Back to Zilei,

At this moment, Zhang Fan is already on the shore of the huge thunder lake under the spiritual department, looking at the huge thunder lake, which is still full of surging thunder, Zhang Fan is almost forgetting that this thunder lake is so shocking, thinking that since the last time he discovered this underground secret land, Zhang Fan has never been here again.

In the past few months, the materials for refining the furnace tripod with rare attributes have also been taken by Senior Brother Zigu and Elder Dong, and every drop of the tumbling lake in this thunder lake is full of rich thunder power, and the depths are even more thunderous, which is terrifying, and the undulating waves in it reveal the huge black figure in the lake from time to time.

Obviously, no matter what kind of creature is in this thunder lake, its size will not be small, and it can survive in this kind of thunder lake full of thunder and thunder power is so strong that it condenses into water, no wonder it is that even the general-level master Jian Tianfeng, who cultivates the thunder method, is planted, Zhang Fan opened the Nine Heavens Heart Thunder in his hand and studied it carefully.

"There are nine layers of thunder in the heart of the Nine Heavens, nine layers of thunder and nine layers of law, Lei Cheng's heart is shocking, the practice of this thunder law is also full of domineering, you must be deep under the bombardment of thunder, to feel the power of thunder, accept the baptism of thunder is to retain the thunder, and the thunder lake in front of you is obviously the best place to feel the thunder. ”

Xiao Yi also said on the side: "Brother, this Nine Heavens Heart Thunder is by no means so difficult, I have only been practicing for more than a month, and I have already reached the third level of thunder refining, my brother is so smart, he must learn faster than Xiao Yi." ”

The nine layers of the Nine Heavens Heart Thunder Decisive are Gathering Thunder, Condensing Thunder, Refining Thunder, Turning Thunder, Gathering Thunder Heart, Condensing Thunder Dan, Refining Thunder Spirit, Turning Thunder Soul, and Wishing Heart Thunder, although I don't know how difficult the specific practice of this thunder method is, but judging from the fact that it has taken more than ten years to practice the incomplete Thunder Law before, its difficulty will definitely not be small.

But at this time, Xiao Yi actually said that it was not difficult, and it only took him more than a month to cultivate to the third level, which shows that Xiao Yi's talent is not low, Zhang Fan naturally understands that this is probably more dependent on Xiao Yi's natural spirit physique, but it also understands why Li Lao and they spoil Xiao Yi so much, and Xiao Yi may be much better than his so-called genius.

Zhang Fan listened to Xiao Yi tell him about her understanding and experience of the first layer, he was very happy to see such Xiao Yi, at least Xiao Yi was no longer immersed in the pain of losing her grandfather as before, and regained her previous smile, which made Zhang Fan very happy, looking at the essence of the watery eyes, Zhang Fan knew that Xiao Yi in front of him was a soul collector who focused on cultivation.

"Brother, brother, have you heard of it?" Seeing that Zhang Fan seemed to be in a daze, Xiaoyi called him, "Brother, why are you in a daze, is Xiaoyi not clear enough?"

"No, no, it's my brother who just shook his head, I'm sorry," Zhang Fan didn't want Xiao Yi to delay his practice for his own sake, so he said to Xiao Yi, "Xiao Yi, otherwise it's better to let my brother practice by himself, you can continue to practice, you have to become stronger, then you don't need anyone's protection, brother can rest assured, okay?"

Xiao Yi pursed her lips, "No, is Xiao Yi wrong?" I want to practice with my brother, it's more fun." Zhang Fan could only smile bitterly and continued: "Xiaoyi, this practice is generally a matter of personal opinions, so let's do it, brother, just practice by yourself first, and then ask you if you don't understand?"

"Hmm............" Xiaoyi was still a little reluctant.

"Otherwise, how about Xiaoyi and her brother come to compete together?"

Xiaoyi was instantly aroused by interest when she heard it, after all, it was a child's heart, "What game??"

