The planting and harvesting of demonic seeds follows a path of replacing the real with the false, known as "stealing the beams and pillars" and "the magpie perching in the dove's nest."
The demonic seed is the "false." Once it is implanted into the spirit and soul of a living being to make them "Heavenly Demon Kin," it begins the process of replacing the "true seed" with the "false seed," which is further subdivided into two methods.
The first is playing the long game. After planting the demonic seed, one continuously cultivates it with special secret methods so that the cultivation base of the "Heavenly Demon Kin" steadily advances, engendering transcendent power. The connection between the two sides also grows increasingly tight, with give-and-take and mutual benefits, until finally, one smoothly takes over in due course.
With this approach, the improvement in the quality of the demonic seed is practically boundless. Theoretically, even the foulest Six Desires Demonic Seed can be cultivated to the supreme realm of the Freedom Demonic Seed, but that would require god knows how many thousands or tens of thousands of years of effort. Moreover, improper handling at times causes the demonic seed's tier to regress repeatedly, which is a frequent occurrence.
The second is seeking quick results. Once implanted, it hooks into the target's essence, qi, and spirit to give birth to the demonic seed. Regardless of quality or stage, it forcibly replaces the "true seed," swallowing what is gained in a single gulp. This method is rather crude, causing permanent damage to the "Heavenly Demon Kin" and leaving them unable to make the slightest progress for the rest of their lives. Furthermore, the result of this violence—if it has already reached the transcendent tier, then so be it; but if it is only at
