When the beam of golden light fell down onto Faust, no one in this room was able to react. Well, it wasn't no one at all, but the person who could act didn't want to act.
This was supposed to happen, so naturally it wouldn't be in his best interest to go against fate, even if he was a bit unwilling to accept it.
Faust didn't even have time to react as the beam of golden light fell onto him, he didn't even have time to make a sound. At the very least, that meant that he didn't feel any pain at all as he turned into ashes, disappearing without leaving a trace.
Though for Lin Fan, this wasn't what he wanted to see since Faust had been just about to say something that he felt was important. But at the very last second, this strange beam of golden light fell down on him and turned him to ashes.
After Faust had disappeared, the beam of golden light also disappeared.
The surrounding area turned silent and it was like nothing had happened at all.
