Tomorrow's Ark, raised by children

I am the son of a chef. My dad knows Shangshu cuisine best. It is said that the imperial chef retired and returned to his hometown. He was once a famous master in the capital, but I am not sure if he is lying.
There is also a strange thing recently, a woman comes to the door every day to eat and drink.I wanted to beat her, but my dad wouldn't let me, saying I couldn't beat her.
She said her name is Nian, and I want to fight her hard, she said wait until I grow up.
Then the blind middle school boy died, and my dad died too.The year is gone.
I didn't hate her anymore by then.
Later, when I walked away from Terra with my sword, I felt that I was already the ruthless person of the Hammer Behemoth. After returning to Yan Kingdom, I saw her again...
"You are.....?"
"Zhang Yubai!"
She smiled awkwardly.
"They are all acquaintances, please accommodate..."
"Stop talking!"
I am not avenging myself!
"Then... Gloria, Mostima, my sister, that Kelsey, and... what's going on with them?"
"Ordinary friends!
There is gold under the man's knees, it is a last resort!
I knelt down.
ps: Miss Nian is number one in the world!
