After Lu Zifeng got the Lei Yuanjing of the Xuandan Realm Thundering Beast given to him by Li Fengjin, the young man immediately entered a state of retreat.

There is not much time left until the seeding tournament starts, and if you don't improve your strength as soon as possible, you will not be able to win the seeding tournament at all.

In order to be able to win in this seeding competition, Lu Zifeng must quickly improve his strength.

Because the young man's spiritual power cultivation was too strong some time ago, the young man needed a period of time to stabilize his foundation, otherwise in order to rush to improve his strength, his foundation would be unstable, and the impact on his future cultivation would be considerable.

It is precisely for this reason that the boy focuses on improving his physical strength and spiritual power cultivation, and Lei Yuanjing is the item necessary for the boy to improve his physical strength.

As for improving one's spiritual power cultivation, then wait for one's Bronze Thunder Body cultivation to succeed. As the saying goes, you have to eat one bite at a time, and you have to go step by step on the road.

Lu Zifeng believed that such a small Thunder Source Crystal was enough to help him successfully cultivate the Copper Thunder Body.

With the help of Li Fengjin, Li Fengjin found a secret room for the teenager to retreat and practice.

Lu Zifeng sat cross-legged in the Li family's secret room, and the young man took out the Lei Yuanjing that Li Fengjin gave to him from the storage ring.

In the young man's hand, a silver-white crystal was spinning, and from time to time there was a crackling sound flickering around the crystal.

After taking out the Lei Yuanjing, the young man could feel that the power of thunder in the entire secret room suddenly became extremely strong, and even the young man's skin felt a tingling feeling. It was unimaginable that such a white crystal contained all the cultivation of a Thundering Beast in the Xuandan Realm.

"Hoo ......"

Lu Zifeng took a deep breath, his eyes no longer hesitated, and swallowed the Lei Yuanjing in his hand.

With a grunt, Lei Yuanjing was swallowed by the young man. After Lei Yuanjing entered the young man's body, Lei Yuanjing quickly turned into an extremely large and terrifying thunder force. This huge thunder force raged everywhere in the boy's meridians, making the meridians in the boy's body become spasms.

However, after this thunder power entered his body, the young man could feel that a small stream of thunder power was absorbed by the muscle cells in his body, and the muscle cells that absorbed the power of thunder were slowly increasing.

Sensing the benefits of the thunder power contained in the thunder source crystal to himself, and the pain brought to him by the power of thunder, the young man had long since ignored it. The young man's face was happy, and then the young man no longer hesitated, controlling the thunder power in his body, and quickly operating according to the cultivation method of the Nine Tribulations Thunder Dragon Body.

When the young man controlled the thunder power in his body to run to the last meridian, he was blocked by a solid bottleneck, and the huge thunder power could no longer enter.

The young man knew that this bottleneck was the last meridian barrier for his cultivation of the Nine Tribulations Thunder Dragon Body, as long as he opened up this meridian, the Copper Thunder Body would be considered a successful cultivation.

The young man's face became extremely solemn, and the young man knew that the thunder power in his body that had been transformed into a thunder source crystal was the most powerful, and this was the best time for him to break through this last bottleneck.

If this thunder power is continued to be absorbed by the muscle cells in the body, the power of this thunder power will be weakened, and it will be a little difficult to break through the bottleneck of this last meridian, so what should be done now is to break through the bottleneck of this last meridian in one go.

After making up his mind in his heart, the young man did not rush to control the thunder power in his body to impact the bottleneck for a while, but instead controlled the huge thunder power in his body and retreated a long distance.

After the boy thought that this distance was enough, the power of the thunder in the boy's body instantly accelerated, and he quickly rushed towards the bottleneck of this last meridian. With the blessing of sufficient speed, it increases the power of thunder to hit the bottleneck.

Bang!

A slight muffled sound sounded, but this muffled sound was like a shocking noise in the young man's body, and the bottleneck of this last meridian shook violently under the impact of this extremely powerful thunderous force.

It's just that it seems that this thunderous power is still lacking, and it hasn't achieved much results. The strength of the bottleneck of this last meridian exceeded the boy's expectations.

Sure enough, it is worthy of being a top-grade spiritual martial arts level refining martial arts, and even the copper thunder body of the first layer is so difficult, so the thunder dragon body of the second layer and the nine tribulation thunder dragon body of the third layer are even more difficult.

However, it is precisely because of its great difficulty in cultivation that it will have a correspondingly great power.

It is unimaginable that after Lu Zifeng successfully cultivated the Nine Tribulation Thunder Dragon Body, how strong the young man's physical strength would be.

The first time he hit the bottleneck of the last meridian, although it ended in failure, but the young man was not discouraged in the slightest, if he succeeded in cultivating the copper thunder body so easily, this martial art was not worthy of being the best spiritual martial arts.

