Looking at the ancient underground city that was close at hand, several people were in a hurry.

They don't have blood yang crystals in their hands, it's not that blood yang crystals are so rare, it's just that blood yang crystals are very ordinary treasures, they can be purchased in some shops in Dongyunyang Town, and they actually need that kind of thing to enter the underground ancient city, which is very surprising.

"Looking at the depression on this stone stele, it is obvious that the blood yang crystal is placed, but it is difficult to say, whether it is a whole piece or a small piece can be stuffed into it. Shi Feng said.

"If some blood yang crystals are stuffed in, I'm afraid it will be difficult to open. Xiao Qi said.

Shi Feng thought for a moment and said, "Brother Xiao means that if it is a fine blood yang crystal, this underground ancient city should have been opened a long time ago." ”

Xiao Qi said: "Yes, even if it is difficult for anyone to find here, it does not mean that no one has come here for ten thousand years, so it is best to have a complete piece of blood yang crystal." ”

"Complete, then it's hard to find, at least in the shops in Dongyunyang Town, there are absolutely none. Shi Feng said.

"An ordinary small fragment of Blood Yang Crystal is just an ordinary treasure, such a big one, it is definitely at the level of a rare treasure, but it is very rare. Xiao Qi groaned, "However, it's not nothing, just west of this mountain, about 3,000 meters away, there is a valley, called Blood Yang Valley, it is said that there is the blood yang crystal vein, and now the blood yang crystals scattered all over the place, ten *** are produced there, it should be possible to have such a large piece of blood yang crystal, but it is ......"

"Brother Xiao said. Shi Feng said.

Taking a deep breath, Xiao Qi said: "There is a demonic beast in the Blood Yang Valley, called the Wind Roar Beast, which is a five-rank martial arts venerable level, and is good at flying, extremely fast, has a special natural ability to roar, and can kill people with sound waves. ”

Shi Feng said: "Since there is, then you have to try it." ”

In the underground ancient city, it is very likely that it is the place where the Barbarian True Monarch is buried, not only there are treasures, but more importantly, it is very likely that there is the Heavenly Divine Spear of the Barbarian True Monarch, which is the temptation that Shi Feng cannot refuse.

With the Heavenly Divine Spear in hand, it can definitely increase Shi Feng's combat power more than twice out of thin air.

If he used the Divine Spear to pierce the moon, he was only fifty or sixty percent sure of facing the Fifth Rank Martial Venerable, and if he had the Heavenly Divine Spear, with his second-grade Martial Zun's strength, he would have the confidence to easily kill the Fifth Rank Martial Venerable.

Weapons often play a decisive role.

Not to mention that there may be other treasures.

This place was selected by King Shura as one of the inheritances near Dongyunyang Town, and the underground ancient city obviously existed before the holy war, it is difficult to guarantee that the place where King Luo chose this place as one of the inheritances has nothing to do with the underground ancient city.

So no matter what, he was going to enter the ancient city.

"You stay, mainly Ye Yu's best Earth Yuan Pearl, cultivate here, at most three days, and I will come back. Shi Feng admonished.

And he departed.

Walking out of the cave, he made out the direction, diagonally opposite was a high mountain, and one of the crooked-necked trees poked out, which was more than two hundred meters away from him.

Sou!

Two huge vortices flashed under Shi Feng's feet, and he flew up directly, spanning a distance of more than 200 meters, landing on the crooked neck tree, and then galloped along the cliff to reach the top of the mountain.

Running with your feet on the ground is faster, and it consumes less spirit yuan.

He made his way to the top of the mountain.

Standing here and looking west for a while, he headed straight to the west.

The Blood Yang Valley was located in the west, not too far, more than three thousand meters only, Shi Feng ran up, and soon, he reached the vicinity of the Blood Yang Valley.

Speaking of which, Xueyang Valley is particularly obvious, that is, the ground here is red, it looks like splashing blood, it is just some gravel, and the flowers and plants are pale red, which is very different from normal places.

Shi Feng carried the spear and cautiously entered it.

"Roar!"

Before he could even step into it, an earth-shattering beast roar was heard.

The sound seemed to have some special power, burrowing into the ears and straight into the head, like an electric drill, indescribable pain.

Before Shi Feng entered, there was a trace of such an unbearable feeling.

It was very uncomfortable.

"It's a natural ability of the Wind Howler. Shi Feng immediately made a judgment, "The Wind Roar Beast has natural abilities, and there are two kinds, one is speed, the other is sound waves, the combination of the two makes it in the realm of the Five Rank Martial Arts, that is almost invincible, it is estimated that the Seven or Eight Rank Martial Masters are unwilling to fight with it, it is the roaring sound wave, too perverted, too fierce attack, and there is no good way to resist, which is also the main reason why the Wind Howler Beast can never be exterminated." ”

Shi Feng also knew that it was impossible for such a demonic beast to launch an attack unless it was necessary.

There must be something that angers it, and it will be angry.

He cautiously entered the Blood Sun Valley.

"It's them!"

Standing in a corner, Shi Feng saw at a glance the person standing on the outermost periphery, it was Zuo Yuanhao, the son of Zuo Husheng, the leader of the Silver Tiger Adventure Group.

In other words, it was the people of the Silver Tiger Adventure Group who were fighting against the Wind Howler.

