The speed of Nangong Wushuang's westward journey was not very fast, first, he intended to cultivate the Ten Heavenly Stems, and along the way, Nangong Wushuang made them experience bloody battles again and again, so as to hone themselves, and at the same time, he also took out countless precious treasures to baptize their bodies and strengthen their foundations again and again.

More than a month has passed, and the ten heavenly stems have become stronger by more than three or four times, and Nangong Wushuang has privately chosen two invincible methods for them, one for refining the body and one for martial arts.

However, the stronger they become, the more they find themselves and the bigger the gap between them and their landlords.

The second is that Nangong Wushuang wants to take this opportunity to destroy some forces, these days, there are no less than thirty forces that have been destroyed, of which more than a dozen are his suppression of the formation, the Phoenix King's shot, and the rest are the masterpieces of the Ten Heavenly Stems.

They had planned to go down the Yellow River all the way, but a few days ago they crossed the Yellow River and came to Yanzhou.

Because halfway through, he got the whereabouts of a force called Heavenly Demon Castle, which was a huge force that disappeared forty years ago, and at that time it could rank among the top ten of all forces.

Its founder's name is Ape Evil Heart, before it disappeared, its helmsman was the son of Ape Evil Heart, the Ape King, and the strong man who sat down had thirteen Taibao, all of whom were very strong, as for what the current situation was, it was not too clear.

However, he didn't come this time to destroy the Heavenly Demon Castle, but for one thing.

Today, after Nangong Wushuang sent the Ten Heavenly Stems out on a mission, he took the Phoenix King to the location of the Heavenly Demon Castle according to the news he received.

Shazhou, one of the nine small states of Yanzhou.

It is also one of the ten largest states among the eighty-one small states, with countless forces, and it is also one of the small states with the most murderous places, the most famous of which are Death Valley, Blood Spirit Mountain, Thunder Valley, and Hell Mountain Range.

Among them, Death Valley is listed as one of the top ten forbidden places, and the Heavenly Demon Castle is hidden in Death Valley.

Death Valley, located in the far west of Shazhou, is in a sense not a valley, but evolved from a small broken cave.

In ancient times, this cave was occupied by a big Luo Jin Immortal named Lei Tianzhenren, when his limit came, in order to seek immortality, he let go of it, and integrated his Taoism and Yuan Shen into this cave, wanting to have a cave heaven immortal, he would live forever, but he finally failed, and the small cave was destroyed together.

This has also led to the year-round thunder and lightning in Death Valley, a barren and lifeless place, and few people dare to set foot in it.

When Nangong Wushuang and the Phoenix King arrived at Death Valley, it was already two days later, and when they saw the scene of Death Valley from a distance, even Nangong Wushuang was secretly shocked.

This is an unusually broken world, filled with the atmosphere of desolation, there are endless thunder and lightning raging, fiercely bombarding the earth, tearing out the ravines like an abyss, as if there is no end, such endless darkness, creepy.

But what makes people's scalps tingle even more are those black thunderbolts.

"It is worthy of the Dao of Da Luo Jin Xian, more than 100,000 years have passed, and it still hasn't dispersed, and it's still so terrifying!" King Huang whispered, his face showing surprise.

Especially when they saw that in the distance, the thunder and lightning were as thick as mountains, and with every blow, smoke and dust swept away, and mud and stone boiled.

"Would the Heavenly Demon Castle really be hidden in this place?" The Phoenix King was a little skeptical about the accuracy of the Hundred Insect King's news at this moment.

The entire Death Valley is in an extreme depression, not feeling the slightest spiritual power of heaven and earth, and the surroundings are so destroyed that they can't live there, not to mention that the power of thunder is everywhere, which makes people's hearts beat.

"Let's go! Since you're here, let's go in and take a look!" After pausing for a moment, Nangong Wushuang smiled lightly and took the first step into the Valley of Death.

"You just need to stay by my side," Nangong Wushuang turned into a large umbrella with spiritual power and suspended it above his head, isolating all thunder and lightning.

"Such a place can be described as a real Jedi, even if the powerhouses at the peak of the Immortal Realm come, they don't dare to go far inside," the Phoenix King said;

"These thunderbolts also contain extremely weak power of the law, once they are hit, even if they don't die, they won't have long to live," Nangong Wushuang said with a solemn expression;

"Laws?" The unfamiliar noun made King Dehuang frown.

"The law is a deeper control of the Great Dao," Nangong Wushuang explained casually, not intending to talk about this topic in depth.

"If the Heavenly Demon Castle is really hidden in it, then how did they avoid these thunderbolts, and how did they survive inside?" The more she walked inside, the more the Phoenix King felt that her scalp was numb, even if she was supported by Nangong Wushuang all the way, she was still a little frightened.

