Is Legend of the Phoenix free to play?

Excuse me, I was wondering if you could clarify something for me. In regards to the game titled "Legend of the Phoenix," I'm a bit unsure about its monetization model. Could you please tell me if this game is free to play? Are there any in-game purchases or subscription fees required to access all its features? I'd appreciate any information you can provide. Thank you in advance for your time and assistance.
