Seventy-three percent.
Outside the Death Star vortex, Si Yuanbai, Diao Fei, Yu Fei and others fought desperately to delay time for Long Yu, and Long Yu's progress inside the Death Star vortex was also quite fast.
After half a day, Long Yu finally mastered 73% of the Nine Nether Seal. According to its rule that it becomes more difficult to master as time goes by, about three days later, Long Yu will master 80% of the Nine Nether Seal.
Now, Long Yu has no idea how long Si Yuanbai and others outside can delay him, and he doesn’t even know that Concubine Yu has arrived.
However, deep down in his heart, Long Yu was in an extremely urgent state. He knew that every minute he mastered the Nine Nether Seal could lead to a huge crisis.
He must use all his energy at all times to absorb the aura of the Nine Nether Dragon Emperor in the Nine Nether Seal, speeding up, speeding up, and speeding up again!
But at this moment, he finally felt that the spiritual soul of the great master who had broken into the vortex of the Death Star seemed to be closer to him, and was already not far from him. If he had any means, he would probably use them now.
Now, Long Yu only exists in the state of spirit and soul. Without a physical body, he does not have the help of the Pure World Body. Facing the impact on the spiritual level, he may not be able to withstand it!
"We're almost there. It looks like he has a way to detect my position and is slowly moving towards me. This person must have a very high level of cultivation!"
Long Yu became increasingly alert and finally came out of the state of absorbing the aura of the Nine Nether Dragon Emperor. He knew that the most important thing now was to save his own life rather than to buy a little bit of time.
After all, if his spirit was destroyed by the other party, then everything would be over. Long Yu would never be able to master the Nine Nether Seal to 80% because he was already dead.
"I've caught up with you. A little bastard like you who is only at the peak of the Emperor Realm, what methods can you use in a purely mental state? If you can't, then you have to die."
Jiyuan Daoyi's spiritual soul floated over like a stream of air, and looked extremely ferocious in the vortex of the Death Star. His khaki soul floated over and immediately released a mental shock towards Long Yu's spiritual soul!
Jiyuan Dao was already familiar with this method. In the outside world, he could even use this trick to wipe out the souls of thousands of strange beasts in an instant, and use it to kill opponents weaker than himself, very easily.
Now facing the spiritual soul of Long Yu, who is at the peak of the Emperor Realm, Jiyuan Daoyi feels even more relaxed. However, he also knows that he must pay attention to the fact that Long Yu is gradually mastering the Nine Nether Seal.
It is possible that he could use the power in the vortex of the Death Star, but Jiyuan Daoyi was, after all, a powerful being at the level of a great master. His spirit had long been tempered and was extremely solid. As long as the power in the vortex of the Death Star did not cause a riot, he would be difficult to kill.
"Nine Netherworld Divine Scripture!"
Long Yu watched the opponent's mental shock wave coming at him, and immediately activated the Nine Nether Seal. With 73% of the Nine Nether Seal under his control, he successfully activated the power of a nearby Nine Nether Divine Scripture to resist the opponent's mental shock.
The power of the Nine Netherworld Divine Texts in the vortex of the Death Star are all revelation-level Nine Netherworld Divine Texts. This is a power that only gods can possess. Few people in the world outside the sky have heard of it.
Even though Long Yu can't control much now, it should still be effective if he uses it to resist a little.
I saw that the power of the Nine Nether Divine Script instantly condensed into a gust of wind, rushing towards the opponent's mental shock wave, quickly enveloping the mental shock wave completely, and then the two sides collided and exploded, and the invisible force created a vortex of power at the original location!
After the vortex of power was generated, it gradually became smaller until it disappeared without a trace, but Jiyuan Daoyi's mental shock wave towards Long Yu was blocked by Long Yu.
"I do have some skills, but the attack just now was only less than 10% of my Jiyuan Daoyi's strength. The reason why I didn't use all my strength to kill you instantly was because I was afraid that the force would be too strong and cause a riot of power in the Death Star's vortex..."
Jiyuan Daoyi was a little surprised that Long Yu blocked the mental shock wave, but he didn't take it too seriously. This also made him realize the current level of Long Yu's mastery of the Nine Nether Seal.
"About 70 percent! I don't have much time left."
Jiyuan Daoyi had no time to waste here, nor did he say any nonsense. In fact, the spirit and soul that had arrived in the vortex of the Death Star were in a state where it was almost impossible for them to communicate with each other. Jiyuan Daoyi couldn't speak even if he wanted to.
In an instant, Jiyuan Dao concentrated 30% of his spiritual impact force and released it towards Long Yu, bringing up a terrible airflow, breaking the Nine Nether Divine Texts along the way, and directly attacking Long Yu!
In the Death Star vortex, Long Yu's various methods could not be used, but fortunately, in the Death Star vortex, the opponent could only use mental shock as a method.
Otherwise, in the outside world, a strong man at the level of a great master would only need to raise his hand to kill Long Yu, and there would be no need to go through so much trouble.
