I Can Level Up By Sleeping, I Become The Supreme Lazy Bird

Two eggs in one nest, I am the reincarnation of a loser, and my sister is the reincarnation of an empress.

The empress started with the blood of a divine beast and worked hard to cultivate just to return to the peak and take revenge.

My sister is a divine beast, a blue phoenix, and my parents are sixth-level demon kings.

I am a low-level blue-feathered bird.

My parents are silent, my sister is silent, and I am sleepy.

The empress's sister worked hard to cultivate and finally achieved success.

However, just when she thought she was the strongest genius in the world, she discovered that her brother, who had been eating and waiting to die, had become the strongest supreme...

It was not until this time that she realized that the lazy bird was the most invincible!
