Immediately, Sun Chengcheng sat down cross-legged next to the Panlong stone wall.

But all the names of the exercises have a deep meaning.

"The Ancient Dragon Secret Formula" is no exception, and there is one of the most core secrets in it, which is the "Dragon Sucking Secret", which is specially designed to absorb dragon veins.

When you encounter the right dragon vein, you can activate the "Dragon Sucking Secret", devour the dragon vein, and transform your own true element into the true element of the dragon vein.

Only by condensing the true element of the dragon vein in the body can it be regarded as a preliminary cultivation of the "Ancient Dragon Divine Technique", which can show the various magical powers of this supreme exercise.

Sun Cheng's mind sank into the dantian, starting with the dantian, the true yuan in his body began to operate, and according to the "secret of dragon absorption" in the "Ancient Dragon Divine Formula", he rushed in the meridians.

At the same time, on the stone wall, the coiled True Flame Earth Dragon also seemed to sense something, and became uneasy, and began to emerge, slowly squirming in the stone wall.

Sun Zhengyang, who was on the side, was slightly surprised, and couldn't help but secretly think: "Cheng'er, what kind of exercise is this cultivation? ”

After a while, in Sun Cheng's dantian, a true yuan vortex was formed, and countless true yuan were sucked into it, compressed, and condensed.

For a while, the pores on Sun Cheng's body were all opened, and countless heaven and earth aura were absorbed by him, put into the meridians, turned into true yuan, and then swallowed by his dantian.

The aura in the entire secret room dungeon was rapidly absorbed and consumed, and in the end, because it could not be replenished, it formed a vortex of spiritual energy that seemed to be materialized above his head, spinning rapidly.

Even, a gust of wind was stirred up by the spiritual energy whirlpool, blowing the entire stone wall of the secret room dungeon.

When Sun Zhengyang saw this scene, he couldn't help but be shocked. When he was at the peak of the Yuan Martial Realm Nine Heavy Cultivation before, he wasn't so crazy when he cultivated!

He was far away, and he actually felt that from the top of this spiritual energy vortex above Sun Cheng's head, as if there was an infinite suction, it was like absorbing his essence and spirit.

This, this is simply a black hole of aura!

"Roar!"

The dragon veins on the side were originally hidden in the stone wall, but at this moment, they also felt a huge threat, and they screamed eagerly, and they actually manifested their true bodies from the stone wall frantically, circling above the secret room dungeon.

The horns are like deer, and the head is like a camel...... It was three claws long, and its whole body was red, shrouded in a red firelight.

Sure enough, it was a living True Flame Earth Dragon Vein.

Ancient legends: The earth dragon has three claws, the sky dragon has four claws, and the real dragon has five claws.

Faced with the threat of life and death, this True Flame Earth Dragon immediately went berserk, struggling desperately to escape.

However, just as the True Flame Earth Dragon was about to touch the ceiling of the secret dungeon, a black light curtain suddenly appeared, suppressing it forcefully, and no matter how hard it tried, it couldn't escape.

This shady curtain was manifested by the trapped dragon bureau, and it was originally aimed at this true flame dragon.

With the rapid rotation of the aura black hole above Sun Cheng's head, although it failed to expand, the suction power in it became more and more powerful.

The True Flame Earth Dragon had no way to escape, but was finally captured by this powerful suction, and could no longer break free, and threw itself towards the aura black hole.

Then the powerful aura squeezed, little by little, and finally gathered into a very small red dot, merged into the aura black hole, and disappeared again.

In an instant, Sun Cheng only felt a huge shock in his body, and a scorching breath rushed into his body from the top of his head, and rushed wildly in the meridians.

The sharp pain from the burning began to spread through his body.

If it weren't for Sun Cheng's rebirth, he had experienced too many things in his past and present lives, and he would have already cultivated steel-like willpower. I'm afraid I'll be crushed by this near-extreme pain on the spot. Then Zhenyuan rioted, exploded and died.

Sun Chengqiang endured the pain and controlled the True Yuan in his body to chase this True Flame Earth Dragon. Almost every time the True Yuan runs in the body, it can absorb a trace of the power of the True Flame Earth Dragon.

Gradually, the power of the True Flame Earth Dragon became weaker and weaker, while Sun Cheng's True Yuan became stronger and stronger.

Finally, at a certain moment, the true spirit of the True Flame Earth Dragon was completely wiped out and turned into a True Flame Dragon Ball.

As soon as the True Flame Dragon Ball was generated, it followed the meridians and fell directly into the dantian, and then it was included in the True Yuan Vortex, and then it was suppressed and sealed.

And because of the existence of the True Flame Dragon Ball, the True Yuan Vortex was also solidified, coexisted with the Dragon Ball, and existed in Sun Cheng's dantian for a long time.

It wasn't until this moment that the True Flame Earth Dragon was completely subdued by Sun Cheng, and his tense nerves finally relaxed, and he secretly breathed a sigh of relief in his heart.

As for the True Flame Dragon Ball, it will be consumed by the True Yuan Vortex little by little for a long time to come, until it is completely absorbed by Sun Cheng.

However, at this time, it is not yet time to really rest.

How huge is the power of a dragon vein? Even if he has been trapped for so many years and consumed most of his strength, the amount of the remaining small part is far from being comparable to Sun Cheng, a martial artist who has cultivated in the Yuan Martial Realm, even if his actual combat power is equivalent to the Yuan Martial Realm Triple.

If there is no trapped dragon situation, trap the dragon vein.

If it weren't for the secret of sucking the dragon, it would be a special restraint for the dragon veins.

If Sun Cheng wanted to absorb this True Flame Earth Dragon, it was completely impossible.

In the process of sealing the dragon vein just now, when the True Flame Earth Dragon was fleeing and struggling, it escaped countless True Flame spiritual power, which was entangled with the original True Yuan in his body.

A feeling of swelling filled Sun Cheng's meridians......

This power was definitely not something that he could control with the cultivation of the Yuan Martial Realm.

"In that case, let's break through. ”

Immediately, Sun Cheng began to practice, and the true yuan in his body began to run rapidly according to the first chapter of the "Ancient Dragon Divine Formula".

The hidden dragon chapter is broad and profound, and he is just getting started.

With each rotation of the complex and huge True Yuan in the meridians, its total amount will be consumed by one point, and the degree of condensation will increase by one point.

I don't know how long it has been, Sun Cheng only felt a loud bang in his body.

All the true elements retreated into the dantian like a tide, and when they came out again, they were more than twice as condensed as before, although the quantity was still the amount before the beginning, but the quality was completely different.

The Yuanwu realm is double, broken.

At this moment, Sun Cheng was extremely arrogant in his heart, and he could feel that compared to himself before the breakthrough, he could now fight three at a time.

Looking at Sun Zhengyang from afar, he also saw Sun Cheng's changes at this time, and he was already stunned. At the beginning, he could see that although Sun Cheng's combat power was extraordinary, he was not worse than any martial artist in the Yuan Martial Realm, but his actual cultivation was only one in the Yuan Martial Realm, and he was still in a state where he had not broken through for a long time.

Now it's a breakthrough again.

How long has it been? three months, two months, or a month?

If he knew that only five or six days had actually passed, he would have been shocked that his big teeth would have fallen off, and no matter how genius he was, he would not be such a genius.
