Ekter was unsure, yet he was not willing to fall into a trap over such a trifle, especially since Gu Shanhai's appearance made him somewhat puzzled by Merlin's true intentions.
"I hope Sir Ekter can keep his word. I am merely an ordinary Druid, while Sir Ekter comes from a noble family—an individual in exchange for a clan. I believe Sir Ekter knows how to choose," Gu Shanhai's meaning was clear: his death would mean only the loss of a lone man, but his entire family, including his descendants, would suffer from the curse. No matter how one thought about it, Ekter would be at a disadvantage.
Ekter didn't take Gu Shanhai's threat too seriously, since betraying Gu Shanhai had never crossed his mind.
If what Gu Shanhai said was true, then wouldn't he have been duped by Merlin, the wizard? At that point, wouldn't he be in an awkward position with both sides?
After their talk, Ekter left in a hurry.
