The killing such as this one was just a common occurrence back when Tang Xiu lived for 10 millenniums in the Immortal World. It was the world where bloody brutality was just common sight between all walks of life that fought and killed each other—the manifestation of the rules of Heavenly Dao—just like big fish preys on small fish and small fish swallow shrimps. Even if you don't resort to killings, some others will come forward to kill you. Those who wanted to live and go further and those who wanted to be stronger must inevitably step on the mountain of corpses and traverse through the sea of blood to move forward.
This island had over 1,000 inhabitants and for the former Tang Xiu, this cruel battle might be less brutal than what had happened to those innocent victims. He valued life, but that didn't mean he must care about the lives of the damned people who deserved death.
