Does anyone know of a webnovel where the mc has a system that I think allows him to get stronger by being killed and gains abilities of that person/thing and the first chapter his is in a cave and dies and gains a body that can survive forever without food and water? And a women falls down while being chased and I think the people are trying to kill her and joins him also the system will accept if the mc wants to commit suicide and allow him to finally die? Or anything like this?
