"While it is special that each of the trio were powerful. The Evil Law cannot reproduce laws. So when all evil comes together, a single Evil Law can be obtained.
As for Pure Law, she can create laws based on the purest mindsets. So for instance, you want a Law to protect your city. Your motivation for it is pure but other people may not have that same pure mindset. The Law could protect just the single city. Increase that by let us say 20 cities, a Kingdom could get the Law of Protection as long as everyone remains pure.
Eventually that kingdom would collapse. Another Kingdom wishes for that Law, that Law could change the name of the Kingdom it is replacing. The situation for a city is the same."
The boy and girl stopped looking at Rex who seemed to be in a pleasant mood currently.
"How can we change the Law for the True Saint Law?" Rex asked politely.
If he had to, he would venture back into the past and change the average person's mindset on what must be sacrificed.
"Truthfully, that Law has been in stone. Whereas normal laws are vocal and paper written. That was completely wrote on stone and accepted by a lot of people. The only true way to change it is to either destroy it, which means killing me." The boy spoke sadly, "Or the Law was never put into place." The girl replied trying to cheer up her Bubba.
"Either way we are destroying the boy." Rex thought.
Rex patted the head of the boy. Sadness flowed from the boy and Rex knew how hard it was for him to casually speak about his death.
"What if we forced a change in the past while you are there?" Rex asked.
"Huh?" All three spoke in confusion.
"By changing you in the past, while maintaining what is you in the current. We could make that Law better for me. Which would ultimately make our life better by not having human sacrifice inside of you."
The trio were wondering if Rex was just plain stupid or a miracle genius.
"We could ask Momma Law but that would be on her if you could change me back then." The boy replied.
"Call her tomorrow and we can continue learning."
The duo decided to speak more about how a Law is formed and how each person affecting it causes it to change. By nighttime, the entire group was already passed out from the overload of information.
Rex pictured himself back in time when the Law was being created. How he would successfully change the Law he could change it to be material sacrifice instead of human or even a random person who has no connection to him.
While his intention is pure, his mindset is not pure for that. The Pure Law already knowing what he wants to do decided to allow him to see what actually happened.
Rex began to dream. This dream the Pure Law was looking sad. She knew how much force it takes to sacrifice a person either willing or not.
"Please watch as the Law you would change affect the Nine Realms."
Rex watched as people saw that the material sacrifice would be the greatest amount of Qi Stones and armor would be sacrificed and still not enough.
People would cruelly curse that Law for being in existence. It might be active now but it is not being cursed or neglected. It just takes a special someone to activate that Law.
Rex was how that his purity would cause so much pain and suffering for not only the blacksmiths but everyone. People now would be ruthless and slaughter a baby for only enjoyment.
As he watched more down the line. It became worst and worst until the Nine Realms destroyed themselves. Rex was devastated. Nothing could change the fact that the Law that he hates and wants to change would be so destructive when changed.
As he pondered about what to do. The Pure Law asked a single question, "Do you want the title of True Saint?"
"No." Rex immediately replied.
Pure Law removed Rex from being able to obtain the True Saint title.
"Do you wish to obtain the Saint title?"
Rex pondered about it. "What is the difference?"
Rex watched her lips and he did not want that title either.
The boy cried during the night from having Rex ripped from him.
"I will achieve what most people fail to do. I will obtain a Saint Title my way. My path through the Nine Realms has been different for some odd reason and I will not allow others to become part of that reason why. I thank you for being generous.
I want that boy to be healed and ready to seek a new friend and not just a person who will allow his or her husband or wife or Soul Mate to perish because of his Law. I have learned that the purest of Laws does indeed need human sacrifice.
I do not want human sacrifice. I would rather use my entire Life Force to completely wipe out everything but my wives and Soul Mate. With the destruction of the Nine Realms at my hands, I cannot live that way. So do you believe that my intentions are pure and my mindset right?"
A frown and nod of agreement made Rex forge his way to become a Saint. This would not only change him but the entire Nine Realms.
