Lu Zifeng took Li Xuelin and Qiao'er and her two daughters from the Yunfeng Wasteland to the Imperial City of Tianyang Kingdom.

Since there was still a month before the start of the seed selection competition, it would be enough for them to rush to the Tianyang Kingdom Imperial City for more than a week, so Lu Zifeng and the three of them were not in a hurry, and they were in a hurry along the way.

Lu Zifeng did not relax his cultivation. Before he entered the Yunfeng Wasteland, his spiritual power cultivation was only in the early stage of the Spirit Martial Realm, and then he refined the Xuandan in Yun Feiyang's predecessor's body, and his spiritual power cultivation was promoted to two levels in a row, and he suddenly had the strength of the late stage of the Spirit Martial Realm.

In the battle for the summit of the Yunfeng Wasteland Altar, he successively defeated Fairy Mei, Xu Qingyan, and Fang Pengfei, although he did not reach the summit because Fang Pengfei was possessed by the Phantom Devil, but he had bathed in the baptism power of the altar twice before, and his spiritual power cultivation had reached the peak state of the late stage of the Lingwu Realm.

Later, in order to save Xu Qingyan, he sacrificed himself to block the Turbidity Demon Blood Spear, and because of this, he was seriously injured and dying. In order to save him, Yun Feiyu's predecessors mobilized a lot of baptism power to heal Lu Zifeng's injuries. Under the bath of a large amount of baptism power, when Lu Zifeng's injuries were completely healed, his spiritual power cultivation was also promoted to the end of the Lingwu Realm.

In this short period of more than a month, the young man has been promoted from the strength of the early stage of the Lingwu Realm to the end of the Lingwu Realm, and the promotion speed of such a demon is really incredible.

However, the teenager can have such a rapid promotion speed, and that is also the teenager's desperate achievement. The boy almost died during this trip to the Yunfeng Wasteland. The strength of a teenager was obtained by risking his life.

In this world, there is no strength that comes from nothing, only if you pay the corresponding price, you will return accordingly.

Lu Zifeng also knew that in the near future, it would be impossible for him to be promoted in his spiritual power cultivation. Therefore, he focused all his energy on the Nine Tribulation Thunder Dragon Body obtained from Yun Feiyu's hands.

This top-grade spiritual martial arts-level thunder system body refining martial arts, although Lu Zifeng only had a glimpse of it, but he also had a slight understanding of the subtleties and profundities.

In the hands of Yun Feiyu's seniors, he was able to rely on the Nine Tribulations Thunder Dragon Body to smash a majestic mountain that was a hundred feet high. Such a terrifying strange power, I am afraid that the strength of the Xuandan Realm will be encountered, and it will have to be avoided.

Lu Zifeng was not arrogant enough that he could cultivate to the level of Yun Feiyu's predecessor at once, but he was not arrogant either, he planned to cultivate the third thunder pattern before the seed selection competition.

Nine Tribulation Thunder Dragon Body, it is divided into three layers, every three thunder patterns are divided into one level, the condensation of three thunder patterns is the copper thunder body, the condensation of six thunder patterns is the thunder dragon body, and the condensation of nine thunder patterns is the Nine Tribulation Thunder Dragon Body.

As long as the cultivation of the copper thunder body is complete, then Lu Zifeng, with this simple physical strength, is basically an invincible existence in the Lingwu Realm. It's just that the Nine Tribulations Thunder Dragon Body is not such a simple martial art, and if you want to cultivate the Copper Thunder Body, it is impossible to succeed without more than half a year.

Lu Zifeng obviously thought of this, but he had no way to speed up the speed of cultivating the Copper Thunder Body, unless he had some treasure containing a large amount of thunder power.

The power of thunder?

Lu Zifeng frowned, the treasure containing the power of thunder, as if he had such a treasure on his body, but he forgot which treasure it was.

By the way, in the three martial arts of the Xu family, the Sun family, and the Lei family, he helped the Xu family get three places to enter the thunder pool, and at the bottom of the thunder pool, he met the thunder spirit python, and after killing the thunder spirit python, he obtained a thunder bead.

This thunder bead is not only the essence of the Thunder Spirit Python, but also the essence of the power of thunder contained in the Thunder Water Pool. This Thunder Spirit Python absorbed a large amount of thunder power from the Thunder Water Pool, otherwise it would not have condensed its form.

With this thunder bead, Lu Zifeng has confidence that he can cultivate the first two thunder patterns, and as for the third thunder pattern, it depends on how much thunder power is contained in the thunder bead.

Lu Zifeng didn't have much confidence to cultivate the Bronze Thunder Body with this Thunder Bead, after all, the Nine Tribulations Thunder Dragon Body was not a low-level body refining martial art, but a rather subtle and advanced body refining martial art. If it could really cultivate the Copper Thunder Body so easily, it wouldn't be worthy of being a top-grade spiritual martial art.

Either way, you won't know until you try it.

Towards evening, Lu Zifeng and the others found a relatively safe place in the forest and settled down.

In the forest, there were quite a lot of wild boars and pheasants and other prey, so Lu Zifeng hunted a few pheasants as dinner for the three of them.

After dinner, Lu Zifeng found a place to do it, and quietly began to study the Nine Tribulation Thunder Dragon Body.

