Mobile City Farming Guide

Chapter 245 Construction of Underwater Living Cities (4K)
"That's incredible! You guys are absolutely incredible!"

Carson exclaimed in admiration.

To be honest, the moment the mountain demons launched their attack, he had already prepared his convoy for their escape.

Especially when he saw the mountain demon split into countless mountain demons attacking, his expression changed drastically, and he wanted to step on the gas pedal to the floor.

But Tomorrow Alliance managed to hold them off thanks to their powerful firepower.

Upon hearing this, Li Ye chuckled to himself.

The Alliance of Tomorrow must hold out on land, as none of the mobile cities have been modified for sea travel and cannot retreat to the sea.

"But then again, no matter how hard your convoy tries to escape, you can't escape to the sea," he couldn't help but say.

Carson shrugged.

"Oh, our base vehicle is amphibious."

Li Ye was somewhat taken aback when he heard this.

".Is that so?"

My impression of the base vehicle improved even more.

After regaining his senses, he took a deep breath, vigorously stroked his face, and boarded the Black Hawk helicopter, heading towards the corpse of the Mountain Demon.

After seeing the mountain demon fall, a strange light appeared in his eyes.

"This drop is actually pretty good!"

[Tier 3 Orion Cruiser Design Blueprints]

[Design blueprints for a Level 4 "Planet Echo" satellite]

Whether it's a level 4 item or a level 3 item, they're all top-notch.

The crowd that gathered around were stunned when they saw it.

Li Ye was the first to look at the satellite design drawings.

【Item Name: "Planet Echo" Observation Satellite】

[Level: Level 4]

【附带效果：1.信号延迟-30% 2.分辨率+25% 3.探测范围+15%】

[Crafting Requirements: 500 units of Iron Ore (Level 4), 200 units of Precision Alloy (Level 4)]

"It's actually an observation satellite?" Rino pondered.

Back on Earth, out of curiosity, he had specifically sought out information about satellites.

There are several types of satellites.

Communication satellites transmit signals such as television, radio, telephone, and the Internet to achieve global or regional communication.

Navigation satellites that provide precise positioning, navigation, and time synchronization services.

Remote sensing satellites monitor the surface of planets and acquire observational data on weather, environment, and topography.

Military satellites that support national defense, military and security missions and are responsible for detection, early warning and communications.

Rescue satellites responsible for rescuing astronauts and the space station.

Weapon satellites equipped with high-powered weapons and specifically designed for ground strikes.

After regaining his senses, Li Ye sighed softly.

"Ugh"

What he wanted was a super composite satellite that integrates many special functions such as navigation, observation, communication, military security, and ground attack.

"Let's just make do with this observation satellite for the early stages of level 4."

He already has the design blueprints for the TianSuo III rocket. All he needs to do is obtain the design blueprints for the fourth-stage rocket launch platform. Once Tomorrow advances to the fourth stage, it will be able to launch satellites into the sky.

However, before that, he still needs to train the corresponding personnel for rocket launch and satellite operation.

接着他看向了那200单位的4级精密合金，根据图纸介绍，每一单位精密合金需要由1单位4级铁矿、1单位铜、银、金矿，以及1单位的任意4级稀有矿石。

After carefully storing the satellite design blueprints, I left the field to continue appreciating the remaining blueprints.

The Orion Cruiser has the following additional effects: "Missile launch speed +35%, range +20%, and fuel consumption reduced by 20%." It requires 900 units of Tier 3 Iron Ore and 150 units of Tier 3 Precision Marine Components to build.

The City Building Multifunctional Repair Platform has the added effects of "Repair Efficiency +35% and Energy Consumption Reduced by 15%". Its construction requires 275 units of Level 3 Iron Ore. Its primary function is to repair land, sea, and air vehicles. Each repair requires an amount of Iron Ore or Steel equal to the size of the vehicle, and the building itself utilizes the City Platform function.

The "Hercules" single-person engineering robotic arm has the effect of "Engineering Strength +35%" and requires 60 units of level 3 iron ore to craft. Visually, it's a pair of giant, equipable robotic arms that look quite imposing—more like something for fighting than engineering work.

