Shopping strategy
The items in the fighting mall are cheaper than the ground seam, and the cost performance is extremely high. In particular, Zigui orange is expensive, half cheaper than sewing, and the accelerated research is the price of cabbage.
Adhesive is a little more expensive than shopping malls, but it is also worth buying.
Purple handwriting, a resource with limited output, huge function and huge gap, must be exchanged with life.
The purple brush in the crack battle must be full. Orange is more precious, so try to change it.
