The strongest soldier

In the huge valley with towering peaks on all sides, the warm sunshine is completely blocked by the towering peaks. The cold wind pours in from the only entrance and exit of the valley. After entering the valley, it becomes messy and makes a buzzing echo. The spring water at the foot of the mountain gurgles. Gu surged and flowed slowly along the edge of the cliff. Luo Zheng looked at Cao Xi who was walking in a hurry. Knowing that he had come to a conclusion, he couldn't help but go up to him.

"Boss." Cao Xi said excitedly.

"Tell me, what are your conclusions and basis?" Luo Zheng asked.

"The conclusion is that this place can be used as a base, based on three points." Cao Xi said happily: "First point, this place is big enough, the air can pour in from the canyon, disperse and rise into the sky, and the enemy cannot use poisonous smoke from the top of the mountain. As for the entrance and exit of the canyon, even if you use poisonous smoke or the like to attack, it will disperse immediately after entering the valley and rise high into the sky, and will not enter the middle or bottom of the valley at all."

"Wait a minute." Luo Zheng said in surprise: "You mean the poisonous smoke will rise into the sky after being released from the canyon?"

Poison smoke attack is Shi Qian's specialty, but there is no guarantee that the enemy will not use the same method. If there is enough poison smoke, wouldn't it be easy to capture the entire valley? Luo Zheng was worried about this, but he didn't expect Cao Xi to say that the poisonous smoke couldn't get in? This made Luo Zheng very curious.

"Of course." Cao Xi said confidently, and looked at Shi Qian. Shi Qian was looking doubtfully at the entrance and exit of the canyon, which was still more than a thousand meters away from him. He couldn't help but think deeply, but Cao Xi continued: "Don't believe us. You can go to the front and have a look, I’m sure it’ll be fine.”

"Let's go." Luo Zheng said in a deep voice. This issue is very important. It's impossible not to understand it clearly.

Everyone hurried forward and came to near the entrance and exit of the canyon. Cao Xi smiled confidently and said: "Boss, watch it." He squatted down and grabbed a pile of dust and threw it into the air. The dirt particles fell down, but the dust But he died in the sky with the wind, clearly visible.

Luo Zheng was overjoyed to see this scene and looked at Shi Qian. Shi Qian nodded knowingly and said, "Indeed, the current wind is strong enough to blow the poisonous smoke into the valley. If the wind is smaller, it may not be able to blow the poisonous smoke in. This conclusion Believable.”

"More than that, don't worry even if the wind is lighter." Cao Xi said confidently. Seeing everyone looking at him curiously, he explained: "When the wind blows into the valley, it will reverberate, just like the tide rushing onto the beach, because There is no way to go, and then we roll back. The wind here is the same. No matter how strong the wind is, this phenomenon will occur. In addition, this place is big enough. Our base will only need to be lowered to the middle or bottom of the valley. I propose At the bottom, noxious smoke can blow in at all."

"It's interesting. Come on, let's go back to the bottom and have a look." Luo Zheng said with a smile.

Everyone hurriedly returned to the bottom of the valley. It was obvious that the wind was much lighter, and it was indeed in the opposite direction. We were all smart people, and we couldn't have imagined the benefits. Luo Zheng looked at Cao Xi happily and said, "As expected of an expert in geography, You are very observant, tell me your other evidence."

"Thank you for the compliment, boss." Cao Xi smiled and said: "From a geographical point of view, three points are very important. One is wind, two is water and three is soil. The wind is beneficial to us. You can rest assured about this. There is also water. I took a closer look. , the mountain springs here can also double the water output, groundwater, water veins come along the mountains, very irregular, there is no need to worry about being cut off, by then the mountain springs will be enough to meet the daily needs of thousands of people. "

"Wait a minute, what is the trend of the water veins you are talking about?" Luo Zheng interrupted and asked.

"I have observed the water veins here. They come along the mountains. The mountains here are steep and winding. Even if the enemy sees the direction of the water, there is nothing they can do unless the entire mountain is leveled. The mountains here are towering. Even if It's impossible to level it with missiles, so don't worry," Cao Xi explained.

Luo Zheng didn't know much about these things, but seeing Cao Xi's confidence, he believed it, nodded and said, "Very good, let's talk about it, what's going on?"

"Soil is soil quality. Soil can be divided into living soil and dead soil. For example, in places with severe desertification, most of it has turned into dead soil. It will run away when the wind blows. The soil is loose and not conducive to human habitation. The soil here is mainly shale. Mainly, mixed with bluestone and granite, it is very hard and cannot collapse the cliff to bury the valley. Even if missiles attack, the cliff here will not collapse in large areas." Cao Xi explained.

Luo Zheng looked at the exposed rocks on the surrounding cliffs. The dark brown rocks looked very hard, with water vapor still on them, and some green grass roots growing in the cracks. He couldn't help but smile and said: "The three points you mentioned are very good. Do you have anything to add?”

"One thing is snow." Cao Xi pointed to the top of the mountain and said: "This place will definitely have heavy snowfall in winter, and the valley will be buried by heavy snow. This is the only shortcoming. If we put our residence inside the mountain, then No more problems.”

"You mean digging into the mountains and living there?" Shi Qian asked in surprise. Seeing Cao Xi nodding in the affirmative, he thought for a while, looked at the pensive Luo Zheng and said, "This is a good idea, hiding us in the mountains. , the enemy cannot see it, so it will be difficult to make a sneak attack. However, the soil here is hard and it is not easy to dig. What we lack most is time, boss, do you think?"

"Don't worry, I think Cao Xi's proposal is very good. The base should be hidden and cannot be built in the valley. Although the magnetic field here is chaotic and the enemy cannot use satellites to view it, people and aircraft can sneak over. There is still a risk. Hiding in It's different inside the mountain, people can't see it, and the missiles carried by the aircraft can't do anything to the solid soil here." Luo Zheng smiled, and his eyes lit up.

"But time?" Shi Qian reminded worriedly.

"Time is not a problem. The soil here is very hard. Excavation will definitely not work. We need to blow it up. We dig a hole from the cliff and go in. It is a hundred meters above the ground. The soil from the explosion is shoveled out directly and thrown into the valley. There is enough here. It’s big, so earth stacking is not a problem.” Luo Zheng said in a deep voice.

"The earth can be piled up to look like a city, making the enemy think it is a settlement we built, which will confuse the area. When the time comes, it can be placed in the entrance and exit area of ​​the canyon, and it can also be used as a fortification. If an enemy comes in, the fortification can be used to counterattack." Cao Cao Xi suggested.

"Hahaha, good idea." Luo Zheng's eyes lit up and he said with a smile.

"While directional blasting, shovel out the soil directly. Make the hole larger. Send as many engineering vehicles as possible to shovel the soil. It won't take long to hollow out the mountain. The biggest problem in digging holes is the accumulation of soil. Shovel directly from the cliff. The efficiency will be very fast." Cao Xi said happily.

"Bang——" Suddenly a gunshot rang out.
