Sui Dynasty Guards: the Hand Slipped and Selected the CP Mode at the Beginning

Yang Chuyuan traveled through time and became the personal bodyguard of Emperor Yang of Sui Dynasty, and was tied to a wicked system. The system asked him to match up Li Shimin and Princess Nanyang. He is a die-hard fan of Li Jiancheng and is forced to help his enemy pick up girls. Quit? The penalty is unknown and the probability of triggering is 100%. Done? Three-legged Cat Kung Fu can be upgraded to a level. He threatened Li Shimin to participate in the school martial arts competition. The next day, the whole palace was rumored that he and the second young master Li were in a relationship. Later, he used the Jianghu vest "Chu Xun" to leave a secret code in the late Sui Dynasty, Doraemon. After each action, one was drawn. People in the world thought it was a mysterious organization. Yang Guang ordered a thorough investigation. The Turkic Khan pretended to understand. The hero of Wagang said that this mythical beast was too fat. After Li Shimin ascended the throne, he asked him what the secret code was. He said it was called Doraemon, a cat-shaped robot that could take out anything from its pockets and help a useless elementary school student solve all kinds of troubles. Then he followed Xuanzang to obtain Buddhist scriptures. Helping two people fall in love is more tiring than fighting.