"In the next month, none of us will help anyone, so we will practice the Nine Heavens Heart Thunder Decision according to our own understanding, and finally see who can practice the fastest, how about it? If Xiao Yi wins, how about my brother promise Xiao Yi to take you to the Imperial City for fun?"

Xiao Yi's eyes were shining with gold, and she looked at Zhang Fan excitedly: "Really, really, brother, brother really took Xiaoyi to have fun?"

Touching Xiaoyi's head lovingly, Zhang Fan smiled and said, "Of course, when did my brother lie to you, but this is also up to Xiaoyi to win, how about it?"

When Xiao Yi heard this, she hurriedly crossed her waist with her two little hands and said very confidently: "Of course, Xiao Yi is not the same as before, now Xiao Yi is strong, brother don't lose and don't admit it, pull the hook." ”

"Okay, the hook will not change for a hundred years!"

The two of them were separated from each other and started their own practice, although this is a bit unequal for Zhang Fan, after all, Xiaoyi has already practiced the first three layers, and she can directly impact the fourth layer, but this so-called competition is just an excuse for Zhang Fan to let Xiaoyi concentrate on her own practice.

Compared to Xiao Yi sitting cross-legged on the side and concentrating on the thunder power, Zhang Fan's side seemed much more leisurely, Zhang Fan was not in a hurry to immediately practice according to the Nine Heavens Heart Thunder Decision, but instead spent nearly a day carefully studying the entire thunder method.

And it turns out that Zhang Fan's approach is right, because from the understanding he has seen, this is not the Nine Heavens Heart Thunder Decision seems to be practiced layer by layer, but there is also a subtle connection and change between the layers, just for the first layer of thunder, ordinary people pay attention to step by step, layer by layer gradually practice breakthroughs, I didn't expect that this thunder gathering and the fifth layer of the thunder heart in the back have the same effect,

Although the fifth layer naturally seems much more mysterious, but its principle is still based on the first layer, after overlooking the whole book, Zhang Fan decided to change the order of practice, but the reason why Zhang Fan dared to try so boldly was because he had an advantage that others said he didn't have, that is, Lei Lingzhu and Mixed Yuan Cutting Body.

Compared with ordinary people, I don't know how much stronger my physique, plus Lei Lingzhu's natural sensitivity to Lei Li, for the first step of Lei Li's touch, it is extremely easy for Zhang Fan, don't talk about others, let's just say Xiao Yi, Xiao Yi's natural spirit body is much more sensitive to various forces, but even so, it took her almost three days to feel the thunder power of the outside world, and contact and link it with her own spiritual power.

And now Zhang Fan, in less than a few hours, is very clearly aware of the thunder power from the outside world is pouring into his body, since it has such an advantage, Zhang Fan is naturally overjoyed, while the iron is hot, with the passage of time, Zhang Fan only took two days to successfully practice the fifth layer of the thunder heart.

The so-called gathering thunder heart is to condense a thunder energy mass in one's own body, the purpose is to gather the thunder power in the outside world and one's own body, so that it will not pass, and it should be said that before this thunder heart, the practitioner must go through the strong baptism of thunder, but for Zhang Fan's body, who has long been unknown how many times the thunder power has been attached, the thunder power from the outside world has already entered Zhang Fan's body without hindrance.

And Zhang Fan's own thunder power in his body is not to mention, others also need to condense thunder, refine thunder, and turn thunder into these steps to be able to use the external thunder force as a medium to open up the thunder force between the energy interactions of cells in his body, and on this basis is the step that can gather thunder hearts.

But don't forget that Zhang Fan doesn't need it at all, because he has the thunder spirit bead of Ten Thousand Thunder Venerable in his body, and it is easy to open Zhang Fan's own internal thunder power, but Zhang Fan is also surprised to find a very coincidental thing, the so-called thunder force between the energy interactions between cells in the body, to put it bluntly, is just to run the two forces in the body, so that they rub against each other to produce thunder and lightning energy, and the coincidence is precisely here, because in the existing life body, the two most prosperous forces are nothing more than yin and yang。
