Han Xing knocked on the bones of the dragon carp and the crocodile, and made a sound as brilliant and hard as black steel and fine iron, "Bah", the sound came out, and even the rocks on the riverbed below turned into powder under the shock.

"Impossible, the bones of these two fierce beasts have survived at the bottom of the river for a few years, and they have become rotten bones, how can this situation still occur?"

Looking at the two skeletons that were as white as jade, he suddenly remembered that in the book "Treasure of the Great Wilderness" left by his father, it was recorded that most of the bones with this kind of holy light were left by the Demon Sanctuary, which was a miracle material that could be refined into a peerless weapon!

If the bone powder inkstone is subdued, it can change the person's physique and achieve the body of the keel!

A bone is hard to find, and a large nail is worth ten thousand gold!

"What else do you see, such a good refining material is hard to find, send it, accept it first!" After everyone retreated and left, Han Xing waved his hand and collected the bones of these two ancient barbarian beasts into the bronze tripod.

Unconsciously, the sky above the Jiuqu Heavenly River has completely covered the sun, and the sky is extremely dark, and the sky is full of stars at all times.

I saw that the Big Dipper seemed to be pulled by an inexplicable force, and gradually moved one by one, forming the momentum of the Big Dipper shining on the moon, reflecting the starlight of the seven stars directly to the bottom of the river.

At this time, in the depths of the riverbed, it seemed that under the traction of starlight, a monstrous energy fluctuation suddenly surged, and the vast force seemed to swallow up the entire river.

Suddenly, the aura of heaven and earth swept over and surged to the bottom of the abyss of the dragon trough......

"Look ahead!" Han Xing pointed ahead.

Everyone saw that in the deepest part of the river there was a dim depression, on which there were two huge stones, like a heavenly monument and a dragon's head, standing in front of everyone.

The boulder is magnificent, as if it has stood here since ancient times.

When I swam closer, I saw that it was even more hideous, and two huge stones set up an arched stone door, like the mouth of a giant beast devouring the sky and the earth, and it seemed to be through the netherworld.

The whole body of the boulder is shrouded in a faint layer of black-red water mist, and each of them is engraved with a word, but together it is the word "dragon trough".

These two words were bloody, like the giant eyes of a dragon, emitting an extraordinarily bright red light, flickering with the fluctuation of the river.

Under the reflection of the red light, the deep ditch on the entire riverbed, as if it had come to life, outlined the figure of an ancient dragon, lying at the bottom of the Jiuqu Heavenly River, with its head held high, like breaking the sky.

"Zhenhe Stone!"

Nangong Heng couldn't help but be stunned, and exclaimed: "Legend has it that there is a town river stone under the Jiuqu Heavenly River, but I don't know that it is a huge stone engraved with the word 'dragon trough' in the legend, but I don't know why this town river stone is so strange?

"Everyone be careful, gather together, don't scatter!" Han Xing saw the danger here, and while reminding everyone, he said to Nangong Heng: "Senior brother, you protect everyone, and it's not too late for me to come forward to find out the situation, so as not to wipe everyone down!"

Nangong Heng's heart sank, in the face of danger, Han Xing wanted to put himself to death, but he did not hesitate to leave his life to others, but what he wanted to protect was the brothers of the Longyuan Sect who had only known him for a short time!

This shows that this person is enough to be a brother!

Nangong Heng did not stop him, the more dangerous he was, the more he experienced people, and it was not too late to take action when he was in danger.

He smiled, with Han Xing, he had a feeling of life and death as a brother!

Han Xing quickly approached the front, only to see the wreckage of countless ships scattered in the mud around the boulder, huge fish bones and some unknown skeletons stretched out at will, and white bones could be seen everywhere......

There are also dense terracotta figurines fired by ancient ancestors, half-buried in it like dead people, making this place full of a suffocating atmosphere, which is obviously a remnant of the sacrificial seal.

The strange thing is that on these two hard boulders, there are some marks of slashing and axes and traces of giant teeth biting, which is extremely weird.

Each boulder was bound by four bucket-thick steel cables, which shimmered black and cold.

The other end of the eight iron cables extends along the arch-like gap between the two boulders, just like the eight dragon-binding ropes have locked the leylines, and I don't know how many miles they have entered, as if they are hooking and suppressing something inside.

The cracks in the arched doors overflow with colorful light, forming a blue light curtain barrier to block the intrusion of the rolling river.

Han Xing was shocked and shouted, "This is the entrance to the passage of the Ancient Secret Land!"

All the people were overjoyed and burst into tears, it turned out that this was not a legend, but the existence of the human world that really led to the ancient secret land - the secret path of the dragon trough.

At this moment, the vision here had already attracted the attention of all the monks of all sects and sects who participated in the trial.

For a moment, whoosh ...... All the people are like a school of sardines, gathering here with lightning speed.

Han Xing gradually approached the depression in the gap between the two boulders, where the whirlpool was amazing, and he looked through the blue light curtain, and sure enough, at the bottom of the depression, there was an irregular hole the size of a stone house.

At this moment, the starlight of the seven stars in the sky above the Yellow River became more intense, corresponding with the blue light curtain barrier at the entrance of the cave, and the surroundings became brighter and brighter.

