The strongest soldier

After returning to the camp, Shadow found Shi Qian and asked about it. He was relieved when he learned that everything was normal and no enemy launched a sneak attack. He immediately introduced Lei Jian to Shi Qian and asked about Lei Jian's situation. He learned that He was hit in the head during the battle and fell down the hillside. Shadow saw a sunken crater on the Thunder Sword helmet, and he was very lucky. Fortunately, he was wearing bulletproof armor and a helmet, otherwise he would have been dead.

Lei Jian also had a look of fear on his face, but he was overjoyed. Shadow comforted Lei Jian, let Lei Jian go aside to rest, and immediately reported the situation to Luo Zheng.

In the Duanpo Cave, Luo Zheng, who was deducing the next counterattack tactics with the think tank, secretly breathed a sigh of relief when he heard that there were survivors. He told Shadow to continue to guard the front line and not to take the initiative. After continuing to discuss with the think tank, he looked at Cao Xi and whispered Asked: "How long will it take you to find the underground river?"

"It's hard to say. I've paid attention to the surrounding terrain before. There are dry wastelands everywhere with no plants. It's hard to judge. It may take me three days, or two days at the fastest." Cao Xi said with some embarrassment.

It is indeed difficult to find underground rivers in the barren and barren mountains. Three days is already considered fast. Luo Zheng nodded in understanding and frowned in thought. There is not much time left for everyone. Three days will definitely not work. Two days will be enough. No, something will happen as time goes by. The wise man suddenly said: "I have an idea."

"What?" Luo Zheng asked in surprise, his eyes a little more expectant.

"Don't worry, show me your drawings." The think tank said in a deep voice.

Luo Zheng was startled, then realized what he was doing and took out his phone to open a drawing. The drawing was drawn by Xuelian based on satellite scanning. The satellite found that there are many heat sources underground. It was drawn based on the location distribution of the heat sources and the characteristics of the terrain. It can be said that this It is a map of the enemy's troop deployment. Although it is not necessarily accurate, it is roughly equivalent.

The think tank carefully analyzed the drawings, frowning, and fell into deep thought. Luo Zheng did not interrupt, and also thought about countermeasures. After a while, the think tank suddenly raised his brows, with a bit of joy on his face, and looked at Luo Zheng. Zheng said: "Look, the entire underground base is distributed from east to west. The long passage you mentioned also runs from east to west. It should be this one." He pointed to a line on the screen.

"Yes, it should be." Luo Zheng replied in a low voice with certainty.

"The prison is next to the passage. You have been here before. Am I right?" The think tank pointed to another location and continued. Seeing Luo Zheng nodding in the affirmative, he couldn't help but smile. He relaxed and continued: "OK After these few positions, my speculation can basically be established.”

"How?" Luo Zheng asked curiously.

"It's very simple, come and see." The think tank zoomed the entire map and revealed the overall overview and said: "The entire underground base runs from east to west and is more than three kilometers long and more than one kilometer wide. Such a long underground fortification is only connected by a long passage. , there are more than 2,000 people underground, how to solve the problem of domestic water supply? How to solve the problem of sewage discharge?"

"You mean the underground fortifications were built along the underground river?" Luo Zheng was startled, suddenly realized, and looked at the think tank in surprise and asked.

"That's right, only in this way can the people below not run around with water. Just dig a well anywhere and lead to the underground river to get water. I was in prison for a while, and the prison door was the only connecting passage. There was no Seeing people at both ends carrying water, there is only one explanation, people at both ends can get water." The wise man said seriously, his eyes shining with the luster of wisdom.

When Luo Zheng heard this, he was overjoyed and smiled. As expected of the veteran club's think tank, he could find problems through subtle details. At this time, the think tank continued: "The trend of the underground river is the same as that of the underground fortifications. The ground of the prison where I am is wet, which shows that the underground river is wet. The river may be under the prison, and there is a hole for the prisoners' excrement to go down and then flush. At that time, we thought it was a pit that had been dug long ago, but now it seems that it should be an underground river."

"Doesn't that mean that domestic water and sewage are together?" Tie Diao asked in surprise.

"No, they must have considered this issue when they built it. They should have dug another branch next to the underground river as a sewage canal, and then diverted water into it for flushing. The distance is too far, the project is too big, and it is not suitable. What we need to do is Two points, first, make sure that is upstream, and second, make sure the specific location." The think tank said and looked at Cao Xi.

Cao Xi took the map and studied it carefully. He turned on his mobile phone and called up a holographic terrain map. After a while, he showed a relaxed smile and said: "In front of the ruins is a river, running from east to west, with the upper reaches in the west and the surrounding areas." Looking at the overall terrain, the west is higher, and the upstream of the underground river is more likely to be in the west. Perhaps the so-called underground river and the surface river are one, but because of crustal movement or other reasons, there is an extra crack in the underground, and the river water pours in. The cracks became underground rivers.”

"You mean that as long as you find the place where the river water pours in, you can find the entrance to the underground river?" Luo Zheng asked in surprise.

"Yes, I'm sure of this. The terrain here is high, the mountains are steep, the land is barren, and the entire mountain range is severely weathered. It doesn't look like there is a water source at all. Therefore, there is a greater possibility of underground cracks forming after crustal movement. The cracks It happens to be connected to the river, and the river water pours into it. I estimate that this crack is very big and deep, and maybe it can be used." Cao Xi said with confidence.

"Yes." Everyone was experienced in fighting. Their eyes lit up and they all smiled.

"The underground river is not conducive to human traffic. It would be easier if there are cracks. We can penetrate directly into the enemy through the cracks and catch the enemy by surprise." The think tank added in surprise, looking at Luo Zheng with eyes full of fighting spirit. His emotions also became high, and he clenched his fists with an expression of hope for revenge.

After being imprisoned for more than three years, no one can let go of this hatred, not to mention that the other party is still a mortal enemy. The think tank is always thinking about revenge. The opportunity is right in front of him. The think tank is not calm anymore. Luo Zheng is also a little excited. If it is really like Cao Fortunately, we can definitely capture the base in one fell swoop.

The closer he was to success, the calmer Luo Zheng became. Especially after the dark night last time, Luo Zheng realized that his tactics were sufficient for offense but insufficient for defense. Faced with temptation, Luo Zheng did not act as impulsive as usual, but instead thought over and over again. Get up and think about what to do if you fail?

"What's wrong? Is there a problem?" Seeing Luo Zheng's silence, the think tank asked curiously.

"Are you sure it is a gap formed by the movement of the earth's crust, not an impassable underground river?" Tie Diao looked at Cao Xi worriedly and asked. This judgment is too important. If you make a mistake, you will suffer heavy losses.

Cao Xi corrected: "Underground rivers are basically formed by the movement of the earth's crust, and they are all accessible. The underground rivers in the plains are different from those in the mountainous areas. The underground rivers in the mountainous areas are also different. They need to be treated in detail. I suggest you go and take a look."
