Primordial Era: At the beginning, the Desolate Heavenly Emperor invited me to drink beast milk, and

Qin Yuan pondered for a long time, and realized that neither of these two paths was easy to take.

Improving the Yin-Yang Formation is no easy task. Even with his extensive knowledge of both realms, his understanding of formations is far from reaching that level.

As for alchemy, starting from scratch to study alchemy would require an unknown amount of time and effort.

Suddenly, Qin Yuan's lips curled into a slight smile.

He's getting stuck on one thing; there's no need to do everything himself.

Since you can't solve it yourself, you can always ask for help from higher authorities.

Thinking of this, Qin Yuan immediately activated his internal magic power and used his supernatural abilities to return to the primordial world.

He took a deep breath and began to activate the Yin-Yang Formation.

In an instant, waves rippled outwards, and mysterious array patterns appeared and disappeared in the void.

The barrier of light rippled like water, and Qin Yuan's formation resonated with it.

Before long, ripples appeared in the void, and a figure stepped out from them.

The Tongtian Sect Leader stood with his hands behind his back, his blue robe fluttering in the wind.

He looked at the formation Qin Yuan had set up, his expression showing a hint of surprise.

Logically speaking, without reaching the realm of refining emptiness and uniting with the Dao, it is impossible to comprehend this.

But this young man in front of me not only mastered the key to the formation, but could also activate it at will.

Such talent is truly astonishing.

Qin Yuan dispelled the formation and respectfully bowed to the Tongtian Sect Leader.

The spiritual energy in the valley surged, replenishing all the spiritual energy consumed when the formation was activated.

The Master of Heaven looked at his disciple and became increasingly satisfied.

Now it seems that my judgment was indeed correct.

"You've certainly impressed me."

"Although the Yin-Yang Formation is the foundation of the Ten Thousand Immortals Formation, it is already remarkable that you have mastered it at your level."

Qin Yuan bowed and said, "This disciple is humbled; it was merely a coincidence."

Since the beginning of time, the Tongtian Sect Leader has seen countless geniuses.

Some Dao Child Realm cultivators can walk on air, some Bigu Realm cultivators can subdue demon kings, and some Golden Core Realm cultivators can open up cave heavens.

But Qin Yuan is the first person to comprehend the Yin-Yang Formation while still in the Qi Refining Realm.

It should be noted that although the Yin-Yang Formation is only one of the basic formations of the Myriad Immortals Formation, the mysteries it contains are extremely profound.

Even many celestial beings in the Jie Sect, despite exhausting their entire lives, could not fully comprehend its mysteries.

He originally thought that someone with Qin Yuan's talent was extremely rare, even in the vast universe.

But now it seems that my initial assessment was too conservative.

As originally expected, if Qin Yuan could comprehend the Myriad Immortals Formation within a hundred years and reach the Refining Void and Harmonizing Dao realm, he would already be a rare genius.

If we were to bestow upon him a few treasures at that time, it would be enough for him to roam freely throughout the prehistoric world.

But the current situation was something he never expected.

How old is he? He has already mastered the essence of the Yin-Yang Formation.

Such talent is extremely rare, not only in the Jie Sect, but also in the entire prehistoric world.

The Master of the Heavenly Sect fell into deep thought.

Although the Ten Thousand Immortals Formation is a treasure of the Jie Sect, wouldn't it be too simple for Qin Yuan?

When the idea first came to him, even he found it incredible.

But the facts speak for themselves: this thirteen-year-old boy has already demonstrated an comprehension far beyond that of ordinary people.

If he were to cultivate in a step-by-step manner, it might actually limit his development.

But the problem now is that he has already agreed to let Qin Yuan travel to the prehistoric world.

As a sage, a word once spoken cannot be taken back.

Moreover, he always values ​​his promises the most, and there is really no reason for him to take it back.

The path of spiritual practice should not be limited to sitting in meditation.

Simply engaging in arduous practice, even if one manages to attain enlightenment by chance, will hardly lead to great achievements.

How can a true strongman be forged without experiencing trials and tribulations?

This principle is perfectly clear to Tongtian.

The valley is shrouded in mist and clouds, and a spiritual energy flows through it.

Tongtian looked at the seemingly ordinary young man before him and secretly made his own plans.

Sending Qin Yuan out to gain experience so hastily would be too hasty.

However, with proper guidance, it could very well be an opportunity.

In fact, Qin Yuan had no intention of actually traveling around.

He hasn't even been born into the perfect world yet, so why would he be in a hurry to enter it?

This is simply an excuse for his occasional disappearances.

Qin Yuan composed himself, stepped forward, and bowed respectfully.

He knew this was the perfect time. Since the Tongtian Sect Leader valued him so much, he might as well voice his doubts.

"Grandmaster, I have recently come across a problem while studying the Yin-Yang Formation, but I am not sure if I should talk about it."

"But it doesn't matter."

As a sage, Tongtian never adopted a superior attitude towards his disciples, especially when discussing the Dao.

Qin Yuan slowly revealed his confusion.

"This disciple has discovered that the consumption of magical power is extremely high each time the Yin-Yang Formation is used. Even setting up a small formation requires nearly 30% of the magical power."

"This disciple humbly requests your guidance: is there any way to make slight modifications to reduce consumption?"

After listening, Tongtian seemed to be deep in thought.

He did indeed create the Yin-Yang Formation, and he was intimately familiar with its mysteries.

In his view, the problem was not difficult to solve.

Simply adjust the positions of a few key points in the array to change the direction of spiritual energy flow.

With a wave of his hand, a ray of spiritual light flashed in the void.

With a light tap of his finger, Tongtian sent the spiritual light instantly into Qin Yuan's brow.

In an instant, a vast amount of knowledge about formations flooded into Qin Yuan's mind.

It includes not only the complete modification scheme of the Yin-Yang Array, but also many related derivative changes.

The sudden influx of information left Qin Yuan momentarily dazed.

He originally thought that this problem would require the Tongtian Sect Leader to think carefully, but he didn't expect to get the answer in an instant.

Moreover, this knowledge far exceeded his expectations.

The spiritual energy in the valley rippled slightly, as if it too was awestruck by this moment of instruction.

Qin Yuan tried hard to digest the information in his mind and gradually understood its mysteries.

It turns out that by simply making slight adjustments to a few key nodes in the formation, the spiritual energy can flow more smoothly and its consumption can be greatly reduced.

This change seems simple, but if Tongtian hadn't personally guided him, he probably wouldn't have been able to come up with it even if he spent his entire life trying.

"By the way, since you can grasp the wonders of formations so quickly, I should also grant you a chance."

Before he finished speaking, Tongtian waved his sleeve, and a streak of azure sword light appeared in the void.

The sword light was condensed and did not dissipate, exuding a faint pressure, yet giving people an indescribable sense of intimacy.

The sword light hovered in mid-air for a moment, then suddenly transformed into a streak of light, shooting straight towards Qin Yuan's brow.

Qin Yuan felt a cool sensation, and then he felt something new between his eyebrows.

With a light touch, a faint blue sword mark appeared.

This sword mark is not a physical entity, but a mysterious imprint containing a wisp of sword intent personally refined by Tongtian.

In critical moments, it is enough to protect him.

Qin Yuan never expected that he would receive such a generous reward for simply asking about formations.

To obtain a protective item personally crafted by a sage is an immense opportunity for the entire Jie Sect.

He immediately knelt down and respectfully kowtowed.

"Thank you for bestowing this treasure upon me, Master. I will always remember your great kindness."
