“Nine Heavens cast down the Undying Tree, from the tomb the Immortal's bones were fetched;Taoist Venerable tut-tutted as they drank blood plasma, Old Buddha relished in the chew of meat;Beasts and livestock rang the Dharma Drum, city foxes and hole-dwelling rats boiled in the pot;In the Immortality Wine, the resentful spirits were fishy, at the Killing Banquet, the Dao Fruit was bitter!”In this world where Daoist Skill manifested, countless Sect Cultivators, Side Door Magicians, princes and scholars, officials of high rank and nobles all coveted immortality!Owl God Tomb, stealing heavenly secrets, Pearl Gathering Skill, Holy Infant Pill, bone effigies, Yin God Shrine, human-transformed monsters, Undying Elixir, Red Line Poison, Blood Immortal insects, Mermaid Meat, gold-threaded robes, Five Poisons Primordial Spirit, Seven Star Life Extension...They killed and harmed life only to steal the “Killing Dao Fruit” borne upon that Undying Tree!Until... a sly “Fishing Man” came to this world.Wang Yuan, born with the Small Book of Life and Death, had but a simple and unadorned dream:Amid bustling strings and smoky vistas, on a night bathed in moonlight, in peace and quiet did I lean on the rail, savoring the wind, toasting to the stars.With his “Bride in bridal clothes,” watching the sunrise at Taishan in the morning, admiring Qionghua in Luoyang at noon, and drinking under the aurora by the North Sea in the evening.“But you all smell so incredibly fragrant!No more, none shall escape, for today I shall crowdfund Cultivating Immortality! Please... my treasure, turn around!”The blood-red veil of the Bride abruptly fluttered to the ground.

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.
