At this time, the Great Red Sword Emperor was staring closely at the skeletal head in front of him, and gently touched the side of the skull with one hand.

"Sword Emperor senior, what did you find?" Shi Jiu immediately flew over, and then followed the other party's finger to look at the skeleton on the side.

The place where the Great Red Sword Emperor touched with his fingers was a gap, Shi Jiu didn't care, it was a normal gap at the top of the human skull, not a special place.

"This place has been tampered with, and you look carefully at this place with your sense, as well as the entire crest of the skull." Seeing that Shi Jiu still hadn't found anything, the Great Red Sword Emperor reminded.

"Okay, I'll check it out now."

With that, Shi Jiu unfolded his divine sense and carefully scanned the gap that the Great Red Sword Emperor had touched.

Soon Shi Jiu made a discovery, the gap touched by the Sword Emperor's predecessor had a trace of being moved, and the traces were very small, if it weren't for Shi Jiu repeatedly exploring this gap with his divine sense, it would be impossible to find it.

"Predecessor of the Sword Emperor, this place has been moved, and it seems that it has been opened." Shi Jiu said with some surprise.

"Well, it does. With all your might, you open the top of the skull along the gap. The Great Red Sword Emperor commanded.

Shi Jiu obeyed the command, holding the chin of the head with one hand, and the fingers of the other hand slightly bent against the top of the skull, and then exerted force.

"Click!" The top part of this skull was directly separated by Shi Jiu.

"Huh? There is a word on the inside of this skull? After breaking open the skull, Shi Jiu discovered the situation as soon as possible and immediately called out.

"Let me see."

The Great Red Sword Emperor leaned forward, and then levitated the skull handed over by Shi Jiu.

The words on the skull were known to Shi Jiu, so it was easy to read.

"My five door masters, by coincidence, I got this magnificent miracle - the Northern Soul Breathing Method, after a few years of practice, my skills are increasing day by day, just when I was betrayed by traitors, attracting terrifying opponents. Although I am a traitor, I am still invincible to the terrifying enemy, in order to prevent the Northern Hell's breathing method from being obtained by that person, I sacrificed the entire Five Doors General Altar, trapped it in the Gate Protection Array for a while, and I escaped into the Five Underground Hall. In order to relieve the hatred in his heart, he flayed the traitor alive and hung it in front of the hall to show his anger, and then in order to preserve the miracle of the world, he engraved it into the remains of the traitor. In the future, if someone is destined to get it, before the strength reaches the peak of the soul realm, do not show it, so as not to attract the disaster of killing, remember! ”

It turned out that this was the case, and Shi Jiu finally figured out some doubts in his heart.

"Little one, destroy this skeleton first, and when you get out of here, destroy this skull as soon as possible, and don't tell anyone about everything here." The Great Red Sword Emperor on the side said solemnly.

Shi Jiu nodded, what the Great Red Sword Emperor said was also what he wanted to do at the moment, everything about the Northern Immortal Breathing Method must not be leaked out, this skeleton must be destroyed, if it is seen by someone with a heart, maybe something will be speculated, the two dare not bet, so destroying this skeleton is the safest way.

Shi Jiu then took out a large sheepskin bag, then used his knife to chop off the entire skeleton that was hung by the four black irons, smashed it and put it into the sheepskin bag, and then flew to the fire pit behind him.

Shi Jiu did not hesitate, immediately opened the sheepskin bag and poured all the bone fragments inside into the deep pool, and after burning the sheepskin bag, he flew back to the previous hall.

"It's okay, now we can go back." Seeing that Shi Jiu had done all this, the Great Red Sword Emperor said lightly and disappeared.

The next moment, Shi Jiu flapped his flying wings and sped away in the direction he came.

The rest of the journey was smooth, and after passing through the square full of bones, Shi Jiu flew to the side of the dark river where he came.

After removing the flying wings, Shi Jiu changed into a diving suit, filled a sheepskin bag with air, and slowly walked into the dark river, then took a deep breath and dived into the water.

Ten minutes later, Shi Jiu surfaced.

"Finally outside." After taking a deep breath of fresh air, Shi Jiu swam to the shore.

Half an hour later, the diving suit was dried, and Shi Jiu threw it into the Sumeru space.

During this period, Shi Jiu used a dagger to erase all the handwriting on the inside of the skull, and then used a knife to cut it into several pieces and throw them in different directions.

Finally, Shi Jiu took out the fast horse that had been tied to the nearby before, and then galloped towards Yunshan Town.

By the time Shi Jiu rushed back to Yunshan Town, it was already dusk.

At this time, there were obviously more people in Yunshan Town than yesterday, and a considerable number of them were people from the sect or scattered cultivators, and they were either talking in groups of three or two, or they were looking forward to it alone, as if they were paying attention to something, or looking forward to something.

But Shi Jiu didn't notice all this, or he didn't care about the crowd around him at all, Shi Jiu was now bent on returning to the inn immediately, so that he could enter the Sumeru space to check today's super harvest.

After returning to the inn, Shi Jiu hurriedly went upstairs, then closed the door, and after a little arrangement, he couldn't wait to enter the Sumeru space.

