Yun Long had travelled to the Burning Heaven Clan just after he had enslaved Fen Yujie, who was currently kneeling before Yun Long holding a pitch-black key that had a black mist masking it.

"Good… you may forget about me for now… and let the clan know that Fen Juechen is on an extensive cultivation journey and will only return in fifteen or so years… that should be long enough for him to achieve his revenge…" Yun Long said to Fen Yujie as he disappeared into the distance.

Yun Long flew into the sky, when noticed a haggard and bloodied Fen Juechen stubbornly drag himself away from the Burning Heaven Clan with a cold aura surrounding his young self.

Laughing a little, Yun Long wondered what caused him to have such a personality even at his young age… completely forgetting that he was physically the same age as him.

Fen Juechen heard the laughter, and thought that his older brother had come to humiliate him as he left the clan, but when he turned around to see the masked figure of Yun Long, he immediately put up a defensive stance.

"Hmm… good reactions… although if I wished to kill you, you would have never been alerted to my presence… come with me Fen Juechen… since your mother saved my woman's life, the least I can do is restore her sons true soul for her… although I wonder what path you will take with your father's madness…" Yun Long said to him in a cryptic manner as he grabbed him by his shirt, before they flew up into the air, travelling as far west in the Profound Sky Continent as he could, to the location of the Black Fiend Empire, a practical heaven for those that cultivate dark / devil energy, since it was surrounded by dark energy all year round.

Fen Juechen couldn't react in time, when he next opened his eyes, he found himself hovering a land of enormity, a dense sinister aura occupied the place, the ground looked like they had been occupied by the clouds themselves, with a light grey fog encompassing the land, but what feared him the most was the cries of the devil that resounded the land, cries of the wailing ghosts that caused him to shiver every time he heard one pass.

"Hmm… where is it… there we go…" Yun Long said after he spotted the highest point in the land, finally arriving where he wanted to bring Fen Juechen, who was struggling to even adapt to the cold air, let alone the dark energy seeping into his body.

"Who… who are you… what nonsense are you talking about?!" Fen Juechen asked as he prepared to go all out to escape from Yun Long.

Yun Long ignored him, he placed the black key into Fen Juechen's right hand, a sinister demonic presence emerged from his palms as soon as the key entered them.

"Ye Mufeng, come out from hiding… I already know you are here… just because you fear me, you do not even come out… honestly… no wonder you allowed your clan to die out like this…" Yun Long said in disdain after he felt the residual soul's awareness when he sent his soul sense to survey the area.

"Boy… This King has waited a millennium to find the one who would return this key to me… but only the one who has access to the key is the one that should be able to come here… who are you?" Ye Mufeng asked warily, his eerie voice rang out in both their minds, as he asked the question, he was simultaneously planning to get the boy to quickly unseal him so that he could get rid of both threats.

"Yes whatever… I brought Fen Juechen here as a gift for you… you will understand afterwards… Juechen, I will come back after you settle your things here…" Yun Long said as he flew off to a safe distance, sitting down, he then observed Fen Juechen and his actions.

The two started to converse, and Yun Long immediately noticed that Fen Juechen had clearly been convinced by Ye Mufeng, since Fen Juechen extended his hands out, listening to Ye Mufeng instructions, he unlocked the Soul Sealing Coffin using the pitch-black key Yun Long stole from Fen Yujie.

Bright lights from a formation appeared, as a rapid mist appeared from the Soul Sealing Coffin, until an eerie wind blew from every direction as the Soul Sealing Coffin blasted open, Ye Mufeng, the residing soul within the coffin, started laughing crazily as he pierced himself into Fen Juechen's soul world with no remorse for his saviour.

"Hehe… you are quite pitiful Ye Mufeng… almost as pitiful as my grandfather…" Yun Long thought as he knew Ye Mufeng was about to die to his son… or his reincarnated son…

Blood leaked from Fen Juechen's seven orifices, Fen Juechen's body had started shaking due to the intense pain and agony he felt, both mentally and physically, which caused Yunlong to slap his forehead, since Yun Long had overlooked that the one that had devoured Ye Mufeng in the original timeline, was the older, more tempered Fen Juechen… thinking of this he prepared one last gift for Fen Juechen.

