Then Chu Yun destroyed dozens of books. Among these destroyed books, he also found that some of them had the words "Li Xiao Li's Flying Knife" written on the covers.

This made Chu Yun very excited, at least it was very likely that there was a secret to Xiao Li flying knife here.

Half a cup of tea passed, and a thrill suddenly flashed in Chu Yun's heart, because he saw the cover of a secret book with Xiao Li flying knife suddenly written on it, and there was no sign of being destroyed after taking it out.

"System prompt: I detected that the host has "Little Li Flying Knife·Peerless Martial Arts", do you learn it?"

"study!"

What can I hesitate about this? Is there any peerless martial arts that I don’t learn before me?

But in the next second, Chu Yun was in a tragedy.

"Improving Xiao Li's flying sword martial arts to the initial level, consuming 10 million skill experience points, is it upgraded?"

"upgrade!"

"System prompt: Introductory conditions for "Xiao Li Flying Knife·Perfect Sword Technique": Understanding reaches 8 points or above: to satisfy; one superior hidden weapon technique reaches the pinnacle of the state of creation: satisfied; one superior sword technique reaches the pinnacle of the state of creation: not satisfied. Learning failed."

"Damn..." Chu Yun felt that this was the most afflicting thing in his life, and he even failed to upgrade his martial arts.

This happened when I got the Blue Sea Tide Song last time, but at that time I didn’t even learn the basic music, so I naturally failed to practice. But now my basic sword technique has reached the level of returning to nature, and I even practiced an advanced sword technique, "Earth Evil Sword Technique", but I couldn’t even get started with Xiao Li’s flying sword.

After reading the system prompt, Chu Yun couldn't help but feel deeply moved. The learning conditions of Li Xiao Li Flying Dagger are too high, right? He actually needs two excellent martial arts to reach the pinnacle. If he is an ordinary genius with a qualification once in a thousand years, it is estimated that it will take twenty or thirty years to practice Xiao Li Flying Dagger.

It is not difficult to practice one of the best sword techniques to the pinnacle of the world. The difficulty is that Chu Yun has not learned the best sword techniques now.

Whether it was the inheritance hall of Qingcheng Sect before or the Sutra Library of Emei Sect, I learned a lot of advanced sword techniques, but I didn’t find any excellent sword techniques.

After all, neither of these two sects learn to learn swords.

"Forget it, I'm not in a hurry to upgrade Xiao Li Feidao. Anyway, I've learned it now, and there will always be a chance to improve in the future." Chu Yun murmured, and then continued to search for books on the bookshelf.

An unexpected surprise, I actually got a boxing technique, and it was a masterpiece.

This is probably the secret book that the owner here got. Put it here to count. Anyway, he has never heard of any successor of Xiao Li Feidao who has learned boxing.

"System prompt: I detected that the host has "Secret-free Sword Technique·Excellent Sword Technique", do you learn it?"

"study!"

"Hahaha..." Chu Yun couldn't help laughing excitedly. It was like someone was sending a pillow to sleep. He was just thinking about where to get a good knife skills in the future, so he came to his door.

However, Chu Yun thought again and thought that this should be the case. Since the owner of this place left behind the secrets of Xiao Li flying sword here and knew the learning conditions of Xiao Li flying sword, he would naturally leave corresponding secrets here.

In this way, there should be another book on hidden weapons and martial arts?

This is an unexpected surprise. Although Chu Yun has many martial arts in his personal attribute panel now, they are basically made from sects in Qingcheng or Emei. Many of these martial arts cannot be used in public, let alone as sect martial arts in Xuanyue Villa.

Sure enough, just as the books on the bookshelf were about to be picked up, Chu Yun finally saw a secret book as he wished.

"System prompt: I detected that the host has "Ice Soul-Saving Needle·Superbing Hidden Weapon", is it learned?"

"study!"

It was also the first time Chu Yun heard about the name of the Ice Soul-Death Needle. It can be seen that this is also a martial art that has been lost to the world for hundreds of years. It is just a superior martial art, so the name has not been passed down.

Chu Yun filtered the practice method of the Ice Soul-Slaying Needle in his mind, and was immediately surprised. Could this be the legendary life and death talisman?

If you want to talk about the difference here, it is probably that the life and death talisman belongs to the special martial arts of control, and it is not considered a hidden weapon technique. The Ice Soul-Slaying Needle is a hidden weapon technique that directly kills people's lives.

The advantage of the Ice Soul-Deathing Needle is that you don’t need to prepare any hidden weapons. To practice the Ice Soul-Deathing Needle, you need to practice Yin and Cold internal strength, and then use the internal strength to condense the Ice Soul-Deathing Needle and directly attack the human body with the ice needle.

After the ice needle enters the body, the cold air instantly explodes in the target body, directly freezing the person, which is extremely powerful.

The power of this hidden weapon is not only related to the person using his hidden weapon cultivation, but also to the internal power level he has cultivated.

Take Chu Yun for example. The Nine Yin Scriptures he practiced are a stunning skill, and he has already practiced to the realm of synthesis. The power of this Ice Soul-Snatching Needle in Chu Yun's hands is definitely no worse than that of the top hidden weapon techniques.

