The so-called mental destruction law was not a mental victory law. The mental victory law referred to a way of self-deception by making excuses for oneself when one was unable to defeat the opponent. On the other hand, there were many kinds of mental destruction laws, and each one was different. For example, when the police persuaded prisoners, they would not let them sleep deeply. They would give them food and water, but not let them go to the toilet. In the end, the prisoners would have a mental breakdown. This was a kind of mental destruction law.
The mental destruction that Liu TOU and Dao BA had used on Zhao Hai was another method. This method was very strange. They didn't speak to Zhao Hai and didn't let him see anyone. It was like he was in confinement.
