Can I still get stronger?

A million attack power is a very high goal. Besides equipment, multifaceted strengthening like collections, tech parts, and survivor training is essential. Let's build it up one step at a time without rushing.

Is it because of the repeated divine forging? I can't think of anything else✨ Since you seem to have a lot of Swords of Chaos, how about Chaos Fusion?

I have the impression that you can collect quite a lot with custom collections.
