Si Xia is a wage slave who lives in a 600-square-meter siheyuan inside Beijing's Second Ring Road. But really, he's just a live-in cat-sitter. The landlord is a cat. Utilities are free, and as long as he pays for cat food, he can stay as long as he likes.
By chance, he activates a [Door] that lets him travel between two worlds. The destination on the other side is as exciting as opening a blind box.
Struck by lightning in a primeval forest, fishing in a snow-covered mountain in the dead of winter, stumbling into the middle of a pack of dogs fighting, hanging from a tree while listening to a wolf choir, racing wild boars for dear life, and risking it all to pet a wild giant panda.
When he finally meets people, they're bandits robbing travelers. A young lady who drops out of the sky turns out to be a man in disguise. He visits a brothel and finds himself at a murder scene, gets accused of hitting someone after stopping to help, ends up at a shady inn when he goes out to eat, hears the best part of a story at a teahouse interrupted by a spoiled rich kid, and tries to climb over a garden wall to leave, only to meet the owner climbing back over it.
...None of that is a big deal.
Haha!
Suddenly appearing in the Golden Throne Hall during a grand court assembly, with hundreds of eyes fixed on him?
Help!
How can he play it cool without being found out by the nation's top minds, all of them purple-robed bigwigs with eight hundred tricks up their sleeves?

▼ Money is no problem
▼ The cat emperor is underage, so no romantic advances allowed
