Use-Disuse Evolution

"Baby, you must be starving. Come, Mommy will feed you."

A gentle woman's voice rang out.

The next moment, Lin Zichen felt something soft shoved into his mouth, and he instinctively began to suckle.

Having been born just over a month ago, he had a sliver of consciousness, but not much.

He only knew to cry when hungry and sleep when full.

His thoughts were essentially a chaotic void, lacking the capacity for complete reasoning.

[Energy +1]

[Energy +1]

[Energy +1]

[...]

As he consumed more breast milk, Lin Zichen suddenly felt his head itching, as if his brain were finally growing.

Immediately after, a character panel slowly manifested from the void.

[Name: Lin Zichen]

[Age: 33 days]

[Biological Rank: ordinary (Tier 1)]

[Biological Attribute: None]

Looking at the panel in the void, Lin Zichen finally realized one thing.

He had transmigrated.

He had transmigrated into a newborn whose brain had not yet fully developed.

And he possessed a golden finger.

After thinking about this for only a short while, Lin Zichen felt exhausted and soon drifted off to sleep.

"The little one falls asleep the moment he's full; it's truly enviable. Mommy has lost quite a bit of sleep taking care of you."

The woman looked at the sleeping Lin Zichen in her arms, murmuring with a smile full of love.

In the blink of an eye, two more months passed.

After these days of development, Lin Zichen's consciousness had become much clearer, and he possessed a relatively complete ability to think.

With a functioning brain, the first thing he did was study his golden finger.

He learned that it was an achievement-based system, and he had already triggered the first achievement task.

[Achievement: Accumulate 10,000 leg kicks]

[reward: Obtain Biological Attribute—Use-Disuse Evolution]

[Accumulated leg kicks: 1024/10000]

Lin Zichen glanced at the progress bar and silently lay in his crib, kicking his legs.

"Baby, kicking your legs again?"

"When did you wake up?"

"You don't cry or fuss when you wake up; you really are a good baby who makes things easy for Mommy."

His mother, Zhang Wanxin, entered the room and saw Lin Zichen lying in his crib, quietly kicking his legs, a gratified smile appearing on her face.

Seeing this, Lin Zichen smiled back at her in response.

Soon, his father, Lin Yansheng, also entered, saying with a face full of expectation:

"The little guy is so lively and active; he clearly has great physical talent. In the future, he will surely be able to become a high and mighty Gene Fusionist, or at the very least, a Mechanical Cyborg."

Gene Fusionist?

Mechanical Cyborg?

What are these things?

Lin Zichen frowned slightly, realizing that this world seemed quite different from his previous life.

Without realizing it, another month passed.

Over the past month, Lin Zichen had kicked his legs an average of 300 times a day, finally accumulating the full ten thousand.

[Accumulated 10,000 leg kicks, achieved]

[Obtained Biological Attribute: Use-Disuse Evolution]

[Use-Disuse Evolution: As long as you continuously exercise the same body part, that part can evolve and strengthen infinitely, though it cannot break the limits of carbon-based life.]

After reading the content, Lin Zichen immediately began kicking his legs with practiced ease, unable to wait to experience the effects of Use-Disuse Evolution.

[You are performing leg presses, Blood Qi +1, leg muscle strength +1, leg press proficiency +1]

The moment the notification appeared, Lin Zichen clearly felt a surge of strength in his legs.

Feeling slightly invigorated by this, he put even more effort into his leg presses.

When he grew tired of that, he switched to swinging his arms.

[You are waving your arms, Blood Qi +1, arm muscle strength +1, arm waving proficiency +1]

Once his arms were exhausted, he switched to twisting his body, engaging every muscle to achieve a full-body workout.

Just like that, nearly a week passed.

Lin Zichen's body had grown much stronger; he could now sit up in his crib on his own, no longer forced to lie there staring at the ceiling like before.

Under normal circumstances, newborns usually take about seven months before they can sit up by themselves.

Yet he was only four months old and had already achieved this.

Over the next half-month.

