Mike thought to himself....
He was already very satisfied with the three blueprints that had dropped during the previous Battle of the Castle Guards.
Furthermore, he had killed over a hundred elite-level twin-headed demons and dropped four strange crystals. He could be considered lucky.
"So far, I've stored close to 2,400 energy stones and 25 strange crystals."
"That's good! I'm one step closer to upgrading the dragon nest!"
Mike was eager to upgrade the dragon's nest to level-4 as soon as possible.
In this way... He would be able to hatch another dragon and fight for himself.
Moreover, at that time, he could prepare to build the dragon's guardian shield for the Dragon King Castle.
With the dragon's guardian shield as a defensive shield, not only will Caesar no longer have to stay in the castle, but he'll also be able to go out and see the world.
