My Mandarin, the Strongest Law in Another World

Traveling through another world, I became a mute waste. Until I couldn't bear it anymore and shouted at the God of Law: "What are you looking at?!" The next second, Dharma God replied uncontrollably: "Look at you!" The whole network... Ah no, the whole continent exploded! From then on, my Mandarin became the most powerful forbidden spell in the world. I teach classes, teach pinyin, and teach grammar. When the enemy troops were approaching and thousands of mages were chanting forbidden spells, I cleared my throat and picked up the trumpet: "Everyone has it! Recite - "Thoughts on a Quiet Night"!" At that moment, the world soared.
