Outside Lin Zhen's tent, someone has always been living in a tent.
The tent has a huge hammer mark on it, and similarly, a red hammer mark is drawn on the tent where Lin Zhen is located.
Any ordinary Martial Artist looking would immediately turn and leave, even showing sympathy for the situation of Lin Zhen's tent.
The owner of this tent is unlucky enough to be targeted by the Eight Great Hammers; it looks like trouble is brewing.
The red hammer represents imminent aggression from the Eight Great Hammers, acting like a death warrant.
Although brawling is forbidden in the safe area, this doesn't prevent them from issuing a death warrant on Lin Zhen.
Other Martial Artists, not wanting to offend the Eight Great Hammers, move away from Lin Zhen's tent. After all, it's not always safe to stay in the safe area; better safe than sorry.
