The dark and treacherous shadow of the black banner shrouded over the altar, from time to time it flickered and hunted, a mysterious sacrificial power shrouded the black flag, and the ghost fires floating around continued to emit a faint green cold light, and the entire crypt was filled with an eerie atmosphere!

Looking at the black flag, which already had such momentum, Hesse's eyes were full of joy.

A black coat surrounded Hesse and climbed onto the altar, feeling the cold air coming to his face, Hesse slowly closed his eyes, and only opened them after a while.

"It's finally not in vain for my hard work!"

The Forbidden Soul Banner is almost complete, and the next step is the Banner!

Different from the banner of the Forbidden Soul Banner, Hesse obtained the most important treasure material for refining the banner rod from the beginning, the Nether Stone!

Although there is a stone character in the Nether Stone, its essence is gold and iron!

Compared to the Blue Devil Vine, this Netherstone is even more rare, and the Netherstone in Hesse's hand is even more rare immortal-level treasure!

What is the Immortal Rank Treasure Material? That is the material for refining the Immortal Rank Magic Weapon!

Hesse still has some questions, how did White Fang get such a heavy treasure and hide it under the throne?

However, considering that White Fang was also an outsider, the treasure chest was probably brought from elsewhere, and Hesse was relieved.

Who hasn't had a chance? Although in the hands of the white fangs, it is completely a pearl and dust.

Compared to the banner made of the Blue Devil Vine, the banner made of Nether Stone, Hesse consumes more energy!

Because this banner is not just as simple as serving as a support for the forbidden soul flag! it can even be said that compared to other banner magic weapons, most of the power of this forbidden soul banner is on this banner!

On the animal skin of the forbidden soul flag, there is only 30% of the length of the banner, but the banner rod is 50%, and the remaining 20% is the final melting.

According to the refining method on the animal skin, this forbidden soul banner is actually a magic weapon that is biased towards the blade, and the banner itself is a black iron spear!

This means that the Forbidden Soul Banner can be attacked and defended, and it can not only control powerful ghosts, but also use it to kill with blades!

This is also the reason why there is only one Netherstone in the golden treasure chest, and there is no treasure material used to act as a banner!

Hesse completely regarded it as a black iron gun to refine! From collecting auxiliary materials, to creating molds, about the length and size of the flag, the decoration of the gun body, these aspects, Hesse can be said to be painstaking, the pursuit of perfection!

In the process of refining the banner, Hesse encountered the biggest problem to date, that is, how to melt the Netherstone and cast it!

If it hadn't been suppressed by the black jade in Hesse's body, Hesse would not have even been able to save his life at that time, and his soul would have been sucked away by the Nether Stone!

Although Hei Yu suppressed the Nether Stone, it was not damaged, and no matter how Heisen tried, he just didn't get a response from Hei Yu, so Hei Yu couldn't count on it! And when Hesse ingested the Nether Stone into his body and quenched it with Danhuo, he was stunned to find that in the dantian, this Nether Stone directly squeezed the demon pill in his body aside, domineeringly occupied the position that originally belonged to the demon pill, and it was quite close to the center of the dantian, much stronger than Hesse's demon pill!

If you can't even get close, how can you temper it?

As for the poisonous miasma, it is extremely domineering to living beings, but when it encounters an immortal-level treasure material like the Netherstone Stone, it can only be suppressed, not destroyed!

In desperation, Hesse even used the Giant Ghost King's natal ghost fire.

This time it was even worse, the ghost spirit of the giant ghost king was almost sucked in, the soul core was cracked and almost shattered, and the natal ghost fire was sucked clean!

If it weren't for being a ghost of Hesse, the Giant Ghost King would have been powerless to resist, and I am afraid that he would have turned his face a long time ago!

And there is a method recorded on the forbidden soul banner refining animal skin, but it can only be used on the fairyland, and in ancient times, the heaven and earth had sufficient yuan, and there were a lot of fairyland realms, so it was naturally able to do it, but now it is trapped in Heissen!

