Chapter 400: Return to Coral Island (Second Update)

As a Grand Duchy that started from the serf trade, besides the original followers, most of the civilians and the knights born from civilians in the Duchy of Sapphire actually originate from the serfs who were once plundered or purchased.

With generations living through it, these descendants of serfs have come to identify with the identity of the Duchy of Sapphire.

However, to continue to strengthen this sense of identification, the reigning Grand Dukes have refused to accept prisoners of war—the loyalty and identity recognition of captured knights are obstacles. Moreover, the lack of knights among the domestic nobles means that once the gates are opened, a large influx of prisoner knights would lead to a loss of national identity.

Without this sense of identification, a nation is no longer a nation; noble rebellions could occur at any time.
