"Well, don't rush to practice all the keels. Come one by one, check the keels you have already practiced, and report them immediately when you find any problems!"

Lan Li nodded while not forgetting to remind him that each keel is built with huge manpower and material resources, and all are planned separately according to the design.

Moreover, this keel is used to withstand the entire huge Mars. It is used to install the engine to withstand various forces, so its design has been carefully considered.

First of all, its materials are not simply iron. The asteroids used for smelting are carefully selected. The iron content is high enough, but it also contains some other elements that can be trained together to ensure sufficient strength and toughness!

Secondly, all factors are considered in the design. The places need to be reserved for grooves or bumps, etc., have been strictly calculated and designed, and all are built in one go.

Only in this way can the keel made of all steel and steel be able to withstand the huge mass of the Mars and be used to install multiple nuclear fusion engines to withstand powerful thrust and pulling forces!

"Don't worry! We understand this!" His subordinates and those who were used to Lan Li had to remind him again and again about everything. If they didn't want to be scolded by Lan Li, they must take it seriously.

"Well, that's good! The construction of Mars is a major event in our Qingquan, so everyone should cheer up!" Lan Se's expressionless face, and she has always had very strict requirements at work!

The huge keel that has been refined was tightly grasped by countless huge arms. Starting from the beginning, various instruments are constantly scanning, and the three-dimensional images are transmitted to the computer, and carefully compared with the pre-designed data!

"Didi~~" When Lanse heard this sound, her eyebrows frowned. Because the appearance of this sound meant that something was inconsistent with the design in some places, so she quickly looked over!

"At 200 meters away from the A end, the diameter here is 20 cm thicker than the design, and the length is about 20 meters!" The computer automatically adjusted the difference data.

"Analyze the reason immediately, why it becomes 20 cm thicker here!" Lan Li's head stared at the differences and data, while constantly analyzing the reasons for the differences in her mind.

The length is 50 kilometers and the diameter is 1 kilometers. This small difference is actually very trivial, but in space, any slight difference may cause a difficult event, so it must be taken seriously!

"The differences are not important connection areas, and they will not affect the overall performance of the keel. You only need to cut off the excess!" The first thing that came out is the report on the impact of the difference on the keel!

"It's not an important place, and it's still thick. You just need to cut off some. If it's a key place and the thickness is not enough, it's miserable!" Lan Se relaxed gently, but immediately thought of something, and his relaxed heart hung again.

This place can be thicker, or it may be thicker or thinner in other places. If it is in a key place, it would be bad!

"Have you found the reason?" Lan Li frowned, feeling extremely anxious. If the keel is not qualified, it would be bad. She could only cut the keel into many small pieces and then return to the furnace to resert.

"The reason was found. A large-scale solar wind just occurred during the smelting. The solar wind blew the entire space factory, causing an error in the accuracy!"

Soon, with Qingquan Technology's technical means, the reasons for the difference were immediately found, solar wind! With a huge space building like Changan Space City and Phase II factory, the impact of solar wind is very huge! Many things need to be completed in a relatively calm period of time for solar wind, and Qingquan Technology's monitoring of solar wind is also very strict, in order to minimize the impact of solar wind as much as possible!

"Solar wind? Didn't the people from the meteorological department notify us in advance?" Lan Li thought for a while and asked.

"I've notified it, but it's different from what they predicted. Their predictions are 1 level different from what actually happened!" The people under him knew that Lan Li's frowning eyebrows were already very angry at this time!

"What do people in the meteorological department do? Even the solar wind will report an error. Record this matter and go back to settle the score with them!" The subordinates read it correctly. At this time, Lan Li was very angry. He finally carefully smelted the keel bones and did not dare to make any mistakes in anything. The people in the meteorological department will even detect errors in the solar wind!

Lan Li was already quite angry at this time. Anyone who is familiar with her knows that someone is going to be in trouble! As the person in charge of the second phase of the factory and the person in charge of the "Mars", Lan Li is already one of the highest levels of Qingquan Technology. She has very great authority and does not require any procedures to punish those who are not doing things.

"Continue to test!" Lan Li calmed down her inner emotions and ordered to continue to test the keel. At the same time, she silently prayed in her heart that she must not make any mistakes afterwards.

Every time the test is completed for a distance, countless mechanical arms will move the long keel for a while. After testing, there is no difference in the future. It is exactly the same as the design. Lan Se finally let go of her heart!

"Change the differences!" Lan Li's frown slowly loosened her beautiful eyebrows, revealing her peerless and beautiful eyebrows. At this time, she was in a pretty good mood. There was only one difference in a keel that was 50 kilometers long, and this difference could still be corrected. It can be said that the refining of the entire keel is very successful!

Qingquan Technology's technology is very advanced after all. In addition, Qingquan Technology attaches great importance to "Mars", and has mobilized a large number of the best scientists. If a keel is not refined well, you don't have to think about building "Mars".

Countless space robot arms moved the keel again, pulling the difference to the corrected area, and several huge robot arms slowly moved over, with a laser cutting instrument above the arm!

A magnetic arm first fixes the part to be cut off, and then the laser cutting instrument slowly emits white tangent light to cut the differences bit by bit. At the same time, the magnetic mechanical arm continuously recycles the cut iron blocks, and these iron blocks cannot be left to them in space!

After the laser cuts the large iron blocks, a new robot arm comes over to make further corrections and polishes the edges and corners. Soon there is no difference between the keel and the data in the design. It is grabbed and firmly fixed by the huge robot arm. It needs to be placed and put and assembled together after the other keels are refined!

The main keels of "Mars" have 9, and 8 are used to form the outer skeletons. One is placed in the middle to support them. These 9 huge keels are the main skeletons, and they also need to be equipped with other large and small skeletons. The combination of large and small skeletons makes it a huge space whale!
