Starting from Breaking Off the Engagement in Gaoyang, We Will Build the Peak of the Tang Dynasty!

[Avatar history + Tang Dynasty + Pretend to be a pig and eat a tiger + Easy daily life] Standing in front of you now is: the guardian of the Tang Dynasty, the closest comrade-in-arms of Emperor Taizong, the good brother of Prince Li Chengqian, the richest man in the world during the Zhenguan period, the gravedigger of the noble family, the first of the twenty-four heroes of Lingyan Pavilion, the founder of the poetry world of the Tang Dynasty, the founder of modern science... But before that, Chen Yu, who had just traveled through time, was a little depressed. The good news was that his Chen family from Yimen in Jiangzhou was involved in the Xuanwumen rebellion. The bad news was that Li Jiancheng's family... What's even more outrageous was that Li Shimin wanted to marry Gao Yang to him. Haha, Gao Yang... Wouldn't even marry a dog!
