Rebirth from Scratch

He was unexpectedly reborn as the legitimate son of a scholarly family. He was literate at the age of three, talented at the age of five, and famous at the age of seven. However, at the age of eleven, his family was wiped out, and the protagonist died tragically on the spot. He accidentally activated the golden finger bloodline with him, so he climbed up from the blood of the wiped out family. From then on, he embarked on the road of pretending to be a pig and eating a tiger, leaping over the ranks to fight back, and then step by step to find out the truth and start revenge.
