lie was the first to climb up the gap, and then reached out to pull his companions over one by one. There were many white bones scattered on the ground here, but these white bones were scattered, unlike the entire bones outside. It should be that the air waves caused by the explosion just now shattered the bones. The blind man found a bronze candlestick on the ground, and there were two candles scattered on the ground next to them.

Luo Lie walked over and lighted the candle, raised the candlestick to illuminate the dark underground world, but saw a circular reservoir not far ahead of them. The diameter of the pool was about ten meters. It could be seen that the pool was extremely deep and the water surface was about half a meter away from the edge of the pool.

Several people searched around here. Except for the flood discharge channel they just entered, there was no other channel connected to the outside world. Has this place reached its end?

Dozens of skeletons lie in the edge of the pool. These skeletons were not seriously impacted because they were far away from the explosion point and were basically kept intact. It can be seen that the skeletons were all there, which was completely different from the outside. The skeletons here should not be beheaded.

The blind man found a wooden stick nearly three meters long from somewhere and inserted it into the pool. His hands were buried in the water, but he still didn't reach the bottom of the pool. The blind man sighed: "It's so deep."

Arnold carried a rope with him. He picked a stone, tied it with it, sank into the water, put it for about ten meters and didn't see the bottom. He turned to the blind man and said, "It's really deep."

The blind man said, "I have a premonition..." Before he finished speaking, he was interrupted by the sparrow: "Don't say it!" In fact, even if the blind man didn't say it, she knew what the blind man wanted to say.

The blind man had a premonition that the secret was hidden in this pool. In fact, Luo Lie also had the same idea as him. The reason why the sparrow stopped the blind man from saying it was that his real intention was that he did not want Luo Lie to take risks. She knew that Luo Lie was a person who would not give up easily, and she had even concluded that Luo Lie would take risks alone.

Luo Lie had already arrived at the pool and reached out to find out the water temperature. The water temperature was a little cool, but it was still within the range that his body could bear. Luo Lie said, "I'll go down and take a look." This was actually what the sparrow said.

The sparrow didn't say anything. She found that she had never cared about someone as much as she is now, and she was confused. It was precisely because of her concern for Luo Lie that her temperament changed. She became hesitant, worried about gains and losses, and even she didn't know herself anymore.

Luo Lie had already started to take off his coat, revealing the black water inside. Fortunately, they were ready before, otherwise they might not be able to withstand the low temperature when they went directly into the water.

The blind man came over and said, "Luo Lie, why not go down there, I'm heavier than you, and dives will definitely be faster than you."

Luo Lie laughed. Although the blind man is good at water, he has not learned diving specifically. He is too much stronger than him at this point. What's more, after he learned how to breathe and breathe with Wu Jie, he felt that he had improved a lot in holding his breath compared to the past. He took this opportunity to challenge the limit.

The blind man said, "I am better than you, and I can see things in the dark."

Luo Lie looked at this friend who could entrust his life and felt moved. He whispered: "Diver is different from swimming. Although you can see things in the dark, you are like a blind person underwater. It is mainly based on feelings." He wrapped the rope around his right foot: "I'll go down and see. I'll hold my breath underwater for ten minutes. You can help me read the table. Within ten minutes, I will definitely return."

Arnold rolled up his neck, revealing his military watch with excellent waterproof performance, and untied it from his wrist and handed it to Luo Lie: "Wear it, don't forget the time."

Luo Lie nodded, took his watch and put it on.

The sparrow who had not spoken for a long time finally spoke: "Seven minutes, we will only give you seven minutes. If you don't come back for seven minutes, we will drag you up together."
