The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

"What the hell is this thing?" Shen Yifei took three steps back, and with a sweep of his Long Sky Sword, a black sword aura cut the gray mist in half.

But the gray mist dispersed and then gathered again, as if it were alive, and could not be killed at all.

The phantom figure let out a piercing laugh: "Boy, your swordsmanship is not bad, but it's nothing compared to mine!"

Shen Yifei cursed inwardly and was about to summon Ye Ling to help when the red aura in his dantian suddenly became restless, as if it had sensed something.

The illusory figure seemed to sense Shen Yifei's abnormality, and its laughter abruptly stopped. "You... what's that inside you?"

"Guess?" Shen Yifei grinned, and without further ado, he condensed a ball of red energy in his palm and flung it directly at the illusory figure.

The red light landed on the phantom and exploded instantly!

"Ah..." The phantom let out a shrill scream, and the gray mist seemed to be ignited, making a "sizzling" sound.

"Ah... Demon God... Five Elements Demon God..." the phantom screamed as it cried out.

Shen Yifei was shocked. To this day, apart from him and Ye Ling, this was the first person, no, the first thing to know the aura of the Five Elements Demon God!

"What are you? Do you know about the Five Elements Demon Gods?"

As Shen Yifei asked, he conjured another ball of red light in his hand, even larger than the previous one!

The crackling sound from the phantom gradually disappeared. It dared not approach Shen Yifei and squatted in a corner of the room, clearly trembling.

"What exactly are you? Why do you know the Five Elements Demon God?" Shen Yifei took a step forward, and the red light in his hand shone even brighter.

The phantom vaguely revealed a distorted face in the gray mist. The face constantly changed shape, sometimes like an old man, sometimes like a child, sometimes like a woman, and sometimes like a wild beast.

"You...you shouldn't possess this power...it's the power of the ancient Five Elements Demon Gods...it's forbidden..."

"Forbidden?" Shen Yifei scoffed. "I bet it's a power specifically designed to counter filthy things like you, isn't it? I'll ask you one more time, how could you recognize the power of the Five Elements Demon God?"

"The Five Elements Demon God... that was one of the nine great demon gods at the beginning of time... both righteous and evil... power... power should not be in the hands of mortals..."

"You say the Nine Demon Gods are both righteous and evil, so what about you? What are you? Being able to know the Five Element Demon Gods, you're not exactly an ordinary person, are you?"

"Hmph, I... I am also one of the nine great demon gods, the Soul-Devouring Demon God!"

"You're the Soul-Devouring Demon God?" Shen Yifei looked the trembling gray mist up and down. "With your cowardly appearance, you dare call yourself a demon god?"

The illusory figure twisted in anger at his words, its voice distorting: "Boy, what do you know! I'm just a wisp of a remnant soul, my power hasn't recovered yet! In the past, I could have blown you to dust with a single breath!"

"Blow it to dust?" Shen Yifei chuckled. "Then you try blowing it for me first! I'll stand right here and I promise I won't move!"

Enraged by his words, the phantom writhed violently, the gray mist twisting and contorting, making its face even more ferocious.

"Boy! Don't be so smug! Although I am but a remnant soul, I am not someone you can insult!"

"You're still being stubborn, using the name of a demon god to commit evil deeds. I'll show you what a demon god really is today!"

After Shen Yifei finished speaking, he made a gesture as if to smash the ball of red light into the phantom.

"Ah..." The phantom screamed, startling Shen Yifei and Mo Ran.

"What the hell are you yelling about?!"

Shen Yifei cursed irritably, the ball of red light in his hand swayed, and the phantom trembled again in fright, shrinking into the corner and not daring to make a sound.

Mo Ran hid behind Shen Yifei, looking at the illusory figure that was arrogant and domineering just now but was now as cowardly as a dog, and couldn't help but chuckle.

"What...what are you laughing at!" The phantom was furious but dared not retaliate, and could only shout a weak and intimidating remark.

