Lei Yin began to consume energy and materials, but fortunately, Lei Xingfeng had already disassembled most of the materials, so Lei Yin did not need him to put materials and energy at present, as long as he maintained a certain amount of hook stimulation.

Lei Xingfeng's attention was highly concentrated this time, he wanted to figure out what this prohibition was like, what it did, and what was the mechanism of the general formation, so he had almost no defense, and was preoccupied with the thunder seal, at this time, someone attacked, he would definitely be miserable, but fortunately, with the protection of the prohibition, he dared to pay so much attention.

After about a day, the prohibition formed a small piece, and there was a single prohibition growing, which gave Lei Xingfeng a wonderful feeling, as if these prohibition were like trees or weeds, watching them take root and sprout, and gradually grow into towering trees.

First, several prohibitions are connected to form a small compound prohibition, and then these small compound prohibitions continue to be connected to form a medium-sized compound prohibition, and the medium-sized compound prohibitions are connected to form a large compound prohibition.

Lei Xingfeng was extremely intoxicated, this kind of peculiar growth made his understanding of the prohibition greatly improved, it was really amazing, the prohibition actually grew out, from the simple prohibition at the beginning, to the complex prohibition, step by step.

If Lei Xingfeng didn't know the ban, it would be fine, but he was the great master of the ban, and his understanding of the ban was extremely profound, so no matter how complicated the ban was, since it was starting from the simplest, he could follow the growth of the ban and continue to understand it, and he would understand the most complex ban.

Looking at the prohibition of production is like learning the prohibition process, from the simplest to the most complex.

Ten days later, the entire collusion of the forbidden system grew, and there were about a thousand prohibitions, forming a composite forbidden array, and began to communicate with the thunder seal of Lei Xingfeng.

Then in Lei Xingfeng's double thunder seals, new prohibitions also began to grow, and the two reflected each other, forming a positive and negative prohibition.

Lei Xingfeng observed carefully, this is the second time to hook up the Thunder Seal, the first time he became a double Thunder Seal, Lei Xingfeng was actually a little ignorant, he was confused and successfully hooked up the Double Thunder Seal, as for what was the reason, what was the prohibition, there was almost no big feeling, and it was so successful.

And this time, Lei Xingfeng had an intuitive and understandable understanding, understood how to collude, and also had a deep understanding of the prohibition of collusion.

When his own thunder seal also grew a piece of prohibition, the two produced suction and began to approach quickly, at first the new thunder seal was still resisting, but the prohibition in the new thunder seal was erased by Lei Xingfeng more than ninety-nine percent, and he had no ability to resist at all.

Then Lei Xingfeng saw that the three thunder seals were combined, and the three thunder seals emitted dazzling silver rays at the same time, and the arc sound made a shocking sound and crackling sound.

Since Lei Yin and Lei Xingfeng are directly related, countless thunderbolts also emerge from Lei Xingfeng's body, which directly intersect with Lei Yin.

New thunder seals began to grow in large numbers New prohibitions, as if the small buds of plants were unearthed, and pieces of prohibitions began to emerge, and so did Lei Xingfeng's own thunder seals, and large pieces of prohibitions came out.

This process was quite long, but Lei Xingfeng didn't care at all, he waited very patiently.

The two affect each other, and the prohibition has also grown from simple to complex, a large amount of materials and energy are being consumed, but Lei Xingfeng does not need to be replenished at all, and the third thunder seal, just the dismantled materials, is countless, enough for the thunder seal to grow.

The materials dismantled by the million prohibitions are enough to grow another five or six hundred thousand prohibitions, which will inevitably destroy some materials, and the dismantled materials can be used by fifty or sixty percent, which can save Lei Xingfeng a lot of trouble.

Even if those dismantled materials are not good, they can actually be used, but Lei Xingfeng has relatively high requirements, and he basically discards these materials.

After a period of brewing, the three thunder seals have been combined, but this is the beginning, Lei Xingfeng calmly observed, looking at the prohibition in the third thunder seal, it began to spread to the second thunder seal, and then spread to the first, that is, his original seal.

Although this speed was very slow, it was quite smooth, and Lei Xingfeng found that the prohibition in his double seal grew faster, and soon surpassed the number of the third thunder seal.

And the spirit object in the third thunder seal also began to move, this is an instinctive action, because only the development of the thunder seal can make it strong, originally this spirit creature was already very weak, and it was all maintained by the big thunder crystal invested by Lei Xingfeng, but if it wants to grow, it must grow the entire thunder seal, and it has the hope of growth.

In half a year, the three thunder seals were finally completely fused, and at this time, Lei Xingfeng could cultivate, and once cultivated, the three thunder seals could grow at the same time.

