Upgrade Gift Package

Zhen Kaikai, who became the Tianjiao Prince of the Tang Dynasty after traveling through time, did not gain game skills, nor did he bring any mysterious items. His body and soul did not mutate, and he did not know any summoning skills. It's just that... He got a newbie gift package and an upgrade gift package sent by an unknown master. Since then, there has been one less unknown white-collar worker on the earth, and there has been an arrogant and domineering genius king Tang Jin on the Douxian Continent who is practicing hard! Tang Jin murmured to himself: "Upgrade, I promised you that the upgrade gift package would be guaranteed to be at the top level..."—————————————————— Tang Jin thought to himself: Feeling aggrieved? Pretending to be cowardly? Frustrated? Bear the humiliation and bear the burden? Impossible! Damn it, if you dare to mess with me, I will destroy your whole family!
