As soon as the last batch of dome modules was transported to the construction site, Jiang Cheng summoned all the management personnel for an engineering meeting at the command center.

"Since all the prefabricated modules for the dome are here, let's start building the dome.

Notify all units' astronauts to focus on completing the dome project next.

We must quickly finish this most difficult part of the work, so everyone can relax a bit.

Jiang Cheng stood in the middle of the command center, issuing subsequent orders to all surrounding management personnel.

The following work is the key of the entire project, I hope everyone stays alert. As long as we can complete the dome's construction, the entire project will be half done.

About to begin the hardest part of the whole project, even Jiang Cheng was a bit nervous.

That's why he repeatedly emphasized this matter in the command center, hoping to capture everyone's attention.

Looking at the entire city's construction timeline, if the dome's construction alone will take up half of the time.

From this point, one can see the importance of this project, no wonder Jiang Cheng was so nervous.

After the construction meeting ended, everyone dispersed to start different tasks.

During the dome construction, everyone has their own responsibility, only by working together can this super project be completed.

On the site with Zhou Tian, there was a circular structure.

This enormous circle is the foundation of the dome, supporting the entire dome's weight.

The foundation of the entire dome had been completed, now it's time to start the ground construction.

The gigantic cranes lifted the prefabricated modules one by one from the storage area to the designated places.

Each dome prefabricated block was numbered, a long string of numbers indicated where it should be placed.

This hoisting work is not simple and requires good coordination and planning as the dome consists of countless prefabricated blocks. Due to the sheer number of blocks, placing each block in its correct position is a massive challenge.

So many prefabricated blocks piled together on site, a slight error may lead to incorrect placement, and the subsequent assembly work would be interrupted.

Jiang Cheng commanded his management staff, spending several days to place all the modules in their designated spots.

Just the preparatory work took a considerable amount of time, which highlights the difficulty of constructing the dome.

Placing the prefabricated blocks is just the beginning; the real challenge lies in the subsequent assembly work.

This prefabricated installation technology, although simpler compared to integral construction, has its relative complexity. Don't be fooled by the mere assembling work, numerous issues need consideration here.

This dome is not like the one on Water Ball; it is a protective layer on Mars.

Therefore, this transparent dome must ensure absolute airtightness.

If gaps appear between the prefabricated blocks, even a slight one could cause a huge disaster.

During the entire dome construction, Jiang Cheng must ensure each prefabricated block fits perfectly before using special techniques to weld them together, forming a solid whole.

Every prefabricated block is pre-calculated before production, and installation errors are unacceptable.

Therefore, during installation, it's crucial to ensure no errors in placing each prefabricated block, all must be installed according to plan.

The points to watch during the entire project are numerous, even Jiang Cheng, the chief, had to be on-site to oversee the work.

After more than two months of work, the dome construction was still ongoing, with Jiang Cheng standing on site watching astronauts assemble those giant prefabricated blocks.

One by one, the prefabricated blocks were hoisted into midair, starting to join with other blocks.

The prefabricated blocks shone brightly under sunlight reflections.

If it weren't for the helmets' built-in glare filters on the spacesuits, people on site might not be able to open their eyes.

Countless transparent modules moved in the air, hoisted to the designated assembly positions.

The most challenging part is when blocks approach each other, requiring repeated adjustments to their positions to piece them together.

After nearby prefabricated blocks were installed, they must undergo rigorous inspection and testing. Every "020" block should have no gaps to proceed to the next step.

Once connected, astronauts use specially designed equipment to weld the transparent blocks together.

This welding equipment, specially designed by Jiang Cheng, ensures strong welds without visible traces.

This special welding method guarantees the whole dome's transparency won't be compromised due to welding issues.

Once the entire dome is assembled, it looks like one whole piece, without a single visible gap.

Standing inside the city and looking up at the sky, people would feel as if they are outside on Mars, as if the transparent dome doesn't even exist.

Only after repeated adjustments of perspective could one barely see the dome's outline.

Such design is what Jiang Cheng aimed for, allowing city inhabitants to feel no constraints, as if being on Mars' surface.

As Jiang Cheng inspected the construction site, Xiao Peng approached Jiang Cheng and said, "The prefabricated blocks in A37 area are almost fully hoisted, do you want to take a look?"

The entire dome construction was divided into numerous zones, each with dedicated personnel in charge of installation.

Many areas were being constructed simultaneously to ensure efficiency. Installing such a large dome bit by bit would take Jiang Cheng and his team several years to complete.

Therefore, they adopted a sectional installation method, each zone first completing part of the dome before connecting various zones.

However, coordination among different areas is crucial; if two sections can't align, both must be disassembled and reassembled.

To avoid such scenarios, Jiang Cheng and the team conducted frequent site inspections, coordinating work progress between different areas to ensure the entire dome could be seamlessly assembled.

Due to the vast area of Mars City, Jiang Cheng was not familiar with the conditions in other zones.

After hearing Xiao Peng's report, Jiang Cheng decided to check it out.

The progress there seems good, let's go see it together.

After speaking, Jiang Cheng led the way to the nearby Mars Rover, preparing to go with Xiao Peng to inspect.
