His dad knew that of course.
Originally, he wanted Jiang Feng to assume power in the Animal Arena so that he would get some assistance.
But when he saw how serious his son was, he sighed and said, "Alright, Little Feng. You have to be careful!"
"Of course," Jiang Feng nodded.
His dad then scanned everyone that was present and said, "The Animal Arena has remained hidden for so long, and this evening is the time for everyone to gain a new understanding of us. We will gather here this evening at eight. Our objective, the Xuanyuan family!"
Hiss!
When Ling Yuntian heard his dad's words, he breathed in a mouthful of cold air. He quickly stood up and said to him, "Brother Jiang, are you mad? You want to attack the Xuanyuan family? Do you know how powerful the Xuanyuan family is? You are committing suicide if you were to attack the Xuanyuan family!"
