The issue of intelligence, referred to as the "intelligence barrier," is a real phenomenon on the Pangu Continent.
Generally, for a race to establish a feudal civilization, its intelligence must be at least around 90-100.
If their IQ is not above 100, even if they can excavate civilized relics, they will never be able to establish their own culture; at most, they can only form some primitive tribes.
For instance, after evaluation, the Mirage Cloud Dragon Big Golden has an intelligence of 95.
Even if there are ten thousand Mirage Cloud Dragons, they would still be unable to form a civilization because their intelligence isn't sufficient. More population would instead lead to internal strife.
To enter the Information Age, the intelligence of top talents must be above 140, and the average intelligence of the industrial population needs to reach 110-120; otherwise, they cannot develop a sound industrial system.
