Yuan Kunyi, the great elder of the cross-border business alliance, respectfully and movingly took the yīn yangqin and accepted the old man's brief transmission guidance.

In this moment, of course, it can't allow Elder Yuan to fully master the manipulation of the yīn yangqin and exert all its power, but it can be done to exert thirty percent of its power.

Yuan Kun flew over the city wall with the yīn yangqin, and in the face of countless demonic beasts with teeth and claws, he snorted lightly in his nose, a sneer appeared at the corner of his mouth, and his eyes flashed!

Suddenly, his mana was released, and a faint square ruler-like void enveloped his whole body, which turned out to be an extremely rare treasure void shape, that square ruler void shape, like a bottomless whirlpool, frantically absorbing the surrounding heaven and earth demonic energy, making him feel great for a while.

"Zheng~" Yuan Kun stretched out his fingers vigorously, and a pleasant piano sound sounded, in this noisy environment, like lightning in the dark night, clearly transmitted thousands of miles without weakening, at the same time, a visible sound bō, rippling in front of the dàng, forming a bōlan-like space bō movement, facing the demonic beasts coming from the pavement.

"Puff" several times softly, these several magical beasts, without any suspense, shattered into a blood mist in the sound bō, there is no resistance at all, among which the highest cultivation is already the late stage of refining the void, which shows the terrible sound of bō.

Yuan Kun took a big breath, lifted the mana around his body, and his ten fingers continued to bō on the strings like electricity, popping out a sometimes beautiful, sometimes terrifying piano sound, and at the same time, layers of sound bō dispersed in front of him, emptying all the demonic beasts in the miles in front of him, and the demonic beasts in this range, no matter what they cultivated, all turned into a blood mist, and none of them survived!

The sound of the piano is sometimes as melodious as the rumored fairy music, and the natural sound is fascinating, making people feel as if they are in the wonderland of the fairy palace, and sometimes it is like a ghost crying wolf, and the yīn forest is terrifying, giving people the feeling of being in the ghost mansion of Huangquan. The two tones change suddenly, as if isolating yīn yang.

Although the main power of the yīn yangqin was spread among the beasts in front of it, the human monks under the city walls were also somewhat bō.

Some restless monks failed to block their ears in time, and the sound of the piano entered their minds, and then they involuntarily moved with it, sometimes dancing, intoxicated, and sometimes frightened, hiding their faces and crying. The high-ranking monks around them injected them with a series of tricks in time to help them stabilize their minds, and only then did these people wake up and immediately block their ears, never daring to listen to the sound of the piano again.

As for those demonic beasts that have not yet been enlightened, they were either directly killed by the sound of the music, or they were gradually lost in the sound of the qin, and in the eyes glowing with red light and madness, the gods gradually became confused, and many of them were even floating in place, just dancing with their hands.

The sound bō can kill the demonic beasts within a few miles, but the sound of the qin spreads extremely far, within a radius of thousands of miles, the impact of the demonic beasts is suddenly alleviated a lot, and the human monks here are also slightly relieved in their hearts while guarding their ears.

"A song is broken, where to find the fairy road at the end of the world!The yīn Yangqin is really extraordinary! It's a pity that Kun Yi can't display the full power of this qin!" The young man surnamed Jia nodded slightly and sighed lightly. With his cultivation, he will naturally not be affected by the current sound of the qin, but from the sound of the qin, he can hear the meaning that the fairy road is difficult to find, that it is often cut off, and that yīn yang is separated.

The power of the yīn yang qin, of course, is more than that, if it is performed by yīn yang zhenren himself, just three or two clicks of the qin can firmly grasp the mind of the demonic beast within a radius of thousands of miles, and in turn use it for the human race.

Yuan Kunyi continued to use the yīn yang qin for only dozens of breaths, and it was already a huge loss of mana, and his breath was quite chaotic, and at this time, there were also many demonic beasts that were completely controlled by the sound of the qin, not only no longer rushing towards the human race, but fighting with those demonic beasts that were still crazy.

Suddenly, "woo~" A long and far-reaching horn sound came from a distance, making Yuan Kunyi's heart jump wildly involuntarily!

Fortunately, those Terran monks had already blocked their ears, but there were still many people who felt a sudden burst of panic and restlessness!

And those wild beasts, in the sound of this horn, were released from the sound of the piano one after another, as if they had just woken up from a dream, and rushed towards the human monks more and more frantically!

"Distant Ancestor Horn!They really used this treasure!" Yīn Yang Demon Monarch sighed and shook his head slowly, a little helpless.

"The Distant Ancestor Horn, the genuine treasure of Xuantian, the treasure of the Beast Clan's Zhen Clan, was actually brought to this battle by them, it seems that in this battle, they really plan to ask our human race to withdraw from the Shengyuan Continent!" The young man's eyes shrank, and his brows furrowed slightly.

The one who blew the horn of the distant ancestor just now was also a combined late-stage beast cultivator, and he also only showed a little power, otherwise with the terrifying power of the Xuantian Treasure, I am afraid that the low-level cultivators of the human race would immediately suffer heavy losses.

