After some tossing, Sun Fei and Lingji still survived the second level without danger.

This time, Sun Fei obviously felt that the degree of qi growth in his body was not as good as the previous level, and it seemed that the increase in cultivation was indeed directly proportional to the degree of output in each level.

The number of people who appeared in the third level was also six as Sun Fei expected, but this time it was even more exaggerated, and five of the six clones were fake spirit girls.

Although the five fake spirit queens were not easy to deal with from both an offensive and defensive point of view, with Sun Fei's excellent combat awareness and spirit Ji's innate combat talent, the six clones didn't last long, and they all turned into green light and returned to the earth.

Sun Fei's heart is still a little nervous at the moment, if it is true that the enemies that appear in each level have become doubled, then in the next level, it is really very likely that two strong people will appear directly.

Sure enough, soon, two figures appeared on the opposite platform, namely the ninety-nine Ruan Ying and the nineteenth West Jue, and even the strong ones that appeared were the same as when they challenged themselves, and it seemed that when Jiuyuan Mirror chose the strong ones, they were also selected according to the personal combat style of each challenger.

At this moment, Ruan Ying was holding a handful of sugar gourds in her hands, and her small mouth was still chewing, still eating something every time she appeared.

Seeing Sun Fei and Lingji appear at the same time, Ruan Ying was also slightly surprised, and then showed a soft smile to Lingji and said, "Lingji, you have grown a lot...... Well? ”

At this moment, Ruan Ying seemed to see something, and asked suspiciously: "You have more of this person's qi in your body, have you double-cultivated with this masochist?" ”

Lingji's pretty face suddenly turned red, and she nodded her little head slightly.

"Well, you're ...... Let me say what's good, it's not good to choose a man, but I want to choose this masochist, my sister's eyes...... How so. ”

Sun Fei heard a masochist in one bite, and he couldn't bear it anymore, so he coughed twice and said, "You wait a while, and explain who is a masochist first?" I? Are you sure you're talking about me? ”

However, Ruan Ying ignored Sun Fei gorgeously, and turned to the West Juezi next to her and said, "If it's not the first time that Ling Ji has cultivated with the Nine Yuan Mirror, you must have fought with her before, why don't you tell me?" ”

Xijue suddenly showed an embarrassed expression and said: "It's true, but we just fought once, and that time I was almost repaired by your precious sister, so I'm embarrassed to say it." Besides, how did I know she was your sister......"

"Oh......?" Ruan Ying squinted her eyes slightly, and gradually released a rather majestic dragon pressure, and saw that the West Juezi showed an extremely aggrieved expression, so she snorted and put away the coercion.

Ling Ji, who saw Ruan Ying, also looked extremely excited, and said excitedly: "By the way, sister, I can use dragon qi now!" ”

The grim expression on Ruan Ying's face immediately turned into a gentle smile, and she nodded lightly and said, "It's true, but, my sister is curious, how did you raise your cultivation to this level in such a short period of time?" ”

Therefore, Ling Ji and Sun Fei roughly explained to Ruan Ying the problem of using the Nine Yuan Mirror to form the conditions for dual cultivation and then quickly improve their cultivation.

After listening to the words of the two people, both Ruan Ying and Xijue showed a puzzled expression.

Seeing the two of them showing such expressions, Sun Fei was even more puzzled, and couldn't help asking, "Is there any problem?" ”

Ruan Ying thought for a moment and said, "I've also heard that many people who have ascended to the Immortal Dao use the method of double cultivation to cultivate, but just through double cultivation, they can exchange the qi in their bodies...... This is the first time I've seen this happen. ”

Xijue also chimed in: "That's right, although your statement sounds reasonable, but in fact, it is impossible to exchange the qi in the body just through double cultivation, let alone the bloodline power itself. ”

Sun Fei suddenly felt that the problem seemed to be a little bigger than he imagined, could it be that his previous speculations were wrong?

"No, but, there is no doubt that we did exchange qi through double cultivation...... Forget it, I already have a way to verify this matter, and I'll tell you when I verify the authenticity of this matter. As Sun Fei spoke, he suddenly realized that he had a better way to test his hypothesis.

Lou Zuoying has the power of bloodline in his body, and after a cultivation of the Nine Yuan Mirror, the qi in Lou Zuoying's body has swelled to a daunting point. With the conversion rate of this bloodline qi in her body, it was easy to see if she could exchange the qi in each other's bodies through dual cultivation.

If you can also exchange qi with Lou Zuoying in double cultivation, then your hypothesis should be verified.

Thinking of this, Sun Fei made up his mind, and when Lou Zuoying came to the door again later, he would try to verify it.

The challenge of the third level is obviously too high for Sun Fei and Ling Ji. On the one hand, Lingji lacked sufficient combat experience, and she couldn't hurt the West Jue of the Earth Immortal level at all with her combat talent alone. In addition, there was also a celestial-level Ruan Ying in charge, even if Ruan Ying was obviously merciful to Ling Ji, the two of them were still beaten back.

