In today's age 100k per day is doable very much so. With the humans as they are now I can could make 200k per day at 1100 acres. I had a human that was 1400 acres that was making over a mill very game day and making over 24mill every month. I did all that bad they 3rd year. But my pc go messed up so I had to take it in. That was back when sage had full protection from learn attacks. The next age they made it so sage only had 50% protection from learn attacks. Now sages have 60% protection. 100kgc per day is very doable.
