After descending about a hundred zhang, Lu Kun landed in front of a dark red boulder that was two zhang high, and strange blood qi fluctuations emanated from the boulder.

It is the Stone of Oath, which is a top-notch material in its own right, and when it is refined by a special method, it becomes the Stone of Oath.

And underneath the boulder, there are black mountain stones, with traces of artificial excavation, obviously this huge cave was excavated by the Blood Refining Sect.

Suddenly, the nerves in Lu Kun's body suddenly trembled, and his heart sank, such a feeling was obviously a monk far beyond his realm, scanning it with divine thoughts.

This cave where the Stone of Oath is placed is actually occupied by a Yuan Infant Monk!

Master Rong didn't seem to notice it, he said proudly: "This is the oath stone of this sect, it has continued from the opening of the Blood Refining Sect to the present, and after the blessing of the great elders of this sect, it can now form three bloodline oaths. ”

"Even if you advance to the Avatar Stage cultivator, you can't disobey it. ”

"I'll teach you a simple spell, and you can do it. ”

Lu Kun said respectfully: "Yes, Master Rong." ”

Just as Master Rong was about to teach Lu Kun the formula, a red dot suddenly lit up on the stone of the oath, and the word "Ma Fei" vaguely appeared on it.

"Hmph, break the sect's oath and die!" A fierce and sharp female voice suddenly resounded in this cave, and then a black spiritual light shot out from the ground and hit the oath stone, causing the red dots of the word "Ma Fei" to shatter directly, turning into a gray smoke and dissipating in the air.

Seeing this, Master Rong hurriedly bowed to the void and said, "I've seen Uncle Le!"

This female voice then resounded in the cave**: "Senior nephew Rong, after you deal with this little guy, arrange for someone to investigate this 'Ma Fei', see what losses this sect has, and then come back to report to me." ”

Rong Shizu said in a deep voice: "Obey." ”

Then this Yuan Infant Divine Thought fell silent, ignoring Lu Kun, who only had the Great Perfection of Qi Refining next to him from beginning to end.

Lu Kun felt a little frightened, he had just come to the Blood Refining Sect, not to mention the many Divine Senses of the Formation Stage, and he also met the Yuan Infant Stage cultivators, the Blood Refining Sect was really unfathomable, and there were many high-level cultivators.

"Okay, Zhang Yiyang, quickly cast the spell according to my mantra. ”

Next, Patriarch Rong dictated a simple spell and an oath that Lu Kun needed to recite.

This spell is extremely simple, even a disciple in the middle stage of Qi refining can cast it.

Lu Kun first blessed himself with a giant force technique, slapped a fist in his chest, and spat out a mouthful of blood from his mouth, and the blood was condensed in front of him with a physical control technique.

The blood essence of his body has been condensed into the inside of his bones, and the blood flowing in his veins has no vigorous qi and blood, and the blood that he has forced out now is only a little more vigorous than ordinary immortal cultivators.

Rong Shizu obviously didn't notice the abnormality of Lu Kun's blood, his face was a little serious, obviously still thinking about the "Ma Fei" just now.

"This oath spell should use the oath stone as a medium to gather everyone's blood to form a bloodline oath to achieve the oath prohibition effect of the immortal cultivation family. ”

Lu Kun thought back to the scene just now, and a trace of clarity flashed in his heart.

This kind of prohibition does not seem to be immediate, but first feedback to the Oath Stone, and then the monk sitting here needs to cast a spell to activate the power of the prohibition and kill that person.

The time gap between the onset of the ban is the time when Lu Kun uses his divine sense to conceal the divine power to dodge, or when he violates the oath, he uses the divine power, so that the power of the prohibition cannot be transmitted to the oath stone.

"It's a pity that I have this Dan stage monk by my side, otherwise I don't know if my oath will succeed after hiding all my divine sense. ”

After Lu Kun entered the Qi Kingdom, he had already hidden most of his Divine Soul Divine Sense, and only revealed that the level of the Great Perfection of Qi Refining was outside the Sea of Knowledge, so that he could hide from the high-level cultivators of the Blood Refining Sect.

