Yuan Chen returned to the post station, sat up cross-legged in the room, and placed the black dragon jade seal in his hand in front of the table in front of him by the way.

"Although this black dragon jade seal is extremely hard, I have used various means to investigate its interior along the way, and there seems to be nothing subtle. ”

Rarely giving birth to a trace of incomprehension, Yuan Chen tried to throw the black dragon jade seal that was quite weighty in his palm, giving birth to a substantial puzzlement.

Although he can't say that he has a lot of experience, he can at least see some clues about the treasure of heaven and earth, but this black dragon jade seal just can't let himself touch the head and tail, because under his own various investigations and perceptions, this jade seal is just like an extremely ordinary jade seal, without the slightest psychic omen.

"There's a lot of stuff you don't know, bring it. ”

Ye Ling had discovered a hint of this black dragon jade seal from the very beginning, although he asked Yuan Chen to hand over this black dragon jade seal by himself, but in fact, he had already grasped the jade seal in Yuan Chen's hand in his palm, and then his delicate palm stretched into the inside of this black dragon jade seal as if there was no obstacle.

Since this thing is a symbol of the Sound Demon Palace, then the hiding of the mystery is naturally also amazing, but when it comes to the night spirit, no matter how much it is hidden, it will definitely not be able to hide, I am afraid that the ink tapir and others did not expect even if they wanted to break their heads, and the most precious thing was in this jade seal.

"Hmph, such a small mechanism still wants to hide from my eyes?" After a while, I saw that one of the ink-colored beads that specialized in concealing spiritual power fluctuations was grabbed into the palm of the night spirit, and it was forcibly sealed in an instant of struggle.

Obviously, it is a kind of spiritual weapon that specializes in deceiving all kinds of reconnaissance and detection, after all, ordinary people must cut the jade seal if they want to find this thing, but who will have such a means as a night spirit similar to the wall-piercing technique?

"This is the real black dragon jade seal, this should be the medium to contact what is sealed, release the blood from the palm of your hand, and let the jade seal be printed in your palm You should know what it is. ”

Ye Luo said as if he was trying medicine to eat an immortal, but he didn't think that if this black dragon jade seal was something highly poisonous, Yuan Chen would not plant it.

"I still haven't figured out the details of this thing for the time being, so I think it's better not to risk yourself. ”

Yuan Chenzheng said, but who expected that Ye Ling might let him voluntarily donate blood, and grabbed his palm as soon as he grabbed it, and the black dragon jade seal in his hand pressed heavily on the young man's palm, causing a burst of violent pain.

"Do you want to be so rude?" Yuan Chen felt a dragon-shaped seal on his palm that was quickly imprinted by his own blood donation, only to see that the original blood-red mark quickly turned into a mysterious dark color, like a faint tattoo submerged into the young man's palm, causing an extremely hideous dragon roar to rush directly into the young man's body.

If it weren't for Yuan Chen's incomparably tough meridians, just such a domineering dragon chant would be enough to break his meridians!

"Sure enough, it worked, this black dragon seal really hides a mastery of the Sound Demon Palace!" "Night Spirit Zheng Ran's pretty face, already anticipating some speculation, tried to make Yuan Chen open his mouth.

"Open your mouth and feel the dragon qi that is injected into the veins in your body, this is the essence of the Sound Demon Palace's Demon Sound Dragon Roar, you are equivalent to directly receiving the instillation of the strongest martial arts in the Sound Demon Palace. "At this moment, even the night spirit is shocked by the mystery contained in this black seal.

Unexpectedly, the ancestor of the Demon Sound Palace would directly seal the mystery in a jade seal.

Yuan Chen tried to feel the surging dragon qi in his body, and when he looked inside, he saw that in the churning inner sea of his body, an extremely obscure dark ink dragon soul soared up, between one of his thoughts.

"Boom!"

A surging ring sound wave slammed into the world, causing a burst of panic, and with the loud sound of many houses being instantly shattered, impacting thousands of miles, so that countless people's hearts were shocked instantly.

Only feeling that the room he was in seemed to be about to collapse, Yuan Chen couldn't help but look at the black dragon jade seal in his palm, and naturally knew that the powerful power brought by his roar was naturally caused by the increase of the ink dragon soul in his body.

After all, the ultimate of the sonic technique is to integrate into the ancient true dragon and true phoenix beast soul to become powerful, and this black dragon jade seal seals the remnant soul of a black dragon, which also officially reaches the power of this magic sound dragon roar to perfection.

The Sound Demon Palace's eighth-order sonic martial arts magic sound dragon roar is the secret technique of the entire Sound Demon Palace, but now it has been obtained by Yuan Chen by such a coincidence, there is no doubt that this will be a huge help, after all, if the two sides fight in a stalemate in the martial arts, such a heart-destroying sonic attack will be enough to reverse the entire battle situation!

But at this time.

"Wow!" The original black dragon jade seal in his palm melted into his palm like a shadow.

Both Ye Ling and Yuan Chen himself were slightly surprised, could it be that this black dragon jade seal was a strange spiritual weapon with some parasitic effect?

But Yuan Chen still reluctantly put his heart down after entering the Inland Sea in his body.

I saw that at this moment, in the sky above his own inland sea, a black dragon jade seal with a mysterious color was quietly hanging on it, although Yuan Chen tried to force it out of his body several times, but to no avail.

However, this black dragon jade seal entered his own inner sea and warmed up without taking the next step, Yuan Chen still secretly put his heart at ease, fortunately, although this black dragon jade seal can't help it, but it seems that this thing is not too much of a threat to itself in a short period of time, so it doesn't move Yuan Chen and is not ready to care, this feeling that he has a hair on his head and can't pull it out is a little aggrieved.

"It doesn't seem like this thing will do you any harm anytime soon. The night spirit figure also flashed in the sky above the young man's inland sea, and after thinking about it for a long time, he couldn't do anything about this black seal, so he could only hastily let this black dragon jade seal stay here.

"The more important thing at the moment is to enter the Sound Demon Secret Vault, and it seems that this Black Dragon Jade Seal can only be tolerated temporarily. Although he didn't know what bad results would happen if this thing stayed in his body for a long time, Yuan Chen was still not prepared to continue to waste too much time, and in the blink of an eye, he began to prepare for the trip to the Sound Demon Secret Vault that would come soon.

At the same time, the faces of the Yeyan Bat Purple Bat Seal became more and more hideous, and the faint shame of many people kneeling on one knee behind him.

"The power of the sound wave that came out of the entire Xilan Post Station just now should be the long-lost magic sound dragon roar of my Sound Demon Palace, right?"

This night, Yan Bat's narrow-minded heart is even more hideous at this moment.

It took him decades to complete the cultivation of the second secret technique of the Sound Demon Palace, Yin Bat Ghost Howling, but who would have thought that now there seems to be a more perverted opponent who will learn the lost Demon Sound Dragon Roar, how can he bear this?
