The thunder bead turned into a huge thunder power, raging all the meridians in Lu Zifeng's body. A tingling sensation came from the young man's body, and even the meridians in his body spasmed under the power of this thunder.

Although the boy was suffering greatly at this time, the boy was not without gains. The strength of the muscles in his body was slowly growing at a snail-crawling pace.

The boy's forehead was furrowed, and his body was trembling slightly, and it was obvious that he was suffering greatly at this time.

A slight clicking sound continued to sound in the young man's body, which was the young man's use of the thunder power transformed by the thunder bead to break through the hidden meridians that he wanted to open up by cultivating the Nine Tribulations Thunder Dragon Body.

In less than half an hour, the young man had already broken more than fifty secret meridians in his body. It's just that after the boy broke more than fifty meridians, the time it took for the boy to open each secret meridian was growing.

Fifty meridians...... Sixty meridians...... Seventy meridians...... Eighty meridians......

When the boy had opened up the eighty meridians, it had already taken two hours.

It took another three hours for the young man to open up the ninety meridians.

There are still ten meridians left, and the young man can successfully cultivate the first layer of the Nine Tribulations Thunder Dragon Body, but this remaining ten meridians are the most difficult to get through.

If you want to get through these last ten meridians, I am afraid that the time it will take is several times longer than before.

Moreover, the power of the thunder transformed by the thunder bead, after opening up the ninety meridians, the power of the thunder has been consumed for the most part, and the remaining thunder power is obviously a little difficult to completely open up the last ten meridians.

However, difficulties must also be raised! The young man didn't want to drop the chain at this critical moment, and the young man's plan was to successfully cultivate the first layer of the Nine Tribulation Thunder Dragon Body in one go.

Over time, the ninety-first meridians, the ninety-second meridians, ...... The ninety-seventh meridian was also opened by the teenager one by one.

At this critical moment, the power of thunder is almost exhausted, can this power of thunder still ensure that he can open up these last three meridians? Lu Zifeng didn't know the bottom in his heart.

These last ten hidden meridians, and counting these last three meridians, are the most difficult to open.

The young man urged the few remaining thunder powers to impact the ninety-eighth meridian one by one, but this secret meridian, under the impact of the power of thunder, was unmoved, as if this little bit of power could not shake its seal at all.

The boy also knew that it was the most difficult to open up the last three meridians, so after the boy tried to impact the ninety-eighth secret meridian, the boy changed his mind, he was not in a hurry to open the last three meridians for a while, but first tried to accumulate strength, and when the accumulated power was large enough, he used the rebound power of this power to impact the last three meridians.

This idea of the teenager is obviously excellent.

Half an hour later, the boy's accumulated strength was strong enough.

The young man's spiritual sense took a deep breath in his mind, and then the young man's eyes suddenly sharpened, and the young man's spiritual sense shouted: "Break!"

So, the young man suddenly released the power that had been accumulated in this small half an hour, and with a bang, this huge and vast thunderous power, coupled with all the spiritual power of the young man, slammed towards the ninety-eighth meridian like a tidal wave.

In the past, when the boy hit the ninety-seventh meridian, the meridians did not move at all, but this time it was different from the previous time, the ninety-eighth meridian was being opened up at a rapid speed.

After two breaths, the ninety-eighth meridian was finally opened by the young man.

The strength accumulated in the young man's body continued unabated, and he rushed away like a monstrous wave against the ninety-ninth meridian.

With a bang, the ninety-ninth meridian couldn't last long at all under the impact of this powerful force, and was suddenly opened by the young man.

Up to now, only the hundredth meridian has not been opened by the young man. There is still this last meridian left, and the young man's copper thunder body can be regarded as a successful cultivation.

When he attacked the ninety-eighth meridian and the ninety-ninth meridian before, most of the strength that Lu Zifeng had accumulated before had already been consumed.

This hundredth meridian, its seal is particularly strong, twenty or thirty times stronger than the previous ninety-ninth meridian.

Lu Zifeng held a spirit of not admitting defeat in his heart, urging the power of thunder to slam the seal of the hundredth meridian fiercely.

However, Lu Zifeng's current impact on the hundredth meridian is not as strong as the previous impact on the ninety-eighth meridian and the ninety-ninth meridian, and this impact, the seal of the hundredth meridian does not move at all.

After about ten minutes, the power of the thunder was completely consumed, but the seal of the hundredth meridian was still as solid as a rock, no matter how Lu Zifeng urged the spiritual power impact, it was difficult to advance an inch.

In the end, the spiritual power in the young man's body was completely exhausted, but no matter what the hundredth meridian was, Lu Zifeng couldn't get through it now.

