He had no choice because he, ultimately, was of flawed lineage.
Yet, he had to do it.
Presenting the "Book of Covenant" before all the attending nobles and the populace was part of his and Duke Conte's plan!
Although his own blood was inadequate, he now possessed the blood of Count Castel.
With the bloodline of Count Castel, a direct descendant of the Romany, activating the Book of Covenant should be no issue.
Once he utilized Castel's fresh blood to activate the Book of Covenant, he'd have the opportunity to resubscribe to the Roman Sword's covenant!
As for whether the Roman Sword would recognize his lineage or perceive his cheating…
That was not an issue.
For he too possessed Roman blood.
Even though it was impure, and even if he used Count Castel's blood, the Roman Sword didn't care.
The reason was simple; the Book of Covenant was just a key left by Romannus and didn't significantly concern the Divine Artifact.
