Xue Yi was refining the mist, and the purple electric Tyrannosaurus rex and skeletal dragon in the outside world were not idle.

The Skeleton Dragon knew a lot about herbs, and in its opinion, the entire grassland was full of some precious herbs. For example, the fire spirit grass and thunder line grass that the waiter needs, and the fire spirit grass and thunder spirit grass that the dragon jockey needs, this kind of herb is very rare in the outside world, but when you get here, you may accidentally step on one of them if you walk a few steps. Even the rare herbs such as the Fire Essence Flower and the Thunder Essence Flower that the Dragoon Envoy needed for the rank can be found everywhere here, and they are all very old and have very good results.

After reaching the Dragoon Rank, there are not many herbs such as Fire Essence Flowers, but this herb is extremely rare. On the entire continent, there are only ten plants at most every year, and the dozen or so plants need to be supplied to more than thirty dragoons to improve their strength, and the supply is simply in short supply.

Therefore, the improvement of the strength of the dragoon is very slow.

Thinking about that Lei Yu Nandou at the beginning, for more than thirty years before the retreat, the entire Yanlong Empire Imperial Family had been helping him collect Lei Su Flowers, so he could concentrate on cultivation during the thirty years of retreat, and he didn't have to go out to find Lei Su Flowers.

And ordinary dragoons can't have such conditions at all.

Therefore, in the past ten years, few of the more than 30 dragoons on the mainland have been upgraded. It took Lei Yu Nandou to be promoted from a high-level dragoon to a super dragoon, and it took thirty years.

It can be seen that the importance of this type of herb is to the Dragoon.

And now, the skeleton dragon casually glanced at it. There is one Lei Su Flower to find, as long as fifty Lei Su Flowers, it is enough for the Purple Electric Tyrannosaurus Rex to use after Xue Yi reaches the Dragon Rider.

It took only two days. I found more than 50 plants. However, the purple electric Tyrannosaurus rex still continued to dig for the Rasu flower, and its reason was that he was a two-headed dragon, and naturally needed twice as many herbs as ordinary dragons.

So it took another five days to dig up hundreds of Lei Su flowers, and then it was satisfied.

And in the following time, the purple electric Tyrannosaurus Rex and the Skeletal Dragon continued to explore this ancient battlefield. They flew around the ancient battlefield a few times and found that this ancient battlefield reached the Thunder Emperor Mountain in the east. To the west is Shuidi Mountain, to the south is Huodi Mountain, and to the north is Fengdi Mountain. The radius is more than fifty miles. More than fifty miles away, there seemed to be something blocking them, and although they could see that there were still mountains fifty miles away, they could not fly through them at all.

Every time they want to cross the Four Emperors Mountain. There was an invisible barrier that kept them in the way. It is impossible to fly over the Four Emperors Mountain at all.

After thinking about it, the skeleton dragon came to the conclusion that these four sides should be sealed by the Wind Emperor.

Unable to break through those seals, he could only fly around over the grassland, and the purple electric Tyrannosaurus rex began to get bored again. Out of boredom, he proposes to go head-to-head with the Skeleton Dragon as a way to improve his combat skills.

The skeletal dragon readily agreed.

However, because the skeleton dragon has no body, only a skeleton, its combat power is far inferior to the purple electric Tyrannosaurus rex with two heads. Almost every battle is a pure abuse of the Purple Electric Tyrannosaurus Rex against the Skull Dragon.

Whenever this happens. The Ice Dragon will then step forward and slap the Purple Electric Tyrannosaurus Rex to the ground with one wing.

But in the midst of such grinding. The Purple Electric Tyrannosaurus Rex's resistance and combat skills are growing rapidly. After three months like this, the fighting skills of the purple electric Tyrannosaurus rex are absolutely invincible among the young dragons, and even compared to some adult dragons, they can barely fight.

......

At the same time, in the blood-colored space, Xue Yi's devouring continued.

Now he devoured the black mist extremely fast, and in just a few minutes, he could completely swallow hundreds of cubic meters of black mist.

At this time, the huge black fog was already one-fifth smaller than the original.

The huge black mist finally felt the crisis at this time, and it kept trying to escape from Xue Yi, fleeing faster and faster into the distance.

But its speed is not as fast as Xue Yi's teleportation, Xue Yi always catches up with the black mist, and then differentiates a part of it to absorb it.

This made the huge black mist angry but helpless. Whenever a piece of black mist was swallowed by Xue Yi, there was always an angry roar in the center of that huge black mist. However, it was just a roar, and it did not pose a threat to Xue Yi in the slightest.

In the blink of an eye, two months have passed. At this time, Xue Yi's soul had reached a height of more than three hundred meters, standing in the blood-colored space, like a huge blue giant.

On the opposite side of Xue Yi, the black mist was only half the size of its original size.

However, even if it was one-half, it was thousands of times larger than Xue Yi's current soul body. After all, this is the union of the souls of more than five million people.

......

In the blood-colored space, the years have passed in a hurry, and before you know it, it has been more than a year.

At this time, Xue Yi's soul body had already become a blue giant with a height of thousands of meters, and there was a faint sound of wind and thunder between the swallows.

