In general, a race's "Sequence Ecological Nest" is the most expensive and most valuable core treasure of that race.
It is also the foundation of the inheritance of a race's Sequence Civilization strength.
Just like the Steam Ecology of the [Steam Wizard] Sequence Tree that Tuck now constructed in the human world.
It can basically be considered a priceless treasure.
But to this tiny Mechanical Race with only a handful of Mechanical Masters and not even a legendary mechanical powerhouse,
the phrase "race's most expensive treasure" is nothing more than a fig leaf for the continuation of the race's fire-kind.
It's nowhere near as substantial as a piece of Legendary Chaos Treasured Metal material.
After the projection finished communicating and trading with several Mechanical Masters in the Black Domain Wasteland,
within the Four-Tusked Elephant World Ship, Tuck slowly gathered his thoughts.
"Wendy!"
