Fantasy: I Just Took a Nap, Why Am I Invincible?

In the great battle of the world, all gods compete. Countless geniuses have gone through life and death, staining the sky with blood, just to get that chance to become immortals. Lu Changge traveled through time and became the son of a fallen god, but was accidentally bound to the "Big Dream Eternal System". While others have been practicing hard for thousands of years, he just throws down his head and goes to sleep! "The young master of the Ancient Sacred Mountain came out of seclusion and developed the world-suppressing magical power?" "Sorry, I just rode the ancestor of the ancient sacred mountain as a horse in my dream." "The Son of Destiny arrived with the Wutian soldiers, threatening to destroy the Nine Heavens?" "Don't disturb my sleep. The so-called imperial weapons are just defective products refined in my dream." Everyone laughs at him as a lazy, useless person. Until that day, darkness and turmoil swept across the heavens, the Immortal King shed blood, all realms collapsed, and hundreds of millions of creatures fell into the abyss of despair. Lu Changge, who was sleeping, was unhappy because his dream was disturbed. With just one look, the eternal starry sky shattered, and the arrogant dark ancestor was wiped out in ashes! For a moment, the whole world was dead silent! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
