Review Detail of Carefree_Dream in The Infinite Mystery

Interesting novel. The armor plot is also amazing. I like the way MC is introduced in this novel. Although he is thr reincarnation of a mighty figure, he don't have any memories of his past life. the Infinity symbol slowly let him experience his past life. The appearance of the mysterious lady was the thing that caught my attention the most. what exactly is the relationship between the mysterious lady and MC?
