At this time, it was daytime, and it was still very calm in the ancient battlefield. Xue Yi sat on the ice and snow dragon, and in a moment, he flew over the entire grassland, and came to the mountain where the Thunder Emperor was.

This mountain is actually a huge statue, which Xue Yi had seen when he entered the ancient battlefield last time. Xue Yi came to the top of the statue, where there was a life-size golden statue, which was exactly the trace of the soul imprint of the Thunder Emperor Lei Yutian.

At this time, the golden statue was looking ahead, and there was a domineering attitude in its eyes.

Xue Yi faced the golden statue of Lei Yutian and bowed his head.

If it weren't for the Heavenly Hammer given to him by Lei Yutian, he would have died at the hands of Lei Yu Nandou.

Xue Yi had just finished worshipping, and on the statue of Lei Yutian, the layer of gold fell off like petals, and then a somewhat illusory-looking figure appeared in front of Xue Yi.

"How's it going?, is the Heavenly Hammer still usable?" asked Lei Yutian's Soul Mark.

Although Xue Yi was surprised in his heart, he was not too flustered, after all, he had seen this kind of situation last time.

He replied to Lei Yutian: "The predecessor's Heavenly Hammer is indeed the only holy weapon from ancient times to the present, and it is so powerful that it is rare in the world. ”

Lei Yutian laughed a few times, his laughter echoed throughout the ancient battlefield, and he said: "No matter how powerful it is, if it doesn't recognize you, you can't exert its power." It seems that it has taken you as its master. ”

Xue Yi was secretly happy in his heart, and was recognized by the holy weapon Heavenly Hammer, which means that he was recognized by the Heavenly Hammer. In this way, the combat effectiveness will inevitably increase greatly. Otherwise, it would be impossible to resist Lei Yu Nandou's attack.

Lei Yutian continued, "However, what you are using now is the power I left in the Heavenly Hammer. That kind of power, you can use it up to three times. With your current strength, after three uses. It's the best weapon for you. So what you need to do now is to increase your strength, and only when your strength reaches the level of a beginner dragoon can you exert a little power of the Heavenly Hammer. ”

Xue Yi listened and said, "I know this, I will go back to the ancient battlefield this time." I just want to retreat and practice and reach the level of dragoon. ”

Lei Yutian looked into the distance and seemed to be silent for a moment. Only then did he say: "The speed of retreat cultivation is too slow, and if you only want to cultivate to achieve stronger strength, it is easy to get into a dead end. When the time comes, you have to quit. But it's troublesome. ”

Xue Yi was so smart, when he heard this, he knew that Lei Yutian had something to say, and he immediately felt happy in his heart and asked, "What does the senior mean ......?"

Lei Yutian didn't seem to answer Xue Yi's words directly, but said slowly: "Back then, the strength of our four emperors reached the level of the Super Dragoon, but we didn't rest on our laurels and regarded the Super Dragoon as our limit, but continued to cultivate and enhance our strength. Decades later, I was the first to break through the Super Dragoon. Reached a higher level. I don't know if anyone has reached such heights before, and I don't know what to call this higher level, but in short, my strength has become extremely strong. ”

"Then the other three emperors also reached such heights in the decades after me. And we found that when the strength reaches this level, it will have a skill, that is, before dying, preserve part of its memory or core combat power. So the four of us preserved our memories and core combat power before we died. ”

When Xue Yi heard this, he was a little puzzled and asked, "Core combat power?"

"Core combat power, it can be said that it is the essence of our strength during our lifetime, as long as you obtain these core combat power, your strength will be qualitatively leaped, and your level will also increase. Lei Yutian explained.

Xue Yi hurriedly asked, "Then where are these core combat powers, and how can they be obtained?"

Lei Yutian smiled slightly, looked into the distance, and said: "In this ancient battlefield, the core combat power of the four emperors of thunder, fire, water, and wind are all here, and we used the core combat power of the four systems to suppress the dragon souls and ghosts in this ancient battlefield. Therefore, if you want to obtain core combat power, you must first subdue the dragon souls and ghosts here, otherwise, the core combat power will not be revealed, and you will not be able to obtain it. ”

Hearing this, Xue Yi looked at the nearly a thousand small hills in the ancient battlefield. There are so many dragon tombs, and there is a dragon soul in each of them, so many dragon souls, if you want the core combat power of the four emperors to suppress it, how can a little dragon jockey of yourself be able to subdue them? Moreover, if you have to add those thousands of ghosts, it is even more impossible.

Lei Yutian seemed to see through what Xue Yi was thinking, and said, "In fact, in the past tens of thousands of years, the core combat power of the four of us has been fighting against these dragon souls and ghosts. In the constant battle, the core combat power of the four of us is constantly being consumed, and those ghosts and dragon souls are also being consumed. Now they are far less powerful than they were back then, and their strength is not even one percent of that of the year. If you're confident and smart enough, it shouldn't be hard to subdue them. ”

When Xue Yi heard this, he thought to himself for a moment and said, "Okay, I'll try." ”

Lei Yutian looked at the resolute gaze between Xue Yi's eyebrows and said, "Very good, when you subdue the dragon soul and obtain the core combat power, it will be the day when your strength will improve by leaps and bounds." ”

After finishing speaking, Lei Yutian's phantom turned into that statue again, and the statue was motionless, as if everything just now was Xue Yi's imagination.

