In the first week, I secured a hydra lair and built it up in my castle, resulting in 121 hydras. In the second week, I built up hydras in a secondary location, resulting in 131 hydras. Next to the castle, there were two utopias, one of which was fully upgraded. There was also a library nearby. After a couple more days, everything would have been perfect, but on day 133, an opponent attacked with 3 archangels, 30 wyverns, and high stats. Even with all my troops, I couldn't put up a decent fight, even though I was confident in my victory just a turn before)))
Thanks for the game.
