Qin Shi Huang unified the six kingdoms with these three treasures, and there was one that was too advanced, and Europe only had it after 2000
Speaking of the Qin Dynasty, the first thing that comes to mind is Qin Shi Huang, who established a unified empire in Chinese history, but the Qin State was not a powerful country before. Later, after the martingale transformation method, it slowly became stronger. Then, in addition to going through the Shang martingale transformation method, the Qin state can become stronger. Are there other reasons? The three treasures unearthed by the Terracotta Warriors and Horses of Qin Shi Huang prove that Qin Shi Huang also relied on these three treasures to unify the Six Kingdoms.
The first is the bronze sword that everyone knows. A batch of bronze swords unearthed in the Terracotta Warriors and Horses of Qin Shi Huang averaged 80 centimeters in length. Later, experts found that the excavated bronze sword had a dense structure, a smooth and smooth body, a delicate blade grinding, and no interlacing of textures. Although these bronze swords have been buried underground for more than two thousand years, they are still bright and sharp when they are unearthed. Later, experts discovered that the bronze fitness surface had a layer of ten microns thick chromium salt compound. This discovery was a sensation around the world at the time. Because this process of chromium salt oxidation is a process that has only appeared in recent times. The earliest discovery in Germany was also in 1937, but what is shocking is that as early as the early Warring States period of the Eastern Zhou Dynasty, China Mobile had mastered this advanced technology.
The second is the crossbow. The Qin crossbow is made of mulberry wood, and the wooden arm of the Qin crossbow is generally 60 to 75 cm long and four to five cm wide. Because the entire bow stem is entangled with dense leather, this not only enhances the structural strength of the bow stem, but also the toughness of the leather is excellent and the elasticity is strong. This sophisticated design greatly improves the reliability of the projection, the error rate is greatly reduced, and the vibration during firing is reduced, which greatly improves the shooting hit rate. This crossbow not only shoots farther, is more lethal, and has a higher hit rate. The range unearthed in the Terracotta Warriors can reach three hundred meters, and similar weapons were only designed in Europe at the end of the nineteenth century, that is, the Chinese Qin crossbow was more than two thousand years earlier than Europe.
The third piece is a bronze arrow. Terracotta warriors unearthed a large number of three-sided shaped arrows. Experts have found that this arrow can not only easily pierce the armor of the enemy, but also the manufacturing process is also very complicated. Because its three arc surfaces are basically exactly the same, the margin of error is between 0.01 centimeters. This manufacturing process is simply breathtaking in the Qin Kingdom more than 2,000 years ago.
