At the bottom of a waterfall, one could see a young man with white trousers and a naked upper body holding onto a silver spear, swinging it in front then pulling it back, the speed kept increasing and the spear become more and more blurred the faster he swung it. In the past three months in this place, Wang's spear use has already gone beyond mastery but not at the level of grand mastery yet. But the use of the spear has become more and more instinctive, in a way he can retreat and advance with the spear at will. And for the silver spear, it was the one underwater, with the continuous improvements Wang's strength especially arm force has reached close to 24000kgs.
