Review Detail of Hussein_Nasser in Power Leveling System

The idea is good, but the implementation is not good. The story is going so fast, world building is unclear. The background of the main character is incomprehensible. Is this the same as his previous world or a new world, and how did he move to this world? The story needs to clarify and solve these problems. I think the novel has potential for growth, so I keep going. I apologize if the writing is incomprehensible. English is not my native language.
