Watching the Kaidan Fire on Liao Yunhuai's body, Feng Xue couldn't help but show a puzzled expression.
Because any kaidan he had seen before, with humans as the vessel, essentially did not have a Kaidan Fire.
[Yan Country people all practice Martial Arts] and [Libra] are collective kaidans that can grant humans power, but in reality, they are similar to the relationship between a nuclear power plant and an appliance. Feng Xue himself was akin to this "nuclear power plant," converting nuclear fuel ([Identity]) into nuclear energy (Kaidan Fire), and then generating electricity (Power) from it. The Yan Country people, as "appliances," essentially did not possess the ability to utilize nuclear energy (Kaidan Fire). They enjoyed the already converted electrical energy (Power).