After exiting the Nine Yuan Mirror, Sun Fei immediately probed the situation of himself and Ling Ji's internal qi with his heart, but was surprised to find that his cultivation had actually broken through!

The final battle with the two immortal-level powerhouses consumed both Sun Fei and Ling Ji to the point where it could almost be said that they were exhausted. But the benefits of such cultivation are naturally very obvious, and Sun Fei's breakthrough is the best proof of this.

After the breakthrough, Sun Fei took a cursory look and found that his qi had become less.

After taking a closer look, Sun Fei found that his qi had not become less, but had changed from its essence, and his Xuan Qi had become more condensed!

I see, it seems that when my cultivation is raised to a new level, my Xuan Qi will also undergo certain changes.

Now his Xuan Qi is more tense than when it was in the second layer, on the one hand, it can be controlled more finely, and on the other hand, it is also more condensed, and the Xuan Qi Sword formed must be more penetrating than before.

Soon, Sun Fei discovered that he could now learn the remaining full set of Xuanqi swordsmanship.

Not only was he able to learn the Xuan Qi Sword Technique, but Sun Fei also automatically learned a brand new skill from the Immortal Doctor True Scripture: Xuan Ling Gu.

This skill is unlike anything I've seen before, and it's a powerful skill that can almost be said to be a killer!

The so-called Xuan Ling Gu is to select a spiritual weapon as a container for Xuan Qi, inject a trace of Xuan Qi containing life elements and spiritual wisdom into it, let this spiritual weapon be used as its shelter, and constantly cultivate it, so that it becomes more and more powerful.

Xuan Ling Gu can not only be used to practice medicine, especially in the face of some incurable diseases, Xuan Ling Gu can clear the root of the disease more efficiently than the Xuan Qi controlled by Sun Fei himself, the key reason is that Xuan Ling Gu is intelligent, so it is more comprehensive and more agile in the human body than Sun Fei to observe with his heart and eyes, or through Xuan Qi.

And the most critical place is that the Xuanling Gu is also an absolute weapon to kill the enemy. Once it is released from the artifact, it can hide into the air, and if it reaches a certain level, it can even hide into another dimension. When it gets close to an enemy, it enters their body and instantly disintegrates them from within.

It can be said that once the Xuan Ling Gu is successful, even if it is an earth immortal-level powerhouse, it can be killed!

And since the Xuanling Gu is called "Gu", it naturally has the characteristics of Gu.

The process of cultivating the Xuan Ling Gu is to feed it Xuan Qi and let it continue to grow. Having it fight with its host will also increase its intelligence, eventually growing into a terrifying being.

At this moment, Sun Fei suddenly thought of the mysterious powerhouse he had met before.

If she remembered correctly, she released an extremely subtle trace of Xuan Qi from the ring at that time, and then killed Lou Zuoying in seconds, but she couldn't see how she did it.

Could it be that at that time, that mysterious powerhouse was using this kind of Xuan Spirit Gu?

Sun Fei frowned slightly, it stands to reason that now there is only one heir of the Immortal Doctor True Scripture, and there will be no second heir, so what happened to the mysterious powerhouse he met before? Could it be the ancient immortal doctor true scripture descendant?

Forget it, it's useless to think about these now, let's think about it first and see how to find a suitable spirit weapon and cultivate your first Xuan Spirit Gu.

"Sun Fei, Sun Fei! My cultivation has increased again! At this moment, Ling Ji's excited voice interrupted Sun Fei's thoughts.

Sun Fei was stunned for a moment, and after taking a closer look, he found that the qi in Ling Ji's body had indeed improved a lot, especially the increase in dragon qi was particularly obvious.

From almost nothing in the original, to a little bit later, and now it is almost comparable to the void qi in the body, it can be seen how fast this growth has to be!

Sun Fei smiled bitterly and shook his head lightly and said, "Ha, I think you will be able to turn into a dragon in a short time, and by that time, maybe I won't be able to beat you." ”

Lingji immediately raised her little face and said proudly: "Of course, even now you can't beat me!" So you're willing to admit my strength, right? ”

"Yes, yes, I admit your strength, you are the best." Sun Fei shrugged his shoulders and continued to hold Lingji. Looking at Ling Ji's appearance of kicking her nose and face, Sun Fei only felt that she was a little cute, but she couldn't keep her face cold.

At this moment, Ling Ji snorted lightly and said, "Now that you understand, you are not allowed to double cultivate with other women in the future, do you know?" ”

"What? What does this have to do with double cultivation or not? A layer of cold sweat suddenly broke out on Sun Fei's forehead, how could this little girl always think about this.

Ling Ji's pretty face turned slightly red, her eyes seemed a little wandering, and she murmured in a low voice, "Total, in short...... You memorize it for me, otherwise...... I, I can't spare you! ”
