Chapter 633: The Infinite Grand Dao

An Xin stared at the black flame figure, too frightened to utter a word, fearing that even the slightest sound would disturb it.

The figure had appeared without any warning. An Xin had been completely unaware of its presence until it materialized. Now, just looking at it sent a chill down her spine.

Even though her Immortal Emperor’s Pupil had improved, merely gazing at the figure made her heart pound violently.

It was an instinctive reaction to overwhelming danger—at first glance, she could tell that she was absolutely no match for this entity.

However, she soon realized something.

The figure did not seem to notice them.

She turned to look at her master and saw that Gu An remained calm, his expression composed as he silently observed the black flame figure and the cultivator it was pursuing.

Even the cultivator being suppressed by the black flame figure carried an unfathomable aura, making An Xin feel that he, too, was someone beyond her understanding.

"Master, what is the cultivation level of the one being pursued?"

An Xin couldn't suppress her curiosity and asked.

Gu An answered calmly, "Vast Heaven Free Immortal, a realm above Profound Origin Free Immortal."

Vast Heaven?

An Xin was taken aback.

She knew that above the Free Immortal Realm was the Dao Fruit Realm, and that Profound Origin Free Immortal was considered the peak of Free Immortal Realm within the Heavenly Spirit Great World. Even the ruler of the Dao Court had only reached this level.

Yet now, an existence even stronger than the Dao Court’s master was being completely overpowered by an unknown entity, unable to display any of the power expected of a Vast Heaven Free Immortal.

An Xin quickly followed up, "Then what about the existence behind him? What realm is that?"

Gu An replied, "Innate Golden Immortal Realm, a stage above Vast Heaven Free Immortal, the first realm of Golden Immortal Dao Fruit."

Innate Golden Immortal!

An Xin’s eyes widened with astonishment.

"The higher one's cultivation, the harder it is to fight across realms. In the future, if you encounter someone of a higher realm, the best course of action is to avoid them rather than trying to force a battle," Gu An advised her solemnly.

This battle was no coincidence. Gu An had already foreseen that such a battle would occur near the Ethereal Immortal Court, and he had intentionally brought An Xin here so she could witness it firsthand—to understand just how terrifying the world beyond hers could be.

The universe that housed the Ethereal Immortal Court was not part of the Grand Thousand Worlds. It was even vaster, and the Grand Dao Rules here were more condensed and profound.

Through his calculations, Gu An had determined that such universes were known as Grand Dao Universes, which were ranked above the Grand Thousand Worlds.

"Don't worry, Master. I won't go wandering off on my own. I'll stay by your side and continue cultivating," An Xin said with a playful smile.

She didn’t find training beside Gu An dull at all. In fact, she thoroughly enjoyed the feeling of constantly growing stronger.

Moreover, she could observe the rise and fall of the mortal world from here. If she ever wished to explore, the Qiankun Sect would be an ideal place. Within the sect, she could experience the world's changes and witness new wonders every year.

At that moment—

The black flame figure extended its hand.

With just a single touch to the Vast Heaven Free Immortal’s forehead—

The Vast Heaven Free Immortal was instantly reduced to ashes, erased from existence.

An Xin was shaken to her core.

No matter how high one's cultivation reached, there would always be an entity they could not contend with.

She couldn't help but wonder—

This black flame figure was merely at the Innate Golden Immortal Realm, yet it could not see her or her master.

Then, what realm was her master truly at?

It had to be higher than Innate Golden Immortal!

Gu An’s lips curled slightly.

Above Innate Golden Immortal was Measuring the Heavens Golden Immortal.

Beyond that was Supreme Purity Golden Immortal.

And even higher were Heaven-Opening Grand Luo Immortal and Wondrous Truth Grand Luo Immortal!

The difference between him and the black flame figure was far beyond An Xin’s comprehension—but he had no intention of revealing his true cultivation.

After annihilating the Vast Heaven Free Immortal, the black flame figure vanished into thin air.

"In a Grand Dao Universe, even the strongest existences must remain cautious at all times," Gu An remarked.

An Xin’s respect for Gu An grew even deeper.

Given Gu An’s cultivation level, he could easily erase the black flame figure, yet he never bullied the weak.

