Mobile City Travel Guide

Amidst the violent roar and tremors, the surging black mist suddenly accelerated and rose, surging up in layers like a tide, engulfing everything in its path.

Finally, after returning to its original height, it stopped churning and returned to calm.

On the deck, Li Xin rested and drank water.

A few minutes later, the Spark came out along with the Iron Mole.

At this moment, the townspeople returned to town, and after learning from Matthew and his sister about their discovery at the bottom, they were all filled with remorse.

"This counts as 300 work points, this counts as 500 work points, and this counts as 1000 work points."

The guild leader, with a serious expression, meticulously examined the siblings' findings.

"Based on your contributions this time, you are qualified to be promoted from Iron Badge to Silver Badge in one go."

The people on the side were curiously watching something.

"This thing seems to be electrically powered?"

"Wow, the technology used in these ruins is truly advanced!"

"It seems like it can spray water from the bottom. Is this a water dispenser? Why don't we try fixing it and have a few sips?"

But actually, this thing is a smart toilet.

Li Xin stared at the large pile of scrap iron on the deck, pondering what to make after melting it down into ingots.

Suddenly, a brilliant idea struck him: "Why don't we just expand the capacity?"

The so-called expansion refers to the process by which a mobile city expands its size through a round of construction in order to gain more internal space.

The benefits of increased space are obvious.

Compared to the poverty and destitution they faced in the wasteland, the Starfire is now fully equipped.

With the addition of about two hundred people, the coal harvested in the world of giants, the large quantities of whale meat and grease, plus the livestock they just acquired... the space in the city is clearly no longer sufficient.

However, expanding a city is no easy task. First, it's necessary to identify what needs to be retained, such as engineering equipment, farmland, and key facilities. Second, a detailed expansion plan must be drawn up to ensure proper space allocation. Finally, sufficient building materials such as steel, timber, and stone must be prepared.

Soon, Li Xin had an idea. During this exploration, he completed the Sky Hunter mission and obtained 1500 evolution points, which was just enough to evolve the city AI so that it could plan and design.

【Item Name: City AI "Yunzhi"】

[Description: An outdated city system with an incredibly old hardware architecture, frequently experiencing lag during operation, and urgently needs an upgrade.]

[Evolutionary Branch:]

[Electronic Girlfriend: Your city's AI will possess a human-like emotional module, featuring a gentle female voice and delicate emotional feedback. It can also be customized with multiple personalities such as arrogant, aloof, adorable, and mature.] - 800 Evolution Points

【未来管家：1.计算效率提升300%，资源调配精度提升95%。2.多线程处理能力达到1000项 3.决策响应速度缩短至0.1秒】-1500点进化点数

[War Goddess: The city AI will evolve into the core of war command, providing combat functions such as battlefield situation analysis, fire coordination, vehicle control, tactical simulation, and enemy situation early warning, and calculating the optimal combat plan.] - 5000 Evolution Points

Li Xin naturally chose the future butler evolution branch. In addition, he was also quite curious and looking forward to the "Goddess of War" evolution branch. However, the Starfire's current combat power was far from growing to a level that could match its capabilities.

After the evolution was completed, the originally old and backward city AI was instantly transformed, and its computing power and processing capabilities increased dramatically.

Based on the new requirements, it generated a detailed expansion design drawing in less than a second.

According to the blueprints, the Xinghuo spacecraft will be expanded from "45 meters long, 28 meters wide, and 24 meters high" to "85 meters long, 50 meters wide, and 36 meters high." Multiplying these dimensions, the volume will be five times larger than before. However, this is only the ideal space; the actual volume will be much smaller.

The amount of building materials needed for the expansion, listed on the blueprints, presented him with a problem. Even considering the inventory and the iron ingots produced from the current scrap metal smelting, there was still a significant shortfall.

In response, Zhang Yue generously offered his assistance.

"Aren't you going to expand the capacity?" Li Xin asked doubtfully.

"I'm only using it to meet daily production needs this time, I won't need too many," Zhang Yue replied. "Besides, the current size of the Iron Mole is just right, it's flexible enough."

The reason for this is that as mobile cities expand in scale, their mobility and speed will decrease, making them appear cumbersome. At that point, they will rely more on external combat forces such as convoys, fleets of ships, and fighter jet groups as a shield.

Mobility.

This is crucial for mobile cities, because no one knows what the next world will be like. Only by maintaining strong mobility can mobile cities ensure that they can avoid enemy attacks and disasters.

Therefore, many lords, even with sufficient resources, did not choose to expand their territory.

Li Xin nodded slowly, naturally agreeing with the theory. However, for the sake of development, expansion was inevitable.

After a full day of intensive preparations, the expansion of the Xinghuo spacecraft officially began.

The main construction was carried out by the Iron Mole using its engineering equipment. In addition, a large number of Rustwind Town residents were temporarily hired to help.

As for the reward, it was the whale oil and whale meat harvested earlier.

The reason they didn't ask their own two hundred-plus men for help was that although the vast majority of them were able-bodied young men, very few of them had any mechanical knowledge. On the contrary, the mechanical skills of the Sky Travelers were extremely advanced; even young children could repair machinery.

Amy was also in the crowd. According to her, the Federation has made mechanical technology the most important course and has long included it in compulsory education.

After a long period of work, Xinghuo finally completed its expansion.

Compared to before, it's a whole size bigger, and has expanded from the original three decks to five. The decks are also much more spacious, even enough to accommodate several city machine guns.

Its interior space has also expanded several times, along with the expansion of production workshops, warehouses, kitchens and other cabins. The population and resources that could have filled the city to the brim are now much sparse, with large empty spaces everywhere.

A hint of satisfaction flashed in Li Xin's eyes. After this expansion, he wouldn't have to worry about insufficient space for the time being. According to Yun Zhi's calculations, the current maximum population capacity of the Xinghuo was 1000 people.

When preparing personnel and building materials, Li Xin even asked Yun Zhi to revise the blueprints and add an extra new warehouse.

This warehouse wasn't used to store food or supplies, but rather to transport vehicles. After upgrading the production workshop, the Starfire was already capable of producing vehicles, speedboats, and helicopters. He originally planned to build some vehicles upon arriving in the new world to facilitate resource gathering and combat operations, but he hadn't expected the next world to be like this.

"I wonder if there will be land in the next world," he thought to himself.
