The Count looked interested in the deal. After all, he would be able to get the resources for his experiment. And considering the one offering this deal was the Supreme Devil Organization, they would most likely try to hide their relationship with him.
After all, it wouldn't be good if he was crushed by the Royal Family because of the allegation.
So, the secret should be leaked anywhere.
However, he was still concerned that the Supreme Devil Organization pulled this trick in order to make the Royal Family crush him. That way, the kingdom would just get weakened.
Even if his research was somehow dangerous, it didn't change the fact that losing a Count wasn't something that could be brushed away easily.
So, the Count tried to think with the little time he had.
