Xue Yi and Liao Cheng flew all the way towards the Demon Dragon Sea. On the way, he encountered several groups of killing dragons, Xue Yi didn't fight with them at all, they all relied on the speed of the Wind Dragon in a flash, although those killing dragons were also very fast, but when they were on the ground, they could be very fast with their strong tentacles, and when they were in the air, their speed was much slower, and it was naturally impossible for them to catch up with Xue Yi.

The farther away you are from the Holy City, the fewer you will encounter the Killing Dragons. After a day, they had rarely encountered a group of killing dragons. Their flight was much smoother along the way.

What they saw along the way was still the same as what they saw on the way to the Holy City, all the land that had been slaughtered by the dragons.

In the boring flight, Xue Yi asked Liao Cheng: "When I teleported back from the Holy City that day, the pattern in your hand could form a vortex, this should also be a formation, right?"

"That's right, it's a small devouring array that can swallow up something around it, but I've made a slight alteration so that it only devours light. Liao Cheng said.

Xue Yi said: "It's amazing. ”

As soon as Liao Cheng mentioned the formation, the whole person immediately came to his senses and said, "You also think the formation is amazing, right? You are exactly the same as what my master said at the beginning." In our Killing Continent, very few people studied the formation, and they all thought that it was a sideshow. However, when my master saw it, he encouraged me to continue my research, and even took out the book on the formation in the library to show me. I've been researching it for more than 30 years, and that's only a little bit of a success. However, the more I studied, the more magical this formation became, and what I knew was only the tip of the iceberg. ”

"For example, I teleported your teleportation array twice. There are many kinds, but the one that was originally set up in the Crystal Palace took me a few days to set up. Therefore, it has the function of defending against counterattacks. And the teleportation array on the teleportation jade pendant for you, because the pattern is too small, can only be simply depicted, so there is no other function, just teleportation. ”

......

Liao Cheng didn't have many words, but when he mentioned the formation, he gushed endlessly. Xue Yi only occasionally raised a doubt. Liao Cheng can say a lot of words, so that Xue Yi can understand clearly.

The more Xue Yi listened, the more magical this formation became. He felt like he was a step behind. This ring is the formation.

In the Holy Dragon Continent, no one studied the formation at all, so Xue Yi didn't study it. But after hearing Liao Cheng's introduction at this time, Xue Yi also moved his mind to learn the formation. It's just that the time is too short. Even if you learn it, you won't learn much.

Liao Cheng said to Xue Yi very enthusiastically: "If you want to learn." I'll teach you, the two of us study the formation together. ”

So in the next few days, Liao Chengcheng told Xue Yi a lot of formation principles.

It turns out that this formation is to carve some patterns that can communicate the power of the elements, and then inject dragon power into it to activate the formation. In this way, the formation can produce a variety of different effects.

Liao Cheng told Xue Yi a few simple teleportation arrays again, and asked Xue Yi to try to portray them.

Xue Yi has an extremely strong soul strength, and it is easy to master these patterns. After less than ten attempts, he successfully mastered several formations.

But it was short-lived. He couldn't have learned more.

Five days later, they had seen the Demon Dragon Sea from afar. Xue Yi did not hesitate and urged the Wind Dragon to fly directly towards the Demon Dragon Sea.

The Demon Dragon Sea was not a place where a group of demons gathered as Xue Yi imagined, on the contrary, it seemed to be calm here. The sea is blue, the sky is blue, and there are seabirds flying in the sky from time to time, and everything seems so quiet and peaceful.

Xue Yi's soul swept out, and within a range of millions of miles, it was all this scene.

Liao Cheng said to Xue Yi: "This is just the exterior of the Demon Dragon Sea, the Demon Dragon Island is in the middle of the Demon Dragon Sea, and what you see there will be completely different from here. ”

While the two were talking, a black cloud suddenly appeared in the sky. With Xue Yi's eyesight, it was easy to see that it was not a black cloud, but a huge group of killing dragons.

Xue Yi saw this group of killing dragons and said to Liao Cheng: "It should be that there is movement over there in the Holy City, and the Killing Dragon King sent reinforcements to support." The Holy Envoy of Xuandi said that they were there to attract the attention of the Killing Dragon King, and our side tried to move forward as carefully as possible to kill the Killing Dragon King. ”

"Then we must not be discovered by these Killing Dragons now, once we fight with them, we will definitely be known by the Killing Dragon King. Liao Cheng said.

Before Liao Cheng's words fell, a cloud of transparent energy appeared in Xue Yi's hand, enveloping him, Liao Cheng, and the entire Wind Dragon.

The next moment, they all disappeared.

Soon, the group of killing dragons flew past where they had just been, disappearing into the sky behind them.

It was only at this point that the Wind Dragon reappeared.

Liao Cheng looked at Xue Yi in surprise, but he didn't expect that in addition to Xue Yi's powerful lethality, he also had a good set of hiding figures.

Xue Yi said to Liao Cheng: "Let's go, we have to do it as soon as possible, while there is a move on the side of the Holy City, the attention of the Dragon King is over there." ”

So Xue Yi and Liao Cheng kept their flight altitude as low as possible and flew forward quickly against the sea. On the surface of the sea, a white wave rolled up, stretching behind them.

