At the same time Xu Nian, the main character, was heading to the Tianhen Continent with the seven beauties, the Undying Devouring Sky Beast had already crossed the Death Sea along with the Tianbao Pavilion Master and others.
During this journey, which lasted over ten days, Xu Nian's cultivation quietly broke through to the Immortal Realm.
The core within his body underwent a tremendous transformation.
The core of the Undying Devouring Sky Beast was like its own world.
Originally, it covered an area about a thousand miles in radius.
Now that Xu Nian's cultivation has broken through, the entire land expanded to reach an area of five thousand miles.
Besides this, the changes in the core emitted powerful energy, feeding back to enhance itself.
Making Xu Nian's physical form further strengthened, it now entirely rivals top-grade spiritual artifacts.
Even the hardness of special parts such as wings and claws was approaching the level of an Immortal Artifact.
