The old man shook his smoking pipe and inhaled deeply.
"You called it an infection. Here, we called it a plague," declared the old man, as if to answer Gu Juexi's question earlier.
"The plague took a lot of lives, including the husband and wife of the Ye family and their youngest son Ye Xuan. The brother, Ye Shu, and the sister, Ye Di survived," said the old man with a sob.
"All his life, Brother Ye practiced medicine to help the people, but in the end, he died of the plague. Anyway, humans are very selfish by nature."
As the old man was telling the story, Ye Yuwei's hands curled into a fist.
"The first one to fall sick in the Ye family was Ye Xuan. The couple wanted to send Ye Shu and Ye Di away but no one was willing to take them in. Ye An was worried that the two kids might be infected by their brother, so he sent Ye Xuan to the isolation center. There were only a bunch of sick people there in the isolation center."
