The eighty-fourth volume of the "Cloud Abode Seven Chapters" cites the "Red Book Jade Formula" saying: Ingest the breath of the five directions five times each, merging into twenty-five swallows, then stop. Practice this path for nine years diligently and sincerely, without negligence, and the true deity will manifest in form. A staff can then carry a person to travel through the air. If wishing to perform the corpse liberation, the staff can substitute form, and in an instant, transform one into a True Person. This is called 'Staff Dissolution'.

The eighty-fourth volume of the "Cloud Abode Seven Chapters" in the "Corpse Liberation Sequence and Method" discusses the 'Path of Sword Liberation for Corpse'. It describes inscribing Qu Chenfei's delicate swordsmanship on both sides of a book, first feigning illness, then lying down with the sword, which is called 'Sword Dissolution'.

Although the Corpse Immortal is considered a lower tier, Zhang Sanfeng's willingness to assist me with Lv Zu's precious sword for sword dissolution does grant me some dignity,

given his Taoist practice, becoming an Earth Immortal should not be difficult."

Sun Biyun, perhaps not having spoken to anyone for many years, began to speak endlessly once he started.

However, it was quite normal, as he said, for over 600 years, Wang Longhu has been the only one capable of sensing his presence.

Before this, even if he desired to communicate, others could hardly perceive him.

Only someone like Wang Longhu, who has the Three Elixirs Dantian Condensed Pill and possesses the Sixth Sense, could do so.

"So it seems that the immortality of a Corpse Immortal is no different from a Ghost Immortal, merely a method for one's consciousness to persist in this world." Wang Longhu thought to himself.

But this action is indeed a helpless lower path, losing the physical body, and even if the soul can rely on the object of corpse liberation, what of staying in this world forever?

Being able to keep the physical body in the world forever, that is the true great path, akin to what Sun Biyun referred to as Celestial and Earth Immortals.

"Are you wondering what power I still have in this form?" Sun Biyun suddenly smiled as he noticed Wang Longhu lost in thought.

Wang Longhu was too lazy to lie and directly nodded, "Can you show me, Master Daoist?"

"It's been over 600 years, since someone wants to see it, I'll show it to you." Sun Biyun smiled, raising his hands to form mystical seals.

At the same time, on the cliff face of Wudang's Nanyan Palace, a longsword that had gathered dust for centuries unexpectedly moved without wind.

It vibrated slightly on the cliff face, and the next second, the longsword broke free from the iron restraints, pierced the sky, and shot towards the summit of Celestial Pillar Peak.

Wang Longhu, initially focused on Sun Biyun, suddenly changed his expression as a surge of danger made him feel prickly.

"Behind!" Wang Longhu reacted instantly, turning around to deliver a punch.

Bam!

A sword blade, source unknown, collided with his fist, repelled by Wang Longhu's immense force, spinning continuously in mid-air.

Whizz!

The longsword turned in the air, approached again, targeting the center of Wang Longhu's brows.

Wang Longhu's pupils shrank, and he instinctively reached to grasp the near-forward sword, holding it firmly immobile in his hand.

"What a move of sword control! How did you accomplish that, Daoist Master Sun?" Wang Longhu praised in astonishment, examining the shallow bleeding sword mark on his fist.

With his current physique, even the sharpest blade shouldn't inflict any injury on him.

This Lv Zu's sword managed to produce a bloodstain, proving its extraordinary nature.

While Wang Longhu was amazed, Sun Biyun was equally surprised.

This kid could so easily catch a blade; his strength surpassed Sun Biyun's imagination.

In these 600 years, outsiders have attempted to target Wudang, but all were neutralized under his covert protection.

Since the sword dissolution involved this sword, Sun Biyun himself had no abilities and could only control the sword within a certain range.

And wherever Lv Zu's sword was, he could only be there, unable to go too far, so for 600 years, Sun Biyun remained at Wudang.

"Your strength is a bit beyond my comprehension," Sun Biyun sighed, dispersing the seals, causing Lv Zu's sword to cease motion in Wang Longhu's hand.

"I acknowledge that there's no one in the world today who could be my opponent. Master Daoist Sun need not feel disappointed." Wang Longhu released his grip, and Lv Zu's sword instantly flew back to rest on Wudang's Nanyan Palace's cliff face.

"Few have reached that stage through the ages; in 600 years, you're the only one I've met. If Zhang Sanfeng were alive today, I wouldn't know who might be stronger." Sun Biyun sighed.

A person like Wang Longhu, having reached the Condensing Pill stage of the Three Dantian, is indeed rare in history.

The previous one would be Zhang Sanfeng, and going further back, it becomes even more distant.

"Do you really believe this world contains someone who could live from the Ming Dynasty until now? Honestly, even though I fancy myself invincible now, despite my robust body, I dare not assure I'd live to 300 years,

as the great path has its limits. Even if a planet spans billions of years, unpredictably, it might be destroyed someday; even the great sun, given enough time, will extinguish,

ascending to immortality might indeed just be an embellished legend spanning millennia," Wang Longhu said.

Sun Biyun shook his head, "That, I do not know. Zhang Sanfeng told me before he left that he's reached the end of the road; if he stayed in the Central Plains, he'd only exhaust his vitality,

and he was going to search for a new path. Before him, two sages had already preceded him."

"Two people before Zhang Sanfeng? Who were they?" Wang Longhu was surprised.

"Master Ghost Valley and Li Er, also known as Laozi."

Wang Longhu fell silent, acknowledging that myths often accompany bits of truth.
