Ye Ziyu was taken aback by Nanshuang's sudden move, and a burst of girl's unique body fragrance came to her face, like an orchid and a musk deer.

Nan Shuang stared at Ye Ziyu with wide eyes, and said in a low voice, "Are you really stupid, or did you do it on purpose?"

Ye Ziyu's mouth was blocked by Nanshuang with her small hand, and she could only barely squeeze out a wry smile and look at Nanshuang at this time.

Nanshuang glanced around vigilantly, and after not finding any movement, she slowly withdrew her hand.

She glared at Ye Ziyu fiercely, and then said, "The Northern Stygian Sea is one of the Twelve Ancestral Courts, and it is also the birthplace of the Demon Clan's Holy Ancestor.

Ye Ziyu's heart sank, Nanshuang had heard such a statement from Chen Mo and Li Yuanxi as early as before.

It seems that when the cultivation reaches a certain level, there will be many incredible mysteries.

The true one is like the heavens, omniscient, omnipresent.

After a while, Ye Ziyu came back to his senses, looked at Nanshuang and hugged his fists and said, "The rough people in the mountains and fields don't understand the rules, thank you Miss Nanshuang for mentioning it."

Nanshuang glanced at Ye Ziyu meaningfully, and the words that there was a fish in the north just now, Nanshuang always felt a little familiar, but for a while she couldn't remember where she had heard it.

Regarding Ye Ziyu's identity and origin, Nanshuang has always had doubts in her heart, but the other party is unwilling to elaborate, and she didn't see what evil intentions Ye Ziyu harbored at the moment, so Nanshuang didn't ask any questions.

After all, everyone has their own secrets, and as long as they don't endanger themselves, there is no need to get to the bottom of it.

So in the face of Ye Ziyu's thanks, Nanshuang just nodded slightly.

Then he said, "How? Do you want to go with me in the Northern Sea of Stygian that I just mentioned?"

Ye Ziyu groaned, "I don't know how far the North Stygian Sea that the girl said is from where we are?"

Nan Shuang roughly calculated the distance in her mind and said softly, "Nine million miles."

Ye Ziyu nodded, and was about to ask other questions, when he suddenly realized that something was wrong.

He turned his head sharply to look at Nanshuang and screamed, "Million miles?"

Nanshuang saw that his appearance was really a little better, and couldn't help pursing her lips and laughing, "Yes, nine million miles."

Ye Ziyu's face suddenly darkened, although their speed was not slow, they could travel thousands of miles a day.

However, it's not tens of thousands of miles, it's millions of miles, if they really fly over by themselves, they have to fly to the Year of the Monkey and the month of the horse, with Ye Ziyu's current cultivation lifespan, I'm afraid that they will die of old age halfway through.

Nanshuang coughed lightly twice, and then she barely stopped laughing.

Ye Ziyu asked with a bitter face, "Girl, I'm afraid you have to go to the Northern Underworld Sea by yourself, I don't have such a long life, I can cross millions of miles."

Nanshuang's eyes narrowed into a pair of crescent moons, and she smiled, "What do you think of the demon world? It's a vast area, but it's not as wild and primitive as you think."

Ye Ziyu said, "Oh? Could it be that there is a teleportation array that is very long-range?"

Nan Shuang was obviously stunned when she heard the words teleportation array, and only after a while did she shake her head and say, "No."

A look of disappointment flashed in Ye Ziyu's eyes, Nanshuang smiled mysteriously, and continued, "You'll know when the time comes, and you won't let yourself fly anyway."

Suppressing the doubts in his heart, Ye Ziyu and Nanshuang discussed matters related to the itinerary again.

In the end, the two decided to set off in ten days and move along the North Canggu Forest towards the center of the demon world.

After passing through the Sunset Ridge in the mouth of the Southern Frost and arriving at Frostmoon City, it is not far from the Sea of Northern Styx.

The moon was like a tide, and the flesh and blood were burning in the fire, and from time to time there was a few snorts of grease explosions.

Fortunately, it is located in the dense forest, and it is the edge of the ancient forest, and the occasional passing demon beast will also be driven away by Nanshuang, although the movement of burning the corpse mountain is not small, but it has not attracted the attention of the demon clan at the level of demon generals.

The mountain of corpses was burning, and by the fifth day it had burned two-thirds of it, and now there was only a small mountain of corpses as high as a bag of earth, because it was

A sinkhole was dug, so there were more corpses piled up at the bottom, and the burning rate slowed down a bit.

At noon one day, Ye Ziyu was sitting cross-legged on the edge of the river meditating on Qi refining, and after being familiar with the spiritual power of the Demon Realm, he could already gradually feel that it was not far from breaking through the eighth layer of Qi refining.

The spiritual power in the body gathers, and the true qi in the meridians rushes like a river.

Ye Ziyu closed his eyes and concentrated, and once again tried to use his true qi to impact the bottleneck of the eighth layer of qi refining.

True Qi turned into a surging stream of water, impacting the pass in front of him again and again, Ye Ziyu's abdomen flashed with white light, and from time to time there would be bursts of thunder like waves crashing on the shore.

Nanshuang was leaning against a big tree on the cliff at this time, looking at Ye Ziyu who was sitting by the river below, Nanshuang nodded secretly.

Although Ye Ziyu's cultivation was only at the seventh level of Qi refining, his real combat power was comparable to that of a foundation building cultivator.

There is no doubt about this, Nan Shuang, who fought in the Black Marsh, knew very well that if it was an ordinary seventh-level Qi Refiner, she didn't even need to take action personally, and that Black Marsh Golden Toad alone was enough to kill Ye Ziyu.

For monks, the improvement of cultivation is the most important thing, if Ye Ziyu's cultivation can break through, then this trip to the North Underworld Sea will also be a little more certain.

Nanshuang pondered for a moment, the spiritual power in his body surged, and his body turned into a black shadow into the mountain forest, moving around and patrolling, and finally chose a commanding height on the top of the mountain, scanning the surroundings to prevent a demon beast from intruding by mistake.

The most taboo thing to break through in cultivation is the interference of external factors, which can be seriously injured at least or gone mad.

Cultivation is only subtle and subtle, and there is no room for mistakes.

It is precisely because of this that all the children of the great sects will enter the quiet place of the sect when they break through without outsiders disturbing them.

The core disciples should have elders to protect the Fa, in addition to preventing interference from foreign objects, but also to prevent those who break through from going astray.

The breeze blows in the face, blowing ripples along the river.

Ye Ziyu's mind was completely immersed in his body, and his true qi accumulation was already very full, and the breakthrough at this time was completely natural.

With a bang, like a muffled thunderstorm, Ye Ziyu's abdomen shrank and gradually disappeared into his body.

There was a ray of joy in the beautiful eyes of Nanshuang on the top of the mountain, and it was done.

Ye Ziyu breathed for a long time, and did not rush to get up, his mind continued to immerse himself in his body, feeling the subtle changes after the breakthrough.

Big and small Zhou Tian, the eight veins of the Qi meridian, and now only the last Yang Wei vein is still in a state of occlusion.

As long as you open up the Yang Wei vein, you can reach the ninth layer of qi refining, and after the nine layers, you can integrate through the hundred veins, which is the tenth layer of qi refining.
