Jia Mu had already decided that, once he killed the boy by the riverside and retrieved the ten-eyed treasured pearl, he would immediately return to Ming Zhu Temple in Tufan Province, and he would not linger in Shen City for even a moment longer.
After retrieving the ten-eyed treasured pearl, unless he encountered a personage of the True Immortal level, he, Jia Mu, would fear no one.
Jia Mu's figure appeared by the riverside, then he turned and slapped with his palm.
He had already calculated that at this moment, the person should be rushing right behind him, and would directly collide with his palm.
As for why he chose to intercept him at the riverside a step ahead rather than chasing behind him and striking with his palm, he was also worried that the opponent's iron arrows would slow him down, thereby giving the person a chance to rush into the great river.
