The reason they were here was to settle some affairs. As far as this Wu Yating goes, she was just incidentally here as well.
But regardless, this was Wu Yungang's niece, so she was also someone he knew. Thus, he definitely could not let anything happen to her.
He felt like he had a better understanding of the situation now. If he had not appeared today, Wu Yating definitely would have been taken away.
From what he saw in past, this Wu Yating was going to die. Maybe she would live one or two days. But, once she dies, Wu Yungang would definitely want them to pay with their lives. However, the man who was going to kill Wu Yating had a very deep background and Wu Yungang would not be able to take him on himself. He would have to implicate Wang Mingyang. All of this would only lead to one outcome. Wang Mingyang, who was loyal to Wu Yungang, would join in to attack this man and it goes without saying that they would be utterly destroyed.
