Journey to the West: I Taught the Eighty-One Tribulations, and They All Became Sages

Li Yushu transmigrates to the Primordial World and happens upon a celestial herb. After keeping a low profile for hundreds of years, he becomes a Heavenly Immortal. To ease his loneliness, Li Yushu teaches enlightened demons the Great Dao of calculus and trigonometric functions, earning himself the title of Demon Master! Then the Journey to the West Tribulation begins, and the Dao-preaching, ten-thousandfold-reward System activates. “Ding! Your disciple, the Black Bear Monster, has comprehended the Anlan Art and obtained the Anlan Imperial Clan's ancestral bloodline art!” “Congratulations, Host! You have received a ten-thousandfold return and gained a hundred thousand years of cultivation!” “Ding! Your disciple, the Nine-Headed Insect, has comprehended the Nine Nether Ao's art, one of the Ten Primordial Ferocious Beasts!” “Congratulations, Host! You have received a ten-thousandfold return and obtained the supreme arts of the Ten Ferocious Beasts across the myriad heavens!” “Ding! Your disciple, the Green-Haired Lion King, has comprehended the Heaven-Devouring Demon Art!” “Congratulations, Host! You have received a ten-thousandfold return and obtained the Heaven-Devouring Emperor's Art!” “Ding! Your disciple, the Golden-Winged Great Roc…” Before anyone knew it, all those involved in the Eighty-One Tribulations had become saints.
