There is a singular resonance between the mother and daughter of the soundworm. Speaking to the valve of the child worm, there will be a clear echo after the valve of the mother worm.

With this principle, long-distance communication can be realized. In some special areas where the sound transmission array cannot be transmitted, the sound worm can play a great role.

And on the opposite side of this foothill, in another mountain col, a group of black-robed underworld powerhouses also gathered in front of a bronze giant gate.

"Elder Stygian, your faces are a little pale, and you're ...... There are several World Venerable Elders missing!" Elder Immortal led a group of Xuan Emperors of the Underworld Clan to greet him, and said in surprise.

"Alas...... It's all thanks to King Jin Tai and Xu Yang!" The Immortal Stone Shizun waved his hand, gritted his teeth and said, "Don't talk about this, King Jin Tai has his own clan master to deal with, as for this Xu Yang, the old man will have to settle accounts with him sooner or later! Elder Immortal, this is the entrance to the underground palace you are talking about? Are there any people from the Royal Beast Clan passing here?"

The Immortal Sect said: "Where do the group of Xuanhuang juniors of the Imperial Beast Clan dare to follow the Underworld Brigade led by me? I didn't bother to spend time looking for those Xuanhuang-level juniors, but sent a large team of people to search for information, and sure enough, I found the entrance to this underground palace. ”

"Elder Immortal, have you opened the palace gate and entered to take a look?" asked the World-Honored One.

"Well, there is a mysterious power seal on the gate of this palace, but with my strength, it is enough to break it. After entering, I took a general look, and in this underground palace, the palace corridors are really a little intricate, and there are faint traces of formations! If you enter rashly, I am afraid that you will get lost in it. That's why I didn't go deeper. ”

The Immortal Stone World Venerable said categorically: "Okay, since that's the case, let's go inside together and find out!"

After these Hades World-Honored Ones led their Xuanhuang-level clansmen into the underground palace, Xu Yang's figure quietly appeared. Emerge from behind a pile of rubble.

"According to Jin Gu's soul transmission, he has found an entrance to the underground palace. And here, the Immortal Sect World Venerable also found a ...... In this way, there is not only one entrance to this underground palace!"

"Little Xuanzi, you're right!" On the bronze plate, a lewd old man's face appeared, his mouth opened and closed, and said, "In the underground palace." I don't know what kind of treasure there is, it will definitely cause bloody strife. In order to reduce their fighting, little Xuanzi, you should go and get the treasure. ”

Xu Yang smiled slightly, this obscene bronze plate can always snatch treasures, and it is so high-sounding and awe-inspiring.

"Okay, then let's go!" Xu Yang took a step. Suddenly, not far behind me, a voice full of hatred sounded:

"Xu Yang. Where to go?!"

The wind was howling, and a majestic blood power blasted through the air, turning into a hideous dragon! Xu Yang's figure flickered, and he disappeared in place with a bang, leaving only a puppet incarnation!

There was a boom. The puppet was bombarded to pieces.

Xu Yang's face was slightly cold, he had already seen the person coming, and said coldly: "King Jin Tai? ”

The person who came was King Jin Tai with a gloomy face. His face was still a little pale, but it was much better than when he was in the five-colored stone hall. Apparently. He has been following Xu Yang without making any trouble, just to wait for Xuan Li and his injuries to recover, and then stand up and clean up Xu Yang with absolute certainty.

King Jin Tai sneered: "Xu Yang, you and I are incompatible, of course I will not let you go." Come on, there's no bubble space right now to disrupt my hunt for you. I see how you can escape this time!"

As he spoke, King Jin Tai stepped out, his hands quickly sealed, and an illusory tiger quickly took shape above his head.

"Tiger Fist Print!"

King Jin Tai blasted out with a fierce tiger fist print, and the bloody wind was blowing in the flat ground, and a burst of palpitating tiger power shocked him. If you put it in an ordinary half-step world, you must have been shocked by the power of the tiger contained in this fist seal, and your combat power plummeted.

However, Xu Yang is also the spiritual cultivation of the Four Tribulations World Venerable, and he is not weaker than King Jin Tai. Almost instantly, he broke free from the power of this fierce tiger, and used the superimposed secret technique, a fist of the earth, wrapped in the momentum of the boundless overlord, and attacked the tiger fist mark of King Jin Tai.

"Tom!"

The thunder burst out, and at the place where the two fists collided, a brilliant golden light collided with the brilliance of the blood power, and the wind was shining.

Xu Yang's body shook and he took three steps back. And King Jin Tai's body also swayed, and he took a small step backwards! It was only a small step, but it was enough to show that Xu Yang's strength was beyond King Jin Tai's imagination.

You must know that in the five-color stone hall, when the two sides were facing each other, Xu Yang was still far inferior to King Jin Tai, and he was shocked by a punch and fell into decline. Fortunately, there was a bubble space at that time, otherwise it would be difficult for Xu Yang to withstand the next series of offensives.

However, this time, in the duel between Xu Yang and King Jin Tai, although he still fell into the upper hand, the gap between the two sides had narrowed a lot! King Jin Tai faintly felt that Xu Yang's fist power was several times stronger than the last time, which was also the reason why he had to take a small step back and unload the power of the shock.

"Good boy, how long has it been since the last confrontation? Moreover, the last time I fought against each other, my Xuan Li was empty, and I still had injuries on my body, so I couldn't help but leave some spare strength when I fought against the bombardment; this time I had already recovered my Xuan Li and my physical body, and I could call it all my strength! This kid's progress speed is simply outrageously fast, and if this continues, when he is promoted to the Bone Change Realm, won't it be enough to compete with me?"

As soon as he thought of this section, King Jin Tai's eyes were filled with anger, and he clearly realized that if he didn't kill Xu Yang now, after a while, it would be Xu Yang's turn to kill him!

"Good boy, eat me with a move, dragon snake strike!"

King Jin Tai gritted his teeth, and his left and right arms vibrated up and down like waves, looking like a long snake and a dragon, swimming in a meandering way! Blood mystic power was infused, and in an instant, the phantom of a snake and a dragon emerged from above his arms, volleying into the air, and flying towards Xu Yang!

"Purple Gold Emperor Armor, Nine Heavenly Palace!" Xu Yang instantly opened his defense, and under the shroud of a layer of purple gold light, the Nine Heavenly Palaces unfolded one after another, as solid as a rock.

The long snake's body was agile, and it instantly entangled Xu Yang layer by layer, and then the dragon slammed into it!

A dragon roar sounded, a rumbling thunder roared, and the splashed smoke and dust completely submerged Xu Yang's body! The surging and surging energy of the wind shot out in all directions. (To be continued......)
