I Am Slaying Chaos in the Dragon Kingdom

[Soldiers and veterans × high school students who are afraid of death] As a defender of the country, I took five days off, but in fact I lived in the city for five full years. I thought I would just get away with it for the rest of my life, but when I went to the market to buy groceries, I got a call from my old comrade. "You feel uncomfortable if you don't get scolded for a day, don't you? Do you know how busy I am now?" "Lao Yang, there's a little monster running out here, please help check it. Don't you happen to have a few newcomers over there? Let them practice their skills." "Specific location." "Don't you know how to do your own calculations? Why are you asking me? Besides, don't you know how to divine?" After returning home, Granny Lan said that a boy named Lin Dong wanted to learn painting from me. When I saw the person, I was stunned for a long time - good guy, Lao Ye's apprentice. --- My name is Lin Dong. My previous painting teacher got a promotion and a salary increase and left. My grandfather found a new teacher for me in the village, named Jieyang. The first time we met, he asked me if I wanted to save the world and be a hero. Oh. Of course, whatever he says is what he says, can I still resist? What if he doesn't teach me anymore. Then he raised his hand in front of me. Two qi, one black and one white, circle around the fingertips. I stared at the two qi for a long time, and there was only one thought in my mind - this teacher didn't seem to be a charlatan. I took it easy for a while and finally made a decision. Okay, then I'll do whatever it takes, and when I've cultivated to the point where I'm invincible, I can then save the world.
