Low Grade, Medium Grade, High Grade, and Top-Grade; these are the four grades of Spirit Stones.
As for why the Spirit Stones he enhanced were only Medium Grade and not Top-Grade, He Pingsheng didn't understand.
He decided to keep reading to find out the uses of these Spirit Stones.
He buried himself in the text once more.
After about half an incense stick's time, He Pingsheng looked up in shock.
He finally understood why his gathering treasure basin hadn't enhanced Top-Grade Spirit Stones.
Because they were too Heaven-Defying.
Ordinary Low-Grade Spirit Stones could be used as currency and tools for transactions within the Cultivation World.
Medium Grade Spirit Stones, however, contained abundant Spiritual Qi; even a single one could support the cultivation of a Qi Refinement Stage or even a Foundation Establishment Stage Disciple.
It was well-known that Cultivators in the Cultivation World needed to seek out places rich in Spiritual Qi to cultivate.
Where was Spiritual Qi abundant?
The answer was: Blessed Lands, famous islands, and immortal mountains.
For example, the Tai Xu Sect was established here precisely because there was a Spiritual Vein exposed in the mountains beneath the Tai Xu Sect, which could continuously emit Spiritual Qi for Cultivators to absorb and cultivate.
Once outside the Tai Xu Sect, there would be no Spiritual Qi, making cultivation impossible.
But if one possessed a Medium Grade Spirit Stone, they could cultivate even in an ordinary place.
This was because a Medium Grade Spirit Stone contained abundant Spiritual Qi for one person's cultivation, even more concentrated than the Spiritual Qi provided by lower-grade Spiritual Veins.
And this was only a Medium Grade Spirit Stone.
What about High Grade?
High Grade was even more extraordinary.
If a High-Grade Spirit Stone was buried underground, it would become a small Spiritual Vein.
To put it this way, a single High-Grade Spirit Stone was enough to support a Cultivation Family.
As for Top-Grade Spirit Stones, they were even more Heaven-Defying.
A Top-Grade Spirit Stone the size of a human head, when buried underground, was equivalent to a medium-sized Spiritual Vein, already capable of supporting a large Sect like the Tai Xu Sect.
Therefore, He Pingsheng finally understood why the gathering treasure basin only enhanced Medium Grade Spirit Stones.
What if it had directly enhanced Top-Grade Spirit Stones?
Of course, what He Pingsheng didn't know was that the gathering treasure basin could indeed enhance Top-Grade Spirit Stones, but this enhancement ability was related to his cultivation and the degree to which the gathering treasure basin had been refined; it might not be possible now, but that didn't mean it wouldn't be possible in the future.
Besides this, there was also an exchange rate between the different grades of Spirit Stones.
For example, one Medium Grade Spirit Stone could be exchanged for ten thousand Low-Grade Spirit Stones.
One High-Grade Spirit Stone, in turn, could be exchanged for ten thousand Medium Grade Spirit Stones.
As for the value of Top-Grade, these cultivation notes didn't mention it, but it was certainly even more Heaven-Defying.
“Ten thousand…” He Pingsheng was immediately speechless.
He currently had twenty thousand Low-Grade Spirit Stones in his possession.
However… they were useless.
Although he had Medium Grade, He Pingsheng wouldn't be foolish enough to actually use Medium Grade Spirit Stones for consumption.
Before possessing sufficient strength, displaying items that didn't match one's status would only invite disaster.
“Hmph…” Looking at the remaining approximately three hundred Spirit Stones, He Pingsheng let out a soft sigh: “I still don't know when I'll gather enough Spirit Stones to buy a Storage Pouch!”
“No rush… I'll take my time!”
First, he threw the Low Grade Magical Artifact, the Flying Sword, into the gathering treasure basin, then pushed the gathering treasure basin under the bed.
He would enhance them one by one!
While enhancing, He Pingsheng wasn't idle.
He took out his Pill Furnace and began Alchemy.
Master Yu Ning had said that he needed to provide five furnaces of Qi Gathering Pills to the Sect each month; this was a mandatory task that couldn't be delayed.
