The black death

Achoo! What is wrong today? I do not know! Oh, this reminds me of death, but scarier, the black death! In the medieval age, millions of people died from disease, it first started in Hubei,China alone. Then traders and merchants carried the dead to Italy, then it killed 1,000,000,000 people in Europe! Did this end? No! After spreading to other places, people stopped living in castles. Phew! That was a tragedy!
