South Demon Du Ying, a mysterious man possibly related to the medical sage Hua Tuo, had once fought fiercely with Shen Tianlong's death as their battle trigger. During the fight, Du Ying had a breakthrough, becoming a Martial Artist in the realm of True Qi, showcasing his martial arts talent.
Given that guy's obsession with martial arts, his skills in the realm of True Qi have probably deepened by now.
Ye Qiu Si pondered that after their confrontation, Du Ying had forcibly taken Ye Zi away. He then chased them to Huai Ling but failed to catch up and couldn't rescue Ye Zi, which had been a persistent regret for Ye Qiu.
"You needn't worry, by the looks of it, she's fine now," Huo Qian reassured Ye Qiu. He felt somewhat sorry for his friend since he had only recently discovered Ye Zi's whereabouts after such a long time.
Fortunately, Ye Zi was unharmed, otherwise Huo Qian's guilt would have been even greater.
