At the border of the northern land, the steward's convoy had once again moved slowly.

It's just that this time in the center of the butler's convoy, there is an extra carriage, and the butlers have protected the carriage very tightly at the moment, which seems to be extremely important.

Guan Yan, who was at the front of the team, glanced back at the carriage, but a complicated look flashed in her eyes, the scene before that day, even she was a little apprehensive, let alone the other housekeepers. At this moment, let alone provoking the one in the carriage, even if you say a word to him, it is estimated that many of the housekeepers will have to tremble!

Who would have thought that a half-dead guy picked up on the side of the road would be such a strong man?

It is precisely because of this that at this moment, Guan Yan has listed Du Fei as the key person of this trip, if it is not a critical moment, Guan Yan does not want Du Fei to show up, in this way, Du Fei can be turned into a hidden killer, which is an absolute good thing for the housekeeper.

At this moment, in the spacious carriage, Du Fei sat quietly cross-legged, and with his breathing, the true qi in his body was instantly adjusted to the smoothest point by him.

Five-grade peak martial arts realm!

After experiencing an impact and surviving the Sect Breaking Tribulation, Du Fei finally officially entered the Five-Rank Peak Martial Sect Realm.

It's just that there aren't too many surprises in Du Fei's heart at this moment, because the Yanzong Pill that can be used for his own cultivation has already been used by Du Fei in order to rush to the level, so if he can't find a new cultivation source at this moment, then Du Fei's strength is likely to stop like this!

However, this is not the result that Du Fei wants.

"Guan Ting, can I ask you something?" Du Fei slowly opened his eyes, looked at Guan Ting, who was also in the carriage with a sick face, and said softly.

"Oh, Brother Du Fei, what's the matter?" Guan Ting saw that Du Fei had woken up from his cultivation, and Guan Ting said quickly. After seeing Du Fei's impact on the sect tribulation, Guan Ting took a little less care of Du Fei, but she admired it a little more.

Du Fei was silent for a moment before he flipped through it, took out a demon crystal that he had caught before, handed it to Guan Ting, and said softly: "Little girl, do you have a way to refine it?"

"Hmph, you underestimate me!" Guan Ting snorted, and then saw her put this demon crystal on the palm of her hand, and with the urging of true qi, she suddenly saw that there were wisps of pure energy overflowing from these demon crystals in an instant, and then accompanied by Guan Ting's movements, she was sucked into her body.

"This, how did you do it?" Looking at this scene, Du Fei frowned slightly, although he watched this little girl do this once, but he couldn't see how she refined this demon crystal.

Hearing Du Fei's words, a hint of thoughtfulness flashed in Guan Ting's eyes, and after a while, she leaned over mysteriously and said in a low voice: "Brother Du Fei, if I guessed correctly, you shouldn't be the person from our Sealed Realm, right?"

"How did you guess?" Du Fei's eyes flashed slightly, and then he sighed and did not deny it.

"Because of the people of our sealed realm, who doesn't know this method of refining demon crystals!" Guan Ting smiled and said, "But Brother Du Fei, don't worry, I won't tell your secret, because you are a good person." ”

"Good people. Hearing this, Du Fei couldn't help but reach out and touch his nose, sighed, and then said softly, "Little girl, can you teach me this method?"

Hearing this, Guan Ting nodded, and then said softly: "Actually, this is not a complicated method, you only need to use your true qi as a guide to seal out the energy in the demon crystal and refine it." ”

As she spoke, Guan Ting took out another demon crystal and explained in detail the method of refining the demon crystal.

After hearing Guan Ting's words, Du Fei was a little surprised, this method of refining demon crystals is similar to refining the elixir by himself, but the energy of the elixir is pure, and what he needs to do is to refine it directly, but the energy in the demon crystal is a little complicated, and he can only carefully put forward the energy in it according to his own needs!

Because, the nature of the true qi of each person's cultivation is different, so there are also trade-offs between the types of demon crystals that can be refined, to put it simply, refining the demon crystals that match the true qi attributes of your own cultivation! As for the demon crystals that do not match your own true qi attributes, even if you want to refine them, it is estimated that you will not be able to refine them!

After thinking carefully about this method of refining demon crystals in his heart for a while, Du Fei turned over his hand and randomly took out a few demon crystals that he "picked up" that day, and then according to Guan Ting's words, he probed his true qi into the demon crystals and tried to see which demon crystal was most suitable for him.