The solar panel power generation sequence has the added benefit of "solar energy conversion efficiency +55%". It can provide 15% of the city's energy when operating around the clock and requires 150 units of level 3 iron ore to build. It occupies significantly less space than the energy windmill sequence and is also cheaper to build.

"I must say, the quality of these blueprints is exceptionally high!" Fang Yong exclaimed.

Li Ye nodded slightly.

He originally thought that the design blueprints dropped by the Mountain Demon were of average quality, and there might even be duplicates, so he had already planned to sell the blueprints to generate income.

After collecting his spoils, Li Ye looked into the distance.

After this fierce battle, the entire peninsula was in complete chaos, with wreckage everywhere.

However, the road leading to the inland area has been cleared.

After thinking for a moment, Li Ye took something out of his pocket.

That was the Level 4 satellite phone that Albert had given him before.

After the call was connected, Albert's smug voice came from the other end of the line.

"Is that you, kid? We're way too far apart this time, you can't try to take advantage of me!"

Upon hearing this, Li Ye couldn't help but chuckle.

He briefly recounted what the Tomorrow Alliance had seen and heard in the Guixu Peninsula region.

"What? You actually went to Guixu Continent?" Albert asked in surprise. "Wait a minute, it seems the higher-ups of the Apocalypse Cult have some plans there. I'll go check it out."

A flurry of busy sounds came from the other end of the phone, and upon closer listening, it sounded like a baby crying.

Li Ye was initially puzzled, but quickly figured it out.

Like Bishop Whiteman, Albert had already arrived home.

He is with his family now.

A few minutes later, Albert returned.

“Since you’re in the Peninsula region, you might as well do the Apocalypse Church a favor,” he said.

"What kind of help?" Li Ye asked instinctively.

He learned about the Apocalypse Church's plans from Albert.

Establish three underwater cities in the waters near Guixu Island.

According to the plan, each underwater city is large enough to support 5 people and can achieve self-sufficiency.

To this end, an engineering-type city dispatched by the Apocalypse Church has arrived in the waters near the peninsula.

What the Tomorrow Alliance needs to do is protect it during its construction. "That's feasible," Li Ye replied.

This was indeed a simple matter; he only needed to deploy the fleet.

During this period, the Tomorrow Alliance does not need to rush to the inland. They can continue to collect metal resources and gather wild resources in the peninsula area.

If one is truly curious about the situation inland, a reconnaissance aircraft can be dispatched.

As he pondered this, Li Ye realized something, and a hint of surprise appeared in his eyes.

Unbeknownst to many, the Tomorrow Alliance had actually conquered the peninsula region.

The main reason is that we dealt with that mountain demon—compared to it, the remaining demons in the peninsula region are really no match for it.

Two hours later, the Apocalypse Church's Level 3 engineer city "Holy Machine A91" joined forces with the Tomorrow Alliance.

Upon seeing the appearance of the Holy Machine A91, everyone was stunned.

Its appearance is almost identical to that of a submersible city, except that its outer shell is equipped with a large number of robotic arms, claws, and cranes. Judging from its appearance, these engineering devices seem to have been waterproofed for underwater operations.

The high-ranking bishop in charge of commanding the Sacred Machine A91 spread his hands out.

“Don’t be too surprised; underwater engineering can only be carried out in engineering-type cities in this way,” he said.

Just as Li Ye was about to speak, Zhou Xing, who was beside him, clenched his fist and clapped his hands, speaking excitedly.

"Oh, I get it!"

Following this line of thought, he speculated that engineer-type cities would certainly have excavation-type equipment for carrying out engineering construction deep underground. There would also be aerial equipment for carrying out engineering construction at high altitudes.

“Your line of thinking is correct,” the High Bishop nodded.

During their conversation, Zhou Xing also showed a hint of regret. This time, the Engineer couldn't help. He could only choose to board the Sacred Machine A91 to observe.

The high bishop indicated that he could not continue chatting and had to get to work quickly.

Liye then began to arrange a series of post-war tasks and started to deploy his fleet abroad.

After completing all this, he boarded the Holy Machine A91 with Zhou Xing.

Yes, he is also very curious about the construction of underwater living cities.

Under their watchful eyes, the Holy Machine A91 began the construction of the living city in an orderly manner.

The first step is, as usual, site selection and exploration.

