Hidden Quest

There's a hidden quest to obtain 'Burning Re-fusion', and it's not even a purchase quest, yet it gives a reward of 70,000 coins?! 🫨 So I kept looking into what this was all about, and it seems like you have to spin the roulette and get the one marked 'Limited' at the top 😅 There's not much time left, and if I don't spend money, I can only get one roulette ticket a day by watching ads 😢 Honestly, unless you're incredibly lucky, you might not even get it even if you pay lol. I knew the reward seemed too good to be true 😭 But the Mecha Roulette event only has 6 days left, so why is the 'Plu' hidden quest still 40 days away? 🤔🤔 Anyway, I'll try every day for the next 6 days... but it's probably impossible to get it lol ㅠㅠ
