Immortality: Starting with a grave, I'm invincible when burying corpses.

"To construct a grotto-heaven world with endless thunder, and to generate all things in heaven and earth with the Great Dao of Thunder, this method... cannot be wrong. The being who created this precious pearl is at the same level as me."

Inside the small pavilion surrounded by flowing water, Mu An held a purple pearl in her hand, its edges constantly changing color, and examined it closely.

The surface of the jewel was covered with cracks, exuding an ancient and decaying aura.

It seems as if it had experienced a great calamity long ago, or as if it had been worn down by the passage of time, eventually collapsing.

Looking from the outside in, one can see countless purple-gold patterns hidden inside the pearl. These patterns are not inanimate objects, but are undergoing an extremely slow process of change, constantly moving towards destruction.

After observing for a while, Mu An put down the pearl and gave his conclusion.

"A product of the Golden Immortals, the being who created this bead is skilled in the Way of Thunder and Lightning, and has reached the realm of creating all things with thunder and lightning."

The celestial treasure possesses a spirit, but this pearl has long been damaged, and the cave within it is shattered and about to return to chaos. Furthermore, the spirit of the artifact was completely obliterated hundreds of thousands of years ago.

The crafting techniques used to create the pearl were not particularly sophisticated. Even if it remained intact and had never experienced any calamities, it could not withstand the erosion of time.

The refiner must have specialized in the art of lightning, lacking in other aspects, which led to the bead being overly aggressive and neglecting its protection. This is why the bead could not withstand the erosion of time and has become what it is today over the long years.

If this pearl had been obtained 300,000 years ago, before it shattered and while its sentience remained, it might have been of considerable use. But now… aside from a few scattered fragments of its Dao principles, it is utterly useless.

The old celestial master was not surprised by Mu An's conclusion. Although he had not reached the Golden Immortal realm, at his current level, he had some guesses about the existence of Golden Immortals and what kind of supernatural powers they possessed.

He had studied this precious pearl, brought down by an immortal from the "upper realm," countless times and reached similar conclusions.

Taking out this bead was merely a prelude to the real goal of this trip.

Under Mu An's watchful gaze, the old Celestial Master put the precious pearl on the table back into his sleeve, and then took out the Yin-Yang Taiji Diagram, the most treasured heirloom of the Four Symbols Mountain.

"Fellow Daoist, you might want to take another look at this item."

"The Yin-Yang Taiji diagram? Isn't this your Taoist sect's most treasured heirloom?"

Seeing the old celestial master take out the Yin-Yang Taiji diagram, Mu An's eyes narrowed slightly as he looked at the scroll before him.

Even without looking closely, he immediately noticed something amiss.

"Fellow Daoist, you brought this precious treasure to me. Is there perhaps something wrong with this map?"

The old master shook his head slightly, without explaining to Mu An, and instead pushed the Yin-Yang Taiji diagram directly to Mu An's side, letting him look at it himself.

Although the old master had already come to a conclusion, just in case, he did not tell Mu An the conclusions he had reached after years of continuous exploration.

The old Celestial Master knew that Mu An was no ordinary Golden Immortal; his realm of vision far surpassed that of the Nine Realms Heavenly Dao.

Although Mu An claimed to have just entered the Golden Immortal realm and said that he was only at the bottom of the Golden Immortal realm, the Old Celestial Master did not believe him at all and took it as a humble statement.

In the eyes of the old celestial master, Mu An was a high-ranking Golden Immortal, far beyond the reach of ordinary Golden Immortals.

If you ask why, it's because of my unparalleled intuition.

Xuanxian can act on behalf of the authority of heaven and earth, and is the strongest below Jinxian. The current Celestial Master controls 30% of the authority of heaven and earth in the Nine Realms, and his strength is beyond doubt.

If the complete Nine Realms can be considered a Golden Immortal, then the Old Celestial Master can be considered to possess the power of three-tenths of a Golden Immortal.

Perhaps the Celestial Master's life essence is still much inferior to that of a Golden Immortal, but in terms of pure power, there is no insurmountable gap between him and a Golden Immortal.

But in front of Mu An, the old celestial master's spiritual sense was constantly warning him.

That's why the old master was so certain about one thing.

Mu An is definitely not an ordinary Golden Immortal.

If there really is something wrong with the Yin-Yang Taiji diagram, it will definitely not escape Mu An's eyes. The old master did not want his own opinion to lead to preconceived notions and affect Mu An's judgment.

Just as the old Celestial Master had predicted, Mu An discovered the problem with this Taoist treasure after obtaining the Yin-Yang Taiji Diagram.

With just one glance, Mu An's gaze was fixed on the center of the Yin-Yang Tai Chi diagram. His pupils turned silver-white, and his vision pierced through layers of thick fog, reaching the deepest part of the Yin-Yang Tai Chi diagram.

"This is……"

Deep within the scroll, which is heavily surrounded by the laws of Yin and Yang, lies a faint spatial rift, and on the surface of this rift, which should not exist, lies an array that could collapse at any moment.

Even if the formation is set up in an extremely secretive way, concealing the spatial rift deep within the Yin-Yang Taiji diagram, ordinary people would have no way of discovering it.

But no matter how well it was hidden, it couldn't escape Mu An's sight.

"Interesting, very interesting! This Nine Realms isn't very big, so why is it so popular? Everyone wants to get involved!"

He murmured to himself, and then the silver light in Mu An's eyes intensified. Two silver-white beams shot out from his eyes and rushed straight into the Yin-Yang Taiji Diagram.

The instant the silver light rushed into the scroll, the Yin-Yang Taiji diagram seemed to be stimulated, and thousands of Yin-Yang fish rushed out from the depths of the scroll, crashing into the silver light.

Two completely different forces collided deep within the Yin-Yang Taiji diagram, instantly opening up millions of battlefields.

The Yin-Yang Dao and the Laws of Creation clashed on battlefields, collided at a seemingly slow but actually extremely fast speed.

The forces belonging to the Great Dao collided, dissolved and devoured each other, clearly indicating that they were forces at the same level.

However, the Yin-Yang Taiji Diagram, which controls the Yin-Yang Great Dao, is ultimately a rootless duckweed, far from being a match for Mu An when he gets serious.

Within a quarter of an hour, the Yin-Yang Taiji Diagram, having exhausted its strength, collapsed and could no longer organize an effective defense. It could only allow Mu An's power to rampage through its body, killing its way in and out seven times.

Across the stone table, the old celestial master, who had witnessed everything, revealed an expression of "I knew it," and even smiled at Qinghe, who was peeking out from behind the flower bushes.

The old master sat there calmly, watching Mu An "destroy" the treasure that rightfully belonged to him.

Whether the treasure was damaged or he was outmaneuvered, it did not stir up the slightest ripple in the Old Celestial Master's heart.

He even had the leisure to wave to Qinghe.

"This old Taoist is getting on in years, and we've been chatting for quite a while now, so I'm a little thirsty. Would you be so kind as to pour me and your husband a cup of spiritual tea? The tea leaves are already on the table; please help yourself."

Qinghe, who was hiding behind the flowers, was stunned for a moment, but quickly came to her senses. Still immersed in shock, the little girl stood up abruptly, nodding to the old master and muttering to herself.

"Tea, tea, tea... Yes! Hot tea... I'll make you some tea right away!"
