He transmigrates to another world called Eternal Divine Realm, to the Eastern Continent, in a country called Great Xia. He is reborn into a general's household, where his parents love him. From the moment he is born, he notices that his strength increases a little every day, though the change is slight. This continues for the first ten years, but then stops for the next five. After trying things like slaughtering chickens, he discovers that only killing living beings can increase his strength.
