Just when Zhao Qingtian and the others left Lingming Demon Valley, Lu Kun was staying in a crypt, sitting cross-legged with his eyes closed, with a hideous expression on his face, looking extremely painful. Pen, fun, and www.biquge.info

From time to time, a trace of lightning appeared outside the body, making a few crackling sounds, and the robes on his body had been turned into ashes by these few rays of lightning, revealing Lu Kun's strong body.

The muscles on his right arm twisted irregularly, and there was a pale white circle on the outside of his upper arm on the surface of his skin, and there were three colors of light circulating in the circle.

Each point of light is about the size of a fingernail, and as it circles in a circle, it is still moving closer to the middle, but there seems to be a great resistance in the middle of the circle, making it impossible for the three points of light to merge.

Cold sweat broke out on Lu Kun's face, and he only heard him snort coldly.

Suddenly, tiny bolts of lightning appeared outside his torso, and they bounced on their skin with a slight popping sound.

These tiny lightning bolts made Lu Kun's body scorch, and they were immediately controlled, and they quickly converged towards Lu Kun's right arm.

The three points of light on the big arm seemed to be greatly stimulated, and they accelerated and rotated.

The color of the light point in the rapid rotation also changed, turning purple, and then a dazzling purple light flashed on his right arm, and Lu Kun fell straight to the ground.

His charred body twitched slightly, and it took a while for him to recover, and then he slowly got up, holding his right arm across his body.

"How is it possible? failed?" Lu Kun looked at the three purple light spots on his right arm, revealing a look of extreme disappointment.

"I've been studying it for so long, and this thunder mark has finally taken shape into a purple lightning-like mark, and now there are only three purple dots, which means that this mark has failed to condense!" Lu Kun muttered.

He felt the empty thunder attribute mana in his body, and said in extreme frustration: "I didn't expect that the condensation of thunder attribute mana for so long would be in vain. ”

"That's not right!"

"If the Shangqing Imperial Thunder True Technique says that it fails, it won't form any mark at all, but what are the three purple dots on my arm?" Lu Kun muttered strangely as he looked at the purple dots of light on his arm that did not show the slightest sign of dissipation.

Then he thought about it for a while, then sat cross-legged, took out two spirit stones of fire wood in his left and right hands, and began to cultivate.

After Lu Kun's cultivation was lowered, he cultivated the mana of Yuanshui Refining Body Decision, which had a great conflict with liquid mana, so every time he cultivated, he first cultivated the liquid mana.

The amount of liquid mana was very small, and Lu Kun quickly completed it, and then he replaced the spirit stone with a water-attribute spirit stone and began to cultivate water-attribute muscle mana.

A few hours passed in a flash.

"Huh?"

After the cultivation was over, feeling the change in mana, Lu Kun couldn't help but open his eyes, and said to himself with some doubts: "My cultivation has broken through?"

At this time, Lu Kun's mana fluctuations had reached the level of the twelfth layer of qi refining.

"Could it be the reason for the thunder attribute mana? Or is it that the portrayal of the thunder seal has allowed me to break through the bottleneck?"

Lu Kun suddenly remembered that Nie Wufeng had told him that if he recultivated after being devoured by the Yuan Devouring Technique, his cultivation speed would be faster.

During this time, he did not take the initiative to refine his physical body, but every time he transformed the thunder attribute mana, it was counted as a small refining body, not to mention that when he transformed the thunder seal, the muscles of his whole body were tempered by the lightning that came out of the thunder attribute mana.

"It's good that my cultivation has broken through, otherwise my hard work in transforming thunder attribute mana in the past year will really be in vain. ”

Lu Kun recalled the scene where he had just portrayed the Thunder Seal, and said to himself: "In the end, I used all the thunder attribute mana to portray the Thunder Seal, and in the end I was still a little powerless. ”

"Could it be that my thunder attribute mana is too small to depict a complete thunder seal?"

As he spoke, Lu Kun took out the "Shangqing Imperial Thunder True Technique" again, flipped it to the Lei Yin, and re-read the content that he had studied for nearly a year.

In this year's time, the first thing Lu Kun did was to transform the thunder attribute mana step by step, and sure enough, as he expected, in the first two months, the speed of the transformation of the thunder attribute mana was okay, reaching one-third of his mana reserves.

Then the speed slowed down, because the transformation of each thunder attribute mana required nearly two-thirds of the water attribute mana and all the liquid mana in the bones.

Next, it took Lu Kun more than four months to transform one-third of the thunder attribute mana, and the last one-third took Lu Kun half a year.

In addition to transforming the thunder attribute mana, he has also been consulting the depiction method of the thunder seal, which is very strange, whenever Lu Kun encounters a bottleneck, as long as his hidden thunder spirit root appears, some problems will be solved.

He not only comprehended how the thunder seal was depicted, but also comprehended the method of portraying the thunder seal for physical cultivation.

"Shangqing Yulei True Recipe" is to be depicted in the dantian, because the place where the aura is converted into mana and the mana is stored are in the dantian.

And the place where the body cultivates and transforms mana and stores mana is in the muscles of the body, so the thunder seal should be engraved on the body, but the human body has more than 600 skeletal muscles, so it can't depict more than 600 thunder seals.

If each Thunder Seal required the whole body's thunder attribute mana carving, Lu Kun's remaining longevity of two hundred years would be completely insufficient.

Later, Lu Kun studied it and found that the size of the thunder mark was related to its radiation range, and finally concluded that only six positions on the body needed to be carved to cover all the ranges of the body's muscles.

These positions are the arms, legs, chest, and back, and the further back you go, the bigger the shape that the Thunder Seal needs to carve.

The thunder mark of the arm, the range can radiate the entire arm, Lu Kun plans to depict the thunder mark on his right arm first, if he succeeds, he will be able to directly cultivate the thunder attribute mana through the muscles of his right arm, so that the thunder refining body can be regarded as a beginner.

The same principle as the spirit control magic weapon, Lu Kun only needs one muscle to have mana transformation, and under the drive of the muscle, the muscle mana of the whole body can be transferred.

Lu Kun took advantage of the appearance of Lei Linggen today, and began to carve the Thunder Mark on his right arm, but he didn't expect that this confident portrayal would directly end in failure.

"I understand, it's not that my method is wrong, it's that my thunder attribute mana is not enough. Lu Kun watched "Shangqing Imperial Thunder True Recipe" for a while, and the lightning flashed in his mind, and he instantly understood the reason for his failure.

"The larger the thunder seal, the wider the radiation range, then the more mana such a thunder seal consumes, and the mana of the eleventh layer level of Qi refining before before is not enough to depict the arm thunder seal. ”

"And the thunder marks on the legs, front chest and back need more mana. ”

"I'm now refining the twelfth layer of qi, and after transforming the full thunder attribute mana, I should be able to depict the thunder mark on my right arm. ”

Since Lu Kun figured it out, he made up his mind and continued to transform the thunder attribute mana.

However, his heart moved, and he placed the place where the thunder attribute mana was transformed under the unfinished thunder seal.

As the three points of light transformed into Lu Kun, the purple light above became brighter and brighter.

Only half an hour later, Lu Kun opened his eyes and said with a look of surprise: "I have transformed a thunder attribute mana so quickly, it seems that this unformed thunder seal can speed up the transformation of thunder attribute mana!"
