Sitting cross-legged on the bed in the inner room, Du Fei didn't make any moves, but squinted slightly at the quaint wooden box in front of him, thinking a lot in his heart.

The wooden box is made of agarwood, although it is old, but there is no damage, and where it is opened, the beeswax that seals the opening is also a piece of black, obviously, this thing has not been opened for many years.

"Is there really a secret of King Dan's ruins in this?

Compared with being in front of Yun Yuqing just now, Du Fei became more and more calm at this moment, but it was this calmness that made him even more puzzled in his heart.

After all, when it comes to the legendary Heaven and Earth Yuan Dan, anyone will be crazy, and Du Fei doesn't believe that Yun Yuqing will be like what she said, and she has no interest in the Heaven and Earth Yuan Dan.

So considering all kinds of situations, Du Fei thought of two possibilities. First, it is the so-called Danwang ruins, it is very likely that there is no Heaven and Earth Yuan Dan at all, if Yun Yuqing is not interested in the alchemy classics inside, it is very easy to understand. The second is that there is indeed the existence of Heaven and Earth New Year's Day in the Danwang Ruins, and to get that thing, you need a Dan Master...... However, the Dan Master, who is too strong, is not well controlled by Yun Yuqing......

And people like herself are easier to control, and even, because of the relationship between the two of them who are "weak-hearted", even if she kills people afterwards, I'm afraid no outsiders will know!

If this is the case, then it is likely that the woman has some kind of hole card so that she will not be afraid of the eight-rank martial artist...... However, she may not have succeeded in this kind of hole card at the moment, and it should take half a year for the hole card to really work, otherwise, the two of them will now go to find the ruins of King Dan, and they don't need to wait until half a year later......

"Sure enough, it's the most poisonous woman's heart!" Du Fei sneered slightly, and then muttered.

But no matter what, since there are clues to the Danwang ruins, I will definitely not give up, and it will take half a year...... There are also a lot of things you can do!

After sorting out the key points in the matter, Du Fei breathed a sigh of relief. In any case, half a year is extremely important for Yun Yuqing, but for herself, this half a year is the same.

If you only have this strength, then even if you go to the Danwang Ruins, I'm afraid that you will be swallowed by that woman in one bite.

............

After taking a breath slowly, Du Fei's palm pressed on the wooden box in front of him, and after a while, the true breath in his body shook slightly, and the beeswax in the sealing place of the wooden box had been shaken open by the true breath, and what appeared in front of Du Fei was quite a bit dark at the bottom of the box.

The smell of time seemed to come from inside the box, and after a while, the dark feeling slowly disappeared, but Du Fei finally saw the contents of the box clearly.

"Ring ......"

Frowning slightly, Du Fei slowly took out the ring and put it in front of him.

The shape of the ring is simple, like a dragon, end to end, and slightly twisted, but in addition to the simplicity, people do not see anything strange.

However, it is this "ordinary" that makes this ring more and more extraordinary.

The reason is simple, that is, with such careful preservation, it is impossible to keep just an ordinary ring.

After thinking for a moment, Du Fei still couldn't figure out where to get through, but he didn't want to waste his kung fu in this place, so he just gave an order quickly in his heart.

"Xiaobai, is there a way to test this ring. ”

"Beep-"

"Command received, inspection program started, inspection in progress - results already available, do you want to read them?"

"Read it so fast!"

"Detected as some kind of spatial container, there is probably a few zhang of storage space inside, if it needs to be opened, it needs to leave a soul imprint on it - is it open?"

"Is this thing a ring of Rong?" The corners of Du Fei's mouth twitched slightly, and his face also showed a bit of disbelief, but he would not have any opinion on such a result. After all, items such as Rong Ring have always been rare to see, even in the Du family, no one has this thing, and it is a surprise that he can get this thing.

"Help me open it!" After a while, Du Fei quickly ordered.

"The order is received, the original soul imprint has been erased, leaving a soul imprint, and the master can use this thing at will!"

With the cold electronic sound in his mind, Du Fei suddenly had a rather mysterious feeling, that is, he seemed to be able to vaguely perceive what the space in this ring was.

After hesitating for a moment, Du Fei subconsciously put the ring on his left hand, and reached out to wipe it slightly, and suddenly, a small medicine bottle appeared in front of him.

"It's... Pill!" Du Fei was slightly happy, and after a while, he didn't hesitate to reach out and wipe it on Rong Ring again, but this time, a rather old and broken scroll appeared in his hand.

But apart from these two things, there was no one else in the Rong Ring. But even so, it was a bonus.

