The reason Gongsun Jing was at a loss for words was that he indeed couldn't provide evidence that Lin Fei killed Gongsun Wenhao.
That's also why he wanted to use force to capture Lin Fei back to the Gongsun Immortal Sect.
And the reason Yang Fan dared to say this was because he knew from Yang Tong and Yang Pingting that there was no evidence left with Gongsun Jing regarding Lin Fei killing Gongsun Wenhao.
With no evidence to confront, Gongsun Jing wanted to handle it fairly, which Yang Fan had no objections to.
Gongsun Jing could only stubbornly say to Yang Fan, "Brother Yang, I might not have evidence now, but I will definitely find some. By then, I hope you won't stop me from capturing this kid."
Yang Fan smiled and said, "Sure, as long as you have evidence, you can come anytime."
Gongsun Jing looked at Lin Fei with an unwilling and resentful gaze, warning coldly, "Kid, just you wait and see!"
