Archaeologist Zi Lin Ye accidentally traveled through the Daxia Dynasty. At that time, there were many loopholes in border defense. He combined his knowledge of construction and institutions related to ancient tombs and ancient buildings, and cooperated with border officers in on-site inspections to help improve defense facilities and add security agencies, which slightly made up for some shortcomings in border defense. On weekdays, he also uses related skills to participate in city defense repairs, collecting and sorting scattered ancient books, and sorting out and preserving ancient cultural context. He only used his own knowledge to do his best, and on the basis of the court's overall coordination and the military and civilians jointly guarding the border, he jointly alleviated the border difficulties and helped Daxia gradually stabilize and develop.
