These were things that the dog-headed beastman told Zhou Yan out of kindness, seeing that he didn't understand anything.
Otherwise, Zhou Yan would find it difficult to stand his ground.
In the Immortal Domain, every aspect is rigorous, and the same goes for energy consumption which is severe. Despite being carried by the Soul Body and thus indestructible, if the consumption exceeds the balance, the realm will regress.
Therefore, in the Immortal Domain, it's not the older you are, the stronger you become; rather, the stronger the Soul Body, the more powerful you are.
And many ancient beings experience significant declines in realm and combat power.
Unless there is a unique energy replenishment, such as soul stone supplements, high-level medicinal herbs, elixirs, etc.
After understanding these, Zhou Yan then realized that the rules in the Immortal Domain are actually more detailed and more complete.
