How Did I Become an Ancestor After Signing in at the Imperial Tomb for Ten Thousand Years?

Because Chu Ping, the ninth prince of Chu, accidentally broke a plate on the table on the birthday of Emperor Chu, he was deprived of his royal status by an imperial edict from Emperor Chu and demoted to a commoner to guard the imperial mausoleum. Just when Chu Ping thought it was a foregone conclusion that he would waste time in the imperial mausoleum until his death, he actually awakened the "sign-in system"! As long as you keep signing in, you will continue to receive rewards. Sign in at the Imperial Tomb on the first day and get the "Chaos Body". Sign in at the Imperial Mausoleum the next day and get the "Breaking Eyes of Illusion". Sign in at the imperial mausoleum on the third day and receive the "Four Swords of Killing Immortals". … Thousands of years later, demons were everywhere, and hostile forces also rose up to attack Chu. The capital of Chu was about to fall. With a gentle palm from Chu Ping, all the enemies were reduced to ashes. The people of Chu all shouted: "Long live the ancestor".
