With Ye Qiu's current strength, it seemed unlikely he could completely resolve everything here. So, for now, he thought it best to let the others leave first.
As for the missing workers and security guards' remains, he believed they should be underground, within the so-called palace he saw, which in reality was inside the crystal coffins below.
Zhao Ruxue was investigating the case, and now knowing the missing persons were below meant she would definitely want to unearth them.
There were excavators on site, and they could quickly unearth the crystal coffins below.
When Zhao Ruxue went to find help, it was already Sunday, and Ye Qiu had to be at Jin University the next day, so he could only accompany Zhao Ruxue today and would not return tomorrow.
Moreover, even if he came back, it wouldn't be of much use.
As for the police, once they identified the remains and matched them with the families' DNA, the case would be solved.
