Eternal Path: from Primitive to Supreme

The male protagonist is a former top archaeologist on Earth. He accidentally discovers an ancient multiverse portal. He deciphers the murals and learns that alien civilization will fully invade the earth in 10 years. The only way to salvation is to randomly select 1,000 earthlings through the portal and travel to an alien plane in the multiverse. After cultivating to the strongest in the plane, they can open the world passage and return to save the world. World; the male protagonist becomes the chosen one and travels to a different plane parallel to the earth. The system only grants three major abilities: unlimited lifespan, freedom to change body shape/appearance, and final positioning of the original earth coordinates. There are no tasks, no attributes, no shopping malls, and no skill blessings. The entire process relies on the male protagonist's own knowledge, will, and wisdom to promote the development of the plane and self-cultivation. Core obsession: The concern of his parents in the original world and the life and death agreement with the heroine supported him to transcend eternity, go through iterations of civilization, and finally become the supreme king of the plane.
