The reason why Li Xiaojun exclaimed was mainly because he discovered that the system absorbed the spiritual power of this chaotic spirit stone countless times faster than the top-grade immortal stone.
Li Xiaojun did some calculations and found that using this Chaos Spirit Stone to replenish energy is hundreds of billions times faster than using the top-grade Immortal Yuan Stone.
In other words, the grade of this Chaos Spirit Stone is at least five grades higher than that of the Top Grade Immortal Yuan Stone.
It is very likely, just as Li Xiaojun guessed, above the fairy spiritual energy is the innate spiritual energy, and above the innate spiritual energy is the chaotic spiritual energy.
If calculated in this way, the innate spiritual energy should also have energy crystals and can become innate spiritual stones.
A piece of low-grade innate spirit stone should be comparable to one hundred top-grade immortal stones.
A piece of medium-grade innate spirit stone can look down upon ten thousand pieces of top-grade immortal essence stones.
One piece of top-grade innate spirit stone is equivalent to one million top-grade immortal stones.
One piece of top-grade innate spirit stone should be equivalent to 100 million top-grade immortal stones.
The Chaos Spirit Stone, which is more advanced than the top-grade innate spirit stone, is equivalent to 10 billion times the top-grade immortal stone.
The energy of the top-grade immortal stone, which is a hundred billion times greater, made Li Xiaojun completely crazy.
The system absorbs this Chaos Spirit Stone, not only the speed is increased by 10 billion times compared to the best-grade Immortal Yuan Stone, but the total energy of one Chaos Spirit Stone is also equivalent to 10 billion best-grade Immortal Yuan Stones.
Hundreds of billions of top-grade immortal stones, which is equivalent to the total amount of top-grade immortal stone mines that Li Xiaojun stole from the demon clan last time.
Although purifying Chaos Spirit Stone is rather troublesome and it takes about ten years to purify a piece of Chaos Spirit Stone, the quantity is huge.
A top-grade immortal stone is equivalent to one hundred trillion energy values.
So how much energy value is equivalent to 10 billion top-grade immortal stones?
Astronomical figures.
According to this energy value, Li Xiaojun probably only needs to absorb ten Chaos Spirit Stones to upgrade the system.
Thinking of the sixth system upgrade, Li Xiaojun suddenly felt a strong sense of anticipation.
So Li Xiaojun decided to continue refining the chaotic spiritual energy in the Demon Realm, and then try to upgrade the system as soon as possible.
…
Do it when you think of it.
Li Xiaojun felt that the chaotic spiritual energy nearby had become a little thin because he had been constantly refining it, so he flew directly trillions of kilometers away and came to a place where the chaotic spiritual energy was even richer.
Then, Li Xiaojun used his spiritual sense to attract all the immortal spiritual energy within his perception.
These immortal spiritual energies were attracted by Li Xiaojun and quickly swarmed towards him.
At the same time, Li Xiaojun was also constantly extracting the chaotic spiritual energy from these spiritual energies.
The reason why Li Xiaojun was able to purify the chaotic spiritual energy was mainly due to the system space.
He only needs to collect the fairy spiritual energy into the system space, and the system space will naturally separate the chaotic spiritual energy.
It’s a pity that the system space cannot directly absorb the chaotic spiritual energy, but needs to compress the chaotic spiritual energy into chaotic spiritual stones.
Ten years passed in a flash.
Ten years later, Li Xiaojun once again compressed a fist-sized Chaos Spirit Stone.
After Li Xiaojun completely compressed the chaotic spiritual energy, most of the immortal spiritual energy perceived by his spiritual consciousness was almost purified by Li Xiaojun.
There is not much chaotic spiritual energy left in it, only pure fairy spiritual energy remains.
At the same time, many demons perceived by Li Xiaojun's spiritual sense suddenly discovered that their training speed had increased by at least ten times while they were practicing.
On this day, two demons from the celestial realm were very nice to this side.
"Huh? Such a strong demonic aura." A demon from the celestial realm couldn't help but sigh.
Hearing this, another demon celestial being felt it and said in surprise: "The poisonous spirit energy in the demon spirit energy is gone."
"Really? There really isn't any poisonous spiritual energy!"
"What's going on? Why is there no poisonous aura among the demonic aura here?"
“I don’t know, but this is a good thing. When the poisonous demonic spirit energy is used for cultivation, we also have to find a way to remove the demonic spirit energy that cannot be absorbed, which greatly delays the cultivation time.”
"Now that the poisonous spiritual energy is gone, we may be able to find a place to practice. The demonic spiritual energy here is even more dense than that in Kunlun Realm, which is great for practice."
"Yes, we should find a place to practice."
Soon, the two demons from the Heavenly Fairyland found a place to practice.
Just when the two demons from the Heavenly Fairyland were looking for a place to practice, Li Xiaojun had already arrived two trillion kilometers away and began to extract chaotic spiritual energy.
…
Next, every ten years, Li Xiaojun would move to a new place.
Time flies and a hundred years have passed.
On this day, Li Xiaojun finally heard the long-awaited system upgrade prompt.
[System prompt: The system has reached the upgrade conditions, please ask if you want to upgrade! ]
In order to ensure the safety of the upgrade, Li Xiaojun did not upgrade in the Demon Realm, because the system functions are unavailable during the system upgrade.
He was afraid that the system would be discovered by the demon clan when it was upgraded.
So, he chose to teleport to Earth and then start upgrading.
"upgrade!"
After arriving on Earth, Li Xiaojun chose to upgrade without any hesitation.
[System prompt: Upgrading...]
Ten years later.
【System prompt: System upgrade successful. 】
Upon hearing that the system had been successfully upgraded, Li Xiaojun quickly checked the functions of the system after the upgrade.
This system upgrade did not bring any new features, but it strengthened four existing functions.
Although it only strengthens the existing functions, it can be called abnormal.
First of all, it strengthens the function of merit.
In the past, Li Xiaojun could only add some merits to himself.
