I Play Games with Qin Shihuang

The protagonist travels to the Qin Dynasty and plays the game with the current First Emperor. The "Qin Dynasty" in the game is undergoing a strange "magic reform", and behind the remnants of the Six Kingdoms stands an extraterrestrial demon. The protagonist and the First Emperor must rebuild the Great Wall of Qin in the virtual world to resist high-dimensional invasion, and finally realize the invincible Qin army in the game into reality.
