Tang Xu's next learning was the Rainbow Thunder Fist, originally thought that with the experience of the Dragon Xingjiu Style just now, it would be easier to learn, but Tang Xu was wrong, and it was very wrong. These are two completely different martial arts, the Dragon Movement Nine Styles is simply a use of true qi, and the Rainbow Thunder Fist is more difficult to learn than the Dragon Movement Nine Styles, what is required is to master the power of thunder and lightning, and even absorb the power of thunder and lightning from the outside world. Tang Xu already had the previous Longxing Nine Style formula, and it was difficult to change it for a while, which made Tang Xu learn and take a lot of detours.

Tang Xu still looked at the Rainbow Thunder Fist as a whole like he did in the cultivation of the Dragon Xing Nine Styles, and had a general understanding. Rainbow Thunder Boxing, as the name suggests, is the use of thunder and lightning to attack the boxing method, thunder and lightning can be said to be the nemesis of all immortal cultivators, every immortal cultivator large and small will experience some thunder tribulation, if you are not careful, you will die, the body can not stay, directly turned into smoke and dust scattered in the world. Therefore, it is not an exaggeration to say that thunder and lightning are the nemesis of all immortal cultivators, if Tang Xu can master the power of thunder and lightning, then it can almost be said to be invincible in battle, of course, the premise is that when the strength of the two sides is not much different, the difference in strength is too great, no matter how many skills there are, it is useless.

Tang Xu separated a part of the thunder and lightning from the dragon axe, this exercise is prepared for immortal cultivators who have the power of thunder and lightning in their bodies, Tang Xu can't produce thunder and lightning in his body, but it's not that he can't cultivate at all, it's just a little troublesome. The source of thunder and lightning can only be found from the outside world, and in this cave, there is no thunder and lightning, only some can be separated from the dragon axe, and when Tang Xu's strength is stronger, he can cite the thunder and lightning in the outside world, after all, it is endless.

Thunder and lightning covered Tang Xu's right hand, Tang Xu's right hand seemed to be wearing a pair of blue gloves, but it was composed of thunder and lightning, making a crackling sound, which could explode on Tang Xu's hand at any time, and Tang Xu could even see a kind of burnt black covering the entire palm.

Tang Xu carefully controlled the thunder and lightning, walking on thin ice, all he had to do now was to stimulate his hands with thunder and lightning, so that his hands could adapt to the intensity of the thunder and lightning. Now, Tang Xu was enduring the pain caused by thunder and lightning every minute and every second, as if tens of thousands of ants were gnawing on their fingers, and as if they were pricking Tang Xu's hands with countless needles, the pain was unbearable.

After a while, Tang Xu's hands no longer felt anything, as if they were completely numb, this is not a good sign, this does not mean that Tang Xu has adapted to the pain caused by thunder and lightning, but the nerves in his hands have been completely paralyzed and have lost their effect, so naturally they will not feel any pain. This is not what Tang Xu wants to see, what he wants is not only physical adaptation, but also mental ability to endure powerful thunder and lightning.

Tang Xu injected the true qi in his body into his hands, and the nerves on the surface of his hands were instantly full of activity, and the pain came again, and it was more painful than before, because the true qi not only made the nerves active, but also greatly increased their sensitivity several times, which meant that the pain was magnified several times.

Ten minutes later, Tang Xu's whole body was already wet with sweat, but what made Tang Xu excited was that he had been able to adapt to the sensation brought by the thunder and lightning. The next thing to do is to officially practice this first punch.

Driven by Tang Xu's true qi, the blue thunder and lightning slowly converged on the back of Tang Xu's hand, forming a boxing-like appearance. Now, what Tang Xu has is only the most ordinary thunderbolt, but the power is not comparable to ordinary martial arts. Tang Xu's right hand wearing fist gloves punched the surrounding stone wall, a puff of smoke and dust dissipated, and a half-meter-deep hole appeared on the stone wall, and the big hole was cracked, and even some had turned into smoke and dust, floating in the air. Tang Xu is still very satisfied with the power of this punch, now he only has the initial thunder and lightning, if Tang Xu is allowed to find other more powerful thunderbolts, then the power of this punch will be even greater. And the strongest thunderbolt in legend is a red thunderbolt called fire thunder. The power of thunder and lightning and the power of fire are the two most offensive attributes, and the fire and thunder are the perfect fusion of these two attributes, the power is by no means as simple as the sum of the two, but a qualitative change, the power is more than thousands of times stronger than this blue thunderbolt, but it is too early for Tang Xu to say, if he wants to master the power of this fire and thunder, the strength is impossible to complete without the tribulation period, and it also requires a great chance in it.

Tang Xu tried a few more times, and became more proficient in using this trick, of course, the pain was indispensable, but the gain was not small.

Now there is only one last book of exercises left, which is a book about the pace of the body, and it is also what Tang Xu needs the most now, last time he just took a few glances, and he gained something, now Tang Xu calms down and studies carefully, which will definitely make Tang Xu's body speed go to a higher level.

According to the description in "Wind Footwork", Tang Xu gathered his true qi on his legs to strengthen the strength and sensitivity of his legs. Tang Xu found that it seemed that all the exercises required the use of a large amount of true qi, fortunately, Tang Xu's body was baptized by thunder and lightning in the realm of nothingness, and he couldn't help but feel a lot stronger, and at the same time, it also widened the meridians in Tang Xu's body, making the true qi in his body rich, much stronger than that of ordinary immortal cultivators, with this unique advantage, Tang Xu was destined to cultivate much faster than others, and he could slightly alleviate the side effects of the Heavenly Rest Body.

With these favorable conditions, Tang Xu's cultivation is really twice the result with half the effort, after only practicing a few times, he has already memorized the whole set of steps in his mind, and the speed of using it is indeed a lot faster, but Tang Xu is not very proficient, and I believe that the speed can continue to improve after using it proficiently.

Tang Xu continued to practice the three exercises he had just mastered, and various explosions continued to come out of this cave, blue and white light continued to appear alternately, and the afterimage of his body moving rapidly continued to appear here. Tang Xu used the true qi in his body recklessly, not caring about what accidents would happen, Tang Xu was thinking now that he could find an opponent to compare and see what his strength had reached, but there was no one here, and this wish was destined to not come true.
