Liu Hu didn't think too much and explained straightforwardly, "Because everyone's physical constitution is different. From birth to adulthood, it's generally a gradual increase. Also, various races have secret techniques to control bloodline purity and stabilize internal power. Take the Noel Clan, for example. Those who truly reach Level 42 bloodline are usually old folks from the Elders Council. Normally, common clan members are only granted strength up to Level 30. For those warriors in the arena, some of that restriction gets unlocked, so they might reach Level 35 to 40."
So that was how it worked.
Fang Heng listened and roughly understood.
This was similar to how he used dimensional energy to control the vampires.
Currently, his dimensional level was Level 39.
Ordinary vampires who hadn't fully unlocked their dimensional power could be controlled by Fang Heng at about Level 20.