Suddenly, there was a faint sound of rock cracking from the cave, and the eight black steel cables also trembled, and a huge reaction force along the iron cables came out of the hole, as if something was about to break, vibrate and break the iron cables, and rushed out.

The sudden change made the two boulders outside the cave suddenly change color, turning from dark black to reddish-brown, and the whole body seemed to be infected with blood and water, producing bursts of coercion, and the strong bullet pressed the momentum from inside the cave to the outside.

Under the combined pressure of the two forces, the river formed a huge whirlpool, and began to surge, like a mountain and a sea, rushing and roaring.

Several three or four zhang long brocade carp and more than ten zhang long lead-colored water snakes were instantly torn to pieces by the huge pulling force of the whirlpool.

This breath made everyone breathless, causing people to burst their liver and gallbladder, and everyone was drenched in cold sweat and their hair stood on end.

Outside the boulder, although the whirlpool is amazing, as long as it is a yellow-level fighter, it can easily fight out. And within a hundred zhang, the whirlpool surged out in a circle from the blue light curtain at the entrance of the cave, and the white foam erupted, even if it was a strong person in the War King Realm, he didn't dare to stay for a moment.

Han Xing only felt that his qi and blood were surging, and under this kind of coercion, his limbs seemed to explode inch by inch, and the range of the whirlpool was rapidly expanding outward.

"Stand back!" Han Star shouted.

Suddenly, an overwhelming force rushed over......

"Not good!" At the critical moment, Han Xing let out a long roar, and a golden Kunpeng phantom appeared behind him, and he used the "Kunpeng Void Technique" "Diving Yellow Spring" trick, turning into a streamer and rushing towards the disciples of the Longyuan Sect who were hundreds of zhang away.

At the same time, with enough mixed Yuan True Qi, his right hand formed the "Immovable Fundamental Seal" in "Nine Seals Against the Sky", and turned into a void mudra with a "whew" and shot it out with all his might.

"Boom" is more than 100 zhang apart, and the two monstrous forces collide violently, and the momentum is shocking.

The powerful mana fluctuations spread far away, and the turbulent waves rushing in front of them were surged into the sky by the unrivaled palm power, and the fierce whirlpools were blocked by the vortex surging backwards, separating to both sides, rushing away.

The situation is chaotic......

All the disciples of the Longyuan Sect were stunned, if it weren't for Han Xing's quick reaction, he would have stopped the tearing whirlpool like a sharp blade as soon as the shout fell, I am afraid that they would have been twisted into a pile of meat residue by now!

At the same time, the whirlpool was surging, the water waves were flying in all directions, and the purple exercises like sharp blades were layered on top of each other, one after the other, and they rushed towards the disciples of the other sects who did not avoid it.

The waves were surging, several ups and downs, and everywhere they went, many monks were thrown into the sky by it, and then fell into the whirlpool waves to be torn and crushed.

Thousands of people avoided it, as if they were in the midst of thousands of blades!

Amid the wailing and screaming, thousands of monks were lifted more than a dozen feet high and then smashed into the whirlpool.

At this moment, the whirlpool is like a meat grinder that devours the sky and the earth, and even the swimming fish in the water are not spared.

In the face of the terrifying power of the rivers, lakes and seas, the monk's personal strength seemed quite small and vulnerable!

Suddenly, endless blood stained the entire river red.

Countless heads, stumps, and half of the body spun rapidly in the vortex.

Batch after batch, like a giant whale devouring shrimp......

More than 10,000 monks who entered the dragon trough stream were suddenly torn and strangled, and more than 5,000 people were killed, and the water became empty in a moment.

The whirlpool that resembles a sharp blade tears and kills 5,000 people in an instant!

The people who didn't die were all stunned and completely stunned!

The next moment, I'm afraid that everyone will not be spared!

Just when everyone was desperate, the heavenly dog in the sky above the Jiuqu Heavenly River devoured the sun and had become a great consummation.

After a while, the black moon moved slightly, revealing a little gap in the sun, and the dark and hazy void gradually became clearer, and the light of the Big Dipper shining on the bottom of the river also weakened.

As soon as the starlight traction disappeared, the entire whirlpool swirled sharply, and the monstrous undercurrent, under the overwhelming sound of smashing, finally dispersed, completely merged and dissipated into the surging river.

There was a great uproar all around, and as the whirlpool disappeared, it suddenly became a dead silence.

No one spoke, and the disciples of the Longyuan Sect knew in their hearts that it was Han Xing who saved their lives!

Nangong Heng felt as if his heart was about to stop beating. "Why is this whirlpool so ferocious?" he asked, shocked.

"I saw in a trance that seven beams of starlight were thrown into the river, which caused this disaster!" Han Xing was also shocked by the tragic scene in front of him, he didn't think about it, and blurted out.

Nangong Heng's heart moved, and he said: "This may be the outer prohibition of the secret path, just to prevent people from advancing, it should be set up by that saint to divide the two realms." ”

He looked carefully, and found that the blue hazy light mask at the entrance of the cave had formation fluctuations, and it was these formations, moved by the starlight, that formed a large array, making it impossible for people to approach the entrance of the cave, and as soon as the starlight weakened, the vortex of the forbidden large array naturally disappeared.

With the power of one palm, Han Xing was able to resist the power of heaven and earth gathered in this large array......
