Projection of the Heavens: I prove my immortality through slaughter.

The Mirror of Judgment hangs high, its clear, hazy light enveloping the Underworld, illuminating every cleansed spirit with perfect clarity, instantly determining merit and demerit, right and wrong. Six illusory figures, their light flowing, guide the spirits back to their rightful places according to the judgment. The entire operation of the Primordial Pure Land becomes more orderly and efficient than ever before.

However, Lin Xuan soon noticed a new problem.

As the scale of the gathering of all souls expands and the number of souls increases continuously, even with the Mirror of Judgment automatically making judgments and the six illusory figures guiding them on their own, some specific matters still require "humans" to execute and maintain them.

For example, guiding new souls who are confused and lost upon entering the underworld to the Yellow Springs; maintaining order on both sides of the Yellow Springs to prevent individual souls with strong attachments from becoming restless; "informing" those true spirits with lower intelligence who cannot understand on their own of the judgment results of the Mirror of Judgment; and even in the future, when the six realms of reincarnation are truly connected, "people" will still be needed to guide the souls of the dead and carry out punishments, etc.

As the Lord of Reincarnation and the creator of the Underworld, Lin Xuan cannot do everything himself. He needs assistants and an effective management system.

His gaze fell upon the bottom of the Yellow Springs and the more powerful souls in the six waiting areas.

These souls, in their previous lives, were either cultivators with considerable skill, descendants of gods and demons with extraordinary talent, or warriors with unwavering will. Having been cleansed by the Yellow Springs, their past lives are gone, but the essential strength of their souls and a trace of their spiritual essence remain, far surpassing ordinary souls. At this moment, they simply lie dormant or wait, like unpolished jade.

"Perhaps... we can select suitable ones from among them, grant them authority, and appoint them as Yin Gods to manage the underworld on my behalf and maintain the order of reincarnation."

The moment this thought crossed Lin Xuan's mind, he felt a sudden sense of clarity. This would not only solve the problem of manpower for managing the Underworld, but also provide these powerful souls with a better "home," transforming their power into a part of maintaining the order of reincarnation—a win-win situation.

What is the name of the deity? With a slight thought, legends about the underworld from his past life naturally surfaced.

"Therefore, Black and White Impermanence were appointed to guide and collect souls whose lifespans have ended, maintaining order in the underworld!" "Judges were appointed to assist the Mirror of Judgment, handling complex cases, recording merits and demerits, and handling documents!" "Ox-Head and Horse-Face were appointed to patrol the underworld, suppressing restlessness and guarding the entrance to hell! "Day and Night Patrol Gods were appointed to monitor the heavens, sensing the souls of the dying, and guiding the impermanent beings..."

A system of Yin spirits, based on his past life's knowledge and in line with the actual conditions of this underworld, was quickly formed in his mind.

He also had his own plans regarding the method of investiture. As the lord of the Underworld, the controller of the Reincarnation Mark, his will here contained a portion of the laws and authority. He could draw upon the power of the Underworld's origin and the Reincarnation Mark to condense divine registers and bestow them upon chosen souls. Those who received the divine registers were connected to the Underworld's destiny, able to mobilize a portion of its power, exercise corresponding authority, and become true deities of the Underworld!

No sooner said than done!

Lin Xuan's divine sense, like a vast network, instantly swept across all the more powerful souls in the Yellow Springs and the Six Paths of Reincarnation waiting area. His selection criteria were not simply based on the strength of their soul power, but rather on the "characteristics" inherent in their soul essence.

He quickly identified his target.

At the bottom of the Yellow Springs, there are two wisps of battle spirits, their soul power solidified. Though cleansed, they still faintly exude an aura of both solemnity and order. One's soul light is cold and sharp, while the other appears more composed and profound. In their previous lives, they seemed to be a perfectly coordinated pair.

"Are you willing to serve as guides and maintain order in my Netherworld?" Lin Xuan's grand Dao voice resounded deep within the two wisps of true spirit.

The two wisps of true spirit trembled slightly, conveying a sense of obedience and longing. Although they had no memory, they instinctively sensed that this was a better way out, an opportunity to integrate into this world and gain "rebirth".

"good!"

