The natural energy was used to create life, while the destructive energy was used to create ghosts. Thus, strictly speaking, the destructive energy was a type of death energy that was of a higher level than the black energy in hell. Thus, it was normal for the black energy to fuse with the destructive energy.
However, to Zhao Hai's surprise, even though the black energy had fused with the destructive power, a small portion of it had fused with the natural energy.
Zhao Hai had always thought that the black gas was a kind of death energy. He did not expect that there was a trace of natural energy in the black gas. In other words, the black gas was a kind of energy that brought life from death, not complete death energy.
However, Zhao Hai understood after thinking about it. It was not strange for the black gas to have a trace of life energy. If there was no such life energy in the black gas, then there would be no ghosts. Ghosts were created by the life energy from death.
