After saying these words, Mike smiled helplessly.
Of course, he said it as a joke. However, it was this joke that made him realize a problem that he had never thought of before.
He suddenly asked the system, "Oh right, if I keep killing monsters in the wild, especially creatures like dragons, is there a chance of dropping blueprints for structures like dragon's nest?"
After Mike asked this question, the system was silent for a while.
Then it replied.
[Sorry, the Castle Lord can explore this question on his own. The system has has no right to answer!]
"..."
Mike only felt that the system was messing with him again.
Could it be... that killing monsters in the wild could really drop a building blueprint like dragon's nest?
Mike changed his way of thinking and continued to ask.
"If the other Castle Lords find a construction blueprint for the dragon nest, can they build it?"
