Great Tang: You Said You Were a Fortune-Teller, So How Did You Become the Imperial Preceptor?

After transmigrating to the Tang Dynasty, Li Xuanqing used his “Daoist magic,” a bag of Yiwu-made knickknacks, to become Chang'an's most famous charlatan: the renowned Immortal Master Xuanqing! Every day, he “exorcised demons and dispelled evil,” then dropped by Pingkang Ward to visit the young ladies at its many brothels. Life was wonderful. But fate had other plans. Princess Jinyang was critically ill, and the imperial physicians were helpless. As Chang'an's most famous “True Lord of the Dao,” Li Xuanqing was tied up like a dumpling and “invited” to the palace by the Imperial Bodyguard Corps! Looking at the little princess, whose breath was faint, Li Xuanqing panicked! I'm just a charlatan! I don't know magic, let alone how to heal the sick! What am I supposed to do now? Anyone there? This is urgent! At this critical moment, Li Xuanqing glanced at the inconspicuous prompt in the bottom-left corner of the engine interface: [Recharge one thousand taels of gold to upgrade the engine database. Would you like to recharge?] Well... should I take a chance? Years later, Li Shimin gazed at the Tang Dynasty's Imperial Preceptor, who could summon wind and rain with a wave of his hand and had not aged a day in decades. His expression was one of utter disbelief. “Imperial Preceptor! Are you saying there truly is no magic or immortality in this world?” “Of course not, Your Majesty. You must believe in science! There is no such thing as Daoist magic or supernatural powers, and immortality is utter nonsense!” Li Xuanqing declared with righteous conviction, then rode the clouds into the sky.
