In the first and second weeks, he almost gave up several times. But in the third week, after taking the Castle, he couldn't find any oil (he built a Grand Mage in three cities, checked all shrines, and collected all scrolls), and he only had 30 Grand Mages and 17 Dryads left after the Grand Order. He only had one Town Portal scroll, obtained from the second building in a city. The opponent didn't have any control. (If the Town Portal scroll had appeared equally, the game wouldn't have been winnable).
Thank you for the game.
