An incomparably विशाल interstellar Metal City was actually nothing more than a fragment of a Civilization Supreme Treasure!
Liè Chǐ Demon Ancestor had only gradually realized this after clashing with the Source Energy Remnant Clan.
This was also thanks to the Evil Tide Civilization's extensive experience in waging war across the Star Realm. Even a "petty man" like Liè Chǐ Demon Ancestor had seen much of the world.
That was why, during the brief time it fought the Source Energy Sub-City, it had been able to make this judgment so quickly.
Had it been Dominators from other civilizations of the Star Realm, even after fighting the Source Energy Sub-City, they likely would not have been able to discern its true nature so swiftly.
Such an enormous Metal City was already a fragment of a Civilization Supreme Treasure.
It was hard to imagine what kind of might a complete Civilization Supreme Treasure would possess!
And just how many Source Energy Sub-Cities would make up that complete Civilization Supreme Treasure?
Such a colossal metal creation was beyond the imagination even of the Evil Tide Civilization, which had roamed across the Star Realm for over a hundred thousand years. They had never seen anything like it!
A Top-Level Civilization that had once participated in Dimensional Hegemony truly was extraordinary.
(PS: The Source Energy Sub-City was larger than the Wizard World's Space Fortresses, and its functions were more comprehensive as well.)
The reason Liè Chǐ Demon Ancestor had realized that the Source Energy Sub-City before it was a fragment of a Civilization Supreme Treasure was the milky-white beam that had shot out from within the Source Energy Sub-City during its earlier battle with Galaxy Star Safina.
The milky-white beam did not travel particularly fast, but once it locked directly onto Liè Chǐ Demon Ancestor,
