Steadily becoming a saint, the immortal officials hired me to tend the horses

Li Ya and his disciples stayed at the Daoist Field of the Beginningless for only a month. During this month, Gu An and Li Ya traveled through mountains and waters, occasionally discussing the Dao, as if returning to their youth.

The reason Li Ya visited Gu An was to express his gratitude, but until their parting, he couldn't utter the word "thanks."

Spending a month of leisure with Li Ya made Gu An very happy. After Li Ya left, Gu An gave a lecture to all the disciples, making the Wushiji Disciples realize Li Ya's importance in An Xin's heart.

The peaceful days continued. After reaching perfection in the Xuan Qi Primordial Immortal Realm, Gu An felt that even having trillions of years of lifespan wouldn't guarantee success for his next breakthrough. Thus, he began to increase his lifespan income.

Nowadays, his dojo encompassed the entire Nine Spirit Continent, making it easy to expand the number of medicinal herbs. With the help of the Ghost Mother of Ephemera, Gu An could relax and simply enjoy the results.

A thousand years later, his annual lifespan income increased to two hundred million years.

Another million years passed.

In the Celestial Spirit Great World, similar yet different conflicts unfolded. Overall, the world was relatively peaceful, and sect disputes did not affect the common folk.

In contrast to the tranquility of the Celestial Spirit Great World, the Three Thousand Great Worlds ushered in the arrival of the Immortal Gods.

In each Great World, several Immortal Gods appeared, summoning wind and rain, bringing harmony to Heaven and Earth and all living beings. People began to believe in the Immortal Gods, strengthening the Heavenly Dao Destiny that enveloped the Great Worlds.

Under the banners of two Sons of Heaven, the Immortal Gods began to act, not only recruiting the Masters of Heaven and Earth but also guiding the masses to worship them. Meanwhile, they portrayed the opposing Son of Heaven and Immortal Gods as evil, depicting the future battle of Sons of Heaven as a catastrophic event for the Three Thousand Great Worlds, a battle between good and evil.

Gu An stayed within the Celestial Spirit Great World, watching the actions of those Immortal Gods, feeling that the Celestial Court was nothing special.

The Celestial Court was powerful enough, but its order and conduct did not match the name of the Immortal Gods.

The disparity between Immortal Gods and Mortal Spirits was vast. Mortal Spirits could not see the actions of Immortal Gods; a single word from an Immortal God would become an ancient legend that would linger in the world for thousands, even tens of thousands of years. Mortal Spirits could not guess that these myths were all conspiracies, and generational beliefs caused the Three Thousand Great Worlds to split into two, mutually hostile.

It was just past noon at the Daoist Field of the Beginningless.

Two figures descended from the sky, landing on two adjacent mountain peaks. They were the Blood Prison Great Saint and Sin.

Gu An and An Xin stood in the mountain ravine, looking up at them. The two had just flown out of the barrier established by Gu An, and the result of the battle was decided.

Sin was not a match for the Blood Prison Great Saint, but he succeeded in wounding him, surprising the Blood Prison Great Saint.

"You brat..."

The Blood Prison Great Saint widened his eyes, looking at Sin on the opposite mountain peak, unable to calm his emotions.

Though Sin still looked like a young man, he already possessed the demeanor of the Emperor of Eternal Life, with steadfast arrogance and a spirited smile, full of vigor.

"Blood Prison Great Saint, our gap has shortened again!"

Sin said loudly, his voice resonating through Heaven and Earth.

The Blood Prison Great Saint, irritated, said, "Brat, if you want to defeat me, you still need more cultivation. I wasn't serious just now."

"Is that so? I don't believe it. I think you were already anxious."

"Humph, that's my fighting style!"

The two began to argue, neither yielding.

By the small river in the ravine, Gu An and An Xin watched them bicker, smiles on their faces.

"Little Junior Brother's talent is truly frightening, it seems even greater than Tian Hao and Emperor Tianhong. Master, what is his background?"

An Xin, curious, asked. Because Sin was always taught by Gu An, others thought his rapid cultivation was reasonable. But she knew differently, as she was also tutored by Gu An and deeply understood Sin's extraordinary nature.

This boy wasn't simply growing in cultivation level; his body was already molding the Great Dao, becoming stronger continuously. An Xin sensed a terrifying cause and effect within him, a mystery even the Immortal Emperor's Eye couldn't see through.

"He comes from the Desperate Celestial Tomb, a place outside the Great Dao..."

Gu An briefly explained Sin's background. He valued An Xin highly, so since she wanted to know, he wouldn't refuse.

An Xin was his successor. Someday, she would become the Master of the Beginningless, and he could roam freely across the heavens.

After hearing this, An Xin felt a deep sympathy for Sin's past but did not show much change in expression.

Though Master didn't explain in detail Sin's identity, she did not press further.

Sin looked young, but having stayed in the Desperate Celestial Tomb for so long, he endured lonely years far beyond their imagination.

Given that Sin lived for so long, his current rapid growth was understandable. Perhaps in those endless years, Sin had been accumulating, now finally ready to erupt with power.

The conversation between the master and disciple did not reach the ears of the Blood Prison Great Saint and Sin. When the two descended, Gu An and An Xin stopped talking.

"Master, do you think he was anxious just now?" Sin approached Gu An, frowning.

Gu An patted his head and smiled, "Victory is victory, defeat is defeat. Why worry about how much effort the other put in? Continually cultivate, and one day you will win."

Sin agreed, smiling broadly, and did not dwell on the issue.

The Blood Prison Great Saint felt displeased; he didn't want to lose.

But since the words came from Gu An, he didn't dare refute and remained silently disgruntled.

"Sin, you are now a Free Immortal, capable enough in cultivation. Do you want to venture out and train for a while?" Gu An looked at Sin, smiling.

Seeing Master truly pampering Sin, perhaps even more so than herself, An Xin thought Sin's background was indeed not simple.

No matter how she looked, Sin's brows and eyes seemed somewhat similar to Master's.

Though she had such suspicions, she dared not point them out. Sin being suppressed in the Desperate Celestial Tomb for so many years indicated that Master might have encountered dreadful events in the past, making it impossible to protect his son.

Gu An, catching An Xin's inner thoughts, found them amusing.

She guessed correctly.

"Yes, can I?" Sin nodded excitedly.

Gu An looked at the Blood Prison Great Saint and said, "You accompany him to train for a millennium. No matter what he does, do not intervene. Just follow him, letting him experience and judge for himself."

"Me?"

The Blood Prison Great Saint widened his eyes, unwilling.

Seeing his reluctance, Sin immediately said, "Master, just him!"

Gritting his teeth, the Blood Prison Great Saint found the boy increasingly difficult to deal with.

"You both may go," Gu An shook his head with a smile and then turned away.

Watching him, An Xin said meaningfully, "This is not just a test for Little Junior Brother; perhaps it's also a test for you."

A test?

Hearing this, the Blood Prison Great Saint immediately felt invigorated. He loved the master's tests, knowing benefits would follow if completed.

His previous experience on the Path of the Great Dao had fruitful outcomes, not only forging numerous friendships and brotherhoods but also becoming the first Primordial Dao Emperor in the Daoist Field of the Beginningless, aside from the master.

An Xin turned and followed Gu An's footsteps.

After their figures disappeared into the forest, the Blood Prison Great Saint looked at Sin, smiling meaningfully, "Brat, in the Human World, while I won't interfere, I will report everything you do to the master."
