Yi Tianyun felt that it should be about the same, he didn't want to throw it into the store and buy it back. This means that he will lose a lot of money, which he really does not want to see.

He estimated a little, if he did this, his madness value would definitely be in deficit! You must know that this time he destroyed so many evil spirit clans, and the madness value he obtained must be a lot, but in the face of the seven-rank light core, it still seems to be stretched.

Immediately, he gritted his teeth and smashed the seven-grade light core into it, and then the light core began to bloom with dazzling light.

"Ding, congratulations to the player 'Yi Tianyun' for successfully upgrading the seven-grade light core to the eighth-grade light core!"

With a crisp and pleasant sound, Yi Tianyun successfully promoted this seven-grade core to an eight-grade core. The seventh-grade core in the body immediately bloomed with a more dazzling white light, and it was soon upgraded to an even smaller eight-rank core with energy compressed to an even more amazing level!

It still looks like it's still white light, but it's more shining and more transparent than before.

"Is this the core of the eighth grade, it's really a success!" Yi Tianyun was happy in his heart, he felt that there was just a little bit of it, that is, he felt that there should be no problem if he tried it a little.

Now it seems that there is really no problem with him, and he has successfully upgraded.

"From this point of view, it is not difficult to improve the other cores. ”

Yi Tianyun thought of the other cores, the grades were relatively low, if they could all be improved, then their own strength would increase a lot. Now the light core that has been upgraded to a higher level has made him feel his strength, and there has been a great improvement, especially in the cohesion of the light attribute, whoever plays the light attribute in front of him is looking for death.

"Try it first, the effect of this eight-grade light core!"

Yi Tianyun was a little excited, but he didn't know what the effect of the Eight Grades Core was. This is the first time he has an eight-rank core, and the effect should be very good.

Immediately, he flew out, and soon came to the outermost area, and the pitch-black energy outside shrouded the outside even darker. A sense of pressure rushed towards him, which made him feel a little uncomfortable. This discomfort is not caused by any pressure on him, but a kind of discomfort.

It's like an environment that doesn't quite fit them to survive. Staying here for a long time was impossible, it would make him uncomfortable. Of course, with his current cultivation, there is still no problem with permanent residence, but for other cultivators, especially those whose cultivation is relatively low, that is, it is difficult to break through in cultivation.

The change of environment is very important, once it is not suitable for survival, let alone breakthrough. Especially this kind of pitch-black energy, it also has a suppressive effect, so that their power cannot be exerted.

Many cultivators have discovered this situation, but they are powerless to change it, so they can only bear this effect.

Yi Tianyun first chose the top of the Divine Domain, and then sacrificed the eight-grade light core, and in an instant, his body turned into a dazzling sun, shining brightly, and bloomed all around.

At the moment of blooming, the pitch-black energy sticking to the sky really began to dissolve, and the speed was not fast, it could only be said to be relatively slow. At a speed visible to the naked eye, it begins to fade little by little, degrading into the color it should be.

Although it is still pitch black, this pitch black piece does not have the slightest sense of pressure, but there is still a sense of intimacy.

"It's kind of working...... Keep me wide open!"

Yi Tianyun let out a loud shout, the light core in his body was completely opened, and a light dragon roared out, frantically devouring this pitch-black energy. This time the speed finally increased, and in the blink of an eye, part of the area was swallowed up, which was quite amazing.

"The effect is not bad, but the consumption is a little bigger. ”

Yi Tianyun was happy about this, although the speed was still very slow, but on the whole, it was already very good. At least it can be broken, not by all means, there is no way to get rid of it.

He continued to clear up, and the many cultivators below all saw Yi Tianyun's actions here. Especially some domain masters who didn't leave, when they saw this scene, they were all stunned and frightened by this scene.

"Didn't you say that there is no eight-rank light core, why did you suddenly have it...... This clearing speed is really fast, we have worked hard, at most we are clearing a little bit, which is worthy of the light core of the nemesis. ”

"Yes, didn't the alliance leader say that there is no eight-rank core, why did it suddenly exist? It's just that according to this clearing speed, it's still a little slower, if only it could be a little faster. ”

"Isn't that fast enough, I was desperate to clear a little bit. The speed of the alliance leader is already very fast. It should be said that it would be nice to be able to clear it!"

They were still very pleasantly surprised, but fortunately they didn't leave, so they didn't miss this picture. The massive black energy was cleared, and they were happy to see it. If this continues, this divine domain will still be cleaned up.

It's just that it's not just this area that has been polluted, but most of the Inner Divine Domains! Most of the Inner Divine Domains have been gradually polluted, and some of them have become very stubborn, and it is very difficult to get rid of them.

Yi Tianyun's side must be able to clean it up, but the speed is very slow, it seems that the speed is not bad, but if it spreads to the entire Inner God Domain, it seems a little slow.

I'm afraid it will take a long time to clean up this place. In this way, it will take a long time to clean up the next god domain.

In this case, I don't know if it will all be cleared before the Battle of the God Emperor begins.

"Clean up the black blood and gain a thousand compression experience. ”

"Clean up the black blood and gain 600 compression experience ......"

......

At this time, each bit of black blood is cleaned, and different levels of experience are gained, which varies with the change in concentration. It's just that you have less experience gained, but if you continue to gain more experience, you will definitely be able to accumulate more experience. Anyway, it's better than nothing, even if it's mosquito meat, it's meat.

"It's good to still gain experience, but it's too slow......"

Yi Tianyun frowned, if he changed to the Nine Rank Light Core, it would definitely be faster. But where can he have a nine-rank light core, he can't buy a nine-grade core if he sells him! Not to mention the nine-grade core, I'm afraid that even two eight-grade light cores, judging from the current crazy value, can't afford it at all.

When he was thinking about how to solve it, he suddenly remembered one thing - the Orb of the Evil God!

"If I let the evil spirit puppet use the Evil God Orb to absorb it, will it be faster?" Yi Tianyun's eyes lit up, this is the so-called fighting poison with poison!
