When Qin Shou wakes up, he finds himself in another world, inhabiting the body of a fifteen-year-old boy with the same name. Before he can celebrate having transmigrated into a new life, his cruel second uncle sells him to the palace, where he becomes a powerless eunuch-in-training. After an extremely crude "operation," the original owner dies in agony from an infection, and Qin Shou, a modern man, takes over his broken body.
On the verge of death, the legendary "Strongest Bloodline System" suddenly awakens. Qin Shou is overjoyed, thinking he's about to defy fate, crush evil servants, kick the tyrant, and reach the pinnacle of life, until he sees the full details of his bloodline ability.
[Source Blood of Creation]: Can infinitely strengthen one's direct descendants. The stronger the offspring, the greater the strength they return to him.
Qin Shou looks down at his empty lower body and falls into a long silence.
Heavens, are you messing with me?
Forced to accept reality, Qin Shou can only scrape by in the imperial palace under the identity of "Eunuch Qin." By chance, a pregnant lynx in his care licks his bloodied wound. The cub she gives birth to is somehow connected to his thoughts and grants him enhanced physical strength.
His cold fate cracks open, just a little.
Blood as the bond, beasts as offspring. If human bloodlines are out of reach, then he'll create an unprecedented bloodline of all spirits!
It's all interlocking, it's okay, and the beginning is not too templated.
