My Ex Kicked Me Out in the Apocalypse, So I Summoned the Earth God

Bad news: At the graduation party, my childhood sweetheart, now suddenly rich, dumped me! Good news: On the eve of the catastrophe, I awakened a System. Bad news: It's a Journey to the West System that only lets me draw one card a day. Good news: The cards are permanent and can be upgraded and combined. Bad news: Each new card seems to foreshadow an unknown disaster to come. On day one, I drew [Earth God's Burrowing Technique]. I was wondering what use it could possibly be when the teaching building collapsed. Everyone watched as I dug the campus belle out of the ground. My ex and her new rich-boyfriend (stunned): "What kind of lame superpower is that?!" On day two, I drew [Howling Celestial Dog]. Before I could even complain, I was surrounded by a pack of mutated dogs. I silently summoned the phantom of a divine hound, and the whole pack ran off with their tails between their legs. The aloof campus belle (eyes wide with shock): "You... summoned a god?" On day three, I drew [Banana Leaf Fan]. Before I could even figure out what it was for, a spiderweb blocked the highway. The rich kid was still trying to burn through it when I gave the fan a single wave, blowing him, the flames, and the spiderweb away together. Everyone: "..." On day N, I drew [Dragon King]? A flood broke out, and the campus belle was swept into the river, crying for help... [Thousand-Mile Eye]? [Jade Purifying Bottle]? [Somersault Cloud]? [Sea-Calming Divine Needle]? Permanent use? Help! I just want to keep a low profile and grow stronger, but the System keeps forcing me to become the world's most powerful person with the best connections!
