During the Spring and Autumn Warring States period, China had no shortage of powerful princely states, but the Qin State was unique and successfully unified the six countries, which aroused people's curiosity: What "black technology" helped Qin Shi Huang achieve this feat? This article will explore some of the "black technology" items that emerged at that time and provided strong support for Qin Shi Huang's unified six countries.
First of all, we want to mention Qin Jian. In the history of human warfare, the era of cold weapons is the dominant stage. Different soldiers use different weapons, such as archers using crossbows, and melee soldiers may prefer to use long weapons such as spears. However, as the "king of a hundred soldiers", the sword has excellent lethality, especially in the hands of soldiers who specialize in swordsmanship. The sword of the Qin Kingdom is longer than that of the other six countries, and its forging technology is also more advanced, making the Qin sword more lethal on the battlefield than its peers.
Another important technique is the Qin crossbow. The crossbow had greater lethality than the bow and was originally invented to counter the cavalry threat. The lethality and range of the Qin crossbow surpass the crossbow arrows of other countries, and the State of Qin has specially developed supporting arrows to make the combat effectiveness of the Qin crossbow better.
Qin Shi Huang also presided over the development of the "railway", although it can only be glimpsed from the restoration drawings today. During the Spring and Autumn Warring States period, the logistical supply of the army was crucial, so Qin Shi Huang ordered people to build tracks similar to modern railways from wood, on which special carriages could be transported, greatly shortening the supply transportation time.
In addition, Qin Shi Huang also presided over the construction of the "Qin Straight Road" and the "Qin Great Wall", which complemented the aforementioned "black technology" items and jointly helped Qin Shi Huang smoothly unify the six countries.
