The Torrential Flood Dragon had no knight, and such a state had persisted for centuries; its original knight was also a member of the Lieyang Royal Family.
But now, with innumerably many branches of the Lieyang Royal Family and the contract's power having not been reinforced in hundreds of years, the bond of the contract had effectively become null and void.
It wouldn't be surprising for the Torrential Flood Dragon to take interest in any knight and form a contract with them.
The current decision-maker of the Scorching Torrent Kingdom is King Ares.
If the Torrential Flood Dragon wanted to choose a knight, it would certainly need King Ares' approval—of course, if the Torrential Flood Dragon truly fancied a knight from another race, King Ares would not directly oppose it but would find a way to assimilate the knight from the other race.
