255: Chapter 255 Three Hundred Years Old! Su Che Personally Experiences Level Three Civilization Medical Aesthetic Transformation!

There was no title on the door panel. Only a countdown and a task description.

[Unlock Task: Within the allotted time, use the components provided in the chamber to assemble and calibrate a complete magnetic levitation cargo transport track. The transport vehicle must complete a collision-free run from the starting point to the destination on the track, with an error margin not exceeding 0.01 millimeters.]

Automation Expert Jiang Yi stood in the chamber behind the door, which was piled high with components. He looked at the magnetic levitation modules, track connectors, sensor arrays, and transport vehicle chassis scattered all over the floor, and rubbed his hands together.

"This isn't an exam; this is real work."

Friedman divided the twenty people into four groups: the track laying group, the sensor calibration group, the transport vehicle assembly group, and the system debugging group. Automation Expert Jiang Yi was responsible for overall coordination.

The precision required for laying the magnetic levitation track was extremely high; the splicing error for each module segment could not exceed 0.005 millimeters. The members of the third group lay on the ground, adjusting it section by section using the precision calibration tools provided by Kairos.

The sensor array was even more troublesome. Each sensor node had to be calibrated individually. With over a hundred nodes, a single round of calibration took the better part of a day.

The transport vehicle's magnetic levitation chassis required manual balancing. Automation Expert Jiang Yi crouched beside the vehicle, tightening bolts with a wrench for three hours.

On the fifth day, the final step—system debugging—took place. The transport vehicle started running on the track, completing a collision-free journey from the starting point to the destination. The final data popped up on the terminal. Error: 0.007 millimeters.

[Task completed, unlock successful.] [Shipborne Automated Cargo Transport System] Magnetic levitation tracks, robotic arm clusters, and unmanned transport vehicles, operating twenty-four hours a day without interruption.

Automation Expert Jiang Yi stood next to the transport vehicle and patted the roof a few times. "Think of how much manpower this thing will save for the entire ship's logistics in the future."

For the twenty-ninth door, Patrick led the fourth group for six days. It was the Shipborne Main Propulsion System Auxiliary Power Compartment. They added a set of backup 'legs' to the mothership, fully upgrading its navigational maneuverability and emergency braking.

Academician Zhong led the fifth group for six days to unlock the thirtieth door. It was the Shipborne Full-Spectrum Fire and Disaster Response System. Carol Hunter stood before the system console, looking at the disaster monitoring network that covered the entire ship on the screen.

"Full-area automatic detection terminals, unmanned response robots; it can respond to any disaster within thirty seconds." She flipped through a menu layer. "Fires, chemical leaks, radiation contamination, biological leaks—it can handle them all."

Ye Zhiqiu led the first group for five days to unlock the thirty-first door. It was the Shipborne Planetary Atmosphere and Geological Exploration System. Friedman, as an astrophysics expert, specifically ran over.

He and Gary Nolan stood before the exploration system terminal, looking at the parameters of the deep space exploration radar and spectrometer, and touched the terminal's casing. "Atmospheric composition, geological structure, mineral resources, habitability assessment, life sign detection—the full suite of functions."

Gary Nolan pulled up the planetary surface scanning module. A 3D model of an Earth-like planet appeared on the holographic screen, with surface rock composition and mineral distribution clearly marked. "This thing will come in handy when we land on planets in the future." Gary Nolan patted Friedman on the back.

In one month, five doors were all successfully unlocked without triggering a single penalty mechanism. Su Che stood before the holographic star map in the main control hall, reviewing the progress of the past month in his mind.

The mothership's unlock progress had reached thirty-one percent. With sixty-nine doors remaining, at the current speed, it would take several more months. But at least, they had some decent, useful functions now.

The communicator rang. It was Liu Nanshan's voice. "Chief Engineer Su, do you have a moment?"

Su Che glanced at the time. "Speak."

"The three of us—myself, Chen Junhong, and Lillian Brown—have become fully proficient in operating the medical chamber." Liu Nanshan's tone was steady. "Cellular-level damage repair, genetic defect correction, complete limb regeneration, brain death resuscitation—we have performed at least fifty simulated operations on all functional modules."

