Qin Wang Jian, also known as the first sword and pulley sword, is more than four feet long and extremely sharp, cutting iron like mud, and is now in the Museum of the Mausoleum of the First Qin Dynasty. It is said that when this sword was discovered, it had been crushed by a terracotta warrior weighing 100 kilograms for many years, and its body had been bent. But after this sword was dug out, the blade naturally bounced straight. Only the toughness of this sword has surprised the onlookers at that time.
It is impossible to prove who made this Qin Wang Jian. The earliest historical records about swords can be traced back to the Qin Dynasty. At that time, there was a very powerful general in the State of Qin named Bai Qi, who made great contributions to Zhao Haoqi of the State of Qin. However, in his later years, he was framed and put to death for offending the response at that time. The sword used in Leitian's suicide was this Qin Wang Jian, which was only called "Cosmic Peak" at that time, and was later renamed Qin Wang Jian in the hands of Qin Shihuang.
There is another saying about Qin. It is said that during the Qin Shihuang period, the State of Chu had a sword named Tai 'ajian, because it could please the greedy monarch of the State of Jin. In order to get this sword, the State of Jin spared no expense to make a fortune, but it was defeated. Later, the reputation of this sword spread to the ears of Qin Shihuang, who also wanted to have this sword, so he destroyed the State of Chu in one fell swoop. Later, this magical Tai 'an sword came into the hands of Qin Shihuang, became the exclusive sword of Qin Shihuang, and was renamed Qin Wangjian.
