Gao Xin knew he couldn't kill Rousi.
This woman's ability was bizarre; aside from the Demon Blade, he had no means to harm her.
That is to say, his Meteor Crossbow was almost rendered useless.
You should know that he still had several deadly moves that relied on pushing the Meteor Crossbow to its limits, risking his life.
But since he couldn't hit her, of course, he couldn't use them, otherwise it would just be a waste and it would only weaken him.
Now even the plasma was drained, and the Demon Blade just had its pure slashing effect left.
Gao Xin estimated, "Even if I create an opportunity to successfully slice into her brain, without the plasma damage, I fear she wouldn't die immediately."
"She might even be able to heal the severed brain stem..."
"This woman is too strong, I can't kill her..."
He no longer had the means to kill Rousi, and he didn't even have an 'image' of defeating her in his mind.
