The Age of Mist: I Use the Xueba System to Defeat the Apocalypse

On the first day of school, the end comes!​​ The fog swallowed Huayang No. 2 Middle School, zombies broke through the door, former teachers and classmates turned into bloodthirsty monsters, and the campus became a purgatory! When the students were awakening to control fire, giant strength, and sword control, and fought their way through the tide of corpses, Xia Yanxing, the number one god of study in the school, became the only "negative force"—— Superpower? Doesn't exist! "Could it be that the top student's doomsday scenario is to serve as a cheerleader for people with superpowers?" Seeing the approaching "Old Corpse Wang", Xia Yanxing complained crazily. Bite! The academic system is activated! Please host use knowledge to analyze...] "You're going to test me even after I've already failed? You're cheating the system!" [If the analysis is successful, any super power can be obtained 100% for free! "... I told you earlier! It turns out that this is the realization of knowledge at the end of the world?!" At the same time, a "Monster Hotel" with a strange painting style opened its door to him: The lucky raccoon rolled around and begged to be fucked, the barking dog held a basin in its mouth and begged to be taken care of, and the third prince Nezha banged the table and roared: "Boss Xia! Here comes a plate of fried dragon eggs with tomatoes!" "Boss, if guests give the hotel a five-star rating, they can randomly select magical powers, and they will make a lot of money!" As a result, the doomsday style of painting completely collapsed——​​ Others relied on their superpowers to pierce through the zombie tide, but Xia Yanxing relied on solving equations to make the Corpse King shut down on the spot! Others relied on tough monsters to level up, but Xia Yanxing deceived the gods to give the hotel good reviews, and used prostitutes to reach the full level for free! When the final BOSS arrived and the strong man was in despair, Xia Yanxing pushed up his gold-rimmed glasses (which did not exist): "Don't panic, Schrödinger's cat said, we are now in a superposition state of winning and winning being more beautiful..." Academic system + doomsday survival + fairy and monster shelter + hilarious High-energy reversal every week, knowledge is the strongest power!
