In the sky above the plain, all kinds of dragon clouds gathered, and as far as the eye could see, there were hundreds, but most of them could not be absorbed by the dragon cloud jade Tianlin, and only the blue-purple thunder attribute dragon cloud would be attracted by him.

There are many blue dragon clouds, and there are also many purple dragon clouds, but the number of blue and purple dragon clouds is very rare, and Yu Tianlin has only absorbed about ten after walking around the plains for most of the day.

Every time he was penetrated by the blue-purple dragon cloud, Yu Tianlin's body strength would increase a little, and when the dragon cloud passed through his body, it would bring out a touch of gray, and he didn't know what it was.

And as the gray substance continued to leave the body, Yu Tianlin only felt that his whole body was getting more and more relaxed, and the whole person had an ethereal feeling.

Yu Tianlin didn't know what those gray things were at first, but with the changes in his body's senses, he faintly understood.

The gray substance brought out by the blue-purple dragon cloud is probably the impurities in his body.

You must know that in order to cultivate the dragon, the blue electric Tyrannosaurus rex martial soul must absorb the soul ring of the dragon species (true dragon) or the subdragon species (earth dragon) in order to obtain enough dragon power.

Among them, the ideal situation is naturally to absorb the soul ring of the dragon species, but the pure dragon species is too rare and very difficult to find, so the Blue Electric Overlord Sect can only retreat to the second best thing and attach the soul ring of the dragon species.

For example, the four soul rings on Yu Tianlin's body, three of which are from the lightning dragon, the thunder sound wave dragon, and the thunder brute dragon, although they all have the word "dragon" on their names, but unfortunately, they are all sub-dragon species, and the dragon power provided by the sub-dragon species is relatively low-level.

Therefore, Yu Tianlin has a large amount of low-level dragon power, and these low-level dragon power contains a lot of impurities, which lowers Yu Tianlin's quality in all aspects.

Because everyone in the Blue Electric Overlord Sect was like this, no one could detect this negative impact.

Of course, even if you notice it, it's useless, if you want to solve this problem, you must absorb the soul rings of the pure dragon species from the first soul ring to the ninth soul ring, and as long as one of the soul rings is from the subdragon species, it will be polluted by low-level dragon power, thus losing its purity.

Even if the predecessors of the sect who had entered the Dragon Valley before had been baptized by Long Yun, it would be useless to expel the impurities contained in the low-level dragon power in their bodies, because after they returned to the Douluo Continent, they would inevitably absorb the soul ring of the sub-dragon species.

There is no way, in order to become a dragon, you must absorb dragon power, but pure dragon species are too difficult to find.

Now, under the baptism of the blue-purple dragon cloud, the impurities contained in the low-level dragon power in Yu Tianlin's body are also constantly being discharged from the body, thus becoming more and more pure.

As his body felt more and more relaxed, Yu Tianlin also began to think.

"It seems that after leaving the small world of Dragon Valley, if you attach a soul ring, you can't choose the wurm species." Yu Tianlin thought thoughtfully, "Unless it is a pure dragon soul ring, all of them are high-level dragon power, or a soul ring without the slightest dragon bloodline, there is simply no trace of dragon power." As for the low-level dragon power of the impure sub-dragon species, it must not be touched. ”

In order to replenish the dragon power and improve the degree of dragonization, the soul master of the Blue Electric Overlord Sect had to absorb the soul ring of the subdragon species. But now it's different, Yu Tianlin found a dragon power overflow point, where all the overflow is pure high-grade dragon power, where he can absorb dragon power to improve the degree of dragon transformation, and he no longer needs to rely on absorbing soul rings to obtain dragon power.

Just like that, Yu Tianlin kept wandering in the plains, looking for the blue-purple thunder attribute dragon cloud to absorb.

After half a month, Yu Tianlin finally stopped searching for the blue-purple dragon cloud after discovering that Long Yun no longer brought out impurities from his body, and his physical strength had not improved much.

Now Yu Tianlin has changed a lot, in the state of dragonization, Yu Tianlin's dragon scales are full of texture compared to before, the edges and corners are more distinct, and they have a strong sharp aura. And as all the impurities on his body were expelled from his body, Yu Tianlin's whole person had a sense of relaxation and fluttering.

"Long Yun has not improved me much." Finally, after absorbing a dragon cloud, Yu Tianlin felt his body and said to himself, "I've been in the plain for half a month, so let's go directly into the forest, hunt the dragon soul and charge the dragon slaying knife, and then go all the way to the most central dragon cemetery to get those real dragon soul bones." ”

Thinking of this, Yu Tianlin didn't stop in the plains, and walked towards the forest with the dragon slaying knife on his shoulder.

After half a month, Yu Tianlin has gradually adapted to the aura of the Dragon Slaying Knife, and it is not open now, so Yu Tianlin has no problem carrying it.

Crossing the plain and entering the forest, Yu Tianlin had not taken a few steps before there was a sound of rustling in front of him, and soon, five dragon souls appeared in front of Yu Tianlin's eyes.

These five dragon souls are only half a meter tall, have no wings and no dragon horns, and the only advantage is that the fangs look a little sharp, and they are obviously just relatively low-level earth dragons.

"What kind of earth dragon is this?"

Seeing these five earth dragons, Yu Tianlin didn't recognize them for a while.

The dragon clan is very good at breeding offspring, so there are many kinds of earth dragons, even if Yu Tianlin's family history is not recognized.

Of course, the real dragon is different, there are only so many types of real dragons, and Yu Tianlin knows almost all of them.

At this time, while Yu Tianlin was looking, these five earth dragons surrounded him, and he was about to open his mouth and bite him.

Suffering from the attack of the dragon soul, Yu Tianlin's reaction was also very fast, and he instantly entered the state of dragon transformation of the whole body, and the powerful dragon power was released, and at the same time, he raised the dragon slashing knife to make a gesture to split.

If you want the Dragon Slaying Knife to absorb the power of the Dragon Soul, you must use the Dragon Slaying Knife to split it up personally, otherwise even if the Dragon Soul is killed, it can only be absorbed by the Soul Master, not by the Dragon Slaying Knife.

Seeing that the dragon slaying knife was about to slash at the nearest earth dragon dragon soul, the earth dragon dragon soul trembled, and the action of rushing over and biting suddenly stopped, not moving.

Why did it suddenly stop moving?

Yu Tianlin was stunned, although he didn't understand what was going on, but the movements in his hand did not stop, and he directly swung his knife and slashed down, and the earth dragon dragon soul let out a wail, and the energy body was suddenly shattered, turning into streamers and merging into the dragon slaying knife.

The moment the first closest Earth Dragon Dragon Soul was killed, the other four Earth Dragon Dragon Souls also underwent the same change, and all of them trembled and stopped attacking Yu Tianlin.

Well? What's going on? Why didn't these Earth Dragon Souls suddenly stop attacking me? In the records of the sect, there doesn't seem to be such a situation.

Seeing this scene, Yu Tianlin couldn't understand what the situation was.