After a moment, Xue Yi turned around and sat there cross-legged facing the ancient battlefield. Secretly thinking about what to do next, in the face of thousands of dragon souls and thousands of human ghosts, it is difficult for him to retreat with his whole body, how to subdue them?

After thinking about it for a long time, Xue Yi didn't come up with any good way. Seeing that the red sun was slanting westward and the night was about to fall, Xue Yi secretly gritted his teeth, first try it, if it really doesn't work, then go back and think of other ways. Otherwise, if you keep sitting here thinking, you won't be able to accomplish anything.

When the last afterglow of the sky disappeared, and a moon like a jade disk rose from the sky, a black mist slowly rose from those hillocks on the grassland of the entire ancient battlefield.

Next to Xue Yi, the skeleton dragon was nothing, and the purple electric Tyrannosaurus rex saw those black mist rising, and immediately kept shaking its head and tail, waving its wings and claws, and constantly screaming in its mouth, which seemed to be extremely irritable.

The Ice Dragon was the first time it had seen the night of this ancient battlefield, and it saw the black mist rising up, roaring in confusion and madness.

Xue Yi straddled the back of the Ice and Snow Dragon, patted the back of the Ice and Snow Dragon, pointed to the dark red river that crossed the grassland in the middle of the grassland, and said, "Brother Bing, do you see it, take me to that river, after that, if you are not used to it, fly back to this mountain as soon as possible, those ghosts and dragon souls will not dare to attack this mountain." ”

Without saying a word, the ice dragon flapped its wings and flew towards the river on the ground. The Purple Electric Tyrannosaurus Rex and the Skeletal Dragon also followed the Ice Dragon.

When the ice dragon flew over, among the hillocks on the ground, black mist-like dragon souls continued to rise, flying towards the ice and snow dragon.

But the speed of the Ice Dragons was just as fast as those dragon souls, so they couldn't catch up with the Ice Dragons.

The Purple Electric Tyrannosaurus Rex has the ability to teleport, and every time a dragon soul wants to wrap it, the Purple Electric Tyrannosaurus Rex will instantly disappear, and then appear hundreds of meters away. Sometimes it even opens its mouth to bite those dragon souls, spewing thunder and lightning to attack those dragon souls. But those dragon souls are simply immune to its attacks.

And the strongest is the skeleton dragon. It was covered in flames and swaggered through the grassland, but when those dragon spirits saw it, they didn't pay attention to it as if they hadn't seen it.

When Xue Yi saw this, he couldn't help but be speechless.

He and the other two dragons worked hard to break through from the thousands of dragon souls, and the skeleton dragon directly flew slowly like shopping, but those dragon souls turned a blind eye to it, why is this gap so big?

Of course, Xue Yi thought about it for a while, but understood. In fact, the skeleton dragon is also a soul state, but it is attached to the keel. Strictly speaking, it is still a dragon soul, so those dragon souls naturally will not attack it.

At this time, the ice and snow dragon took Xue Yi and flew over the river.

Xue Yi's soul moved, and he took out a blood-red sword from the space of the ice and snow dragon. That's the Bloodthirsty Sword.

Then he jumped down and into the river. The Ice and Snow Dragon spewed out a breath of icy cold air, and the dragon souls that followed behind were all stagnant, and their speed slowed down a lot.

The Ice Dragon took this opportunity to swallow the dragon souls in one gulp, but when he swallowed them, those dragon souls were scattered like smoke. And when its body flashed, those dragon souls merged together again, and re-formed the appearance of dragon souls.

Seeing this, the ice and snow dragon did not keep attacking those dragon souls as irritable as the purple electric Tyrannosaurus rex, but turned his head and flew towards the mountain where Lei Yutian was. Behind it, the purple electric Tyrannosaurus Rex continued to attack those dragon souls, and at the same time, it was also attacked by those dragon souls, stumbling towards the Thunder Emperor Mountain.

Only the skeleton dragon, which was not attacked in any way, hovered above Xue Yi's head in case anything happened to Xue Yi.

At this time, Xue Yi jumped into the river, only to see that under the moonlight, the river water showed a transparent blood red.

This is not really a river, but a river of blood.

Xue Yi was not so surprised that he had seen this river of blood at the beginning.

When Xue Yi jumped into the river of blood, his soul poked out, only to see that within this river, it was densely packed with corpses and bones. Some of the corpses had already stood up when they saw Xue Yi coming here, and a terrifying smile came out of their mouths: "Hahahaha......"

A sneer also appeared on Xue Yi's face, and the bloodthirsty sword in his hand emitted a blood-red light. (To be continued......)
