In the martial world, disputes often lead to immediate violence, frequently harming innocent, unarmed civilians who either lose their wealth or their lives.Lu Jianwei merely complained a few times when she was suddenly bound by a system and transported to ancient times, tasked with running an inn according to the system’s rules.The foremost rule of the inn is—No fighting within the inn.Violators will either lose their wealth or their lives.A mysterious inn suddenly appeared in the martial world, rumored to be a shady establishment dealing in mu*der and robbery.No matter who enters the inn, they either leave penniless or lose their lives.The bold and skilled “Know-It-All” of the martial world, eager for firsthand information, sneaked into the inn alone to trace the whereabouts of missing people, only to be horrified to discover—Isn’t that diligent woodcutter the number one swordsman of the martial world?!Isn’t that agile waiter the number one thief of the martial world?!Isn’t that chef wielding a kitchen knife the number one beauty of the martial world?!Isn’t that farmer hoeing the ground the top disciple of the Martial Alliance?!And that…Before he could flee, the inn’s beautiful and gentle landlady stood before him with a smile.“The inn still needs an accountant. You’re it.”Know-It-All: I’m just a seller of information, I can’t do accounting ahhhh!Reading Guide:① Not a serious martial arts story, focuses on management + face-slapping + drama;② The female lead is the strongest throughout the story (pretending at first, truly strong later), the male lead appears later;③ For fans of overpowered management stories, all settings in the story are fictional.

On this land of real souls, with millions of different martial art institutions, there are so many strong fighters just like the trees in the forests.

Among all, a mediocre apprentice from one of the mediocre institutions suddenly became a martial art genius after a mysterious incident. Not only did he acquire a photographic memory and keen perception, but he had also come to discover that his ability to comprehend martial arts is astronomically good, which eventually made him an almost godly existence.

From the hot-blooded intense battles to the clashes between the top geniuses, Martial Arts is no longer limited to the mortal world, it reaches to a level that can do everything from controlling the oceans to flying up the sky and diving under the ground.
