Liu Zilang did not shoot not because he could not shoot. Rather, it was not time for him to shoot yet.
As long as he remained hidden in the guard tower, Vampire who was below him would not sense his presence.
Typically, a player would search the guard tower after climbing up the slope. However, Vampire had been distracted by M4 who was below him. Compounding to that was the fact that he had not been ambushed from behind, he had a subconscious idea that the guard tower was safe.
After a short while, Vampire was seen sneaking downhill to loot his opponent's crate before he sneaked up the hill once more.
Liu Zilang snickered as he watched Vampire run uphill with a set of brand new equipment. He imagined that he had picked up lots of consumables too.
He was happy that he had found a 'part-time helper'.
In more professional terms, he was currently the owner of a 'pig farm', and he was fattening his produce.
