Sign-In in the Womb: I Lead My Family to Invincibility

[System + no CP + invincible protagonist + power fantasy + family-building] Di Jun transmigrated into a fantasy world. In his previous life, he worked himself to the bone; this time, he wanted to live like a lazy fish. But his family was on the brink of ruin, about to be wiped out and forced to eat their own children. Di Jun was desperate, but there was nothing he could do: he was still a fetus. At the critical moment, he awakened a sign-in System, and signing in granted him the cultivation of a True Immortal, making him invincible. “Sign in and receive a top-grade spirit vein.” “Sign in and receive a secret realm.” “Receive a divine beast...” Many years later. Di family's gatekeeper: I used to be an ordinary person. Now I'm a True Immortal. Di family's dog: I used to be an ordinary dog. Now I'm a handsome guy (in human form). Reincarnated female emperor: I reincarnated to rule the fantasy world, but somehow became a disciple of the Di family... (This is great.) Di Jun leads his family to the top of the world. Anyone who bullies us will be killed; anyone who insults us will have their entire clan exterminated...
