As the first unified multi-ethnic state in Chinese history, the Qin Dynasty also opened a new page for the sons and daughters of China. The self-proclaimed "emperor" of Qin Shi Huang also reflects his unique historical status, and Qin Shi Huang has also left many unsolved mysteries.
For example, Qin Shi Huang has a variety of the mystery of his life, he also sent the Taoist Xu Fu to find the elixir of immortality, as well as the mystery of the underground palace of Qin Shi Huang's mausoleum, etc., and the legend that Qin Shi Huang ordered the casting of the "Ding Qin Sword" has also attracted widespread attention.
According to relevant records, Qin Shi Huang forged a total of two "Dingqin Swords", one hidden in the Afang Palace and one hidden in the Riguantai, as for their true features, due to their age, posterity has no way of knowing.
In the 1970s and 1980s, part of the Terracotta Warriors and Horses of the Mausoleum of the First Emperor of Qin was unearthed, which once caused a huge sensation in the archaeological community. Among them, there is a magical bronze sword, which can withstand hundreds of kilograms of pressure and can still be immediately restored to its original state, completely refreshing people's cognition.
Although this is not really the "Dingqin Sword", but as one of many funerary items, scientists still try to study it in more depth. Because according to the level of scientific and technological development at that time, it was almost impossible for the Craftsmen of the Qin State at that time to produce memory metals.
However, with the help of advanced science and technology, scientists performed X-rays on the entire bronze sword and quickly obtained accurate composition information.
Scientists were surprised to find that there was a layer of chrome salt oxide screen on the surface of the bronze sword, which was able to protect the sword body from corrosion for more than 2,000 years. In addition, the sword body is also added to the appropriate amount of tin during the casting process, which improves the protection for the toughness of the entire sword.
This has far exceeded people's cognition, because the chrome salt oxide screen is only widely used in modern industry, and it is almost impossible for the ancients to master the relevant technology, as well as the amount of tin, the ancients must have had a unique wisdom to master it so precisely.
Although at present we still have not found the real "Dingqin Sword", but from the bronze swords unearthed from the mausoleum of Qin Shi Huang, each one has an advanced level of craftsmanship, perhaps it is a superb level of weapon manufacturing, the Qin State can unify the whole country in the chaotic world and create brilliant achievements.
Perhaps the real "Dingqin Sword" has disappeared into the dust of history, but every bronze sword that exists is a "Dingqin Sword", because with them, there is an invincible Qin army.
