An Immortal King Ancestor Guides My Path, and Now I’m Invincible!

[Semi-invincible + no System + decisive and ruthless + no harem, though there will be a few close female friends. A near-perfect fanfic, but it starts earlier in the timeline. Don’t read if that’s not your thing! Don’t read if that’s not your thing!] Good news: I transmigrated! Bad news: This world has foreign realms, the Immortal Realm, the Nine Heavens and Ten Earths, and even the Boundary Sea! Yun Zefeng, who transmigrated here, became a member of an imperial clan of the human race in the Immortal Realm. With an Immortal King ancestor protecting him, an innate sacred-body Dao embryo and double pupils, plus four auspicious signs accompanying him from birth, he remained invincible even without the so-called golden finger. He will fight through a golden age, forge an invincible heart along the ancient starry road, and carve his name into the Imperial City, letting it shine through the ages! When the dark creatures on the other side of the Boundary Sea try to cross it and unleash a dark calamity upon all the heavens, will he shout, “How could cultivators like us fear a fight!” or hide in the broken worlds at the edge of the wilderness, struggling to survive?
