Watching Liu Dongjun's palm striking towards him, Xiao Yi's mouth curled into a hint of scorn.
The moment Liu Dongjun made his move, Xiao Yi had already known that his strength had definitely not surpassed the Middle Tier of Bone Tempering, and his Iron Sand Palm was only at about the Third Layer!
He was actually quite familiar with the Iron Sand Palm.
A long time ago, when he had seen a martial arts film on television and out of curiosity had asked Old Man Xiang about it, the old man had not only answered his questions but had also impromptu shared a few Kung Fu styles, including the Iron Sand Palm, with him.
On that occasion, he not only told him that the Kung Fu displayed on television actually existed in reality, but he also explained the features and power of several techniques including the Iron Sand Palm.
So, the moment he saw Liu Dongjun's technique, Xiao Yi knew to what extent his Kung Fu had been developed.
