Tang Zhen wasn't trying to scare them. Black Rock City was a good example, and everyone was very clear about it.
If the truth was as Tang Zhen had said, then they would have to fight the corpse race's city. Otherwise, once the corpse race's power was established, they could forget about escaping by luck.
However, the undead's city was guarded by Lord-tier monsters and was heavily guarded. It would be far more difficult to capture and destroy it than to break the siege on Black Rock City. Was it worth it?
Everyone had their own selfish motives. The reason why these city Lords agreed to help in the battle was because they had their own reasons, but no one would do a losing business.
Tang Zhen did not continue to speak as he looked at the four city Lords, who had uncertain expressions. This was because he had already said all the information that he needed to say. As for how they would choose, it was up to these people.
