MTL - Cthulhu Gonfalon - Chapter 863

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.

In a world of shallow-minded, materialistic mortals, what would one from humble beginnings – whose face had been stomped on, spat on, oppressed for the longest while by the arrogant, pampered upper echelons of society – do, when a mysterious application pops up on a brand new phone that was meant to be the birthday gift of an ungrateful girlfriend? What if the application takes the form of a chatroom where its occupants, bearing the names of mythical, fictional beings, start giving out ‘Red Packets’, all the while spouting nonsense?

Before Li Daniu had time to be excited about being a prince who was about to ascend the throne, he learned that his country was about to be submerged by sea water.

“Can I wear it back?”
