Rebirth and Life Change: He Loves His Arch-Rival Like Crazy

There Is a Dark Horse in the Post-Apocalyptic Survival Category. It Is Hard-Core and Thoughtful. I Highly Recommend It.

I want to read a book similar to "Black Rain 2027". This book has no cheats, is pure hardcore, full of human trials and worldly experiences, as if it really happened, and everyone is lifelike. The protagonist is low-key, has a human nature, high IQ and understands human feelings, and is supported by the delicate writing style.
