The underground palace was relatively dangerous, but Ah Yu had to go. She originally wanted to go in with only City Lord Wan, and King Xiaoyao. But other than herself, no one else agreed.
There was no need to talk about Tang Yuan. She wanted to follow Ah Yu closely, afraid that she would be harmed in an unfamiliar place.
Even if her martial strength was completely inferior to her little master's, at the very least, she could help her die at the critical moment.
Wang Wulang and the three Crimson Guards naturally would not stay. They also had the same thoughts as Tang Yuan.
On the other hand, Xie Zhen thought for a long time and felt that his martial strength and intelligence were not good, especially since his luck was not very good. It might be better if he did not go.
