123: Chapter 123 Three-story building, 48,000 square meters! The interior of the fortress is incredibly comfortable.

Lu Chen stood up from the driver's seat.

The cockpit's space was more than ten times larger than before the upgrade.

Six fire control displays were lined up on the long console, each twice the size of the previous ones.

The radar panels had gone from one to three, covering the entire left side of the console.

The red button for full weapon synchronized salvo was quietly embedded just above the right armrest, its indicator light glowing with a green standby light.

He walked forward two steps, coming to the windshield.

The height of the windshield had changed from the original 1.2 meters to 3 meters, and the width exceeded 6 meters.

He looked out through the glass.

The ice of the Rustwind Wasteland spread out thirty meters below.

The cockpit was located at the front of the third floor of the fortress, about twenty-two meters from the ground.

The two-hundred-meter snow-free zone created by the wide-area high-heat dispersal generator was clearly visible.

The circular snow-free boundary drew a perfect circle around the fortress.

The ground inside the circle was moist, while the outside was covered in white snow.

The system prompt sounded right on cue.

[ Internal Structural Layout of the lv.3 fortress-class Mobile City ]

[ First Floor (Bottom Layer): Main Engine Room, Main Track Drive Group, Fuel Storage Area, Large Material Storage Area, Mechanical Arm Root Anchoring Area, Cold Storage Cluster. Ceiling height: 10 meters. ]

[ Third Floor (Top Layer): Cockpit and Command Center Front, Fire Control System Integration Area Front, Under the Planting Greenhouse Dome, Area approx. 14,000 square meters. Ceiling height: 10 meters, including the dome's highest point of 31 meters. ]

[ There are 4 sets of industrial elevators and 6 metal staircase passages between each floor. ]

48,000 square meters.

Three floors.

16,000 square meters per floor.

From a 100-square-meter tin shack to a 48,000-square-meter three-story steel lv.3 fortress.

Lu Chen's fingers tapped lightly on the seam of his trousers.

His obsessive-compulsive disorder was acting up.

He needed to walk through it.

Every floor, every cabin, every piece of equipment.

He walked out through the back door of the cockpit.

The width of the corridor had changed from less than one meter before to three meters.

The ceiling height was ten meters.

The inside of the walls was covered with a matte silver-gray thermal insulation coating that felt warm to the touch.

There was an LED wall lamp every ten meters on both sides of the corridor, providing even and stable light.

The temperature was twenty degrees.

The entire interior of the fortress was kept at a constant temperature of twenty degrees.

The air was filled with a faint metallic scent and the fragrance of fresh plants.

The metallic scent was emitted by the newly generated steel structures after the upgrade, which had not yet fully cooled down.

The fragrance of plants drifted over from the direction of the dome greenhouse.

He walked fifty steps.

He passed through an automatic airtight door.

In front of him was the greenhouse area on the third floor.

The dome arched overhead at a height of twenty meters.

Transparent composite material panels blocked out the darkness outside, and the full-spectrum LED strips inside the dome simulated the intensity and spectrum of midday sunlight.

The greenhouse area spread across the entire back half of the third floor.

14,000 square meters.

Fourteen standard football fields.

The hydroponic planting racks had gone from three levels to nine, and each set of racks had grown from three meters long to twenty meters long.

Twelve sets of planting racks were arranged in two rows, leaving a three-meter-wide working aisle in the middle.

The planting troughs on each level of the racks were equipped with independent nutrient solution circulation pipelines and temperature control probes.

Lin Wan stood in the middle of the aisle, a folding dagger hanging at her waist, a communicator clutched in her right hand.

She looked up at the dome, her neck tilted back so far it was about to snap.

"City Lord!"

She spotted Lu Chen.

She ran over, jogging.

The aisle was too long; it took her a full fifteen seconds to reach him.

"Did you see it!"

Her face wore an expression Lu Chen had never seen in thirty-three days.

Completely devoid of fear, tension, or caution.

Only the ecstasy a Botanist would have when standing at the gates of heaven.

"A 14,000-square-meter greenhouse! Independent lighting! Independent temperature control! Independent irrigation!"

She gestured excitedly with her hands and feet.

"Nine-level hydroponic racks! Twelve sets!"

"My watermelon seedlings and strawberry seedlings have all been transplanted into the new planting troughs! The nutrient supply for each plant has increased threefold compared to before!"