Chu Yun was naturally very satisfied with this. His current situation in Xuanyue Villa already had the Xuan Bing Art. Coupled with the Xuan Bing Finger and this Ice Soul-Slaying Needle, it can basically form a martial arts system. At the same time, these three martial arts can be considered Chu Yun’s own, and he can be promoted on a large scale.

In addition, the Nine Yin True Sutra can also be regarded as the unique skills of Xuanyue Villa, but the Nine Yin True Sutra is too famous in the world. If you do not have a certain strength, making this martial art public will definitely attract the covetousness of most people in the world, and you will definitely be in trouble at that time.

Chu Yun guessed that there should be even lower-level secrets on this bookshelves, but they have been ruined because of their age.

Next, Chu Yun walked to the wooden stand piled with porcelain bottles, boxes and other miscellaneous items. He actually did not expect much of this place. No matter it is precious medicinal materials or elixirs, there are few that can be kept for six or seven hundred years.

Sure enough, Chu Yun opened the porcelain bottles, jade bottles, and boxes one by one, and the things inside were either shriveled or rotted and disappeared.

The remaining six large boxes were very real. Two of them contained golden gold, two of them contained jewelry and jade, and the remaining one contained some ore.

Chu Yun found that the quality of these ores was actually very high, and they could basically be used to create medium-grade treasure soldiers.

The weapons contained in the last box, OK! They are all hidden weapons, flying knife hidden weapons.

However, the box was not full, and there were only thirty little Li flying knives that were as thin as cicada wings. There was also a belt made of Tianshan ice silk. The thirty little Li flying knives were all inserted on the belt. If you didn't look carefully, you would only think that the handles of the knife were decorative objects.

Although the yellow and white thing is dazzling, Chu Yun feels that the most precious of these boxes is this belt and the thirty Li flying knives.

This should be a complete set of Xiao Li's flying knives. As for the flying knives I found in the tomb of Tianmu Mountain before, they should be some scattered objects.

Chu Yun directly replaced the belt with the brocade belt on his waist, which was very suitable.

Chu Yun was not ready to take away the remaining things here. In fact, it was not easy for him to take them away even if he wanted to. These things were too heavy, so Chu Yun could not hire an escort agency to escort these things. Then I guess the daylily would be cold when I returned to Xuanyue Villa.

Chu Yun opened his attribute panel and was quite excited. There were already two peerless martial arts on it, one of the Nine Yin True Sutras Volume 1, which is the internal power of the Nine Yin True Sutras, and one of the Little Li Flying Knife.

These two martial arts are both super unique skills that are well-known in the martial arts world.

"Learn this Xiao Li flying knife first." Chu Yun murmured, then checked the remaining experience value in his account.

Skill experience: 120 million points; experience: 780,000.

Chu Yun did not look at the fractions. Based on his current situation, these fractions had no meaning to him.

Chu Yun thought about it in his mind that his swordsmanship, Tiancheng secret martial arts, had been upgraded to 31%. After all, he had high understanding and had very obvious advantages in this regard. With his remaining experience value at present, it was enough to increase the secret martial arts to 90%. As for higher, it was not something Chu Yun could do.

However, with this 90% understanding, it will be much easier for Chu Yun to upgrade the traceless sword technique.

In the end, Chu Yun spent less than three million points of experience to upgrade the traceless sword technique to the pinnacle level. Chu Yun did not intend to upgrade this martial arts to a higher level for the time being. Although the advanced martial arts realm has reached the level of returning to nature, he can immediately comprehend the secret martial arts, but who made Chu Yun not have enough experience now? Even if he comprehend the secret martial arts, it is not very meaningful. Instead of doing so, it is better to improve the Xiao Li flying sword realm.

"Improving Xiao Li's flying sword martial arts to the initial level, consuming 6.12 million skill experience points. Will I upgrade?"

"upgrade!"

Huh? After choosing to upgrade, Chu Yun realized that the experience required to upgrade Xiao Li Feidao this time was much less than before.

Could it be that improving the understanding of swordsmanship in Tiancheng will also increase the understanding of Xiao Li’s flying sword?

Chu Yun recalled the system prompt just now that there are three conditions for upgrading the Li Xiao Li flying knife, one is understanding, and the remaining two are sword technique and hidden weapons. In other words, this Li Xiao Li flying knife is a martial art between knife technique and hidden weapons.

This is definitely a good thing for Chu Yun, because it indicates that whether it is the sword technique or the hidden weapon, it can add to the cultivation of Xiao Li's flying sword.

According to Chu Yun’s previous life, the experience value required to get started with a unique skill is about 50 million to 100 million, and the experience value required for each upgrade is doubled, or even more than doubled. It is conceivable how difficult it is to cultivate a unique skill to the top.

As Chu Yun introduced Xiao Li's flying sword, he also gained a deeper understanding of this martial art.

According to conventional sayings, any martial arts has six realms from the beginning to the return to the essence. Xiao Li Feidao also has six realms, but on this basis, it has another way of dividing it.

Hand knife, heart knife, mind knife.
