MTL - Heroes of the Invincible Undead - Chapter 40 Watchtower II

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.

Now, I’m trying to save the world using the ‘System’ I gained as the ‘Regressor’s Privilege’… but the Main Heroines have also awakened their memories of the previous timeline.

God damnit.

And so, a deadly game of sheep and wolves unfolded...

Traveling through the fantasy world, after hundreds of years of tossing, Han Li, who is of mediocre aptitude, is ruined.

After going down the mountain to marry a wife, he found that the way he opened the fantasy world was wrong.

You can rise from lying down, why should you practice hard, fight and kill?

Many years later, a long-lived family quietly rose up, with tentacles all over the heavens and worlds, and behind the scenes they controlled the various holy lands and immortal mansions.

On this day, Han Li was high in the ninth heaven, looking at the billions of descendants below, telling his glorious history.

A fairy emperor came across the border, intending to destroy the Han family, but was killed by Han Li with a snap of his fingers.

Immediately, the heavens were shocked, that ancestor Han was so strong!

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.
