My shadow is 100 million points strong

Introduction: Various extra-dimensional creatures invade, energy comes, and human beings begin to awaken various abilities, including weapons, plants, animals, and natural systems... The protagonist awakens shadow powers at the beginning, and I thought he was very weak! I didn’t expect Yiwai to be a bit strong! From then on, others risk their lives, but the protagonist enjoys a boring life of being carried away by shadows and winning even while lying down!
