Martial Grandmaster

It took 2 hours to perform the first move, three hours for the second move, and 4 hours for the third. A full cycle of practice was 9 hours, and when Dante was done, he felt completely rejuvenated rather than fatigued, which mostly had to do with the Quantum Vitality Serum rather than his practice itself.

When he checked his progress, he saw that he had made 5%. This was a steep increase from the 2 hours for 10% he had at the previous Advanced Knight Realm, but it followed the rules of higher realm = higher effort.

Anyway, with his current ability, it was a piece of cake to bring his Primal Ape Technique to breakthrough to the Great Knight realm after spending just over 81 hours or 3 and a half days practicing nonstop with no break.

After all, Dante at his current realm did not feel much physical fatigue, while his mental fatigue was greatly alleviated by his quantum clone, who was peacefully meditating using the expensive incense in the Black Land.
