I Transmigrated into a Gender-Swapped Female-Centric Novel, and I’m Going on a Rampage!

Wu Feng accidentally transmigrates to a fantasy world. As he sorts through his memories, everything seems strangely familiar. When a System calling itself the Simp System appears in his mind, he finally realizes the truth: he's transmigrated into the body of the male lead in a ridiculous female-oriented gender-swap novel! He commands an army of 600,000 loyal troops guarding the border, and his cultivation has reached the strongest Human Realm pinnacle in the entire nation. Yet after a letter from his “beloved,” who betrayed him to marry the emperor, promising him a chance to marry her if he crippled his own cultivation and returned to the capital alone, he actually cripples his cultivation and prepares to head back by himself? And now a Simp System has appeared, demanding that he go to the capital and grovel at the heroine's feet? Wu Feng says that's unacceptable! I command 600,000 troops, and some rebel dares sit on the throne and stage a coup? Simp System? Whoever wants to simp can do it themselves. If you've got a problem, come fight me!
