"It seems like so, Senior Brother Lu, aren't you like that?" asked Li Fengyun.

"Of course not!" Lu Jinghong said, "Little junior brother, you should know that there are many kinds of spiritual energy between heaven and earth. Martial arts practitioners, because of the difference in physique, can only absorb one or several of them. ”

Li Fengyun nodded, this is the basic common sense of cultivating martial arts, of course he knows.

There are many kinds of aura between heaven and earth, which can be roughly divided into five categories: metal, wood, water, fire and earth, which are divided into yin and yang, and in the yin and yang qi, they are divided into pure yin, pure yang, miscellaneous yin and miscellaneous yang, corresponding to the heavenly and earthly branches, and there are as many as 32 kinds of types. Ordinary people, at most, can only absorb three of these aura. Before Li Fengyun, he could only absorb the pure yang aura of the wood system Wuchen and the pure yang aura of the gold system Gengshen.

The aura between heaven and earth is absorbed into the body, and after passing through the dantian, it turns into the internal force of the true element, which can only be used by the inhaler, and this process is like stamping the aura with a seal. Before Jin Dan gathered, it was not easy to stamp these aura, so the internal force increased relatively slowly. And after gathering the golden pill and becoming a first-class master, it becomes very easy to stamp the aura, so the speed of internal force improvement is very fast. But no matter what you say, Jin Dan will not stamp other kinds of aura.

After lighting the heart lamp, Li Fengyun felt that the speed of stamping had increased several times, and the limit of the dantian had also expanded several times. Not only that, but the heart lamp is no longer picky about all the aura, and it does not refuse. No matter what kind of aura, as long as it is tempered by the heart lamp, it can be transformed into a wood-based Wuchen Pure Yang True Yuan and a gold-based Gengshen Pure Yang True Yuan, which is simply wonderful.

Li Fengyun originally thought that all the masters who lit the heart lamp should be the same as him, but now that he heard Lu Jinghong say this, it is obvious that his heart lamp is not the same as other people's.

"As far as I know, even the supreme master can only absorb the aura that matches it, and it is impossible to absorb other kinds of aura. Little junior brother, your heart lamp is so wonderful, I am afraid it is related to the Northern Spiritual Skill you have cultivated. Lu Jinghong thought for a while and said, "Only the Northern Spiritual Skill can absorb other kinds of spiritual energy and absorb the true essence of others." It seems that this Northern Spiritual Skill is really not simple!"

True Yuan, or True Qi, internal force, is essentially a kind of aura, the difference is that it has been stamped by people.

In fact, if the stamped true yuan is left alone for a long time, the mark on the true yuan will slowly fade until it turns into the most primitive aura. The imprints on the true elements of second- and third-rate masters are relatively light and easy to disperse, so second- and third-rate masters must always work hard and constantly strengthen the imprints of true element injuries, which also affects the speed at which they absorb true elements. It is not so easy for the imprint on the true yuan of a first-class master to dissipate, and under normal circumstances, it may not be able to dissipate in more than ten years. The mark of a peerless master, like a knife and an axe, will truly dissipate after a few decades.

The Northern Spiritual Skill, to put it bluntly, is actually a kind of miraculous skill that washes off the mark on the true element of others, and then transforms it into the true element that you match. Obviously, it is inseparable from Li Fengyun's strange heart lamp. It's just that the original Northern Shengong obviously can't completely convert other people's true elements into matching true elements, which contains a lot of impurities, and over time, it will inevitably erode the dantian and make the dantian texture decline. With the passage of time, the true elements of different provenances will also slowly grow, conflict with each other, and it is difficult to blend with each other. This leads to madness.

"Little junior brother, your experience is really enviable!" Lu Jinghong sighed, "To be honest, junior brother, is there really no difference between the Northern Spiritual Skill you practice?"

Li Fengyun shook his head and said, "Senior brother, I really don't know this, I only know that the Northern Spiritual Skill is very easy for me to connect, it seems that I would have known this Divine Skill, and I don't know anything else." Li Fengyun knew that Lu Jinghong was suspicious, so he had to perfunctory his words.

It's not that Li Fengyun is reluctant to tell Lu Jinghong about the Northern Spiritual Skill, but that Lu Jinghong doesn't have the seeds planted by Li Cangqiong in his body, and he is not suitable for cultivating the Northern Shengong. Moreover, Li Cangqiong was plotted by his disciples back then, who exactly plotted against Li Cangqiong, and now Li Fengyun is not exactly sure, he only knows that that person assassinated Li Cangqiong back then, in order to get "Northern Shengong" is one of the reasons. Compared to Yan Wushuang, his Senior Brother Lu seemed to be more enthusiastic about the Northern Spiritual Skill, and Li Fengyun naturally had more suspicions about him.

"Senior brother, do you want to practice the Northern Spiritual Skill?" After a long time, Li Fengyun asked lightly.

Lu Jinghong smiled bitterly and said: "It's not that I want to practice, it's just that according to the news you got from Mo Qingxing's mouth, the person who assassinated the master is quite interested in the "Northern Spiritual Skill", and it seems that there is indeed a great secret hidden in this "Northern Spiritual Skill". I want to avenge my master, and I also want to learn from "Northern Shengong" to see if I can take a step forward, so I care so much about Beishen Shengong.

I taught Leng Yuxuan to cultivate the Northern Spiritual Skill, and its purpose was just for this!

What's the matter, junior brother, do you suspect that I am the one who plots against the master?"

Li Fengyun was silent and didn't answer, and only said for a long time: "Senior Brother Lu, you said that the master will accept a fourth disciple in addition to Senior Brother Yan, you and me?"

Lu Jinghong was stunned for a moment, and replied, "I can't say for sure." It stands to reason that if Master accepted other disciples, it would be impossible not to tell Senior Brother Yan and me. Unless ......"

"Unless what?" asked Li Fengyun.

"Unless Master was like me back then, wanting to get enlightenment from the Northern Shengong, and worrying that it would cause misunderstanding if it was known. Lu Jinghong pondered.

"Ghost Shura!" Li Fengyun called out, "No, Ghost Shura can't secretly calculate the master, and the age is not right." That's right, it's the master of the ghost Shura!"

"Ghost Shura's master?" Lu Jinghong's eyes were a little strange, and he asked, "Who is that? Isn't it rumored that Ghost Shura is dead?"

Li Fengyun shook his head and said, "I don't know about this, the ghost Shura is not dead, I have seen him." In short, if you want to uncover the unsolved case of the master, you have to start with the ghost Shura, otherwise, I am afraid that the suspicion on Senior Brother Yan and you will never be washed away. ”

Lu Jinghong pondered for a moment and said, "There is also this possibility, junior brother, don't think so much, it is important to cultivate your body." Naturally, I will find out about the ghost Shura. ”

Li Fengyun snorted and closed his eyes to recuperate.

Lu Jinghong stood in front of Li Fengyun's bed for a long time before turning around and leaving.

Listening to the footsteps of Lu Jinghong leaving, Li Fengyun opened his eyes, turned his head sideways, looked at the empty door, and said silently in his heart: "Senior Brother Lu, don't blame me, don't do this, I really can't judge your innocence." I really hope that Daddy Li really has another apprentice! Otherwise, teach me how to meet you?"
