After entering the big map, the operation method is WSAD, interacting with the level logo, and pressing the space bar to enter the level. The first level is super simple, and the recipe is very simple. Just slice the fish. The operation process is: slice the fish-put it on the plate-serve it. When the time is up, end the level. Because the recipe is simple and the tip required for customs clearance is very small, customs clearance is easy. You can unlock level 2 after entering the castle to trigger a dialogue. This level mainly unlocks a new skill-throwing. This level is not difficult, mainly to familiarize you with this new skill.
