Is it worth playing....

Collect your idle rewards in the morning, afternoon, and evening. Focus on leveling up 2-3 heroes, like SS-tier damage dealers and supports. You'll clear the hidden stages up to chapter 21 in no time. Games like this are common in Wuxia and Three Kingdoms genres. I'm already playing a Three Kingdoms game, so I cleared chapter 21 and uninstalled it. If you plan to play long-term, join a guild and spend around 10-30 USD. You'll have plenty of fun. Enjoy the game!
