Joan assimilated with Duplicate. That means, everything that Duplicate has will be Joan's. His stats were greater than him due to him collecting more monster essences he killed on his adventuring. While Joan was in the academy to become stronger and train on what he has currently. Relying only on [Stat cultivation] to increase his stats but Duplicate outranked him with him getting the cream of the crop.
There were monster essences on the field than in the academy. It was a fact that Duplicate will become stronger. Still, he hoped that Joan will still become stronger than him. Resulting in their small test of strength that resulted in Joan's defeat.
Still, his stats were not stopping from rising. It felt like it was just starting. Joan then felt that he will soon ascend to a high-tier Grandmaster. The same as the peak of his past life. Even though he became like it sooner than expected, he felt that it was too soon.
