When Ning Wangshu tried to take the initiative to mobilize the invisible sword qi to penetrate into his bones and impact his cultivation, those invisible sword qi that lingered in his internal organs immediately swelled slightly. Pen & Fun & Pavilion www.biquge.info

The five internal organs that had been tempered to the peak were stirred by those invisible sword qi, and there was a 'bang' sound like the tide crashing on the shore.

Ning Wangshu felt the situation in his body, and his mind always remained calm, and he did not stir up any waves because of this.

Under his mobilization, a trace of invisible sword qi seeped into the bones little by little, and the invisible sword qi in the internal organs became more and more intense, Ning Wangshu gradually felt that some kind of shackles were gradually loosening, and it might not take much time to completely break through this fragile shackle in one fell swoop!

As time passed little by little, about thirty or forty minutes later, Ning Wangshu was shocked.

Immediately afterward, the invisible sword qi that lingered and filled in his internal organs suddenly receded like a tide, and spontaneously surged to every bone around Ning Wangshu's body, slowly penetrating deep into the bones......

Feeling the changes in his body, Ning Wangshu secretly breathed a sigh of relief.

At this moment, his cultivation in the inner strength stage was completely over. The next step is to start refining the marrow!

The process of refining the marrow of the Extreme Dao Sword Code was obviously not so pleasant either, as those sharp formless sword qi penetrated into the bones in large quantities and began to refine the bone marrow, Ning Wangshu immediately felt bursts of unspeakable pain coming from the inside of every bone in his body.

So much so that his body couldn't help but twitch and tremble slightly.

"Well, it hurts......"

Ning Wangshu hissed in his heart, and secretly gritted his teeth to endure the sharp pain of those invisible sword qi refining marrows, and this painful feeling exceeded the previous stages of Yi Tendon, Bone Forging, and Internal Strength.

Ning Wangshu gritted his teeth and persisted for less than twenty minutes, but finally couldn't bear it anymore and stopped.

When he stopped, Ning Wangshu was already soaked with sweat, and the beads of sweat on his forehead gathered into two streams and dripped down Ning Wangshu's cheeks.

Ning Wangshu walked out of the sword formation with some difficulty, and immediately supported his knees with his hands on the side, bent over and gasped for breath.

"I didn't expect that this process of refining the marrow was even more painful than the previous bone forging and inner strength. This Extreme Dao Sword Code is really not something that ordinary people can afford. There is no willpower and endurance beyond ordinary people, and if you want to cultivate this Extreme Dao Sword Codex, I am afraid that you will not even be able to pass the threshold of foundation building!"

Ning Wangshu said secretly.

What he thought was not bad at all, this Extreme Dao Sword Code was indeed not something that ordinary people could cultivate, not only paying attention to qualifications and physique, but also requiring very harsh will and patience.

After secretly complaining in his heart, Ning Wangshu could only sigh in the end that this Extreme Dao Sword Book was worthy of being an immortal exercise, not only the exercise itself was against the sky, but the tempering that he had to endure to cultivate this exercise was also at the level of going against the sky.

However, there is an old saying that only when you suffer hardship can you become a superior person. Without tempering, how can you become a sword warrior?"

"Therefore, no matter how painful it is to cultivate this Extreme Dao Sword Codex, I must persist in it!"

Ning Wangshu's expression suddenly became extremely firm.

After sighing, thinking that he had finally successfully broken through to the stage of refining the marrow, Ning Wangshu couldn't help but feel a little happy and relaxed.

Now that it is late September, he still has two months to improve his cultivation as much as possible, and prepare for the Yinhai City High School Student Martial Arts Competition to be held in late November.

In the past two months, with the Extreme Dao Sword Codex, as well as the previous technique, and with the abundant money in his hand to purchase elixirs or pills to assist in the refining of the marrow, Ning Wangshu was full of confidence that he would be able to cultivate at least to the later stage of the refining of the marrow, and it was not impossible to even reach the peak of the refining of the essence.

His current cultivation speed can indeed only be described as a thousand miles a day, coming in by leaps and bounds.

When he returned home, he comfortably took a medicated bath, and after some simple breakfast, Ning Wangshu rushed to school with his schoolbag.

Today's martial arts class is in the morning. After Ning Wangshu arrived at the school, he put his schoolbag in the cultural classroom, and then immediately rushed to the martial arts classroom.

As the class bell rang, Jiang Ying soon walked into the classroom.

Unless there is a new martial arts class to teach all students, most of the time is given to students to practice martial arts on their own.

The teacher is more likely to give some guidance and guidance to each person in private according to their situation.

After all, in martial arts practice, everyone's situation is different, and it is difficult to generalize, let alone have a unified 'answer'.

After Jiang Ying came to the classroom, she gave a few words of instruction, and encouraged everyone a few words, and then let the twenty students in the first class of the third year of high school practice on their own.

Subsequently, Jiang Ying's eyes quickly noticed Ning Wangshu's body.

Ning Wangshu was the student she paid the most attention to and valued, and when she saw Ning Wangshu start to cultivate the Heavenly Wind Sword Technique, Jiang Ying immediately noticed the subtle changes in Ning Wangshu's momentum.

Ning Wangshu's momentum when he used the Heavenly Wind Sword Technique at this moment was obviously much stronger than yesterday, and his sword moves were also more powerful and powerful.

Jiang Ying could naturally see at a glance that Ning Wangshu's Heavenly Wind Sword Technique had not entered the realm obviously, his Heavenly Wind Sword Technique had only broken through to the Furnace Fire Perfection level for a few days, how could he not see any significant progress for a day?

The only explanation is obviously Ning Wangshu's cultivation!

"Could it be...... His cultivation has successfully broken through to the stage of refining the marrow?"

Jiang Ying immediately thought of this, and couldn't help but feel a little happy in her heart, watching Ning Wangshu gradually unleash the Tianfeng Sword Technique one move at a time, the color of appreciation in her eyes became more and more intense.

After a while, when Ning Wangshu was about to finish practicing the Heavenly Wind Sword Technique, Jiang Ying walked towards Ning Wangshu.

After Ning Wangshu put away his sword and stood still, Jiang Ying couldn't help but ask, "Ning Wangshu, has your cultivation broken through to the stage of refining the marrow?"

Suddenly hearing Jiang Ying's inquiry, Ning Wangshu hurriedly turned around, and then showed a smile to Jiang Ying, did not hide it, and nodded lightly in response: "Yes." Teacher, you are really as wise as a torch, I just broke through when I was practicing in the morning, and you immediately noticed it when you met him!"

Hearing Ning Wangshu's compliment, Jiang Ying smiled faintly and couldn't help but appreciate: "Okay! The teacher really didn't misunderstand you, and you successfully broke through to the stage of refining the marrow so quickly." ”

"It seems that when you take the college entrance examination next year, your cultivation should be nine out of ten if you want to break through to the Qi refining period! At that time, you are fully qualified to choose any of the eight major martial arts academies, and it is no longer them who choose you!"
