After Three Years of Sign-In, I Turned the Prince's Estate Into a Forbidden Land of Gods and Demons

[The rating just came out, but it’ll rise later. Sign-in + invincibility + faction building + no goody-two-shoes heroics + decisive and ruthless] After transmigrating to a fantasy world, Long Youyou becomes the frail, sickly third son of the Prince of Zhenbei. Don’t want to cultivate? No problem, the System signs in automatically! After signing in for three years from the start, all the servants in the prince’s estate have changed beyond recognition: The old woman sweeping the floor is a peerless sword god who can cleave open the gates of heaven with a single strike! The woman chopping vegetables in the kitchen is a ninth-rank pill saint who has slaughtered countless people! Even the limping old man who feeds the horses is the former King of Assassins, once feared by all seven kingdoms! On his wedding day, the foolish emperor sends a hundred thousand Imperial Guards to surround the estate and wipe out the entire Long family? Long Youyou sighs and tosses away the melon seed shells in his hand. “I meant to treat you like ordinary people, but you insist on courting death.” At his command, the ground of the estate erupts! Three thousand Snow Dragon Cavalry shatter the void, while a hundred thousand Grandmaster-level death warriors draw their blades! That night, blood ran through Xuanwu City like a river, and the red wedding silk became a crimson carpet. The Prince of Zhenbei returns from the front lines, sees the ground strewn with saint-level corpses, and trembles. “Son, is this what you meant by a tiny bit of family wealth?”
