"The Ancient God of Energy," when he acted that time, was indeed venting his rage, which showed his immense anger at someone daring to challenge his status and snatch away the source of his Law.
But such fury only prompted a momentary action.
It was merely about crushing Emperor Wu to death.
Even contaminating a large amount of the Great Wu Army was just a stirring of the unfinished Law, causing the pollution to spread unintentionally in his rage.
Perhaps, ordinary people would think that the Ancient God disdained to act.
But Shen Hao understood that for the Ancient God, crushing all life in the material universe was just a matter of convenience, not reliant on a mere over-40-level Extraordinary level but on the "Extraordinary Dayuan" of the entire universe.
Therefore, the fact that he did not do so warranted deep thought.
