After confirming the plan, Chen Xiaoyun's action and execution are obviously very high.

Not long after the front foot left Chen Mengchuan, a series of authorizations were obtained, and then planning for the excavation of the urban foundation of the Martian city began.

This time the excavation area and depth are unprecedentedly huge, a circular area with a diameter of 42 kilometers, and a depth of 200 meters to dig vertically!

After receiving the authorization, the first thing Chen Xiaoyun did was to transfer the multi-armed crabs, all the spare multi-armed crabs whose working hours were not full, under the exchange and negotiation between her and Ah Chen, they were transferred one after another, and a large number of newly created multi-armed crabs were also authorized to her.

As a result, the number of multi-armed crabs in her hands soon increased.

The 12 brachial crab manufacturing and assembly factories on Mars every day can assemble more than 2,500 multi-armed crabs, and the scattered multi-armed crabs have reached a rate of 500 multi-armed crabs per day for a certain period of time.

This means that she can be supported by 3,000 multi-armed crabs per day, which is quite a decent amount of control.

Nearly a week later, more than 20,000 multi-armed crabs were already working 24-hour overtime to dig and transport under Chen's Mars City plan.

More than 400 space shuttles have opened more than 400 space source point circles at fixed points in the entire deep pit, so that these multi-armed crabs can transport all the excavated earthwork away as soon as possible.

A seemingly impossible and huge project is constantly excavated at a speed visible to the naked eye in the process of continuous excavation.

Soon, the Gravity Department offered a giant disc gravitational cutter!

This is a 35 cm thick gravitational cutting machine like a disc, the outside is made of dense steel drill bit, and the internal gravitational system is used as a speed drive, the diameter of the entire giant disc reaches 50 meters, and under the high-speed rotation, the rotation and cutting force brought by the entire external physical section is incredibly large.

With the giant disc gravitational cutting machine provided by the gravity department, Chen Xiaoyun quickly adjusted his excavation ideas and quickly made a new plan.

First, the giant disc gravitational cutter cut a columnar square hole vertically in the center of the crater, and then through the cooperation of the multi-armed crab, the entire columnar square mouth was quickly hollowed out, as if a square deep well was drilled.

After that, it was clear that the efficiency was much better.

These giant disc gravitational cutters, like cutting tofu, continue to cut out neat and uniform columns, and a large number of multi-armed crabs are attached, and then uprooted by the high-strength anti-gravity technology award.

In just 4 days, the whole team completed the foundation excavation of the Martian city!

Such efficiency is far beyond everyone's imagination.

It took less than 40 days to dig out a huge pit with a diameter of 42 kilometers and a depth of more than 200 meters.

The pit was so huge that Chen Mengchuan and Toni were a little incredulous when they heard that the pit had been dug.

This is an unimaginably large crater with an area of more than 1,500 square kilometers, which is almost one-tenth the size of Xiajing City, China!

Even after seeing the video screen, Chen Mengchuan and Toni still couldn't believe that such a vast work was really completed by Chen Xiaoyun and others.

After a huge shock, Chen Mengchuan really praised Chen Xiaoyun.

Then Chen Xiaoyun and others began the arrangement and deployment of the second part of the work.

The U-shaped trimming of the edge of the crater has been going on for 30 days, with 20,000 multi-armed crabs laying 24 hours a day.

A large number of metal partitions began to be inlaid to the bottom of the pit with the hard work of the multi-armed crabs, and the buckles and large screws were fixed, and a huge steel plate was soon spread all over the bottom of the pit and the pit wall.

After 30 days, the second phase of work began to be officially completed.

This is a huge basin-type area, and the whole body has been covered with metal, and under Chen Mengchuan's authorization, I don't know how many M-type metal asteroids have been smelted.

In comparison, the construction of the 269 supporting lighthouses was much faster, and with the sufficient supply of materials and the support of enough multi-armed crabs, it only took 4 days to complete all 269 giant constructions, which is like Optimus Prime, which is extremely impressive.

In the past few months, Chen Mengchuan's attention to the entire Martian city has not been high.

But this time, with the support of Zhao Wanyu, the construction of the Martian city has spared no effort to publicize it throughout the earth.

A giant basin-type city built on Mars!

Almost all of humanity is thrilled, and a large number of people are involved!

Different from the arrival of the aircraft on the alien planet, this time, what Tianzhi Technology is doing is to build a city on Mars, a huge Martian city, with an area of more than 1,500 square kilometers! And it is expected to be able to accommodate a population of 1 million to 2 million, which is far beyond everyone's imagination.

The human world is once again shocked by the power of Tianzhi Technology!

A large number of pictures, a large number of videos, are constantly being announced through Tianzhi's Mars City Plan.

This is a huge project that exceeds all human imagination!

Every once in a while, the live broadcast makes all human beings thrilled, which is the ultimate technological power.

In these live broadcast screens, tens of thousands of multi-armed crabs, the division of labor and cooperation, perfectly, quickly carried out the capping work.

This is a multi-layered arc capping with a very complex structure.

In the design of the overall structure, it is the most important part, which must be strong enough to withstand the strongest Martian sandstorms and air waves, and also have the comprehensive effect of regulating the light and air pressure of the entire Martian city.

In the end, the entire Martian city was capped!

When Chen Mengchuan saw the entire material consumption data, the corners of his mouth couldn't help twitching.

This is one of the most consumable items on the Martian base!

There is no doubt that an incomparably large amount of resources has been consumed, and under this massive amount of resource consumption, it is only an empty shell!

But even an empty shell is an unimaginable miracle for mankind!

And the next work, comparatively, is much easier.

According to the overall urban design plan, the huge circular area was divided into zones, and at the same time, the green biological cycle was started.

The soil layer was relaid to a thickness of 20 meters, and a large number of grass seeds and a large number of bamboo seeds were sown!
