When Liao Cheng couldn't think of any way to crack the light mask, and Xue Yi was still asleep, in the Holy City, the battle had already reached a fever pitch.

The water-type killing dragon cooperated with the fire-type killing dragon, and the combat effectiveness was greatly enhanced.

In less than three hours, they had broken through the fire shield of the Xuandi Holy Envoy, the thunder shield of the Haodi Holy Envoy, and then the light shields that had been in the four Holy Cities in a row.

At this time, the last light mask was only less than half an inch left and was about to be broken. Outside, the slaying dragons screamed incessantly, spitting fire and water energy into the light shield.

The Xuandi Holy Envoy and the Haodi Holy Envoy, with all the dragon knights, continued to inject energy into the last light shield. This slowed down the speed at which the mask dissolved.

However, this situation only lasted less than five minutes, and after a water killing dragon flew over not far away to join the battle, the situation immediately changed, and I saw that the speed of the light mask dissipated faster, almost reaching the terrifying level, and in just a moment, it reached the limit that the light mask could bear.

At this time, the look of despair in the eyes of the Xuandi Holy Envoy flashed. It seems that the outsider's mission has failed.

A trace of despair flashed in the eyes of the Haodi Holy Envoy, but this trace of despair was quickly forcibly suppressed by him, and he used his dragon power to raise his voice and shouted to all the dragon knights: "All the dragon knights of the Holy Forest Continent, if we don't fight to the death today, we will fight to the death!" I have already received news just now that the outsider has entered the cave where the Dragon King was killed, and the Dragon King has been seriously injured at this time. Just give him another half an hour at most, and he will be able to kill the Dragon King. When the time comes. These killing dragons will retreat without a fight. ”

"So, we must hold on to this last half hour, as long as we hold on. Victory is ours!"

Hearing this, the Xuandi Holy Envoy sighed secretly in his heart, and then forcibly suppressed the trace of despair, and also spoke: "The Killing Dragon King was seriously injured and had to hold out four light shields, which are its last barrier. And the outsider had already broken through two of them at this time. In just half an hour, he was able to break through the last two. When the time comes, it will be the time of death to kill the Dragon King. That is when we are victorious! Therefore, if we do not fight to the death, we must fight to the death!"

In the Holy City, as many as half a million dragon knights who were struggling to support the light mask heard this. Suddenly the spirit was shocked. The same voice roared from 500,000 throats: "If you don't fight to the death, you must fight to the death!" If you don't fight to the death, you must fight to the death!! If you don't fight to the death, you must fight to the death!!

Although Yu Hanshan also had a premonition in his heart, since the master said this, he would definitely not be false.

Unexpectedly, that outsider really became the savior of the Sacred Forest Continent. Thinking of this, a trace of unwillingness flashed in Yu Hanshan's heart. But there is nothing to be done.

But at this point, the most important thing. It's the current war.

"If you don't die in battle, you must fight to the death! If you don't die in battle, you must fight to the death!!If you don't die in battle, you must fight to the death!!"

For the first time in his life, Yu Hanshan roared so hard that he almost burst his throat.

500,000 dragon knights, the roar of which made the earth tremble and the heavens tremble.

When the overwhelming killing dragon heard this voice, the attack was even slowed down.

But the next moment, they attacked the light mask even more frantically.

Finally, at some point......

The mask suddenly shattered.

But neither side immediately stepped forward to fight, but both froze for a moment, as if not believing that it was true.

The next moment, suddenly, the sound of shouting and killing shook the sky, and the roars kept coming, like two flames crashing together, and the two sides started a fierce fight.

"Kill-" Yu Hanshan roared out of the spit, and there was a trace of blood red.

"Kill-" Uncle Qi, a rare middle-aged man in the Holy Dragon Continent who had experienced a hundred battles, also had a hint of hoarseness in his voice, and his eyes were bloodshot.

"Kill-" The voices of the Xuandi Holy Envoy and the Haodi Holy Envoy overshadowed the overwhelming shouts of killing, which shocked everyone's hearts.

The dragon knights of the entire Holy City did everything they could for their final battle.

In less than ten minutes, more than half a million killing dragons had been beheaded under the city. The two dragoon envoys went all out. This was the first time those dragoons had seen two dragoon envoys attack with all their might. As the two of them struck, one after another of the killing dragons fell from the sky. In ten minutes, the two of them killed as many as 100,000 killing dragons.

However, the losses of the dragon knights were also extremely heavy.

In less than ten minutes, more than 50,000 dragon knights had already been killed. This even includes thousands of dragoons and more than twenty dragoons.

However, even so, they still fought to the death, because they believed that there was an outsider on the Dragon Isle who was fighting the Dragon Killer and was about to kill the Dragon King.

