In a distant village, Yale, the master of three emperors - Green, Yellow, and Chance - fell into a deep sleep, always accompanied by his loyal pet dog, Dark. Unexpectedly, a group of immortals seized this opportunity to attack Yale. Despite Dark's valiant efforts to protect him, Yale suffered a serious blow to his sacred soul. Consequently, Yale was transformed into a baby, and Dark reverted to a regular dog. Fortuitously, Quinlan Chapman happened upon them and took both Yale and Dark into his home. Years later, Yale grew up as the heir to the Chapman family. While confronting a bully named Charles Chapman, Yale's memories and strength were restored. Thus, the Mighty Lord returned!