"I'll ask you one more time, what exactly are you? How did you recognize the aura of the Five Elements Demon God?"

The illusory figure remained silent for a long while before slowly speaking: "I...I am a soul servant under the Soul Devouring Demon God, ordered to collect the souls and inner demons of cultivators in the Northern Underworld to nourish the remnant soul of the Soul Devouring Demon God."

"The Soul Eater Demon God's Soul Messenger? The Soul Eater Demon God is also one of the Nine Great Demon Gods?"

"Yes." The illusory voice carried a hint of arrogance, but it quickly waned. "The Soul-Devouring Demon God is one of the nine great demon gods, the one who governs the souls and inner demons of all things in the world. Back then, the Soul-Devouring Demon God was severely injured, leaving only a wisp of his soul, which slumbers deep within the territory of the sea monster race."

"The territory of the Siren Clan?" Shen Yifei's heart skipped a beat. "Are you Soul Devouring Demons in the Siren Clan's territory?"

"Yes." The illusory figure nodded, a fawning smile appearing on its blurry face. "Young master, you possess the aura of the Five Elements Demon Gods, and you are all destined to be with them. If you release me, I will put in a good word for you before the Soul Devouring Demon God. When the Demon God awakens, you will surely receive your due reward."

"A few kind words?" Shen Yifei chuckled. "Do you think I'm a fool? You just wanted my body, you wanted to blow me to smithereens, and now you want me to let you go?"

The illusory figure chuckled twice. "Misunderstanding, all a misunderstanding. I... no, I was blind to your greatness, unaware that you possessed the aura of the Five Elements Demon God. If I had known you were the successor of the Five Elements Demon God, how dare I have attacked you?"

"You've got a good tongue, kid. Tell me, where is the Soul-Devouring Demon God in the Siren Clan? And how do we find him?"

The illusory figure hesitated for a moment, seemingly unsure.

Shen Yifei waved the red light in his hand. "Fine, you don't have to talk about it. I'll send you on your way now."

"No, no, no! I'll talk, I'll talk! I was also captured by the Soul Devouring Demon God to work for him. My life is worthless."

The phantom hurriedly said in fright, "The remnant soul of the Soul Devouring Demon God is in the Abyss of the Sea Demon Clan's sacred land. That place is in the deepest part of the Sea Demon Clan's territory, and ordinary people cannot enter. However, since you possess the aura of the Five Elements Demon God, the restrictions there should be of little use to you."

"Mingyuan?" Shen Yifei memorized the name. "You just said you were collecting cultivators' souls and inner demons? Mo Yu's soul and inner demons, were they collected by you?"

"Yes...yes." The illusory voice grew softer and softer. "This young master...no, this young master Mo Yu, he was preoccupied with worries after returning, and his inner demons were growing, which made him my target. I took advantage of his unstable state of mind to invade his consciousness and take control of his body."

Shen Yifei turned his head and glanced at Mo Yu, who was slumped in the chair.

Mo Yu's face was still pale, but the gray mist had completely dissipated. He closed his eyes, breathing evenly, as if he were asleep.

"Is he alright?" Shen Yifei asked.

"It's nothing, nothing. His spirit is just a little weak. He'll be fine after a few days of rest. I only temporarily controlled his body; I didn't harm his fundamental health."

Shen Yifei nodded, reached out and checked Mo Yu's pulse. There was nothing seriously wrong, just a little weak.

He stood up, looking at the illusory figure. "How much power do you have left?"

The illusory figure gave a wry smile. "I am but a wisp of soul, and my power is not much to begin with. I was injured by your Five Elements Demon God power just now, and it's good enough that I can maintain my form."

"Alright, I'll spare your life." Shen Yifei put away the red light in his hand. "Take me to the territory of the Sea Demon Clan, find the Nether Abyss, and find the Soul Devouring Demon God. After it's done, I will not only release you, but I can also help you repair your damaged soul."

The illusory figure paused, then asked, "You...you're telling the truth?"