"For the project on biological anti-aging and life extension, we have also performed complete parameter deductions and animal model verifications." "Chief Engineer Su, we can begin."

"How confident are you?" Su Che asked. "One hundred percent." Liu Nanshan answered decisively. "This is mass-produced civilian technology from a Level 3 Civilization; the parameters are all ready-made, and we are merely the executors." "I stake my life on it; there will be no errors," he emphasized at the end.

Su Che turned off the communicator. He stood before the holographic star map, looking at the dense clusters of star points. Three hundred years.

From Su Family Village to lunar orbit, from hand-crafting EMP grenades to a Level 3 Civilization mothership, this year had passed too quickly—so quickly that he hadn't had time to think about the future. If he could really live for three hundred years, this game had only just begun.

Keira walked over from the other end of the corridor. "Lord Chief, about the matter with Liu Nanshan and the others?"

"Yes." Su Che turned away from the star map. "Keira, what is the usual procedure for Kairos people when performing biological anti-aging and life extension?"

"Every Kairos citizen undergoes basic biological anti-aging and life extension after birth, with a minimum starting lifespan of one thousand Earth years." "What does three hundred years mean to you?" "Underage."

Su Che grinned. He picked up the communicator and dialed back to Liu Nanshan's channel. "Old Liu." "I'm here." "Then I will be the first human to possess a three-hundred-year lifespan." The communication cut off. "Let's go, we're heading to the medical chamber."

The lighting in the medical chamber area was cold white, illuminating the corridor as brightly as an operating room. When Su Che walked in with Keira, Liu Nanshan, Chen Junhong, and Lillian Brown were already standing beside the mutton-fat jade-colored hibernation chamber in the center.

The three of them had all changed into white operation suits, each holding a transparent data pad with dense parameters. "Chief Engineer Su, please lie down here." Liu Nanshan patted the edge of the hibernation chamber.

Su Che took off his jacket and handed it to Keira. Wearing a black long-sleeved T-shirt, he turned and sat on the edge of the chamber. Before lying down, he turned his head to look at Liu Nanshan. "Old Liu, you said you staked your life on it earlier; I took you seriously."

Liu Nanshan finished checking the last line of parameters on the data pad and looked up. "I took it seriously, too."

On the other side of the chamber, Chen Junhong attached three biological sensor patches to Su Che's left chest, right neck, and the inner side of his left wrist. The moment the patches touched his skin, a slight chill seeped through the fabric.

"Chief Engineer Su, the whole process will take about eight to ten hours. During this time, you will enter a state of deep sleep and won't feel any discomfort." Chen Junhong said this while adjusting parameters on the operation console.

Lillian Brown stood before the control panel, her ten fingers sliding rapidly across the touchscreen, bringing up the complete flow chart for the biological anti-aging and life extension procedure.

"Mr. Su, I need to confirm, you currently have no history of drug allergies, implants, or chronic diseases, is that correct?" "None." Su Che lay flat, his head sinking into the soft padding inside the chamber.

"Very good." Lillian Brown pushed the flow chart to Liu Nanshan and Chen Junhong's data pads. "The procedure is divided into three stages. The first stage is cellular-level scanning and baseline modeling, which will take about one and a half hours." "The second stage is telomere repair and genetic defect correction; this is the core stage and will take the longest, about five to six hours." "The third stage is overall body optimization and awakening, about two hours."

Liu Nanshan went through the flow chart from beginning to end and marked three key nodes. "Begin."

The chamber lid closed from both sides, and the translucent material turned the outside light into a blurry halo. Su Che heard a very low-frequency hum conducting through the chamber wall, as if something was resonating deep within his bones. Then, his consciousness faded.

Liu Nanshan stared at the real-time data on the operation console, where a 3D model of Su Che's body was being constructed layer by layer on the holographic screen. From skin to muscle, from bone to blood vessel, the structure of every cell was being scanned and recorded.

"Average cellular telomere length... is sixty-two percent below the normal value." Chen Junhong read out the data and frowned.

"Long-term high-intensity work, combined with the latent damage caused to the body during the previous system point clearing, makes this value expected." Liu Nanshan made a note on the data pad.

