Humans cover the sky, fishing for all the heavens.

While everyone else was trying to understand the imprints of the two, only Black Emperor was ranting:

"Damn it, a bald guy and an old man riding an ox are scribbling all over the place! It's so disrespectful to the Great Emperor Wushi!"

Ye Fan's lips twitched. The thought that these two sages were actually addressed by the Black Emperor in such a way made him want to rub the Black Emperor's head with the sole of his shoe.

Shi Feng smiled: "These two are at the ninth level of Quasi-Emperor, and they are still alive."

Black Emperor immediately wilted: "Never mind what I said."

"I feel I have a special connection with these two seniors, and I hope we will have the opportunity to meet in the future."

Shi Feng said, "Black Emperor, you don't want them to know about the insults you just said to the two quasi-emperors of the Ninth Heaven, do you?"

"Don't even think about taking my treasure, there's nothing there!"

Black Emperor, displaying a thick skin, retorted, "Their cultivation is so high, they definitely won't bother with me. Besides, they've insulted the Great Emperor Wushi; I'm the Great Emperor Wushi's dog!"

Shi Feng chuckled. The Black Emperor really had a thick skin; it was hard for him to get any gold coins.

Gai Jiuyou led a few people to the top, where a hundred-zhang-long coffin hung on the edge of the sacred cliff. The secret of the Xingzi was located here.

"Is this stone coffin moldy? It's covered in moss."

Black Emperor was suspicious, but upon closer inspection, he discovered that it was dense green hair growing out of the coffin and completely engulfing it.

He was so frightened that his whole body went cold, and he tucked his tail between his legs and ran behind Gai Jiuyou.

"Could the Great Accomplished Holy Body be a corpse that has turned into a zombie?!"

Ye Fan was also feeling uneasy. Shi Feng had told him that this was how the Holy Body would be in its later years: either green hair or golden hair would grow, and it would definitely grow hair eventually, making its later years an ominous sign.

Beside the coffin, the marks of Lao Tzu and Shakyamuni remain, along with two intricate star charts, densely packed with stars.

Every star chart has a thin, almost invisible line that points to the depths of the starry sky.

"They seem to be speculating about something."

Ye Fan's heart skipped a beat. Could this be the Ancient Star Road? Perhaps it could lead him home.

He silently memorized these two star charts.

The little girl gestured in the air with her tiny finger:

"Two small dragons are swimming..."

Her vision is unique; she can see the evolution, meandering, and stretching of two thin lines.

Gai Jiuyou was too lazy to wait for them to slowly memorize the star charts. With a flick of his hand, he transmitted the two star charts into their minds.

He looked at the coffin, then slashed away all the green hairs and opened the coffin directly.

In an instant, an overwhelming killing intent emanated from him, chilling and terrifying, making one's hair stand on end.

A terrifying aura swept out, causing the earth and mountains to tremble violently. More than fifty peaks around the sacred cliff shook violently, as if they were about to collapse.

The array patterns of the Great Emperor Wushi revealed supreme mysteries, with strands of silk spreading and intertwining in the void, eventually binding the ancient coffin together.

Halfway up the mountain, a burst of dazzling golden light suddenly erupted from the Investiture of the Gods, stabilizing the restless ancient coffin.

Gai Jiuyou protected the group; otherwise, they wouldn't have been able to withstand the killing intent alone.

The ancient coffin fell silent, and a Dao diagram lay horizontally in the void, extremely clear, as if descending from the ninth heaven, inspiring awe from the bottom of one's heart, making one want to kneel on the ground.

"This is the secret of the character '行'!"

Their eyes lit up immediately, and they quickly began to study the Dao diagram in the sky.

Before long, the big black dog grumbled, "This is a secret technique created for the human race, requiring two legs to walk. Does this emperor have to transform into human form to cultivate it?"

Shi Feng stared at the Dao diagram, immersed in comprehension. He was doing alright at the basics, but it was impossible for him to comprehend the secret of the word "Xing" on the spot. The secret of the word "Xing" involved the realm of time and was extremely difficult and obscure. There was once a saint who took the elixir of immortality and lived two lifetimes before he reached the ultimate level of cultivation.