The second time he hit the bottleneck, the boy first controlled the thunder power in his body and retreated a distance, but this time, the boy controlled the thunder power to retreat twice as far as the first time.

As a result, the young man controlled the power of the thunder for the second time, and fiercely impacted the bottleneck of the last meridian. This time, the speed of hitting the bottleneck was even more rapid than the first impact, like a shocking wave, hitting the bottleneck fiercely with an irresistible momentum.

Bang!

An even more violent collision sound sounded in the boy's body. Under this impact, the boy felt a sharp pain, and frowned against the sharp pain.

This extremely powerful impact, the bottleneck that had previously appeared quite solid, was violently shaken, and a tiny crack quietly appeared on the barrier after this impact.

Seeing this, the young man was overjoyed, and then the young man controlled the power of thunder in his body without stopping, and fiercely impacted the bottleneck of the last meridian.

Enduring the pain of impacting the meridian barrier, under the ruthlessness of the young man, the rock-solid barrier could not resist the attack of the young man, and after the young man hit more than ten times, he finally slammed and completely shattered.

The power of thunder no longer has the resistance of the meridian barriers, just like the stream flowing into the sea and finding its own belonging, wandering in the meridians of the young man's inscription at will.

After the young man broke through the last meridian barrier of this cultivation copper thunder body, a huge momentum suddenly erupted from the young man's body, shattering the young man's shirt, revealing the young man's considerable muscles.

Although there are no exaggerated muscles, the streamlined muscle lines make people understand the power of this small body without hesitation.

The color of the skin on the boy's upper body was relatively white and tender, but now the color of the boy's upper body is a healthy and strong bronze, which looks like it is coated with a layer of brass, revealing a sense of solidity.

After breaking through the barrier of the last meridian, the young man's body still had a considerable amount of thunder power.

The young man did not become complacent after breaking through the barrier of the last meridian, the young man controlled this huge thunder power in his body, and operated in the direction of the meridians of the cultivation copper thunder body.

After the boy ran this thunder power, a silver line slowly appeared on the boy's upper body, but this line was quite light and short at the beginning, and as the muscle cells in the boy's body absorbed the power of thunder increased, this silver line slowly became clear, and continued to extend.

Looking at the direction of the silver line, it seems to be wrapping around the boy's upper body. It was precisely because of this that this silver line became clearer and clearer as the boy absorbed more thunder power.

This kind of change is not noticed by the teenager at all.

If the young man saw this silver line, the young man would definitely be quite surprised, because this silver line was the thunder pattern of cultivating the Nine Tribulations Thunder Dragon Body, such a small thunder pattern, the power contained in it was so huge that the young man was surprised.

As long as the boy successfully cultivates the nine thunder patterns, then in every move, the boy has the power to turn the world upside down, but the current boy is still quite far from this realm, because at this time, the boy's copper thunder body is just getting started, and only when the three thunder patterns are condensed, can it be regarded as the completion of the copper thunder body.

After the copper thunder body, there are two levels of the thunder dragon body and the nine tribulation thunder dragon body, and the young man still has a long way to go if he wants to successfully cultivate this superb spiritual martial arts.

With the passage of time, this huge thunder power in the boy's body was gradually absorbed by the muscle cells in the boy's body. The boy could feel that the strength of his body was rapidly improving.

About two hours later, the boy finally absorbed the thunder power in his body, and at this time, on the upper body of the young man**, a silver-white thunder pattern surrounded the young man.

It is such a small thunder pattern, which contains the power of thunder that has been cultivated by the Thunder Beast of the Xuandan Realm all his life, so it can be seen how powerful the power contained in such a thunder pattern is.

The boy slowly opened his eyes, and a bolt of lightning seemed to flash through the boy's eyes, and even the turbid breath that the boy spit out contained a huge thunderbolt power, crackling.

The young man slowly stood up, feeling the huge force surging in his body, and a satisfied smile appeared on the young man's face.

Myself, I finally succeeded in cultivating the Copper Thunder Body!

As the saying goes, cultivation doesn't know time. The young man didn't know how long he had been cultivating, so he stretched his waist and walked out of the secret room.

The dazzling sunlight shone on the young man's body, and the young man took a breath of fresh air outside, although he had not been cultivating for a long time, but the young man had a feeling of being in a different world.

The young man walked towards his residence, walking and walking, the young man suddenly saw Li Xuelin, and was about to step forward to talk to the girl, but he didn't expect a burst of anger on the girl's face, as if he didn't see the existence of the young man, and hurriedly walked over.

Li Xuelin ignored herself, the young man was not angry, the focus of the young man was not this, but the angry Li Xuelin, he had never seen Li Xuelin look like this.

Li family, is this something big going on?
