Resentment

William's gaze froze momentarily when he noticed the tiger and the seemingly ordinary rock by its mouth, "Is that number 0?"

Based on the intel acquired, the apostle responsible for the theft of the aerolite fragments, number 0, had the power to mutate into different animals.

Tigers definitely did not exist in this part of the world, which meant that he was number zero. From there, William even deduced that the rock was the aerolite he had been searching for.

Meanwhile, Zhao Yao had assigned William a new mission via his illusion.

"Defeat the seven supercats standing in front of you and you will be rewarded with strength + 0, speed + 0."
