As time passed, there were fewer and fewer black creatures flying in the sky. As soon as the corrupted cores escaped from the black air, they would be blasted into pieces by the magicians in the library without leaving any traces.
The black gas that lost its attachment point became an ownerless object. Some black creatures wanted to keep the black gas for themselves, but there was a limit to the amount of black gas that the core could carry. After the black creatures grew to a certain size, their bodies reached saturation and could no longer absorb the black gas.
More and more black gas began to fill the air, and its range increased as more black creatures fell.
Without the control of the God-Destroying Light, the black air began to perform its own functions. As long as someone approached it, the black air would make despair appear in front of those people and induce them into a coma.
The magicians could not fight in the black fog for long.
The few remaining black creatures noticed this and hid in the black fog.
Li Yan captured a ball of black air and analyzed it despite the painful memories of the past.
Unfortunately, the technology for specializing in magic power and the technology for creating underground mazes were lost. After studying for a long time, Li Yan could only come up with a bird.
Finally, Li Yan tried another method and was able to barely turn the exclusive magic power back into ordinary magic power.
This method can be simply summarized as "complete burning", which completely burns the half-burned "charcoal" into ashes, giving magic power new life.
After finding a way to cure the black air, Li Yan immediately taught this magic to other young magicians, and it flattened the black air that gathered in the air.
In fact, after a long period of accumulation, the library already has the ability to deal with the black air.
However, in order to firmly grasp the bargaining chips in negotiations with the goblins and obtain the greatest benefits from them, the library did not attempt to conduct a deeper study of the darkness underground, but only explored it superficially.
If the Library of All Things had captured some samples of the black gas earlier and compared it with the ancient books, it would have known that the black gas was most likely the exclusive magic power mentioned in the ancient books, and it would have found a solution and would not have been delayed until the Light of Destruction grew to that level.
It is not that they don't have their own difficulties.
In order to maintain the existence of the library, the Fairy Kingdom is indispensable.
If there were no goblins, it would be difficult for people to quickly find the knowledge they want in the vast ocean of books.
In order to firmly control the goblins, the talents of the Special Countermeasures Committee completely disregarded the feelings of the goblins and used them as tools. From 9 to 5, it became 996 every day, and they had to work overtime from time to time to accumulate merit.
The members of the Special Countermeasures Committee also strictly followed the instructions left by their predecessors and would not take action rashly until the black energy was on the verge of collapse.
Very few people try to change this system. After all, no one wants the Library of Everything that has been passed down for thousands of years to be destroyed in their own hands.
Unfortunately, this outdated system eventually caused problems and almost endangered the library itself.
Fortunately, it was resolved without any danger, otherwise the consequences would be disastrous.
Taking this opportunity, the relationship between humans and fairies will definitely undergo tremendous changes.
There is only one person who can maintain the relationship between humans and fairies.
After this incident, Yang Yu undoubtedly became the savior of the goblins. If he could negotiate with the goblins on behalf of the library
Perhaps, the relationship between humans and fairies can be improved, so that humans no longer simply treat fairies as tools, but can achieve true symbiosis.
After clearing the black air in the sky, following the advice of Kaka and Yang Yu, Li Yan took the magician deep into the underground ruins and cleared away all the black air lingering in the underground ruins.
It was the first time for many people to know that there was a fairy kingdom under the library, and that there were underground ruins under the fairy kingdom.
They walked through layer after layer of ruins, marveled at the imaginative murals on the walls, and became curious about the ancient civilization. They planned to search the library for information after returning.
However, they don't know yet that when they return to the ground, everything about the fairy kingdom will be regarded by them as just a dream, a dream that will soon be forgotten.
After clearing the ruins and the endless flower fields and confirming that there was no black air, the matter came to a perfect end.
Standing on the ruined castle, Kaka, the Fairy King, thanked all the humans present on behalf of all the fairies, and presented them with the rewards that the fairies had worked so hard to prepare.
Most of these rewards are some white magic stones, which are made by infusing the magic of fairies into the withered flowers collected. Because of the magic of fairies, these magic stones can easily resonate with other magic and burst out with more powerful power.
As for the disadvantages, these white magic stones are disposable. After use, these white magic stones will burn on their own, turn into white smoke and disappear completely. They cannot be reused, and the annual output is very limited.
These magic stones were originally prepared for sealing humans. Now there was no need for anyone to go to the fairy kingdom to resolve the darkness, so Kaka took out all the white magic stones in stock at once and distributed them to everyone present.
According to the agreement to rescue the goblins, Yang Yu got much more magic stones than others.
And this is just one of his rewards.
When fighting against the Light of Destruction, Yang Yu also asked Kaka for some things, and those rewards could only be collected from Kaka after the ceremony was over.
Finally, Kaka personally presented everyone with the nectar collected by the fairies, and the commendation ceremony was completed in an orderly manner.
"Thank you for everything you have done for the Fairy Kingdom. We fairies will always remember your contributions. That's all."
Riding on the book, Li Yan approached the Fairy King Kaka and said in a friendly manner: "This time the Fairy Kingdom has survived the crisis safely, but I'm afraid things won't end so easily. You must be prepared to negotiate with humans."
Kaka has an impression of this old man.
He knew that this wasn't the first time that Liyan had come to the Fairy Kingdom.
Once as a trial-taker, and this time as a library elder.
Kaka also vaguely sensed the library's attitude towards the Fairy Kingdom, but did not say it openly because they, the fairies, really needed the help of humans in order to gain a foothold in this world.
"Don't worry, I will prepare everything and negotiate with them. I believe that as long as you sincerely wish to coexist peacefully with us, your library and our fairy tribe can still coexist as before."
After hearing the promise of the Fairy King, Li Yan didn't say anything, but just nodded slightly and looked at Yang Yu beside him.
