Which part of the human body, or acupoint, will be killed, maimed or injured? And the magnitude of the force.

Hit the heart with a hammer, indicating that you can try your best to shock or kill others. Also, your fingers can be flattened into a strong palm at the throat, and the palm can be straight up and down at the throat. Don't kill too hard. There is also boxing in the middle of the bridge of the nose, which will make others cry all the time and give others a chance to do it. Generally, there will be no big injury, most of which is a broken nasal bone. You can hit the lower abdomen hard with your fist, which will make others feel unbearable stomach pain and will not cause great harm.