After about two or three hours, Lu Zifeng withdrew from the state of concentration. At this time, the young man had a tired face.

If you want to fully study and understand the Nine Tribulation Thunder Dragon Body, with Lu Zifeng's current strength, it is obviously a little bit worse. However, he also had some impressions of the cultivation method and meridian operation method of that part of the copper thunder body. In this part of the copper thunder body, Lu Zifeng has already begun to comprehend, but if he wants to fully comprehend the cultivation method of the copper thunder body, it is obvious that it will take a while.

Lu Zifeng didn't rush to fully comprehend the copper thunder body, after all, it was a superb spiritual martial arts. This level of martial arts, Lu Zifeng is still in contact with it for the first time, and it is nothing to spend some more time cultivating.

Although the difficulty of the cultivation of the Nine Tribulation Thunder Dragon Body was beyond the boy's expectations, the boy was extremely excited. The Nine Tribulations Thunder Dragon Body of this difficulty did not make the boy return from the difficulty, but aroused the interest of the young man. This kind of difficulty makes the teenager feel challenging. If the Nine Tribulation Thunder Dragon Body didn't have this difficulty, it would disappoint the young man.

In the following days, the young man, Li Xuelin and Qiao'er, all traveled during the day and practiced at night.

After more than a week of enlightenment, Lu Zifeng finally became fully enlightened. The cultivation method of the copper thunder body and the operation mode of the meridians have been memorized by the young man one by one. Everything is ready, only the east wind is owed, and the rest is just a young man to start cultivating.

On the second day after Lu Zifeng fully comprehended the cultivation method of the Copper Thunder Body, the young man decided to start the Nine Tribulations Thunder Dragon Body on this day.

In the evening of this day, the young man found a mountain range where the spirit beasts lived, and after driving out the spirit beasts living in it by brutal means, he found a boulder to seal the cave.

This time, it was not as good as the previous days of contemplating the Nine Tribulations Thunder Dragon Body. This time, the boy was preparing to cultivate the Nine Tribulations Thunder Dragon Body, and during the cultivation process, he couldn't be disturbed by others, otherwise he would be disturbed by others at all, which would cause him to go mad. Lu Zifeng couldn't bear this kind of result, so he had to start cultivating the first layer of the Nine Tribulation Thunder Dragon Body in the safest way.

Among them, there is no room for error.

Li Xuelin and Qiao'er also knew that tonight was the time when the young man was preparing to cultivate the Nine Tribulations Thunder Dragon Body, so the two daughters took on the important task of protecting Lu Zifeng.

However, in this kind of deep mountain and old forest, Lu Zifeng and the three of them did not meet a few cultivators along the way, and now that the three of them are in the cave here, in such a secret place, naturally no one will disturb Lu Zifeng.

Lu Zifeng was not in a hurry to start cultivating the Copper Thunder Body at the beginning, but slowly entered a state of concentration.

After about half an hour, the young man slowly opened his eyes, and now he was full of energy, and he had adjusted his condition to the best state.

"Hoo ......"

Lu Zifeng took a deep breath and slowly calmed his mood. The storage ring on his finger flashed, a flash of thunder, and a thunder bead appeared in the boy's hand.

As soon as this thunder bead appeared, the entire cave was filled with a rich thunder power.

When Li Xuelin and Qiao'er were breathing, they only felt a tingling in their bodies. This is the reason why this thunderous power permeates the entire cave.

The surprised eyes of the two women were on the thunder bead in Lu Zifeng's hand, when had they ever seen a young man get such a thunder bead containing the power of thunder. Qiao'er was a little puzzled, because she felt a familiar feeling from the thunder bead in Lu Zifeng's hand.

This familiar feeling, as if she had felt it somewhere, just didn't remember it for a while.

Since she couldn't figure it out, Qiao'er didn't think much about it, she relaxed, and a pair of beautiful eyes were placed on Lu Zifeng's body. She also wants to see how far the teenager can go.

Lu Zifeng's eyes were firmly fixed on the thunder bead in his hand, and after a blink of an eye, the young man no longer hesitated, and swallowed the thunder bead in his hand.

As soon as the thunder bead entered the boy's body, the thunder bead instantly turned into a huge thunder force. This thunderous power was enough to seriously injure any cultivator at the end of the Spirit Martial Realm.

As soon as this thunderous power entered the young man's body, it raged wildly, violently impacting the fragile meridians in the young man's body.

A sharp pain came from all the meridians, and the young man clenched his teeth, frowned, and moved his hands to form a rather strange seal. With the formation of the seal method, the power of thunder raging in the boy's body was under the traction of the boy, and it operated in a strange trajectory.

In order to cultivate the copper thunder body, the young man must at least open up hundreds of secret meridians in his body. However, now that the young man has such a huge thunder power, it must not be too difficult to open up hundreds of secret meridians.

Under the impact of this huge and vast thunder power, one after another the hidden meridians were broken through by the young man. Moreover, where this thunder power passed, the muscle cells in that place became extremely active, as if absorbing this huge thunder power like a demon.

The young man could feel that under the tempering of this thunderous power, his physical strength was getting stronger little by little.

This time, will the young man be able to rely on the power of this thunder bead to cultivate the bronze thunder body?
