The power of the Blood Demon Seed's growth is absorbed and assimilated by the Demon Lord. When it matures, it condenses into a "Blood Fruit" within the body.
Through a special ritual, the Blood Fruit is refined into the body, possibly stimulating further self-metamorphosis and growth of the bloodline. The better the quality of the Blood Fruit, and the larger the quantity, the easier it is to stimulate success. Given the bloodline level of the Snake Mother, it would require at least 45 Level 8 Blood Fruits for a small metamorphosis. This has already cost it half a lifetime's efforts.
