In the Demon Suppression Division, the Iron-Cutting Sword Technique is perfected

The sudden rain caused by the dragon came and went quickly.

When Gu Cheng left the martial arts arena and rushed to the armory of the Demon Suppression Division under the rain, the sky had already cleared.

The Spirit Bird Venerable had already greeted the guards of the armory.

After Gu Cheng revealed his identity and handed over the armory secret order, he directly obtained the handwritten copy of the second volume of "Blue Dragon Hundred Refinements" without much effort.

As for the other two armory secret orders he won, he had not yet decided what martial arts to exchange for them, so he kept them for the time being.

Back to the No. 17 courtyard of Wuzi.

Cao Jianxin was practicing sword in the yard. Seeing his sleepless appearance, it was obvious that he had a new understanding of his swordsmanship.

Gu Cheng did not disturb him and quietly returned to his hut.

Putting the second volume of "Blue Dragon Hundred Refinements" on the table, looking at this thick secret book of martial arts, he was quite excited.

After a series of twists and turns and efforts, he finally got the technique he had been dreaming about.

"Compared with "Crimson Palace Heavenly Thunder Induction", the content of the second volume of "Blue Dragon Hundred Refining" is obviously much less.

I still have the experience of practicing the first volume, so I think it will be much easier to practice, right?"

Gu Cheng thought so in his heart.

But when he confidently opened the first page and began to read this precious technique carefully, the smile on his face disappeared.

Damn!

This technique is not short in content, it is just written very concisely.

When practicing "Crimson Palace Heavenly Thunder Induction" before, at least Xu Nianxue's own attention and experience were there, so it was easy to read.

This second volume of "Blue Dragon Hundred Refining" has nothing, it's just like asking a foreigner to read classical Chinese.

It's just a heavenly book!

"Hiss - I suddenly have a bad feeling..."

Gu Cheng rubbed his swollen eyebrows and read the secret book in his hand.

Then there was a prompt on the system panel.

[Break the Ordinary (Rare) · Blue Dragon Hundred Refinement: Not yet entered]

[Remaining Lifespan: 4,013 Years]

Gu Cheng glanced at his remaining lifespan and felt relieved.

It took one lifespan to refine the three demon cores of the water demons in the Break the Ordinary Realm, but now there are still more than 4,000 years left.

It shouldn't be a problem to upgrade this precious skill to the maximum level, right?

With this thought in mind.

Gu Cheng took out a few pots of nebula flowers from the storage bag and placed them on the wooden table.

Smelling the rich fragrance of the flowers, he couldn't help but relax a little.

Then he poured his vast lifespan into "Blue Dragon Hundred Refinement".

[Year 1: You open this thick martial arts secret book and start practicing the second volume of Canglong Bailian.

After years of practice and study, you have already had your own unique understanding of the martial arts.

But when studying this profound martial arts technique, you are still like a child who has just entered school and have no idea how to do it. ]

[Year 7: After a long time under the shroud of the fragrance of the nebula flower, you suddenly have a flash of inspiration.

You start practicing according to your sudden understanding, and spend three years, but there is no progress at all.

You don't believe in evil and think that great force can make miracles happen. You start to force the practice until you go crazy and almost explode and die! ]

...

[Year 87: After a long period of recuperation, your body finally recovered, and the strength of your meridians in your body has slightly increased.

At this time, your brain is filled with endless confusion.

You begin to doubt your original intention, thinking that there are so many techniques that can break the ordinary realm in the arsenal of the Demon Suppression Division, why do you have to hang yourself on a rare technique? 】

"Sure enough, it's stuck..."

Gu Cheng sighed helplessly and stopped the life infusion.

As the martial arts he practiced became more and more advanced, he now felt that relying on life alone was not a good choice.

This is similar to doing math problems. If you ask a primary school student to do the Olympiad questions, even if he is given ten years to take the exam, he still won't be able to do it.

In the final analysis, it still depends on factors other than time.

"By the way, didn't Venerable Lingque say before that if there is anything you don't know, you can go to Tang Lingyu for advice?"

Gu Cheng's eyes suddenly lit up.

Just as he stood up and prepared to look for the direct disciple of the garrison commander.

