1. Take the 3 1 rating of Crouching Rabbit, Hidden Dragon as an example. After the player successfully passed level 30, we still need the apartment event to unlock level 3 1. If it is completed as shown in the figure below, you can directly click the Unlock Story to successfully unlock the 3 1 level.

2. If we haven't finished the corresponding apartment story before, we need to go to the apartment, click on the activity at the bottom right, and complete the purchase with gold coins on the newly opened page to unlock the apartment story. If there are not enough gold coins, you can get them by playing the level where you didn't get the golden radish before.
