Genshin Impact, is there a main line after Raytheon?

After Genshin Impact finished playing Raytheon, there was a main line, which was launched in version 2.6, requiring players to enter the underground rocks in Li Yue.

In terms of game content, the 2.6-open layered rock cave has two maps, above-ground and underground, which is longer and more time-consuming than the 2.5-time-limited map "Three Boundaries Road Sacrifice". The protagonist will enter the layered rock, explore the "secret of the disappearance of the ball man" and welcome the return of Dynesrab in the main line. The next step (that is, version 2.7/2.8) is left to sumeru.

What's New in Version 2.6

2.6 Two sacred books have been added: Zhusha's past life record and aftertaste, of which the latter is "after-sales service" after a lapse of 13 months. In terms of activities, version 2.6 uses the roles of rice wife sacrifice and Cai Hua +Mond in Dongting instead of the Wind Flower Festival originally arranged in Mond, and other activities, such as photo taking activities, organ chess tan 3.0, knife shaking activities, flower arrangement/cooking, etc.
