Zachary Ying knows nothing about China. The school only teaches Western history and mythology, and my Chinese mother doesn't like to talk about her past. It's time to take a crash course because Zach's mom has been kidnapped by demons who are trying to open a portal to the underworld, and the spirit of the First Emperor of China has inhabited his augmented reality glasses and is commenting on everything that is happening. Now Zack has only fourteen days before the Month of Ghosts to team up with one of the most notorious tyrants in history to reach the Celestial Empire, steal powerful artifacts, fight for the mortal world and save his mother.
