Reborn Skeleton: Accidentally Summoned by the Cool School Beauty

(No system + upgrade + summon flow) Lu Ziyu, who had just been reborn as a low-level undead skeleton, had no time to adapt to the gray-white skeletal body, and was transported to a parallel world by a mysterious force. Unexpectedly, he also became the spirit of Qing Leng's school beauty. From then on, his life and destiny were bound to the school beauty. Fortunately, I got the talent of Origin Devouring. What about the weakest bonded spirit? As long as it is swallowed, it can continue to evolve until it reaches the unfathomable realm of gods! ..... My name is Liu Yiyi, a senior high school student in Yanbeicheng. On the contract day, I contracted a low-level undead skeleton. Fortunately, thanks to the blessing of the ancestral star, the undead clan's undead summoning technique can continuously summon the undead army. The contract owner and the contract spirit share life, and I have to protect the contract spirit. However. My bond seems to be different from others. He devours any material containing energy and transforms it into the material needed for his own evolution. Rise from the bottom of life! Swallow the iron-haired wild boar, swallow the iron-blooded demon tree, swallow the slime, swallow the two-headed chimera, swallow the frost demon wolf, swallow the legendary ancient dragon, and swallow the evil god peeking at the ancestral star. When all races invaded, Lu Ziyu had already ignited the divine fire and became an immortal god!
