125: Chapter 125 All the blueprints are in hand! Lin Xiao fulfills his promise.

6:15 AM.

Lu Chen woke up in the driver's seat.

After six hours of sleep, seventy percent of his physical fatigue had recovered.

The first thing he did upon opening his eyes was to check the radar panel.

There were no abnormal heat sources within an eight-kilometer radius.

The auxiliary engines of the Black Rock City-State were still running, and the iron wall was still parked two kilometers away.

The LED strips on the greenhouse dome had automatically switched to simulated sunrise mode at 5:00 AM, with the light transitioning from dark red to warm yellow, gradually increasing to full sunlight intensity.

Lu Chen got up and went to the public living area on the second floor to wash his face.

The hot water provided by the snow-melting water purifier was clear and odorless, flowing out from a faucet.

He no longer had to crouch in front of a small device only two spans long to collect water.

He took a nutrition bar from the discharge tray of the protein synthesizer and ate it as he walked.

Beef flavored.

The texture was on the hard side.

The protein content was sufficient.

It was edible.

By the time he finished one, he had arrived at the third-floor greenhouse area.

Lin Wan was already inside.

She was lying prone in front of the bottom planting trough of the third hydroponic rack, using a homemade bamboo skewer to check the root systems of the watermelon seedlings.

"City-State Lord! Morning!"

"How are the seedlings doing?"

"They all survived!" Lin Wan stood up straight and pointed at the hydroponic rack, "During the upgrade process, the system automatically transplanted all the crops. The new planting troughs are three times deeper than the original ones, and the nutrient solution concentration has been automatically calibrated to the optimal level."

"Estimated maturity time for the watermelons?"

"Originally estimated at ninety days. They were planted on the thirty-third day, so fifty-seven days remain."

"The lighting and nutrient solution efficiency in the new environment are both better than before." She wiped her forehead with the back of her hand, "It's estimated that they can be ready five to eight days early."

"What about the strawberries?"

"Strawberries are faster. Originally seventy days, now about fifty-five days in the new environment."

"Good."

Lu Chen scanned the entire greenhouse.

Most of the planting racks in the 14,000-square-meter space were still empty.

Only two of the twelve sets of planting racks were in use, with the remaining ten waiting for Lin Wan to expand planting.

"Make a planting plan. Which seeds to plant first, which to keep in reserve, and calculate the planting density and production cycle clearly."

"Give me one day!"

"Half a day."

"Okay!"

Lu Chen left the greenhouse and returned to the cockpit.

The communicator rang.

"City-State Lord Lu Chen."

Zhou Yuan's voice was much steadier than last night.

"I'm here."

"The blueprints have been organized."

"How many?"

"A total of eleven."

"Eleven?"

"The seven I gave you earlier were the first batch." Zhou Yuan lowered his voice by half a notch, "These eleven are the core archives that City-State Lord Lin Xiao kept in the safe, containing all the high-level pre-civilization technical documents collected by The City-State over the past hundred-plus years."

"Are the best ones in there too?"

"City-State Lord Lin Xiao asked me to pass on a message: keep nothing, give them all to you."

Lu Chen glanced at the wall clock.

6:35 AM.

"When can you bring them over?"

"City-State Lord Lin Xiao said he wants to deliver them personally."

"How long until he arrives?"

"He has already set out, coming down from the side exit on the fourth floor. It will take about ten minutes to walk over."

Lu Chen switched channels.

"Lin Wan."

"Yes!"

"Your brother is coming, bringing the blueprints."

"I know."

"Wait in the greenhouse, I'm going to the first floor to open the door."

"Okay."

Lu Chen took the elevator down to the first floor.

The main entrance of the first floor was in the middle section on the left side of the fortress, a heavy airtight door four meters wide and six meters high.

He pressed the physical button to open the door.

The hydraulic drive system emitted a steady hiss, and the four-ton airtight door slid outward.

Cold wind poured in from outside the door.

Minus forty-two degrees.

The ground within five meters outside the door was dry.

The two-hundred-meter coverage area of the wide-area high-heat dispersion generator maintained the temperature of this area above zero.

There was no snow accumulation.

Wind and snow bypassed it.

Lin Xiao walked in from outside.

He was followed by Zhou Yuan and Horton.

Horton was no longer leaning on an iron pipe.

His left leg was bound with a makeshift splint, and he was still limping, but he was walking on his own, with no one supporting him.

Lin Xiao stopped the moment he crossed the threshold of the airtight door.

He looked up at the height of the door frame.

Six meters.

The City-State Lord turned back to look at the outer wall of the fortress he had passed before walking in.

A thirty-meter-high steel wall rose from the ground, covered with thick, sloped armor plating.

The surface of the armor plating featured lv.3-grade bullet-deflecting geometric ridges.

Heavy track assemblies extended beneath the chassis on both sides of the fortress, with each track plate exceeding one meter in width.

He walked into the first floor.

A massive space with a ten-meter ceiling.

The main engine assembly was running with a low hum in the back.

The cold storage cluster was on the left.

The material storage area was on the right.

Clean, spacious, warm.

Twenty degrees.

"Brother Lu Chen."

Lin Xiao's voice echoed in the ten-meter-high space.

"Welcome."

Lu Chen stood next to the elevator entrance.

Lin Xiao walked over.

The distance between the two shortened from ten meters to two meters.

"This is your lv.3 fortress?"

"Yes."

"Two hundred meters long?"

"Two hundred and six."

"Two times bigger than the iron wall?"

"More than two times."

Lin Xiao looked up at the ceiling.

Neatly welded I-beam support beams were on the ten-meter-high ceiling.

LED lights were evenly distributed.

The light was bright and steady.

"Yesterday, this was still a small vehicle twenty meters long."

"Yes."

"Today, it is a two-hundred-meter fortress."

"Yes."

Lin Xiao raised a tin box in his hand to his chest.

The box was forty centimeters long, thirty centimeters wide, and fifteen centimeters high.

The surface of the tin was severely worn, with collision marks on the four corners, and the latch was already open.

"Eleven pre-civilization technical documents."

"They are all inside."

"The collection of the Black Rock City-State over one hundred and thirty-seven years."

"They started saving them back in my grandfather's generation."

"They are all yours."

Lin Xiao handed the box over.

Lu Chen took it.

Heavy.

About seven kilograms.

"Thanks."

"You're welcome."

Lin Xiao's voice became half a notch heavier, "Exchanged for the lives of thirty thousand people."
