You, a tyrannical ruler, roam the heavens; you cannot understand my joy.

"girl."

Lu Zuo walked up to the Grand Master of Fate and asked, "Is this person the Lord of the Underworld, young lady, young lady?"

"what?"

"Oh……"

He called out twice before the Grand Master of Fate regained his senses and shook his head, saying, "This person is named Guo Shang, and is the number two figure in the Netherworld Pavilion."

"His status is equivalent to that of the Eastern Lord in my Yin-Yang School."

Lu Zuo pressed further, "What about the Lord of the Underworld?"

His main purpose in coming here was to find this "Emperor of the Underworld" and the "Yellow Emperor's Yin Fu Jing".

"He took the Moon Goddess to the realm of Yin and Yang."

The High Priestess pointed to a distant mountain peak and said, "It's on that mountain."

Lu Zuo asked, somewhat puzzled, "What's he going there for?"

The Grand Master of Fate explained, "The so-called Yin-Yang boundary is actually a mountain cave, which is also the place where that Taoist sage secluded himself for cultivation back then."

"But his true identity is..."

A short while later.

Lu Zuo learned a secret of the Yin-Yang School from Da Siming.

That ancient Taoist sage secluded himself in the "Yin-Yang Realm" for ten years, comprehending the principles of Yin and Yang and the wonders of the Five Elements. From then on, he broke away from Taoism and founded the Yin-Yang School.

He was the founder of the Yin-Yang School!

Among the techniques created by the founder of the Yin-Yang School, the strongest is not the Soul Dragon Soaring Technique, nor the Eight Yin Meridians Curse, the Eight Yang Meridians Curse, the Five Elements Secret Technique, etc.

Instead... the Star-Picking Technique!

Although this skill has been passed down, no one has been able to master it to this day.

Therefore, successive leaders of the Yin-Yang School would often come to this cave to study the process of their ancestor's creation of the techniques engraved in the cave, and to learn from his insights...

However, the seal script is a secret language of Yin-Yang philosophy, and it is incomplete, so even if outsiders see it, they cannot understand it.

This is why the Yin-Yang School chose to serve the Qin Dynasty and temporarily reside on Zhaixing Mountain.

"The only ones who know the secret code are the successive leaders of the Yin-Yang School."

"But the Lord of the Underworld is going to the Yin-Yang Realm today, so he must also know how to break the secret code."

The Grand Master of Fate said with a worried expression, "The most urgent matter is to ask the King of Qin for help and request that he send a large army to encircle and annihilate us. Otherwise, with the power of the Lord of the Underworld, we..."

Before she could finish speaking, she sensed something was wrong and quickly looked up, only to find that the space beside her was empty; Lu Zuo was nowhere to be seen.

Looking up again, Lu Zuo had already arrived at the foot of the mountain and was rapidly teleporting upwards.

"This guy is too impulsive!"

"What kind of person is that Netherworld God Lord? How could you possibly contend with him?"

……

At this moment, inside a cave called the Yin-Yang Boundary.

"Has the senior gained some insight?"

A woman wearing a light blue dress, with dark purple hair and a thin veil on her face spoke softly.

Her voice was ethereal and otherworldly; though she was speaking right beside you, it felt as if she were a world away.

A tall, imposing man stood silently beside him, not replying, but gazing intently at the stone wall.

This person was dressed in a dark blue long robe, with hair as white as snow and frost. His features were like carved peaks, with deep and sharp contours. His aura was calm and composed, like an ancient well or a cold pool, or a majestic mountain, exuding an inexplicable majesty in his composure.

The stone wall is covered with intricate carvings.

These marks resemble handwriting, yet they also look like random scribbles, completely lacking any structure.

"The strokes are connected like the orbits of stars, and the turns are like the rushing of rivers."

The tall man spoke in a deep voice: "The handwriting is sometimes continuous like clouds, sometimes broken like lightning..."

"Moon Goddess, there's no such thing as a secret code, is there?"

"The patriarch attained enlightenment here. The marks on the stone wall are merely scratches left when he was deducing and practicing the 'Star-Picking Technique'."

The Moon Goddess was slightly taken aback, then nodded and said, "Senior's comprehension is truly exceptional, beyond comprehension."

"Oh."

The Lord of the Underworld chuckled: "If one truly possesses exceptional comprehension, one can glean some insights from the traces left by the patriarch."

"well……"

The Moon Goddess sighed softly, "I originally intended to use a secret code to break the spell, thus preventing you from getting lost here."

"I never expected that you would see through the clues in just a few hours."

She paused, then looked up and asked, "Senior, we are of the same lineage, do you really intend to exterminate us all?"

"Won't."

The Lord of the Underworld turned around and strode towards the cave entrance: "I will leave you here."

This……

The moon goddess parted her red lips slightly, as if she wanted to say something, but in the end she didn't utter a single word.

"Alas, the situation is what it is, there's no point in saying more."

"It's all about timing and fate..."

She sighed softly and was about to take a step to leave the cave when she heard the voice of the Netherworld God.

Who are you?

The Moon Goddess looked towards the cave entrance, but her view was blocked by the figure of the Netherworld God, and she could not see what was happening outside the cave.

"My name is Lu Zuo. Are you the Lord of the Underworld?"

A gentle male voice came from inside, which greatly surprised the Moon Goddess.

It's neither Xiangfei nor Donghuang Taiyi, could it be a master sent by the King of Qin?

"That's right."

The Lord of the Underworld nodded, his gaze sweeping over Lu Zuo a few times, his tone tinged with contempt: "Your imposing manner and the sharp blade in your hand, do you perhaps intend to fight me?"

Lu Zuo answered directly with his actions!

He stomped his feet on the ground and shot out like a fleeting glimpse of a swan, instantly appearing before the Netherworld God Lord.

Tsk!

The Demon Blade Thousand Blades tore through the air, piercing straight up towards the Netherworld God's jaw!

"Oh?"

"The speed isn't slow..."

The Lord of the Underworld raised his eyebrows slightly, seemingly surprised, but his figure had already taken half a step back before the words were spoken.

The blade grazed his cheek before piercing empty air.

In that very instant!

Crackling sounds...

A series of fine, crisp cracking sounds suddenly burst forth from the blade!

The long sword suddenly disintegrated between the two men, turning into thousands of fragments that shimmered with a cold, eerie blue light, like a metal storm that gushed towards the face and chest of the Netherworld God Lord!

Such a close-range attack is impossible to dodge, no matter how high one's martial arts skills are.

In an instant!

The shards rained down on his body, from his face to his chest, blooming into a horrifying patch of blood, leaving his upper body riddled with bloody welts...

As the Lord of the Underworld retreated, the Moon Goddess had already spotted Lu Zuo through the gap.

"With just one strike, the Lord of the Underworld suffered a great loss?"

"Who is this kid?"

Won?

Lu Zuo was slightly surprised. How could the dignified Netherworld God Lord, a master on par with Donghuang Taiyi, be killed with a single strike?

"Hehehehehehe..."

Just then, a low laugh drifted over.

The Netherworld God Lord slowly straightened up from his backward lean, and the bloody holes on his face and chest healed at a speed visible to the naked eye. Even the spurting blood was reversed and returned to his body through the wound.

"Interesting, interesting..."

"Since I mastered my skills, I have never suffered such a great loss in a single encounter."

Is this guy even human?

Looking at the scene before him, Lu Zuo thought to himself, "An existence that cannot be killed..."

"The two 'underworld emperors' seem to be the same person."

"Or rather, it's the same lineage!"
