Help me out hereeee!

I only know Lan, so I don't think I can offer any suggestions, but it might be easier to answer if you post screenshots you have! (Hoping for the experts to chime in)

First, choose one main attacker from the characters suitable for attackers. Focusing your育成 (training) resources on that one attacker is the easiest way to clear the game. If you assemble a team with one of the attributes blue, red, yellow, or green, an attribute bonus will activate. If you gather up to 5 characters of the same attribute, your HP and attack power will increase by 25%. (The 'Heaven' attribute can be treated as any attribute you like.) Therefore, a good formation is to center it around one attacker, adding characters of the same attribute and support roles.

Oh, I see~ I didn't know what it was either and just enjoyed it, but there are ways to set up teams and differences like that. Can I ask another question~? I'm stuck because I don't know how to evolve characters past level 100.

Just in case, I'll post my current inventory! I have more, but I can only upload one pic 🙏

I have no idea about so many things, but I'll give it my best shot.
