This was the rule!
There were over ten thousand people in the yin-yang headquarters, and there were all kinds of people.
If there were no rules, with so many people who were all eccentric martial artists, sooner or later, there would be big trouble.
Every yin-yang had an identity card on them. They had to leave traces everywhere they went.
In the future, if something happened, it would be easier to investigate.
It was precisely because of these rules that many yin-yang people who had grudges against each other did not dare to mess around in the yin-yang headquarters and were well-behaved.
The black-robed martial artists kept leaving with their dishes, ignoring Luke Yates.
There was no such thing as helping each other in the yin-yang headquarters!
They were all trying to get into as little trouble as possible!
