It's not that I don't have anything better to do, but... I just can't help but notice things like this.
ROCH Chapter 37:
Guo Fu stepped up to the platform to check on dead Huodu. Suddenly Huodu leaped up and striked down at her. At this time, it was said that Guo Jing, Huang Rong, and Yelu Qi all tried to race to the platform to save her, but they didn't have enough time.
Now, it is my opinion that if Guo Jing were capable of LDA, he would have thought of it rather than trying to physically race to the platform. The distance to the platform is unknown but I don't foresee it more than 30 feet.