Let's say that not long after Xue Yi left the Holy City, the Xuandi Holy Envoy and the Haodi Holy Envoy jointly issued an order, and all the dragon knights above the dragon rider king level all went out of the city and concentrated their forces to break through a little outside the city. Moreover, the Holy Envoy of Xuandi personally led a team of hundreds of people and rushed towards the east gate of the Holy City.

With the dragon rider holy envoy leading the team, those dragon rider venerables and dragon rider kings were also in high spirits, fighting bravely to kill the enemy, and in just a moment, they killed tens of thousands of killing dragons.

But the killing dragons seemed to be endless, and the killing dragons in all directions all surrounded the east gate, so that the dragon knights led by the Xuandi Holy Envoy were a little unable to support it.

But at this moment, at the west gate, the Haodi Holy Envoy came out with hundreds of people. And since the killing dragon at the west gate has mobilized two-thirds to support the east gate, the defenses here are much weaker. was killed by the Holy Envoy of Haodi.

In this way, the killing dragon at the east gate saw this and wanted to return to the west gate, but the Xuandi Holy Envoy led people to charge.

The slaying dragons were so stumbling that they eventually had to retreat fifty miles, far away from the Holy City. At the same time, a signal for help was sent to the Demon Dragon Island, and the Killing Dragon King of the Demon Dragon Island finally sent a million Killing Dragons to support.

Of course, the Xuandi Holy Envoy and the Haodi Holy Envoy did not take the opportunity to kill them. After all, if you don't go out, there is still a holy city here that can be used as a barrier, and there are many mechanisms in the holy city, if the killing dragons want to attack the city, the mechanism will be opened, and it will last at least a month or two.

But if they escaped, without the barrier of the Holy City, it would be much easier for the Killing Dragon to kill them.

Therefore, the Xuandi Holy Envoy and the Haodi Holy Envoy were just feints to attract attention and buy time for Xue Yi.

Let's say that Xue Yi and Liao Cheng flew at sea for more than ten days, during which the killing dragons that were as gray as one million flew in the direction of the Holy City twice.

"Looks like we're going to get it soon. Xue Yi said, urging the Wind Dragon to fly forward.

After flying for another three days, they finally saw in the distance that there was an extremely large island entrenched in the sea. With Xue Yi's eyesight, he could easily see that on that island, there were circles of killing dragons guarding it.

Liao Cheng saw that those killing dragons were in a ring defense, his face suddenly sank, and he said, "It's not the right time for us to come. ”

"What?" asked Xue Yi.

"Generally speaking, the Killing Dragon Group has a ring defense, which can only indicate one point, the Killing Dragon King is about to lay eggs. ”

Xue Yi remembered the scene of the killing dragon's lair in the underground last time, and said suspiciously: "But the killing dragon group last time didn't form a ring defense." ”

"Last time, the Killing Dragon King had already laid eggs, and even hatched young dragons, so his defense was naturally not as strong as it is now. It seems that our task this time will be even more difficult. Liao Cheng said.

Xue Yi thought for a while, but shook his head and said: "If you look at it from another aspect, the Killing Dragon King is about to lay eggs, and its attack and defense will be reduced, as long as we can break through the heavy defenses outside, then the chance of killing the Dragon King should be greater." ”

Hearing this, Liao Cheng turned his head and looked at Xue Yi in surprise, and after a moment, his eyes flashed: "Yes, as long as we can break through the outer defenses and face the killing dragon, then this should be the best time to kill it." ”

So Xue Yi used micro-level energy to hide his body, and then urged the killing dragon to fly towards the Demon Dragon Island.

Along the way, Liao Cheng experienced the wonder of hiding his body many times, and he asked Xue Yi when he was invisible: "What are you ...... What kind of energy is it?"

Xue Yi said: "Micro-level energy. Then he smiled and looked at Liao Cheng who was invisible.

In stealth, all they could see each other was a vague outline, as if they were in a fog.

"I'll teach you when I have time. Xue Yi said.

Liao Cheng's voice was a little excited: "If you can use this energy in the formation, then the formation can be invisible and will not be noticed." If you turn it on when you need it, it will definitely surprise everyone. ”

Xue Yi laughed secretly, this Liao Cheng, anything can be pulled by him to the formation, he really deserves to be a formation maniac.

However, Liao Cheng's idea is very good, if he can really use the micro-level energy in the formation, the effect will definitely be very different.

But this was not the time to think about this, they had already come to the outermost group of killing dragons not far away.

This group of killing dragons can almost encircle the entire huge island from the sky to the ground.

Seeing this, Liao Cheng frowned and said, "The distance between this killing dragon group is too close, even if we are in a stealth state, it is very likely that they will inadvertently touch it." ”

Xue Yi smiled indifferently and said, "It's not in the way." With that, the two of them and the Wind Dragon disappeared in an instant, and the next time they appeared, they were already behind the Killing Dragons. (To be continued......)
