Liao Cheng saw the dense group of killing dragons surrounding Demon Dragon Island, frowned slightly, and said, "I'm afraid it will be difficult for us to break through." ”

Xue Yi smiled indifferently and said, "It's not in the way." ”

Before the words fell, they had already disappeared, and the next time they appeared, they had already appeared inside the huge encirclement, behind the killing dragon.

"Teleportation!" Liao Cheng said in surprise, "Very rare skill." ”

Xue Yi didn't say anything, but urged the Wind Dragon to continue to fly towards the center of the island. He could already feel it at this time, and there was an extremely powerful aura there. This kind of aura is not even much worse than the Xuandi Holy Envoy and the Haodi Holy Envoy.

Xue Yi felt a pang in his heart, was the one he wanted to kill such a powerful opponent?

If you really face such a strong opponent, I am afraid that you have no chance of winning.

But soon, Xue Yi suppressed such thoughts in his heart, after all, he had defeated opponents who were stronger than himself many times. And this time, the opponent is just a little too tough. As long as you are cautious and observant, you will definitely be able to find its flaws and kill it in one fell swoop.

Liao Cheng said to Xue Yi at this time: "Now that the sky is full of killing dragons, and the defenses on the ground can be loosened a little, let's go from below, through the underground killing dragon passage, and reach the highest peak in the center of the island." That's where the dragon king was killed. ”

Xue Yi nodded and said, "Just as you say." ”

After all, Liao Cheng had been here once, so he was not very familiar with the terrain here. At the very least, you know where to go and where not to go.

The two jumped off the Wind Dragon, and Xue Yi put the Wind Dragon into the space, and the two were still invisible. Walk into the forest.

It sounds like a dense forest, but in fact, all that remains is a section of charred wooden stakes. The killing dragons are all fire-based, and they stay here all year round, and this place is naturally often covered in flames.

They made their way through the stakes, and they encountered no obstacles along the way, except to dodge the swarms of dragon-slayers. After all, this is the Demon Dragon Island, a place where the killing dragons gather. The animals of the island have been eaten by the slaying dragons long ago. There was no food.

In desperation, they left the Dragon Island and went to the outside world in search of food. But it was resisted by the dragon knights. Thereupon. A war between humans and slaying dragons for food and resources begins.

From time to time, the two of them dodged the Killing Dragons, and none of the Killing Dragons could spot them. However, Liao Cheng's words made Xue Yi's heart tighten.

Liao Cheng asked as he walked: "It stands to reason that any skill has a duration, but the length is different. Your stealth skill. How long will it last?"

Xue Yi frowned. said, "Twenty minutes." ”

"That is to say, within twenty minutes, we will walk to the bottom of the mountain peak a hundred miles away and enter the cave, so that we will not be discovered by the killing dragon. But we're probably ...... speed now."

Before Liao Cheng finished speaking, Xue Yi grabbed Xue Yi with one hand, and the micro-level energy under his feet rose, and with Liao Cheng, he rushed towards the mountain peak like flying.

Liao Cheng was taken aback. He didn't expect people to be so fast when they were running on the ground. I could only hear the wind whirring in my ears, and the stumps on both sides swept backwards at a great speed. The speed of the two of them has reached the extreme.

Although Liao Cheng has learned how to be fast. But that's just jumping and changing direction for a short distance, and you can't run long distances at full speed. At this time, seeing Xue Yi's speed, he would naturally be surprised.

Soon, twenty minutes had arrived, and they were relieved when they rushed into the cave at the foot of the mountain.

At this time, the figures of the two gradually appeared.

"We really ran hundreds of miles in twenty minutes!" Liao Cheng exclaimed.

"That's nature, otherwise wouldn't we be exposed under the noses of the slaying dragon now?" As he spoke, Xue Yi's soul probed around. Soon, he surveyed the entire mountain.

I saw that this mountain peak is more than 8,000 meters high, and in the belly of the mountain, there are countless holes to communicate with each other. This is supposed to be where the Killing Dragon King hatches his eggs. It's just that the eggs haven't been laid yet, so the walls won't jump out of the walls to kill the baby dragons like they did in the underground lair.

From the air, Xue Yi could feel a very strong four-series element, and these four-series elements were very balanced. This made Xue Yi very surprised.

Generally speaking, there are four series of elements in the air, but these four elements are not balanced, often one is many, and the other is few. Basically, there is no other place like here, where the four elements are so balanced. This level is already about the same as the balance of the power of the four dragons in his body.

It seems that the two holy envoys said that this killing dragon king is a whole dragon, and this is indeed true.