"I'm also a little curious about how they dodged these thunderbolts and how they survived inside!" Nangong Wushuang said with a smile;

"What is the purpose of the Kyushu Ding? It is worth your effort!" After a long time, the Phoenix King asked the confusion that had been hidden in her heart for a long time, and she knew that Nangong Wushuang did not hesitate to cross the Yellow River and rush to Yanzhou, just for the sake of the Kyushu Ding.

"Kyushu Ding...... ，”

Nangong Wushuang hesitated for a moment and said, Kyushu Ding is a holy relic condensed from the origin of this heaven and earth, if it can be gathered and refined, then it will be able to control part of the power of the origin of heaven and earth, and even the Heavenly Dao will not be able to help him at that time, because the Kyushu Ding is the condensed origin of heaven and earth to restrain the Heavenly Dao.

"If you get three more Heavenly Books, then you will have the opportunity to become the master of this world, and the Heavenly Dao will have to stand aside," Nangong Wushuang added;

King Huang was shocked, she didn't expect Kyushu Ding to be so involved.

"However, the first and second holy relics condensed from the origin of heaven and earth are not the Kyushu Ding," Nangong Wushuang said suddenly;

King Huang subconsciously asked, "It's not Kyushu Ding, what is it?"

"The first one is the Sky Opening Axe!" Nangong Wushuang Road;

He continued, "Everyone knows about Pangu's opening of heaven and earth, but not many people are involved in it, and this involves the control of the origin of heaven and earth. ”

"However, once Pangu becomes the master of this world, the life and death of all living beings in this world are in his thoughts, and even the Heavenly Dao can only be at his mercy, but the Heavenly Dao cannot tolerate such a thing, so he calculated Pangu,"

"What is the Heavenly Dao? Is it a living being? Is it just or evil?"

"In fact, the catastrophe of opening the heavens also involves a secret matter, the way of heaven is the will born from the origin of heaven and earth, it stands to reason that it is the rightful ruler, and it is also a ruthless, desireless, fair and selfless law enforcer, but when the will was just born in this world, it was manipulated,"

"Because this world is not trivial, there are people outside the world who have long been eyeing it and want to control it, so they planted a soul mark in the still weak origin will, so as to help refine this world in the future,"

However, at that time, there were also people who did not want this world to be controlled by evil people, so they did something in secret, at that time, because the origin of heaven and earth could not give birth to a second will, so with the help of that person, they condensed the Heaven Opening Axe and the "Chaos Heavenly Scripture" that was divided into three heavenly books, and at the same time chose Pangu, so that he could balance the Heavenly Dao that was planted with a soul mark, and even destroy him.

Nangong Wushuang told some of the secrets of the ancient times, and the Phoenix King looked sluggish when he heard it.

"But it's a pity that Pangu still fell under the calculation of the Heavenly Dao after all," Nangong Wushuang sighed and said, Pangu Axe is nowhere to be found, if I can find Pangu Axe, then I don't have to work so hard.

"What is the second holy relic condensed from the Heaven and Earth Origin?" the Phoenix King asked;

Nangong Wushuang glanced around and said casually, Donghuang Bell, also known as Chaos Bell.

He then explained: After the fall of Pangu, the origin of heaven and earth directly separated a wisp of origin and evolved into the indestructible Donghuang Bell, and at the same time helped the earliest wisp of divine thunder born in heaven and earth to give birth to consciousness, making him the second Pangu ,......。

Are you talking about the Eastern Emperor Taiyi, who was born around the Eastern Emperor Bell? Before Nangong Wushuang finished speaking, King Huang exclaimed;

"Yes, that's also a poor buddy, and he also fell under the calculations of the Heavenly Dao," Nangong Wushuang smiled bitterly;

"Then is the real purpose of your journey west related to him?" the Phoenix King asked, as if he had thought of something, turning his head to look at him;

Nangong Wushuang nodded, but didn't say anything, and King Huang didn't continue to ask.

When night was approaching, Nangong Wushuang suddenly stopped his pace, he had searched for most of this Death Valley, but he still hadn't found the location of the Heavenly Demon Castle.

"Could it really be that the news of the Hundred Insect King is wrong?" Nangong Wushuang frowned, what is the ability of the Hundred Insect King, he still only knows, and he has never made a mistake so far, so at the beginning, he was convinced of the news of the Hundred Insect King, but now, he is a little suspicious.

"If the Heavenly Demon Castle is really hidden in it, then ...... These thunderbolts should be their best protective umbrella......" Nangong Wushuang's eyes narrowed slightly, looking up at those unscrupulous thunderbolts.

"What do you think of?" asked the Phoenix King, stunned for a moment;

"What if...... These thunderbolts are gone, so do you think they will show up to stop them?" Nangong Wushuang seemed to be talking to himself, and his voice was very soft.

"......"

"Is there a way for you to make these thunderbolts disappear?" asked the Phoenix King after a pause;

"Hehe, what's so difficult about this landlord?" Nangong Wushuang smiled evilly and said, "Just watch the landlord show his might! Let you see the power of the landlord, don't always go against me in the future."
