While those three bodyguards weren't around, Woo Tianhao wanted to finally test Fang Zhao's fighting skills before Fang Zhao left planet Wai. Who knew when his next chance would come once Fang Zhao left Wai.
Yet reality was a crude awakening for him.
The first time Woo Tianhao tried to ambush Fang Zhao, the latter was walking back to his dorm from the base cafeteria. He was discovered way before he even came close to his mark. There was no ambush to speak of because he was busted.
Failed attempt.
On his second try, Woo Tianhao decided to switch tactics. He would confront Fang Zhao directly.
The most famous skill of the Woo family from Tongzhou was their ability to shatter rocks with their bare hands. A senior member of the Woo family had demonstrated the method on a TV show several decades ago. Decades later, the rock-shattering chop was still what folks remembered the most when the Woo family was mentioned.