In desperation, Hesse had to put this matter aside first, prepare other materials, and at the same time practice the "Nine Shadows Town Prison Gong", with the help of thousands of powerful ghosts, it took a full seven years to finally repair the prison town chapter to the sixth level, and with the help of black jade, the "Nine Shadows Town Prison Gong" was pushed to the seventh level!

Under the fairyland, "Nine Shades of Prison Martial Arts" is divided into nine layers, of which the first three correspond to the demon pill realm, the middle three correspond to the divine soul realm, and the last three are the realm of thunder tribulation!

Hesse broke through to the seventh level, which means that it is enough to trigger the thunder tribulation, if it can be crossed, it is the overlord level thunder tribulation demon in the mountains!

However, there are very few people who can cultivate to the realm of the Ninefold Small Success, and it is also difficult to survive the thunder tribulation after the sevenfold period, throughout the ages, all those who practice the "Nine Shades Town Prison Gong" have mostly died under the thunder tribulation!

All because "Nine Shadows Town Prison Gong" is the culmination of the Netherworld Ghost Dao, and the cultivation of this skill is to enter the immortal with ghosts, not the right way of the Xuanmen, and naturally be punished by the Heavenly Dao, and the thunder tribulation that is crossed is several heavier than the thunder tribulation caused by other Xuan Gong!

But after Hesse was trapped in the Nether Stone Quenching, he wanted to use the power of the Thunder Tribulation to quench and forge the Nether Stone!

And in the original of the Giant Ghost King's exercises, there happens to be a secret method that can temporarily suppress one's own Thunder Tribulation, and cultivate all the way to the supreme realm of the Nine Shadows Town Prison Martial Arts before triggering the Thunder Tribulation!

But no one has ever tried this secret method!

Think about it, too, it's just a temporary suppression, and it will eventually break out in the future!

Moreover, after using this secret method, it can be delayed for a while, but when one's own cultivation is promoted, the thunder tribulation caused by it is superimposed back and forth, and the power is even greater!

Even if you use this method to cultivate to the supreme realm of the Nine Shades Town Prison Gong, the thunder tribulation caused by it is not as simple as the ninth level!

The thunder tribulation triggered by the cultivation of the "Nine Shadows Town Prison Gong" can destroy everything by the ninth level alone, and it is not much worse than the number of tribulations that exist in the fairy realm! From the first to the ninth level, the thunder tribulation caused by it is simply terrifying, even if it is not difficult to collapse the entire Black Mountain!

Even the demon king who cultivated the "Nine Shadows Town Prison Gong" to Xiaocheng also crossed it with many difficulties, and finally triggered the ninth thunder tribulation with all kinds of preparations, but he still failed and died!

But Hesse quietly used this method to constantly suppress the thunder tribulation that should have been triggered, and with the help of the huge amount of resources and grains plundered by the Giant Ghost King and the help of black jade, he began to cultivate wildly!

The reason why "Nine Shades Town Prison Gong" is difficult to cultivate is that the Thunder Tribulation is the biggest barrier in front of all cultivators, and in addition, the huge amount of resources required for cultivation is another big problem!

Xiu Xian asked, even if you have high qualifications and extraordinary roots, but if you don't have resources, it is in vain, otherwise how can wealth occupy the first place in the wealth and law!

That is to say, the Giant Ghost King has a lot of wealth, and he has plundered the inheritance left by a number of demon kings, and obtained a large amount of resources to support Hesse's cultivation, otherwise Hessian's cultivation would have been sluggish!

Rao is like this, Hesse is still trapped in the seventh peak of "Nine Hidden Towns Prison Gong", and he may step into the eighth level at any time, but he just can't break through!

Just when Hesse was living in the crypt and concentrating on cultivating the "Nine Hidden Towns Prison Gong", the Black Mountain was already in a turbulent dark tide, with constant twists and turns!

Originally, the Black Mountain Demon Clan was already facing off from the Ziyang Dao Palace across the mountain, and the stalemate situation fell into a new turmoil because of the intervention of a demon clan powerhouse outside the Black Mountain!

