Now that there is no great Taoist master around me who can tell me these Taoist knowledge, and I happen to have the conditions, I might as well explore and verify it.
Yuanxiao is now at the first level of Qi Refining. Next, he must follow the first level of Qi Refining exercises, constantly absorbing spiritual energy, and using spiritual energy to continuously flush the meridians and acupuncture points, thereby stimulating and strengthening the physical body.
Then he will start to nourish the spirit and soul. When the spirit and soul grow to a certain extent and can leave the physical body, he will have entered the second level of Qi Refining.
The soul is also called the spiritual consciousness. Being able to project the spiritual consciousness is a sign of entering the second level of Qi Refining.
Yuanxiao held the small middle-grade spirit stone tightly in his hand. At the same time, he took out dozens of lower-grade spirit stones and placed them in front of him for use, and began his second practice.
Looking at the entire Song Kingdom's immortal cultivation world, there may not be another person who can use middle-grade spirit stones to cultivate at the first level of Qi Refining in the past hundred years.
Not to mention other inner disciples, even the foundation-building elders of Yunhai Sect still don't have middle-grade spirit stones to use. It's not that they can't use them, but that they can't afford them.
As soon as Yuan Xiao started to activate the spiritual energy, he felt an extremely strong spiritual energy coming from his palm, like a flood that had been opened, flowing through his body in an instant, and he couldn't help but tremble all over.
If the spiritual energy flow of the previous low-grade spiritual stone was a stream, then the spiritual energy flow of the medium-grade spiritual stone was a river. If the spiritual energy flow of the previous low-grade spiritual stone was simple food, then the spiritual energy flow of the medium-grade spiritual stone was delicacies from the mountains and the sea.
The spiritual energy provided by the medium-grade spiritual stone not only increased significantly in quantity, but also increased several times in speed, and the quality was far superior to that of the low-grade spiritual stone.
Especially when cultivators are attacking barriers and breaking through bottlenecks, high-quality spiritual stones are a strong boost, instantly providing a large amount of spiritual energy to ensure that cultivators are not forced to stop practicing due to lack of spiritual energy.
Moreover, because the spiritual energy is of higher quality, if the bottleneck can be broken, the foundation laid is often more solid than others and has stronger plasticity. Therefore, when high-level cultivators are in seclusion to attack the next level, they are in urgent need of high-quality spiritual stones.
As the first person to pass the test of the spiritual energy absorption speed that once exceeded ten stars, Yuan Xiao's spiritual energy absorption speed was terrifying. In addition, the speed at which the middle-grade spiritual stone provided spiritual energy was several times faster than that of the lower-grade spiritual stone.
After half an incense stick, the large amount of spiritual energy contained in this small piece of middle-grade spiritual stone was completely absorbed, gradually showing a grayish white color, and finally shattered in the palm of his hand. Yuan Xiao already had a rough estimate of the spiritual energy content of this small piece of middle-grade spiritual stone.
Yuanxiao immediately picked up the low-grade spirit stone in front of him and continued to practice, and began to pay close attention to the number of low-grade spirit stones he consumed and the amount of spiritual energy he absorbed.
One piece, two pieces...
Yuanxiao did not stop practicing until the fifth low-grade spirit stone shattered. He looked at the spirit stone fragments in front of him and began to estimate.
A medium-grade spirit stone that is only one-tenth the size of a normal spirit stone, in terms of the spiritual energy contained in it, is roughly equivalent to 5 low-grade spirit stones. In other words, if it is a complete medium-grade spirit stone, its spiritual energy content is roughly equivalent to 50 low-grade spirit stones.
But in addition to the perspective of spiritual energy content, we must also consider the characteristics of mid-grade spiritual stones, such as the fast speed of providing spiritual energy, high quality, and many benefits for cultivation.
In the world of cultivation, the exchange rate of mid-grade spiritual stones to low-grade spiritual stones on the market should actually be higher.
It is true that true knowledge comes from experiments, and only with practice can one have the right to speak. Although the actual situation is not exactly the same as Yuanxiao's estimate, it is not far off.
In fact, the exchange rate of spiritual stones in the world of immortal cultivation is 100 low-grade spiritual stones for one medium-grade spiritual stone, 100 medium-grade spiritual stones for one high-grade spiritual stone, and 100 high-grade spiritual stones for one ultimate spiritual stone.
In fact, at the level of ultimate spiritual stones, the ultimate spiritual stones themselves are also treasures. The holders usually carefully collect them or keep them for their own use at critical moments, or directly exchange them with other immortal cultivators.
Basically, they will not exchange ultimate spiritual stones for lower-grade upper-grade spiritual stones.
