Jin Cheng

Are you here to make fun of steel training in the Spring and Autumn Period? Even if you can make it, you can beat a steel knife within a month or two. It took more than 1,000 years from bronze to steel. Really poisonous

When King Wu conquered Zhou, the transportation line for the army going east was in the southern Shanxi and western Henan areas. Most of the local minor princes were allies, or at least good-faith and neutral. After the establishment of the Zhou Dynasty, a large number of small countries were granted confederation here in return for their merit. Duke Zhou was running Luoyi, and the route from Haojing to Chengzhou was still the same, right under their noses, and it was too unsafe. Taking advantage of the fact that the Tang rebellion was suppressed, Tang Shuyu, the younger brother of King Zhou Cheng, was consecrated to Tang Dynasty (later changed to Jin), with the purpose of adding sand to the situation and controlling the local situation. So it's definitely not because of that jokey sycamore leaf.

When writing a historical novel, even though it is a novel, it should also be consistent with history. Otherwise, why not just write about a different world? It is better to express yourself and write whatever you want.
