One day, a mysterious tower suddenly appeared in the city. The people decided to call it a dungeon, and while it was full of rugged terrain and dangerous monsters, it was also a land of opportunity, where countless treasures awaited. When Sejun, a young man living an ordinary life, is invited to the dungeon by chance, he is thrilled at the prospect of becoming rich, but he is stranded in a hidden area of the mysterious tower. All he has is a few seeds and his body. Now Sejun must farm, collect resources, and figure out his own survival strategy!

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.
