I'm Already a Purple-Robed Celestial Master, Who Still Uses Paper Talismans?

Li Er transmigrates to a parallel world. This world has entered the Age of Declining Dharma, and spiritual energy is terrifyingly scarce. As the sole heir to a Taoist temple, Li Er has a sudden inspiration and gives its magical artifacts a little modern upgrade. "It's the modern age. You're still using talismans?" "Your Five Thunder Technique doesn't work? Use this!" "What? A wicked dragon is wreaking havoc in the East Sea? Then I have no choice but to press this button." And so... A brand-new AK-47 takes the place of traditional talismans. A stun baton loaded with liquid lightning replaces the Five Thunder Technique. A button for world nuclear peace replaces the formation used to suppress the wicked dragon. Taoist priests across Huaguo watch the weapons in Li Er's livestream and flood the chat with messages: "Fellow Daoist, can you add links to the stuff in your livestream?"
