Nobody expected that Gold Horn and Silver Horn would initiate an attack just because of a malicious word from Daoist Mo Luan.
In fact, the Dragon Pythons of Fire and Ice were known to be the fiercest creatures under the heaven. The brothers only feared Wu Qi. In their eyes, the rest of the people were merely food. After going through the Thunder Tribulation of Ice and Fire, they had inherited the legacy memory from their bloodline, and even inherited the savage, unreasonable manner of Dragon Pythons of Fire and Ice. Because of that, there was no reason for them to not initiate an attack upon hearing Daoist Mo Luan's curse.
It was a deadly attack, as they never showed any mercy when decided to attack.
