Disaster? Please Tell Me to Destroy

Single heroine + group portraits + fantasy (with some personal settings added) + original world view (the incomplete world view in the early stage may look a bit weird, but you have to believe there will be an explanation later.) He is the first creature born in this world, and his body is filled with the origin of destruction and destruction. A "cursed" baby was born. He suffered pain that others could not understand. He became taciturn. Even though his parents continued to comfort him, he became extremely inferior in his heart. A girl who was born like a little sun. When facing her enemy, she was the only one left in the whole family. Her burning heart had cooled down. Under the care of her adoptive father, she regained some vitality. Her power was also waiting to be awakened. The world has entered a new reincarnation and has begun to mature. He is coming. What will be their fate? In the process, the past is gradually revealed, and the world may move towards a new chapter.
