The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.

On the dawn of a fresh New Year, an ominous figure emerged, shrouded in a guise of an angel but harboring the malevolence of a devil. With a chilling voice, it proclaimed, [Every month, you humans will be thrust into a perilous quest. Your survival hinges on overcoming 20 grueling rounds.]Suddenly, I found myself ensnared in this dangerous survival game, a grotesque merry-go-round where every turn carried the stench of death. Yet, I was not without any defenses. I possessed an unusual power: the power to regress 100 times, a chance to rewrite my fate.I stand on the precipice of my final regression, and I swear, ‘This time, I will conquer it. I will emerge victorious.’I’m no longer the insignificant shuttle that I once was. Today, I shed my former self, the one who had reached the pinnacle of power. Today, I am reborn for the last time as Black Scythe, a rookie player, a novice that once again will be become the Grim Reaper!

The youngest, silly fourteenth son of the Yan Emperor had reached the age where he should be given a separated territory now. He rejected the wealthy land, neighbouring the capital city, and instead chose the wildest land in the western region— Liangcheng. Everyone shook their heads and sighed. A fool is indeed a fool. If you go to Liangcheng, you will be killed by barbarians in less than three to five years.

One year later, the watermelon presented to the Emperor as the tribute from Liangcheng in the west was sweet and crispy. There was no one in the palace who did not love it.

Two years later, Liangcheng presented corn as a tribute to the Emperor. The yield was high, and the taste was good. No one in the country could resist liking it.

Three years later, Liangcheng defeated the barbarians and presented their prisoners in front of the imperial court. The people of Yan were excited and their morale was greatly boosted.

Four years later… Everyone said that the fourteenth prince Mingyu was a fool, while the little fatty Yu, who transmigrated with the golden finger, chuckled. Let’s see how you guys look at this fool build his own territory, then.
