Many times, when you hold something in your hand, you will inadvertently find something strange. But when you're really interested in something and want to find something special, you find it hard to find the clue no matter what.

And at this moment, Yi Yunfei happened to be in this strange circle and couldn't get out of it. The Daguan knife has been in his hands for more than three years, and he has always used him as an ordinary weapon.

Later, with the improvement of cultivation, when using this big knife, the infusion strength of Yuan Li also continued to increase, but the bearing capacity of this knife seemed to be endless, and there was never any problem. Many times, he was worried that because the Yuan Force was infused too violently, this ordinary long knife would shatter, but this knife surprised him again and again.

He had already vaguely felt that this knife was probably not as simple as he knew, but he didn't think about it deeply. Because with the improvement of his cultivation, Yi Yunzong's strength has gradually become stronger, and his knowledge has become more and more extensive, and he has seen the magic weapons that those powerful forces say to have, all of which contain various magical functions. He began to feel that this Daguan knife probably didn't have anything else special except for its toughness.

Until the appearance of the demon clan and the battle with him, when they saw the Daguan Dao, that kind of surprised expression was deeply imprinted in Yi Yunfei's mind. You must know that his knife was only obtained from a small sect in a remote area of Yizhou, Yi Yunfei can be very sure that the original backer sect definitely has nothing to do with the demon clan. And the demon clan has not set foot in the territory of the human race for tens of thousands of years, but all those who seem to know the origin of this knife are monks from the realm of the demon king of the demon clan.

The demon monk in the Demon King Realm is equivalent to the cultivation of the Terran King Realm, whether it is in the Terran territory or in the Demon Clan, he is no longer a small person. Being able to make such a monk lose his temper like this, the secret contained in this Daguan knife made Yi Yunfei have to pay attention to it.

There are two sides to everything, if this knife is just of an extraordinary origin, and the secret contained in it is good for Yi Yunfei, it is naturally the best. And what Yi Yunfei is most worried about is that the secret hidden in this knife will be unfavorable to him. After all, this knife seems to have an inseparable connection with the demon race, the demon race and the human race have not been in harmony since ancient times, and things related to them make Yi Yunfei have to be cautious.

Urging the Yuan Force to the maximum, and constantly pouring it, the Daguan Knife changed from pitch-black color to snow brightness, and the light became more and more abundant, illuminating the Nuoda Wentian Temple. It's just that the changes caused by the infusion of this Yuan Force are nothing more than that, and nothing special happens.

Yi Yunfei has been trying, he even used methods such as dripping blood to recognize the master, of course, he himself knows that this method is just the plot of the novel in his mind, and there is not much hope for it, and it is a matter of course that he failed in the end.

The overlap between the spirit and the body, as well as the mastery of the rules, is an important sign that the monk has entered the royal realm. You must know that the sensing ability of the divine soul is very extraordinary, no matter how keen the five senses of the monk's physical body are, it cannot be compared with the divine soul, and the overlap between the divine soul and the physical body is a leap forward for the improvement of the monk's combat power.

The first is the ability to perceive danger, the ability to sense the breath, compared to the monks under the king realm, it can be said that there is a world of difference, the monks who step into the king realm, whether they are in battle or not, the range around the body, even if there is the slightest fluctuation in the air, can be detected at the first time. And the most important thing is that for the use of the breath of heaven and earth, with the cooperation of the divine soul and the body without any delay, the spells that are cast are not only driven by their own yuan power, but mobilize the huge power between heaven and earth.

This was also one of the main reasons why the King Realm Cultivator was able to master the power of the rules. At the beginning, Yi Yunfei stepped into the realm of entering the gods and experienced the thunder tribulation of the Nine Rank Divine Souls, he originally thought that since the Nine Rank Divine Souls were the worst divine souls, their control over the power of heaven and earth would be much weaker than that of other monks. However, with the continuous improvement of his cultivation, he came into contact with more and more cultivators, and finally he was a little stunned to find that his so-called nine-rank divine soul was more condensed than other cultivators.

