All four ranches were under Luke's name, and he didn't give them to his grandpa directly.
Although he didn't care about that, the stubborn old man obviously did, so Luke simply entrusted the ranches to Drax.
Robert had already talked to Luke about it, and after bringing up Luke's idea, found a professional to take care of it.
Faced with a ranch that had expanded four or five times in size, Drax could only follow this suggestion.
His original plan was to buy a neighboring ranch.
Luke, on the other hand, had thrown in four ranches at once, which was much more than he had expected. The old man really didn't have the energy or manpower to handle such a big scene.
Recently, the manager had taken over the ranch and had a lot of work to do.
