There is a legendary divine art in this world called the Heaven-Burying Scripture. It can bury the heavens, the earth, and all living beings. Anyone who cultivates it can gain supreme divine powers and even become the supreme ruler of heaven and earth.
Ye Wu transmigrated here. His father, the Divine Might Marquis, died in battle in the Northern Mang, and their ancestral cultivation art, the Heaven-Burying Scripture, attracted the covetous attention of foreign enemies.
Fortunately, he obtained the Heaven-Defying Fate-Changing System, which let him draw source energy from all things and use it to upgrade martial arts and cultivation techniques.
“Bury the heavens, the earth, and all living beings. Heaven-Burying Scripture, upgrade!”
“All my enemies shall be buried!”
“Even the immortals and gods of the heavens can meet their twilight!”
