Progenitor Ku

## Introduction

Progenitor Ku (枯祖) was from the Fifth Mainland and part of the same generation as Progenitor Chen. He is the ancestor of the Ku family of the Court of Seven Names. He's given name was Ku Jie.

## Profile

He appears as someone who seemed to be in his early thirties, though most of his hair had already lost its color. He had a haggard look, and he was extremely skinny and had a rather ugly appearance. He had a gentle smile though, that caused those looking at him to subconsciously ignore his homely appearance.

Progenitor Ku was actually desiccated from birth, and he was discriminated against so badly that even his own parents did not want to touch him. His talent for cultivation was terrible as well, however, despite his poor talent, Progenitor Ku never gave up, and His transformation all began when he started training Waning Zen.

Progenitor Ku did not create Waning Zen himself, but rather acquired it from an ancient inheritance. It was not some powerful battle technique, but it did match Progenitor Ku's state of mind most perfectly. It was entirely because he trained Waning Zen that Progenitor Ku was eventually able to sit down and create Extremes Must Be Reversed. Without that, Progenitor Ku would have fossilized at that time. The Progenitor’s perseverance had far exceeded what most people could even imagine due to the scrutiny of his image and looks.

Extremes Must Be Reversed was an unprecedented technique that allowed Progenitor Ku to obtain a normal appearance for the first time in his life. From that point forward, Progenitor Ku maintained a low profile and essentially disappeared. It was never that Progenitor Ku was unable to compare to his peers, but rather that he did not wish to do so. Given Progenitor Ku’s personality, he was more than happy to maintain a low profile.

### Extremes Must be Reversed

Progenitor Ku developed the battle technique of Extremes Must Be Reversed which causes the user body to dry up and have a withered appearance. This battle technique stores the potential energy of attacks on the user as long as the attack does not exceed the user's tolerance level with the body recovers back to normal the more the user absorbs the potential energy. The user can then unleash all the stored compound strength back as an attack.

Progenitor Ku had achieved an even higher level with the battle technique: the Progenitor had learned how to use Extremes Must Be Reversed on other targets, provided that the target had reached a state of some sort of extreme. A so-called “state of extreme” referred to many different things such as time. Time was always in a state of extremes, because time was constantly flowing forward. It never stopped, nor did it flow in reverse. It always moved forward, always continuing in the same manner. This was a state of extremes, and Progenitor Ku had suggested that Extremes Must Be Reversed could be used with time, which was why he had left behind the Withered Bark. The Withered Bark that Progenitor Ku had personally created had been imbued with Extremes Must Be Reversed in a manner where, when used, the power vessel would reverse extremes, which meant that it would reverse the time around the Withered Bark. Progenitor Ku had not comprehended the power of time, but had instead used the Withered Bark as a tool to forcibly revert time. Extremes Must Be Reversed was not a cultivation method at all, but rather a way of understanding the state of the universe itself, which provided a means of transforming something rotten into something magical.

## Story

Progenitor Ku was one of the inheritors of the Nine Mountains and Eight Seas, alongside his peers such as Progenitor Chen, Progenitor Hui, and other Progenitors.

During that same era, Progenitor Chen was seen as invincible, and his fame spread throughout the universe. The Daosource Sect was still the ruler of all of humanity while the Rune Progenitor, Progenitor Wushang, as well as the Progenitors from the Lu, Wang, Bai families and more had not yet become Progenitors, though they were all already on their way towards becoming well known. Only Progenitor Ku remained unknown.

Progenitor Chen remained invincible and the Rune Progenitor mysterious. One after another, Progenitor Ku’s peers became Progenitors, and they even gained control of the Nine Mountains and Eight Seas. All of the major families were eager to see who would be the next to become a Progenitor, but no one even considered that Progenitor Ku, who was completely unknown, would be a contender. However, Progenitor Ku managed to surpass all other creatures and become a Progenitor, and he was able to do so entirely because of Extremes Must Be Reversed.

During the war between the Fifth and Sixth Mainlands, Progenitor Ku did not participate, but it was because he went out alone to slaughter the Aeternals. Progenitor Ku went to confront the Aeternals alone, and he never returned. Of everyone alive back then, only the Aeternals know just how powerful Progenitor Ku was back then because he never revealed his power before humanity. Still, he was far from weak, as he fought against all Seven Skygods, as they were the only powerhouses from Aeternus that had the strength to stand up to Progenitor Ku.

Progenitor Ku has his residence of the Voidsoul Palace in the Dominion Realm of the Perennial World close to the center where only those that are strong could live. The Voidsoul Palace at the Dominion Realm had been a trap set by Forgotten Ruins God for the Junior Progenitors which Lu Yin had managed to escape. Lu Yin gained the battle technique of Extremes Must be Reversed from the Voidsoul Palace.

The Extremes Must be Reversed allowed Lu Yin to survive the tribulation Progenitor Chen at the Enlighter realm, and his innate gift of Heaven's Furnace, survive against poison of Samaritan Tears.

Progenitor Ku was seen during the time skip sequence during the Daosource Sect ruins of the Fifth Mainland, where he was with Zhao Ran. Progenitor Ku was able to completely bypass Xu Wing, Undying God who was one of the Seven Skygods saying that he was not Progenitor Ku's opponent. Progenitor Ku invaded the Aeternal's realm and forced his way through by himself.
