On the Day of the College Entrance Examination, I Spent 3 Yuan to Instantly Kill the Gods and Demons.

My name is Xu Jin, and I had insomnia the night before the college entrance examination. I thought I was hallucinating, and a 3-yuan skill system appeared in front of me. [Skill: Little Flame (3 yuan)] [Skill: Small Water Drop (4 Yuan)] [Skill: Little Breeze (3 yuan)] I bought a small flame for 3 yuan. I thought it was some rubbish skill until I encountered an attack from gods and demons... I raised my hand to make a small flame, and all the gods and demons collapsed to the ground in fear, muttering to themselves: "This, is this taboo?!" "Brothers, run, run!" —— I looked at the little flame I bought for 3 yuan and nodded with satisfaction. "Xu hope, let's go home for dinner." … My name is Xu hope, and I have an older brother named Xu Jin. But one day, I found something was wrong with me. The flames and water droplets in my brother's hands can actually make gods and demons kneel down and call their master. Later I discovered that he possessed forbidden power that even gods and demons could not touch. But every time after dealing with the gods and demons, he always looked distressed. "Another 3 yuan wasted." "Looks like I'll have to save some money in the future."
