An actual Mysterious Underworld being!
Back in that training facility, Luo Yunyang had seen a simulated projection. Although that image had been very lifelike, something fake could never be real.
Even under the circumstances, upon seeing a being from the Mysterious Underworld Race, Luo Yunyang felt immediately hatred get etched in his bones.
This sort of animosity wasn't for him. It was an animosity buried deep in his bloodline. A hatred that was difficult to dissolve even if many eons passed.
His cultivation base was insufficient and the missing parts of the training facility were difficult to repair, so Luo Yunyang hadn't gone searching for the Mysterious Underworld Race.
However, he had always been paying attention to the decline of the Mysterious Underworld Race.
Unfortunately, the Divine Union had no records or memories of the Mysterious Underworld Race, and neither did anyone else.
