Ranger - "Higher Vampire" [5th Campaign, 5th Mission]

Guys, please help. Nicholas came with 7000 dragons, not counting the smaller units.

With 7000 dragons, that's nothing. I have 17,000 dragons, 36,000 skeletons, etc. against my 230 black and 90 azure dragons, etc.
And try to defeat him.
Maybe someone could send me a save file after completing this mission. to
