Xiao Fei's body was moving at a very fast speed, without the slightest resistance from air, as if it was a form of light. Shu XinYi was having difficulty tracking it's movements, but Shu XinYi kept his mind and eyes both open and focused. His forehead started sweating carrying the weight of an almost weightless sword. But Shu XinYi didn't show signs of hindrance, instead he continued to give his 70% with consistency. The sword though was giving it all, but even now it was not fully powerful. If a seal had not been set, then Shu XinYi wouldn't be able to stand even for a second.
