Building a Century-Old Clan, Starting in Sui-Tang

Wu Xin, whose soul had crossed into the world of a historical novel, was informed by the System bound to him that he had to establish a clan that would survive for five hundred years. The problem was, he had not fused with the original host's memories, so he could only feel his way forward.

Starting out as a beggar, he ingratiated himself with Li Yuan, offering advice and helping him overthrow the Sui dynasty and ascend the throne, ushering in the Tang dynasty.

After the Xuanwu Gate Incident, just as he felt his mission was finally on a stable path, he received a mysterious letter: “My lord, after losing contact with you for more than a decade, we have finally found you. You're incredible! With your own strength, you've become a confidant of the new emperor. Once we arrive, we'll join forces to take the new emperor hostage, and our great cause will be accomplished in an instant.”

Wu Xin was dumbfounded. Who exactly was the original host? Had the System assigned him the wrong mission?
