I'm an Undercover Agent on Earth

Among the ruins, scorching fireballs streaked across the sky, and icy sword energy swept across all directions. On the battlefield in the distance, war horses neighed, dense bows and arrows blocked the sky, and the cavalry rampaged through the formation, leaving blood and flesh flying everywhere.

The young man took out a long-cherished Tuanlong Medal from his arms, with a smile on his face: "I'm sorry, I'm an undercover agent." Latent mission, completed.
