The space-time rift that opens every sixty years in Chang'an City involves Cuju masters from all dynasties in a strange tournament. Li Yun, the night watchman of the imperial mausoleum who pretends to be lame, is exposed by Su Wanyue, a cultural relic restorer from the 22nd century - she traveled through time just to record this game that may rewrite history. When pirates, cat monsters, and future robotic arms became teammates, and when the ball under his feet began to speak, Li Yun discovered that the so-called game was actually a time and space vortex transformed by Li Shimin's dying obsession. The powerful eunuch Zhao Wuji is using the system to manipulate the results in an attempt to reap the "imperial regret" and tamper with the national destiny. Now, Li Yun must kick a pass that spans a thousand years in the decisive game - not to his teammates, but to the three teenagers who can never stand side by side that night at Xuanwumen.
