"Do you have a way to find the sewer pipes or something in the underground prison?" Luo Zheng asked with a serious face.

"I tried it, but I didn't find it." Shadow smiled helplessly.

"Isn't there a river ten kilometers away here? Will it be directly connected to the river? There are so many people in the underground prison, how can domestic sewage be discharged? I don't believe they don't have underground pipelines." Luo Zheng said seriously, his face as solemn as iron, and he exudes anger.

"A river channel ten kilometers away?" Shadow's eyes lit up, and she immediately became scheming, and she said, "Otherwise, I'll go and look for it immediately. Without further ado, since there are spies, our situation may have been exposed and we must be as soon as possible."

"Go together, forget it here." Luo Zheng said. He originally wanted to tie two people up and pretend to be the other party and sneak into the underground prison. Since the defense is so tight and there is smart scanning, he simply gave up this plan and signaled the shadow to take action. The two of them quickly evacuated the forest and walked towards the entrance of the village.

When they arrived at the entrance of the village, Luo Zheng took out the car key and unlocked it. The two got into the car and quickly left. Shadow guided the way. Half an hour later, the two came to the river near the river and parked the car. After getting off the car, they came to the river bank. The river water was quite clear, and the bank was full of street lights. Someone was walking by the river. Luo Zheng and Shadow exchanged glances, walked up and down, and carefully inspected the river water.

It is easy to identify whether there is a sewage outlet. The water quality is completely different. After half an hour, Shadow called and said that it was discovered that an abnormality was found. Luo Zheng quickly returned and after merging with Shadow, he found that there was a drainage canal on the bank of the river connecting the river channel. The river water was polluted, and the drainage canal was enough to accommodate a person in, with sewage flowing inside.

Luo Zheng looked around. It was flat and could not see the source of the drainage channel. The lack of source could explain the problem. Shadow whispered: "Such a large drainage channel is not used for ordinary community houses. There is no factory around. It is more likely to connect to the underground prison. I'll go in and take a look."

"No, this drainage channel may not have other outlets or ventilation openings. If it is a special culvert with no air inside, you will die if you go in. Let's take a look. If you want to go, you have to bring equipment." Luo Zheng quickly grabbed the shadow and reminded.

Shadow was eager to save people, ignored this detail, and heard Luo Zheng's analysis and looked around and pondered. After a while, Shadow said, "Let's go, look around."

The two of them acted separately and looked around the drainage channel. After half an hour passed, they did not see any other connection ports. They were dedicated culverts. After recording the address, they quickly returned to the car and headed towards the embassy. Along the way, the shadow remained silent, and Luo Zheng didn't say much, so he drove seriously.

Not long after, Shadow suddenly said: "The possibility of a drainage channel being a culvert is high. The culvert cannot be repaired. Once it is blocked, it cannot be used. Therefore, there must be something on the other end of the underground prison to block the drainage channel. First, it can filter debris and only allow sewage to remain. Second, it is useless to touch it. What can you do?"

"The underground prison is so tightly defended. I guess the drainage channel has motion sensors and infrared detectors. On the one hand, it is to prevent sneak attacks from being attacked, and on the other hand, it is really difficult to deal with. But if you really connect to the underground prison, there are always ways. Don't worry, give me some time, there will definitely be no problem." Luo Zheng said confidently.

"Okay, I believe in you." After Shadow and Luo Zheng had been in contact for a while, they knew that Luo Zheng was a planner. They were meticulous, thoughtful, and bolder. They could do anything. They had more expectations and confidence in rescuing Ye Laixiang.

Everyone returned to the embassy without knowing it. When they came to the room, Luo Zheng called everyone and told them the situation. Everyone was very happy and finally found something. Lan Xue looked at Luo Zheng, smiled knowingly, and said, "Are you planning to attack with poisonous smoke again?"

"Poisonous smoke? What does it mean?" Shadow asked in surprise.

"Poisonous smoke is poisonous smoke? If a handful of poisonous smoke goes down, all the people inside will be knocked down." Ghost Hand explained, and when the primeval forest appeared in his mind, everyone was smoky at the underground base, and couldn't help but laugh.

Shadow was a little confused and looked at Lan Xue. Lan Xue explained briefly. Shadow's eyes lit up and said, "This trick is good. Even if the connection is blocked, we can still smoke them with poisonous smoke. However, with the poisonous smoke, the prison will definitely call the police and take the people out. There are hundreds of meters of guards there. In addition, the troops have been added just now, so we still can't save people. Ghost, do you have a trick?"

"Yes." Luo Zheng smiled confidently. Seeing everyone looking over in confusion, Luo Zheng said: "It's very simple. Use poisonous smoke to drain the drain. Put on a hair dryer and a cutting machine. The hair dryer blows the poisonous smoke in. The cutting machine cuts the sealed area so that everyone can enter. As for the guards outside, what else can they do under a fire?"

"Yes, why didn't I expect it?" Snow Leopard shouted in surprise.

"I didn't expect it, could you think of it? No wonder the ghost asked us to prepare the burning object." Ghost Hand said in agreement.

Luo Zheng saw Lan Xue looking at him with a smile, and smiled awkwardly, explaining: "We should do something tonight. When the fire is together, the Guards will definitely evacuate. The situation is unclear. In addition, it is night, the underground prison will definitely not dare to transfer. For safety reasons, the ground passage will be blocked. In this way, the underground and the ground will be cut off. In order to ensure that, it is best to cut off the Guards and diplomatic ties and then release poisonous smoke."

"Okay, that's it. Brother, your plan is not simple." Shadow smiled happily, and calculated in his mind, saying affirmatively: "The success rate of this plan is 60%. Who would have thought that we would attack on both sides, and the guards on the ground would be handed over to me for fire prevention, communication damage, etc. I'm in progress, so I'll ask you underground. Without further ado, I'll go and investigate the drainage channel now."

Shadow was eager to save people. With a plan, he was energetic and could not wait to act immediately. Everyone smiled in understanding and looked at Luo Zheng. Luo Zheng thought for a while and said, "Okay, we will divide the troops into two groups. Shadow and I will investigate the drainage channel. You can find a way to prepare as much combustion as possible and get some time bombs. The power does not need to be too great, so that the shadow can detonate and ignite the fire."

"Don't worry, it's better to prepare for RPG. I'll go to a night attack base. When the rocket launcher explodes, the chaos will happen. The Guards will definitely think that someone is attacking and sending troops to pursue it. I didn't expect your movements. The bigger the movement, the better. If there is an armed helicopter," said the shadow, with murderous aura. At this moment, the passionate side of the soldier was revealed.
