The refining process was hard and unbearable for a child like Xiu'er. In fact, even adults would wail and scream like the progenitor did a while ago.
The process felt like someone was skinning you alive and your organs were ripping apart. The feeling was excruciatingly painful that you might just wish to die. In this stage, the relief of death was better.
However, Xiu'er had no plan on giving up. He was determined to prevail in the end. After all, only him could do this. Besides, he was doing this for the sole purpose of his mother. He wanted to save her, as soon as possible. He wanted to see his mother alive.
"Ahhhh!!!" Xiu'er kept on screaming and screaming. His screams were quite miserable, but you could hear and feel the hardness of his voice.
