"Husband, be careful." Su Yunjin didn't know much about King Chu's martial arts. She hadn't seen him make a move, but she had once witnessed his Qinggong. In the blink of an eye, King Chu could vanish before her eyes, so his martial arts were probably not lacking.
Moreover, the people around King Chu were all quite capable. Even if King Chu's martial arts weren't as strong as those around him, they were certainly stronger than Gu Ya's martial arts.
Su Yunjin knew Gu Ya's archery was impressive. She had seen him hit every target without fail. But no matter how good Gu Ya's archery was, he knew no martial arts. King Chu was strong in martial arts; how could Gu Ya possibly be a match for him? Afraid that Gu Ya would suffer and get hurt, Su Yunjin's heart was in her throat!
