I, son of the northern border, land god

Chen Beixuan traveled to another world and became the son of a king with a different surname, bearing the name of a dude.
Because of the system, he needs to go out to practice and sign in for three consecutive years before he can get the novice gift package.
At the beginning, he was inherited by the sword god Li Chungang and became a land god.
The emperor granted the marriage, Chen Beixuan didn't want to be the son-in-law who was like a hostage, so he led troops and horses across the rivers and lakes.
