The sandstorm would start after the sun has set and would subside around midnight before it would rage again at dawn.
Senja knew this and she would take this advantage from this knowledge. She would get rid of Xiao Wang Wei.
Xiao Zi wouldn't have thought that he would taste his own medicine, his son only offered his life by coming there. It wouldn't be a surprise if Xiao Wang Wei knew the layout of the fortress and how many people there, Elder Zhong must have told Xiao Zi about the situation inside the fortress and how many people who would stand on guard there. Or else, he wouldn't only take two thousand men with him to attack a fortress.
"How you will sure about that?" Qianru asked Senja in confusion, she looked at the scattered white clouds in the bright blue sky and she couldn't see a slight sign of storm. "It is bright outside…" She looked at Senja with puzzled look.