Looking closely at the past, the battle was extremely fierce.

Those martial venerables joined forces to besiege, even so, they were still at a disadvantage, and the wind roaring beast that was besieged in the middle, from the outside, looked like a divine horse, with a jet-black body, flowing hair, the difference is that there are sharp horns on the top of the head, the tail is a crocodile tail, sweeping around, full of strength, strong limbs, nearly three meters high, from time to time it roars, with bursts, although it is not a deliberate sonic attack, it is still as loud as thunder.

"Good Divine Beast. Shi Feng exclaimed.

From the appearance alone, it is not inferior to the lightning silver wolf.

Seeing it arrogantly looking at the adventurers of the Silver Tiger Adventure Group, full of contempt, it shook its head twice, and let out a low roar like thunder, and the crocodile tail that seemed to be very incompatible with the body was swept lightly, and the wind roaring beast immediately disappeared in place, leaving an afterimage that slowly dissipated, and it reappeared, but it had already arrived in front of a third-grade martial artist.

"Click!"

The front hooves of the Wind Howler Beast stepped down fiercely, and the three-rank Martial Venerable immediately blocked it with a long sword, but as a result, the Wind Roaring Beast's hooves stepped on it, and the sword was shattered in one fell swoop.

The terrifying power was also transmitted, and the blood spurting of the Sanpin Martial Venerable Zun flew out upside down.

"Beasts are looking for death!"

"Die, slew the beasts!"

The other adventurers were furious, swinging their swords and slaying them.

Letting these people rush over, the Wind Roaring Beast didn't make any moves, just looked at them haughtily, his eyes full of contempt.

"I guess I'm going to attack with sound waves, so I'll try to see if I can resist. Shi Feng muttered in his heart.

Refining includes all parts of the body, including the ears.

Whether it was useful or not, even he didn't know, at least when he was at a distance, his ears didn't repel those sound waves to a certain extent.

"Roar!"

The Wind Howler suddenly raised its head and let out a roar.

The beast's roar was like a thunderbolt exploding, and the void seemed to be cracked one after another, with its body as the center, radiating out to all sides, quite shocking.

At that moment, Shi Feng's heart was moved.

If you have the opportunity to find a monster whose natural ability is sonic attack among the top monsters, you will also get this ability if you use it to refine the beast.

The roar is heavenly.

Visible sound waves appear in a circular circle and spread out in all directions.

"Dangdangdang......"

The visible sound ** pattern continues to impact the weapons in the hands of those adventurers, making a crisp sound, each impact is hit in a certain position, so that those weapons begin to appear cracks, of course, where the position is blocked by the weapon, those ripples will be broken, obviously the sound wave seems to be invisible, but in fact it can be blocked with weapons.

Seeing this scene, Shi Feng also breathed a sigh of relief.

If it can't be stopped, then the Wind Roar Beast will really be terrifying to the point of being incomparable, and it will definitely not be listed as a fifth-grade martial artist's strength.

Some of the shattered sound lines rippled towards Shi Feng's side.

The sound waves vibrate, causing the air to fluctuate as well.

Shi Feng was able to keenly grasp the pattern of the sound wave oscillation, and his spear pierced the moon slightly.

"Bang Bang Bang"

The series of attacks shattered his sonic waves and was shattered by the sharpshooter.

Naturally, he couldn't touch Shi Feng.

Shi Feng felt the vibration of that frequency, which was very distinctive, and it seemed that by roaring, a certain frequency of oscillation was formed, resulting in a similar attack.

It's a wonderful sonic attack.

This kind of characteristic thing is still very attractive to Shi Feng, if it is a simple spiritual skill, no matter how aggressive it is, he will have little interest.

"Bang!"

The shattered sound wave, it was easy for Shi Feng to resist, but Zuo Yuanhao, who was standing on the periphery, was different, after he was tumbled in the air and fell to the ground, he took more than ten steps backwards in a row, and only then did he stabilize his body, and blood flowed from the corners of his mouth.

As for the others, they were strong and resisted, but a few weapons finally broke under several sonic attacks, and they were injured and retreated, which made the encirclement and suppression significantly weakened.

Shi Feng secretly calculated, if he fought with it, he was afraid that it would be difficult to resist, this wind roaring beast would definitely be able to make the six-rank martial arts jealous existence, it was obvious that the people of the silver tiger were also afraid that it would be difficult to resist, if it was like this, if it was like this, if it was like this, it would be the size of a human head, and there was absolutely no hope.

The Wind Howler Beast likes to rest on the Blood Yang Crystal the most.

The chunk must be in its cave.

Therefore, if he wants to obtain the Blood Yang Crystal, he can only have a chance when he uses these Silver Tiger Adventurers to contain the Wind Roaring Beast, and he takes the opportunity to enter the Wind Roaring Beast's cave.

Thinking of this, he quietly left this place.

The cave of the Wind Howler is behind it, and it has never left it from beginning to end, so it is not so easy to enter it, and it needs to look for opportunities.

Shi Feng then circled around a large circle and came to the location of the Wind Roaring Beast Cave Mansion, where he stood about a hundred meters above the vertical height of the cave.

He stared at the battle of the Wind Howler Beast, quietly waiting, as long as he had the opportunity, he would take the opportunity to rush into the cave, as long as he entered the cave, other things would be much easier.
