[Transmigration] [Ancestral Wu] [Spy warfare] [Investiture of the Gods] [Play the pig to eat the tiger] [Ruthless and decisive] [Beast taming]
Wu Zheng transmigrates to a high-martial world and is forced by the Military Intelligence Bureau to go undercover in Nangong, an occupied territory. During the awakening ceremony, he accidentally drains half a year's supply of military-grade magic crystals from the military academy, lighting up the Nine Li Witch Pillars in his mind and awakening his Ancestral Wu bloodline. To keep his true abilities hidden, he pretends to be a low-ranking druid while secretly using Nine Li witchcraft to cultivate Gu.
Taking advantage of the rampant inflation caused by the war, he uses the Canghai Shield, which is about to plummet in value, to scoop up assets at rock-bottom prices. He buys up a vast amount of the empire's property, making money in the enemy nation while raising Gu until he becomes a god.
