Gradually, a main technique came to mind, called "Heavenly Demon Transformation". This magic skill is one of the most authentic magic skills in ancient times. There is no way to cultivate on weekdays, and it can only be learned through a generation of big demon emperors and the inheritance of the emperor demon seed. This exercise is complicated and vast, thanks to the fact that Lei Dong has been inherited by the emperor demon seed, this exercise only needs to be carefully figured out, and you can get a glimpse of the skin.

However, if you want to completely digest it and cultivate it to perfection, I'm afraid it won't be so easy. First, "Heavenly Demon Change" is extremely complicated, and second, Lei Dong is limited by his own cultivation, and he can't give full play to the full power of magic skills.

But even so, Lei Dong vaguely felt that this "Heavenly Demon Change" should be more powerful than some of the top ** of the Yin Demon Sect.

In addition to the main technique of "Heavenly Demon Change", there are also a series of supporting spells. These require Lei Dong to slowly comprehend the magic tricks after carefully practicing the Heavenly Demon Transformation. Different from some spells of the Yin Sha Sect, even if there is no matching **, it can be cast, but the power is different. However, some of the spells in the Heavenly Demon Transformation can only be cast one by one after practicing the main exercises.

In this barren mountain and cave, a place where spiritual energy is scarce, Lei Dong decided to stay for a few months first, and carefully understand the technique of Heavenly Demon Transformation in his mind. Perhaps it was for fear that when the inheritor's strength was insufficient, he would forcibly cultivate the changes in the future. At this time, the emperor demon seed was transmitted to Lei Dong's mind, and there was only one change. Only after cultivating this kind of change can you get the subsequent changes from the Emperor Demon Seed again.

Time seems to fly by very quickly.

Lei Dong meditates at night refining qi, relying on a medium-grade spirit stone and a small five-element pill worth a middle spirit, even if there is no spiritual energy here, Lei Dong's cultivation speed is not slow. Of course, the consumption rate of spirit stones is much faster.

And during the day, he will comprehend the mystery of the Heavenly Demon Transformation.

Just a month later.

Lei Dong somewhat understood the first change of the Heavenly Demon Change, which was unparalleled in the world. As the name suggests, this is a state of mind, a state of mind in heaven and on earth. Only with this kind of mentality, with infinite arrogance in the chest, can we truly comprehend this heavy realm and master the first change.

Xuanyin True Qi is one of the most authentic exercises in the Demon Dao. It is also extremely suitable to use Xuanyin True Qi to urge the Heavenly Demon Transformation.

Lei Dong pondered with his heart the artistic conception of the unparalleled state of mind in the world that the previous Demon Emperor had left in his mind through the Emperor Demon Seed. Every time he realized the depths, a sense of pride in Lei Dong's heart was slowly stimulated. In his eyes, he was calm and proud. Just holding his hands behind his back and standing there quietly, there is a kind of momentum that dominates the world and looks at the world.

In this month, it was extremely difficult for Lei Dong to achieve this state of mind, even if it was just a simple simulation of this state of mind. In essence, although Lei Dong has arrogance in his chest, he has arrogance in his back. But these were deeply buried in his strong cautious attitude. Only when it really angered him to the deepest part of his self-esteem would that arrogant air be revealed.

For example, between the Heavenly Demons, Lei Dong couldn't control himself, and he couldn't grovel to her.

Fortunately, the previous Demon Emperor instilled in those who had no experience helped a lot, and Lei Dong's comprehension was also excellent, so he really couldn't appreciate the world's unparalleled state of mind. Thinking more about the Heavenly Demons is of no use.

During the day for a whole month, Lei Dong spent his time in a state of mind that constantly simulated and realized the unparalleled in the world. From the beginning it was difficult and inaccessible. In the end, Lei Dong only had to be calm for a while, and he could initially enter the world's unparalleled state of mind.

I saw that the Xuanyin True Qi in the thunderous body couldn't help but circulate, driving the Heavenly Demon to change the exercises. Gradually, the speed of the heartbeat became faster and faster, and the thunderous skin became a little rosy. Immediately after that, the heartbeat became faster and heavier. In the thunderous expression, it gradually became painful from bland, and his breathing became heavy and short.

But this pain seems to be only for a moment. The blood seemed to be gradually starting to boil. In the soul, there is a feeling of relaxation and immortality. It made him tremble all over his body. As the blood became hotter and hotter, Lei Dong only felt that his chest was getting bigger and bigger, and he couldn't help but open his mouth and roar.

Echoes. The splinters of the cliff wall of this wilderness cave shook and fell.

It was as if a dull breath accumulated in the chest was swept away at this time. There is an incomparably happy and hearty feeling.

Lei Dong clenched his fists, only to feel that his whole body was full of endless strength. There was a feeling in my heart that I could destroy everything if I wanted to, and the blood was circulating rapidly throughout my body, and my skin was hazy with a layer of blue light. The thunderbolt just kicked with his feet, and the whole person shot straight away like a cannonball.

