How do you synthesize characters?

The synthesis process is very simple:

1. First, get elements from the Conveyor Belt at the back of the base.
2. Then, walk to the Crafting Table on the other side of the conveyor belt.
3. Press the E key to interact with the crafting table and open the synthesis menu.
4. In the menu, select the elements you own to combine (up to 6 different types can be used at the same time).
5. If the combination is correct, you will successfully synthesize a new anime character.
