The collection of books borrowed from Tianshulou must be returned at the end of each month.

Today happened to be the last day of the end of the month, and after Ye Xuan sent Guo Zitian away, he took the borrowed formation book to the Tianshu Building.

The reason why I borrowed the collection of formation books was because the knowledge of formations recorded in the "Book of Heavenly Formations" was too profound.

"The Book of Heavenly Formations" is not an introductory formation book, and the formations recorded in it are both mysterious and profound, and it is difficult for people who have not learned the knowledge of formations to understand.

Ye Xuan was not in a hurry to learn the Heavenly Book of Formations, but he also needed to slowly get in touch with some formation knowledge.

Regardless of whether you specialize in formations in the future or not, it is always beneficial to know some knowledge of formations.

Tianshulou is located on the main peak of the Heavenly Sword, and it is a seven-storey, imposing building.

Tianshulou is very quiet, because there are no martial arts secrets in Tianshulou.

Since few people came to Tianshulou, the sect did not send disciples to manage Tianshulou, but no disciples came to clean it once in seven days.

There is usually only one old man in charge of guarding Tianshulou.

The old man has white hair, but there are no wrinkles on his face, so it is difficult to judge his age.

The appearance of the crane hair and childish face shows that the old man's cultivation is definitely not low, and he should be an elder, but he doesn't know which generation.

Ye Xuan entered the Tianshu Building, saw the old man, and greeted politely: "Old man." ”

"Call me old man?" the old man frowned.

Ye Xuan saw that he was angry, so he explained: "The disciple doesn't know your identity, so he doesn't dare to call him indiscriminately, if he calls the wrong generation, it will be bad." Therefore, it should be appropriate to call Mr. Lao. ”

The old man nodded and said, "This explanation is okay, what are you doing in Tianshulou?"

"Oh, the book will be returned at the end of the month. Ye Xuan said and took out the book in his arms and put it on the table.

There was also a "Sword Qi True Solution" under the formation book, so I brought it out together.

The old man of Tianshu saw the "True Solution of Sword Qi" in Ye Xuan's hand, and said casually: "Young man, if you are strong, you should practice the sword technique well, practice sword qi and learn formations, be careful and not refined. ”

Ye Xuan was stunned for a moment, and said in his heart that his divine thoughts were formless and substantial, how could this old man see that his divine thoughts were strong?

Is there an old guy in every library building?

Ye Xuan grinned and asked, "Old gentleman can see the strength of my divine thoughts?"

"This is not difficult, when you cultivate to a higher level, you will naturally understand. I see that your divine mind is stronger than ordinary people, so I advise you to practice the sword technique well, and don't be too ambitious. The old man said.

"If I can practice the sword technique, I would be willing to practice it, but the sect won't practice it. Ye Xuan replied.

The old man frowned and said, "Although the second sword trick requires a lot of contribution points, as long as you have the strength of the first sword trick, it is not difficult to earn contribution points to exchange for the second level. ”

Ye Xuan smiled faintly and said, "The problem is, if I want to continue cultivating the Imperial Sword Technique, what I need is not the second level, but the third level. ”

The old man's expression was stunned for a moment, and he twisted his eyebrows and said, "Young man, don't fool me, otherwise be careful that I will clean you up." ”

"Naturally, I don't dare. ”

The old man groaned for a while, stretched out his hand and pointed to a flying sword enshrined on the table in the corner, and said, "Hey, I don't believe it, the sword is there, let me see your sword trick, if you lie, you will be unlucky." ”

Ye Xuan smiled calmly, raised his hand and made a move, and shouted softly: "The sword is coming!"

Boom!

The flying sword immediately came out of its sheath and flew into Ye Xuan's hand.

Seeing this, the old man's eyes suddenly lit up, and he said with a smile: "Interesting, how many years have you not met the little guy who has practiced the second sword technique?"

"Is the old gentleman planning to teach me the sword technique?" Ye Xuan joked.

The old man immediately shook his head: "That can't be taught, what you practice is 'sword return', mine is 'sword does not return', you can't mislead people's children." ”

"The sword doesn't return?" Ye Xuan asked puzzled.

"It's none of your business. However, I can remind you that if you have cultivated the sword technique, you can indeed continue to cultivate sword qi, because the two are originally one. It's just that there are thousands of mediocre talents in the world, and there is no way to have both, so the Heavenly Sword Sect separates the sword technique from the sword qi. The old man said.

"The Imperial Sword Technique and the Sword Qi are originally one?" Ye Xuan heard this for the first time.

"That's right, this is a long time ago, and few people have known about it since the Imperial Sword Pavilion was separated from the kendo academy. I see that your kid has a good talent, since he has practiced the second sword technique, then try to cultivate sword qi. Even if you can't comprehend the subtleties between the two, cultivating sword qi can increase the power of the sword technique. The old man continued.

"Okay, thank you, old man, for your advice. Ye Xuan thanked.

"Alright, you can go back. The old man waved his hand impatiently to drive people away.

Ye Xuan thought for a moment and asked, "Is there a collection of books in the Heavenly Book Building, or about the 'Confession Array'?"

"Tell you about the formation, why don't you go back to cultivate the sword qi honestly, and find the formation book?" the old man said with some anger.

"I'm just interested in the people who are in the 'array' and want to know about it. Ye Xuan replied.

"There are no books related to the Confession in the Heavenly Book Building. Speaking of this formation supreme, it is a very legendary existence. Although he has never been a god emperor in his life, he also shines in an era. The Heavenly Sword Sect's Mountain Protection Array is arranged according to the half-page fragment of the Array Array, but I can't show it to you. Let's go back and practice hard. The old man said.

......

After Ye Xuan came back from the Heavenly Book Tower, he began to comprehend the connection between the Imperial Sword Technique and the Sword Qi.

However, before cultivating the sword qi, it was difficult to comprehend the subtleties.

So, Ye Xuan immediately decided to cultivate his sword qi.

Ye Xuan's comprehension in the way of the sword was already very high, and if he cultivated normally, he would definitely be able to practice sword qi in less than three years.

For the disciples of the Kendo Academy, three years of practicing sword qi was already a very terrifying speed.

But for Ye Xuan, cultivating martial arts has always been calculated by days.

Directly enter the timeless void, cultivate the Nine Swords of Wind and Thunder in the realm of selflessness, and comprehend the sword qi.

In just three days, the swordsmanship took the most critical step, and in a wind and thunder sword light that illuminated the sky, the swordsmanship officially stepped into the realm of transcendence.

At that moment, the sword and the palm seemed to be fused into one, and the fingers could feel every tremor of the sword, as if it was connected by blood.

Not only that, but when the sword technique broke through, he also cultivated the sword qi at the same time.

Originally, if you want to comprehend the sword qi, you need to at least reach the peak of the sword art realm.

And the sword technique that is out of the realm of divine transformation makes it easier to comprehend the sword qi.

Therefore, the moment Ye Xuan reached the realm of swordsmanship, the sword qi surged out, converging into a snow-bright sword qi, illuminating the sky.

It took three days to practice the sword technique to the point of perfection, and to cultivate the sword qi.

This terrifying speed has gone against the sky to the point of being terrifying.
