The Empress's God-Tier Beast

Rogue, reincarnated as a Demon Beast egg, is contracted by reborn human expert Serena Lynn. He awakens the Divine Beast Evolution System, able to absorb all things to strengthen himself. In her past life, Serena Lynn contracted an ordinary Demon Beast, failing to reach the highest realm. Reborn, she abandons her old partner, choosing a new Demon Beast egg, mistakenly believing it mediocre, lamenting her cultivation path.