Lin Zichen targeted his limbs for exercise and quickly mastered the technique of crawling.

[You are crawling, Blood Qi +1, body coordination +1, crawling proficiency +1]

To avoid appearing too heaven-defying or inhuman, which might invite unnecessary trouble, Lin Zichen did not expose his ability to crawl in front of his parents.

He only slipped out of bed to crawl and exercise on the floor once his parents were asleep at night.

He crawled faster than the cockroaches in the room, darting back and forth in the dark corners.

A month later, Lin Zichen learned to walk.

[You are walking, Blood Qi +1, body coordination +1, walking proficiency +1]

At the same time, by watching the news on television, he gained a preliminary understanding of the world he was in.

He was still on Earth, but the planet had mutated, and many terrifying, unknown creatures had appeared.

These unknown creatures were collectively known as Exotic Beasts.

To combat the Exotic Beasts, humanity had spent decades carving out two paths.

First, genetic modification: fusing with the genes of Exotic Beasts to gain some of their abilities, using magic to defeat magic.

Second, flesh is weak, so ascend through machinery, using technology to defeat the Exotic Beasts.

These two paths corresponded to the Gene Fusionists and the Mechanical Cyborgs.

So this world is actually this dangerous. I hope I can grow up safely, keep a low profile while I evolve, and avoid any accidents, Lin Zichen hoped inwardly.

Half a month later.

Lin Zichen's walking became increasingly proficient; he estimated it wouldn't be long before he learned to run.

Most newborns don't learn to walk until they are about a year old.

Yet he was only six months old and already nearing the ability to run—it was practically a dimensional strike.

In the blink of an eye, I'm over six months old. I can start crawling in front of my parents now; no need to keep hiding it.

With that thought in mind, Lin Zichen soon demonstrated his crawling skills before his parents.

"Honey, look! Chenchen can crawl, and he's so fast!" Zhang Wanxin exclaimed in surprise.

Lin Yansheng was equally shocked, but more than that, he was thrilled and excited. His face beamed with a smile as he said, "He's only six months old and he can already crawl, and so fast at that! Our son is a genius!"

"Ding-dong!"

Suddenly, the doorbell rang.

Lin Yansheng went to check and found that the neighbors who had moved in a few days ago were there to pay a visit, carrying gifts.

Hearing the commotion at the door, Zhang Wanxin picked up Lin Zichen, who had been crawling around on the floor, and went over to meet the new neighbors.

The visitors were a young couple.

The man was holding gifts, and the woman was cradling a baby girl in her arms.

Lin Yansheng accepted the gifts and warmly invited the young couple inside to sit down.

Soon, the two families were seated in the living room, drinking tea and chatting happily.

After chatting for a while, they discovered that the two children were born only one day apart, which was quite a coincidence.

Lin Zichen sat on Zhang Wanxin's lap, curiously sizing up the baby girl opposite him who had been born a day later than he was.

Her eyes were large and watery, making her look incredibly adorable.

The baby girl was also curiously sizing him up, and every time she made eye contact with him, she would smile, her expression exceptionally bright.

After listening to the adults talk for a while, Lin Zichen felt bored, so he struggled in Zhang Wanxin's arms, signaling for his mother to put him down.

Understanding his intent, Zhang Wanxin laughed and remarked about how active he was before setting him on the floor.

Once on the ground, Lin Zichen quickly began crawling around to exercise his body.

[You have crawled 10 meters, Blood Qi +1, physical coordination +1, crawling proficiency +1]

[You have crawled 100 meters, Blood Qi +10, physical coordination +10, crawling proficiency +10]

[You have crawled 500 meters...]

Lin Zichen crawled very quickly, darting around the room like a little mouse.

Seeing this scene, the baby girl's mother was quite astonished and said, "How impressive! Your baby has already learned to crawl so quickly; my Hanhan has only just learned to sit up on her own."

Seeing the surprise on her face, Lin Yansheng and Zhang Wanxin both felt a small sense of satisfaction, thinking to themselves that having a genius son was truly great.
