How does SD gundam OL get Z gundam?

Z Gundam is divided into two types, one is gun outfit and the other is sword outfit. Gun outfit can be synthesized, and it can also be drawn from an egg twister, while sword outfit can only be synthesized. If you want to synthesize, you must first buy drawings from the shopping mall, then click on the drawings to see if there is any synthetic body material on the left, and then you can draw in Newegg Mall.
