Wu Di justified his reckless behavior in Chang'an City under the pretense of "testing skills".
Any immoral act that he could think of and was allowed by the system, he basically had done them all.
Unfortunately, his mentor, Master Han Jing, had never given him a weapon.
Despite the fact that the people of the Tang Dynasty were allowed to carry weapons at will, Han Jing insisted that "weapons should not be given lightly", and only after completing the entire training of the "Assassin's Way", one would be qualified to use the assassin's weapon.
This greatly limited Wu Di, preventing the ideas in his mind from being put into action.
Like kidnapping the bathing beauty he saw that day and making her his wife.
Of course, this also demonstrates from another perspective that "weapons should not be given lightly" is indeed a very necessary principle...
