Lin Xuan, a Blue Star college student, traveled through time and became Han Canglan, the general of the Northern Zhou Dynasty. He had just achieved the immortal feat of sealing the wolf to Xu, but he saw through Emperor Zhou Jingyan's murderous intention of "killing the donkey" and defied the order in public and killed the eunuch who passed the order, completely breaking with the imperial power of the Great Zhou Dynasty. His confidence comes from the god-level summoning system bound after time travel - he can summon absolutely loyal heavy armored cavalry by spending silver. With a military salary of 8,000 taels, he can hold 800 steel heavy cavalry in his hand, becoming a sharp blade that overturns the capital. On the way to Beijing alone, Zhou Jingyan resorted to a beauty trap and lured him into the trap with a tender and secret message from the original owner Bai Yueguang, now Xiao Shufei, but Lin Xuan saw through it at a glance and burned it.
