当我进入到森林这张地图时，突然进入到一张空白的地图，里面什么都没有，只有箭头引导我去找五只史莱姆。当我找到五只宇宙史莱姆之后就通关了，这是一个bug还是一个彩蛋？
When I entered the forest map, I suddenly found myself in a blank area， There's nothing inside, just an arrow guiding me to search 5 slime. After finding five universe slime, the game is cleared. Is this a bug or an Easter egg
