Wang Wei continued telling them "I must have forgotten to explain to you, as such common knowledge is very common in the heavens, but the cultivation at the Blood-Exchange realm is only the end of Body Refinement that prepares you for the start of real cultivation!".
"The people that are at this realm can only live until a thousand years old and even the most common people in the heavens are at this realm, as a matter of fact, Body Refinement isn't even considered to have begun on the path of cultivation!" once everyone heard that they were stupefied, that the most prestigious people in their society would only be common people in the heavens.
And so-called Immortal Protectors were mortified at the prospect of their death after thinking that they were immortal for so long.
Wang Wei was of course lying, the reasons he did so were twofold. First of all, he needed a believable background story, and the second was that he didn't want them to fail the mental demon tribulation.
After all to pass the tribulation one has to incredible will and one way he thought of to make someone increase their will and endurance was making them endure the torture that is physical cultivation.
Therefore once someone reached the peak of so-called Body Refinement, they would both have enough time, considering their long lifespan, to sense their soul and learn Buddhist text.
But also enough will to survive the mental demon tribulation, and the pain that cleansing your soul causes, so in order to protect them, he told them they need to first complete Body Refinement to continue into Buddhist cultivation.
"However once the Heavens sent me to protect your tribe, the Body Refinement realm was all that I was allowed to share with you. However, the Heavens were pleased with how your civilization has progressed, therefore I was sent back down here to guide your civilization into taking the next step in your development and sharing with you the next realm of cultivation!" as Wang Wei finished the sentence, the Immortal Protectors that have fallen into the pits of despair due to his first sentence had their hopes once again reignited.
"You will bring everyone that has entered the Body Refinement realm in front of my temple in three days. There I will preach about cultivation and the teachings of Heaven!" Wang Wei said directly to Huang Xue.
"Yes, I will follow the commands of the diety! Would the diety like to rest in the palace while he waits?" Huang Xue replied as he bowed.
Wang Wei then just simply nodded as Huang Xue started leading him to his room, of course, Huang Xue didn't dare give him an inferior room and even lead him to his own Imperial Chambers, where he slept.
Wang Wei was aware of that therefore as a token of goodwill he waved his hand and with a slight movement of his thoughts, the Qi of the surroundings started rushing into the body of Huang Xue.
And once it reached a certain saturation, the very marrow of his bones started to crack and in just a few moments it has improved enough for him to officially enter the Blood-Exchange realm.
This was a technique the tutors his father hired used to help him cultivate and break through. It was also one of the reasons his cultivation speed was so rapid.
However, in the Celestial Wang realm, the help one can get from doing that is minimal as the palace of the Wang family had an enormous amount of Qi-Gathering formations and the Qi was already very close to the maximum possible concentration.
But here where there are no such things as Qi-Gathering formations the help someone who can control Qi could provide during Body Refinement is enormous.
Once he felt the changes in his body Huang Xue was shocked, he couldn't believe that a simple wave of Wang Wei's hand could make him break through.
In fact, he was so shocked that he didn't even dare look Wang Wei in the eyes as he bowed and slowly left the room.
Wang Wei already expected that reaction, so the only thing he did after Huang Xue left was to sit in the lotus position on the bed in deep meditation and wait for three days to pass.
However that didn't mean that he just had to wait, he immediately entered the black space where his soul was located, which he started to call his soul space, and started observing the condition of his soul.
His soul looked very peculiar after he cleansed it of the first hindrance, it looked like a blue sea with golden fireflies within. In some weird way, he may have found it looked beautiful, but he truly couldn't see it as anything other than filthy knowing what he knows.
So without waiting anymore, he started the process of cleansing his soul even further, he started focusing on the second hindrance, so-called Hatred or ill-will. Then he located every single whisp that was contaminated with it and started the process.
Except for this time as soon as he started he felt the other remaining hindrances within his body start to get uncomfortable. As he realized previously they had some degree of sentience and they obviously figured out what the process meant, it meant them getting eradicated.
However individually they were very weak and couldn't do much except inflict pain upon his soul. That's when he understood that each time he cleansed his soul of a hindrance it would get much harder and more painful to cleanse the next one as they got more and more desperate to live.
This new information made him even more confident in his decision to make the people of the empire have to complete physical cultivation first in order to start Buddhist cultivation.
