The moment the footsteps entered the carriage, San Wu jumped up. Before she could stand still, her gun was already aimed at the connection between the two carriages. She could quickly kill the other party before they could react.
Even a sharpshooter would find it difficult to do what she did. She needed a fraction of a second of buffer, but San Wu didn't need to aim. Once the muzzle was pointed, she just had to shoot.
If she had lived in the era of the Western Development of the United States, she would definitely be the most amazing sharpshooter. In a duel of guns, the opponent would have been shot to death before he could even draw his gun.
San Wu did not shoot.
A Railway Police officer was standing at the junction of the two carriages. He was shocked by the girl's sudden appearance, and then he was frightened by the dark muzzle of the gun. He subconsciously held the baton in his hand.