Dong Dong Dong——

Outside the gate of the courtyard, there was a rhythmic knock on the door.

Cao Jianxin was resting in the yard after practicing a set of swords.

Hearing someone knocking on the door, he opened it.

A tall, heroic female lieutenant with short hair was standing at the door, holding a wooden box in her hand.

"Are you... Lord Tang?"

Cao Jianxin looked at the appearance of the visitor and was surprised.

He had long heard of the name of this disciple of the garrison commander.

"Master Tang? Why are you here?"

"I came to see Gu Cheng..."

Tang Lingyu responded indifferently.

Then she looked up and saw Gu Cheng just walking out of the door, and her eyes suddenly lit up.

She hurriedly passed Cao Jianxin and walked towards the black-shirted young man.

"Chief Gu, I'm here to give you medicine."

Tang Lingyu's tone was slightly fearful, and she raised the wooden box in her hand to Gu Cheng and explained:

"This is the secret medicine left by my master, which has a miraculous effect on practicing Canglong Bailian.

Aunt Lingque said you should be able to use it, so she asked me to bring it all to you."

"Thank you! You came at the right time, and I just have some questions to ask you."

As he said that, Gu Cheng smiled and invited the short-haired woman into the house, and closed the door casually.

"..."

Looking at the closed door.

Cao Jianxin blinked his eyes, with a strange look on his face.

As far as he knew, this disciple of the garrison commander had always been arrogant and rude to the opposite sex.

Why was he so polite to Gu Cheng now, and even a little afraid of him?

It took him half a day to get a reward.

Could it be that his roommate had made some big news again?

-----------------

The biggest advantage of practicing martial arts is that you can continue to move forward along the path that your predecessors have taken, so you don't have to grope for it all over again.

Gu Cheng invited Tang Lingyu to sit down and brewed a pot of hot tea.

At the same time, he asked about the problems he had encountered when practicing krypton life before.

Tang Lingyu sat next to Gu Cheng, listened attentively, and felt a little happy.

Hehe~ Even though you were so powerful in the martial arts arena just now and Aunt Lingque was astonished by you, you still have to ask me when practicing "Blue Dragon Hundred Refining"?

But as Gu Cheng asked more and more questions, he didn't stop for an incense stick of time.

The expression of this short-haired beauty became more and more subtle.

"It has only been about an hour since Chief Gu obtained the secret book of the martial arts?

In such a short time, he has such a comprehensive understanding of "Blue Dragon Hundred Refining"? "

Tang Lingyu pursed her lips lightly, and sighed in her heart.

This Chief Gu's comprehension is really terrifying. No wonder he is valued by the Xu family and becomes the successor of the thunder method.

"That's about it..."

After Gu Cheng finished speaking, he quickly drank a sip of tea to moisten his throat, and his expression was a little embarrassed.

He had almost all questions when he was practicing just now, so he had to pick some of the most obscure and difficult places to ask.

Tang Lingyu is indeed worthy of the title of genius.

After just one listen, she memorized all of Gu Cheng's questions.

After she sorted them out in her mind, she pointed at the pages with her slender fingers and patiently explained them word by word.

Just look at the two of them sitting side by side, reading a book together.

It feels a bit like the school girl in the previous life explaining math problems to her poor classmate.

Gu Cheng sat next to this short-haired beauty, quietly listening to her explanation, but his brows were getting deeper and deeper.

Tang Lingyu may have tried her best to make the problem easy to understand, but it was still very difficult for a poor student.

It's like a pancake. Even if the female student chewed it up and spit it out to him, it would be nothing more than a piece of iron slag that is hard to swallow.

But anyway, the cost of understanding is still much simpler.

"I'll think about it again..."

When Tang Lingyu finished explaining, Gu Cheng nodded as if he understood, then slowly closed his eyes and continued to pour life into it.

Looking at the handsome young man who closed his eyes and thought.

Tang Lingyu sat quietly aside, not in a hurry at all.

She had personally experienced how obscure and difficult the second volume of "Blue Dragon Hundred Refining" was.

At the beginning, she was taught by her master, and it took her nearly a month to get started.

This Chief Gu has such a strong understanding, and he has a famous teacher to guide him.

I guess it won't take ten days for him to reach the threshold of this technique?