It took him about seven days, but these five furnaces of Medicinal Pills were finally refined.
The remaining waste pills wouldn't be wasted either; he collected them, as they could be enhanced into Top-Grade Qi Gathering Pills in the future.
During these seven or eight days, all the items purchased from the Treasure Storage Hall had also been enhanced by He Pingsheng.
First, the Low Grade Magical Artifact, the Flying Sword, after enhancement, yielded two Top-Grade Flying Swords.
Of course, their grade was still Magical Artifact.
Each Flying Sword now had four Restrictions.
Secondly, the Low Grade Magical Artifact, the Green Wood Shield, after enhancement, yielded two spiritual shields.
One was the Tengjia Shield, and the other was still the Green Wood Shield.
However, the enhanced shields were also Top-Grade Magical Artifacts, possessing four Restrictions.
The Talisman, the Fireball Talisman, after enhancement, yielded two Exploding Bomb Talismans.
The Talisman, the Ice Needle Talisman, after enhancement, yielded two Ice Arrow Talismans.
The four Talismans, after enhancement, had significantly improved in grade; although they were still First Grade Talismans used by Qi Refinement Stage Cultivators, their power had increased several times over.
Looking at these treasures, He Pingsheng began to calculate frantically in his mind.
The four Talismans, Exploding Bomb Talisman and Ice Arrow Talisman, he would definitely keep for himself for self-defense.
He would keep one Flying Sword, and he could keep one of the two shields.
This way, he could sell one Top-Grade Magical Artifact Flying Sword, one Top-Grade Magical Artifact Green Wood Shield, and a Top-Grade Magical Artifact Pill Furnace.
Three!
The price of a Flying Sword wasn't entirely clear, but he could roughly guess.
For example, a High Grade Flying Sword was about two hundred-plus Spirit Stones, so a Top-Grade one would certainly not be lower than three hundred-plus, possibly even four hundred.
The price of a Pill Furnace couldn't be lower than a Flying Sword.
The most expensive, however, was this Green Wood Shield.
Among all Magical Artifacts, defensive Magical Artifacts often had the highest prices; He Pingsheng didn't know the specific reason, but from what he observed in the shops, the price of this item was very high.
A High Grade Green Wood Shield could sell for a high price of four hundred Spirit Stones, so what about a Top-Grade one?
Eight hundred? Or a thousand?
Thus, these three Magical Artifacts could sell for approximately one thousand five hundred to two thousand Spirit Stones, which was almost enough!
Enough to buy a Storage Pouch.
Originally, He Pingsheng had wanted to go to the Treasure Storage Hall again to buy some Magical Artifacts to enhance, but he ultimately abandoned that idea.
It was better not to, lest he be noticed by others.
Only by being cautious could he last long.
Picking up the five furnaces of Medicinal Pills, He Pingsheng left his door.
Master Yu Ning was in closed-door cultivation, and she had previously said she would be in seclusion for a long time, so He Pingsheng didn't disturb her; he went directly to the entrance of Senior Sister Zhao Ling'er's small courtyard.
There was no sign hanging at the entrance of Zhao Ling'er's courtyard, indicating that she was not in closed-door cultivation.
He could simply knock on the door.
“Junior Brother?” Zhao Ling'er looked at He Pingsheng in surprise and said, “You are…”
He Pingsheng smiled honestly and took out five porcelain bottles: “Senior Sister… These are the Medicinal Pills refined this month. Please take a look. Master said I just need to hand them over to you!”
“That's great!”
Zhao Ling'er was immediately overjoyed and said, “Junior Brother… please come in and sit!”
“Yes!”
He Pingsheng didn't stand on ceremony and followed Zhao Ling'er into her courtyard.
Zhao Ling'er's courtyard was roughly the same size as He Pingsheng's, almost identical, but the visual appeal was much better.
This woman had planted many flowers and plants in the courtyard, creating a vibrant display.
And it smelled very fragrant too.
He Pingsheng's gaze passed over these flowers and plants, but landed on the earthy yellow light film at her door: What was that thing?
