First look at the plants. The only ones that can be used are Caiwan and Flame Peashooter. Looking at the map again, the plant in the last column is the brand-new Overlord Flower, which has a strong range of damage capabilities, but the attack speed and bullet flight speed are relatively slow.

Then there is the position of the ice floe. It can be seen from this that the only route that the zombies in this level can walk is the line below, and the rest will be forced to move to the position of the red box.

Since the flame pea shooter will not be frozen by the freezing wind, but also has the function of heating the surrounding plants in a short time, therefore, the two flame pea shooters should be placed in the back row at the position shown in the picture first, so that the backyard can be There was a fire, so we were relieved (something was wrong).

When there are too many zombies around, using Caiwen's special move to gather all the zombies together and beat them up will have a good effect, especially in conjunction with the attack method of the Overlord Flower.