At this time, the Xuandi Holy Envoy completely used all their strength. Because they know that if they don't show all their strength this time, I'm afraid they won't have a chance in the future. Although with the strength of the two of them, they can completely escape. But in that case, only the two of them will be left, and when the time comes, the Killing Dragon King will come after him with hundreds of millions of killing dragons, and they will still have no escape.

At the same time, hundreds of thousands of miles away, on the Demon Dragon Island, in the Demon Dragon Cave.

Xue Yi was sitting there cross-legged, breathing the dragon power in his body, and with the help of Yuan Li, the chaotic dragon power in his body quickly smoothed out.

He opened his eyes and looked at the Ultimate Killer and the Shroud. This light mask exudes extremely rich various attributes, and with the strength of his own Dragoon King, he can't break it at all.

Even if he was extremely familiar with various attributes, coupled with the power of the Heavenly Hammer, it was impossible to break it in a short period of time.

And the body of the Killing Dragon King is recovering rapidly, even if he finally breaks it, once the Killing Dragon King recovers, it will be too difficult to kill the Killing Dragon King again at that time.

Liao Cheng saw that Xue Yi's face was not as pale as just now, and knew that Xue Yi's body had improved a lot, so he asked, "What should I do? This light mask? As far as I know, this light mask is extremely hard, plus the four attributes are mixed together, no matter which attribute is used to attack, it will be bounced back." In addition, it is isolated from all spatial movement, so it cannot be moved in by teleportation or the like. How are we going to kill it?"

Xue Yi sighed secretly, he knew what Liao Cheng said, and he also knew that his dragon control technique would not work in front of this ultimate killing dragon king.

This Ultimate Killing King is too strong, and even if it is seriously injured, it is too difficult to kill it.

At this moment, Xue Yi's heart suddenly moved, and he asked Liao Cheng: "Do you have that kind of formation that has an amplification of the soul?"

Liao Cheng thought for a while and said, "Yes, yes, but that needs to be guided by the four blood crystals, I only have wind blood crystals here, so ......"

Xue Yi had a smile on the corner of his mouth and said, "That...... I brought out all the blood crystals of the Crystal Palace, including thunder, fire, water, and wind, you won't blame me, will you?"

When Liao Cheng heard Xue Yi's words, his face showed a look of reminiscence, and after a while, he said, "The people in the Crystal Palace are no longer there, what is the use of wanting this blood crystal?"

After speaking, Liao Chengcheng had already started to arrange the formation, and he used a very sharp carving knife to engrave some patterns on the ground that Xue Yi had never seen before, and said: "This formation is the energy that bursts out through the blood crystals of the four systems of thunder, fire, water and wind, increasing the strength of a person's soul in a short period of time. But it's less than three minutes, so you have to get it right. ”

Xue Yi nodded: "No problem." ”

Soon, Liao Chengcheng had been portrayed into a formation.

This formation is octagonal, with a diamond-shaped groove on each of the eight corners.

Xue Yi naturally knew that these diamond-shaped grooves were the grooves for bloodletting crystals, but he didn't know exactly how to put them.

"Thunder, fire, water, and wind take two each. Liao Cheng said to Xue Yi.

Xue Yi took out the blood crystals of the four series as he said.

Liao Cheng took it over, first put a thunder-type blood crystal in a groove, and then put a fire-type one in the groove next to it, followed by a water system, and a wind system. After the wind system is finished, it is the thunder system, the fire system, the water system, and the wind system.

With eight blood crystals, just eight grooves were placed.

After Liao Cheng finished doing this, he showed a satisfied look on his face, and said to Xue Yi: "Okay, it's all done, now you stand in the formation, and I will activate the formation." ”

Xue Yi immediately took two steps forward and entered the formation.

At this time, Liao Cheng injected the dragon power of the wind system into one of the wind blood crystals. I saw that the blood crystal immediately emitted a transparent light. Then, the wind dragon power flowed along a line in the pattern towards the lightning system next to it. The moment it touched the thunder blood crystal, the thunder blood crystal also emitted purple light, and at the same time, a thunder dragon power flowed out of the blood crystal, flowing towards the fire system next to it.

In this way, in a matter of moments, the entire formation formed a cycle.

At the same time, Xue Yi could feel that the four-line dragon power entered his body from the soles of his feet. But this is not an ordinary dragon power, nor is it the Yuan power that he has fused with the four systems, but a very special power that Xue Yi has never encountered.

This power entered his body, and Xue Yi only felt that his soul had become stronger in a moment, and it was growing at an extremely fast speed.

Double, double, triple......

In just half a minute, Xue Yi's soul reached more than thirty times the terrifying amount.

At this point, it stopped. And the eight blood crystals in the formation were all turned into powder because of the exhausted energy.

"Quick. Liao Cheng said.

At this moment, Xue Yi's huge golden soul that was more than thirty times more than thirty times moved. He carved a dragon harness pattern directly into the air, and then sent it directly into the light mask.

"Whether it succeeds or not, it depends on this time. Xue Yi's eyes flashed and he said. (To be continued......)
