The First Sword of Spring and Autumn

The so-called chivalrous person is one who must follow his words, be sure to bear fruit in his deeds, be true to his own promises, not love his body, go through the hardships of a scholar, and recite his righteousness thousands of miles away. The killer travels back in time to the Spring and Autumn Period, but the Spring and Autumn Period is not like the past. In this Spring and Autumn Period, warriors can create mountains and rivers, and sages can summon wind and rain. I saw that the rivers and lakes were stormy, demons were rampant everywhere, and the iron horse and gold could not stop the suffering of the people. Only knights can control the country and eliminate demons. The killer thought: In this life, I will be a hero.
