That's right, it is the two qi of yin and yang in the body, the Tao of Tai Chi, the beginning of yin and yang, and yin and yang are the birth of all the life energy in this world, and this explains why Zhang Fan dared to boldly change the practice order of the Nine Heavens Heart Thunder Decision, and this is undoubtedly similar to Zhang Fan's existing basic principle of the Mixed Yuan Cutting Body.

And this is all cultivation, driving the yin and yang qi in one's body, the only difference is that one of the two is the surface, one is the inside, one is static, and the other is moving, the mixed element is used to act on the body surface and strengthen the body, and the Nine Heavens Heart Thunder is used internally, turning on the thunder power, and the mixed element is determined to pay attention to the replacement of yin and yang, relying on each other, so as to burst out of strong energy to support the body, but the Nine Heavens Heart Thunder is focused on the interaction of yin and yang, rubbing against each other, so it produces a strong thunderbolt to strengthen its own attack.

The two seem to be very different from each other, but in fact, the principles are interconnected, and only Zhang Fan, a person who has practiced the Mixed Yuan Cutting Body, can see the connection between the two.

In other words, the only person who can practice the Nine Heavens Heart Thunder Determination Method like this is probably only him Zhang Fan in today's world, but what makes Zhang Fan overjoyed the most is that not only may this Nine Heavens Heart Thunder Determination not be as difficult for him to practice, but also that this principle is a two-sided mirror.

Because Zhang Fan realized one thing from this, since after he practiced the Mixed Yuan Cutting Body Decision, the cultivation of the Nine Heavens Heart Thunder Decision was twice the result with half the effort, then for those who practiced the Nine Heavens Heart Thunder Decision, wouldn't it be the same thing to practice the Mixed Yuan Cutting Body Decision again, and it would be a matter of course?

Therefore, in other words, the Mixed Yuan Cutting Body Determination is a top-level body method, which has an unparalleled effect on strengthening one's own body, so wouldn't it be more convenient to let Jian Tianfeng and Xiao Yi, who have now practiced the Nine Heavens Heart Thunder Determination to a certain extent, practice?

Zhang Fan's eyes lit up even more when he thought of this, Xiao Yi needless to say, of course he wanted to do everything he could to arm and strengthen Xiao Yi, so that even if he was not around that day, Xiao Yi could protect himself, and Jian Tianfeng, as the commander of the Spirit Department, probably needed such strength more than Xiao Yi.

Therefore, Zhang Fan is planning to find a suitable time to verify his idea, if it succeeds, this is for the Nine Heavens Heart Thunder Decision and the Mixed Yuan Cutting Body Determination two exercises, but there are two completely different cultivation directions, even if they are not proficient in thunder power, they can also use the Mixed Yuan Cutting Body Determination as a starting point and cultivate both, which is undoubtedly a big surprise for the Spirit Department, of course, this is a little too early for the current Spirit Department.

And the idea in Zhang Fan's heart naturally couldn't be concealed from the old man, but the next words of the old man made Zhang Fan more confident in the feasibility of this idea, "Well, the idea of the stinky boy is very good, and in my opinion, it is indeed very feasible, I didn't expect your kid's head to be very good, which can make you notice the connection and commonality between the two, and it seems that it can only be said that it is destined to be your thing." ”

Even the elder recognized his idea, and Zhang Fan was even more eager to try, but he wouldn't just go to Xiaoyi or Jiantianfeng to test, of course, he verified his own idea first, even if he made a mistake with the maintenance of the Lei Ling Clan, it wouldn't be too big a thing to think about, Xiao Yi They didn't have Lei Lingzhu, so Zhang Fan continued to practice first.

The time of a day is actually very fast, especially for the two people who are pouring their whole bodies into cultivation, but Zhang Fan's idea is not out of nowhere, the reality has fully affirmed his idea, I saw that in less than a day, Zhang Fan's body was covered with thunder, and countless small thunderbolts began to flicker everywhere on Zhang Fan's body.

