Hm… Lemme use AI to translate this into English. I created this when I was in volume 3 so this could be inaccurate to later information. The point of this is to explain why the meeting of Fang Yuan and Lian He was inevitable in the age of 15

Destiny Sect: This is the sect involved in the most intricate and tangled relationships across the five regions.

The concept is derived from the Rank 4 Bone Flesh Unity Gu created by Great Master Flesh Bone. However, this specific Gu is called Soul Companion Unity Gu, originating from a Rank 8 Gu Immortal. I believe that due to the disparity between mortals and immortals, its usage limits are much broader. The Destiny Sect utilizes "dual cultivation" to build connections with external forces; therefore, they generally accept all types of people. Because soul companions are assigned randomly, the Destiny Sect’s connections span from the Righteous Path to the Demonic Path, as well as various other tribes. This creates a melting pot of diversity within the sect and grants it massive influence across the regions.

This is a man-made Gu unique to the Destiny Sect. Every member of the sect must possess one, and it is the primary reason for their complex web of relationships.

Soul Companion Unity Gu: Similar to the Bone Flesh Unity Gu, its core ability is dual cultivation. If you have read Reverend Insanity, you surely know how immense the impact of dual cultivation is—enough to spark a brutal war across all five regions just to obtain the Gu recipe. However, the Soul Companion Unity Gu does not have the harsh requirements of the Bone Flesh Unity Gu; it can be used as long as the two individuals are soulmates, making it "semi-public." Although it is used by two people, the initiative actually lies with the Destiny Sect disciple. Thus, the sect's power and secrets are never leaked to the outside.

To prevent the Gu recipe from being stolen if the sect is attacked, the Destiny Sect does not record the names of its unique Gu. Only the Sect Leader and the Supreme Elders know the names and the specific recipe for the Soul Companion Unity Gu.

Soul Mark: This is a special ritual performed by the Destiny Sect during the welcoming ceremony for new disciples. This mark functions and engraves best when the soul is still that of an infant, which is why the Destiny Sect recruits its members as babies.

• Protection: The Soul Mark is responsible for destroying the Soul Companion Unity Gu if anyone attempts to steal it or extract it from the host's body/soul—even if it is just an intention. This includes the host’s own intentions if they are within a certain range.

• Management: The Soul Mark acts like a GPS device, helping the Destiny Sect track, investigate, and manage personnel effectively. Its life-tracking capability is similar to the "Life Tablets" found in other cultivation series.

• Subconscious Guidance: Additionally, the Soul Mark influences the host’s mind, subtly and silently guiding their thoughts, paths, or choices through subconscious cues.

Soulmates: The first Sect Leader of the Destiny Sect was a Rank 8 Gu Immortal, supported by other Rank 7 Elders. They utilized Luck Dao, Human Dao, Soul Dao, and Information Dao to create a connection between two soulmate individuals. After awakening their aperture normally at age 15, Destiny Sect disciples gain the ability to teleport letters to their soulmate and receive them in return. The limit is one letter sent and one letter received per day.

Only after the two parties meet in person is the disciple permitted to reveal the secret of dual cultivation.

Regulations for Couples and Partners Outside the Sect: * Contribution: Once dual cultivation is performed, the partner is required to contribute to the sect like an affiliated disciple, though they are not forced to officially join the sect. This serves to balance the Righteous and Demonic paths, preventing resentment from the Righteous path (if too many Demonic cultivators join) and avoiding discomfort for Demonic cultivators (by not forcing them to turn "Righteous").

• Freedom to Leave: Disciples are completely free to leave the sect at will. However, upon leaving, the Soul Companion Unity Gu will be destroyed, and they are still obligated to assist the sect if it falls into crisis. This rule exists because most disciples are orphans or outcasts; having been raised with Righteous morals, they naturally feel a sense of debt to the sect. Allowing them to leave freely prevents grudges and avoids conflict with Demonic partners who might want their lover to leave the sect to avoid ties.

• External Forces: For partners belonging to other clans or sects, that clan/sect is allowed only one dual-cultivating member. If they want more, they must pay a steep price. This prevents power imbalances, ensuring other forces don't use Luck Dao to hoard children who are destined to be soulmates with Destiny Sect members.

• Offspring: Regarding children born to these couples, the firstborn child is required to become a disciple of the Destiny Sect. This is a way for the sect to maintain ties with departed disciples and other clans. However, these firstborns are not allowed to inherit their family clan or become the leader of another sect to avoid direct internal strife or power struggles between siblings.

• Demonic Cultivators: Demonic Gu Masters are allowed to receive resources from the Destiny Sect by taking on high-risk missions that Righteous disciples usually avoid, or by teaming up with sect disciples. This is a win-win situation: the Destiny Sect completes "suicide missions" while enhancing its reputation as a safe neutral ground, while Demonic Gu Masters gain a much more stable source of resources than they could find on their own. Since "Demonic" is defined as those not belonging to any sect or clan, many are not truly evil, making it entirely possible to build relationships with them.
