Bro, I'm not an Undead! - Chapter 1448: The Same Thing You Did

Li Wei accidentally obtained a simulator that allowed him to manage a family of cultivators. He discovered that the descendants in the game would offer him strange and unique sacrifices.“Thanks to the ancestor for the gift, our family has become the most powerful family!”“Hurry up and offer a sacrifice to the ancestor. Please accept this spiritual weapon!”“Ancestor, we have already conquered the immortal world!”Then, one day, the descendants of the Li family, who had been in the game, appeared on Earth in grand flying boats. Under the astonished eyes of the entire world, these descendants paid homage to Li Wei in great numbers.“Welcome our ancestor home!”

Coming from the modern era, she was sent to a strange world. The body she possessed previously belonged to a young woman whose family was thrown away by their clan. However with the “Dan Fu Zong”, the inheritance from her old world, she steps on the path of cultivation, hoping to one day become an immortal.

Yuki, a high school junior, dies heroically saving a stranger and is reincarnated in a fantasy world, where he discovers an extraordinary and unrivaled power.

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.

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.
