I Conquer Other Worlds with a Spittoon

A young man who traveled through time became a consumptive young man, and his magic weapon was actually a spittoon? Just spitting can make the enemy so unlucky that they drink cold water to stuff their teeth. My family regards me as a shame, but they don't know that I have the mission of completing the way of heaven and awakening the ancient emperor. When I pointed the spittoon at the so-called genius and goddess, the whole world began to tremble: "Please stop vomiting!"
