Up to 3 silver bells can now be used at the place of training of the silver bells, which was the maximum of 10 until now, at the Temple of God. Even if the experience value is doubled, the level 2 → 3 did not reach the maximum with 1000 in the present situation. However, since it is a half-hour campaign, it will end in 1500 minute 1 seconds. Let's use separately.
Level 2000 is also one shot. But if it's still in the double campaign, it's better to use 3 separately. Below are three images. However, 3 pieces x 3 does not reach MAX, so it seems that it will be 2 pieces in total, 2000 pieces, 3 pieces, and 3 piece, in order to reach level 1.
If the experience value is doubled, it seems to be worth using from 2 to 2000