This is not a magic formula that can be achieved overnight.

He etched the Dao diagram in his mind; once it was memorized, he could gradually comprehend it.

"Although both are wonderful techniques in the field of speed, they are very different from the Kunpeng Treasure Technique."

Shi Feng compared the two methods.

The Kunpeng Treasure Technique elucidates the transformations of Yin and Yang, and embodies the wondrous spirit and form of the Kunpeng.

The "Xing" character secret involves changes in the time domain.

These two do not overlap; instead, they can be combined to increase speed, allowing the user to break through to a level that is difficult for others to reach.

Once he masters both, he will become the true fastest, surpassing even the carefree Celestial Venerable who created the Xingzi Secret.

"Haha, I've succeeded!"

The Black Emperor stood upright, took off running on its hind legs just like a human, its body still shedding fur.

"Who says dogs can't learn human secret techniques? From now on, I'll walk on two legs!"

"This actually works?"

Ye Fan was utterly shocked. "Even a dog can master the 'Travel Word Secret'?"

"What, you're not convinced?"

The Black Emperor's legs moved swiftly, becoming a blur. "Ye Fan, I don't think your Holy Body is all that impressive. Even as my concubine, you still hold your position as the number one warrior!"

Ye Fan ignored him, feeling utterly outrageous.

"How could I be inferior to a dog!"

"Do you really think the Black Emperor's cultivation level is only this low?"

Shi Feng said, "Baptized and carefully taught by the Great Emperor Wushi with his own blood, even a pig can become a saint. He has severed his past cultivation and started anew."

Ye Fan sighed, "The title 'Demon Saint' sounds impressive, but the thought that this dog used to be one makes it seem less prestigious."

The Black Emperor opened his blood-red maw, revealing gleaming, dagger-like teeth: "What grievance do you have against me? What is a Demon Saint? I will become the Demon Emperor, the Demon Immortal!"

Shi Feng lightly tapped his toes, and in an instant, he appeared behind Ye Fan, having also entered the realm of the "Word of Movement" secret technique.

"Ye Zi, perhaps the Ancient Sacred Body still lacks a little in comprehension."

Is it just slightly lacking?

Ye Fan was in tears. "I'm still holding the Bodhi seed in my hand!"

The little girl imitated the diagram and then vanished in a flash.

Ye Fan looked at Gai Jiuyou, not thinking at all that he hadn't grasped the concept, and sighed to the heavens, "I'm the only one left who hasn't learned it..."

"Waaah—"

The little girl appeared on the coffin lid, and she was so frightened that tears almost fell. "How terrifying..."

Several people rushed over and found the coffin filled with blood, a vivid, bright red, as if it had just flowed from a human body. An old man lay dead inside, floating on the blood.

His physical body was immortal, and he held a golden scepter, emanating an unparalleled killing intent that could pierce through a person's soul.

"He was just a saint."

Gai Jiuyou said, "With such a strong killing intent, he must be the Lord of Heaven."

"The Lord of Heaven? What a grand name."

Ye Fan asked, "How come he's just a saint?"

"It is not the Heavenly Court of mythology, but the Heavenly Court of Assassins. The Assassin Dynasty has three major organizations: Heavenly Court, Hell, and the Human World. Heavenly Court was once the largest assassin organization, and the Xingzi Secret is their legacy."

The name "Heavenly Court" was simply too grand to command respect. All Heavenly Courts established throughout history have crumbled; none can endure. The Assassin Heavenly Court was no exception, and it was ultimately destroyed by a combined force of various holy lands, Hell, and the mortal realm.

Black Emperor explained,

"Legend has it that the Lord of Heaven died here after his lifespan was exhausted. He was killed in the final battle, but unexpectedly, he died here with the secret of the character '行' in his body."

He was somewhat horrified: "His neck had been broken."

The neck of this last ruler of the Heavenly Court was broken, with clear fingerprints and some green hairs on it.
