Ludwig meditated. Two days passed when he heard a knock outside his room.
He stood up, looked at himself. When he saw that the robes were clean and orderly, he smiled and stepped out 'How convenient.' Then he went to his table and willed spiritual power to open the door for him. He wouldn't do something like this himself.
The door opened and two young people came and cupped their hands to him "Greetings, elder brother! We hope we didn't disturb your cultivation!"
"You are too formal, come and sit."
The two nodded and went forward, sitting in front of Ludwig. They didn't hesitate and came to the point "We both calculated the natural positions. Now, we only need to make arrangements for the formations we are planning to build."
Ludwig nodded "That's good. As for the formations we build, say, how large could our formation be? For farming, especially large scale, we need a lot of space."
