Level Up Tips

I'm writing a few words because many of you have failed to level up your castles without spending money. After around level 15, it usually takes more than a day to level up. To shorten the time, you'll need speed-up items, which can be obtained from events, the guild shop, or by hunting elite zombies. Most of them are usually 1-minute or 5-minute items. So how do you shorten the time? You absolutely must join a guild with many members. I was lucky enough to join a crowded guild early on, received a lot of speed-up support, and bought 60-minute and 8-hour speed-up items from the guild shop using rally points. These are probably weekly items, so you can buy them once a week. If you do this, you can easily achieve the hidden objective without spending money. I hope everyone can enjoy the game easily.