"It's a pity that the blood godless god is still closed for a thousand years, otherwise with the Xuantian Treasure Drinking Immortal Sword in his hand, we still need to be afraid of those beast clan old monsters!" the young man said with a regretful sigh.

"Hey, although the Blood Void God is the highest cultivator among the Mahayana monks of the Terran Race such as me, he has always been independent and has never taken the revitalization of the Terran race as his own responsibility, even if he is not in retreat, it may not be easy to ask him to help us fight!" Yīn Yang Demon Lord still shook his head and said, as if there was no way to deal with it now.

The young man knew that the old man's words were already very polite, but in fact, the bloody and godless person was not profitable, quite sinister and vicious, and murder and treasure hunting happened from time to time, but he was not interested in developing and maintaining racial power at all. After all, for an existence like him that can vertically and horizontally demons, the power is already like a floating cloud, and it is of little significance.

More and more demonic beasts rushed to the vicinity of the city wall and started a fierce battle with the Terran monks.

The demonic beasts are simply endless, and the warships and chariots of the Terran monks, as well as the means of ironclad warriors, corpse refiners, and blood demons, are gradually being consumed, and if one is destroyed, one is missing, and there is no replenishment.

As for those Terran monks who fight against demonic beasts with their flesh or treasures, they may fall at any time. For a while, although the human monks were still killing the barbarian demonic beasts with extremely high efficiency, their own consumption was also extraordinary, and the battle situation became more and more tragic, the destruction of every warship and chariot, and the tearing of every monk by the demonic beasts, all made the human race have some less chance of winning, and made the surrounding monks feel worried.

This is a very unfavorable situation for the human race, because the most terrifying beast clan monk team has not even appeared, and the wild beast beast herd has no end in sight.

"The battleship retreats and opens the formation, we can't afford to withstand such consumption!" said the Yang Demon Monarch helplessly.

"Start the big array now, in the face of so many demonic beasts, I'm afraid that if you can't hold on to the appearance of the beast clan monks, you will be attacked!" said the young man with a frown, although he said this, he also knew that the situation was compelling, so he reluctantly gave the same order.

After a violent bombardment, all the warships flew back to the vicinity of the city wall, and the remaining chariots, only two-thirds, were all withdrawn behind the city wall.

In a mysterious stone hall on the inner side of the city wall, Zheng Lin and dozens of other formation grandmasters had already received orders, and each of them hurriedly played out one magic trick after another, and disappeared into the various array eyes of the dragon pan star array in front of him.

With their manipulation, countless golden light spots lit up on the array disk, as if the night sky was full of golden stars, which was very gorgeous. The real dragon graphics playing on the background of the array plate are also vivid and lifelike.

At the same time, all over the entire Heavenly Trench City, some on the ground and some in the sky above, bursts of incomparably brilliant magic lights emerged, and these magic lights intertwined in a moment, forming a huge light shield that enveloped the entire Heavenly Trench City.

The light mask exudes a faint gorgeous brilliance, giving people a sense of etherealism, and those faint brilliance converge together, and even faintly form countless five-clawed true dragon forms that are circling and flying, which makes people know at first sight that it is not trivial.

Countless demonic beasts rushed to the vicinity, wantonly attacking all kinds of spells, pillars of light, flames, hurricanes, poisons, claw shadows, ice picks, etc., all at the humans on the city wall, but these attacks, without exception, were intercepted by this layer of faint brilliance, and could not penetrate deeply!

There were even some attacks, which were swallowed by the brilliance of the true dragon form hovering on the light mask, and then spit out again, attacking those demonic beasts instead.

As soon as the Longpan Xingchen Great Array, which is known as the first defense array in the demon world, opened, the Terran monks were immediately safe and worry-free, and they received orders to use the cover of the formation to use various long-distance attack methods to kill the demonic beasts as quickly as possible and delay the consumption of the large array.

Such a large array, the consumption of magic power can be described as amazing, although this formation can absorb the demon qi of heaven and earth from a large range around it on its own, and replenish the magic power, but it is still not enough to support the consumption of the magic circle. In a certain mysterious stone hall, it is where the main magic power array of this formation is located, and the two Terran monks are constantly embedding one by one of the best magic crystals into a huge magic crystal trough that can hold more than a thousand crystals, and taking out and replacing the magic crystals that have consumed the demonic qi.

The light shield of the dragon pan star array jī can not enter or exit, and all the attacks of the demonic beasts are blocked, but the various means of the human monks can still be easily sent out of the array, constantly killing the demonic beasts.

The warships were in full swing, the chariots were spewing pitch-black flames that intertwined into a sea of fire, the Dark Light Magic Mirror shone out deadly pillars of black light everywhere, and all kinds of spells kept hitting the outside of the great array, killing the dense demonic beasts into wisps of smoke in the blink of an eye.

Those means, which are only suitable for close combat, have been temporarily recuperated. On the city wall, almost all the monks are casting spells, manipulating, and killing demonic beasts on the verge of madness!@.
