1. First of all, the back-to-back array is characterized by its strong steering ability. If you don't play well, it is difficult to get into the inner ring even with the rebound medicine meat shield.

2. Then the disadvantage is that the utilization rate of city walls and traps is low.

The advantage of this array is that the innermost wall separates the queen from the black pitcher, and the queen can't reach the black without breaking the wall. Fire coverage is good, archers can't steal it except in the laboratory.

4. After using this array of black water jugs, it hasn't been blasted, but it was still knocked down by the 4 earthquake and 20 Valkyria, and all the defenses in the inner ring were swept away by wild boar.

5, let the queen turn around the black water cylinder, and was also attacked by a four-day-old girl.

6. As a result, the queen went out and was beaten once a day. Most of the attackers were imitators and heavenly daughters. Don't use it on the ninth day.
