In the sea of knowledge of Long Chen, the strange dragon pattern on the mysterious dragon jade once again emitted a faint light, and a black light shrouded the drop of inheritance essence blood underneath!

The inheritance essence blood bound by Long Yu let out an unwilling roar, which shook Long Chen's sea of knowledge and rolled, but he still couldn't escape Long Yu's control.

The inheritance essence blood gradually moved towards the dragon jade, and in the next moment, they fused together, and the dragon jade completely turned blood red at this time.

At this time, Long Chen could see that the black dragon pattern on the dragon jade had turned red at this time. In this dragon pattern body, there were meridians one after another, and the appearance of these meridians was exactly the same as the dragon veins!

Before Long Chen could be shocked, he found that in the dragon veins of the dragon pattern, there was actually a trace of blood-colored power swimming in the dragon veins, and Long Chen carefully remembered the trajectory of the power volume, and his heart was already excited.

"This trajectory turned out to be a means of using true qi, similar to a combat technique!"

Whether it is dragon jade or inheritance essence blood, it is a very mysterious and powerful thing, and the running routes on dragon jade and the means of using true qi revealed are naturally not simple.

Long Chen hurriedly wrote down everything, and at this time, the blood color on Long Yu gradually receded, and the drop of inheritance essence blood was differentiated again, and was suppressed by Long Yu below, unable to move.

Long Chen didn't care to guess what this dragon jade was, he naturally used the magic decision that Long Yu had just appeared to run the blood-red true qi, and at that moment, Long Chen suddenly had a feeling of soul throbbing, because he suddenly understood the name and function of this law decision.

"Refining blood and transforming qi...... He was able to refine his essence blood and then turn it into his own true qi, this effect was several times more powerful than directly taking the spirit jade, or learning the beast martial artist to refine the beast pill!"

"This kind of law decision, although there is no grade, is definitely a supernatural power against the sky!"

With this law of refining blood and turning gas, and Long Chen had now pinched the heart of the blood lizard in the ground, he immediately used this law of refining blood and turning gas, and suddenly, a strange force acted on the blood lizard's body.

Long Chen could feel that the other party seemed to be in great pain, so Long Chen crushed its heart and let it die directly, lest it be directly tortured to death by this pain.

After the blood lizard died, under Long Chen's blood refining qi, the blood on its body rushed towards Long Chen frantically, and there was not even a trace left!

At this time, every piece of scale armor on Long Chen's body seemed to turn into a huge mouth, and they swallowed these blood qi into it.

Under the powerful effect of refining blood and transforming qi, with a bang, those blood bursts one after another, and many impurities are expelled from Long Chen's body, and the rest of the blood is completely turned into blood-red true qi, integrated into Long Chen's dantian true qi!

The amount of power contained in the bloodline of this underground blood lizard is comparable to a hundred spirit jades, and after tasting the sweetness, Long Chen, who still felt hungry at this time, suddenly turned his eyes to the other blood lizards!

With the support of the powerful method of refining blood and transforming qi, Long Chen carried out a one-sided slaughter of the underground blood lizards, although now Long Chen is still the fifth level of the dragon vein realm, but compared to these blood lizards, he is much stronger, especially his body of bone spurs, piercing into the body of the blood lizard, as if it is as easy as stabbing into tofu!

Under the blood qi of the blood lizard, Long Chen's hunger slowly disappeared, and the quantity of his true qi had gradually caught up with the state before he touched the dragon seal, but in terms of quality, it had increased tenfold!

Seeing Long Chen so crazy, Ling Xi felt a little unbearable, but demon beasts and human races are two different races, usually the human race hunts demon beasts, and powerful demon beasts also kill human races, this has become a law.

And the wisdom of the demon beast is underneath, so she can't say anything, Long Chen killed the other party before using the blood refining qi, which shows that his heart is not completely affected by the bloody killing aura in the inheritance essence blood.

Long Chen was about to stop, when suddenly Lingxi's anxious voice came.

"Long Chen, there is a huge demon beast under this ground! The strength is the seventh rank of the Yellow Order, do you want to escape?"

The demon beast of the seventh rank of the Yellow Order, in exchange for the small life that could casually take Long Chen's life in the past!

She couldn't figure out what Long Chen's strength was after he became this body, so she talked to him with an inquiring attitude. At this time, Long Chen was stunned.

"Yellow Rank Seventh Grade, just as I can verify the strength of this body......"

The demon beasts of the seventh rank of the Yellow Order are basically more powerful than the seventh-level martial artists of the Dragon Vein Realm!

When this thought just appeared in Long Chen's heart, the entire underground suddenly shook, and at this time, a roar similar to a dragon's groan came from the ground, and the quagmire suddenly exploded, and a huge scarlet monster appeared in front of Long Chen's eyes!

This is an enlarged version of an underground blood lizard, more than twenty meters long, covered in blood-red scale armor, and two scarlet eyes larger than a basin, looking extremely hideous!

"It's the Underground Blood Lizard King!No wonder, there are so many Blood Lizards here, it must be because of the existence of a king!"

In the face of the powerful demonic power of this Blood Lizard King, Long Chen did not take half a step back.