"Ye Mufeng… the person you are trying to devour is the son of Ye Jianxi…" Yun Long said as his words were nearly interrupted by the heart-breaking screams Fen Juechen was letting out, but those words caused Ye Mufeng to pause, before his mind started to deteriorate due to his words, the sudden ŀȧpse in concentration allowed Fen Juechen's resistant soul to now possess the advantage.

"It would be in your best interest to allow yourself to be devoured Ye Mufeng…" Yun Long said once more as he prepared to silently weaken his soul, if he was not obedient.

"What… what did you say… he is… Huang'er?" Ye Mufeng muttered as he ceased his soul invasion, he then searched for something in Fen Juechen's soul, what he found made him laugh in madness, before he completely allowed Fen Juechen's to ȧssimilate his soul with no resistance, Fen Juechen was unaware, so he completely devoured his soul, since Ye Mufeng took the initiative to ȧssimilate his memories and residing special soul power onto his son's soul.

"Listen to me Huang'er, you are the prince of my Eternal Night Royal Family, the last of my Eternal Night Royal Clan's lineage and hope… I wish you live a good life, seize back my clan's Heavenly Sin Divine Sword, re-establish the Eternal Night Royal Clan, and take revenge for your mother… for all of your clan members… and for your very own self… You must take revenge… Never forget to take revenge!!!" Ye Mufeng shouted his final words as his soul got devoured, his words resounded within Fen Juechen's soul world, who was currently ȧssimilating the memories that Ye Mufeng had accumulated over his thousands of years during life.

Once he completed the process, Fen Juechen fell to his knees, the tears did not stop running onto his cheeks, his current self... seemed lifeless, even his previous haggard and bloodied appearance was an improvement in comparison to his current self, yet the power he currently possessed was already head and shoulders above anything he could have possessed in the Profound Sky Continent.

When he finally had recovered slightly, Yun Long approached him, grabbing his shoulders, he helped him up off his knees and doused him in water profound energy to clean him up, he gave him some black robes to change in, before he moved to a safe distance and turning his back, "Change your clothes, once you are done we will have a nice conversation" Yun Long said as he waited next to the now empty Soul Sealing Coffin.

"You mentioned my mother before… how do you know of such things that happened a thousand years ago… you clearly are only my age…" Fen Juechen asked coldly, he would not trust this odd person who brought him here.

"Hmm… I am old enough to be your older brother… but do not judge a book by its cover, there are many beings over a billion years of age that look younger than me… like I said, I just know the details because my woman told me about them, unlike me she is old enough to be your mother's mother…" Yun Long said to him jokingly, but his light joke fell on deaf ears, Fen Juechen probably did not have the capability to laugh.

Ignoring his jokes, Fen Juechen took a good look at Yun Long, ȧssessing him, now that he was not being dragged all over the place whilst they were travelling, and even with his new powers he could not sense anything about Yun Long that made him slightly apprehensive, but Yun Long interrupted his thoughts when he started speaking once more.

"From now on you are Ye Huang, Fen Juechen died the moment you took over his body, and it is the name your mother gave you… as for your task your father left you,I forbid you from taking any revenge against the Mighty Heavenly Sword Region, until you gain enough strength, and if you cheat your way to strength, I will similarly cripple you so that your mothers wishes are accomplished, do you have any problems with that?" Yun Long asked him, although he was really just informing him how things were going to go down.

Hearing his words, Fen Juechen scowled, he had enough of this guy, so he started gathering his profound energy, that was until Yun Long pulled out Hong'er in her sword form, before he pierced his dantian with one quick stab.

He had only just received his powers, and his cultivation was within Yun Long's acceptable battle power even against his own sealed cultivation, so he finally felt good that he could defeat someone with his own cultivation.

"Your mother sacrificed her life so that you can live a good life, so I will not let your revenge-crazed father ruin her wishes, after all he was not the one who had saved Bingyun in the past" Yun Long said as he looked at the unwilling Fen Juechen who was under his foot, with no emotions.
