The brilliant Magic Crystal Technology once made the Purple Crystal Cosmic Civilization become another Cosmic-level Civilization in this universe after the Holy Mark Civilization.
However, the difficulty of learning Magic Crystal Technology increases geometrically.
The further you go, the harder it becomes to learn and master.
At the height of the Purple Crystal Civilization, they were in a state of invincibility.
This led many citizens of the Purple Crystal Civilization to not strive to delve deeply into Magic Crystal Technology.
Even when the Purple Crystal Civilization declined from its peak, it remained a cosmic overlord.
Even the then incredibly powerful Divine Race did not have the ability to challenge the Purple Crystal Civilization.
When they sealed off the Purple Crystal Star Realm to enjoy peace, even fewer people were willing to work hard on Magic Crystal Technology.