"Whew-"

With Du Fei's movements, the energy in the first demon crystal was drawn out by it slightly, and then with the operation of the true qi in Du Fei's body, the energy emitted from this demon crystal was slowly refined by Du Fei.

"It's kind of interesting. After refining a demon crystal, Du Fei couldn't help but nodded, the energy contained in this demon crystal was extremely rich, much richer than Yanzong Dan, and perhaps because the attributes of this demon crystal just fit the relationship between his true qi attributes, Du Fei felt that the energy in this demon crystal seemed to have been refined by himself.

"Brother Du Fei is so powerful, I have rarely seen someone who can do this when he refines the demon crystal for the first time. Guan Ting also looked at this scene with a surprised face, and her little face was full of consternation.

"Brother Du Fei, let's try other types of demon crystals, maybe you can refine two or three types of demon crystals!" Guan Ting was surprised for a moment, and then put forward another opinion.

Hearing this, Du Fei nodded slightly, and then picked up another demon crystal and refined it.

"You can actually refine them all?"

This scene made Du Fei and Guan Ting both look at each other a little, and at that moment, Du Fei quickly picked up a few demon crystals and quickly refined them.

Accompanied by Du Fei's movements, Du Fei was a little shocked to find that it seemed that no matter what kind of demon crystal was in front of him, it could be refined without any hindrance.

"How can this be?" Guan Ting's little face was full of surprise, obviously Du Fei was able to do this kind of thing, which made her extremely surprised.

"This, maybe it's because of the relationship between people outside my sealed realm, right?" After thinking for a while, Du Fei guessed that this might be because of the relationship between the Rongtian Pill in his body, but this kind of thing involving his own secrets, Du Fei naturally couldn't say it directly.

Fortunately, Guan Ting didn't mean to pursue it, but nodded and said: "It should be this reason, I also heard that you people outside the realm can cultivate to the Martial Saint Realm, maybe that's the reason." ”

"Okay," Du Fei stretched his waist, now that he figured out his next cultivation method, Du Fei relaxed a little, and then he glanced at Guan Ting and said with a smile: "I think your sister Guan Yan should have explained a lot of things to you, right?" ”

"Do you know La?" Guan Ting stuck out her tongue, and then said softly: "Sister Guan Yan wants me to tell you that the place we are going to next is called the Necromantic Abyss, which is the destination of our trip, and the ancient Heavenly Phoenix of the Nirvana period is inside, so the next road can be said to be full of dangers!"

"Necromantic Abyss?" Hearing this, Du Fei nodded, but didn't say anything.

"Well, moreover, the most troublesome thing is not the Necromantic Abyss, Sister Guan Yan said, if she didn't guess wrong, it should be the Zhou family, one of the four major families in the Northland, who shot at us before. Because, Zhou Cheng is one of the closest forces to our Guancheng, because of various relationships, the relationship between our two families has always been extremely poor, and many clansmen have died in each other's hands in the struggle for many years. ”

"And this time, after we got the news of the ancient Tianfeng in the Necromantic Abyss, we have already sent our team of people out first, even if the other forces know about this, if they want to keep up with us, it should be too late in time, so it is most likely that only the people of Zhou City, and only the people of Zhou City, have so much resentment against us. ”

"And the person who shot behind the back that day is likely to be the Dan Master that Zhou Cheng invited back from somewhere, because we haven't heard that Zhou Cheng has such a powerful Dan Sect powerhouse. ”

"Is that so?" Hearing this, Du Fei pondered for a moment before he said softly, "I'm afraid that I don't know what the opponent is, if we know what the other party is, we don't have to be too afraid, since the two of you have been able to fight for many years, it means that the strength of the two of you should not be far apart, so the strong man they sent out this time in order to prevent being taken advantage of by your housekeeper should be on the same level as you, right? If so, the hope is great...... It's just that everything is still careful, and after you get to the Necromantic Abyss, you follow me, understand?"

"Thank you, Big Brother Du Fei. Guan Ting nodded obediently, she now knew that if it wasn't for Du Fei's action that night, not to mention the loss of the housekeeper, maybe her little life would have to be lost there.

"Crunch—"

While the two were talking, the carriage, which had been moving slowly, suddenly stopped, and made a sharp and piercing sound.

Du Fei frowned, but he didn't speak, but Guan Ting's little head poked out for a moment before he retracted and said softly: "Brother Du Fei, we have reached the entrance of the Necromantic Abyss, and besides, there are many people around ......"

"Have you arrived?" Hearing this, Du Fei's eyes slowly looked out from the gap in the carriage.