She pointed to those lush, green racks.

"If we fill all the racks! Calculated according to the production efficiency of the grade a seed vault varieties! City Lord! This greenhouse can feed three thousand people!"

"Vegetables and rations for three thousand people!"

She caught her breath, her chest heaving violently.

"Plus the protein from the twelve protein synthesis units that provide daily protein for six hundred people!"

"And adding the output of this greenhouse!"

"The food problem for three thousand six hundred people can be completely solved!"

Lu Chen looked at her.

"Not enough."

Lin Wan's excitement paused for a beat.

"Thirty thousand people." His tone was no different from when he was reporting inventory lists.

"Three thousand six hundred is just a fraction."

"I know." Lin Wan bit her lip.

"But this is the first step!"

She perked up again.

"Once the watermelons and strawberries mature! The seeds can be propagated for a second generation."

"Within half a year, I can increase the output to feed over five thousand people."

Lu Chen did not dispute her numbers.

"Start by utilizing the existing planting area. I'm going to go check the other equipment."

"Okay!"

He turned and walked towards the staircase passage on the third floor.

The metal staircase was two meters wide, and the welding craftsmanship was more than twice as precise as in the Lv.2 era.

He walked down the stairs and entered the second floor.

The corridor on the second floor was wider than the one on the third floor.

On the left was the residential area.

The number of metal beds had gone from two to sixty.

Each cabin had eight beds, equipped with independent thermal insulation doors and ventilation ducts.

On the right was the protein synthesis unit group.

Twelve stainless steel machines, each half a person's height, were lined up in a row.

Each was connected to an independent feed pipeline and discharge port.

The feed pipelines converged into a centralized organic raw material storage cabinet.

Below each discharge port was a tray, and the first batch of finished products was already on the trays.

Twelve long, strip-shaped nutrition bars were neatly arranged in the trays.

Beef flavor.

Lu Chen picked one up.

The surface had a slight sheen, the texture was firm, and it weighed about 150 grams.

He broke it in half.

The cross-section was fine and even, dark brown in color.

He put it in his mouth.

He chewed three times.

The texture was on the harder side; it did taste like beef, with a slight smoky aftertaste.

The protein content was sufficient.

It was edible, but not delicious.

But on the frozen wasteland at minus fifty degrees, being able to eat was a luxury.

"Twelve units, daily supply for six hundred people."

He put the remaining half back on the tray and continued deeper into the second floor.

He walked past the protein synthesis unit group, past the weapons and ammunition storage area, and past a room he had never seen before.

The nameplate on the door had five characters.

Basic Medical Module.

The door was closed.

He pushed the door open.

The ten-square-meter space contained a metal diagnostic table, a wall-mounted medicine cabinet, and a basic vital signs monitor.

The medicine cabinet was empty.

The monitor's screen was black.

There was no cable plugged into the power port.

The basics of the basics.

But this was the first time the Polaris had medical facilities.

"It will be better in the future."

He closed the door.

He walked toward the stairs to the first floor.

The first floor was the power core of the entire fortress.

In the spacious area with a ten-meter ceiling height, the main engine group occupied the back half.

The volume of the lv.3 steam turbine and diesel-electric hybrid power group was four times larger than in the Lv.2 era.

The turbine diameter had gone from half a meter to two meters.

Judging from the numbers on the panel, the power output of the generator set was five times that of the Lv.2 era.

Thick cables extended from the generator set in all directions, running along the ceiling's conduit channels into every cabin on every floor.

He took a look at the operating status of the main engine.

Idling, power output at eight percent.

Only maintaining lighting and heating for the entire vehicle.

The cold storage cluster was in the left area of the first floor.

The cold storage space had gone from two cubic meters before to forty cubic meters.

Enough to store two months' worth of frozen meat.

He had completed the first round of inspection of the entire lv.3 fortress.

Except for the medicine cabinet in the medical module being empty, all other equipment was in normal operating or standby status.

48,000 square meters, three floors, twelve protein synthesis units, a 14,000-square-meter dome greenhouse, a two-hundred-meter radius snow-free zone, and a fully restored Mechanical Arm and ramming prow.

From a twenty-meter war chariot to a two-hundred-and-six-meter lv.3 fortress, thirty-three days.
