My Bro Got Transmigrated

My name is Li Yao, and I am very panicked now.

I received a message from my deceased best friend. Even though she was a very good friend of mine and was pretty, I still had to panic.

Later, her best friend said that she had traveled through time and became a mage...

I know, I might.

Li Yao: "Where's the familiar you promised me, a delightful one? Why is it a pitch-black monster?! I want a refund! I'm telling you!"

Lin Xiaowei: "Get lost!"

Li Yao: "Okay!"
