Review Detail of Kura in Gravity Mage with Level-Up System

Very slow, MC is an idiot. Obtains system and do nothing with it and accept it as normal thing happening. Writing is juvenile and repetitive words in each chapter allowing for word count (Mc point of view) is written everywhere 23 chaoters in needing to pay???? Disappointed respect to author for trying but unfortunately I can’ t get past chaoter 23.
