Lin Mu who was battling his confusing at his previous attack was surprised by the sudden words of Xukong.
The Spider hadn't spoken or talked to him at all, during his battle against Yao Changying or when he had been attacked with a Soul Skill.
It was as if Xukong was not worried at all, which was in fact correct.
The spider knew more than everyone and had already expected how the fight would likely go. He had anticipated several different scenarios, including one where Lin Mu would get targeted by a Soul Attack.
In fact the Withering Dao was known to have several skills that could target souls, so it was expected Yao Changying would have one.
Xukong had chosen not to advise or interfere, knowing that Lin Mu would be able to handle it all on his own this time.
But he finally had to speak, seeing the destruction he had caused, which likely had injured many people as collateral.
"A Megaquake?" Lin Mu repeated in confusion.
