Zhang Fan thought about it for another day, but there was no progress in the slightest, originally thought that if this Nine Heavens Heart Thunder Decision and the Mixed Yuan Cutting Body Decision had the same principle, it should not be a big problem to practice, but obviously Zhang Fan still underestimated the complexity of this thunder method.

The most important thing is that after all, Zhang Fan has not been in the process of collecting the spirit for a long time, and what he has seen and heard is insufficient, so he is naturally a little puzzled by the concept of this thunder spirit, and it can be seen from here that knowledge is also a crucial factor for cultivation, without a certain amount of knowledge and experience, I am afraid that he can't even understand the secret book of this exercise.

And Zhang Fan seems to be facing such an embarrassing situation at the moment, seeing that Zhang Fan has been entangled for a long time, the old man still can't help but remind: "The so-called thunder spirit, the focus is not on the spirit, but on the thunder, don't forget that you are practicing the thunder method now, naturally everything is based on thunder, how can you focus on what spirit?"

Zhang Fan also suddenly realized something after such a little bit from the elder, "What do you mean, is this thunder refining spirit still thunder, not spirit? But if this is the case, this thunder refining has been completely cultivated in my body, why is there still no progress.........

Zhang Fan suddenly understood as he spoke, "I know, Elder Ming, do you mean that the third layer of thunder refining that I have practiced now is the thunder inside of me, and the thunder that I want to refine at the seventh layer is the thunder outside?"

"Even if you haven't been stupid yet, this thunder method is a technique known for its attack power, and it is not a mixed yuan sword that focuses on strengthening, you are almost complete in internal construction now, so naturally you have to show it to reveal the strength of this Nine Heavens Heart Thunder Decision, what is Heart Thunder? What is the thunder in your body now? You don't need me to tell you, right?"

Zhang Fan understood what the old man meant, so he closed his eyes again and fell into silence, because he was concentrating on feeling the Lei Dan that had now formed in his body, and what was lacking in the thunder in the Lei Dan, which was the most important problem that Zhang Fan needed to solve at the moment.

It's just that this Zhang Fan closed his eyes for nearly three days, during these three days, he completely felt every thunder in his body, and finally on the fourth day, Zhang Fan suddenly jumped up happily, and said excitedly: "I understand, I understand the elder, what my thunder lacks is the heart, and what is lacking is spirituality!"

The old man nodded with satisfaction and said: "Well, by the way, it is spirituality, think about it, what is the name of this thunder method? Nine Heavens Heart Thunder, the so-called Heart Thunder, could it be some ordinary thunder without the slightest rationality? Only with spiritual thunder can it soar above the Nine Heavens, isn't it? Four days, although it is a bit long, can it be regarded as qualified." ”

Zhang Fan was overjoyed, this kind of encountering huge difficulties and challenges, and then overcoming difficulties and solving challenges, maybe this is the biggest charm of attracting cultivators along the way of cultivation!

However, Zhang Fan was happy and happy, and he still understood that this problem was solved, and the next problem came, since his thunder lacked spirituality and heart, then how to give it spirituality? But with the encouragement of this successful comprehension, Zhang Fan was not discouraged at all, and continued to sort out his thinking.

"Elder Shen, you just said spirituality, but spirituality can only be spiritualized by living creatures, this thunder spirit, is it to find a thunder thing with spirituality? But where to find this kind of thing?"

The Elder continued: "Have you forgotten the Thunder Spirit Bead in your body? Have you forgotten the Thunder Dragon in the Celestial Realm when the Demon Shadow Bow was born before?

"That's right!"

At this time, Zhang Fan also remembered the matter of the Demon Shadow Bow before, the huge thunder dragon would even change the target of his attack, isn't this just a manifestation of spirituality? Not to mention the thunder spirit bead in his body, he can carry out the act of recognizing and protecting the lord, and his spirituality naturally does not need to be doubted.

