So Ye Xuan decided to collect the wool of the system, and he would not go out until he was invincible until the end of time. Countless years later, all the disciples he casually accepted became Immortal Emperors, and all the demon beasts he casually inspired became Demon Emperors.

Ye Xuan, who was already invincible, finally decided not to be stubborn. As he took one step forward, dozens of Immortal Emperors rose into the sky, millions of monsters roared towards him, and hundreds of innate artifacts caused the world to change color...
