Lost Energy Block is an item that can be found in various spots in Genshin Impact. All of them are located in Devantaka Mountain, where a giant Ruin Guard resides. If players follow the Vimana Agama questline, they’ll eventually find themselves inside the giant robot, attempting to fire it up using the backup power source. To do this, people need to do a bunch of tasks, like connecting all four Relays in the middle.

Considering the ruins, it’s no surprise that a lot of damaged Ruin Guards scatter around the area. After fulfilling a small condition, people will have the option to Load these robots, and in exchange, Travelers will get a code for more lore analysis. To get all the secret codes, players must first find all the Lost Energy Block locations in Genshin Impact.