His Ninth Rank Divine Soul, in addition to absorbing the spiritual energy of heaven and earth when cultivating, the help of the divine soul will be much weaker than other cultivators, and the use of the power of heaven and earth is even more terrifying than others. He opened all the acupoint space in his body, opened the power of the bloodline, and for the absorption of spiritual energy, he did not rely on the help of the divine soul, and this disadvantage did not have any image at all for him. On the contrary, in terms of the use of the power of heaven and earth, it has taken a lot of advantage.

At this moment, Yi Yunfei was using the power of his divine soul to observe the Daguan Knife thoroughly from the inside out, without letting go of the slightest detail. But in the end, he didn't get what he wanted, and the spirit wandered around the Daguan knife, and what he saw was not much different from what he saw with the naked eye, as if this knife was really just an ordinary big knife.

It's just that he didn't realize that when his divine soul was about to penetrate the most core area of the Daguan Knife, there would always be a faint flash of light, and then his divine soul ignored something without him noticing.

"Could it be that this knife only had such a shocked expression after being recognized because it appeared in the hands of a famous master?" Yi Yunfei held the Daguan Knife and paced in the Heavenly Palace, his fingers tapping lightly on the Daguan Knife, and the doubts in his heart could not be answered.

"No, if it is a real master, the weapon used will definitely not be so simple, and there is definitely a secret hidden in it that I haven't discovered yet!" After pondering for a moment, Yi Yunfei suddenly stopped, shook his head very resolutely, and said in a cold voice.

The cultivation of the monk, his own cultivation is one thing, and the role of external objects is also huge, talismans, formations, magic weapons, any of them, can make the monk's combat power get a very terrifying increase. This Daguan knife can make the demon clan hundreds of millions of miles away remember it deeply, either it has very magical attributes, or it has appeared in the hands of a master who makes the demon clan attach great importance to it, no matter what the specific situation is, if it has no other role except for hard texture, no one can believe it.

"How can we crack the secret of this knife?" Yi Yunfei kept thinking in his heart, and at the same time did not stop exploring.

The eyebrow eye was activated to the maximum, and the scene in front of him changed suddenly, and the colorful world instantly changed into a monotonous world composed of black and white silk threads. The same is true of the Daguan knife in his hand, only this time, he finally saw something unusual.

The black and white lines are densely distributed, and there are vaguely different colors in the Daguan knife combined, which looks no different from other things under Tianyantong, but the color of those silk threads is much brighter than the colors of other silk threads, with a trace of silver light.

If it weren't for Yi Yunfei's eagerness to find the secret of the Daguan Dao at this moment, he would not be able to notice this subtle difference, because this difference is too subtle, and if he didn't observe carefully, he wouldn't have been able to find it at all. If he hadn't reached the cultivation of the king realm, he would not have been able to see through the lines of the rules, and he would not have been able to detect the difference at all, because there seemed to be some kind of mysterious power on this Daguan knife, which isolated the exploration of the divine soul.

At the moment when he noticed this difference, Yi Yunfei's spirit moved out at the same time, touching this slightly brighter thin line. This time, the power that isolated the divine soul failed to stop Yi Yunfei's exploration.

However, the invincible divine soul seems to have entered the quagmire at this moment, and the exploration on the Daguan knife is very difficult. And this situation made Yi Yunfei more and more sure that those bright silk threads absolutely hid the core secrets of Daguan Dao.

There were faint beads of sweat flowing out of his forehead, and the drive of the divine soul was also extremely laborious, but it was not easy to find a clue, Yi Yunfei would not give up, he gritted his teeth and insisted, and drove the divine soul with all his might, approaching the silver silk thread.

"Boom!" A voice like thunder sounded in his mind, and the divine soul finally touched the unusual place in the Daguan knife, but then Yi Yunfei felt a pinprick pain in his mind, and before he could react, the divine soul automatically retreated like a tide.

His body shook slightly, and his face turned pale. Yi Yunfei felt a breath blocked in his chest, and there was a burst of boredom in his chest and abdomen, and he crossed his knees for a long time to breathe before he eased his breath.

His exploration failed, and although he already knew the secret of this Daguan knife, he could see it but couldn't touch it, so he could only watch it in a hurry.

