In an abandoned factory in the west of Capital City.
There was no one around the abandoned factory, and ordinary people would not notice this place at all.
However, if Ye Chen was here, he would definitely notice that there was a formation under this seemingly ordinary abandoned factory, which was powered by a drop of blood essence.
Ye Chen's blood essence!
This abandoned factory was Ye Chen's backup plan for Huaxia's Dark Hall.
When he had left Huaxia, he had been worried that something might happen to the Dark Hall. Even though the Dark Hall was the strongest force in Huaxia, he still made this backup plan.
There was a powerful concealment formation outside the abandoned factory, which made it very difficult for ordinary experts to discover it. In addition, there was another space under the factory, in which there were spirit stones and various technological equipment.
It was extremely difficult to break into.