On the opposite side of him, the black mist was only one percent of the original, more than ten times larger than Xue Yi.

The Shaking Sea Aya in Xue Yi's hand continued to grow as his soul grew. At this time, the shaking sea is 10,000 meters long. The green light on it is rippling, and it looks very good.

With the strength of Xue Yi's soul at this time, it was easy to control Shaking Hai Aya. With a random wave, ten thousand rays of light shook down on the Shaking Sea Silk, and his soul controlled the ten thousand rays of light, connecting them into a ball of light with a diameter of 10,000 meters, wrapping the remaining black mist in the blood-colored space.

The black mist struggled to escape, but as soon as it touched the light of the shaking sea aya, it immediately dissipated.

Although it is said that running away is death, and not escaping is death, but not escaping is always a little slower than escaping to death, so these black fogs can only shrink in the ball of light, and dare not touch the ball of light for half a minute.

As soon as Xue Yi, who was thousands of meters high, opened his mouth and inhaled, the black mist in the ball of light was sucked into his mouth.

As soon as those black mist entered Xue Yi's mouth, they were quickly refined and absorbed by him, and in less than five minutes, that huge black mist was actually absorbed by Xue Yi nine times out of ten. Only the last black fog with a diameter of about 100 meters remained, still resisting stubbornly.

Xue Yi smiled coldly and sped up refining.

But after a while, he was surprised in his heart, no matter how powerful his soul was, the black mist was still the same black mist in front of him, and there was no intention of being refined at all.

Xue Yi was surprised, opened his mouth and spit out the black mist with a diameter of 100 meters, and then wrapped the black mist with the entire Shaking Sea Aya.

Although this black fog is more tenacious than the original black fog, it is also dissipating at a speed visible to the naked eye under the wrapping of Shaking Sea Aya.

Five minutes later, the black mist was less than a meter in size.

Through the surface of the black mist, you can faintly see that in the center of the black mist, there is something that glows with golden light.

Xue Yi had doubts in his heart, urging the shaking sea to continue to melt the black mist.

Soon, the remaining black mist was also completely refined, and at this time, the thing in the center of the black mist appeared.

It was a golden finger-sized spot of light.

Seeing this point of light, Xue Yi immediately recalled that at the beginning, on an island in the Sea of the Dragon God, a volcano erupted, and a golden egg appeared, and the golden egg later turned into a golden dragon, and the dragon finally turned into thousands of golden points of light and flew in all directions of the continent. And this golden point of light originally wanted to invade his body, but it was sealed in the sword body by the bloodthirsty sword.

At this time, the black mist around the golden point of light was all melted away, and the point of light seemed to be quite spiritual, and when he found that the situation was not good, he immediately let out a loud cry and flew towards the distance, extremely fast.

But at this moment, Xue Yi suddenly disappeared in place, and when he appeared, he was right in front of the point of light.

The point of light was too fast, and it crashed headlong into Xue Yi's mouth.

Of course, Xue Yi didn't swallow the golden point of light directly in his mouth, but first used the light of Shaking Sea Aya to form a ball of light around the point of light, wrapping it up, and then swallowing it in his mouth.

Although the point of light was also a little afraid of Shaking Sea Aya, the light of Shaking Sea Silk seemed to be much less threatening to it than the black mist. It was constantly rushing through the ball of light, trying to break through it.

But Xue Yi controlled the ball of light with his soul, and wherever it wanted to break through, Xue Yi would thicken the ball of light there, so that it couldn't rush out at all.

Then Xue Yi controlled the ball of light to slowly shrink, compressing the space where the golden point of light moved. In this way, the golden point of light wanted to rush out even more frantically, but Xue Yi had already placed another ball of light around the ball of light, and the two layers of ball of light blocked, the golden point of light could not rush out at all.

Finally, when the ball of light gradually shrank to the size of a fist, the golden point of light could no longer move for half a minute, and when it was about to be completely engulfed by the ball of light, suddenly, from the point of light, a huge human head phantom appeared.

This phantom was a hundred meters in diameter, and as soon as he appeared, he stared at Xue Yi coldly, and threatened angrily: "If you kill me today, he will definitely take revenge one day!"

Although Xue Yi was surprised that this golden point of light could turn into a human head phantom, he directly ignored this threat and directed the ball of light to continue to compress. Soon, the phantom of the human head disappeared with a scream, and turned into a golden point of light again.

Then the golden point of light was completely engulfed by the ball of light.

Ten minutes later, Xue Yi withdrew the ball of light, only to see that what appeared in front of him was still a golden point of light. It's just that this golden point of light is motionless, and compared to the crazy and hideous point of light just now, this point of light seems extremely calm.

Xue Yi secretly thought to himself, this golden point of light should have been a trace of soul imprint from someone's soul. And now after the washing of the light of the shaking sea aya, the trace of the soul left by the person has disappeared, and now this golden point of light is the soul of the ownerless.

This small golden point of light before can drive the ghosts of tens of millions of people, which shows how powerful this point of light is.

Thinking of this, Xue Yi's heart couldn't help but flutter. (To be continued......)
