At night, when the moon was in the sky and the visibility of the desert was still about ten meters, everyone dug a sand pit about two meters deep, and under the command of Xiaoyu, some steel was thrown down, and the magician led the four of Matos to skillfully build a square shelf.

The steel frame is like a box, the bottom is pressed on the fine sand, the fine sand is tight, the stability is good, the magician instructed everyone to continue to assemble a cross, the four handles are about one meter long, and the middle is a circular card slot, Yang Zheng happened to come over and called the falcon to sentry for himself, just saw this scene, I didn't understand, but I didn't ask much, and observed curiously.

Not long after, Xiaoyu brought a special drill bit, the outer diameter is about thirty-five centimeters, the magician picked up a pipe to connect the drill bit, threaded, and quickly tightened, after that, the magician said through the headset: "Fatty, confirm again, is it the position under my feet, don't miss." ”

"Don't worry, through the positioning of your mobile phone, make sure it's at your feet, rest assured, as long as you don't deviate when you hit down, you'll be fine." The fat man's voice rang out.

"Then I'll fight." The magician said, plunging the drill bit from the middle of the iron frame, perpendicular to the ground, and using the curved card slot up and down to secure the tube.

The iron frame is one meter high, after the top and bottom are fixed, the pipe is erected, Xiaoyu took out a horizontal caliper and measured it, the iron frame is a little uneven, the magician immediately adjusts the iron frame, and then, Xiaoyu takes out a vertical ruler to measure it, and nods after making sure that there is no problem.

"Old horse, help." The magician shouted knowingly, picked up the cross-shaped tool, and the two of them worked together to jam the tube in the middle of the cross-shaped tool, and the tube had a deep spiral pattern on the outside, and it was very stable after being stuck, and the two grabbed the protruding pipe and spun it.

This scene made Yang Zheng sound the hometown artificial push stone mill, four protruding pipes can make four people exert force, everyone walked in one direction, the huge stone mill rotated, and now it is the same, the pipe rotates under the drive of Yang Zheng and Matos, and the drill bit goes to the ground.

Yang Zheng jumped out of the sand pit curiously, came to the iron shelf to take a look, and found that the parts that fixed the pipe up and down were also spiral, which just matched the texture of the pipe's appearance, so that once the pipe rotated, it could only drill down, and rotate in reverse, and the pipe could be withdrawn.

"Xiaoyu, your design is good." Yang Zheng smiled, his eyes falling on the sand that bubbled out with the depression of the pipe, just like a drill drilling wood and sawdust coming out.

The sand is small and the grooves are deep, as long as the speed is not fast and the strength is large enough, it will not be blocked, as long as the sand is not blocked, the drill bit can be drilled all the way down, Yang Zheng looked at this scene and smiled, and continued: "Xiaoyu, can the speed be faster, it won't be blocked, right?" ”

"It can't be too fast, it's all sand underneath, it won't be blocked, we tested it, if it's dirt and rocks, it's hard to say." Xiaoyu hurriedly said.

"That's good, we have one night, is that enough?" Yang Zheng asked.

"That's enough." Xiaoyu said confidently.

As he spoke, Yang Zheng saw that a pipe was drilled down for most of the time, and the magician picked up another pipe and connected it, there were threads, and it was easy to tighten, and after adjusting and overlapping the spiral patterns on the surface, the magician signaled to continue drilling, and Yang Zheng smiled when he saw this scene.

A pipe will be down in about three minutes, one hundred and three hundred minutes, that is, five hours, and it can be completed without waiting for dawn, Yang Zheng breathed a sigh of relief, climbed into the sand pit, and told through the headset: "Fatty, keep an eye on it, find a sandstorm or the enemy to warn in advance." ”

"Understood." The fat man hurriedly agreed.

Everything was going on in an orderly manner, and Yang Zheng motioned for the troops to be divided into three, some of them stayed below to punch holes, some of them were put on guard, and the other part was to eat some dry food to rest, and they would rotate after an hour.

The drill bit is special, the drilling speed is not fast, there is no need to worry about the wear of the drill bit, the punching is very smooth, Yang Zheng put his mind at ease, and from time to time contact the fat man, to make sure that there is no danger around, time is lost unconsciously, nearly six hours or so, the person who is playing short obviously feels that it is loosening down, and quickly stops.

The magician who was resting rushed to check when he heard the news, and hurriedly said through the headset: "Fatty, check it immediately, is it through?" ”

The fat man hurriedly made a tree hole: "The locator installed from the drill bit shows that it overlaps with the location of the underground river. ”

"That's supposed to be through, that's great." The magician was overjoyed and brought a rucksack.

The backpack opened, and the magician picked up a special bomb, the bomb was small, there was a timer on it, and it was hung down with a rope, and it didn't take long for the magician to feel that the bomb had stopped, and the rope continued to drop a little, no longer vertical, indicating that the bomb had reached the bottom, and he was overjoyed.

Soon, an explosion came from the pipe, buzzing, and it didn't dissipate for a long time, Yang Zheng said worriedly: "It won't blow up, right?" ”

"No, it's just going to blow up loose, the drill bit drops, I've tested it several times, and there was no mistake." The magician said.

Yang Zheng knew that the magician's magic ability was very strong, so he was no longer worried, everyone waited patiently for a while, the buzzing in the tube disappeared, and the magician took out a camera that looked like a spider, which could emit light, and hung it down with a thin rope, and after feeling the bottom, the magician stopped and took out the tablet from his backpack.

Soon, the magician used the tablet and the spider camera to establish a link to the information, and a picture appeared on the screen, surrounded by black, with a bright light in the middle, through which some impurities could be seen, and the magician controlled it, and said in surprise: "Captain, it's done, it's an underground river." ”

"Great, can you figure it out?" Yang Zheng said in surprise.

"The water is only about a foot deep and about two feet wide." The magician said in surprise.

"Great, act according to plan." Yang Zheng was overjoyed and decisively gave the order.

Seeing that Yang Zheng climbed the sand pit, Matos followed, walked to Yang Zheng's side and said sincerely: "They are very powerful, this kind of attack tactics is too incredible, it is estimated that the enemy does not know why when he is dying." ”

"yes, I didn't expect it to happen." Yang Zheng said sincerely.

"It's good that we are our own people, and it's scary to be your enemy." Matos said heartily.

"How?" Yang Zheng asked curiously.

"Others judge who wins based on their combat effectiveness, your attack tactics are too weird, you can't prevent it, you can win without people at all, in your words, you can kill the enemy thousands of miles away." Matos said.

"You know a lot about our culture." Yang Zheng smiled proudly.

"I've heard about some, but I don't know much about it, but I heard that your country's art of war is very remarkable, and I have the opportunity to study it well." Matos said heartily.

"Okay, I'll give you a set of books on the art of war." Yang Zheng smiled, in a good mood.