Only a full line of dragons can balance the elements in the air here to such an extent.

After observing for a while, Xue Yi and Liao Cheng walked along the cave. Xue Yi secretly took out the map, swept his gaze, and saw that the teleportation array was more than twenty miles away from the top of the mountain. In other words, on the other side of the mountain, he had to follow the cave to the very center of the cave, and then pass through the other side, in a hidden place at the foot of the mountain, where he could find the teleportation array.

The two of them walked along the cave, which was winding and extremely difficult to navigate. There are also numerous forks in the road. Xue Yi admired Liao Cheng's memory. He had been here with his master once more than thirty years ago, and he still remembers it so clearly that he could distinguish the passage of progress among the countless forks in the road. This has to be admired.

On several occasions, they both saw a slaying dragon guarding the dark cavern ahead.

Liao Cheng said: "We can't kill these killing dragons, once we kill them, if the smell of blood is smelled by the killing dragon king, he will definitely know that someone has invaded." ”

Xue Yi smiled indifferently and said, "This is easy to do." As he spoke, he had already disappeared in place with Liao Cheng, and when he appeared, he was already behind the killing dragon.

The dragon slaying guards didn't even notice them.

The farther you go in, the fewer guards you will encounter, and the faster they will go.

"It stands to reason that the closer you get to the Killing Dragon King, the more guards there should be, why are there fewer guards here?" Xue Yi asked puzzled.

Liao Cheng replied in a low voice as he walked forward: "This is a habit of killing the Dragon King, every time when laying eggs, only guards are arranged around the nest, and the closer it is, the fewer guards there are. This is to maintain a better environment for spawning. ”

After walking for more than ten minutes, the two of them did not encounter a single guard, and their speed became faster, and in only twenty minutes, they came to the entrance of the cave.

Here, as they had seen before, was an extremely large cave. It's just that this cave is more than ten times bigger than the previous one.

And in the middle of this cave, there is a huge pool. The diameter of this waterhole reaches tens of thousands of meters. Strangely, the water in this pool is divided into four colors, red, purple, green and transparent.

Above the pool water, there are four series of elements that are extremely rich.

The intensity of that element was enough for a Dragoon Apprentice to ascend to the level of Dragoon within ten years.

"The last time I visited, there wasn't a waterhole. Liao Cheng said in surprise.

Before he could finish his words, suddenly, from the pool, a long snake suddenly burst out, bringing countless splashes.

In fact, this is not a long snake, but a tentacle on the body of the killing dragon king.

The diameter of this tentacle was more than a meter thick, and the length was more than a hundred meters, which was thicker and longer than the tentacles of any killing dragon that Xue Yi had seen before.

This tentacle felt a cave on the wall of the cave as if it had eyes, and then at the top of the tentacle, there was a wriggling, and three green spherical objects with a diameter of one meter were discharged by it, and the cave kept rolling in.

"It's laying eggs!" Liao said, "Most of the caves around it are empty, indicating that it has just begun to lay eggs." And this spawning process has to last at least four or five days. And on the third and fourth days, when it is at its weakest, we can attack again. The odds will be greater. ”

Xue Yi didn't say anything, so he naturally agreed to this plan. After all, although the Killing Dragon King did not surface, you can judge how powerful it is from that tentacle. To attack it now is to seek death.

However, Xue Yi quickly thought of a question: "Those three eggs are all green?"

When Liao Cheng heard this, he immediately reacted: "The killing dragons I saw before were all fire dragons, and there have never been other killing dragons, this is ...... It's adapting to the environment. When there were too many fire-based dragons and too little food, it began to give birth to water-based killing dragons. In this way, the killing will probably be able to forage in the water. The area of the Killing Continent Ocean is huge, so they won't be short of food!"

Speaking of this, both of them were a little frightened.

This slaying dragon is not only powerful and intelligent, but also terrifying in its adaptability. With such a killing dragon, it is no wonder that all the dragon knights of the Killing Continent will be driven into the Holy City, I am afraid that the Holy City is also in danger at this time.

After diving into the water for a moment, the tentacle reached out again, found another small cave in the cave wall, and laid three green eggs.

Xue Yi and Liao Cheng were secretly waiting, waiting for the moment when the Dragon King would be weak two days later.

Meanwhile, in the Holy City, a great war is about to unfold. And this war will be an extremely tragic one, and it will be a time for mankind to fight for its last home.

If it can't be held this time, then not only the Holy City will be finished, but the entire Killing Continent will be finished. At that time, the humans who killed the continent would be in danger of extinction. (To be continued......)