Yi Yunfei adjusted his mood, and there was not much change in his mood, he held the slightly cold Daguan knife in his hand, and walked back and forth in the room. Just now, when his divine soul touched the core of the Daguan Knife, a faint light flashed in his mind, and he seemed to have found a trace of spiritual light. However, it was interrupted by the sound of thunder, and this glimmer of spiritual light also flashed.

At this moment, he was carefully recalling the feeling of that moment, trying to find that glimmer of light. He was already eighty or ninety percent sure in his heart, if he could find that glimmer of aura, he would definitely be able to find the secret hidden in the Daguan knife today.

It's just that that glimmer of inspiration came too fast and went too fast, and this kind of recollection can't relive the feeling of Fang Cai at all. Yi Yunfei's brows furrowed slightly, and he looked at the Daguan knife in his hand with some trepidation, the feeling of the thunder just now, he still had palpitations, and he was very reluctant to try again.

But now it seems that there is no choice but this way.

He gritted his teeth, sat cross-legged on the ground again, and after about half an hour, he finally adjusted to the best condition, and then began to try again.

Because of the experience of one time, this time, Yi Yunfei is also familiar with the road, and the whole process is much smoother. With great effort, he approached the place in the Daguan Knife that was brighter than other regular straight lines, and the sound of explosion and thunder sounded in his mind again.

But this time, although his face was still pale and his body trembled, Yi Yunfei's face was overjoyed. Because he finally understood why that glimmer of light appeared.

The unique rule power contained in the Daguan knife gave Yi Yunfei a very familiar feeling at the beginning. It's just that the attack on the divine soul is too sudden, and the familiar power is not single, so he was blasted out before he could distinguish it.

And this time, when he was prepared, when he came into contact with that trace of the power of the rules, he immediately recognized this power, and it was indeed the power he was familiar with.

"What is contained in this is actually the power of the Thunder Tribulation, and there is also a very terrifying dragon power among them. Why does this knife contain such power? This Daguan knife has been in my hand for so long, and there is no sign of this power. If it weren't for my hard work, I wouldn't have been able to find out that there was something so terrifying in this seemingly ordinary broadsword. After the initial curiosity and exploration, Yi Yunfei fell into doubts again.

He felt the power of the Thunder Tribulation deeply, if he hadn't realized the method of using the Thunder Tribulation to refine his body in several Thunder Tribulations, he was afraid that he would have disappeared in the Thunder Tribulation a long time ago. And Long Wei, he felt it even more profoundly, because at least more than thirty percent of his divine souls were dragon souls.

It stands to reason that he has both kinds of power in his body, if this Daguan Dao is really as strange as Yi Yunfei imagined, when he has these two powers, he should also react.

Even if some kind of single power appeared on him, this Daguan Dao did not react at all. But when he has two powers at the same time, there must always be some kind of induction in this Daguan knife, right?

"It seems that we have to continue to give it a try!" Yi Yunfei thought for a moment, and simply didn't waste any more time, and directly used the trace of thunder tribulation power contained in his body to infiltrate towards the Daguan Knife.

After waiting for a while, I felt that the power of the Thunder Tribulation had completely infiltrated into the Daguan Knife, and the Daguan Knife was still silent, without any changes. Yi Yunfei was not discouraged, he mobilized the dragon power in his divine soul and pressed towards the Daguan knife.

The power of the Thunder Tribulation had not yet dissipated in the Daguan Knife, and the moment his power of Long Wei appeared this time, the dazzling golden light suddenly flashed on the originally pitch-black Daguan Knife, and the Daguan Knife, which was quietly placed, was strangely suspended.

Yi Yunfei cautiously looked at the Daguan Dao suspended in front of him, and the sound of a dragon's groan came from his ears. The Daguan Knife shrouded in golden light no longer has the lifeless appearance it used to be, as if it has been injected with some kind of spirituality, which is extraordinarily miraculous.

"Is this what you are?" Yi Yunfei hesitated for a moment, muttered in his mouth, and reached out to grab the Daguan knife.
