Magic? This Is Called an Instruction

Zheng Chen traveled through a world of swords and magic. What should I do if I don't know magic? Hey, there is a system! Wait a minute, what system is this? What about the mission? What about the mall? Where is my reward? Why is there just a bunch of code? Grand Magister: "What kind of magic is this?" Zheng Chen: "This is the law of the world. I call him instructions. Do you understand? Baby." This is the story of a coder from a different world.
