He realized that they were like salt dissolved into water and in order to be able to remove the salt from the water was essentially impossible unless you take each particle of salt that was hidden among the water molecules and remove it.
So the idea he came up with was that in order for a human being to "become aware of the five hindrances" they essentially have to be aware that their soul was completely contaminated by them.
Therefore to make sure he was right he started checking his soul to see if his theory was correct, he first started analyzing his very soul deeper and deeper until he could see each and every whisp of the so-called spirit energy.
However, what he saw shocked him, even though his soul looked pure at first glance when he finally saw each individual whisp of the spirit energy he saw that each and every one of them was in fact covered in a strange black liquid, that gave off a specific feeling.
When he saw that his first thought was to immediately remove it, but he was completely stumped as to how he could do so. However, the Heavenly Will once again assisted him.
It told him that how he should remove it was that he should manipulate the whisps of spirit energy and use them as his hands to remove the black liquid off of the other whisps of spirit energy.
He tried doing that but at first, it was very difficult to even move one whisp of spirit energy let alone multiple but through repeated practice, he was able to move the spirit energy as if it was his limb.
Then he picked a whisp of spirit energy at random it was then surrounded by other whisps which he used to separate the black sludge from the lone whisp.
However, once he tried separating it he felt as if his very soul was being repeatedly stabbed, but he was a Buddhist monk who has trained his will in his previous life so he persevered, and finally, after an unknown amount of time he finally succeeded in removing it.
And what followed was that that whisp of spirit energy, after being separated from the black liquid, started glowing golden and Wang Wei felt as if his entire body and spirit were cheering.
Moreover, he suddenly felt as if he was one with the entire world, his senses expanded outwards and he could sense everything within a one-kilometer radius, he could even see Qi for the first time ever. He realized that this was the spiritual sense that cultivators developed at the Golden-Core realm.
Nonetheless, he still wasn't done so he temporarily put aside his newfound ability and continued the process. But when he tried to remove the black sludge from his soul entirely there was a strange attraction force as if there was a magnet that didn't allow it to leave.
Wang Wei knew that that meant that this was only a part of a single hindrance and if he wanted to remove it he first had to cleanse his entire soul of that particular hindrance to remove the attractive force between them.
Therefore he immediately got to work cleansing the other whisps of spirit energy, but he immediately noticed that each whisp of spirit energy gave off a different feeling.
This meant that the different black liquids that contaminated them weren't uniform and were divided into different types, some gave off a feeling of anxiousness others gave off a feeling of lust.
Once he felt the feelings contained within the black liquid he removed from the first whisp he realized that it radiated feelings of hunger.
That meant that this particular black liquid was a part of the first hindrance and particularly it what it represented was, in fact, the sensory desire of taste.
So in order to not waste time he located the other whisps that contained the first hindrance and started cleansing them first.
However, an interesting phenomenon occurred, as he cleansed another wisp of spirit energy the removed black liquid as if it was sentient immediately merged with the other black liquid as they continued to float in his soul.
As the process continued, instead of using the contaminated whisps he started using the cleansed golden ones and he came to a realization that the control he had over the golden wisps of spirit energy couldn't even be compared to the contaminated ones.
Therefore the more wisps spirit energy he cleansed the faster the process went, and an unknown time later he finally finished cleansing the entire first hindrance.
However what he wasn't expecting was after the last part of the hindrance was cleansed and the remaining blobs of black liquid merged together, it immediately solidified into a glossy black sphere while a huge repulsion force was also created between it and his soul.
And before he could react it left his soul and floated in the black space that his soul resided inside of.
What was completely out of his expectation was for the Heavenly Will's voice to suddenly come and tell him to prepare himself, and what followed next was that the solidified black sphere broke open and from it, something that looked similar to his own soul emerged.
Except that while his own soul started taking on a golden color after he cleansed it of the first hindrance.
The thing that emerged from the black sphere only looked like him, everything else was completely different, it was made out of the black liquid and by looking at it you would feel as if it was the filthiest thing you have ever seen.
Even being near it would make a person sick to their very core, and even Wang Wei who was actively suppressing his emotions felt that his control over them slipping.
That was extremely strange as Wang Wei has trained his whole life to control his emotions but even one look at this disgusting thing was enough to almost make him lose control over them, let alone a normal person.
