It's important to know that they spent a long time researching the Centipede Formation. Many experts worked together for several years until they accidentally discovered that different attributes of True Qi can be integrated, greatly enhancing the power.
The more integrated attribute True Qi, the greater the power.
Thus, the Centipede Formation they created is truly unprecedented, with terrifying power.
Actually, it's not that ancient people weren't clever enough to come up with this method.
However, in remote antiquity, such conditions didn't exist.
Many intelligent races could only develop cultivation techniques with a single attribute.
But today, because the Earth once nurtured many intelligent races, they left behind their legacies.
The attributes of the cultivation techniques were different.
Humans now have access to many of these legacies, cultivating True Qi of various attributes.
Thus, there was a foundation for the Centipede Great Formation.
