Travel Through Time and Become a Cat to Cultivate Immortality

The war between monsters, humans, and demons never ends. The immortals regard all people in the world as pawns and can play with them at will. Reborn as a cat, with an ever-growing technology tree system, it stepped into this vast prehistoric world. The fairy mecha is ever-changing and can defend against all enemies in the world. The demon clan used all the power of the clan to destroy the world, and the supreme demon-killing cannon blasted them to death. The forbidden area is invaded by evil spirits, and the space atomic bomb destroys it. When the dynasty was extremely corrupt and the world became a purgatory, the Immortal and Demon Maker created an army for me to change the dynasty. When immortals stop me from cultivating immortality, then there will be no immortals in this world.
