@sigmanesia: China’s First Emperor Built Poisonous Mercury Rivers to Live Forever China’s First Emperor Qin Shi Huang believed liquid mercury could grant him immortality and ordered deadly mercury rivers built inside his tomb. Ancient texts and modern science suggest the rivers were real, and they may have killed him instead. This is one of history’s most dangerous obsessions with eternal life. #ancienthistory #DidYouKnow #historytok #qinshihuang #mercuryrivers #chinesehistory #shaanxi #darkhistory #weirdfacts #sigmanesia
