The nine Qi Induction Pills that Jiang Yun refined were at least Human Rank, and after being placed in water and taken out, five of them changed in grade.
Three Human Rank pills became Earth Rank, one Earth Rank pill became Heaven Rank, and although the other Heaven Rank pill remained Heaven Rank, its medicinal effect reached its peak, containing no Impurities whatsoever, making it perfect.
After carefully pondering this situation for a long time, Jiang Yun came to a conclusion: "This is like Cultivation. The medicinal effect of a Medicinal Pill is like the Spiritual Qi in the human body. When there is enough Spiritual Qi, one can enter the next Realm. When the medicinal effect increases to a certain extent, it will also Breakthrough to the next Rank. It's just that no matter how much the medicinal effect increases, it cannot change the inherent grade of the Medicinal Pill."
"The so-called Heaven, Earth, Human, and Mortal four Ranks are just a general classification standard and cannot specifically indicate how much medicinal effect each Rank of Medicinal Pill possesses."
"Therefore, the four Qi Induction Pills that did not change in grade, including those Medicinal Pills Elder Sha gave me before, originally contained much less medicinal effect. Even if it increased threefold, it still wouldn't reach the standard for advancement."
Aside from the Medicinal Pills being able to advance, what surprised Jiang Yun the most was that Spirit Stones could also be placed in the water. After being branded with that strange mark, although the amount of Dao Intent contained within them would not change, the amount of Spiritual Qi would also increase threefold, and it would become even purer.
"Although I don't have a second-grade Spirit Stone to compare with, it's not difficult to infer that if the Spiritual Qi in a Spirit Stone increases to its maximum, it should, like Medicinal Pills, also be able to raise its grade, making the Spirit Stone change from first-grade to second-grade."
Finally, Jiang Yun successively placed the three Meridian Opening Pills into the water formed by the stone, and the result made him very satisfied.
All three Meridian Opening Pills reached Heaven Rank, and one of them even reached the ultimate perfection.
"Swallowing these three Meridian Opening Pills, even if I don't reach the Nine Levels of Vein Opening! Realm, opening the eighth Meridian should be no problem."
Driven by the desire to quickly strengthen himself, Jiang Yun unhesitatingly put all three Meridian Opening Pills into his mouth and swallowed them, beginning to continue opening his eighth Meridian.
However, Jiang Yun still underestimated the medicinal effect of these three Heaven Rank Meridian Opening Pills!
Meridian Opening Pills are not Qi Induction Pills; they do not draw Heaven and Earth Spiritual Qi to open Meridiens. Instead, they contain Spiritual Qi from plants and maximize it as much as possible.
Most Cultivators take Meridian Opening Pills of Earth, Human, or Mortal Rank, and even so, they only take one at most when doing so.
As for Heaven Rank Meridian Opening Pills, the Spiritual Qi contained within them is simply too vast. If the Meridiens can withstand it, then one pill is enough to open one Meridian, even the ninth!
Of course, some Cultivators have taken Heaven Rank Meridian Opening Pills, but when taking them, there must be at least a Blessed Land Realm Cultivator acting as a Protector nearby. The purpose is to carefully guide, and even store, the Spiritual Qi transformed from the Meridian Opening Pill, dividing it into several doses to open the Meridiens.
Otherwise, the Spiritual Qi transformed from a Heaven Rank Meridian Opening Pill will have a very high chance of directly tearing the Meridiens, or even bursting the Cultivator's body.
Jiang Yun had no idea about this, and Old Hei also thought that since Jiang Yun was an Alchemist, he would surely know the taboos of taking Meridian Opening Pills, so he didn't specifically explain it.
Therefore, when Jiang Yun took three Heaven Rank Meridian Opening Pills at once, not to mention one of them was perfect, this act was tantamount to suicide, and the most tragic form of suicide at that.
The Impurities in Jiang Yun's Meridiens were already extremely tiny, and the eighth Meridian had already been opened by a third. Therefore, when the three Meridian Opening Pills entered his mouth, the vast Spiritual Qi they transformed into was like an endless, surging torrent, carrying destructive power, instantly flushing open the eighth Meridian completely.
Although he entered the Tongmai Realm eighth Realm, Jiang Yun had no time to be happy. Especially when he saw the vast Spiritual Qi in his body that had barely diminished, he finally realized his underestimation of Meridian Opening Pills and hurriedly tried his best to guide this Spiritual Qi towards the ninth Meridian.
The Nine Levels of Vein Opening!, as the last Realm of the Tongmai Realm for most Cultivators, naturally had the greatest difficulty in Breakthrough. The method of opening it was also a gradual process, slowly and steadily connecting it.
Even though the Impurities in Jiang Yun's ninth Meridian had all been shattered into tiny states by Jiang Wanli using various medicinal powers, the Spiritual Qi torrent could not instantly flush out all the Impurities in a short time. This led to a large amount of Spiritual Qi accumulating temporarily in this Meridian.
Although Jiang Yun's Meridiens were much thicker than others, due to the sheer volume of Spiritual Qi, this Meridian simply could not accommodate so much Spiritual Qi and immediately began to swell rapidly.
Jiang Yun hurriedly began to move the excess Spiritual Qi out of his Meridiens, intending to release it through the pores and seven orifices on his body.
However, the vast Spiritual Qi also emitted immense pressure, blocking his seven orifices and pores, making his body completely sealed, and the Spiritual Qi simply could not escape.
However, this was not the worst part!
Just as cold sweat began to seep from Jiang Yun's forehead, a violent roar suddenly echoed within his body.
"Boom, boom, boom!"
The Spiritual Qi torrent was blocked by Impurities in Jiang Yun's ninth Meridian and could not find an outlet in his body, causing it to gradually become violent.
The Spiritual Qi torrent actually began to repeatedly charge towards those Impurities. The continuous impacts produced violent roars that vibrated Jiang Yun's entire body.
Gradually, Jiang Yun's Qi and blood churned, and even blood began to flow from the corners of his mouth. Yet, the ninth Meridian was only half-opened, but the Spiritual Qi torrent had at most decreased by only a third compared to before.
If this trend continued, Jiang Yun's body would be directly burst by this Spiritual Qi before the ninth Meridian was even opened.
Thoughts raced through Jiang Yun's mind: "No, I must quickly find an outlet to release the excess Spiritual Qi, otherwise, before the Meridiens are opened, I'll be literally smashed to death by this Spiritual Qi."
Thinking of this, Jiang Yun strenuously raised his hand and suddenly pointed a fierce finger at his abdomen.
With this finger, Jiang Yun used almost all his strength, forcefully poking a hole in his abdomen.
This was Jiang Yun's idea: since the Spiritual Qi could not be released and his pores and seven orifices were blocked, perhaps opening a wound on his body could allow this Spiritual Qi to gush out.
However, Jiang Yun quickly discovered that from the wound on his abdomen, which almost pierced through his body, let alone Spiritual Qi, not even a trace of blood flowed out.
Clearly, the immense pressure generated by the Spiritual Qi torrent had again blocked this wound.
"This method won't work. How can this Spiritual Qi be released after all?"
Just as Jiang Yun was troubled about how to find an outlet, a cold voice suddenly rumbled like muffled thunder above his head: "Jiang Yun, get out here!"
