we all know that the blue print is coming and it will be huge

For those who does not know, what recursion is - it is function that call itself. In our conditions, it will be blueprint with itself

So now you will do this : In the yellow rectangle you select what you want to your blue print (just what the creators shown us), but you can also place there two items : "blueprint start" (green square) and "blueprint next" (red square). When you place it somewhere the construction drones first place blueprint on green square and then start building the blueprint. After they build all, they take blueprint from green square to the red square.
When it is placed to the red square, the whole blueprint is built once again considering red square of the previous step as green square in the current step. So until robots can build and you dont stop this, they will recursively build this concept to the south.
The interesting thing can happen, if you place multiple red squares to recursively desing your concept in more directions. Something like this :
After robots finishes the design, they copy blueprint to the 4 red squares and there they start buildling it once again. Like before, the position, where the blueprint is placed is considered as "green square" position in the concept.
This one will create fortress in all directions creating a huge complex after some time (could be interesting to get far into enemy teritory and start building this)
