After all the teams were put together and sorted out, Lei Dong handed over the affairs of the team to King Kong, and according to the arrangement of the settled Zen master, what he had to do now was to calm down and realize his realm in this feudal war tomb.

In order to cultivate with more peace of mind, Lei Dong chose to leave temporarily, the current team, with the powerful fierce King Kong sitting in the formation, and the famous Phoenix in the north to assist, Lei Dong has been able to put his mind at ease, and he and King Kong can use the Demon Alliance Realm to connect, once there is any situation, he can also come to help immediately.

Lei Dong returned to the Miasma Mountain, on the Miasma Mountain, there are the most corpse thunders, among these corpse thunders, Lei Dong is easier to enter the realm of heart and thunder, which is extremely conducive to Lei Dong's cultivation.

Because there are more corpse thunders at night, Lei Dong has changed his work and rest time, often sleeping during the day and practicing at night.

That night, he stood in the abyss of miasma more than ten feet high, and released the thunder and lightning in his body outward little by little, just like the battle he had with Amaso that time.

Soon after, a three-dimensional matrix of thunder and lightning formed around him, and he felt the thunder and lightning, and through this thunder and lightning, his senses became more wide.

In the past, he was about 1.8 meters tall, but now the thunder and lightning that spread outward are part of his body, and he seems to have a height of more than ten zhang and a width of dozens of zhang through the perception of these thunderbolts.

"Heart thunder is in the field, suitable for the condensation of thunder and lightning, and the outside of the body can be tempered by mutual strikes of thunder, producing small thunder changes and then entering the body, until it hits the sixth order [Ability Realm]!" The idea in the thunder swallowing technique began to sound in Lei Dong's heart again.

Lei Dong was happy in his heart, he was a fifth-order fifth-order last time, and he was still far away from the sixth-order ability realm, and now according to the hints in the thunder swallowing technique, he could actually cultivate like this until he hit the sixth-order ability realm, which was a dream for him.

However, how can the lightning outside the body be tempered by mutual strikes?

Lei Dong closed his eyes, silently felt the thunder and lightning outside his body, the branches and branches reached dozens of zhang, although these thunderbolts are very dense, but they have a natural isolation from each other, they are irrelevant to each other, and they can't collide together at all, and if they can't collide with each other, they can't complete the mutual impact tempering, and the thunder of the method of improving the thunder power can't be implemented.

"This is a thunder with rules, and if you want to collide with each other, you must transform these thunders with rules into irregular thunder!" Lei thought to himself.

After thinking about this, Lei Dong opened his eyes violently and shouted: "Burst!"

When he called out the word 'explosion', his consciousness also controlled the thunder and lightning outside his body, resulting in a small explosion.

When there is no explosion, thunder and lightning have rules, and once they explode, thunder and lightning lose their rules, and countless thunderbolts begin to intertwine explosions outside the thunderous body, and the forces collide with each other and merge with each other, which is the mutual tempering of thunder and lightning.

After this wave of explosions, Lei Dong continued to use Lei Nian to urge the thunder and lightning in his body to explode again, and every time he exploded, Lei Dong could feel the madness, throbbing, and mutation of the thunder and lightning outside his body.

This is an adventure, the feeling of urging the thunder and lightning to explode is extremely uncomfortable, usually, the thunder only releases the thunder and lightning to kill the enemy, and never thought of collecting the thunder and lightning released from the body, but this time is different, after the thunder and lightning exploded outside his body, he still has to endure not to let these thunder power drain, because he also has to recycle them into his own body, otherwise it will be equivalent to doing useless work.

Every thunderbolt caused a churn in Lei Dong's stomach, and several times, Lei Dong was so disgusted that he almost vomited, but he endured it silently.

"Come on, brother believes that as long as you have experienced wind and rain, you will definitely be able to see a rainbow!" Lei Dong said in his heart, waiting for the rainbow after his efforts.

After ten waves of thunder explosions, the thunderbolt will release the thunder and lightning outside the body, and inhale it into his body one by one.

At this time, he suddenly felt that he seemed to be much lighter, this lightness, not the lightness of the **, but the lightness of the thunder force, his whole body bloodline is the system of storing thunder power, in the past, the thunder power was not refined enough, so his bloodline was slightly crowded, and now after all kinds of thunder power has been tempered, the volume has been significantly reduced, and the bloodline seems empty.

Just when he felt this strangeness in his body, his pores were violently opened by the impact of a strange force, and then a strange yuan force was actually integrated into his bloodline, and the originally empty bloodline, after adding these yuan forces, it was crowded again, but it was still much more empty than at the beginning.

"Lei Yuan is condensed, the blood veins are empty, and the Yuan Force is sucked into the blood veins with the thunder pressure and assimilated into thunder, this is the phenomenon of thunder melting!" The voice in the thunder swallowing technique began to sound again.

Although the Yuan Force between Heaven and Earth is ubiquitous, the concentration is not large, and the Lei Yuan in the Yuan Force is even rarer.

