Journey to the West: I Am a Demon Master, and I Will Teach the an Lan Method at the Beginning

Li Yushu, who traveled through the prehistoric times, accidentally ate an elixir and became an immortal after living in obscurity for hundreds of years. In order to relieve his loneliness and boredom, Li Yushu talked about calculus and trigonometric functions to those monsters who were enlightened by spiritual wisdom, and he was honored as a monster master! Until the Journey to the West Calamity Tribulation begins, the preaching ten thousand times return system is launched. "Ding! Disciple Black Bear Monster suddenly understood Anlan's method and obtained the Anlan Imperial Clan's bloodline ancestral technique!" "Congratulations to the host for getting a ten thousand times return and gaining a hundred thousand years of cultivation!" "Ding! Disciple Nine-Headed Insect understands the Nine Nether Dragon Treasure Technique, one of the ten evils in ancient times!" "Congratulations to the host for getting a ten thousand times return. The host has obtained the ten evil treasures of all ages!" "Ding! My disciple, the Green-haired Lion King, has realized the Heaven-Swallowing Demon Technique!" "Congratulations to the host for getting a ten thousand times return, and for the host to obtain the Heaven-Swallowing Emperor's Law!" "Ding! Disciple Golden Winged Dapeng..." I don't know when, all the ninety-nine and eighty-one difficulties became saints.
