Tang San smiled slightly and said, "I call it a sleeve arrow, also known as a silent sleeve arrow. You just need to activate the switch, and the three small arrows inside will shoot out under your control. You can fire one or all three at once. Because it makes very little noise when activated, it's not easy for the opponent to detect, so it can be very effective against enemies of similar strength."
Xiaowu exclaimed in surprise, "How come I've never seen you use this during our sparring sessions before?"
Tang San smiled faintly and replied, "Silly girl, we are classmates and friends. How could I use such a lethal weapon on you? Do you remember the time I hit you with a stone? Do you think that was just a coincidence? Look, there's a mosquito over there."
Xiaowu followed the direction Tang San was pointing and indeed saw a mosquito buzzing by about three meters away, barely visible in the moonlight.
