As he grew older, Lin Zichen began to learn about his family background.

He lived in a place called Shanhai City.

Their home was a detached house in an urban village.

It was just a simple family of three, with no other relatives.

Both of his parents were web novel authors, with little social interaction, usually staying home typing at their keyboards.

Their only social activity was occasionally dining with the family of the baby girl who had recently moved in next door.

After many such meals, Lin Zichen also became familiar with the girl’s family.

He learned that the baby girl’s name was Shen Qinghan, her parents were both teachers, her mother’s name was Xu Meng and her father’s name was Shen Jianye.

Other details he did not know.

* * *

That day, Lin Zichen welcomed his second birthday.

Right after celebrating, the first thing he did was find a storage box, load it with nearly 20 kg of miscellaneous items and attempt to lift it with one hand.

The result: he easily lifted it.

‘Alright, now I’m also a nationally sensational child prodigy.’

Lin Zichen smiled.

Just then, Zhang Wanxin’s voice called from the living room, "Chenchen, little sister Hanhan came to play with you!"

Hearing this, Lin Zichen put down the box and walked slowly toward the living room.

There, he saw a beautiful young woman and a delicate, doll-like little girl.

It was Shen Qinghan and her mother.

The baby who couldn’t crawl back then had now grown into a cute twin-tailed little girl.

"Chenchen, these are some egg tarts made by Auntie Meng, it’s delicious."

Xu Meng handed over a box of egg tarts to Lin Zichen with a smile.

Lin Zichen accepted it politely, "Thank you, Auntie Meng."

That thank you made Xu Meng’s heart ache.

At the same age, Lin Zichen could already converse fluently with adults, while her own daughter Shen Qinghan often couldn’t even fully express her thoughts.

The difference was stark, making her daughter seem slow and dull.

Truly, comparisons are cruel.

After staying in the living room for a while and eating a few egg tarts, Lin Zichen quickly returned to his room to train at high intensity.

Shen Qinghan liked to be with him, so she followed into his room, curiously watching as he did endless push-ups.

"Eight, eight egg tart."

As she watched, Shen Qinghan held out an egg tart to his mouth.

Her voice was childish and unclear, pronouncing "eat" as "eight."

"No need, you eat it yourself."

"Eight, eight, it’s tasty."

Shen Qinghan insisted he eat.

Egg tarts were her favorite food and she had to share them with Lin Zichen.

With no choice, Lin Zichen stopped and ate the tart she offered.

Then he resumed his push-ups.

After a while, he felt the training wasn’t intense enough, with little improvement.

As his body grew stronger, simple exercises could no longer satisfy his need for improvement.

Looking around the room, his eyes landed on Shen Qinghan. He had her sit on his back as extra weight.

Shen Qinghan was overjoyed, clinging to him like a sloth.

While doing weighted push-ups, Lin Zichen noticed through the sensation on his back that Shen Qinghan was still wearing a thick diaper under her dress.

Already two years old and still in diapers, that was unusual.

He recalled Xu Meng complaining to Zhang Wanxin that Qinghan still liked wetting herself, so she often had to be put in diapers.

* * *

Time flew by.

Another year passed.

Lin Zichen turned three.

By then, his physique had advanced to the point where he could lift a 40 kg sack of rice with one hand.

He didn’t know how to measure that level.

But he knew that the Kyoto child prodigy he had once seen on TV was far behind.

He had been following that prodigy’s news.

The Kyoto prodigy, now four and a half, was still struggling to lift a 30 kg dumbbell with one hand.

The gap was enormous.

Lin Zichen was puzzled.

That prodigy could lift 20 kg at two years old, so why couldn’t he lift 30 kg at four and a half?

That growth curve made no sense.

He thought about it briefly, then turned his attention inward, opening his status panel.

[Name: Lin Zichen]

[Age: 3 years]

[Biological Level: Ordinary (First Tier)]

[Biological Attribute: Use It or Lose It]

His eyes focused on the Biological Level, which still showed “Ordinary First Tier.”

He could already lift 40 kg with one hand, yet still only be First Tier?

What would Second Tier be?

Beyond human limits?

Just then, Zhang Wanxin appeared and said, "Chenchen, mommy is going shopping with Auntie Meng later. Do you want to come with me, or stay home with daddy?"

"I’ll go shopping with mommy."

He answered without hesitation.

Being cooped up training every day felt suffocating, he needed a break.

* * *

When mother and son put on their shoes and went out, Shen Qinghan and her mother were already waiting outside.

Three-year-old Shen Qinghan wore a frilly dress, a pink bow hairpin and had big watery eyes, looking very cute.

"Chenchen, have a cookie."

She broke her cookie in half, giving the bigger half to Lin Zichen.

Her voice was no longer unclear, now smooth and clear.

"Thank you."

Lin Zichen accepted and ate it in one bite.

Shen Qinghan beamed with joy, still the same cheerful girl—and still the same habit, with a thick diaper under her skirt.

[You are walking, Vitality +1, Body coordination +1, Walking proficiency +1...]

On the street, Lin Zichen trained while walking, observing the surroundings.

Busy traffic, tall buildings, not much different from his previous life.

Only the architecture and transportation looked more high-tech.

A more obvious difference was the occasional Beastkin and Cyborg in the crowd.

Beastkin were warriors fused with Aberrant Beast genes, whose bodies bore beast-like traits.

Some had animal ears.

Some had wings.

Some were covered in scales, like lizardmen.

Cyborgs were mechanically modified humans, with metal parts replacing body sections, resembling Genos from One Punch Man, radiating cyberpunk style.

Both Gene Fusers and Cyborgs were rare, one could walk a long way before spotting one.

Yet they stood out, always drawing attention.
