Shen Jianxin and Shen Lanxin

Before they became famous, this was how Shen Jianxin introduced the Shen siblings:

"I'm Shen Jianxin, a security guard in Daoxiang Village. My dream is to become a renowned hero."

Then...

"Uh... This is my little sister, Shen Lanxin. You'd better watch out, she's super fierce... Ah!"

After becoming famous, this was how Shen Jianxin introduced the Shen siblings:

"This is my little sister, Shen Lanxin, a special columnist for the Great Tang Translation Gazette and a master of recommendation posts. Whatever you do, don't offend her. She's super fierce..."

"As for me, I'm none other than Shen Jianxin, the first name on the Heavenly Rankings, a hero with a heart of gold! Aah..."

Shen Lanxin: I'm so exhausted. Someone please give me a new brother!

Is this the story of a transmigrated woman who does nothing but roast everyone and pick fights with anyone she doesn't like??

Also known as "Shen Jianxin at the Bottom of Society," "Only I Get to Bully My Brother," and "Please Take My Little Sister Away"