Boom~ hit the roof of the cave hard, and the stones cracked, but Lei Dong was not injured at all. Floating under the roof of the cave, I only feel happy in my heart, and the endless power needs to be vented.

At this time, if Lei Dong could see his face and eyes, he could see a smile on his face, and the smile was full of bloodlust. In his eyes, there seemed to be a kind of arrogance in his eyes, but it was mixed with a thick anger and murderous intent.

"Smack!"

Lei Dong kicked heavily on the top of the cave, and his body rushed straight down. But he fought with incredible movements, and his feet stepped on the ground again. With a bang, the stone ground was torn apart, and at the same time, the thunder rushed straight out of the wild hole, turned a corner, and went straight into the sky.

Its speed is at least twice as fast as when Thunder Movement casts a ghost escape. Of course, it can't be compared with the ghost. After casting the Heavenly Demon Transformation, his entire person's mentality, behavior, and battle intent were completely different. Lei Dong only felt that there was infinite ** in his chest to vent, and there were countless powers in his body that were inexhaustible.

A boulder half a foot wide was smashed into pieces under a single punch. A towering ancient tree surrounded by several people was hit by his shoulder and elbow, the fibers cracked, and the giant tree collapsed. A waterfall that is a few feet wide is slapped away with one palm, but it is temporarily stagnant.

Such an attack and killing power is far from being something that a first-level monk in the foundation building period can do. Thunder, destroying everything he saw. Until a passing colorful tiger was grabbed by him, torn in two, and poured tiger blood in a big gulp. The Xuanyin True Qi in the body seemed to have been completely burned, and the green light around the body was rapidly fading. His eyes and face also became exhausted at this moment.

It seems that with just a stick of incense, all the power of Lei Dong has been burned, and even a lot of overdraft. Sitting on the ground, the thunder of the recovery of his mood was thunderous, and he gasped for breath. The Heavenly Demon Transformation burned not only the Xuanyin True Qi, but also the Thunderous Physical Strength. At this moment, he is gone, and he is gone, and he is not even interested in refining qi and meditating. The bones all over his body seemed to have been torn apart, and the pain made him almost collapse. All power has dried up. The Heavenly Demon Transformation is like a demon girl who demands excessively, squeezing the thunder cleanly.

Of course, Lei Dong also knew that this would definitely not work. Endure the illusion that the meridians of the whole body burst and the bones turned into powder. Sitting down, he reluctantly swallowed a small Five Elements Pill, held a medium-grade spirit stone in his hand, and began to refine his qi and meditate.

After a few hours, Lei Dong stood up again full of energy, and there was a faint burst of joy in his eyes. This meditation seems to have improved a lot, and the effect of meditation is no less than that of four or five days of meditation on weekdays.

Cultivators all know that if the true qi is really consumed excessively, and then refining the qi and meditating, the effect will often be better. But that's about it. The problem is that if you want to really consume all your true qi, you have to spend a lot of effort and time not mentioning it. It is also an endless torture of people's spirits.

In order to speed up the cultivation speed a little bit, it takes a lot of time and mental torture, but very few people will do this. Of course, some sects that claim to be righteous do just that. For example, Kongoji Temple. The practitioners of Kongo Temple are very harsh on themselves in the world. But I have to admit that they are very powerful, especially in terms of willpower, other top sects are not comparable to them.

However, this time, the effect of Lei Dong is obviously much greater than the effect of consuming true qi by itself. At the end of this day, there are several days of kung fu cultivation effect.

Lei Dong's heart moved, he could not use this way. First, it can speed up the cultivation speed, and second, it will not delay the cultivation of the Heavenly Demon Kung Fu. However, out of prudence, Lei Dong still checked whether there was anything wrong with himself first. After checking and checking, I only felt that the bones and muscles, as well as the meridians, were still a little sore, and there was nothing serious.

In fact, Lei Dong doesn't even know about himself. On weekdays, whether the monk fights or cultivates spells on his own, the power in his body will be consumed. But the problem is that although the true qi seems to be mostly concentrated in the dantian. In reality, however, it is scattered in every corner of the body, in every cell. The so-called depletion of true qi actually means that even the true qi in the dantian has not been completely exhausted.

It is also because of this that when some monks and people are desperate, it is clear that the true qi has been exhausted. But it can still have a final explosion, or even explode after the outbreak, and the true qi that is used in the whole body is stored. It's not that when the dantian is really empty, it can't use any tricks, especially at the most critical juncture of life, it often bursts out with more power. These are the reserve forces that have been slowly accumulated during the cultivation of the daily water for a long time.

But if you want to squeeze out the reserve power for no reason, it is extremely difficult, extremely painful, and requires a very masochistic way to barely achieve it.

But the Heavenly Demon Transformation is different, this belongs to one of the strongest exercises of the Demon Dao in the ancient period. Once cast, it burns all the power that can be burned. to achieve the goal of increasing strength in a short period of time and being extremely powerful. It's like, all the time, it's like fighting for your life with people.
