This kind of method may seem quite normal but it was quite hard and painful process for a person in the 3rd grade and below to do this.
If one were to consider the normal outer disciple conditions who were 4th or even 3rd grade their cultivation speed would not even be half as good as Knaves.
There were three reasons for this, first as he had the spirit soul of the poison element he could reduce the time it requires to eat another pill after consuming the first.
This less to the second reason which is that he has a lot of cultivation resources thanks to his sister and now elder Fryer.
One has to know that the pills which he takes on almost a daily basis before we're only given ones a month to every other outer disciple.
If one wants to purchase the same pill the amount of spirit stones required would be ranging from 5 to 6 and even if they take a mission the rewards may not be above 30 to 40 stones.
This means that his one week of pill consumption may be beyond a normal outer disciples reward after two missions.
He was currently at the 4th shackle but it had only been about three months since he started cultivating, his speed of cultivation was not below someone with the heavenly root.
The third and the final reason is that he was given a cultivation manual that not only has a better foundation than the others but it is of higher tier as well.
If these all factors are put together than the current realm that he had reached was only obvious. If somebody else with the same situation but without the support of the cultivation manual or the pills would require a total of a year to reach these results.
From these, one could see how favourable Knave's current situation was in the Academy.
But even for him or any other person who has the heavenly root, it would take a lengthy period of refining the spirit energy for a year at least even with the help of high tier pills to breakthrough the shackled realm and enter the spirit refining realm.
If the same method is used by a person with the 4th grade or the 3rd-grade roots then the time increase exponentially.
A normal 4th-grade cultivator would require 3 years to breakthrough without any external help, while a grade 3 would require 5 to 6 years at least.
This is the reason why many cultivators go through dangerous missions so that they can have enough contribution points from the Academy so that in the future they can apply for the second method of the breakthrough from the shackled realm.
The second method of the breakthrough is to use an external force to help break the shackle around the dantain and step into the spirit refining.
As the name of the pill describes itself it does the job of breaking the shackle on the dantain in the considerably stable manner.
As the main difficulty or obstacle a person faces is that after breaking through any realm or even stage is that whether his foundation is stable or not.
If there is even a tiny problem in the foundation after the breakthrough it is best for the cultivator to work on it or use any method possible to cement his foundation.
Because as long as even a tiny crack remains in the foundation it would later cause the foundation to slowly destabilize and cause the spirit energy to run amock leading to demonic heart which will indirectly kill the cultivator.
Seeing such, the pill created not only helps in breaking through the realm but also helps in building a strong foundation but as one might know that nothing in this world is simple as it seems.
