I Just Transmigrated into the Fated Villain, and the System Bound Itself to the Nation

Yun Shen from a parallel world transmigrates. And he transmigrates into the fated villain of a third-rate web novel. Fortunately, the villain he transmigrated into has already made it through the entire story. Unfortunately, his cultivation has been completely crippled, leaving him unable to fight. The heroines he once wronged start showing up one after another. The fated goddess he humiliated by breaking off their engagement. The holy land's saintess, whom he forced into dual cultivation. The peerless empress who was betrayed by him. The childhood sweetheart he swindled out of everything. The disciple he sold out. “What a mess!” Watching the heroines show up one by one to settle old scores, Yun Shen lets out a helpless cry. At this critical moment, Yun Shen suddenly awakens the Myriad Realms Dao Ancestor System. He can choose a faction to spread the Dao to and gain the cultivation of everyone in that faction. Yun Shen promptly chooses his homeland. The System binds itself to the Dragon Kingdom. From then on, a Dao Ancestor rises, and the entire nation of the Dragon Kingdom cultivates immortality!
