Holding a lantern, guiding souls across, Lady Hou comes from the underworld.

Mount Jiuxiao sounds like a place of ethereal beauty, but in reality, it is adjacent to the underworld.

As one of the Five Phoenixes, "Fengzhuo Clan" did indeed once reside in the Heavenly Realm, but unfortunately offended the Lord of Heaven and was banished to the Underworld.

Therefore, the once ethereal Jiuxiao Mountain has become the "Prisoner Phoenix Mountain," shrouded in perpetual mist and shrouded in darkness.

The two messengers of impermanence led everyone down the mountain and then said, "Feng Zhuo is on the mountaintop. Ten years ago, she infiltrated the Underworld and stole the Earth Lord's musical score..."

Wuyou couldn't help but mutter, "Why did the Earthly Lord only demand repayment today after all this time?"

The two messengers couldn't really explain it either, but they still glared at it, "Why ask so many questions? Think about how to get the sheet music!"

Yan Zhengchu said, "Even if we have to rob it today, we will take it back."

Of course, Wuyou knows more about the affairs of the underworld.

After the two messengers of impermanence left, it said, "I've long heard that this Phoenix Clan member has an extremely bad temper; otherwise, she wouldn't have angered the Lord of Heaven. Moreover, there was a time when she enjoyed eating evil spirits, especially those from the Nine Nether Hells!"

Upon hearing this, Yan Zhengchu realized that this trip was not simple. He said, "Luckily, we're not evil spirits!"

Mo Gu suddenly said, "I am."

"..."

And you know what? She was once the most notorious evil spirit in the Nine Nether Hell.

Ren Fengjue took her hand and said calmly, "Let's not worry about the situation for now, let's go there and figure out a solution."

Mount Jiuxiao is high and dangerous, but there is no road. To reach the top, one must either use soul power to fly or borrow magic to fly.

Yan Zhengchu had already devised a plan: he would fold yellow talismans into paper cranes, which would carry the soul upwards.

But after he finished folding the paper cranes, he found that there was no one beside him.

Ren Fengjue didn't wait for anyone and followed Mo Gu directly, taking Wuyou, who was inside the Soul Ferry Lamp, with him.

Yan Zhengchu cursed them for being unrighteous, and immediately activated his magic, riding a paper crane and taking off into the air.

Before long, a dilapidated palace came into view, with no nameplate and only the sound of the wind swirling around.

Ren Fengjue and Mo Gu were standing in front of the palace gate waiting for him.

Master Yan looked at the two of them and couldn't help but let out a muffled groan.

Ren Fengjue offered an explanation: "Mogu said it's faster to follow her."

Yan Zhengchu glanced at their tightly clasped hands and snorted again.

He put away the paper crane and was about to push open the door when a sharp, piercing cry came from all directions.

Wuyou covered her ears and reminded her, "I heard that the cry of the Phoenix Clan is her most powerful 'weapon'."

Yan Zhengchu also found the sound extremely unpleasant and couldn't help but wonder, "I never knew the cry of a phoenix could be so awful!"

No sooner had the words left his mouth than a huge black shadow loomed over him from the sky.

Mo Gu saw that the black shadow's target was clearly Yan Zhengchu, so he immediately pushed him aside.

After everyone dispersed, they discovered that it was actually a huge black phoenix.

"Where did these wandering ghosts come from, daring to come to my Nine Heavens Mountain?"

"Black Phoenix" cried out again, this time its voice resounding throughout the heavens.

Fearing their eardrums would be ruptured, everyone hurriedly covered their ears.

Seeing this, "Black Phoenix" smiled contemptuously, and with a flap of its wings, a gust of wind swept over.

Yan Zhengchu quickly used his jade sword to steady himself, while Ren Fengjue also grabbed Xia Ximo's hand and supported his jade sword with his other hand. Wuyou also hurriedly crawled into the Soul-Crossing Lamp.

The three of them struggled to maintain their footing amidst the strong winds, and they realized that it would be difficult to snatch the musical score back from Feng Zhuo.

As "Black Phoenix" flapped its wings, it also sized up the three of them, then suddenly its eyes narrowed.

Why would the Nine Nether Souls be mixed up with two wisps of living souls?

Clearly, she also noticed something was wrong.

Yan Zhengchu was about to explain, "We came here to..."

"Black Phoenix" scoffed and immediately interrupted him, "I'm not interested in you..."

Then, the claws pointed at Mo Gu, "I'm only interested in her."

Seeing this, Ren Fengjue immediately drew his sword and shielded Mo Gu in front of him.

"Black Phoenix" glanced at Ren Fengjue again, seemingly curious, "You're just a wisp of a soul, what do you have to do with this Nine Nether Soul Imprisonment? Why are you protecting her?"

Ren Fengjue replied, "She is my wife."

"Black Phoenix" reacted as if she'd heard a hilarious joke. "Wife? You actually married a demon? Aren't you afraid she'll devour you alive, leaving not even bones?"

Although Wuyou was afraid, she still peeked out from the lamp and cautiously spoke up for Mogu.

"Not all souls imprisoned in the Netherworld are evil spirits!"

"Yeah?"

"Black Phoenix" replied lazily, "Then I'd like to see how she differs from the other evil spirits of the Nine Netherworlds."

After that, another piercing cry rang out.

"Black Wind" flew towards Mo Gu and opened its equally sharp beak, seemingly wanting to swallow it whole.

At the same time, Yan Zhengchu and Ren Fengjue made their moves simultaneously, and the white light from their two jade swords almost pierced through the dark mist on Mount Jiuxiao.

However, this is the underworld after all, and as souls, they are simply not able to unleash the true power of the jade sword under such circumstances.

Therefore, even if they attacked at the same time, they were quickly defeated in front of this "Black Phoenix".

Wuyou said worriedly, "Mogu, they are definitely no match for the Fengzhuo Clan!"

Mo Gu could see it too. Although the Earth Lord had taken away 60% of her soul power, the Yin energy in the Yin Realm was abundant, and her soul was free and stronger than when she was in the human world.

So she immediately used the Bone-Fixing Technique to restrict the "Black Phoenix's" attacks.

"Black Wind" hadn't expected her to use this move, and immediately vanished into nothingness, merging with the dark mist.

In this way, bone magic would be unable to control her.

The next second, a woman in black with a seductive figure appeared behind Mo Gu.

Wuyou sensed her presence and immediately shouted, "Mogu, watch out!"

Mo Gu reacted extremely quickly, shifting his position swiftly with a sway of his body.

However, she was fast, but "Black Phoenix" was even faster. The two shadows, one red and one black, moved with lightning speed, dazzling the eye.

Ren Fengjue and Yan Zhengchu saw this but couldn't do anything about it and could only worry anxiously.

After exchanging a few blows with Mo Gu, "Black Phoenix" was slightly surprised, having figured out her bone technique.

She said, "Little girl, your magic can't do anything to me. My primordial spirit is still in the Heavenly Realm. This place is just where my physical body is imprisoned. And what you see now is just an illusion."

After saying that, she vanished without a trace.

Yan Zhengchu and Ren Fengjue quickly went to Mo Gu's side, and only when they saw that she was unharmed did they feel relieved.

Mo Gu glanced at the palace next to him and said, "Let's go in and take a look."

With everyone's combined efforts, they pushed open the heavy palace gate, and what came into view was a giant stone statue of a phoenix.
