In Another World, I Only Know the Most Basic Fireball Spell

A very nice book! The subject matter is very new! The male protagonist hides his strength. He appears to be useless, but is actually very powerful in fireball. Although he was born in a wealthy and warm family, he likes to walk alone in the darkness and use his own power to save others, punish evil and promote good, and his strength is constantly improving. His sister is so arrogant, haha, but she can also tell that she loves her brother very much. I really like this kind of novel, it is not overly emotional, but the story is rich and humorous... Will keep reading ~ I look forward to the author's continued updates ~
