Why the hell did I read this, just WHY?? I have been crying over this for the whole night now and thought of sharing my sorrow. This is the worst possible thing that could happen. I was scrolling through Reddit and found a post in r/todayilearned. The post linked to this Wikipedia page. According to the page, Ying Zheng (El Sei in Kingdom Manga) died from willingly taking poison. In that era, mercury was assumed to be something that could prolong life, heal people and maintain good health. Qin’s alchemist and court physicians created mercury pills for Qin Shi Huang (Ying Zhang’s name after Unification of China) believing it to be the elixir of immortality and ingesting these pills led to Ying Zheng’s death.
I thought that he would have died an epic death in some great battle (like the battle he fought against Riboku with the people of Qin). This is unbelievable, I don’t even know what to say anymore.