The A91 is equipped with a deep-sea exploration fleet consisting of engineering submarines, unmanned probes, and deep-sea drones, in order to conduct comprehensive mapping of target sea areas.

The geological stability of underwater cities is crucial; they must avoid earthquake zones and volcanic areas, and also consider depth and pressure adaptability. Generally, locations at the edge of the continental shelf are chosen.

Ideally, it should also be near mineral resources, hot springs, and methane hydrate.

The second step is to build the initial framework of the city.

The A91 submersible then descended to permanently fix twelve pre-fabricated superalloy bases, each over 500 meters in diameter, to the seabed using hydrothermal welding technology. These bases will serve as the load-bearing pillars for the underwater city, each capable of withstanding pressures of up to one million tons.

With the base in place, the Sacred Machine A91 released thousands of hexagonal glass dome units, which would automatically unfold in the deep sea, connecting with each other via a magnetic docking system, gradually forming a hemispherical living space several kilometers in diameter above the seabed. The dome surface is covered with a hydraulic metal coating whose strength automatically adjusts with water pressure, enabling it to withstand deep-sea pressure.

The third step is modular urban construction.

Similar to the underground city construction in the basin area, the engineer-type city will produce hundreds of prefabricated city modules of various types, which will be transported to the target sea area by giant transport submarines or giant anti-gravity floating boxes.

The first modules to be deployed are the command center, energy core, and life support system.

Secondly, there are buildings and various living modules.

Li Ye couldn't help but raise a question.

"Is such a magnificent glass dome only a Level 3 project?"

The high bishop shook his head.

"Of course not, it's a Level 4 project. It was brought specifically by the Holy Machine A91 when it set sail. Not only that, many of the buildings in the underwater city are also Level 4 projects, produced and built by a Level 4 mobile city and then handed over to the Holy Machine A91."

"Hmm," Li Ye nodded slowly.

To ensure safety, the underwater city will be equipped with camouflage and signal jamming devices.

The A91 will also construct tunnels and subways between the three underwater cities to facilitate communication and the flow of supplies.

"Where does the energy for the underwater city come from?" Zhou Xing couldn't help but ask.

The high bishop gave a reply.

First, underwater cities will construct electrothermal wells that drill into cracks in the earth's crust and generate electricity using temperature differences.

Second, tidal turbine arrays will be deployed around the city, using ocean currents to replenish energy through rows of underwater generators within the arrays.

Third, miniature nuclear power plants will be built in underwater cities.

Seawater filtration systems and vertical farming fields are also essential, the latter of which will also grow a large number of graded crops.

The other party also emphasized one point.

All survivors who move into the underwater city need to undergo progressive stress training, otherwise they will not be able to adapt in a short time.

The underwater city will also project landscapes to prevent people from developing deep-sea claustrophobia.

During the conversation, this underwater city is gradually taking shape.

Suddenly, an idea popped into Liye's head.

"Are there underwater cities living in places like the deepest trenches in the ocean?" he asked.

The high bishop smiled slightly.

"Your idea is certainly far-fetched, but it does exist."

"really?"

“Of course.” The High Archbishop nodded. “The three major human organizations have naturally gone to great lengths to settle the people in the wasteland, especially after the abolition of the Silence Protocol.”

Li Ye then proceeded to raise a series of questions.

He wanted to know exactly how many underwater cities humans had built 10,000 meters below the sea, and what their scale was.

The high bishop simply shook his head slightly at this.

"These are top-secret documents, I'm sorry I have no comment."

Zhou Xingyi also raised a question.

Are there cities where people live underground?

The high bishop simply shrugged.

"If you want to know more, then explore it yourself."

Having had his fill of visual enjoyment, Li Ye decided to leave and return to the Tomorrow.

Zhou Xing watched with great interest from the sidelines.

As he was leaving, Li Ye suddenly realized something.

"How many types of building blueprints does a mobile city need to purchase to build a qualified underground city or city?"

"Not many, maybe a hundred or so," the high bishop replied.

"Huh?" Li Ye was stunned.

After regaining his senses, he shook his head gently with a wry smile.

It seems that developing an engineer-type city requires just as much investment as developing a raid-type city!
However, its engineering capabilities are also extremely strong.

I wonder if the Alliance of Tomorrow will be able to grow the Engineer to this size in the future.