Compared to those powerful beings who acted recklessly, An Xin admired her master far more, for he was someone who could restrain his own desires.

Although her master enjoyed reading some rather questionable books, in An Xin’s eyes, he was the one who most resembled a true immortal.

He understood the ways of the world but was not bound by them. He embodied the essence of an immortal without the arrogance of one.

She would never forget the words her master once told her.

"True strength is not about being invincible—it’s about having the capacity to embrace those weaker than oneself."

Gu An continued forward, and An Xin quickly followed.

As they traveled, she observed the Grand Dao Universe around them. Every star, every nebula seemed to contain profound Dao Intent, continuously deepening her comprehension through her Immortal Emperor’s Pupil.

Although they were moving slowly, the scenery around them shifted rapidly. An Xin knew this was one of her master’s abilities at work.

About half an hour later, Gu An finally halted.

An Xin stepped up beside him and looked ahead. Her beautiful eyes widened, filled with wonder.

In front of them was a vast, radiant starry sky, where countless grand immortal palaces floated above the clouds. These celestial structures rested upon the nebulae, layered one above another, forming a breathtaking scene that embodied the very essence of the Grand Dao.

Seeing the magnificent sight of the Ethereal Immortal Court, An Xin’s Immortal Emperor’s Pupil constricted slightly, as if trying to engrave the sight deep within her soul.

"Will senior brother really be cultivating in such a sacred land?"

An Xin murmured to herself, anticipation flickering across her face. She eagerly awaited the day when Tian Hao would display his unparalleled brilliance in a place like this.

Gu An’s voice carried through the silence.

"There are countless Grand Thousand Worlds, and just as many Grand Dao Universes. Even I do not know where the end of the Grand Dao lies or how many Grand Dao Universes exist. The pursuit of the Grand Dao is the most wondrous journey. To seek it is to experience longevity itself."

"Xin’er, your Immortal Emperor’s Pupil should not be limited to merely absorbing power—it should also observe the Grand Dao. The more you witness, the deeper your understanding of the Dao will become. Wushi means having no beginning, just like the boundless Grand Dao itself."

Hearing her master’s words, An Xin’s thoughts began to shift.

To pursue the Grand Dao…

Was this why her master could remain indifferent to all calamities, smiling as he overlooked the mortal world?

An Xin wanted to develop such a mindset as well, so she paid careful attention to every detail before her.

Yet even standing beside her master and looking at the same scenery, she knew she still couldn’t fathom what he truly saw.

"Master, has Tian Hao already entered?" An Xin asked.

Gu An nodded. "Yes, he is currently engaged in a duel. This will be his first battle in the Ethereal Immortal Court, and he will overcome it without trouble."

A bright smile bloomed on An Xin’s face.

Since her master said it would go smoothly, then it surely would.

The two of them stood amidst the starry expanse, gazing toward the Ethereal Immortal Court.

An Xin was completely immersed in its grand atmosphere, while Gu An quietly observed the court’s Qi Luck.

Within the Ethereal Immortal Court, there was certainly a Heaven-Opening Grand Luo Immortal, though no sign of a Wondrous Truth Grand Luo Immortal.

However, that did not mean that no Wondrous Truth Grand Luo Immortal had ever left their mark on this place.

For some reason, Gu An suddenly thought of Yongsheng’s master—Heavenly Buddha.

Where was Spirit Mountain now?

An impulse struck him—he wanted to search for Spirit Mountain.

He began to deduce the Ethereal Immortal Court’s karmic ties.

Sure enough, the Ethereal Immortal Court and Spirit Mountain were intricately connected. By tracing the karma, he would undoubtedly find a path to it.

As expected, he found it.

Spirit Mountain resided within another Grand Dao Universe. Compared to the memories left by Yongsheng, the Spirit Mountain in Gu An’s perception was even vaster.

Beneath Spirit Mountain, multiple Grand Dao Universes were being suppressed. Within Spirit Mountain itself, numerous Grand Thousand Worlds were hidden—either sealed within powerful Buddhist cultivators’ bodies or stored within certain supreme treasures.

The Bodhi Sacred Tree, where Yongsheng once cultivated, also contained countless worlds. Though these worlds were not as grand as Grand Thousand Worlds, they still nurtured their own civilizations of cultivators.