"The strength of this mental shock wave is three times stronger than before!"
Long Yu concentrated his mind all at once. He didn't know what fraction of the opponent's strength this mental shock wave represented, but fortunately, this shock wave was still within the range of his defense ability.
"Revelation-level... Nine Nether Godly Scripture!"
Long Yu activated the Nine Nether Seal and fiddled with the revelation-level Nine Nether Divine Texts around him again, causing them to condense into a high-speed spinning whirlwind that flew towards the mental shock wave.
During this process, Long Yu gained some understanding of the revelation-level Nine Netherworld Divine Text. Although this did not mean that he was about to comprehend the revelation-level Nine Netherworld Divine Text, it would be of great help to him in comprehending the revelation-level Nine Netherworld Divine Text in the future.
This time, the power of the revelation-level Nine Nether Divine Script that Long Yu activated was about three times stronger than before. This was almost his limit. If the opponent could send out a stronger mental shock wave, Long Yu might not be able to withstand it.
However, the mental shock wave and the revelation-level power of the Nine Netherworld Divine Script in front of him collided with each other, and soon produced a strong explosion, resulting in the appearance of a power vortex that was more than ten times larger.
This vortex of power almost affected the spiritual souls of Long Yu and Jiyuan Daoyi, causing some changes in the hearts of both of them.
Jiyuan Daoyi couldn't help but move to the side, because this vortex of power might completely devour his spirit and soul, causing him to die here, and he couldn't take this risk.
However, Long Yu discovered that the other party was avoiding this vortex of power.
Just at this time, Long Yu absorbed a large amount of the Nine Nether Dragon Emperor's aura from this vortex of power and successfully comprehended 74% of the Nine Nether Seal!
At this time, Long Yu activated the Nine Nether Seal, and was barely able to slowly change the direction of movement in the Death Star vortex. He did not hesitate to go in the opposite direction of the opponent's retreat, and the distance between the two sides quickly widened.
That vortex of power existed more than ten times longer than the vortex created by the first impact of power between the two sides. It was not until a long time later that this vortex of power stopped spreading and then slowly dissipated.
Fortunately, the power explosion that Jiyuan Daoyi imagined did not occur. It seems that this level of power impact is still within the tolerance range of the Death Star vortex.
"Next time, 40%!"
Jiyuan Daoyi was in a bad mood because he found that when the vortex of power disappeared, the distance between him and Long Yu was widened again. If he wanted to catch up, it would take at least another hour.
Sometimes, an hour may be the key.
Jiyuan Daoyi calmed himself down and quickly flew towards Long Yu again. The distance between the two began to close again. However, this time Jiyuan Daoyi's speed of approaching Long Yu was slower than before, because Long Yu now also had the ability to actively move in the Death Star vortex.
Seventy-four percent control of the Nine Nether Seal is just a dividing point; seventy percent allows Long Yu to step into the Death Star vortex, and only until seventy-four percent can he move freely in the Death Star vortex.
Now, Long Yu was fleeing towards the far center of the Death Star's vortex. The closer he got to the center of the Death Star's vortex, the stronger the Nine Nether Dragon Emperor's aura became, and the faster he could absorb it.
After more than an hour, Long Yu had not made any further progress in his mastery of the Nine Nether Seal, but the spiritual soul of the great overlord had once again caught up with him.
"That's enough, die!"
Jiyuan Daoyi's spirit was filled with coldness. A mental shock wave containing 40% of his strength instantly blasted towards where Long Yu was, blasting open the Nine Netherworld Divine Texts along the way and going straight to Huanglong, trying to wipe out Long Yu's spiritual soul!
"It's stronger than before! Fortunately, I have mastered more of the Nine Nether Seals, otherwise, I might be finished."
Long Yu's heart skipped a beat, and he activated the Nine Nether Seal at the fastest speed, condensing a barrier composed of revelation-level Nine Nether Divine Scriptures, blocking him behind.
Although he only mastered one percent more of the Nine Nether Seal than before, the defensive capability of this barrier formed by the revelation-level Nine Nether Divine Script was definitely one third stronger than before!
In terms of strength, it is just enough to withstand the opponent's mental shock wave.
The mental shock wave instantly hit the Nine Netherworld Divine Script Barrier. A wave of terrifying power spread out, causing the surrounding cyclones to become chaotic and forming a larger vortex of power again.
The appearance of this vortex of power even sucked in the spiritual souls of Jiyuan Daoyi and Long Yu. The two watched the vortex of power expand, but they were unable to escape the influence of the vortex of power.
"damn it!"
Jiyuan Daoyi cursed inwardly. He originally felt that his mental shock wave was enough to annihilate Long Yu's spirit, but now it seems that it is still a little short.
Not only that, this time the power collision between the two sides directly involved both of them. For a moment, no one could leave this place, and after being affected by the vortex of power, the spirits and souls of both of them began to be damaged!
