I, the Mythical Roc, Became the Companion Beast of the Empress

In the fantasy world, if a monk wants to gain powerful power, he must have a companion spirit beast of his own. My name is Jiang Peng, and I was reincarnated into a mixed-haired Peng bird. Fortunately, the awakening sign-in system allows me to become stronger as long as I sign in. My contractor is an ambitious little princess who wants to rule the world and ascend to the fairy world every day. ... My name is Mu Yunhuang, and I am a reincarnated person. I once established an immortal fairy court in the fairy world, and was revered as the empress. However, I was betrayed by others. I plan to practice hard in this life, make up for all regrets, and avenge my great revenge. But soon, I felt that there was something wrong with my companion spirit beast. I only slept and ate every day, and I was not active in cultivation. I had no choice but to work hard on my own, but as time passed, I suddenly found that my half-living spirit beast was a bit scary. It is actually the golden-winged roc from mythology and legend!
