An undercover shaman was found tortured to death, leaving a huge shadow. After his death, he inexplicably came to a world between Sancha. Less than 1% of the indigenous people, most of them died, had to pass a test every week. The first step was to find the "key" to the dungeon. The "key" is not necessarily a key. Here he met Zhuang Ji. As an aboriginal, he had several companions who called him dungeon pass. Otherwise, he would not have survived until now. Until they reached the dungeon at the end of the world and discovered an unknown secret.