Lin Xuan pointed his fingers like a sword, drawing upon the power of the Netherworld's origin and a trace of the Reincarnation Mark, and inscribed them in mid-air! Two profound divine talismans, exuding a chilling and solemn aura and containing the authority of "guidance," "soul locking," and "order," instantly took shape, transforming into streams of light and disappearing into the two strands of true spirit!

"Buzz!"

With the divine talisman bestowed upon them, the two strands of true spirit suddenly erupted with a powerful, eerie light! Their souls rapidly solidified and expanded, transforming into two distinct figures!

On the left is a tall, thin man with a pale face, a long tongue sticking out of his mouth, wearing a tall white hat with the words "Peace Under Heaven" written on it, holding a white mourning stick, and his soul exudes a cold, soul-binding aura—this is Bai Wuchang (Xie Bi'an)!

On the right is a short, stout man with a dark face and a fierce expression. He wears a tall black hat with the words "Seeing him brings wealth" written on it and holds a black soul-locking chain. His soul exudes a heavy suppressive power—this is Black Impermanence (Fan Wujiu)!

Both were enveloped in divine light, their auras connected to the entire Netherworld, possessing a divine cultivation comparable to the early Nascent Soul stage! They respectfully bowed towards the Netherworld Palace where Lin Xuan was located: "Thank you for your grace, Master! We will certainly fulfill our duties!"

Lin Xuan nodded slightly, his gaze shifting to another wisp of soul. This true soul possessed immense spiritual power, exuding a lingering sense of righteousness and the ability to distinguish right from wrong, suggesting that he had been a powerful and decisive person in his previous life.

"I bestow upon you the divine register of a judge, the mirror to assist in judgment, and the authority to wield the documents and laws of the underworld!"

Another divine talisman, imbued with the authority of "judgment," "record," and "law," descended and merged into its soul.

In the light, a deity wearing a black gauze hat and a scarlet judge's robe, with a dignified face, holding the Book of Life and Death (illusion) in one hand and the Judge's Pen (illusion) in the other, took shape, his aura profound, and bowed to Lin Xuan.

Immediately afterwards, Lin Xuan selected two powerful battle souls with a savage aura, bestowing upon them the titles of Ox-Head and Horse-Face, and granting them the divine talismans of "Patrol" and "Suppression." The two transformed into divine bodies with the heads of bulls and horses, wielding steel forks and iron halberds, exuding a murderous aura, and guarding the vicinity of the entrance to the Hell Path.

Finally, he appointed ten spirits who were quick-witted and perceptive as day and night wandering gods, bestowing upon them the divine titles of "overseeing" and "patrolling," and ordering them to scatter throughout the underworld to monitor movements and guide the way for the impermanent.

As one by one, the Yin Gods were conferred titles and obtained divine registers, connecting with the origin of the Underworld, the entire Primordial Underworld seemed to be injected with new vitality!

Black and White Impermanence, wielding mourning staffs and soul-locking chains, began to guide the newly arrived souls into the Underworld in an orderly fashion, maintaining order in the procession. The Judge stood beside the Mirror of Judgment, carefully verifying the merits and demerits displayed in the mirror. In cases of complexity, he used his pen to draw annotations on the illusory image of the Book of Life and Death, filling in any gaps. Ox-Head and Horse-Face, like two guardian deities, patrolled back and forth at the entrance to the Underworld, their fierce gazes causing the evil souls sentenced to hell to tremble in fear, daring not to make the slightest move. The Day and Night Wanderers, transformed into streaks of ghostly light, traversed throughout the Underworld, promptly reporting the situation from various locations.

The previously somewhat "automated" underworld instantly became more "human" and "efficient" with the arrival of these spirits. A top-down management order with clearly defined responsibilities was truly established!

Lin Xuan looked at all this with great satisfaction. The existence of these Yin Gods not only relieved his management burden, but more importantly, they were part of the order of the Netherworld. Their existence and activities were constantly strengthening and stabilizing the Law of Reincarnation.

With a thought, the Reincarnation Mark glowed faintly, recording the divine information of all the Yin Gods and establishing their official status in the Underworld system.

From then on, the Primordial Pure Land not only had a core for operation (the mark of reincarnation), a standard for judgment (the mirror of judgment), and a path to destination (the prototype of the Six Paths), but also had an administrator for execution and maintenance (the Yin God system)!
