You are my little desert. Dig a sand pit and bury yourself... Hao Zhi whispers outdated pop songs while digging a hole. It's easy to dig because the sand layer is soft.

When he dug five or six meters deep, Hao Zhi began to gasp: "shit, they all say that astronauts are a tall career. Why do I have to work in the field when I get to Mars?"

Professor Naduo and LeLe laughed when they heard him complain while working.

"Thirty meters, why do I suddenly think of a word and dig my own grave! I'll dig a pit and bury myself with the battery. It's really hard and tired. When will this thing be dug..."

"Save your energy and mumble. You'll have to jump back later!"

Hao Zhi gasps for breath. He is so tired that his back hurts. From time to time, he straightens up and beats his back. By the way, he takes a look at the depth displayed by the navigation watch he is wearing. It is already 15 meters, and there is still half the depth.

A big pit 30 meters deep, a huge inverted cone as high as a ten story building, is a very arduous task to dig out by one person.

When Hao Zhi dug more than 20 meters deep, he felt that he couldn't move. His arms were so sour that he could hardly lift them up. He only dared to fill half of the shovel with the sand he dug. Now he didn't dare to fill half of the cloth bag he had filled every time. He had to take heavy steps, drag the cloth bag that sank like a mountain, climb to the edge of the pit and fall on the edge of the sand pile like a hill, With a long sigh, he returned to the bottom of the pit with an empty cloth bag.

The less he loaded, the more he worked, the more tired he was. Although his clumsy spacesuit was not heavy, it affected his activities, which made him a little angry.

"Ma, what about the tall space operation? What about the long-distance space travel and double flight vacation? Did future generations write that when they recorded it in history? Hao Moumou, the founder of human civilization, personally dug a huge pit 30 meters deep, then tired himself into a dead dog, and finally died with the nuclear bomb?"

Many professors and LeLe couldn't reach out, so they had to turn to the microphone to encourage him. Come on, come on, hold on! Stick to the last few shovels

The sound of refueling was like chanting scriptures. Hao Zhi's single was circulating in his ear, which made him a little unbearable. Finally, he was so angry that he threw the iron shovel far away, just sat at the bottom of the pit and gasped. I... I can't do it anymore! Either of you can do it. Don't just stand and talk. It doesn't hurt your back

"Hao Zhi, hold on for the last time, it's already 28 meters!" the professor encouraged him in a loud voice.

"You old tin box! Who are you kidding?" Hao Zhi looked at the measuring device on his wrist. "It's only 21 meters. Do you think I'm stupid?"

Professor Naduo covered the microphone with his hand and laughed with Lele. Accidentally, the microphone was not covered tightly. Hao Zhi clearly heard the two people giggling in his headset. His nose was almost out of breath.

He stood up, grabbed the shovel and shoveled it toward the bottom of the bunker again. He heard a local noise, sparks splashed, and the huge recoil force bounced Hao Zhi back to the ground, numbing his wrists.

Did you dig into the core of the earth? Hao Zhi muttered and got up again. I'm a god man. I wouldn't dig so fast

In the sand, a triangular piece of metal slanted out, sharp, like a corner of a mobile phone.

"Professor, I found something!" Hao Zhi excitedly forgot his pain, threw away his shovel and began to dig the earth with both hands.

After planing for a long time, I found that the triangular metal was just the corner of a large object buried in the soil and sand. Dig deeper and bigger. After planing for a long time, I gradually planed the size of a door panel

Hao zhileng was stunned. He stretched out his hand and gently stroked the "door panel" obliquely inserted in the soil. He carefully studied the dense structure on its surface and reflected the dark cold light

What is it? Professor nado pressed anxiously at the other end of the communicator.

"I don't know what it is, but it's definitely not formed naturally!" Hao Zhi knocked on the metal block with a shovel and echoed Dangdang

"It's like a wing!" Hao Zhi suddenly realized that the semi arc structure of this thing is very close to human aircraft wings!

"Wait a minute!" Professor Naduo threw himself on the computer keyboard and began various operations. He called out the ultrasonic scanning system and remotely scanned Hao Zhi's deep pit.

This thing is like bats and dolphins. The sound waves sent out touch different parts of the object and then reflect back. According to the different reflection time, we can completely outline the holographic image of the scanned object!

Three minutes later, on Professor Naduo's holographic display workbench, the virtual image of a model aircraft composed of fluorescent green lines floats silently and rotates 360 degrees, showing its proud identity from different angles.

"Hao Zhi! This is really a spaceship!" Professor Naduo clenched his fist excitedly, "and judging from its shape and structure, it is definitely not an earth human aircraft, and its structure is quite exquisite!"

Hold the grass! Hao Zhi jumped up, and his inner universe burned in an instant. He also forgot the bitterness and pain. He swung it quickly, pulling heavy sandbags up and down like a diligent ant.

"Is this guy lazy just now? He's tired to death. Why is he so energetic now?" Lele couldn't help laughing and asked the professor.

People, having a hope and a hope can always inspire a lot of potential power! Professor nado pointed the spacecraft's optical imaging system at Hao Zhi and drew closer and closer. Gradually, a medium-sized fast space fighter appeared completely in front of him!

This aerospace fighter is composed of a main body and two suspension parts, like three peppers connected in a triangle. The front is round and the back is pointed. The three parts are slender, uniform and smooth. The three parts are connected by wide channels. The lower two are obviously landing racks that also serve as power cabins, while the upper main body extends two rows of wings in a sharp rhombic structure and bends exaggerated backward, It seems to announce to the world that I am a high-tech product built for flying.

There is no need to think about this thing with your toes. You can feel the arrogance and coldness containing advanced technology as long as you glance at it.

"I don't know how many years this thing has been buried here?" Hao Zhishan walked around the plane with a shovel in his hand, trying to find the boarding gate, but after looking for a long time, he didn't find any gap to close, and its surface was smooth and frightening.

He once saw the metal molds made by some Japanese auto parts manufacturers to show off their technology on the Internet. After the hollow letters are filled into the molds, they become a complete metal square without leaving any trace.

However, it can only be accurate to a very small mold. If the overall design and manufacturing of such a large Aerospace fighter can be accurate enough to leave no gap of half a millimeter, what kind of technology should it be
