I'm Setting up a Stall in the Last Days

In the near future, the "Mist of God Ruins" suddenly descended on the earth, humans mutated into monsters after being infected, and the survivors awakened "sequence talents". There are "relics of the old gods" hidden in the fog, which can tamper with reality by devouring human beliefs. The mastermind behind the scenes controls global power in order to compete for the "godhead". The protagonist appears to be a weakling, but actually relies on the law of props and cause and effect to deceive others; one person stands alone against a wave of millions of mutated beasts, and the props all explode into fireworks, awakening the God-killing sequence; the heroine is voluntarily sealed to protect the protagonist, and the protagonist uses a "memory eraser" to make her forget herself, and finally they meet again on the street as strangers.
