You will play one of the six characters with different positions, missions and fighting methods, , and sneak into the armless and unpredictable Xianyang, the capital of the Qin Dynasty, to explore, collect, fight and grow in this historical wuxia punk world.

You need to reasonably plan the buildings and order of exploration within the time limit of 72 hours. The environment and content of each building may change according to the time and the triggering of some world events.

Face-to-face duel? Stealth assassination? Borrowing a knife to kill? Winning without fighting? Facing the enemy creature cards that have just entered the room and are covering the field, you can freely choose how to deal with them according to your deck construction and the room environment.

In addition to combat actions, your deck also contains various "object cards" and "exploration cards" that can be used outside of combat. They will help you crack mechanisms, change the environment, search for treasures, and communicate with the characters in Xianyang City.

All your action cards in battle come from the swords, armor and mechanical prostheses you equip. There are hundreds of these weapons and prostheses in the game, and the same weapon may carry different action cards when it is dropped repeatedly. You don't need to be limited by your early construction choices and be forced to go to a specific genre. Instead, you can change your equipment at any time to change your genre after obtaining new weapons and prostheses.
