Weird Cave: You Call This a Slave?

When I woke up, I was in a strange cave. Monsters are weird, dangerous, and even become lowly slaves themselves. In order to survive, if they disagree, it will be life and death. Just when Zhang Fan thought he was going to die, a system notification sounded in his mind. This is a detection system that can tell you everything! "Ding! There is a fairy sword left over from the fairy world three meters in front of the host!" "Ding! A dying immortal is found ten meters in front of the host. Kill him to get his treasure!" "Ding! A child of destiny is found in front of the host. He has broken through the third level of Qi training. Please kill him in advance! To avoid killing the host in the future!" … As Zhang Fan gained more and more things, his strength also grew infinitely. At this point, Taichu Continent lost one slave who was confused about survival. There is one more powerful power that makes all continents tremble... Zhang Fan! !
