Jack Clark knew he was referring to the matter of slaying the Demon God, and he shook his head slightly, "Actually, luck played a part in that encounter. If the Demon God I had faced had been from the Ancient Middle Stage, I definitely wouldn't have been able to slay it."
Among only the Primordial True King and the True King Heavenly King, who were his own people, Jack Clark did not display modesty.
The reason he could slay that Demon God indeed had a great deal to do with luck, as he had the advantages of the right time, place, and harmony with people.
"Harmony with people" naturally meant that his opponent was just in the ancient early stage realm, and Jack Clark overwhelmingly outmatched him in overall strength, while "advantage of place" was the shielding provided by the tens of kilometers deep Earth below.
