Originally, Jack Clark had estimated that creating a Time Mark as a Heavenly King would cost more than ten times that of someone at the Mythical Peak Realm.
Three days would be enough to condense three Time Marks, increasing his combat power by three Demon God Level figures from the Ancient Middle Stage.
But who would have thought that after reaching the mid period of the Heavenly King Realm, the cost to form a single Time Mark would actually skyrocket to more than fifty times, causing even Jack Clark to feel somewhat of a headache.
If it weren't for the Space-Time Summoning Secret Skill, and he had to capture the Power of Time using Time Reincarnation Mystic Power regularly, Jack estimated it would take ten years to form one Mark.
It was that exaggerated.
Of course, this pace was slow for Jack, but for other Heavenly Kings or Great Demon Kings, it was ridiculously fast.
