In the original god color festival event, in addition to some of the rewards of the mission gameplay, there are also many easter egg rewards. These rewards are obtained through dialogue with NPCs and should not be available after the event, so I hope you don't miss these rewards.
The first is to talk to Kurisu and always choose the first one about yourself, and you can get the guidance x1 of prosperity
Talk to Yegor and choose "What are you bothering about?" Miss Ryoko?" Strange kebab steak x4 is available
Talk to Ryoko and choose "Your cooking skills must be very good about this shop, right?" Dry roasted ayu x4 is available
Finally talk to Harrison, which can only be used at night in the game, and choose "Good Stuff...?" Then keep talking", which can get the golden guide x1
In addition, there is an interesting little Easter egg, after the end of the plot mission of the Rongcai Festival, in the Wuge Immortal Square, the black lord's painting is wet with water elements, and the original painting without characters will show the characters, and when the water dries up, it will disappear again, this detail design is really very careful.
