Wei Yu

Wei Yu was a male Chinese assassin living in during the Qin Dynasty. He was responsible for the death of Emperor Shi Huangdi, who was supposedly a Templar.  In 211 BCE a large meteor is said to have fallen in Dongjun in the lower reaches of the Yellow River. On it an unknown person inscribed the words The emperor died during one of his tours of Eastern China, on September 10, 210 BCE (Julian Calendar) at the palace in Shaqiu prefecture (沙丘平台), about two months away by road from the capital Xianyang.Reportedly, he died of swallowing mercury (poison) pills, made by his court scientists and doctors, which contained too much mercury. Ironically, these pills were meant to make Qin Shi Huang immortal. Wei Yu was said to had re-modified the pills. It was also said, he was resposible for the death of Emperor Shi Huangdi's son (Ying Huhai)