At this time, the Great Red Sword Emperor was already waiting for Shi Jiu's arrival in the Sumeru space.

"Hehe, the little guy can't wait?"

Hearing the Great Red Sword Emperor qualifying about himself, Shi Jiu just smiled: "Senior Sword Emperor, the kid yearns for the legendary Magnificent Martial Arts, and wants to witness its true face as soon as possible. ”

"Okay, if you want to learn, just say it, don't hurry up."

As soon as the Great Red Sword Emperor finished speaking, Shi Jiu immediately ran over, and then stayed by the Sword Emperor's side, looking at the sixteen engraved ribs suspended in the air in front of him.

"I'll pass on to you the ancient characters I know first, and you can slowly understand them later." With that, the Great Red Sword Emperor pointed out, and suddenly a milky white light cluster appeared and instantly entered Shi Jiu's mind.

Shi Jiu immediately felt a little dizzy, and after a while, a lot of ancient dark characters appeared in his mind, but he still didn't know any of them, but soon, the corresponding fonts that he could recognize appeared under these ancient dark characters.

"Now I'll translate it for you, and then you can slowly understand it yourself." Next, the Great Red Sword Emperor told Shi Jiu the inscriptions on the sixteen ribs one by one.

Half an hour later, Shi Jiu memorized all the ancient characters on his ribs and the translated content.

"Next, you can understand it yourself, if you don't understand it, you can ask me, although I have seen it, there are still many places that I haven't been able to understand thoroughly, so you mainly have to rely on yourself." After finishing speaking, the Great Red Sword Emperor stopped making a sound and stayed quietly aside.

Seeing this, Shi Jiu also stopped talking, sat cross-legged in the Sumeru space, and then began to feel and understand these inscriptions.

During this period, Shi Jiu would ask the Great Red Sword Emperor on the side for help when he encountered something that he really couldn't understand, and the Great Red Sword Emperor also knew everything and said everything, even if they encountered something that neither of them understood, they would not be discouraged, and it would not be too late to dig deeper until the future.

At the same time as Shi Jiu's perception and understanding, he is also constantly using his perception in actual cultivation, tightening his abdomen, breathing qi and mobilizing the circulation of the underworld element in his body. Two hours later, between his breathing, the blood and qi in his lungs surged, and there seemed to be a surging sound, Shi Jiu knew that this was the first manifestation of cultivating the Northern Soul Breathing Method, and it could be regarded as just getting started.

"Okay, little guy, that's all for today's cultivation, practice tomorrow morning." The Great Red Sword Emperor stopped Shi Jiu's intention to continue.

"Hmm." Shi Jiu nodded, resuming his previous breathing.

As the saying goes, you can't be in a hurry in everything, and the same is true for cultivation, Shi Jiu also knows this truth very well, and now he has just stepped into the threshold of the Northern Darkness Breathing Method, as long as he persists, continues to perceive, understand, and apply it to practice, he will be able to achieve great success one day.

After suspending today's cultivation, Shi Jiu did not immediately withdraw from the Sumeru space, but walked to the side, at this time, the same word five underground halls, and today's other big harvest - the treasure small door is quietly suspended in the Sumeru space.

The Great Red Sword Emperor said that he could temper his willpower by looking at the mystical patterns on the Supreme Treasure.

"Little one, I don't feel like it's going to work, so I immediately turn my head and don't look at it again." At this time, the Great Red Sword Emperor on the side said.

"Hmm."

Shi Jiu walked to a place still a meter away from the Supreme Treasure Gate and stopped, and then stared at the vein where he had almost been hit earlier.

Ten seconds later, Shi Jiu immediately turned his head away and stopped looking at the vein.

"Yes, it lasted ten seconds, which is much better than you were before."

At this time, Shi Jiu felt a burst of surprise, he hadn't been able to hold on for even a second before he turned his head, although it was a performance without preparation, but now he could hold on for ten seconds, it was still a little incredible, because according to his own judgment, this time he could hold on for two or three seconds at most, the actual situation was very opposite, in one day, did he make such a big progress?

"Little one, are you surprised, why can you last so long?" The Great Red Sword Emperor asked with a smile.

"Well, I'm really surprised." Shi Jiu did not hide it and answered truthfully.

"This Northern Soul Breathing Method is really powerful, and it deserves to be ranked among the top three in the body refining method!" The Great Red Sword Emperor sighed.

"What? Can I hold on for ten seconds is the reason for this Northern Breathing Method? But I've only just touched the threshold, and to be honest, I'm not even getting started. Shi Jiu really couldn't believe it.

"Believe it or not, don't you count it in your own heart? It is not unreasonable that this Northern Darkness Breathing Method can make everyone covet, obviously in addition to refining the body, it also has other effects, which need to be discovered and explored by yourself. ”

The next moment, Shi Jiu sank down and carefully recalled everything that happened today, it was indeed because of the cultivation of the Northern Darkness Breathing Method that he had his current performance, and there was no other situation to explain.

"The Northern Breathing Method is really incredible!" At this moment, Shi Jiu had a more different view of the Northern Darkness Breathing Method, and at the same time, he was deeply shocked.