Thinking like this in his heart, Lu Kun's hand was not slow, and he pinched the law decision, and recited words in his mouth.

"I, Zhang Yiyang, have officially joined the Blood Refining Sect!"

"Make three oaths, one: never betray the Blood Refining Sect, two: never spread the Blood Refining Sect exercises, and three: never destroy the same sect, violate any of them, and the divine soul will dissipate!"

As he completed his spell casting, the blood of the Oath Stone in front of him rose, and then Lu Kun's blood was absorbed into it, turning into a blood spot, and the three words Zhang Yiyang loomed in it.

Then, Lu Kun felt an inexplicable prohibition that appeared on his divine consciousness outside of the sea of consciousness, and the power of the prohibition made Lu Kun's pupils shrink slightly.

He felt that the power of this prohibition was countless times stronger than the ordinary Divine Soul Oath, but this divine power of his Hidden Spirit Root was really weird, and this prohibition seemed to only affect a small part of his divine sense, and he didn't find other parts of the depths of his consciousness sea.

This feeling made Lu Kun breathe a sigh of relief, so it seemed that even if this Oath Stone exerted the power of prohibition, it would not have much impact on his divine consciousness at the peak of the middle stage of the Jie Dan.

Rong Shizu next to him saw that Lu Kun had completed the spell, and a purple-black token suddenly appeared in his hand, levitating it in front of the Oath Stone, and then chanting some words, pinching the complex magic decision in his hand.

Lu Kun vaguely heard Zhang Yiyang's three words, and soon, a trace of red dots floated out of this oath stone and disappeared into this token.

Rong Shizu moved the token in front of Lu Kun and said, "Zhang Yiyang, this is your Blood Refining Sect token, only you can refine it, it contains the basic information of the Blood Refining Sect, you can go back and study it yourself." ”

Seeing Lu Kun put away the token, Master Rong's body was full of inspiration, and he flew into the sky with Lu Kun and left this Oath Stone Cave.

After going up, Rong Shizu sent Lu Kun out.

Lu Kun left the secret room, slightly stunned.

I don't know when, several foundation building period monks appeared outside the secret room, all with solemn expressions.

"Come in, a few of you. ”

"Yes, Master!"

It turned out that these disciples in the foundation building period were the disciples of Master Rong, and they were called over by Master Rong somehow.

Lu Kun was vaguely aware of what these people were going to do, one of them should be to investigate the disciple named "Ma Fei", and the other task was likely to investigate his details.

After all, a Lei Linggen cultivator who has cultivated to the Great Perfection of Qi Refining is a little strange to get started, with such qualifications, as soon as he cultivates immortals, he will be abducted.

Although Lu Kun made a sect oath, just in case, Master Rong must find out.

Lu Kun was quite confident in the origin of what he said before, the so-called Zhang family in Beihuangzhou was solved by Huang Xiaoyun and Pan Yan, and the descendants were also secretly destroyed by Huang Xiaoyun.

Lu Kun pretended to be the son of this descendant disciple.

As for whether there are still any remaining disciples in the Zhang family, after so many years, it is difficult to investigate, after all, this is a very small family, even if the Blood Refining Sect finds out, Lu Kun will be able to say the name of this descendant disciple and take out some evidence.

These thoughts flashed through him, and Lu Kun took the token in his hand and walked out while injecting mana to refine it.

"This Senior Brother Zhang, please stay. ”

Lu Kun didn't take a few steps before he heard a rather flattering voice, he turned around and saw that it was the middle-aged man who was guarding the gate before and looked very obscene.

Lu Kun glared at him with his eyes, and said fiercely: "What's the matter!"

When the middle-aged man saw Lu Kun's hideous face, his body trembled in vain, he swallowed a mouthful of spit, and said with a dry smile: "Senior Brother Zhang, don't be angry, Senior Brother just wants to introduce the sect to Senior Brother." ”

Lu Kun's eyes narrowed, and he said with a hint of chill in his words: "What, you want to earn spirit stones from me!"

The middle-aged man was excited, and hurriedly said: "How dare you accept the spirit stone of the senior brother, this is what the junior brother should do, what he should do." ”
