I Backed Li Jiancheng, and Li Shimin Panicked and Married Off His Daughter Overnight

Gu Chen transmigrates to the end of the Sui Dynasty. Through a twist of fate, he becomes a disciple of the divine Daoist Li Chunfeng and catches the eye of the great general Li Jing, who takes him on as a prized student. But this also draws him into the conflict between Crown Prince Li Jiancheng and Prince of Qin Li Shimin.

Determined to win Gu Chen over, Li Jiancheng even asks to become his student. In a panic, Li Shimin marries off his own daughter that very night, all to bring Gu Chen into his camp.

Thus begins Gu Chen's journey through the Tang Dynasty.

During the Wude era, he pacifies Xiao Xian, defeats Liu Heita and the Turks, and turns the tide at Xuanwu Gate, ultimately becoming a legendary god of war.

During the Zhenguan era, he defeats Luo Yi and the Turks, brings Tuyuhun to heel, earns the title Duke of Qin, marries Princess Changle Li Lizhi, and is honored in the Lingyan Pavilion for his lasting achievements.

During the Yonghui era, he outmaneuvers Zhangsun Wuji and deposes Wu Zetian, assisting Emperor Gaozong in ushering in the Yonghui era of good governance. Serving three reigns and rising to the highest office, he ultimately becomes the emperor's foremost teacher.

Looking back, half his life has already passed. Yet when he turns around, his beloved wife is still only in her early thirties.

With a beauty in his arms and power in his hands, Gu Chen is the strongest carbon-based life-form of the seventh century...
