When Elyndra saw her strongest attack being easily sealed and then turned into particles of energy, she felt a mix of emotions. It was within her expectations that Ainsworth was stronger than her, yet the way he overpowered her made her feel as if the gap between them was something she couldn't bridge in her entire life.
Or rather, even if she improved her power and surpassed Ainsworth, she'd only be able to surpass his past self and not his present. Since she could improve her power, there was no reason for Ainsworth to stagnate.
After the pot's lid collected the particles of energy, it gathered and concentrated them, and under Ainsworth's control, he used his God-Level Cooking talent to use them as ingredients.
As Ainsworth became stronger, the more techniques and skills he could use from his god-level talents, especially those like the God-Level Cooking talent. Such god-level talents had advanced skills and techniques that could only be used if one had a sufficient power level.
