If that was the case, then the only things that could be obtained after the Lantern Festival were low-grade spirit stones. As for mid-grade spirit stones, high-grade spirit stones, top-grade spirit stones, and ultimate spirit stones, they could not be obtained with the Apocalypse Pearl.
wrong!
Yuan Xiao suddenly remembered an omission. These low-grade spirit stones had been purified once before. They were low-grade spirit stones purified from miscellaneous spirit stones. They were not low-grade spirit stones themselves!
If it is a low-grade spirit stone, can it be purified into a medium-grade spirit stone?
Low-grade spiritual stones, where can I find ready-made low-grade spiritual stones? !
Yuan Xiao's head suddenly buzzed. Yes! Aren't the low-grade spirit stone samples sent by Yunhai Gate just ready-made low-grade spirit stones?
Yuan Xiao excitedly put the low-grade spirit stone sample sent by the sect together with the Apocalypse Pearl. Although this sample was cut and very small, it was undoubtedly a real low-grade spirit stone.
Yuanxiao stared at the low-grade spirit stone sample nervously.
After about half an incense stick of time, the low-grade spirit stone sample began to change. A layer of white powder oozed out of it, and the amount of white powder increased.
After about an incense stick of time, the low-grade spirit stone sample stopped changing, and no more white powder seeped out. However, a pleasant spiritual aura was already in the air.
Yuanxiao picked up the low-grade spirit stone sample and blew gently. The white powder dispersed, revealing a lustrous green spirit stone!
Green Spiritual Stone! A mid-grade Spiritual Stone!
Zhang Dahai had explained to them before that low-grade spirit stones were white, medium-grade spirit stones were green, high-grade spirit stones were blue, top-grade spirit stones were purple, and the legendary top-grade spirit stones were dark orange! This purified green spirit stone was surprisingly a medium-grade spirit stone!
It turns out that it's not that the Apocalypse Pearl cannot purify low-grade spirit stones into medium-grade spirit stones, but that the miscellaneous spirit stones cannot be purified and upgraded twice in a row! If it is a low-grade spirit stone, then it can evolve into a medium-grade spirit stone!
Yuan Xiao held the green middle-grade spirit stone in his hand, feeling the rich spiritual energy. He continued to think: Can the Apocalypse Pearl also purify middle-grade spirit stones into high-grade spirit stones?
I don't have any ready-made mid-grade spirit stones at the moment, so I can't complete this experiment.
Let's take this medium-grade spirit stone obtained by purifying the sample and test it first! But according to the test just now, it is estimated that it cannot be upgraded further. When there is a ready-made medium-grade spirit stone in the future, we can conduct this complete test.
Yuanxiao placed the green medium-grade spiritual stone that had been purified once next to the Apocalypse Pearl, letting the two lean against each other, and continued to observe.
A stick of incense has passed...
An hour passed...
Three hours passed...
There was no change in the green mid-grade spirit stone, just as expected.
The current conclusion is: Apocalypse Pearl can purify existing spiritual stones once and upgrade them to higher quality spiritual stones of the previous level. However, it cannot purify twice in a row, and spiritual stones that have been purified once cannot be purified and upgraded again.
Of course, this conclusion may not be completely correct. It can only be said that it is a temporary conclusion. Yuan Xiao deeply feels that there are many mysteries in the Apocalypse Pearl. What he knows now may be just the tip of the iceberg, and even the current understanding may be wrong!
For example, the small depression on the Apocalypse Pearl, if you stare at it for a long time, you will feel that your soul is being pulled and your head is splitting. What is this small depression? What is hidden inside?
Yuan Xiao is weak now, and is far from qualified to explore. If he does not fall in the future, he may reach a certain level of cultivation, and these problems will be solved. Fortunately, these problems are not urgent.
There are several things that Yuanxiao needs to prioritize right now.
