The sliding general attack of the dirty water gate skill can flash to a position where there is no pain, and the roulette control skill can be used to release it. After the past, you will leave pain in the same place. After you release your skills, you can go back to the position where there is no pain, and you will leave a pain in the same place.
If you practice more in the duel field, you will soon master it. Maybe some friends will hit the enemy when they play with the dirty water gate, and the enemy will try to prevent the situation that Flying Raytheon can't go back after his termination. In fact, as long as he presses the general attack, he can easily go back.
