My Dragon Power is over 22,000, but the Bingo board got harder 🥺

Because of the Sparkling Day event, I raised my Dragon Power quite a bit... and now I've met this Bingo board after reaching 22,000! This Bingo board's difficulty has increased ㅠㅠ I used to only do up to the first row on the 3rd Bingo board... But to do that now, I need to raise my Dragon Power from 100 to 150... (It's best when it overlaps with the Sparkling event, but if the event dates don't align, raising it to 150 will be tough again) I also need to spend 15 to 25 Gems... And create a Level 3 Dragon... I can manage the other tasks, but the last row of the second board has made things annoying lol During the Portal event, I could get the final rewards just by purifying about 1/3 to 1/4 of the land with a low-level Purification Orb... But now I have to create a Level 7 Giant Life Orb... what a hassle lol I'm even considering giving up on the Sparkling Day event and just not raising my Dragon Power, but I still want to purify all the camp land. Only about 35,000 land is left ㅎㅎ It's getting harder and harder ㅋㅋ