Lei Dong has also tried to absorb the surrounding thunder force into the body before, but that kind of absorption, the scope is very small, the effect is very small, not like now, so many thunder elements poured in at once, this is because the thunder at this moment has also converted other yuan forces in the surrounding environment into thunder yuan, which is the thunder melting phenomenon mentioned by the thunder swallowing technique.

As more and more thunder power poured in, Lei Dong felt a burst of comfort in his body, although the process of forging thunder was painful, but the process of melting thunder was extremely pleasant.

No cultivator thinks that there is more yuan power in his body, and Lei Dong felt the benefits of forging thunder, so he naturally continued to forge while the iron was hot.

Those thunderbolts that have been tempered don't need to be exercised anymore, and in the following time, thunderbolts will be changed to other thunderbolts.

The thunder and lightning in Lei Dong's body have a huge base, and what Lei Dong can develop at this moment is only the tip of the iceberg, and at his speed, he may not be able to change it in dozens of days.

In the next half month, Lei Dong has been repeating such a thing.

Half a month later, the Xuan Yuan in Lei Dong's body actually had a trace of fluctuation, in the past, Xuan Yuan always had to be Lei Dong after thinking about it, and then he would turn into a phantom and stand behind him, this kind of autonomous fluctuation had never happened before.

That is, not long after Xuan Yuan seemed to fluctuate, the information in the Thunder Swallowing Recipe was transmitted to Lei Dong's brain again:

"Xuanyuan has changed by half, and the melting thunder has entered the stage of selfization, after this stage, the Xuanyuan Thunder Pool will become your Thunder Pool, and the Xuanyuan will turn into a part of your Thunder Pool. ”

No wonder Xuan Yuan will fluctuate, it turns out that after the thunder power of Xuan Yuan has been trained by Lei Dong, it has mutated and become Lei Dong's own thunder force, although Xuan Yuan has no emotion, but he still has a little instinct, and when he finds himself about to become someone else, it produces this fluctuation.

After Lei Dong knew this information, he realized in his heart that although Xuanyuan's thunder power was incomparable, it had always had Xuanyuan's character, and it was all owned by Xuanyuan, although it was controlled by him, it was not his thunder and lightning, but after condensation, and the mutated thunder and lightning was his thunder and lightning.

But he has some sentimentality, Xuan Yuan, is his most respected power, in his heart, Xuan Yuan is a respectable uncle, he didn't expect that his own growth will make the imprint of an uncle he respects in his heart fade more and more, and then disappear, until it becomes his own imprint.

But...... The back waves push the front waves, everything has to be thought of in a positive way, although Xuan Yuan is worth nostalgia, after all, he is already the Thunder King in the past, and he can't stop because of his nostalgia for Xuan Yuan.

"Xuan Yuan, I will inherit your will, even if my thunder power has been reborn in the future, I will still call this thunder power [Xuan Yuan], I will inherit your momentum of killing the sky, and I will also carry forward that momentum, I will take you and kill the way to heaven!"

Lei said in his heart, when he said this, he thought of the scene of Xuanyuan killing the sky 90,000 zhang that day, Xuanyuan wanted to kill outside the sky, but Xuanyuan stopped in the sky, but he thundered and could, he was a Skywalker, he believed in himself, he would definitely be able to kill outside the sky!

Lei Dong was still working hard to temper the thunder and lightning in his body as always, and with the tempering of the thunder and lightning, his rank improvement speed was unprecedentedly accelerated, the fifth order sixth level, the fifth order seventh level, the fifth order eighth level, and the fifth order ninth level...... By the twenty-fifth day, his rank had already rushed to the fifth and ninth levels, and he had come to the boundary line of the sixth order.

By the thirtieth day, the thunder power that could run in Lei Dong's body was already twice the size of when he entered the Sealed Frontier War Grave, and he could try to impact the sixth order.

The swastika-shaped dantian is constantly running in his body, and due to the addition of thunder power, at this moment, wisps of thunder veins will emerge from his swastika dantian from time to time.

Lei Dong's mind was clear, he had never felt that the Yuan Force in his body was so abundant, in order to break through the shackles of the dantian wall in one fell swoop, he transferred the thunder power at his disposal from the blood vessels to the dantian.

With the influx of thunder power, the star sand in his dantian began to evolve into thunder light, burning in the boundless starry sky, endlessly dazzling.

The thunder power that can be introduced into the dantian is limited, and after the dantian is saturated, Lei Dong can no longer transfer the thunder power to the dantian, and at this time, Lei Dong took another risk.

"Boom!"

He silently recited a burst word in his heart, and then detonated the thunder and lightning in the dantian.

The Yuan Force in the other people's dantian can't explode, but because of the thunder power in his dantian, it can explode.

It was as if it was the primordial point before the universe was born, and an entire universe exploded in the void, and in the midst of the thunder and lightning, his fifth-order dantian wall finally couldn't bear it, and first squeezed it inward, and then it was blown outward by the crazy thunder and lightning.

Endless Star Sand Thunder Gravel, like a wild horse, rushing into a more open space, here is the sixth-order dantian, here is a broader world, with the thunder of this heaven and earth, it will create more wonderful deeds than before!
