The Great Qin Sign-In System: The Ninth Prince Defies Fate

The modern young man Ying Xuan transmigrates one day and finds himself the Ninth Prince of Qin. Before he can get used to his new identity, he activates an astonishing sign-in System. By signing in at designated locations, he can receive all kinds of divine rewards.

At first, Ying Xuan quietly signs in, keeping a low profile as he builds his strength. But the Qin Empire is beset by turmoil: the Hundred Schools of Thought are secretly conspiring with the old nobility of the Six States, while the northern tribes watch hungrily from beyond the border. When Sword Saint Gai Nie betrays Qin, enraging the Ancestral Dragon and prompting a nationwide manhunt, Ying Xuan realizes the time has come. He emerges from hiding and decisively kills Gai Nie, shocking the entire court.

Afterward, Ying Xuan signs in at the Mohist Mechanist City, the Confucian Little Sage Village, the Daoist Cliff of Enlightenment, the Great Wall, and other locations, earning peerless martial arts, rare treasures, and the loyalty of numerous powerful figures. Faced with internal strife and external threats, he uses his sign-in rewards and his own intelligence to overcome one crisis after another. He builds a mighty army to repel the northern tribes, outmaneuvers the old nobility to dismantle their conspiracies, and exchanges ideas and skills with the Hundred Schools of Thought to enhance Qin's cultural influence.

The Ancestral Dragon, long worried about who would inherit the throne, is overjoyed to see how different Ying Xuan has become and decides that the empire's future is secure. Amid the court's intricate power struggles and the ever-changing fortunes of the realm, Ying Xuan steadily rises to the pinnacle of power, reshaping Qin's destiny and becoming a legendary emperor.
