Where Lin Fei's gaze fell were rows of bookshelves. Saber techniques, sword techniques, fist techniques, etc. Body refining level, acquired level, and innate level were all included. As for the quantity, it's at least ten times more than the Nine Profound Sect. This is the foundation of the Great Chang royal family.

After establishing the Great Chang dynasty, the founder of the Great Chang began to collect martial arts techniques from all over the world. Many martial arts were collected by the founder of the Great Chang. They were put into the secret collection of royal martial arts. Therefore, there were so many saber techniques here.

Lin Fei didn't intend to examine the secret books one by one. He took a deep breath. Then, he released all his saber intent.

"Boom."

Lin Fei's saber intent enveloped the entire secret martial arts collection.

Now Lin Fei's saber intent was not just perfection anymore but it had surpassed perfection. The cultivation progress had reached 55%. That is to say, Lin Fei's saber intent only needed to increase the cultivation progress by another 45%, then he could evolve the saber momentum. Like the innate level saber techniques such as the Three Abyssal Sabers, and Twenty-Three Sabers, only ten were needed!

"I wish to evolve the saber momentum. If you want to exist forever, then voluntarily integrate into my saber intent at the perfection level, and help me evolve the saber momentum. By then, you will all become the cornerstone of my Saber Dao. In the future, if my saber path transcends, you can also exist forever!"

Lin Fei said calmly. He was doing the same as he did in the Nine Profound Sect Martial Arts Pavilion. Using the method of "drawing a big pie", he "bamboozled" these saber techniques. Of course, it's not entirely a bamboozle. These saber techniques, once integrated into Lin Fei's saber intent then evolved the saber momentum. These saber techniques could indeed exist forever.

However, it was very difficult.

Now, Lin Fei had only comprehended the saber intent. He hadn't even evolved the saber momentum yet. What if he got killed halfway through? Then the so-called Saber Dao will naturally become empty talk.

However, for these saber techniques, whether they were willing or not, it was all voluntary. Some saber techniques were willing to gather dust on the bookshelves, unknown for a lifetime. But some saber techniques were willing to make a big splash, to stand out.

Therefore, Lin Fei's words were voluntary on both sides, not forced. If there were those who were willing to integrate into his saber intent and become the cornerstone of his Saber Dao, he would naturally be happy.

Lin Fei showed a pure saber essence, emitting a terrifyingly sharp edge. If Lin Fei wanted these saber techniques to voluntarily integrate into his saber intent at the perfection state, he naturally needed to demonstrate some characteristics worth following for these saber techniques.

For instance, his saber essence, which was like a real treasured saber, was invincible. Moreover, his saber intent integrated the saber intent of pulling the saber and the heavenly saber, which was very special.

Martial artists choose martial arts. But why wouldn't martial arts have a choice to choose martial artists? Now, it's time for these saber techniques to choose Lin Fei.

"The Ripple Saber Technique at the perfection stage is willing to integrate into your saber intent to increase the foundation of saber intent."

"The Shadow Saber Technique at the perfection stage is willing to integrate into your saber intent to increase the foundation of saber intent."

"The Swallow Saber Technique at the perfection stage is willing to integrate into your saber intent to increase the foundation of saber intent."

In Lin Fei's mind, the system's voices sounded one after another. These were all saber techniques that voluntarily integrated into his saber intent.

However, these saber techniques were all acquired-level. So far, at least, none of the innate-level saber techniques were willing to integrate into Lin Fei's saber intent.

These acquired saber techniques might be numerous. However, without the integration of innate saber techniques, it was too difficult for Lin Fei to evolve the saber momentum.

Even though the royal family had a deep foundation and many acquired saber techniques, most acquired saber techniques were similar to the Nine Profound Sect's acquired saber techniques. They couldn't increase the cultivation progress of saber intent by much.

Lin Fei's saber intent cultivation progress was slowly improving.

56%, 57%, 58%, 59%, 60%......

Indeed, it was very slow.

Gradually, Lin Fei didn't even know how many acquired saber techniques he had integrated. Finally, the cultivation progress of his saber intent also stopped. It finally froze at the number 78%. Compared to the previous 55%, it had only increased by 23%. However, there was still a gap from 78% to 100%.

"Not a single innate saber technique is willing to integrate into my saber intent?"

Lin Fei frowned. Back at the Nine Profound Sect, even saber techniques like the Three Abyssal Sabers, Twenty-Three Sabers, and so on, all voluntarily integrated into his saber intent. But in the secret martial arts collection of the royal family, it seemed that these innate-level saber techniques were all very aloof. They were unwilling to integrate into Lin Fei's saber intent.

"If I evolve the saber momentum. All innate-level saber techniques will be independently presented in my saber momentum. You will no longer be ordinary. You will all become unique saber techniques!"

Lin Fei spoke again. The next moment, Lin Fei clearly felt it. It was as if a surge of extremely sharp breaths suddenly awakened.

The so-called saber momentum, in fact, was the martial artist who integrated all the saber techniques learned into a powerful suppressing force.

In the saber momentum, there could be individual saber techniques present. Even some saber techniques carry unique saber intents, all could be presented in the saber momentum.

That is to say, once covered by the saber momentum, the enemy might face attacks from countless kinds of saber techniques and saber intents. This was the terrifying aspect of saber momentum!

Of course, many martial artists integrated saber intent and saber techniques completely. But Lin Fei made a promise he would retain these saber techniques in the saber momentum. He did not believe those innate-level saber techniques would remain indifferent to his words.

The next moment, in Lin Fei's mind, the system's voice indeed sounded.

"The Perfection Stage Eternal Night Saber Technique is willing to integrate into your saber intent, increasing the foundation of saber intent."

"Your saber intent cultivation progress increased by 5%."

"The Perfection Stage Samsara Saber Technique is willing to integrate into your saber intent, increasing the foundation of saber intent."

"Your saber intent cultivation progress increased by 5%."

"The Perfection Stage God Slaying Saber Technique is willing to integrate into your saber intent, increasing the foundation of saber intent."

"Your saber intent cultivation progress increased by 5%."

With the fall of Lin Fei's words, one after another saber techniques were willing to integrate into Lin Fei's saber intent actively. Moreover, they all could improve the cultivation progress of saber intent by 5% in one go. This indicated that these saber techniques were all innate-level saber techniques.

Moreover, they were almost comparable to the Three Abyssal Sabers, Twenty-Three Sabers among the innate-level ones. They could be considered top-notch saber techniques!

Lin Fei's saber intent was making rapid progress all the way.

83%, 88%, 93%, 98%......

"Boom."

Lin Fei's mind was booming. Finally, when Lin Fei's saber intent cultivation progress reached 100%, his saber intent began its metamorphosis!
