In the Genshin Impact Natlan Archon Quest Chapter V: Act IV – The Rainbow Destined to Burn, you must enter a quest domain called "Remnants of the Secret Source" to stop Capitano's Ley Line reconstruction plan. Deep within the domain, you must solve a puzzle that involves rotating three mechanisms.
Remnants of the Secret Source Genshin Impact
To solve the puzzle, you must rotate three devices until the wheels successfully form the restored image of a dragon. Interacting with a mechanism will activate the wheel, and it will continue to rotate until you click Stop.
The first mechanism will rotate a C-shaped segment inside the wheel. Activate it and wait for the wheel to rotate until the shape is positioned as shown in the image above: the closed end of the C-shape should be facing northwest. Once it is in position, interact with the mechanism again to stop it. The segment should glow briefly to indicate that this part of the puzzle has been successfully completed. If it does not glow, try adjusting the wheel again.
Transform into a Yumkasaurus and use its ability to go to the upper platform, where the arrow is pointing. You will find the second mechanism.
