After entering the river, the water reached Lin Zhen's chest.
Before Lin Zhen could even steady himself, a wave driven by the waterfall slapped him.
Lin Zhen didn't take it too seriously, as this small wave couldn't topple him, so he held his chest up and braced for the wave's arrival.
However, he overlooked one detail - the riverbed wasn't made of mud, but of slippery wood. When the wave struck, Lin Zhen slipped and fell, swallowing a few mouthfuls of water on the spot.
"Cough cough cough!"
Lin Zhen stood up in embarrassment, wiping the water off his face with his hand.
"My lower body still lacks stability. When I was learning spear techniques from Zhang Guanyue, he once told me that practice without improving your waist made you an ultimately poor martial artist. Having a stable lower body is crucial for a Martial Artist. My immovable like a mountain technique has been well-practiced, but that's on flat ground. On this slippery riverbed, it's not as effective."
