2: biology

Just as Han Chengyu was immersed in the armor design, sketching the curves of the pauldrons and the outline of the helmet, a series of approaching footsteps interrupted his thoughts.

Through his external sensors, he saw a pair of police leather shoes—not particularly shiny and even stained with a bit of mud—stop in front of him.

Then, a young face, still slightly childish but with a serious set to his brow, leaned down, looking curiously at the corner where he was.

"Huh? What's this?"

The young policeman muttered as he crouched down and reached out without hesitation to pick Han Chengyu—this quite heavy "watch"—up from the damp ground. His palm was warm, carrying the vitality unique to young people.

"The craftsmanship is really good; it looks like a high-end toy." The young policeman rubbed his finger against the cold metal of the watch's body and the ring of eerie blue light, his eyes showing the fondness a boy has when seeing a favorite model. "Who threw something so cool here?"

"Xiao Lu, what are you dawdling for? What did you find?" A slightly gruff and tired voice came over. Another older policeman, with a weathered face and a meticulously worn uniform, walked up.

The young policeman, called "Xiao Lu," immediately held out the "watch" like a treasure. "Uncle Li, look! I found a pretty cool toy. Doesn't it look like those hero transformation devices from the Tokusatsu shows we watched as kids?"

The old policeman—Uncle Li—took the "watch," weighed it in his hand, and looked at it carefully in the dim light, frowning slightly. "Tsk, it doesn't look cheap. Probably lost by some youngster. Keep it for now, and check if anyone reports it as lost when we get back."

He handed the "watch" back to the young policeman and gave him a playful slap on the back of the head. "Still dreaming of heroes? Focus on patrolling your district first! Let's go, we'll head back to the station after checking this area."

"Alright!" The young policeman—Lu Jianchuan, whose name Han Chengyu had just learned through a System scan—carefully tucked the "watch" into the pocket of his police jacket.

In an instant, Han Chengyu's "vision" was shrouded in darkness, leaving only the faint sound of fabric rubbing and the steady, powerful heartbeat of the young policeman through his clothes.

[High-affinity life form contact detected. Initiating basic scan...]

[Scan complete. Target: Lu Jianchuan, Male, 23 years old.]

[Internal 'Primordial Evolution Factor (EVO)' concentration: 0.038%.]

[Status: Dominant potential individual. Meets Elementary binding standards. Bind as 'Aptitude Holder'?]

The System's cold prompt sounded in Han Chengyu's consciousness.

"'Primordial Evolution Factor'? What's that?" Han Chengyu immediately followed up. The name sounded very unusual.

[This is the underlying logic and source of power for all supernatural phenomena in this world.] The System began to explain, its tone like a scientific report.

[It exists deep within the genes of all life forms on this planet and is the driving source of life's initial evolution. In the vast majority of life, the factor concentration is lower than one in ten thousand, remaining in a 'recessive' state and unable to be activated throughout their lives.]

Han Chengyu immediately thought of his bizarre car accident and Transmigration. "Then I..."

[Your case is an exception, a product of cross-world consciousness projection and Fusion with local Laws; this universal rule does not apply.] The System interrupted his line of thought and continued its explanation.

[A tiny minority of individuals like Lu Jianchuan have factor concentrations exceeding the activation threshold of 0.01%, making them 'dominant potential individuals.' They are the only suitable candidates who can carry your power, activate the armor, and execute the 'Stabilization' mission.]

So that was it! This young man was the first key to completing his mission!

Han Chengyu's consciousness focused on the outside world. He "listened" to Lu Jianchuan and Uncle Li chatting while they patrolled. Their conversation was nothing more than family matters and work trivia, though occasionally Lu Jianchuan would excitedly mention his original motivation for applying to the police academy, his words filled with a simple yearning for justice and hope for the future.

[Additionally, a reminder for the Contractor.] The System's voice sounded again, pulling Han Chengyu's thoughts back.

['Primordial Evolution Factor (EVO)' is not only the key to activating power but also one of the underlying logics for the manifestation of matter and energy in this world.]

"Underlying logic? What do you mean?"

[This means that whether the armor you are designing can successfully manifest, and whether its form and abilities are stable, must strictly follow the operational Laws of the evo factor.]

[Any design that violates this underlying logic will trigger errors during the physical construction process, potentially leading to a failure to manifest. Please consider this as a core criterion in your subsequent designs.]

As the System's voice faded, Han Chengyu's consciousness plunged back into the design interface filled with infinite possibilities. Recalling the countless Tokusatsu works he had seen, he began to sketch ambitiously:

A streamlined full-body suit, a majestic compound-eye helmet, cool wing structures on the pauldrons, and ideally, a set of thruster wings on the back... However, every time he finalized an idea he thought was brilliant and tried to assign energy circuits to it, a blood-red warning would pop up on the interface:

[Error: Energy conduction structure is incompatible with 'evo factor' activation patterns], [Error: Mimicry organs conflict with local life gene sequences]... "What the hell is this 'Primordial Evolution Factor' anyway?!" After experiencing the nth error, Han Chengyu felt his consciousness like a crumpled piece of scrap paper, almost going crazy. "I don't get it at all! Why does it keep erroring! This isn't scientific!"

[According to analysis, your current design focuses too much on aesthetics and fantasy concepts, lacking respect for the basic Laws of life in this world.]

The System responded matter-of-factly, [If you truly cannot balance the two, it is suggested that you delete certain parts as appropriate...]

"Delete? Impossible!" Han Chengyu immediately interrupted. "This is the romance of Tokusatsu heroes! Pauldrons, waist capes, compound eyes! Not one can be missing! Is it even Tokusatsu without them?!" He had an unusual obsession with this.

[...Understood. Then, I will provide a solution that may fundamentally resolve the issue.] The System seemed to have anticipated his reaction and seamlessly switched the topic.

"What solution?"

The next second, Han Chengyu's "vision" was flooded by a vast stream of data.

Countless books, papers, and lab reports covering biology, genetic engineering, and Materials science poured down like a waterfall. Titles ranged from "evo factor and Cellular Energy Metabolism" and "Principles of Directional Biological Tissue Strengthening" to "Correlation Between Macro-Biological Structures and Micro-Particle Activity"... It was practically a complete set of "Supernatural Biology of This World" from beginner to expert levels.

[This is the relevant knowledge I have collected and organized in this world, from introductory biology to post-doctoral levels.] The System explained calmly.

[As long as you study diligently and thoroughly understand the operational mechanisms of the 'Primordial Evolution Factor,' you will surely be able to design a successful work that both conforms to the world's Laws and retains your personal style.]

Looking at the seemingly endless ocean of knowledge, Han Chengyu's conscious form froze.
