Having one arm broken doesn't seem to have a large impact on a Yuanwu Expert!
But in reality, in high-stakes duels, a miss by a fraction of an inch could lead to errors of a thousand miles. Now that one of his arms had broken, Ning Wudao's strength was actually weakened by at least thirty percent.
Chen Tang's original strength was at least above the Sixth Stage of Yuanwu, and now, in terms of strength, Ning Wudao was probably no match for Chen Tang.
Moreover, on the first floor below, outside the glass house, another strong man appeared at the peak of the Yuanwu Fifth Stage, Meng Shaotao.
This guy, in his combat form, had a vague outline of a suit of armor appearing behind him, and he didn't bother to dodge other people's attacks at all.
When Yuanwu Experts of the Fourth Stage hacked at Meng Shaotao's back with ordinary warblades, sparks flew, but Meng Shaotao was completely unharmed.