Lu Zifeng also knew that this thing could not be forced, and now he had successfully cultivated the copper thunder body by opening up the last meridian. However, the power of thunder contained in this thunder bead was so great that the boy was also taken aback. After all, when the boy was opening up these hundreds of meridians, the boy had a deep understanding of the difficulties of opening up these hundreds of hidden meridians.

Now, with the power of the thunder bead, the young man has opened up the ninety-nine secret meridians, and this kind of harvest is already very great.

As for not opening the last meridian, although Lu Zifeng regretted it, he was not discouraged. Cultivation can't be achieved overnight, if this supreme spiritual martial arts is so easy to cultivate, then it is not worthy of the title of supreme spiritual martial arts.

"Hoo ......"

The young man slowly opened his eyes and exhaled a breath of turbidity, only then did he stand up, clenched his fists, and felt the surging power of the muscle cells in his body, and a smile appeared on the young man's face.

The boy could feel that his physical strength had changed drastically now compared to before. His current physical strength is comparable to the strength of a cultivator in the late stage of the Spirit Martial Realm, and the young man guessed that as long as he successfully cultivated the Copper Thunder Body, then he could compete with the Xuandan Realm just by relying on his physical strength.

The young man knew that in the Tianyang Kingdom, there were still four major families, and the strength of the younger generation they cultivated was bound to be much stronger than his own. In order to be able to have a little more confidence in the seed selection competition, the goal of the teenager is to successfully cultivate the copper thunder body, as long as he successfully cultivates the copper thunder body, then he also has the strength to fight with them.

Otherwise, just by relying on his spiritual power cultivation at the end of the Spirit Martial Realm, the young man would not consider himself to be their opponent.

During this period of time, the young man has been putting the direction of his cultivation on spiritual power cultivation, and the young man's current spiritual power cultivation has been unable to keep up with his spiritual power cultivation.

If possible, the teenager also wants to improve his spiritual strength within a month before the seed selection contest starts. In this case, the teenager has an extra hole card, which gives the teenager a better chance of winning the seeding tournament.

The boy never forgot his mission, which was to travel to the Far North Ice Sheet to find his mother. Now, entering one of the five major sects is the first step for the boy to find his mother.

The boy knew that his background was too low, and with his current strength and background, if he wanted to find his mother, the boy didn't even have the qualifications to enter the Arctic Ice Field, so how could he get his mother back.

As long as he joins the five major sects, further improves his strength, and becomes the mainstay of his sect, then he is qualified to go to the Arctic Ice Plain to find his mother.

My mother's background is quite strong, and if I don't have enough strength to find my mother, I'm afraid that I will be killed by my mother's people before I see my mother.

The boy didn't have a good impression of his mother's people, and if it weren't for them, how could he have been separated from his mother for so many years. Although his father didn't say it, Lu Zifeng knew that his father was thinking about his mother every day, but his father didn't want to worry about him, so his father didn't tell him.

Therefore, if you want to find your mother back, then you have to have a strong strength, so strong that they tremble and don't even dare to say a word of objection. Lu Zifeng used the five major sects as a stepping stone for his strength to improve, and found his mother through this stepping stone.

This is what Lu Zifeng is planning in his heart at this time.

For now, let's succeed in cultivating the Bronze Thunder Body first.

The meal should be eaten in one bite, and the road should be walked step by step.

Don't rush anything, otherwise it will backfire.

After Lu Zifeng withdrew from the cultivation state, the young man looked around the cave, and at this time, soft sunlight came from the entrance of the cave, which was blocked by huge rocks.

The boy covered his eyes with his hands, squinting slightly, and it took a while for him to get used to it.

Unexpectedly, as soon as I practiced like this, I had already passed a whole night, and time passed so fast.

After there was movement on Lu Zifeng's side, Qiao'er was the first to wake up while leaning on a rock, she looked at Lu Zifeng who stood up with her eyes open, and said in surprise: "Lu Zifeng, have you finished cultivating?"

"Hmm. Lu Zifeng nodded.

"How?"

"There is still one last meridian left, and the cultivation of the copper thunder body has been successful. Hearing this, Lu Zifeng said with a little regret.

"In this case, don't worry, I can use the power of the Abundance Gold Auction House to help you find some treasures that contain the power of strong thunder, and ensure that you will successfully cultivate the Bronze Thunder Body before you participate in the Imperial City's Seed Selection Competition. ”

Li Xuelin also knew that Lu Zifeng wanted to successfully cultivate the Bronze Thunder Body before the seed selection competition in the Imperial City began, so in this way, his chances of being good in the competition would be much greater, so she spoke out to comfort Lu Zifeng.

"Well, well, I owe you a favor. ”

Lu Zifeng also knows that now is not the time to be hypocritical, he will write down this favor first, and when he has the right opportunity, he will inevitably repay her.

Hearing this, Li Xuelin's cold pretty face finally showed a smile, such a charming and moving Li Xuelin is really beautiful.
