When Lin Yi woke up again, the bright white light above him made him squint slightly. His head was still throbbing, but the flood of memories imprinted from the future's knowledge had begun to settle, as if buried deep within the recesses of his mind.
The environment around him was both familiar and unfamiliar—a hospital ward. But unlike the ruins he had just witnessed, this place was clean and orderly, with a potted green plant in the corner. It was clear that this was no longer the world of despair he had just escaped from.
"Yi'er! You're awake!"
A gentle voice rang out. Lin Yi turned his head and saw his mother sitting by the bed. Her face was full of worry, but her eyes carried more relief than fear. She held his hand gently, as if checking his temperature.
"Mom…" Lin Yi's voice was hoarse. The warmth of the present contrasted sharply with the cold, ruined future, making him momentarily dazed.
"You little brat."
A deep, stern voice came from the doorway.
Lin Yi looked up to see his father standing there. The towering man exuded the aura of a soldier, his right arm, a mechanical prosthetic, gleaming under the light. That metallic arm was a mark of countless battles and sacrifices. Ever since childhood, Lin Yi had admired his father's unwavering strength.
His father walked over to the bedside, scanning Lin Yi with sharp eyes before speaking in a firm, steady tone:
"What the hell did you do this time? The doctor said you collapsed due to malnutrition and overexertion. What exactly have you been up to?"
Lin Yi opened his mouth but hesitated. He couldn't exactly tell his father that he had just traveled to a post-apocalyptic future, witnessed the downfall of humanity, and returned with the key to survival.
"Old Lin, Yi'er just woke up. Don't scare him." His mother gently tugged on his father's sleeve, her voice full of concern. "He's still weak. We can ask later when he's feeling better."
Lin Yi's father huffed, his expression still strict, but his stance softened slightly. He sighed and raised his mechanical arm slightly, as if wanting to pat Lin Yi on the shoulder—but then hesitated, fearing his grip would be too strong. Instead, he placed his hand on the bedside.
"Stop making us worry." His father's voice remained firm. "And quit getting yourself into these messes."
"Dad, Mom…" Lin Yi murmured, glancing between them. A lump formed in his throat. Returning to this reality, seeing his parents alive and well, their concern for him so tangible—it was almost too much to process.
His mother gently squeezed his hand, her tone soft. "Yi'er, no matter what's going on, your health is most important. If something happens, tell us. Don't keep everything bottled up inside, okay?"
Lin Yi nodded slowly. His throat felt dry, and he could only hum softly in response.
Just then, his father's eyes narrowed slightly, his sharp gaze locking onto Lin Yi's face.
"You're hiding something." His father's voice was laced with suspicion.
Lin Yi's heart skipped a beat.
Forcing himself to remain calm, he quickly shook his head. "No, I think I was just too exhausted… Schoolwork and training have been a lot recently."
His father didn't look convinced. His sharp eyes studied Lin Yi as if analyzing a suspect on the battlefield, but eventually, he let it go.
"Stop making excuses. Remember, in our family, we face things head-on." His father's voice carried the weight of discipline and experience.
Sensing the growing tension, Lin Yi's mother gently nudged her husband. "Alright, enough. Yi'er just woke up, don't stress him out. Why don't you go buy some food? The doctor said he needs proper nutrition."
Lin Yi's father glanced at his wife, then at his son, before finally sighing and heading towards the door. His posture remained strong, but there was a hint of heaviness in his steps.
Once the room was empty except for them, Lin Yi's mother sighed softly and turned to him with a gentle, knowing look.
"Yi'er, if there's anything you want to say… you can tell me." Her voice was filled with worry.
Lin Yi looked into her warm, understanding eyes, feeling a deep sense of comfort. But in the end, he didn't reveal the full truth. He merely smiled faintly and whispered:
"I'm fine, Mom. Just too tired."
His mother nodded slightly, not pushing any further. She simply ran her hand gently over his forehead, just like she did when he was a child, trying to lull him to sleep.
Lying there, feeling his parents' warmth, Lin Yi strengthened his resolve. He couldn't let them worry unnecessarily. And more importantly—he had to act before the future's tragedy became reality.
-------------
Lin Yi stared at the ceiling, sorting through the knowledge embedded in his mind.
Finally, he understood why the black box had warned him not to trust the Intelligence Brain.
It wasn't because the Intelligence Brain itself was evil or plotting against humanity.
Rather, the Intelligence Brain was a system fundamentally reliant on data storage and transmission—meaning it could be hacked, manipulated, or exploited by external forces. In the post-apocalyptic future, the alien fleet had likely used advanced cyber warfare to turn the Intelligence Brain against humanity.
But that was before Wang Yanfei grew strong enough to challenge the world's top forces alone. Now, Lin Yi knew that with the right preparations, this scenario could be prevented.
"Since the Intelligence Brain itself isn't inherently compromised, I can use it to accelerate preparations."
His decision was made. He would reveal parts of the future—but not Wang Yanfei's fate.
He would only disclose what was necessary to help humanity survive.
"Xiao Yin, are you online?" Lin Yi spoke softly, his tone carrying a newfound weight.
A calm, synthetic voice replied instantly:
"Xiao Yin is online. How may I assist you?"
Lin Yi hesitated for a moment, then said firmly:
"Record a technology report. Prepare for transmission."
"Please specify the contents."
Lin Yi took a deep breath and began speaking:
"Fundamental Theory of Human Enhancement Technology."
"Utilizing specialized pharmaceuticals combined with genetic repair, this technology enhances overall human capabilities—including strength, endurance, and recovery. The core mechanism involves targeted cell regeneration and gene expression adjustments to amplify physical potential while minimizing side effects."
He paused briefly before continuing:
"The key lies in the synergy between two molecular compounds. The first, 'Recombinant Peptide,' stimulates cellular proliferation. The second, 'Stability Factor,' mitigates genetic mutation risks. Under controlled temperatures and catalytic conditions, they fuse into a highly effective enhancement formula."
Xiao Yin's synthetic voice responded: "Application range?"
Lin Yi answered without hesitation:
"Primary use for combat personnel, extreme environment operatives, and high-intensity recovery scenarios. Coupled with genetic diagnostics, optimization can reach peak efficiency."
Xiao Yin paused for a moment, then asked: "Would you like this data encrypted before transmission?"
Lin Yi nodded. "Encrypt and send to the nearest Intelligence Brain node."
He watched the progress bar move steadily, his heart pounding.
If the data was successfully uploaded, it would immediately attract high-level attention.
"Transmission complete. Data encrypted and sent." Xiao Yin's voice remained neutral.
Lin Yi counted the seconds, expecting a response.
Suddenly, Xiao Yin's tone shifted slightly, carrying an unusual gravity:
"Local Intelligence Brain Node D-07 has detected the transmission. Establishing direct connection."
The screen flickered.
A deeper, colder mechanical voice emerged:
"East Country Intelligence Brain D-07 connected. Analyzing transmitted technology. Identity verification required."
Lin Yi's heart raced slightly, but his voice remained calm and firm:
"I am Lin Yi. This technology is my contribution."
A brief silence.
Then, the Intelligence Brain responded:
"Lin Yi, your data submission has been flagged as high-priority. Explain its origin and context."
Lin Yi exhaled slowly. He knew he couldn't reveal everything—but he also knew he couldn't hold back too much.
So, he told them the truth.
Or at least, part of it.
