Xue Yi saw that Liao Cheng had spent more than half an hour in front of this ancient teleportation array, but he still failed to find the eye of the array to open the teleportation array.

His heart moved, and his body was immediately wrapped in a layer of faint micro-level energy, and he slowly walked towards the stone wall. Then reach out and touch it gently.

Suddenly, his right hand sank into the stone wall.

The next moment, as soon as Xue Yi raised his feet and took a step, the whole person disappeared into the stone wall and disappeared.

The light of thought in Liao Cheng's eyes was suddenly swept away, and he was replaced by extreme surprise.

"How...... How is it possible? No need to open the teleportation array? No need to look for the array eye...... Just walked over by yourself?"

In extreme surprise, Liao Cheng also walked forward.

Bang -

With a muffled sound, Liao Cheng hit the stone wall directly. Although with the strength of his body, he would not break his head, but it also made him feel a lot of pain.

At this moment, the stone wall squirmed, and there was a ripple like a ripple of water, and Xue Yi walked back from inside.

Liao Cheng was even more surprised: "Is this okay?"

Xue Yi smiled indifferently: "It's nothing, it's all the credit of micro-level strength." ”

"Micro-power? What's that?"

"It's a wonderful power, and if you master it, not only will you be greatly strengthened, but you will also master many wonderful skills. I'm directly penetrating the teleportation array, which is one of them. ”

As he spoke, Xue Yi pressed his hand on Liao Cheng's forehead, and used his soul to imprint all the contents of micro-level power and god-level power into Liao Cheng's soul without reservation.

When Xue Yi came to the Killing Continent, he could be regarded as coming to a foreign country. There was a sense of loneliness in my heart. And Liao Cheng was the only friend he knew in the Killing Continent, so he taught Liao Cheng micro-level power and god-level power without reservation.

Liao Cheng browsed it in his mind, and the more he looked at it, the more surprised he became: "It's amazing." It's amazing......"

After reading it, Liao Cheng retracted his mind and said to Xue Yi: "Come and don't be rude, since you gave me such a magical thing, I will also give you all my experience in the formation over the years." ”

As he spoke, he also pressed his hand on Xue Yi's forehead, sharing his decades of experience in studying formations, including the structure of some formations and the like. are all engraved in Xue Yi's soul.

His soul was not as strong as Xue Yi's, so it took a lot more time to engrave it than when Xue Yi engraved it for him.

After that's done. Liao Cheng's forehead was already slightly sweaty, he smiled bitterly and said, "Your soul is too strong, it is difficult to engrave. But it's okay. I've done it all. ”

Xue Yi immediately sank his mind into his mind and browsed all the experiences of that formation.

Xue Yi found that in Liao Cheng's memory, his earliest research on formation began with a book - "Heavenly Array".

In this "Heavenly Array", a completely different world is described, and that world has no dragon knights, and there are no such skills as these. Instead, there is a kind of person called a monk or something. This kind of person can harness the power of heaven and earth and achieve immortality. Live with heaven and earth, and shine with the sun and the moon.

Such a world made Xue Yi very curious and yearning for it.

But it's a pity that "Heavenly Array" mainly introduces formations, and rarely mentions other things.

Moreover, Xue Yi now has an important task, and he has no time to think about other worlds.

He continued to look down, and saw that in the heavenly array, there were many formations with various functions: teleportation array, trapped enemy array, killing array, offensive array, defensive array, amplification array, spirit gathering array, mountain protection array, and even resurrection array...... And so on and so forth.

It's a pity that this book is not a complete "Heavenly Array", but only a fragment of "Heavenly Array". Many of the formations recorded in it only have names, but no construction methods.

Xue Yi thought for a moment, but he couldn't think of anything, so he didn't think about it anymore. I just secretly said in my heart: If you still have a life after completing that mission, you must go to the monk's world to have a look.

Then Xue Yi looked at Liao Cheng's experience about the formation over the years, and he also had some understanding.

In the next few days, Xue Yi was waiting for the Dragon King to deal with the affairs of their clan, while exchanging his knowledge with Liao Cheng. He instructed Liao Cheng to learn micro-level energy, and Liao Cheng instructed him to learn formations.

Day 5.

Xue Yi carved a pattern on the ground, and then slowly, injected his dragon power into the pattern, and suddenly, the pattern emitted a faint yellow light. And above the pattern, a flame is born.

This is not a flame condensed from energy, but a real flame, exactly like the fire of nature.

Liao Cheng smiled happily: "I didn't expect that it only took you five days to master this rudimentary fire array. When I first started studying, it took me seven days. ”

Xue Yi smiled indifferently and said, "It's just the most basic, there are more formations waiting for me to learn later." ”

While the two were talking, a huge black cloud appeared in the sky.

Xue Yi raised his head and said, "It seems that the other Killing Dragons have returned, let's go, let's see what the Killing Dragon King will do with these Killing Dragons." How can their millions of slaying dragons survive if they don't compete with humans for resources? ”

Twenty miles away, they quickly walked and came to the top of the mountain peak of the Demon Dragon Cave.

