1. Use It or Lose It
"Baby, you must be starving. Here, let Mommy feed you some milk."
A gentle female voice spoke up.
The next moment, Lin Zichen felt something soft being placed in his mouth, and he instinctively began to suck.
Being just over a month old, his mind had some awareness, but not much.
All he knew was to cry when hungry and sleep when full.
His thoughts were mostly chaotic, without the capacity for complete reasoning.
[Energy +1]
[Energy +1]
[Energy +1]
[...]
As he sucked more and more breast milk, Lin Zichen suddenly felt his head itch, as if his brain was starting to grow.
Following that, a character panel slowly emerged from the void.
[Name: Lin Zichen]
[Age: 33 days]
[Biological Level: Normal (Tier 1)]
[Biometric Attributes: None]
Looking at the panel in the void, Lin Zichen finally realized something.
He had transmigrated.
He had transmigrated into an infant whose brain hadn't fully developed yet.
And he had acquired a golden finger.
After pondering these things for a while, Lin Zichen felt very tired and soon fell into a deep sleep.
"This little guy falls asleep as soon as he's full, truly enviable. Mommy has had many sleepless nights taking care of you," the woman murmured lovingly as she looked at Lin Zichen sleeping peacefully in her arms.
...
In the blink of an eye, over two months had passed.
Over these days, Lin Zichen's consciousness had become much clearer and he had a more complete ability to think.
The first thing he did with his new brain was to study his golden finger.
He learned that it was an achievement-oriented golden finger and had triggered his first achievement task.
[Achievement: Accumulate 10,000 leg kicks]
[Reward: Gain Biometric Attribute—Use It or Lose It]
[Total leg kicks: 1024/10000]
Lin Zichen glanced at the progress bar and quietly lay in his crib, kicking his legs.
"Baby, kicking your legs again."
"When did you wake up?"
"You woke up without crying or fussing, truly a baby that gives Mommy peace of mind."
Mother Zhang Wanxin entered the room, saw Lin Zichen lying quietly in his crib kicking his legs, and her face lit up with a relieved smile.
Lin Zichen smiled back at her.
Soon, his father Lin Yansheng also came in, full of expectation:
"Little guy is so lively, you can tell he has a natural talent for physical ability. Surely he'll grow up to be a lofty Genetic Integrator or, at the very least, a Mechanically Modified Human."
Genetic Integrator?
Mechanically Modified Human?
What are these things?
Lin Zichen's brow furrowed slightly, realizing that this world was quite different from his previous one.
...
Before he knew it, another month had passed.
In the last month, Lin Zichen managed to kick an average of 300 times a day and finally completed the 10,000 kicks.
[Accumulated 10,000 kicks, achievement reached]
[Gained Biometric Attribute: Use It or Lose It]
[Use It or Lose It: As long as you continuously and relentlessly train the same body part, that part can evolve and strengthen indefinitely, though it cannot break the limits of carbon-based lifeforms]
After reading the content, Lin Zichen immediately started kicking his legs, eager to experience the effects of Use It or Lose It.
[You are kicking, Qi-Blood +1, leg muscle strength +1, leg kicking proficiency +1]
The moment the notification appeared, Lin Zichen distinctly felt a surge of strength in his legs.
Excited, he kicked even harder.
When tired of kicking, he switched to waving his arms.
[You are waving, Qi-Blood +1, arm muscle strength +1, arm waving proficiency +1]
When his arms also became fatigued, he switched to twisting his body to get all his muscles moving and to achieve a full-body workout.
Thus, a week passed.
Lin Zichen's body had grown much stronger. He could now sit up on his own in the crib, no longer having to lie in bed and stare at the ceiling as before.
Under normal circumstances, infants usually manage to sit up on their own at around seven months.
Yet here he was, just over four months old, already capable of doing so.
...
In the following half month,
Lin Zichen specifically exercised his limbs and quickly mastered crawling.
[You are crawling, Qi-Blood +1, body coordination +1, crawling proficiency +1]
To avoid seeming too supernatural, too contrary to human nature, and thereby attracting unnecessary trouble,
Lin Zichen did not reveal his ability to crawl in front of his parents.
He only sneakily got out of bed and crawled on the floor when his parents were asleep at night.
Crawling faster than the cockroaches in the house.
Rapidly crawling back and forth in the dark corners.
...
A month later, Lin Zichen also learned how to walk.
[You are walking, Qi-Blood +1, body coordination +1, walking proficiency +1]
Meanwhile, he gathered a preliminary understanding of his world through watching the news on TV.
Humans were still on Earth, but Earth had mutated, spawning many terrifying unknown creatures.
These unknown creatures were collectively called Exotic Beasts.
To counter the Exotic Beasts, humanity had developed two paths over decades.
One, gene modification, integrating Exotic Beast genes to acquire some of their abilities, using magic to defeat magic.
Two, the weakness of flesh and bone, ascension through technology, using technology to conquer the Exotic Beasts.
And these two paths corresponded to the Genetic Integrators and the Mechanically Modified Humans.
"This world is so dangerous, I hope I can grow up safely, focus on evolving without any accidents,"
Lin Zichen hoped to himself.
...
Half a month later,
Lin Zichen's walking grew more proficient, and it seemed he would soon learn to run.
Most infants tend to learn walking around one year of age.
Yet here he was, only six months old and almost ready to run, indeed crushing dimensions.
"In the blink of an eye, I'm over six months old. I can crawl in front of my parents now, no need to hide anymore,"
he thought to himself.
Soon, Lin Zichen was showing off his crawling prowess in front of his parents.
"Honey, look, Chen Chen can crawl now, and he's so fast!"
Zhang Wanxin exclaimed in surprise.
Lin Yansheng was equally surprised, but more excited and thrilled, his face covered in smiles, "Just over six months old and he can crawl, and so fast, our son is a genius!"
"Ding dong!"
Suddenly, the doorbell at home rang.
Lin Yansheng went to check and found it was the neighbors who had just moved in a few days ago, coming over with a gift to visit.
Hearing the noise at the door, Zhang Wanxin picked up Lin Zichen, who was crawling around on the floor, and went to meet the new neighbors as well.
The visitors were a young couple.
The man was holding a gift while the woman cradled a baby girl in her arms.
Lin Yansheng accepted the gift and warmly invited the young couple to come in and sit.
Soon, both families sat down in the house, drinking tea and chatting merrily.
During the chat, they discovered that their children were born just a day apart, quite serendipitously.
Lin Zichen sat on Zhang Wanxin's lap, curiously sizing up the baby girl who was born a day later than he was.
Her eyes were big, watery, and very cute.
The baby girl was also curiously looking at him, bursting into a radiant smile whenever their eyes met.
Finding the adults' conversation boring, Lin Zichen struggled a bit in Zhang Wanxin's embrace, prompting his mother to let him down.
Zhang Wanxin got the hint, smiled, and said he was really active before putting him down on the floor.
Once on the floor, Lin Zichen quickly began crawling around, exercising his body.
[You crawled 10 meters, Qi-Blood +1, body coordination +1, crawling proficiency +1]
[You crawled 100 meters, Qi-Blood +10, body coordination +10, crawling proficiency +10]
[You crawled 500 meters...]
Lin Zichen crawled so fast, darting around the room like a mouse.
The baby girl's mother, witnessing this, was amazed, "That's incredible, your baby learned to crawl so quickly. My Han Han just learned to sit by herself."
Seeing the surprise on the other's face, Lin Yansheng and Zhang Wanxin felt a bit smug, thinking it was great to have a genius son.
