Wang San struggled to get up, the dizziness in his head not yet completely dispersed. It might have been due to fear, or maybe pain, but either way, all the muscles in his body trembled. There was a pool of blood on the ground, extending from his own feet out the door, and not far from this pool of blood, there was a gun.
Wang San was a man who didn't like to think things through. To put it in the words of the people around him, he was like a "beast." If translated more nicely, that meant he was simple, direct, but not necessarily effective.
So according to the current situation, his brain instinctively made the following thoughts:
1. There's someone outside the door.
2. He wants to kill me.
3. There's a gun on the ground.
These three things merged into one very simple, direct conclusion, which was: "Damn it! I'm going to take him down!"
