I’m Only Eight, So What’s with This Old-Age Comeback System?

[Future old-age System + comeback + face-slapping] After transmigrating into a high-martial dynasty as a disgraced prince, he gets the Old-Age Comeback System seventy-two years too early. [At eighty, you lie in the dilapidated prince's residence in Anzhou, coughing up blood. Nobody knows. Nobody cares.] Gu Yun'an glances at the miserable state shown on the screen, then at his own eight-year-old body. Looks like this System arrived a little early. [You've decided to make a comeback. Take the first step and complete one cycle of drawing qi into your body to receive a god-tier constitution, the Chaos Divine Body!] [Some junior who is only thirty dares to show you no respect. Rebuke the youngster to receive a god-tier cultivation method, the Myriad Paths Furnace Scripture!] [Eighty is the perfect age to strive! Seize the throne and become the ruler of all geniuses to receive a god-tier weapon, the Xuanyuan Divine Sword!] From then on, Gu Yun'an becomes the one and only Human Emperor of the Nine Provinces and Eight Wastes!
