Zhanguo Qiannian

I, Ji Qing, crossed into the Gaowu version of the Spring and Autumn Period and the Warring States Period. You have a sword, I can't die! You have the magic of the world, I can't die! You have a nearly-godlike move, I still can't die! An ordinary person who can't die no matter what, how will I fare in this war-torn world of rigorous battles?
