He had finally figured it out.
True Understanding Level artifacts were simply not something that could be matured with a mere 2 billion incense values.
The reason why the last 10% maturity did not budge was that the system was telling him that to mature a True Understanding Level artifact, he needed a massive amount more incense values to fill it.
And this amount would not be less than the previous 90%.
That is, no less than 2 billion!
Qin Hao wanted to mature the gourd.
He needed to save up tens of billions more incense values before he could do so.
Otherwise, it was just a drop in the bucket.
So with these 500 million incense values, Qin Hao was not going to spend them on the gourd.
Instead, he purchased Spirit Swords from the System Mall.
With 500 million incense values, Qin Hao spent 100 million.
He bought 30 Spirit Swords in the Mall.
Each one was at the Infinite Level.
Qin Hao gave 10 to Li Yixi.
He asked her to cultivate the Sword Control Technique.
Then, he put the remaining 20 Spirit Swords into his Yellow Gourd, to expand the storage capacity within the gourd!
However, after the 20 Infinite Level Spirit Swords were put into his Yellow Gourd,
Qin Hao found that the Yellow Gourd, which had already advanced to Creation Level, did not change in level after swallowing these Spirit Swords.
It seemed that to upgrade further, merely storing Infinite Level Spirit Swords was no longer effective.
At least he would need Spirit Swords of Immortal Spirit Level or Creation Level to be stored inside.
In other words, after reaching Creation Level,
The Infinite Level Spirit Swords Qin Hao had were too low for the Yellow Gourd.
It simply looked down on them.
Naturally, it would not upgrade.
Then bring better swords!
Unfortunately, the refining value of Qin Hao’s Purple Cloud Divine Thunder was too low.
He wanted to use the Purple Cloud Divine Thunder to temper these Infinite Level Divine Swords, but the speed was too slow.
In the Purple Gourd, he wanted to make Essence Pills but lamented not having the materials for refining.
To upgrade the Divine Swords, he couldn’t keep up with the efficiency!
If he could upgrade all of the Divine Swords in his gourd right now to True Martial Level or even Immortal Spirit Level, Qin Hao’s own strength would surge by a large margin.
Now, Qin Hao had two paths he could take.
First, refine the Purple Cloud Divine Thunder, then use it to temper the Divine Swords, which could elevate them to True Martial or Immortal Spirit Level.
Second, create Essence Pills, use the Refining Essence and Transforming Origin Divine Power of the Purple Gourd to produce a large number of Essence Pills, and use them to upgrade the Divine Sword levels!
The first path was too slow.
This Purple Cloud Divine Thunder was of too high a level.
For Qin Hao to refine it now, he would only be improving at an efficiency of 0.001.
Qin Hao thought about quickly increasing the refining value of the Purple Cloud Divine Thunder.
Without several decades or a century, it was simply not feasible.
That meant that he could only take the second path.
Create a large number of Essence Pills.
But he also needed raw materials to make Essence Pills with his Purple Gourd!
At this moment, Qin Hao suddenly remembered.
Wasn’t there still a Vampire locked away in his Purple Gourd?
It had been several years.
Vampires were naturally excellent materials for Refining Essence and Transforming Origin!
A common Vampire could yield one Essence Pill.
If he encountered one with a high level, a single Vampire Duke could be squeezed for dozens!
And if he caught a Prince of the Vampires, pure Blood Species, then that would be a jackpot.
A Prince and pure Blood Species could produce at least hundreds of Essence Pills.
Qin Hao had heard that there were Four Great Blood Emperors among the vampires, right?
If he could capture a Blood Emperor.
One Blood Emperor, that’s thousands of Essence Pills!
So many Essence Pills would make upgrading his Divine Swords a breeze, wouldn’t it?
How could he have forgotten this?
Qin Hao brought the Vampire to mind.
Why not have the Red Robed Taoists of Qingyun Mountain make a trip to the West and topple the Western Bloodline’s stronghold, capturing them all to refine Essence Pills for him?
Thinking so, Qin Hao took off the Purple Gourd from his waist.
With a slap, he smacked the Vampire Duke, who had been locked up inside for several years, out of the gourd.
Qin Hao declared, "Wake up! Little brother, your sentence is over! Now it’s your chance to atone for your crimes! Lead the Taoists obediently to the West, capture the Vampires, and there are hefty rewards for you!"
