Maoyuu Maou Yuusha - Volume 2 Chapter 9, “The Great Demon Conference, the Kurultai”

Chen An traveled to the world of cultivating immortals, and his cultivation talent was extremely poor. He was stuck in the third level of Qi refining for many years and could not make further progress.

Seeing that there is no hope of cultivating immortality, he chooses to return to ordinary life, and marries a wife to enjoy the ordinary happiness.

As a result, on the night of their marriage, they returned to the fairyland overnight.

It turned out that marrying a wife and enjoying ordinary pleasures was his way to become a fairy, and it could directly save him thousands of years of detours.

- Description from novelbuddy

The tens of thousands of universes have merged. The disintegration of spiritual force led to the momentous collapse of the great Cultivation World, a mighty era that had endured through millions of years of history. In the wake of the large-scale invasion of the Wilderness, the Avalon of Five Elements has become the practitioners’ last stand.

Caleb suffered an accident while driving a car that claimed his life. Only to reincarnate in an entirely different world. He thought that it was his second chance to climb the peak of life.However, he died in his second life at the age of five years old tragically. Then he was reincarnated again!He died in his third life at the age of fourteen years old; he died due to various reasons ranging from natural disasters to machinations of people.It was a vicious cycle of dying and reincarnating. His initial confidence and vigor were replaced by horror and fear. He can't seem to get past 18 years old! He noticed a pattern that he was dying before he could even reach adulthood. He didn't know whether his infinite reincarnation was a blessing or a curse.“Who can tell me why can't I get past 18 years old!?”The feeling of dying, again and again, pushed him to the brink of insanity. So Caleb made an oath that he would strive to live past 18 years old and break the vicious cycle! For that, he knew that he needed to give his everything, and do things he didn't want to do, to survive!'Wait how the hell did I get reincarnated in the body of an orc? Not only humans, but I can also reincarnate as a monster!? What's next? A slime? a goblin?' Caleb stared dazedly at the sky, full of questions....Caleb has reincarnated time and time again billions of times. After acquiring enough knowledge, combining different power systems of countless worlds, and strengthening his soul, he found a way to godhood.This is the story of a normal human living a true, eternal life! An actual god!

As a successful villainous BOSS, in addition to having ideas and aspirations, one must also keep in mind three points:First, grow sneakily, don't act rashly (once a villain acts rashly, they basically won't survive past three chapters).Second, you're not a good person, so be ruthless (becoming more evil will make you three times stronger, while redemption weakens you by seven times).Third, remember the two points above. The moment you forget them, your end is probably on its way.
