Ender Dragon Battle in My Coop!

there's an enderman Wait what Why is it here The enderman sector suddenly appeared in my chicken coop And I don't know how he could spawn in this place I tried to kill him and he dropped an ender pearl This is a reminder for me to keep moving forward to achieve the goal we want So I added my villager population again And while waiting for these villagers to grow I'm farming XP to upgrade enchantment tools and also my armor