Although the three Thunder Seals have been successfully fused, Lei Xingfeng still has to go through a long period of cultivation, that is, to let the prohibition in the Thunder Seal grow, otherwise the third Thunder Seal is an empty shell and will not work at all.

The first time he cultivated, Lei Xingfeng began to drive the Thunder Seal, and then Lei Xingfeng found that a large amount of energy was needed, although the third Thunder Seal also had a certain amount of energy, but the combination of the three Thunder Seals must be supported by external energy crystals.

Lei Xingfeng did not hesitate to start releasing the energy crystals he had collected, of course, this kind of Cheng Dù's cultivation did not use the top crystals like stalagmites, as long as he used the large energy blocks he had condensed before.

More than a dozen large energy blocks of this kind of foot length every day, Lei Xingfeng didn't care about it at first, but as time went by, tens of thousands of large energy crystals made him feel a little struggling, and this was only the fusion stage, and it was estimated that he would consume more energy when he cultivated in the future.

Fortunately, there are a large number of condensed energy crystals in the mirror realm, and the number is in the millions, this is because giant energy crystal mines have been found locally, and the energy condensed from these ores is where Lei Xingfeng's confidence lies, if it is maintained by stalagmite crystals, Lei Xingfeng himself is not sure.

Moreover, the stalagmite crystal is very high-grade, and when used in cultivation, the gains outweigh the losses.

Another year has passed, and the prohibitions in the three thunder seals have been densely packed, and in a year, the third thunder seal has grown 50,000 prohibitions, and the first and second thunder seals have grown more prohibitions, consuming 100,000 great energy crystals of Lei Xingfeng.

So much so that Lei Xingfeng felt that he couldn't afford to consume it, not only did he consume a lot of energy, but also consumed quite a lot of materials, if it weren't for the materials brought by the third thunder seal itself, it would be difficult for him to cultivate for a year in one go.

However, because of this, the three thunder seals are truly combined, that is to say, Lei Xingfeng has successfully reached the Cheng dù of the three-ring true body, this is still that he has not released the true body, once the real body is released, it will be completely finalized.

Taking Lei Yin into his body, Lei Xingfeng took out food and water, and ate slowly, generally speaking, he ate and drank once a month, and slept for a while, and until now, he also felt exhausted and too tired.

After eating, Lei Xingfeng fell asleep regardless of it, and this sleep was three days.

After waking up, Lei Xingfeng sat up, he rubbed his eyes, and then began to observe the thunder seal in his body, after three days of cultivation in his body, the prohibition in the thunder seal was still growing slowly.

At this time, it was time to use the best stalagmites, Lei Xingfeng took out a hundred top-grade stalagmites, and then released the thunder seal, he wanted to use the top-grade stalagmite crystals to consolidate the thunder seal.

The thunder seal flew out, and Lei Xingfeng stripped off the shell of the best stalagmite, which allowed the thunder seal to absorb it.

In the Thunder Seal, the three spirit creatures were all excited, and they also hoped to be able to absorb such a superb crystal, which would be of great benefit to their growth.

When the thunder seal swallowed a hundred top-grade crystals, the prohibition in the thunder seal began to grow wildly, and in an instant, dense prohibitions were generated, which was not the point, the focus was on the prohibitions that had grown up before, and began to grow towards a higher level of prohibition.

This is the reason why Lei Xingfeng put the best stalagmite crystals, he needs to push up the level of prohibition, and after a little calculation, the number of prohibitions in this seal, that is, in the thunder seal refined by Lei Xingfeng himself, has reached more than 300,000, and in the second thunder seal, the number of prohibitions has also reached more than 200,000.

The third thunder seal, the current number of prohibitions is far from enough, it needs to be cultivated slowly, only more than 50,000 prohibitions, and the number of the other two thunder seals, there is a big gap, but due to the best stalagmite crystals, the level of these 50,000 prohibitions has been forcibly pushed up, and the first two thunder seals can be cooperated.

This is the means of prohibiting the Great Grandmaster, he knows what kind of materials to put in when, and when to guide the prohibition in the seal, others rely on instinct to cultivate, and Lei Xingfeng can already control his own seal and cultivate according to the needs of the seal.

This point of Lei Xingfeng was already stronger than the ninety-nine percent cultivators.

This alone can throw other cultivators away by a large margin, and this progress is not trivial.

When the hundred stalagmite crystals were absorbed, and the three thunder seals were completely controlled, Lei Xingfeng tried to release his true body.

Rumble!

When the real body appeared, Lei Xingfeng was also startled, it was still more than 100 meters high, but Cheng Dù, who was condensed by his body, was greatly improved, whether it was the real body or the main body, it seemed that they had begun to change.

Countless currents were jumping, and the entire true body was dazzling silver, and at that moment, Lei Xingfeng knew in his heart that the strength of the three-ring true body was at least three times higher than that of the second-ring.
