Yan's foreign relatives, give Da Yan a little Xuanwu Gate shock

The ancient empire is in chaos, and snow-covered jackals are lurking on the border.
How did my great Da Yan become like this?
He traveled to Terra Dayan 50 years ahead of the main storyline and became Wei Yanwu's cousin, who was about to be enfeoffed in Longmen.
Should I follow him and use the poems and songs in my mind to become a great writer, or should I whip Terra and the foreign relatives who abuse their power?
Yuan Congqian thought about it, and in order to maintain his status as a relative of the emperor, he decided to help Lao Wei’s younger brother announce his Xuanwu Gate plan first!
