Before Wen Xingzhi evacuated, he only did one thing: he rescued Wen's mother from Xie Yun's grasp and killed Xie Yun.
Xie Yun died contentedly, with no regrets. He had initially thought that by burning the granaries in the city, Wen Xingzhi could at most last seven days since a single granary was not enough to supply the needs of nearly three hundred thousand soldiers. When the granaries were gone, Wen Xingzhi would be defending a city devoid of food supplies. He was certain reinforcements wouldn't come quickly, so after seven days, Wen Xingzhi would have to evacuate rather than starve. But he did not anticipate Ling Hua's cunning siege method, which remarkably broke Youzhou City with such ease.
So, in his dying moments, Xie Yun accomplished what he clenched his teeth to achieve, looking at Wen Xingzhi's dark expression, he peacefully closed his eyes.
