There are three difficulties in the secret realm of "Collapse Star Railroad": The Sign of World Breaking. Players need to find Wuwubo to pass the level. Please take a look at the guide for clearing the level of "Collapse Star Railroad": Sign of World Breaking in all difficulties brought by the player "Sacred Fish" below. Hope it helps everyone.
If the development level is ≥ 22 and you have completed Esda's companion mission, you can open the secret realm of signs of the world.
Omen of the World Split is divided into 3 levels of difficulty. You will get 30 Stars for clearing 1 copy, and 10 Stars for completing 1 star. A total of (30+10×3)×3=180 Stars. How to play: First find the Woowoobo, then get close to it (it cannot be recognized if it is too far away, but it does not need to be too close), and finally use the camera to identify it (difficulty I has 4 Woowoobots, difficulty II+III has 5 Woowoobots).
