Uncover the secrets of Remuria and complete the Canticles of Harmony questline without the grind!

The Sea of Bygone Eras is a newly unlocked part of Fontaine, directly connected to the Nostoi Region. Here you’ll explore the remnants of the ancient civilization of Remuria, solve intricate puzzles, and progress through the Canticles of Harmony world quest series. This area is packed with Hydroculi, hidden chests, domains, and mysteries waiting to be discovered — but reaching 100% completion manually takes dozens of hours.

With KingBoost’s exploration service, you can skip the grind and still enjoy every reward. Our team will fully complete the Sea of Bygone Eras, ensuring all collectibles, waypoints, and domains are unlocked. Along the way, you’ll gain primogems, mora, and Adventure Rank XP, all of which remain on your account.

KingBoost guarantees a seamless experience with flexible progression pace, secure piloted execution, universal account compatibility, and 24/7 customer support. You can also extend your order with extra options:

  • Chenyu Vale 100% Exploration — complete every puzzle, chest, and collectible in this iconic Liyue subregion.

  • 4.6 Story Quests Completion — finish the latest Archon and character quests introduced in version 4.6, unlocking new areas, rewards, and progression.