This is the sign of the first layer of gathering thunder to cultivate the Dacheng, and Zhang Fan is not just as simple as cultivating the first layer of the Dacheng, in his body, a mass of thunder force formed by the aggregation of a large amount of thunder began to form in his heart, with the beating of the heart, every minute and every second is bursting with a rich thunder power to all parts of the body.

Zhang Fan's eyes suddenly opened at this time, and the powerful thunder burst out from between the opening and closing of his eyes, like two wild horses that had escaped from the reins, startling the thunder lake in front of him with a lot of waves, Zhang Fan looked at his body with satisfaction, "Great, I didn't expect this Nine Heavens Heart Thunder Decision and Mixed Yuan Cutting Body Decision to be so compatible, the first layer of thunder gathering has been practiced and completed, and the fifth layer of thunder gathering heart has also been formed and has begun to have a small success, this speed is not bad, I am very satisfied, hehehehe......."

"Hey, I said that you stinky boy just got a little sweetness and is so complacent, as for it? ”

"Okay!~" Zhang Fan was completely immersed in the fun of cultivation at the moment, perhaps this is also the state that the old man wants to see the most.

And the sound made by Zhang Fan naturally made Xiao Yi, who was not far away, notice, Xiao Yi felt the rich thunder breath coming from her brother's side, and couldn't help but rejoice: "Brother is really amazing, how long has it been, the first layer has become? A day faster than me, no, I have to work hard, I must take my brother to play...........

Time passes day by day,

In these five days, Zhang Fan has not moved his position for half a minute, at this moment the land within a radius of five meters around Zhang Fan is a pitch-black scorched earth, it is obvious that these traces are caused by Zhang Fan's practice of thunder, at this moment his thunder roars without being exposed, the electricity flashes without dissipating, and the whole thunder Buddha sits in it.

Although there is no thunder power on the body, there is endless thunder inside the body, as if there are countless thunderbolts in Zhang Fan's body intersecting and raging, making people feel a sense of horror when they hear it, "bang bang bang........." The surface of his body even kept bursting into explosions.

The thunder power is all restrained, which is the manifestation of this third layer of thunder refining, at this moment Zhang Fan's thunder has been completed, the thunder has been condensed, and the thunder refining has been complete, with the blessing of this thunder spirit bead, the second layer of thunder condensation is to condense the thunder in his body, which is almost no problem, and the thunder air mass in the body has gradually converged and condensed into a small thunder dan.

Seeing that he was about to hit the fourth layer, but Zhang Fan felt some obstacles, and couldn't help but continue to look at the Nine Heavens Heart Thunder in his hand and decided, "What's going on, obviously refining thunder is just refining your own thunder form with your own mind, I have clearly done it, but why is this fourth layer so uncomfortable for me, why?"

Zhang Fan combined the explanation of the seventh layer of thunder refining spirit and the eighth layer of thunder soul, but he still didn't know what this meant from the seventh layer to the thunder refining spirit, Zhang Fan originally thought that he didn't understand the seventh layer of thunder refining spirit when he practiced the third layer of thunder refining, so he would be hindered.

But I didn't expect that this third layer had no feeling of hindrance, everything was going well, but the seventh layer of the thunder spirit refining could not be practiced, and even the sixth layer of the thunder spirit was condensed, why didn't this thunder spirit know what it was? The previous first and second layers and the fifth and sixth layers were all connected with each other and naturally, but the third and seventh layers seemed to be completely separated, which made Zhang Fan puzzled for a while.

Although the third layer can be practiced, but the fourth layer is completely unmoved, no progress, Zhang Fan carefully studied and came to a conclusion, all in all, Zhang Fan did not understand enough of the thunder spirit of the seventh layer of refining thunder spirits, originally Zhang Fan still thought that with the practice of the third layer, maybe the answer could be called out, but obviously he was a little too optimistic.

"What is this thunder spirit?spirit?spiritual power?soul?But yes, this thunder spirit refers to refining one's own thunder soul, then what is this eighth-layer thunder soul? It can't be that two layers of exercises are to cultivate two thunder souls, right? This is impossible.........
