Yin Zhishan and the five of them have been wandering around the Ten Thousand Demon Cave, and no one has ventured into the legendary Ten Thousand Demon Cave.

In the void, Yang Kai quietly observed the Ten Thousand Demon Cave that stretched for an unknown distance, the surging demonic qi made the soul tremble, fortunately, Yang Kai's sea of knowledge had the red golden brilliance that fell from the Heavenly Seal and the Dao pattern emitted by the Nine Ancient Characters, he did not feel frightened, but he did not dare to venture into the Ten Thousand Demon Cave.

However, Yin Zhishan's five people are far away, although there are treasures to protect their bodies, it is difficult to approach the Ten Thousand Demon Caves, they are all wandering, waiting for the opportunity.

Dragon Soul Knife, a legendary magic knife, is the treasure of the demon clan, since Yin Zhishan's five mouths, Yang Kai learned that this knife has been missing for tens of thousands of years, and the demon clan has been trying their best to find this legendary magic knife, but there has been no news.

A few days ago, the demon monk named Wuchuan heard the sound of a dragon's chant in the Ten Thousand Demon Cave and vibrated out, and saw a sword light penetrating the heavens and the earth, which was very similar to the legendary Dragon Soul Knife, and there was not much difference from the ancient secret book recorded in the demon race.

Yin Zhishan and the thin young man are naturally the leaders of the five, from their conversation, it can be analyzed that Yin Zhishan and Shocking Heaven have been secretly competing in the demon clan for some time, this time, Yin Zhishan is determined to win the Dragon Soul Knife, as long as he gets the legendary Dragon Soul Knife, Shocking Heaven is naturally not his opponent.

Yang Kai was hidden in the void, quietly looking at the five people below, he knew that these people lived in intrigue on weekdays, although they were determined to win the Dragon Soul Sword, but no one was reckless, the danger of the Ten Thousand Demon Cave was not groundless, they were waiting for the right time to make a move.

These people want to target the earth-shattering, Yang Kai naturally won't let them succeed, although the earth-shattering is the young master of the demon clan, but he and Yang are happy, they can be described as a friendship, even if they see each other as their own brothers, it is not an exaggeration.

"Boy, you can try the Heaven Devouring Demon Skill!" While Yang Kai was arguing with the brown-haired dog, the mysterious being in the Ring of Annihilation suggested Yang Kai with his mind.

Yang Kai was slightly stunned, in the presence of the Heaven Swallowing Beast, this mysterious existence with an incomprehensible relationship with himself actually chose to spread the word at this time, it can be seen that he is not very afraid of the Heaven Swallowing Beast, Yang Kai's mind moved slightly: "The Heaven Swallowing Demon Skill is powerful, but it is not the most complete Heaven Swallowing Demon Skill, in a dangerous place like the Ten Thousand Demon Caves, it is difficult for the Heaven Swallowing Demon Skill to play a substantial role." ”

Taking this opportunity, Yang Kai wanted to confirm the speculation in his heart, he had long doubted the integrity of the Heaven Swallowing Demon Skill, at least one thing, Yang Kai was very sure that the mysterious existence did not teach him the forbidden technique of the Heaven Swallowing Demon Skill, as for the other aspects of the Heaven Swallowing Demon Skill, there was more or less a little bit of it that had not been passed down, and the mysterious existence retained some key points.

At this time, the mysterious existence asked him to try the Heaven Devouring Demon Skill, and Yang Kai would naturally test it.

For a long time, there was no response from the mysterious being, everything seemed to be silent, and it seemed to be contemplating for a long time, which was a long wait.

Yang Kai sometimes felt that the mysterious being was contemplating, sometimes he felt that the mysterious being was planning something, and sometimes he felt that a breath of death was threatening him—this was an ordeal, it seemed like it was only for a moment, but it seemed like it had been experienced for a long time.

After about a quarter of an hour, the mysterious being's words were full of confusion and shock: "You've already guessed it?"

Hearing this, Yang Kai's heart trembled suddenly, his guess was confirmed, otherwise the mysterious existence would not have asked like this, although everything was in his expectations, however, Yang Kai still felt the tremor of his soul, all along, he had been practicing by his side with a calamity, if it weren't for the encounter with the Sky Devouring Beast, Yang Kai felt that the moment he asked this sentence, the mysterious existence in the Ring of Silence would have taken his life, and the breath of death just now was the revelation of the mysterious existence's murderous intent.

Yang Kai tried his best to remain calm, nodded slightly, and said softly: "That's right, I guessed it a long time ago, I don't know what you want from me, or what you want to use me for, but you helped me before, and I, Yang Kai, still have to thank you." ”

Having said that, it was difficult for Yang Xingxin to calm down, such a scourge was around him, since the moment he got the Ring of Annihilation, there was such an unknown existence in the Ring of Annihilation, at that time, the other party's strength was still very weak, not strong, but with the progress of his cultivation over the years, the cultivation of the mysterious existence in the Ring of Annihilation was still improving, and his strength was still improving, and his progress was very fast, faintly, Yang Kai felt that this existence was on par with the Heaven Devouring Beast.

"Hey-" A long sigh swirled in Yang Kai's sea of knowledge, and the voice seemed extremely vicissitudes, the same as the voice and tone that Yang Kai heard for the first time: "I really didn't teach you the full version of the Heaven Swallowing Demon Skill, the Dao Sutra you cultivated is your main **, if the Heaven Swallowing Demon Skill is also completely taught to you, the two equally domineering secret texts will make you irreversible." ”

"Really?" Yang Kai naturally wouldn't believe in the words of mysterious existence, firstly, the Dao Sutra he cultivated was mainly based on the Dao Heart Secret Collection, and secondly, the Heaven Devouring Demon Skill was to cultivate the Purple Mansion World, there was a conflict between the two, but Yang Kai could completely resolve this conflict, because the path of cultivation he took was completely different from that of others.

