Shu Yu wasn't the kind of person who relished killing. In the past, because his body was too weak, he was a dying invalid. Even if he had a conflict with someone, it was always the other person trying to kill him. Although he had a sharp mind, if outwitting didn't work, he could only lie down and wait for death. Fortunately, he never experienced such a thing.
However, later on, even when he developed Inner Strength and the ability to protect himself, this person hid it too deeply. At first, apart from the Eldest Brother, even the wife master and other brothers were completely fooled by him. Even after everyone found out, he rarely used force to subdue anyone.
Mainly, one, he was lazy, extremely lazy. If he could lie down, he wouldn't sit; if he could sit, he wouldn't stand. For someone so lazy, unless there was a real need, why kill people? Haha, it was better to just snuggle up with the wife master and take a nap.
