Sword Sect Little Demon Child, Three and a Half Years Old and Extremely Fierce

This is a sad story about poverty.
My father was so poor that he lost his underwear, so he sent me to the world of immortal cultivation to find my mother.
The sect looked down on me because I was a useless person with five spiritual roots.
Only the Heavenly Sword Sect was willing to take them in because they were even poorer and had no other choice.
The senior students thought they had picked up a cute girl.
The result was the creation of the biggest bug in the cultivation world.
The genius of Qingyun Sect was brought to tears by my sword.
The young master of the Demon Realm is my own brother.
High-level monsters run away when they see me.
Now the entire cultivation world says I'm a spy from the demon realm?
I'm only three and a half years old. My dad is uneducated. I'm a second-generation illiterate. What can I possibly do?
Yes, I'm three and a half years old now, and I'm waiting online for a mother to claim me.
