At the same time, along with the sniper, two others died: the observer and the intelligence officer.
In fact, if not on the battlefield, observers aren't really needed, but someone has to watch the surroundings and wait at the hotel entrance to see when Sofia comes out and give early notice.
However, the deaths of these two were not as gruesome as the sniper's, just their brains were turned into a mess.
The one who acted was of course Feng Jun, focusing on the sniper because he knows these types have stronger mental strength than ordinary people, having encountered several with strong souls in Mai Nation—the Apostate Keane and Saint Judge David.
Yet he still overestimated the mental strength of ordinary people. With three soul strikes, not only did he kill them all, someone even had their head blown off.
He's somewhat regretful for hitting too hard, but it is what it is, nothing too grave.
