"Promotion Conditions": The strongest attack energy range exceeds 300,000, and have three Civilization Wonders, with a territory span reaching one billion light years.
"ps: Every upgrade from Second-level Civilization, including every subsequent promotion, will release a 'Promotion Ripple' detectable by all surrounding civilizations. The higher the level, the wider the range of the 'Promotion Ripple'.
"Civilized Means": Within the civilization's territory, Murphy Stone Ore will come into existence.

The methods of a Level 6 Civilization are extremely simple.
Help civilization acquire more Murphy Stone.
In theory.
The larger the territory range, the more Murphy Stone Ore is created.
For example...
If the "Nia Star System" was within the territory range of the Cyan Mountain Civilization, then there would be a chance for Murphy Stone Ore to be created within it, but if not, then there would be no such chance.
A fairly simple civilized means.
