Signing In to Biyou Palace's Core Forbidden Area, Obtain "Origin Fragment of Formation Dao"

Ten days had passed since his return from Zixiao Palace, and the gathering storm clouds above Jin'ao Island grew ever more apparent. Duobao Daoist had convened meetings with the heads of various halls daily, the number of disciples patrolling the perimeter of Biyou Palace had multiplied several times over, and even the spiritual light of the island's protective formation shone a third brighter than usual. Lin Xuan (Xuanyuanzi) knew well that the external situation was precarious and that the sect was not a monolithic entity. Only by rapidly improving his strength and solidifying his foundation could he stand firm amidst the coming upheaval.

This night, the moonlight was like water, and the Milky Way stretched across the sky. Lin Xuan sat in meditation, meticulously reviewing the insights gained from listening to the Dao in Zixiao Palace. He felt his Dao foundation grow more profound, and his perception of the laws of heaven and earth had become much sharper. Suddenly, a subtle shift in his thoughts brought forth a long-unheard System prompt in his sea of consciousness, carrying a solemnity and depth unusual for it:

[Ding! Detected Host in a special environment: Biyou Palace core area (within the radiation range of the Shangqing Xuanyuan Formation Eye).]

[Detected Host's formation comprehension level has reached a critical point (Zixiao Palace Dao Charm enlightenment + Nuwa's Creation Pure Qi nourishment).]

[Detected external environmental pressure index increase, Host's demand for "Formation Dao" has drastically increased.]

[Hidden conditions met: Heavenly timing (peak moonlight), geographical advantage (formation eye radiation), human harmony (comprehension breakthrough). Triggering a special sign-in mission in a core forbidden area!]

[Special Sign-in Mission: At midnight, when the moonlight directly shines upon the "Shangqing Xuanyuan Formation Eye," complete a deep formation comprehension sign-in.]

[Mission Description: This formation eye is one of the core hubs of the Myriad Immortals Formation system laid out by Sovereign of the Heavens on Jin'ao Island, containing a trace of the Jie Sect's Formation Dao origin charm. Successful sign-in may yield high-level rewards related to the essence of formations.]

[Warning: The formation eye's energy is immense. Maintain your focus during comprehension and proceed within your capabilities.]

Lin Xuan's spirits lifted, recognizing a rare opportunity. He quietly rose and, following the System's subtle guidance, avoided the patrolling disciples and headed towards the forbidden area in the deep rear of Biyou Palace, a place normally heavily guarded. The deeper he went, the more concentrated and pure the surrounding spiritual energy became. Countless fine runes flowed through the void, forming layers upon layers of profound and intricate concealment and protection formations. Had he not carried a trace of the Azure Pine Sword Seal's Dao charm, been recognized by Biyou Palace's formations, and had the System secretly harmonized his vital energy, he would have long ago triggered the restrictions.

He stopped before a circular altar surrounded by nine towering jade pillars. The altar was ancient and unadorned, but its center featured a recess shaped like a Taiji symbol, or perhaps an unopened lotus. It was precisely midnight, and a bright moon had risen to its zenith. Its cold, clear moonlight poured down like a waterfall, precisely into the recess.

Buzz--!

The altar vibrated gently, and billions of minuscule, dust-like runes appeared on its surface, flowing like a river of stars. In the central recess, the moonlight condensed, transforming into a mass of chaotic light. Within it, it seemed as if the creation and destruction of the four elements—earth, water, fire, and wind—were taking place, or perhaps the fundamental principles of heaven and earth were interwoven. A vast, ancient, and powerful Dao charm, pointing directly to the origin of formations, permeated the air.

"Now is the moment!" Lin Xuan sat cross-legged at the designated spot before the altar, held his breath, and sank his entire mind into comprehending the mass of chaotic light, simultaneously issuing a command to the System: "Sign in!"

[Sign-in command confirmed! Connecting to the "Shangqing Xuanyuan Formation Eye" Dao Charm... Analyzing formation origin rule fragments...]

[Warning: High concentration of law information flow detected! Activating buffering protocol!]

[Sign-in successful! Congratulations to the Host for completing a deep formation comprehension sign-in in the Biyou Palace core forbidden area!]

[Epic-grade reward obtained: Origin Fragment of Formation Dao (a wisp)!]

Following the System's prompt, Lin Xuan felt an indescribable torrent of information, containing the most fundamental and complex principles of formations in the universe, surge into his sea of consciousness like a breached dam! This was not a specific formation diagram or incantation, but something more essential—a fundamental understanding of how "energy nodes" should be optimally distributed, how "law runes" could harness the power of heaven and earth, how "spacetime curvature" could affect formation effects, and how "cycles of generation and destruction" maintained formation balance... a grasp of the underlying rules!

In an instant, Lin Xuan's vision seemed to encompass the very beginning of creation, the separation of the pure and impure, the union of yin and yang, and the natural formation of various "formations" during the genesis of all things! The orbits of the stars were formations, the flow of rivers were formations, the cycle of seasons were formations, and even the breathing of living beings and the circulation of their blood all secretly adhered to the principles of formations! Formations were not created from nothing by human effort, but were the discovery, imitation, and sublimation of the inherent "order" and "momentum" of the natural world!

All the formation knowledge he had previously acquired, whether it was the basic Spirit Gathering Formation, the Maze Formation, or the complex "Minor Nine-Bend Yellow River Formation," now became incredibly clear under the illumination of this "Origin Fragment"! Many points that he had previously understood the "what" but not the "why" were suddenly illuminated! He could even "see" several subtle nodes in the simplified diagram of the "Myriad Immortals Formation" that Wuyun Xian was currently deducing, where the energy flow could be further optimized!

This "Origin Fragment of Formation Dao" was like a universal key, opening the deepest door to the grand hall of the Dao of Formations for him! Although it was merely a crack, a glimpse, its significance far surpassed learning hundreds or even thousands of specific formations!

[Origin Fragment of Formation Dao (a wisp): A minuscule manifestation of the Great Dao laws of innate formations.]

[Effects:]

1.  **Greatly enhanced formation comprehension:** A qualitative leap in the ability to understand, learn, and create formations, making it easier to grasp their essence.
2.  **Increased formation affinity:** More adept at setting up and controlling formations, achieving greater resonance with the formations of heaven and earth.
3.  **Formation-breaking intuition:** When facing unknown formations, the ability to more quickly identify their energy nodes and operational patterns, improving the efficiency of breaking them.
4.  **Foundation for optimization and innovation:** Provides the fundamental theoretical support for the Host to optimize and innovate formation systems based on scientific thinking.

After a long while, Lin Xuan slowly emerged from that profound state of comprehension, his eyes shining with a divine light, as if he could see through the countless energy trajectories in the void. With a thought, he casually sketched a few simple runes in front of him with his own magical power. What previously required careful adjustment to set up a small warning formation was now executed with effortless fluidity. The runes naturally integrated, and the formation was instantly complete, its effect more than thirty percent stronger than before!

"Is this... the power of touching the origin?" Lin Xuan was shocked and delighted. With this gain, his confidence in facing future changes had increased once more! Especially for the upcoming "Scientific Version of the Myriad Immortals Formation" plan, this "Origin Fragment of Formation Dao" was undoubtedly a crucial core asset!

He bowed respectfully to the altar and quietly departed. The forbidden area of Biyou Palace under the moonlight returned to silence, with only the formation eye continuing to absorb the moonlight, as if nothing had happened.

However, a seed, deeply understanding the essence of formations, had been planted in Lin Xuan's heart. It only awaited the arrival of wind and rain to take root and sprout, growing into a towering tree that could shelter a region.
