The Warring States period was arguably the era of the fiercest warfare in ancient China, yet it is now hard to find works set in that time. There are barely any novels or games tagged with the period, and that saddens me. So I studied all kinds of documents and books in depth, and traveled around the internet visiting various museums. In the end, I began writing this Records of the Warring States, based on Records of the Grand Historian. I hope to give readers vivid characters, profound historical events, rich details, and a smoothly unfolding plot, much like Romance of the Three Kingdoms. If you want to understand the Warring States period, I think you should look at it through the state of Zhao. Zhao fought the Xiongnu and Linhu in the north, maintained relations with Han and Wei in the south, held off Qin and Loufan in the west, and kept an eye on Yan and Qi in the east. Of the Seven Warring States, Zhao bordered five of them.