Lillian Brown adjusted the repair parameters for the second stage on the control panel. "Set the telomere extension coefficient to 1.4, and run it in synchronization with the genetic defect correction module."

"1.4?" Chen Junhong took a look. "The default value for Kairos is 1.2."

"Su Che has a solid physical foundation; he can handle a coefficient of 1.4, and the results will be more thorough." Lillian Brown's tone was certain. "I have performed over three hundred simulation deductions, and this parameter is the optimal solution." Liu Nanshan nodded. "Execute at 1.4."

Three hours later. On the holographic screen, the 3D model of Su Che's cells began to change. The red telomere-marked areas were extending bit by bit, and those dark patches representing genetic defects were being covered by green highlighted markers.

Liu Nanshan stood before the operation console, not moving an inch for a second. His data pad recorded over two thousand real-time parameters, refreshing every few seconds. Chen Junhong handed him a glass of water from the side. "Drink some water, Old Liu."

Liu Nanshan took it and drank a sip, his eyes never leaving the screen. "Do you know how many terminal patients I've seen in my forty years of practicing medicine?" "Too many to count." "If only this thing had appeared fifty years earlier..." Liu Nanshan didn't finish his sentence.

The fifth hour. Telomere repair entered the final phase, and the genetic defect correction module began processing the last batch of markers. Lillian Brown brought up the body optimization parameters for the third stage ahead of time.

"Skin texture optimization, muscle fiber density adjustment, bone microstructure reinforcement, cardiovascular system cleaning, nervous system conduction efficiency improvement... a total of seventeen sub-projects." "All of them?" Chen Junhong asked. "All of them." Lillian Brown did not hesitate. "Give Su Che a fully equipped three-hundred-year lifespan."

Liu Nanshan checked the final confirmation line on the flow chart. "Execute." Inside the chamber, a faint golden halo shimmered on the surface of Su Che's body; that was the nano-scale repair units at work. From bones to skin, from blood vessels to nerves, every cell was being recalibrated.

The next morning. The lighting in the medical chamber area switched from cold white to warm yellow, simulating a sunrise. Su Che opened his eyes. The first feeling was lightness. It wasn't the airy feeling of not being fully awake; it was the lightness of having shed something heavy from every muscle and every bone in his body.

The chamber lid slid open, and the morning light-like illumination poured in. Su Che sat up and flexed his fingers. There was no sound from his joints, no stiffness, no friction. He looked down at his hand; the skin on the back of his hand was a grade finer than yesterday, and the few small scars left from previous training were all gone.

"How does it feel?" Liu Nanshan stood by the chamber, holding the data pad. Su Che stood up from the chamber, his feet touching the ground, with no discomfort in his knees. He twisted his waist, turned his neck, and did a few squats. "It feels like I've swapped in a new engine."

"According to the data, your cellular telomere length has recovered to one hundred and forty percent of the normal value." Chen Junhong read the data from the side. "All latent genetic defects have been cleared, muscle fiber density has increased by fifteen percent, bone density has increased by eight percent, and all micro-plaques in the cardiovascular system have been cleaned out."

Lillian Brown generated the final report and pushed it to Su Che's communicator. "Mr. Su, your biological age is now twenty-two, with a theoretical lifespan of three hundred years."

Su Che looked down at his hand again. He clenched his fist, and his knuckles made a crisp sound. Twenty-two. When he was persuaded to withdraw from the National Defense University and return to the village a year ago, he was exactly twenty-two.

"Worth it." Su Che took his jacket from Keira and walked out while putting it on. "Old Liu, solidify this procedure; from now on, everyone will follow this standard." "Understood." Liu Nanshan put away the data pad and exchanged a glance with Chen Junhong. There was something in both of their eyes that was completely different from when they had first stepped into this door. Back then, it was shock and disbelief. Now, it was certainty.

Su Che walked out of the medical chamber area and headed along the corridor toward the main control hall. The communicator rang; it was Keira calling. "Lord Chief, a penalty mechanism has triggered again with Su Wanxing's second group; the medical chamber will come in handy this time." Su Che's footsteps paused. "I'm coming right over."
