Library area is not small, two people look for a circle, just in the corner of a small open space to find Han Yangshu.

At this time, Han Yangshu held a long sword, bent his knees and sank his waist, and gazed at the bookshelf in front for a long time. An open ancient book was placed on the bookshelf. It was obvious that he was fully aware of the sword skill, and even Gu Fenghua and Luo en were not aware of it.

"Jianling, jiuxiao!" Han Yangshu suddenly a light drink, long sword stab out.

It turned out that he was understanding the sword. This is the most powerful unique skill of Nanli sect. There are nine levels in all. However, the outer disciples can only learn the first three levels, and the latter can only be found in the library.

Gu Fenghua felt that the sword's style and meaning were far more than Han Yangshu's sword lingjiuxiao, which was used in the two doctrines. However, it was obvious that he had not yet realized the essence of the sword. Not only did he not reach the realm of the unity of Swordsman and man, but also there was no shadow of separation. The power of the sword was not up to his previous level.

"Oh, it's too hard. I failed again." Han Yangshu's heart and mind are all concentrated in this sword, but he still doesn't find Gu Fenghua's arrival. He sighs, closes his eyes again, and is ready to continue to try.

Seeing that he was fully understanding the sword skill, Gu Fenghua and Gu Fenghua stood aside to observe it.

This time, Han Yangshu took a longer time to prepare. After more than half an hour, he opened his eyes again and stabbed.

When the sword broke through the air, there was a gentle buzzing sound, and his eyes were shining. It was obvious that he injected all the energy, even the power of life into the sword.

Unfortunately, when the sword was only half delivered, he was shocked all over, puffed out a mouthful of blood, and then fell straight to the ground.

"Yang Shu!" Gu Fenghua quickly stepped forward to hold Han Yangshu, and his fingers quickly sealed his blood.

"When... Did you come?" Han Yangshu noticed that Gu Fenghua and Gu Fenghua had already arrived at his side, but he didn't realize it. He wiped the blood stains on the corner of his mouth and said apologetically.

"Don't talk yet." Gu Fenghua took out a Taihe xuanhuandan and took it for him.

The curative effect of Tianjie Shengdan is needless to say. Han Yangshu just realized that his sword skill failed and suffered a backfire. His injury was not serious. He took the Shengdan and soon recovered.

"I made you laugh. I didn't expect that it was so difficult to comprehend the fourth realm of sword lingjiuxiao." Han Yangshu stood up, embarrassed to say.

He thought that he had reached the third level of Jianling jiuxiao cultivation, and it should not be difficult for him to understand the fourth level. But as soon as he started, he realized that he was completely wrong. The fourth level and the third level of Jianling jiuxiao cultivation are two different things. With his current strength, he can't understand it at all.

"Is this the fourth method of Jianling jiuxiao's cultivation?" Gu Fenghua curiously picked up the ancient book sword manual.

The sword skills in the sword score are well illustrated, as well as the experience of the past generations. Of course, not everyone dares to scribble on it. Only those who are recognized as a strong generation have the qualification and courage. With the sword skills on the page, Gu Fenghua can even feel the sword ideas coming into his mind.

This is also the treasure of the original sword manual. All the sword skills or holy methods like Jianling jiuxiao came from the top strong men at that time. When they painstakingly wrote down the sword manual, they naturally left their own understanding of the meaning of the sword. It's easier for later generations to understand the essence of the sword. However, after they extract it, they have no such effect.
