Lei Xingfeng no longer thought that the thunder-based materials released by a cultivator with a second-ring true body were not weaker than the two who left just now, and this time it was really developed.

He found that there were at least seventeen or eighteen kinds of thunder materials, and he had never even seen them, although he had never seen these materials, but he knew that they were definitely what he needed.

When a cultivator looks for a material, it is actually the material that the seal needs, and once the seal is generated, it will automatically select the material, and the seal can be distinguished from what material is needed and what material is not.

Just like plants need nutrients, what can be absorbed will be automatically absorbed, and what cannot be absorbed is useless no matter how much you put it.

Therefore, the materials in the cultivation world are almost all identified by seals, and after a long time, after someone has sorted them out, the cultivators will know what kind of materials to collect.

Putting away the materials released by the three of them, Lei Xingfeng was very satisfied, he now understood that it was really difficult to collect all the materials for promotion just by digging by himself, and it was the best way to trade with others.

It's just that it's not easy to meet a cultivator, and it's almost difficult to communicate with the other party when they meet, and unless they can win the opponent, maybe the transaction can go smoothly at that time.

After getting this batch of materials, Lei Xingfeng knew that there was no problem at all when he advanced to the Fourth Ring True Body, and he was in a good mood and said: "This pit is yours, and how to distribute it is your own business." ”

After Lei Xingfeng finished speaking, he walked away.

The three cultivators looked at each other, the price paid was too small, but what they got was too much, the three of them released their true bodies, jumped down the pit and dug quickly, they didn't dare to hesitate at all, who knows if there will be another high-level cultivator.

Once a high-level cultivator comes, the three of them will not be able to keep this pit, they can only dig it out quickly and put it into the wheel storage space, as long as they are unwilling, even if they kill them, it is useless.

Digging hard, the three of them all fought, this is a very good quality energy crystal mine, the best of which has been dug up by Lei Xingfeng, and there are still some of the best and boutiques left, the three of them are the first time to encounter this kind of good mine, and they are digging crazy.

Lei Xingfeng flew forward for a distance, and scanned the earth in the air, his eyes were filled with silver, and he soon saw the glow of several mining points.

He gradually discovered a characteristic, where the ore points are gathered, although there are many mines, but there are few high-quality mines, and where the mines are scarce, this mine must not be wrong, there are many high-quality mines, and there are very few ordinary mines.

This time he got a large amount of thunder materials, Lei Xingfeng no longer had the heart to continue digging, just like earning money in his previous life, and suddenly getting a large sum, the first thing he thought of was to spend money, not to continue to earn money, and now he has the same idea.

After turning from the Mirror Realm, Lei Xingfeng returned to the place where he had cultivated before, where there was still a forbidden protection.

Lei Xingfeng sat down, released the Thunder Seal, and began to check the prohibitions in the Thunder Seal, and the battle with the two Four-Ring cultivators made a lot of prohibitions in the Thunder Seal, and he began to remove those useless prohibitions.

In fact, the third ring to the fourth ring is a hurdle, but this hurdle does not exist for Lei Xingfeng, because he has a ready-made thunder seal, as long as the superposition is successful, the contact is prohibited, and there are enough materials and energy, it is a matter of course.

If you want to generate a new Thunder Seal, it will be more troublesome, not only a matter of materials and energy, but also a matter of the formation of prohibitions.

Lei Xingfeng included most of the thunder materials in the thunder seal, and then began to cultivate.

At this moment, the prohibitions in the three Thunder Seals were all growing wildly, because with enough materials and a large number of energy crystals, the speed of this growth was terrifying.

The prohibition generated in the battle is growing up rapidly, and it is quickly connected into pieces, this kind of growth consumes materials and energy the most, especially energy, and it is consumed extremely quickly, but fortunately, Lei Xingfeng's collection of energy is really very much, and it can be consumed completely.

had already met the requirements for promotion, and after this time of cultivation, Lei Xingfeng knew in his heart that he could be promoted.

took out a thunder mark that had already been processed, Lei Xingfeng held it in his hand, he drove his own thunder seal, and began to contact the thunder mark in his hand, that is, to use his own thunder mark to influence the thunder mark in his hand and let it grow out of the prohibition.

With the passage of time, Lei Xingfeng's seal grew into a prohibition, and in the thunder seal in his hand, there were also prohibitions gradually generated, and the thunder mark in Lei Xingfeng's hand gradually began to tremble, which was attracted by this seal and tried to fly.

Lei Xingfeng knew that this was far from enough, and he continued to urge the ban and let the ban grow little by little.

The thunder seal in his hand has been suspended, and under the effect of the prohibition, it is getting closer to the seal hanging above his head.

During this time, Lei Xingfeng can't interfere with the two, once the combination fails, this seal is not a big problem, but the newly taken out Lei Yin is finished, and it is impossible to use it again, so Lei Xingfeng is very careful.

The speed of energy consumption doubled, Lei Xingfeng was secretly surprised, if he hadn't obtained an extremely large number of energy crystals, he would really not be able to support it, and now it would be a trivial matter.