In the past, he was worried that cultivating two equally advanced ** would hinder him, but since the Dao Heart Secret Vault and the Purple Mansion World were isolated, cultivating two ** at the same time, through the transformation of the Gate of Life, the two could coexist, so Yang Kai was not afraid to cultivate the Dao Sutra and the Heaven Devouring Demon Skill at the same time.

Now, the reason given by the mysterious existence for such an explanation is obviously untenable.

"Whether you believe it or not!" The voice of the mysterious existence is still vicissitudes, and said: "Although the Dao Sutra you have cultivated is powerful, it is not a scripture created by the Great Emperor after all, compared with the real Heaven Swallowing Demon Skill, there are still some shortcomings, if you don't talk about some of the scriptures in the Heaven Swallowing Demon Skill, the path you cultivate is also destined to be the same as others, taking the road of the Purple Mansion World." ”

The mysterious existence seems to be a person who has gone through eternity, a person who is physically and mentally exhausted, and a person who seems to have taken care of the red dust, and his voice seems to contain a lot of emotions and stories, and this explanation seems to be extremely reasonable.

Slightly reminded by the mysterious existence, Yang Kai was also thinking about such a question: The Dao Sutra is indeed a cultivation of another way**, as the mysterious existence said, it is not a scripture created by the Great Emperor, compared with the real Great Emperor's scriptures, there are still many deficiencies, although it is said that the ancestor of the Yang family who created the scriptures has the strength to compete with the Great Emperor, but after all, he did not become the Great Emperor, so the Dao Sutra is deficient, even if he finds the lower half of the Dao Sutra, Yang Kai still needs time to carefully study and repair some key points, so that the Dao Sutra becomes a real Great Emperor**.

"But—" the mysterious being continued, "I have no ill will towards you, and I think you've been on guard against me, but I don't have any ill will toward you—"

Yang Kai was slightly stunned and said: "In this case, why don't you show your true face, why don't you explain everything, if you don't have any purpose in me, I don't think you will stay in the Silent Space forever." Yang Kai said loudly, since the two sides have already made it clear, they might as well throw out all the doubts, it is naturally good to have an answer, and there is no rush if there is no answer, anyway, Yang Kai is ready for the two sides to fight.

After the mysterious existence was silent for a moment, the voice of the vicissitudes of life resounded again, and said: "If the purpose is to say, I just want to rely on your life energy to nourish myself, but I have never taken anything from you, I just rely on the life energy you usually exude for my own use, otherwise, do you really think that you can live under my gaze and surveillance?"

The energy of life, just relying on the energy of life that he exudes, can nourish his body, so how powerful is this person, Yang Xingxing is full of many doubts, if this is the case, what kind of situation is this mysterious existence so powerful.

Yang Kai asked again, "The first piece of Nine Heavens Xuanyu is more than ten thousand forbidden, right?"

"Huh?" The mysterious existence in the Silent Destruction Space was visibly condensed, and he said in shock, "Have you realized other methods on the Xuanyu?" This was just his tentative inquiry.

Yang Kai shook his head slightly, and said, "No, it's just by feeling, on the first piece of Nine Heavens Xuanyu, there must be more than just a ban on Wanhua." ”

"That's good!" the mysterious being affirmed: "The ** recorded on the Nine Heavens Xuanyu is not suitable for you!"

The explanation of the mysterious existence is unusually simple, just one sentence, which does not seem to be an explanation, but a tough attitude.

"Not suitable for me?" Yang Kai sneered: "How do you know that the ** on the Xuanyu is not suitable for me? You may have good intentions, but I can't understand it, so, no matter what kind of ** is on the Xuanyu, after the trip to the Ten Thousand Demon Caves, I, Yang Kai, will also go to study it, even if I don't cultivate, it will be extremely beneficial to my immortal path to understand something." ”

Silence, silence!

After the tea cup kung fu, the mysterious being said again: "I advise you not to study the ** on the Xuanyu, that ** is completely in conflict with the Dao Sutra you are cultivating now." ”

The voice of the mysterious existence was very solemn, and it seemed that he really didn't want anything to happen to Yang Kai.

Yang Kai was slightly stunned, and then asked, "Is it directly related to the force where Ji Changkong is located?"

The mysterious existence did not answer directly, but told Yang Kai a secret: "In the era of the existence of the Qing Emperor, the Yang family was born with the strongest man, on the road of immortals, and the Qing Emperor has been competing, the ** of the two people is diametrically opposed, the Yang family takes the road of the secret of the Tao, while the Qing Emperor is taking another unknown road, until now no one knows, what kind of road the ** cultivated by the Qing Emperor, but as long as five of the Nine Heavens Xuanyu are collected, this secret will surface; Destined to clash with each other, they fought all the way, and in the end, the Qing Emperor defeated the Yang family's amazing people with an advantage of one move, so far, the Qing Emperor entered the realm of the Great Emperor, but his unique ** has not been handed down, leaving to future generations is still the road of the Purple Mansion World, and his own ** is imprinted on the nine pieces of Xuanyu, only when you get the Xuanyu, this ** can reappear in the world, and the Dao Sutra you are cultivating is precisely with this **. ”
