In the Immortal Cultivation World, judging the level of a Demon Beast actually has a very intuitive method.
That is to look at the body size!
First Order beings are about one zhang tall.
Second Order beings range from two or three zhang to seven or eight zhang.
But once they reach over ten zhang, they are basically at the level of a Third-Order Demon King.
As for Fourth Order Demon Emperors comparable to Human Clan Nascent Soul, their size is often over one hundred zhang, sitting or lying down like mountains, walking with the wind.
Hence the terrifying scene when a Great Demon travels, Demon Qi permeates, Devil Wind sweeps through.
The fact that Demon Beast realm is linked to body size has been deliberately studied by predecessors.
The conclusion has three points:
Firstly, large size intimidates similar kinds and occupies territory, which is a subconscious pursuit of all beasts for greater size.