You must know that during this time, Lei Xingfeng is a nest of many energy crystals, a nest of mines, the number of crystals is unimaginable, and these energy crystals, dug out, can be used, there is no need to purify, it is very pure, the energy contained in the crystals is quite rich.

Relying on the huge energy reserves and the prepared thunder materials, Lei Xingfeng's promotion was very smooth, without any flaws or flaws.

When the thunder mark in his hand was close to the main body thunder seal, a large number of thunderbolts shot out from the body thunder seal, directly hitting the approaching thunder seal, and in an instant, the silver-white dazzling eyes flashed, and Lei Xingfeng couldn't help but squint his eyes.

Lei Xingfeng looked at the thunder seal that was about to fuse, and his heart beat sharply, if he succeeded, he would become a cultivator of the Four Rings True Body.

When the two thunder seals approached, the thunder and lightning from this seal made the prohibition in the other thunder seal grow wildly, as if the positive and negative poles attracted, and the prohibition of both was growing rapidly.

When the prohibition grows to a certain extent, the two begin to slowly approach.

Lei Xingfeng was engrossed, staring at the prohibition in the two thunder seals, this is a mutual force, and now relying on the thunder and lightning communication, the prohibition on both sides gradually tends to be the same, and the two thunder seals are getting closer and closer.

Lei Xingfeng's whole body suddenly shook, and the two seals were finally superimposed together, and in an instant, the four thunder seals combined, and then fell into Lei Xingfeng's body, and in an instant, Lei Xingfeng began to tremble violently.

The whole body was bursting with electric arcs, and Lei Xingfeng felt as if he had fallen into the flames, and his whole body was burning.

This is Lei Xingfeng's first taste, Lei Yin's transformation of his body, this time it was very sudden, which caught Lei Xingfeng a little off guard, however, his toughness is excellent, and he also has strong willpower, even if it is unexpected, he gritted his teeth and persisted.

There seemed to be countless ants crawling in the bone marrow, and the skin was in severe pain, just like the feeling of boiling water on the body of an ordinary person and burning his whole body.

That kind of pain, if it were an ordinary person, would be over, and it would definitely hurt people to death.

Lei Xingfeng's teeth gritted and rattled, his eyes opened in an instant, he felt that his eyeballs were about to fly out, his whole body trembled violently, and he couldn't even make a sound.

The pain was not long, about a few minutes, but Lei Xingfeng felt that it had passed for a few years, it was too terrible, when the pain receded like a tide, Lei Xingfeng poured out a lot of sweat all over his body, he gasped frantically, and his mouth made a meaningless hehe.

According to Lei Xingfeng's thoughts, he was grilled alive, and just when Lei Xingfeng was glad that it had passed, a sharp pain came again, and in an instant, Lei Xingfeng wanted to scold, but the severe pain made him unable to say a word.

This time the time was a little shorter, and Lei Xingfeng could see that his arm was scorched black, and he could also see a trace of electric arc beating on his skin.

The second pain made Lei Xingfeng a little dizzy, but he knew in his heart that he must not faint to death at this time, and he turned his attention to Lei Yin.

The four thunder seals are completely combined, and from time to time a large amount of electricity is released, the pain in the body is caused by the thunder and lightning, you must know that his body has long adapted to the current, but this time it is different, the thunder and lightning contained in the four thunder seals are too huge, even his body is difficult to digest and absorb, so it has formed an effect similar to body transformation.

With the release of electric thunder again and again, Lei Xingfeng experienced torment again and again, and with the passage of time, he began to gradually adapt, after all, it is the body of the thunder attribute, adapting to the energy of thunder and lightning, which is different, if people with other attributes are hit by this kind of thunder and lightning, they will basically turn into ashes.

After surviving the impact of seventeen thunderbolts, from the first few minutes, to the last few seconds, Lei Xingfeng finally survived, when the thunder and lightning in the thunder seal subsided, he had reached the point of exhaustion, and his whole body was weak, and he didn't have time to return to the mirror realm, he fell asleep.

I slept for seven or eight days.

When Lei Xingfeng opened his eyes, he suddenly felt completely different, his whole body was pregnant with explosive power, and the feeling was extremely refreshing.

When he got up, Lei Xingfeng found that the skin on his body was all scorched black, as if there was an extra thick shell, and when he reached out and wiped it, a layer of skin a few millimeters thick fell off, and Lei Xingfeng felt nauseous when he saw it, and he immediately flew out.

Soon he found a river and plunged into it.

After taking off a layer of skin all over his body and cleaning it for a long time, Lei Xingfeng found that his skin was extremely white and tender, and his eyelids jumped when he saw it, this kind of skin really made him very unaccustomed to it, it was simply white and dazzling.

After washing, Lei Xingfeng changed into a new set of clothes, and then flashed back to the Mirror Realm.

Coming out of the courtyard, Lei Xingfeng was used to walking into the wooden shed.

There were a lot of people sitting in the wooden shed, and Wuyang and the others were there, looking at Lei Xingfeng with strange eyes one by one.

Lei Xingfeng said: "What's the matter? What are you doing looking at me?"
