By this time, the woman had stopped playing the piano and had turned to music theory.

Several children were listening carefully to the sermon and teaching of this female gentleman, and they were unaware of Li Xuan outside the window.

The woman who was lecturing paused, glanced up at the window, and quickly withdrew her gaze and continued to teach music theory.

Li Xuandu was about to turn around and leave, when he suddenly found that it was snowing.

The sky, which was originally quite clear, had become dark at some point, like a piece of white paper seeping some ink, showing a dull dark blue color, which made people's mood become gloomy.

Li Xuandu, who was originally planning to leave, suddenly heard the woman in the house speak: "Since it is snowing, it is better to wait for the snow to stop before leaving." ”

To Li Xuandu's surprise, the woman's appearance seemed to be ugly, but her voice was tactful and extremely disproportionate.

Li Xuan didn't refuse, but he didn't enter the piano house, and still stood under the porch outside the piano house.

The woman didn't insist on it, and continued to talk about music theory to the children.

Li Xuandu put his hands behind his back and closed his eyes. After a while, the sound of the piano sounded in the piano house, elegant and poignant, and it didn't take long to play, and suddenly the sound of the piano went up, louder and higher, and the sound was extremely sharp, which made people feel sad.

Suddenly, the sound of the piano suddenly raised a few tones, and with a "zheng" sound, it seemed that a string had been broken.

Li Xuandu opened his eyes and turned to look into the piano house.

The woman was looking at the guqin in front of her, and sure enough, a string was broken, she looked at the broken string in a daze, and sighed lightly: "Okay, let's stop today's class here." ”

The children in the piano house suddenly burst into cheers, said goodbye to Mr. and left the piano house with a smile, and did not forget to turn their heads to look at him when they passed by Li Xuandu.

Li Xuandu smiled in return.

After the children ran out, Li Xuandu turned around and walked into the piano house and asked, "The girl left me down, I don't know what to learn?"

The woman put the guqin in front of her aside, got up and bowed, and said, "This son doesn't seem to be an ordinary person. ”

Li Xuandu pretended to be surprised and said: "I'm not a son, I'm just an account room, I don't know what the girl means by this?"

The woman smiled and said indifferently: "Since the son doesn't want to tell the truth, then forget it." ”

Li Xuandu frowned slightly, only feeling that he didn't seem to be going out today, first the middle-aged scribe with a lame leg, and now this strange woman who is proficient in music and rhythm, all of them seem to be hidden, and they all seem to see his details, which makes him a little uncomfortable.

Seeing Li Xuandu's puzzled face, the woman hesitated slightly, and said in one sentence: "The son's sword qi is contained but not released, it is terrifying, how can he be a mere account man." ”

Li Xuandu was taken aback, and subconsciously looked inside his body.

At first glance, it seemed that there was no big problem, but under Li Xuandu's intention, he suddenly saw many clues, which really made Li Xuandu startled.

I don't know when, there seems to be a black mist entrenched in the sea of dantian qi in the body, and the thunder in the mist is faint and disappears in a flash.

As long as you set foot in the Qi Realm, you can open the Qi Sea Storage Machine in the Lower Dantian, and after entering the three realms of the hall, you can open up the Great Zhou Tian in the body, you don't have to deliberately run the Qi machine, the Qi in the Qi Sea in the body can circulate endlessly, if there is something unusual in the Qi Sea, there will be a sense of pain, so Li Xuandu will not deliberately look at the Qi Sea on weekdays. People in the world often say that the light is dark, and Li Xuandu is guilty of this problem.

Li Xuandu was dual-minded, while watching the six roads and listening to the eight directions, he continued to look inward at the dantian, as soon as his divine sense entered the dantian, in an instant, the sea of qi expanded rapidly like an ocean, until it was as big as the sea of heaven, but that little bit of divine consciousness was just the opposite, as the sea of qi became larger, it shrank sharply, turned into a point of needle, and in an instant, it disappeared into the ocean without a trace.

It was only at this time that Li Xuandu really saw the scene in the sea of qi clearly.

In the depths of his sea of qi, a black "giant tree" was rooted, like heaven and earth, with thunder flowing on it, and on the trunk of the "giant tree", there were many black mist like vines.

This "giant tree" is the "Anti-Heavenly Tribulation" sword qi that resides in the "human world", I don't know when it has taken root in his body, and it has grown to this point, and the black mist that is entangled in it is the sword intent of the "Taiyin Thirteen Swords". Originally, because Li Xuandu's cultivation of the "Taiyin Thirteen Swords" was still short, the sword intent of the "Taiyin Thirteen Swords" could not "live alone", but he didn't expect that because he repeatedly used the "human world", the "Anti-Heavenly Tribulation" had already taken root in his body, and at this time, the "Taiyin Thirteen Swords" depended on the "Anti-Heavenly Tribulation" to live.

The two were interdependent, so that Li Xuandu unintentionally, the sword qi turned and escaped, but he himself did not know it.

Li Xuandu withdrew his inner vision, and already understood why the middle-aged scribe with disabled legs stopped talking to him, and specifically mentioned the senior brother Situ Xuance, and the later Qing Luanwei also kept an eye on him, at that time he thought that the person was a little too sensitive and suspicious, but now it seems that it should be more like a great enemy.

This is like someone posted a note behind Li Xuandu, everyone can see it, but Li Xuandu himself can't see it, which gave rise to many incidents that shouldn't have happened.

Of course, there is also the woman in front of her, even if Li Xuan has a sword qi rotation and does not have enough realm cultivation, it will never be able to see it, since she can see through it, it means that this woman is not as simple as an ordinary violinist.

After thinking about this, Li Xuandu returned the salute to the woman, and said sincerely: "I didn't know that something went wrong in my practice, thank you girl for waking up, otherwise I don't know that it will cause trouble." ”

The woman shook her head and said, "Childe doesn't need to thank you, just now I thought that Childe was here to trouble me, so I made a temptation." ”

Li Xuandu smiled bitterly and was speechless.

The woman sat down next to the guqin again, replaced the broken strings, tuned the strings, and played again.

At first, the rhythm of the song was the same as that played by Fang Cai, but later it turned higher and higher, and this time the strings were not broken again, apparently because the mentality of the person playing it was more peaceful than just now, so the rhyme of the piano was in danger, and the weight was light, and it turned up effortlessly.

This song is sometimes impassioned, sometimes gentle and elegant, although Li Xuandu does not know the music theory, but he feels that the tune played by the girl in front of him is peaceful and neutral, which makes people listen to only the beauty of the piano sound, but there is no poignant and sad meaning just now.

After playing for a long time, the rhyme of the piano gradually slowed down, and it seemed that the sound of the piano could not help but go away dozens of zhang, and then to a hundred zhang away, and finally the subtlety could hardly be heard again.

When the sound of the piano seemed to stop, there were one or two extremely low and thin flute sounds from outside the sky.

After a while, the sound of the flute gradually sounded, just the opposite of the sound of the piano gradually moving away, the sound of the flute was getting closer and closer, first a hundred zhang away, and then dozens of zhang away.

The sound of the piano is high-pitched, the sound of the flute is low, and when it is extremely low, after a few circles, it is low again, and although it is extremely low and thin, each syllable is still clearly audible.

Gradually, there are occasional pearl jumps in the bass, and the complex sound gradually increases. First like a group of flowers competing for beauty, flowers are clustered, and then like spring flowers falling, but hearing the sound of rain Xiao Xiao, a desolate and solemn image, drizzle, if there is nothing, finally all silent.
