Mercenary System: I can increase innate potential !

All of a sudden, various watches appeared from nowhere in different places around the world. These places were very quickly controlled by various organizations, and then the marketing of the watches was strictly controlled. Why was this? Because these watches allowed access to a unique world: Eternity! In this world, it was possible to increase one's physical strength, to unlock new classes and to acquire various skills and talents! It also allowed you to awaken your unique talent! And above all, there was a meager possibility to increase his life expectancy! It was with the aim of changing his destiny that Maxime trained all his life in the handling of the sword, and that he saved his meager salary for many years to obtain one of these famous watches! Watch his rise in the real world through Eternity! IMPORTANT: The name of the book will soon change to "Mercenary System: I can increase innate potential". Alternative title "This is my mercenary group!" If you like the story, don't hesitate to make a small donation of 2/3euros on my paypal.