The Ultimate Killing King had already laid its eggs, and its massive body was standing on top of the mountain peak, looking coldly at the bottom of the mountain peak.

Xue Yi and Liao Cheng stopped next to the Ultimate Killing King and looked at the ground below.

I saw that there, a fierce and brutal battle was going on inside the killing dragon. Above the clearing, the corpses of the slaying dragons had long since heaped up, and the ground had been corroded into one large pit after another, and there were terrible hissing sounds everywhere. Even Xue Yi couldn't help but be moved when he saw such a scene.

It turned out that in order to solve the problem of too many people, the Ultimate Killing King actually let the Killing Dragon King start fighting each other internally, and in the end, only 10,000 Killing Dragons could be left.

It sounds cruel, but it's a way for many creatures to keep their internal fighting power and sustainability.

In the blink of an eye, another five days passed, and among those killing dragons, the last 100,000 killing dragons were finally decided. And these killing dragons are the most powerful. They have been constantly fighting and have been tested many times, and they are the core combat power of the Killing Dragon.

At this time, the Ultimate Killing King finally ordered to stop the fighting, and then selected the strongest and uninjured Killing Dragon from among the 100,000 Killing Dragons. In the end, he put all the water-based killing dragon eggs it laid into the spatial ring.

These are all things that the Ultimate Killing King intends to take away.

Then, the Ultimate Killing King did one last thing for the Killing Dragons on Demon Dragon Island. It used up almost all the dragon power on its body, and on the entire Demon Dragon Island, four layers of dragon power light shields were arranged.

After the light shield was completed, the Ultimate Killing King became extremely weak again, and it said to the killing dragons, "In the future, as long as the light shield of this island is not broken, no human will be able to enter. And the resources on this island are enough for 90,000 killing dragons to survive. You have to control the number, and it must not exceed 100,000. As long as it doesn't exceed 100,000, you don't have to go outside the island to forage for food. As long as you don't leave the island, no human can hurt you, remember, remember!"

The slaying dragons all roared in unison.

The Ultimate Killing King finally glanced at the entire group of killing dragons, and then at Xue Yi.

Xue Yi's soul moved, and he included the Ultimate Killing King in the ring. Faintly, Xue Yi seemed to hear a sigh.

When the Ultimate Killing King entered the ring, Xue Yi found that the space of the ring had expanded to a radius of more than five hundred miles. Such a large space was enough for those 10,000 killing dragons to survive.

Moreover, this is still the time when the Killing Dragon King is at his weakest, and it is conceivable that after the Killing Dragon King recovers, the space in this ring will be further expanded.

After doing all this, Xue Yi said to Liao Cheng: "Let's go, we should all leave." ”

Liao Cheng glanced at the 90,000 killing dragons on the ground that were scattering in all directions, and a trace of melancholy rose faintly in his heart. Although he has only been with Xue Yi for a month, Xue Yi's personality has impressed him deeply. And Xue Yi is also a friend worth making.

He Liao Cheng has almost no friends on this continent, and now it is easy to have one, but he is about to leave so soon, how can this not make him sad?

Thinking of this, Liao Cheng took out a blood crystal and handed it to Xue Yi.

Xue Yi took it suspiciously, looked at the blood crystal, and saw that the blood crystal was different from the ordinary blood crystal, and on the blood crystal, there was an extremely complex pattern engraved on it. Above the pattern, there is a faint light that keeps flowing.

"This is a formation that I have spent more than ten years making, this array can trap the enemy, can kill the enemy, can defend, can also become a teleportation array, it all depends on the situation at the time. If you encounter an enemy who is 100 times stronger than you, you can trap them by crushing the Blood Crystal. If you encounter a large number of enemies that are less than 50 times stronger than you, you can kill all the enemies as long as you open the formation. Similarly, if you encounter a large number of enemies, or if you are too strong to open a teleportation array in a short period of time, you can use this array to defend and then use the teleportation function to escape. Liao Cheng explained.

Xue Yi looked at this formation in surprise and said, "This is the Heavenly Dragon Four Killing Array recorded in ......'s Heavenly Array! Isn't it incomplete......?

"It took me more than seven years to try to complete it, and then it took me more than two years to engrave it on the blood crystal. However, even so, it was still not as strong as the original Heavenly Dragon Four Killing Array. It is recorded in the "Heavenly Array" that this Tianlong Four Killing Array, killing immortals, killing Buddhas, killing gods, and killing ghosts, can be said to be the No. 1 killing array in Tianzi. But I barely made up for this, but I don't have the ability to do it. ”

"But this is already very powerful, but if you say that, if I have the chance, I really want to go to that different world and find clues to the Heavenly Array. ”

"Me too. Liao Cheng's eyes showed a look of yearning. (To be continued......)
