School Belle, Don't Get Me Wrong, What I Sell Is Very Serious.

[Time Travel + Universal Job Change + System Cheating + Face Slapping Counterattack] I traveled to the doomsday world a thousand years later—— Humanity huddles in a steel fortress, and "professionals" are the last line of defense. During the job transfer ceremony, I awakened the SSS-level [Holy Envoy], But was ridiculed by the entire Internet: "It is recognized as the most useless profession! Without holy relics, it is garbage!" The principal looked on coldly, and the genius fireball attacked secretly. The whole class was waiting for me to drop out in embarrassment... [Ding! The urban exchange system is activated! "Today's special offer: ①Liuwei Dihuang Pills (8 points) ②Electric mosquito swatter (with Thunder Tribulation instruction manual)" Looking at the hand-made "nuclear bomb-level firecrackers" and "causal fruit knife", I grinned in the ruins: "Who said that holy relics must be archaeological?

The Lord of Steel City couldn't afford to kneel down: "Please use this Shennong cauldron... No, use the rice cooker to make elixirs!"
