Event Gem Farming Day 1

I accidentally saw a post from someone else today mentioning some notes, and that's how I found out about this event. Luckily, it's not too late. (⭐Only 1 post per person per day counts. You need to 'complete 5 posts within 5 days'. 10 comments during the event period!! Only the first 15 people to join the group will qualify for the event.)
