Transmigrated as the Crown Prince's Mate - Chapter 9: Role Reversal...

18 years have passed since I was born as Allen, the eldest son of an earl in this world, while still retaining my memories of the present world. This world is peaceful and a stable society. The only extraordinary thing is that I was reincarnated into a world that is lenient on the existence of concubines. I selected a silver-haired maid as a sex slave and second wife candidate from among 10 candidates after a strict fellatio practical exam. I then lived an erotic life at home and at school as an attendant, but my reincarnated life is so fulfilling that I'm worried it will explode, as my busty childhood friend, a noble girl who was unsuccessful, ran for the third wife candidate, and my stepmother, who was my virgin partner, was sold off.

From humble beginnings, he ascended, overcoming every obstacle and living life on his own terms—until death took its toll. Yet destiny had a different design. Reborn into a world of greater splendor and majesty, he is granted a fresh start and boundless opportunities to rise again. This time, his journey begins from an entirely new vantage point, as he is reincarnated as the son of the most powerful woman in the universe. Follow his path of ambition and indulgence as he forges a new legacy and leaves his mark on an even grander stage.

Callius von Jervain.

And I have to carve out that route somehow.

Because I’ve become Callius von Jervain in the game.

In the rebirth, in order to prevent the tragedy of the previous life from happening, Bai Yu decided to rush to the [Tower of God] at any cost, and face everything together with his sister!

However, Bai Yu, who was bound by the system, mutated his bloodline, and transformed into a black-scaled python seems to be developing on a completely different path from his previous life…
