On day 123, I collected the respawn, resulting in 9 Angels, 44 Wyverns, and 3 Red Dragons.
On day 124, I kill ГО, immediately take the Dragon Utopia. I approach the central town and see that the opponent is already there.
On day 125, the opponent takes the Dragon Utopia near the town, stays there; I attack, and a surrender follows. I collect the remaining goodies and spend the night in the central Castle.
The next turn, the opponent surrenders. Thanks for the game.
