Tang Shaoyang was disappointed deep inside that the mutant had such a big flaw. The mutants were even in much worse situations than the monster or even calamity. However, their situation could not draw his sympathy for them.
It was something they chose for themselves, he did not care about their actual situation. Everyone had their own paths, and he was not in a position to have compassion for his enemy. In fact, he was disappointed that they did not live up to their reputation.
From Torben and Prodan's reaction, he expected a good fight from the mutant. With how Khaya reacted when he said he would fight the Void Cult. He had a high expectation for a good fight. They were strong, but they had a big flaw. The flaw that he could use against them with ease.
Tang Shaoyang used Absolute Domination Energy, and the cracked space around him disappeared. Caeso was within range of his skill. The Void Energy that wrapped the four swords also dissipated.