Long Chen killed so many blood lizards, seeing such a scene, the blood lizard king was already extremely angry, although it could vaguely feel that Long Chen was very mysterious and weird, but this could not make it forget the anger in his heart!

"This ugly monster looks like he's trying to kill me, but you're just food for me!"

A cold light flashed in Long Chen's eyes, his current speed was more than ten times faster than before, as long as his body moved, it seemed to turn into a blood shadow in this cave, but Long Chen could also see that the speed of this blood lizard king's tongue was also very fast!

Long Chen only moved one step, and that large piece of blood-red tongue, carrying a monstrous amount of power, instantly appeared above his head, Long Chen suddenly threw a punch, and collided with him once, only to find that the strength on the blood lizard king's tongue was almost the same as him, and this attack directly shook Long Chen's legs into the ground!

"Anyway, I'm already full today, and I don't have time to waste it with you! I learned the Canglong Seal until now, and I haven't used it yet, so I'll let you try it today!"

Long Chen lowered his head, his eyes that had become scarlet at this time burst out with a strong cold light, at this time, although his palm had turned into a claw, it did not affect the seal at all, the blood-red air flow began to roll rapidly between his palms, a powerful coercion, towards the blood lizard king, and the dragon seal also quickly formed in Long Chen's palm!

"Canglong Seal!"

When the blood-red true qi had turned into a blood-colored little dragon coiled around Long Chen's palm, the Blood Lizard King suddenly felt the threat of death, and it hurriedly retreated!

But at this moment, the originally gloomy cave suddenly shone with a blood-red light, and a blood-red dragon image flashed away, hitting the head of the Blood Lizard King, and when that low dragon roar sounded, the Blood Lizard King had burst out of his brain and was completely dead!

Yellow Rank Seven Pins, Die!

This is the most powerful opponent that Long Chen has killed so far, and Long Chen estimates that even if it is the White Century, he will not be able to ask for any benefit against this Blood Lizard King!

Killing this blood lizard king, feeling the other party's abundant blood breath, of course Long Chen couldn't let it go, he jumped on the back of the blood lizard king, and carried the method of refining blood and transforming qi, and suddenly a huge amount of blood surged from the huge blood lizard king's body.

There were tons of this blood, but under the refining of Long Chen, the king of big stomachs, about nine-tenths of the waste was refined, and only then did he turn all the remaining essence into blood-red true qi and integrate it into the dantian!

The essence blood of the Yellow Rank Seventh-Rank Demon Beast, this is not a joke, Long Chen instantly felt that his true qi was soaring, and he soon reached a critical point.

He was hungry and uncomfortable before, but now he is uncomfortable, and Long Chen finally waited for him to hit the sixth dragon vein!

Just sitting cross-legged on the Blood Lizard King's body, the next moment, all the true qi turned into a blood-red dragon, roaring towards the sixth dragon vein!

What shocked Long Chen was that this blood-red true qi dragon seemed to have spiritual wisdom, bloody and ferocious, the accumulated dragon veins were fragile in front of the eyes of this blood-red long dragon, and Long Chen's true qi had skyrocketed to the extreme point of the fifth level of the dragon vein realm, so when it came to the sixth level, it was unprecedentedly simple.

In less than a quarter of an hour, the sixth layer of the dragon vein was unexpectedly penetrated, and a huge amount of heaven and earth aura poured into Long Chen's body, and his current strength was completely at the sixth level of the dragon vein realm!

Before the Demon Hunting Competition, he finally reached the sixth level, and feeling the extremely strong energy in his body, Long Chen finally smiled.

There was such a big commotion, Long Chen didn't dare to stay here, he hurriedly walked out of the underground cave and headed towards the previous cave, but what he was depressed about now was that he was like this, what should he do?

Just as he was struggling with this matter, he suddenly felt a strange itch, and at this moment, the scales and bone spurs on his body slowly dissipated and merged back into his body, and he was now back to his original appearance.

However, when he eliminated this transformation, he could also feel that the inheritance essence blood that had spread throughout his entire body was also slowly receding, and finally condensed into a small red dot in the center of his eyebrows.

The original blood-red true qi that had increased tenfold in nature, the original blood-red color gradually faded, but the remaining true qi still carried a trace of blood-red, and its nature was about four times higher than that of ordinary true qi!

Long Chen's strength, which had skyrocketed because of his transformation, had only slowly retreated now.

However, at this time, he was still much stronger than the other dragon vein realm sixth level, coupled with his cultivation on the dragon seal, Long Chen believed that even if it was the seventh level of the dragon vein realm, he would still be able to deal with it!

Long Chen felt a little sorry for the retreat of the strange transformation before, because that was his strongest state, but that appearance really couldn't walk in this world, so there was no way.

"I don't know if I can still become that state, this mysterious dragon jade is so magical, I think it should be possible. ”

Even if it doesn't become that state, it should be enough to participate in the Demon Hunting Competition.

And after Long Chen lifted the strange transformation, everything returned to calm, and Ling Xi couldn't wait to ask him: "Long Chen, what kind of dragon is the inheritance essence blood you obtained?"