This demon clan powerhouse sent his master, a demon king of the Eightfold Thunder Tribulation, to Montenegro, entered the first peak, and began to strongly integrate the demons of Montenegro to fight against the Ziyang Dao Palace!

The Blood Wing Demon King of the Second Peak, the Holy Jiao King of the Third Peak, the Li Peng King who has just entered the Fourth Peak, and the Giant Ghost King of the Fifth Peak have all received an invitation from this new Eightfold Thunder Tribulation Demon to discuss important matters at the first peak!

The Eightfold Thunder Tribulation Great Demon is still the peak strength of its heyday, and it is also the Eightfold Thunder Tribulation, which is far from being able to fight against the Bloodwing Demon King who has not recovered from his serious injuries at this time, not to mention the remaining Saint Jiao King, Giant Ghost King and Li Peng King!

What's more, there is a demon fairy behind this big demon, and it is not something that these thunder tribulation demons in Montenegro can fight against!

Whether they wanted to or not, all the demon kings in Montenegro had no choice, and they all went to the first peak one after another, preparing to meet this eightfold thunder tribulation demon!

"Do you know the origin of the Withered Dome Demon King?" Hesse asked, looking at the handwriting of the great demon left on it.

Although he had explored the memory of the Giant Ghost King, Hesse focused on the practice of exercises, and the rest of the huge memories were only cursoryly read and did not delve into it.

"I've heard a little!" the ghost fire in the eye sockets of the giant ghost king was blazing, "This withered dome demon king is among the many thunder tribulation demons, but he has been famous for a long time! In the early years, when I was not promoted to the thunder tribulation, this withered dome demon king was the best among the thunder tribulation demons, dominating the northern Daze, and later cast himself under the command of a demon fairy, about a thousand years ago, and his strength is even more unfathomable! Compared with this one, the blood wings and fire Jiao are considered juniors!"

"And the fairy?" asked Hesse.

"That's not what I know!" the Giant Ghost King shook his head, "This demon fairy has always been mysterious, and he is not as famous as other demon powerhouses, and he has never even been famous!"

Seeing Hesse fall into a deep groan, the Giant Ghost King asked after a long time, "Then do you want to go this invitation?"

"Of course I want to go!" Hesse looked up at the Giant Ghost King, "not only to go, but also to go there in person!"

"The time agreed on the invitation is tonight when the moon is in the middle of the sky, and I want to come to other demon kings to go, but it won't be too positive, this is our chance!"

"This withered dome demon king has come all the way to this black mountain, and he does not hesitate to fight head-on with the Ziyang Dao Palace, except for the seal of the mountain god, what else is worth him doing?"

Hesse said with a smile, "It's just that the Mountain God Seal is missing, and this person's top priority is to find the Mountain God Seal, at least not to let the Ziyang Dao Palace get the Seal!"

"And at this time, this one needs a local snake who is familiar with the things in the mountains, to help him find the seal of the mountain god, and quickly open the situation! The Bloody Wing Demon King is an eightfold thunder tribulation demon, even if he is seriously injured, but the background is still there, even if he is effective, that one must not be at ease! And although the Holy Jiao King has lost his body and his strength has been greatly damaged, he has a rebellious personality, and naturally he will not give in! King Li Peng originally collected the demon clan in the mountains, and when the other big demons were all cultivating, he was faintly the leader of the demon clan of the Black Mountain, and his power was incomparable, but he was intervened by this side, so he naturally would not be reconciled! In contrast, you, a great demon with only six strengths and no conflict of interest, are the most suitable to become the head snake of this land! As long as you surrender, that one will definitely accept it!"

Seeing that the Giant Ghost King showed a hesitant expression and was silent, Hesse said with relief on his face: "It's rare for you to be so sensible, since you have acquiesced, just prepare to prepare! Hey, I've really wronged you!"

The ghost fire in the eye socket of the giant ghost king almost exploded, and he was speechless for a long time!

"When did I say yes?"
