永恒世界 is a Minecraft server whose website (mcyyy.com) hosts 御剑问道 and credits the game as 永恒世界出品 (made by 永恒世界). The game was announced on V2EX by the user wefgonujnopu, who says they built it with Opus 5.5 and had earlier written a Minecraft spider plugin. The site's ICP filing is registered in Sichuan, China.
A free 3D xianxia action RPG in the browser, in a blocky Minecraft-like style: fly on your sword through an endless wilderness and cut giants down at the nape. The developer says Opus 5.5 wrote the code, a little over 10,000 lines of three.js.
