What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
In 221 BC, after ending hundreds of years of war in the Eastern Zhou Dynasty, the Qin King Yingzheng annexed the Six Kingdoms, unified the world, China entered the feudal era, after Qin Shi Huang unified China, he promulgated a series of measures to stabilize the country, the car with the same track book, and then attacked the Xiongnu in the north to build the Great Wall, and drove Baiyue to build the Spirit Canal in the south, initially establishing the prototype of today's China. That Qin was able to unify the world, in addition to the efforts of the Qin monarchs and the stimulation of the military merit system, the advanced manufacturing and production level of the Qin State also played a major role. With the excavation of the Terracotta Warriors, people gradually saw something that should not have appeared in the past two thousand years, which can be called black technology equipment.
First: Qin bronze sword
The bronze sword was a weapon commonly used by all countries in that era, but the difference was that the bronze sword of the Qin State unearthed in the Terracotta Army was still very sharp and tough, and after more than two thousand years, it did not have too much rust, and the power of use was not reduced, which was admired by the superb forging process of the Qin people two thousand years ago. In addition, scientists were surprised to find that there was a layer of chromium salt oxide layer on the excavated Qin bronze sword after testing it, which may be the reason why the Qin sword was not rust for two thousand years, but what is even more confusing is that the technology was not mastered by the Germans until the 1930s, and how the Qin State two thousand years ago understood and applied this technology.
Second: Qin crossbow
The inconceivable thing about the Qin crossbow is not its design and power, but that each Qin crossbow seems to be customized, with the same regulatory requirements, that is to say, the same parts of different crossbow machines are completely universal, that is, what we call standardized production today, to know that this concept was first proposed by the Americans after the Revolutionary War. Two thousand years ago, under the background of relying entirely on manual manufacturing of crossbow machines, it is really amazing how Qin crossbows can achieve such a small error and standard production.
Third: Qin Chi Dao
When the Qin army was in the conquest, in order to ensure the movement of subsequent supplies and reinforcements, it would often build a smooth road from the capital to the front line, lay specially treated wooden planks on the compacted ground, these wooden planks were not afraid of fire, insect bites and rot, so that the Qin army's carriage could move forward quickly, with the Qin army's conquest footsteps gradually connecting most parts of the country, these two thousand years of roads are undoubtedly one of the magic weapons of the Qin army's victory, solving the problem of the Qin army's supply and troop mobilization, and also becoming a shortcut for the Qin army to attack everywhere.
In this way, the Qin army more than two thousand years ago, with the support of sophisticated equipment, inspired by the military merit system, and under the leadership of successive kings, it seemed inevitable that the Qin army would conquer the world from the Six Kingdoms of Hangu Guandong. But in fact, behind this is the efforts of the Qin people for hundreds of years, it is the inevitable unity of the hearts of the people in the world, and those who win the hearts and minds of the people win the world, otherwise no matter how sophisticated the weapons and the brave army, they will not be able to stop the hearts of the people of the world from turning their backs and attacking them en masse.
