I Transmigrate as the Demon Lord, and the Reborn Empress Contracts Me?

Su Li transmigrated and discovered that he had arrived in a world of demons, where he had become a young Fire Demon, a juvenile Shendu. There were other young demons here too: the adorable little Water Demon Basha, the chubby Mountain Demon Bogan, the Thunder Demon Zhong Su... The demon world was like a prison, and escape was impossible. Fortunately, he awakened the strongest Demon Parasite System and happened to be summoned by a campus belle! From then on, he arrived on Blue Star, and the world changed beyond recognition. My name is Luo Ziwei, known as the aloof campus belle of the slums. But what people don't know is that I am the reincarnation of the Ziwei Emperor. In my previous life, my contracted beasts held me back and wasted my talent and potential. Now that I've been reincarnated, I will never make a contract with a spirit beast! I planned to pick any old spirit beast to help with my cultivation, but I never expected that this creature, which looked just like a bipedal lizard, would bring me countless surprises. Speed that transcends time, explosions with limitless energy, medical skills that cure every illness, strength enough to move mountains... No matter how many years pass, I will always remember the day I first summoned it, and the words spoken by that petite figure descending from the sky: “Are you my little maid, then?”