After hesitating for a moment, Du Fei reached out to open the medicine bottle, and suddenly, there was a strong medicinal fragrance rushing to his face, although he only smelled it, but Du Fei was instantly shocked.

"It's... Cleansing pill... No, although the medicinal effect is similar, judging by the medicinal power contained in it, this should be something more advanced...... Is it the Eight Rank Pill?" he sniffed the medicine lightly, slowly poured out a pill from the medicine bottle, and after carefully examining it for a while, Du Fei hesitated.

"This is indeed not the Nine Pins Pill Pill Cleansing Pill, but the Eight Pins Pill Condensing Pill, its effect is similar to that of the Cleansing Pill, but the effect is very different. When Du Fei was in a daze, Xiao Bai's cold voice sounded faintly.

Du Fei was slightly stunned for a moment about the unreliable system that took the initiative to speak for the first time, but he didn't know a little bit about this system, and he didn't know how to react at the moment, but after hesitating for a moment, he said lightly in his mind: "Xiaobai, how do you know that this thing is an eight-grade pill." ”

"It is recorded in the system information, no matter the shape, taste, or medicinal power, there is no mistake in the slightest, the owner just needs to take it with confidence!" Xiao Bai's cold voice sounded again.

"How do you know this?"

"Beep-the master doesn't have enough authority to answer-"

"Uh-it's permission--" sighed helplessly, and after a while, Du Fei put this question behind him, and instead quickly poured out all the contents of the medicine bottle with an expression of picking up the money.

"One, two, three...... There are nine of them, and it seems that I have grown big this time!"

With these nine pills, even if he swallows hard, he can swallow a nine-rank martial artist, and at that time, with the true qi, combined with the pill he knows, it seems that refining a large number of marrow cleansing pills is not too much of a problem.

"Okay, let's see what the other thing is!" clapped his hands slightly, and then, Du Fei slowly spread out the ancient scroll in front of him.

Where I saw it, there was a chaotic line, which made people dizzy for a while, but after looking at it for a while, Du Fei understood that what these dense lines indicated should be where the Danwang ruins are located.

And I can't understand it at the moment, it's probably because the map is only half related, unless you can get the other half in your hands, otherwise, no one can know where the Danwang ruins are.

If you let the system enter this thing and then destroy it yourself, then wouldn't it mean that no one will have a way to find the ruins of King Dan except yourself!

And even if it is Yun Yuqing, in this case, I am afraid that there is no way to make any unfavorable actions against himself.

As soon as he thought of this, Du Fei did what he said, and at that moment he quickly gave an order, let the system enter the data, and then closed his eyes and dived into the consciousness space, after careful comparison, and found that there was nothing wrong, Du Fei was relieved and boldly destroyed the worn-out scroll.

Squinting at the slowly burning ancient scroll in front of him, Du Fei didn't feel anything else. No matter how precious this scroll is, but destroying it in this way, the benefits of bringing it to yourself are definitely innumerable! No matter what other thoughts Yun Yuqing has, if she destroys this thing now, she will definitely not miss it at all!

Looking at the burning ancient scroll for a moment, Du Fei was about to leave, but he suddenly frowned slightly, only to see that most of the scroll had been turned into ashes under the burning fire, but there was a palm-sized piece among them, not only did not have anything to do under the incineration, but with the incineration, all the lines on it had disappeared, and instead of a kind of simple handwriting with a faint luster, appeared on it......

"It's ....."

Du Fei didn't know what he felt about this change, but after hesitating for a moment, he quickly extinguished the flames, and then grabbed the golden fragment that was still a little hot in his hand, and slowly looked at it following the handwriting......

"Dan's technique, Dan's rebellion!"

As soon as the seven words appeared, Du Fei's face changed slightly, and after a while, he couldn't help but look up and laugh!

Dan technique, unlike martial arts, is a skill that only Dan masters can cultivate. And the difference between this skill and martial arts is that the energy that activates the skill is not true breath, but an elixir!

As we all know, the elixir contains extremely powerful energy, and the Dan technique is to trigger the energy in the elixir to form an offensive technique similar to martial arts!

However, in addition to the level of the Dan technique, what is more important is the pill as an introduction! If there is a high-grade pill as an introduction, then even if it is the most ordinary Dan technique, the power it exerts is probably unimaginable to ordinary people!

And the Dan technique is also one of the reasons why the status of the Dan Master is so prominent on the Xuanwu Continent!

As long as there is an elixir, it will be powerful, if there are endless elixirs at hand, then how many people can be its opponent!?
