Your primary card (blasting card) level is too high

. If you don't strengthen the secondary card, the success rate will be very low. (It's easy to understand after playing the food war with mice)

First, strengthen the secondary card to a high level (do it yourself, don't be too high, or you will lose money), and then strengthen it (if you don't feel at ease, you can add a strengthening stabilizer).

hope to adopt.