But Zhang Fan was distressed again, "But it's still not good, Elder Shen, the thunder dragon caused by the Demon Shadow Bow last time was formed by the Thunder Tribulation, where can I find it now? And this seventh-layer Thunder Spirit refining obviously wants me to refine the spiritual thunder, how can I refine the Thunder Spirit Bead, it's not worth it." ”

The old man couldn't help but scolded again: "You kid, I just praised you, and I'm stupid, aren't I? Who told you to find the Thunder Dragon, and did I let you refine the Thunder Spirit Bead again? Isn't there a lot of thunder things with spiritual spirit in this large thunder lake in front of you, stupid you!?"

Looking at the rolling thunder lake in front of him, Zhang Fan couldn't help but laugh at his stupidity, "yes, isn't there something in the thunder lake in front of you that I don't know what it is?"

"That's right, although it is not clear what is in this thunder lake, but from the fact that they can survive so leisurely in this thunder lake full of thunder condensed, it shows that it is an extraordinary thunder creature after all, stinky boy, this seventh-layer thunder refining spirit of the Nine Heavens Heart Thunder Soul and the eighth-layer thunder soul are actually complementary to each other, and it is a natural step that can be undertaken, absorbing the spirituality of thunder things, in fact, is to absorb their thunder attribute souls, this is the true meaning of refining thunder spirits and transforming thunder souls. ”

"So that's the case," Zhang Fan suddenly realized, but after thinking about it, since this is the case, then Xiao Yi and Jian Tianfeng don't know if they understand this principle, if they don't understand, aren't they doing useless work when they practice to the last few layers?

The elder said: "That's the case, otherwise do you think that the people who left the Nine Heavens Heart Thunder Decision here were placed here by the way? This Thunder Lake is placed here with the Thunder Spirit Bead and this Thunder Law, it's not for nothing, if you don't understand the meaning of the word Heart Thunder, I'm afraid there will be no progress in practice." ”

Zhang Fan couldn't help but look at Xiao Yi not far away at this moment, looking at the thunder around her, her face was a little worried, it was estimated that she had encountered the same problem as Zhang Fan, Zhang Fan was not in a hurry to remind Xiao Yi, but it was not to worry about any competition with a child, but rather than let Xiao Yi take the risk of going to Thunder Lake, it was better for Zhang Fan to figure out what the living creatures in the Thunder Lake were first.

Zhang Fan then walked towards the Thunder Lake, as soon as he touched the lake, the Thunder Spirit Bead in Zhang Fan's body automatically stimulated a powerful thunderbolt to protect Zhang Fan's body, relying on him to walk slowly on the surface of the lake, the violent thunder in the lake was trying to break Zhang Fan's protection from the bottom up all the time.

Trying to pull Zhang Fan into the lake and accept the tearing of the ten thousand thunders, and the thunder spirit bead is naturally very powerful, no matter how the thunder below rushes, it can't shake the white thunder mangs around Zhang Fan's body, walked to the center of the lake, and looked at the dark purple thunder lake under his feet swimming in the black shadows that I don't know if it was hundreds or tens of thousands, and I was a little dumbfounded.

Because no matter what the living creature in it was, being able to wander so freely in this thunder lake full of thunder power was obviously not comparable to ordinary thunder creatures, and it could be seen from the size of the black shadow that its body was so big, Zhang Fan finally understood why Jian Tianfeng was seriously injured without even seeing his appearance clearly.

Those thunder fluctuations emanating from this lake, isn't that one black shadow at the level of a general? Zhang Fan smiled bitterly, "Old Man, play with me, right? This is equivalent to the thunder power fluctuations of the beast general, you let me suck their spirituality? You think too highly of me, right?"

The old man said angrily: "Didn't you kid come to kill the Dragon Emperor?

"............." Zhang Fan is sometimes a little speechless about the indecent style of the old man, I really don't know who it looks like, "Old man, stop playing, I don't know what is in the lake, you just let me go up?"

"Don't you still have Lei Lingzhu, are you? What are you afraid of, besides, you can still live and talk to me now, isn't it because Lei Lingzhu protects you? So, keep on hero, I won't rob you of your prestige. ”。

"But, but what's so big down here?"

The old man said disdainfully: "Cut, you don't care what it is, don't you know if you bombard it up?"
