In the first year of the apocalyptic cataclysm, virologist Rong Yu died heroically by sacrificing himself to detonate a closed area in order to kill the ultimate mutant and protect humans and their children. Unexpectedly, she was unexpectedly reborn as a soul, descended into a new era seventy years later, and possessed the body of a despised 18-year-old girl from the ruins. Now the son she had fought so hard to protect was now the head of the Ji family who was seriously ill and in charge of the lifeblood of mankind, and her two outstanding great-grandsons were also at the core of the safe zone. Carrying the knowledge and bloodline obsession of his previous life, Rong Yu sheds his identity as an ordinary good-for-nothing and counterattacks with a strong force. With a brand-new young body, he once again protects the bloodline and the hope of mankind that has spanned a century.
