Overpowered Wizard - Chapter 121: B2: C21: Master Ranker

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

He would once again be cursed to the danger of crossing over into a book.
During the time when he broke free of his shell, what he first saw was just the handsome, handsome male lead that he had written.
During the time when the male lead was pinching the small soft flesh of his neck, it was also his first time hearing the male lead’s voice.
“Return goods,” the male lead said in this way toward the vendor stall’s owner.
Pei Bufan: “…… meow?”
