In this way, Li Yunfeng passed half a month in this unbearable pain.

At this time, Mu Ling came out of the retreat, in fact, Mu Ling's retreat at this time did not have the slightest mood, because whenever he closed his eyes, his mind was filled with his father's kindness and love for him, and his mother was chased to death by the enemy in the early years, so Mu Ling took his father's love very seriously, but at this time, his father may have died, whether he should go back, and how to face the current "ruthlessness" after going back, Mu Ling is really a little confused.

It was also at this time that Mu Ling thought of Li Yunfeng to see if he had any good suggestions.

However, when his spiritual sense scanned the room where Li Yunfeng was, he was shocked, she didn't expect Li Yunfeng to choose to marry a baby at this time, she naturally knew how long Li Yunfeng's cultivation took to cultivate, cultivation really needs to be steady and steady, the most taboo is to rush forward, Li Yunfeng is too dangerous to do this.

However, Mu Ling also knew that Li Yunfeng must not be disturbed at this time, otherwise it would really kill Li Yunfeng!

Faced with such a scene, Mu Ling had no choice but to wait for Li Yunfeng's retreat to end, of course, Mu Ling was also a spiritual sense observing Li Yunfeng's movements all the time, if she was a little careless, she would rush in to help Li Yunfeng as soon as possible.

Unconsciously, Mu Ling had already regarded Li Yunfeng as so important, maybe even she herself hadn't known that she had begun to nervous about Li Yunfeng.

In the past few days, Qian Rou and Ziyue have also come out of the customs one after another, after all, this is in the secular world, the effect of retreat here is really not much, the spiritual energy is extremely scarce and dirty, even if they cultivate here for a hundred years, they may not be successful, of course, everyone has the spiritual energy spring water given by Li Yunfeng, otherwise they may have to consider whether to continue to stay here, speaking of which, Li Yunfeng has a lot of thoughts about Lan Jingjie. I don't know what kind of existence this thing is, the aura spring is slowly accumulating more and more in the Lan Jing Ring, even if he and everyone else are constantly using it, but it doesn't seem to have decreased in the slightest.

"Sister Mu, what are you doing here?" After Qian Rou and Ziyue came out, they were a little strange about Mu Ling in the courtyard, and they didn't know what she was doing here.

"It's nothing, how did you get out. Mu Ling has never had a good look at these people, if it weren't for Li Yunfeng's existence, he would even kill one by one like before.

"It's nothing. I just want to come out and breathe, there is Senior Brother Yunfeng's aura spring water, and our cultivation speed is very fast. And Qianrou, in fact, she has been preparing to get married during this time, so it doesn't matter if she retreats or not, as long as her state is adjusted and her preparation is sufficient. Although Mu Ling's temperament is a little cold, Zi Yue is still easy to speak, after all, the other party's realm is there.

Qian Rou and Ziyue saw that Mu Ling was sitting there and didn't speak again. That is, to leave quietly and not to disturb.

At this time, Li Yunfeng was almost at the end of the first step, and the pain in it really made Li Yunfeng a little unbearable. In particular, the exercise in the upper dantian made Li Yunfeng feel the urge to commit suicide, and he was overwhelmed! But fortunately, he endured it in the end.

Finally, on the twenty-eighth day, Li Yunfeng completed the exercise of the upper and lower dantians. Now it's time for the second step.

The second step is to refine the baby, and Li Yunfeng has naturally been prepared for this step for a long time, so when the first step is over, it will be the first time. Li Yunfeng was the Yuan Dan who urged the upper dantian to start smelting.

In fact, smelting Yuan Dan is also a little painful, but it is much milder than the first step.

Soon, Yuan Dan began to melt, as fiery red as a cloud of lava, the size of a quail egg.

In the past 20 days and almost a month, the spiritual power in Li Yunfeng's body can be described as surging, Li Yunfeng tried not to waste the slightest spiritual energy of the Demon Infant Pill, so the spiritual energy in his body is still extremely sufficient.

In fact, when you reach the stage of knotting, you can fully understand all the structures of your body, including every inch of skin, every bone, and every piece of muscle, so the smelting Yuan Dan at the beginning was very smooth.

A head the size of a soybean appeared in Li Yunfeng's upper dantian, which looked a little funny, if you look closely, you can find that this head is extremely similar to Li Yunfeng, it can be said that it is exactly the same.

Looking at the head of this villain, Li Yunfeng couldn't help but smile.

However, at this time, Li Yunfeng suddenly felt some abnormalities in his body, not because he was not concentrating on his mental strength just now, but because there seemed to be a desolate aura in his body that suddenly appeared, at this moment, not only Li Yunfeng sensed it, but Long Kui on Li Yunfeng's wrist also opened his eyes, savoring this feeling of nothingness, and looked like he was enjoying it.

And Mu Ling outside the house was also a little confused, but she didn't rush in, but just waited here quietly, her spiritual sense has been paying attention to Li Yunfeng, as long as Li Yunfeng is not in danger, she naturally will not take the initiative to go in.

Li Yunfeng stopped smelting Yuan Ying, but instead carefully understood the source of this breath, he had a feeling that the source of this breath was his body.

Could it be the little dragon?

Now there is only one explanation.

But now thinking of this little dragon, Li Yunfeng has a strange idea, he has a strange sense of the dragon itself, why not try to smelt his Yuan Dan into a dragon form?

As soon as he said and did it, Li Yunfeng immediately re-smelted the originally smelted head.

In another few days, Li Yunfeng's Yuan Dan in the dantian finally appeared a dragon head, this dragon head was lifelike, and it was very powerful. It is different from Long Kui, and it is not the same as the little dragon in Li Yunfeng's original dantian, this is completely the appearance of a dragon in Li Yunfeng's own imagination, and it can be said that Li Yunfeng's own understanding of the image of the dragon.

Another half a month, Li Yunfeng's dantian in the little dragon finally smelted completely, if someone can enter Li Yunfeng's brain, will be surprised by the power and vastness of this dragon, this dragon is not big, only less than two inches long, but the whole body is glowing with golden light, and the most bizarre thing is his eyes, the eyes are dark green, very crystalline, but it also makes people feel a sense of horror.

The next thing is naturally the smelting of the lower dantian, the smelting of the lower dantian is very smooth, much faster than the first smelting, but when the tail is finally smelted, Li Yunfeng suddenly has a feeling in his heart, after this dragon is smelted, I am afraid that it will not exist for long before it dissipates and becomes Yuan Dan again.

It's all a telepathic feeling, a sense of familiarity with one's own body! (To be continued......
