Rainbow Kindergarten, at the school gate.

Countless children cried loudly as they looked at their parents outside the gate.

For most of them, this was their first time away from their parents, spending the day in a strange place.

“Mommy, don’t go, wuwuwu…”

Shen Qinghan clung to the gate, tears streaming endlessly as she sobbed like a weeping doll.

Xu Meng gently comforted her, “Hanhan, don’t cry. Mommy will come pick you up after school this afternoon.”

Shen Qinghan kept crying.

Helpless, Xu Meng turned to Lin Zichen, “Chenchen, help Auntie Meng take care of Hanhan. Auntie will pick you both up after school.”

“Alright, Auntie Meng.” Lin Zichen nodded.

Before long, the kindergarten gate closed.

With no parents left to watch, many children stopped crying.

After all, with no audience, the actors lost their motivation to perform.

In their place, the kindergarten teachers got busy.

To help the children enjoy kindergarten, the teachers gently organized games.

In Lin Zichen’s class, they played arm wrestling to see who was stronger.

The rules were simple, easy for the kids to understand.

Most importantly, it was face-to-face, helping the children quickly get to know one another.

Lin Zichen wasn’t interested, thinking of finding a corner to exercise.

But seeing that Shen Qinghan wanted to play, he went along with her.

After a while, Shen Qinghan was fully immersed, laughing and talking with a little girl wearing a bun hairstyle, so Lin Zichen quietly slipped away to do push-ups.

Not long after, Shen Qinghan suddenly needed to pee and went to the bathroom hand in hand with the bun-haired girl.

They went in laughing, but came out with their friendship broken.

“You’re so big and still wear diapers, shameful. I won’t play with someone in diapers!”

“I—I don’t, I didn’t…”

Faced with the bun-haired girl’s disgust, Shen Qinghan was at a loss.

“Everyone, don’t play with her. She’s so old but still wears diapers, it’s embarrassing!”

Whenever other girls passed by, the bun-haired girl told them not to play with Shen Qinghan.

Shen Qinghan was on the verge of tears.

She had wanted to make many friends at school, but how did it turn out like this?

Blaming the diapers, she quickly ran back into the bathroom to take them off.

But even so, the bun-haired girl still shunned her.

She even gave her the nickname Diaper Princess and urged everyone to isolate her.

Children’s malice always came sudden and without reason.

Shen Qinghan felt the sting of it and lost all hope for kindergarten life.

Wiping her tears, she ran off to find Lin Zichen.

Now she finally knew—only Lin Zichen would never despise her for wetting herself and would always be her friend.

[Your Biological Level has risen to Ordinary Second Tier]

Lin Zichen was focused on training when a sudden notification appeared.

His Biological Level had broken through!

In disbelief, he quickly stopped and opened his status panel.

[Name: Lin Zichen]

[Age: 4 years]

[Biological Level: Ordinary (Second Tier)]

[Biological Attribute: Use It or Lose It]

It was true—he had advanced from Ordinary First Tier to Ordinary Second Tier.

Just days earlier, he had tested his stats:

He could lift an 80 kg sack of rice with one hand.

He could jump 1.2 meters in place.

He could sprint 100 meters in under 11 seconds…

Though still far from world records of his past life, these were top-tier results for ordinary people.

Without specialized training, such feats were impossible.

‘So… Ordinary Second Tier means being among the very best of ordinary adults?’

For the first time, Lin Zichen grasped the meaning of Biological Levels.

By that logic, Ordinary Third Tier strength should be enough to smash past all world records.

Far surpassing them, even.

Just then, Shen Qinghan’s voice came.

“Chenchen! Chenchen, I miss mommy! I want to go home…”

She ran up to him, eyes filled with tears.

Lin Zichen was puzzled.

Hadn’t she just made a new friend?

Why was she suddenly crying to go home?

“What happened?”

He wiped her tears, speaking gently.

Between sobs, Shen Qinghan recounted everything.

Lin Zichen stroked her head, “It’s okay, we’ll always be best friends.”

“Mm, best friends forever, pinky promise… hang by a string… for a hundred years, no change!”

Shen Qinghan hooked her little finger with his, smiling through her tears.

At naptime.

Once Teacher Strawberry left, Shen Qinghan immediately climbed into Lin Zichen’s bed like a little kitten.

Because she had been excluded that morning, she now clung to Lin Zichen even more, relying on him completely.

Lin Zichen found it hot and uncomfortable sharing such a small bed but let her be.

Soon he drifted off to sleep too.

Halfway through, he suddenly felt warmth on his body.

He shot up, lifted the blanket and found that Shen Qinghan had wet the bed.

The mattress was soaked.

Lin Zichen was stunned.

Wasn’t she wearing a diaper?

Where was it?

Why hadn’t it worked?

As he wondered, a nearby boy who hadn’t fallen asleep spotted the wet mattress and shouted:

“Bedwetting! Look, Chenchen wet the bed! And Hanhan too, they both wet the bed, so embarrassing!”

The surrounding kids turned to look, joining in the mockery.

“You’re so old and still wet the bed, you’re both naughty kids!”

“We won’t play with you anymore!”

“Bedwetting at this age, from now on you’re the Bedwetting Royals!”

Shen Qinghan woke up to the taunts and broke down crying, “Mommy, I don’t want to go to kindergarten anymore, I want to go home, wuwuwu…”

If it had only been him being mocked, Lin Zichen wouldn’t have cared.

But hearing Shen Qinghan’s sobs, he knew he had to act.

He jumped up, landing with a thud on the table, glaring down at the noisy children with overwhelming authority.

“Shut up, all of you!”
