In the inner hall of Yuheng in Chenji Palace, a unicorn flower pigeon glides down above the courtyard, and then lands on Ouyang Hongye's raised hand. He stroked the pigeon twice with his free hand and threw it into the air.

The dove fell to the ground, cooed twice, and transformed into a little old man in a black and gray feather coat. Don't look at him as an old man, he is the sixth in the intelligence seven, his wrinkled skin and sagging eye bags are natural, and his age is actually only two hundred years old.

He respectfully saluted Ouyang Hongye, and then said, "Lord Hongye! According to our tracking in the past few days, the red-eared demon spirit really met with the desolate scorpion again, and Qingyun gave him an order. ”

"What's that?" Ouyang Hongye interrupted him anxiously as soon as he heard Qingyun's name.

The flower pigeon hurriedly responded: "He ordered the red-eared demon spirit to start moving, and asked him to close the seven-tone gate!" ”

"Well done! I'm going to send someone to investigate the matter of the Seven Tone Gates right away, is there anything else to report? Ouyang Hongye thought for a moment and asked.

"Not yet!"

After saying that, the flower pigeon changed back into the form of a pigeon, and flapped its wings a few times and flew into the air.

Ouyang Hongye had never heard anyone mention the existence of a seven-tone gate in Tucheng Qingyang, and he didn't know what this seven-tone gate was used for. After confirming the close connection between the Red Ear Demon Spirit and Qingyun's group again, he felt that he was the traitor in the royal city who secretly let go of Yaksha, and he couldn't help but feel a wave of anger rushing into his heart.

But now was not the time to be immersed in anger, he had to immediately set off and return to the Ouyang Ancient Mansion in the human world to see if Dong Muya and her hacker friend could find out the information about the Seven Sound Gate.

Recently, Dong Muya has fallen into a bottleneck in the study of the Qilie Array, and she has lost her sense of direction for a while. Compared with the Golden City and the Water City, the records of the remaining three castles are scarce, because these three castles have been relatively closed in the past, and they were managed independently by the lord of the castle.

Investigations need clues, and clues are often hidden in keywords or key information, even a little bit can make a big difference, and now these are what she and Min Entong are missing.

To this day, she admires this genius child so much, she once thought that her memory and ability to analyze things are outstanding, but Min Entong is far superior to her.

In the underground database of Ouyang Ancient Mansion, although all the materials on the bookshelf were sorted out by her, for those that were not commonly used, she sometimes had to rely on the records in the computer to find them, but this eight-year-old child had memorized the use of the database and the order of the materials in a short period of time.

For the same keyword, they went separately to investigate, Min Entong was always faster than her, and the answers he found were higher than his own in terms of number and efficiency. I have to admit that this child who was born from the Strange Array did inherit all the excellent genes of his parents.

On the surface, Min Euntong is not interested in anything other than his super terminal MM, but he also has his own ghost ideas in his little head.

Recently, he is planning how to let his uncle and Dong Muya meet, compared to the flowers and butterflies flying around his uncle, Dong Muya is the best candidate for his aunt in any way.

Ouyang Hongye returned to Ouyang's ancient mansion through the corridor and the maze path, and as soon as he pushed the door in, he saw a little boy standing by the courtyard pond enjoying the fish. Although I had heard Dong Muya mention this genius child for a long time, it was the first time for the two to meet. In fact, it was because Min Entong had been in front of the computer screen for too long that Dong Muya forced him to come out and relax his eyes.

Min Entong was taken aback by the strangely dressed Shu Huang who suddenly appeared in front of him, although he knew the things of the demon world thoroughly, but he had never seen a real guy. This Shu Huang looks much more handsome than his own uncle, he seems to have stepped off the cover of ancient romance novels drawn by famous illustrators, especially the two silver threads on both sides of his sideburns, which reminded Min Entong of Jin Yong's Condor Hero Yang Guo.

He thought to himself that this time was terrible, the demon world was really full of beautiful men like demons, and his own uncle was no play. But after thinking about it again, a smart woman like Dong Muya shouldn't judge people by their appearance, so she should give this strange Shu Huang a dismount first.

"Shu Xiao, who are you?" Min Entong deliberately pretended to be the innocence of children of the same age, and asked ignorantly.

"My name is Ouyang Hongye. You're Min Eun-tong, right? I heard Muya mention you! Ouyang Hongye wanted to reach out and touch Min Entong's head as he spoke, but he didn't expect him to dodge like a cat.

As soon as he heard that this strange Shu Huang called Dong Muya Muya, he was a little angry. Then the child's arrogant side was revealed, and he puffed out his mouth and said, "Well, the red leaves are so kind to my future aunt!" ”

Ouyang Hongye didn't know what kind of medicine was sold in this little gourd in front of him, but he was curious about how Dong Muya had become his future aunt after not returning to Ouyang Ancient Mansion for a few days, but he didn't expect that he would feel a little uncomfortable in his heart when he heard such words.

He pretended to be calm and smiled at Min Euntong, then entered the house and walked down the stairs to the door of the database, where the smell of smoke and coffee wafted from the half-hidden door as usual. He walked straight to the innermost big table, only to find that Dong Muya had fallen asleep on the table rarely.

Piled in front of her was a thick pile of student submissions, a pile of miscellaneous materials and notes, and an array of strange arrays. She was so tired, but at the same time she felt anxious and anxious that the search was making no progress and clueless, and she was in a hurry, and she kept having a low-grade fever, but she didn't know it.

Looking at her like this, how could Ouyang Hongye not feel distressed? Just wanted to call her up and go upstairs to sleep, but she suddenly woke up, raised her head from the table and stared at him for a long time, then rubbed her misty eyes and looked again, to make sure that she was not dreaming, she laughed and asked him, "Why are you here?" ”

"Don't worry about it so much, don't you know you're sick? Let's go upstairs and rest! Ouyang Hongye said in a commanding tone.

Dong Muya touched her face, it was indeed a little hot, but in her opinion, it was not to the point where she needed to rest, and Ouyang Hongye must have something important to go back to Ouyang Ancient Mansion to find her at this time, she asked very seriously: "What's wrong?" Tell me quickly, anyway, if you don't say that I always worry about it, I can't rest well! ”

Ouyang Hongye was helpless, so she had to tell her about the Seven Tone Gate, and when she heard the Seven Tone Gate, she paused for a few seconds, and then suddenly asked him: "Do you know what the Seven Tone is?" ”

"Isn't it the doremifasollatido invented by Westerners?" Ouyang Hongye answered her tentatively.

But seeing Dong Muya shook her head, she had the impression that the knowledge of Qiyin was much greater than that of a simple doremi, as if there was a volume called "Qiyin Luo" in "Tongzhi" that was dedicated to Qiyin. As soon as she thought that she and Min Entong had something to do again, she became more and more reluctant to rest.

Ouyang Hongye had no choice but to go upstairs to change her clothes so that she could go out to buy medicine for her, because demons don't have headaches and brain fever, so such medicine can't be found in Ouyang Ancient Mansion.

Dong Muya buried herself in the information again and began to search for records about the seven tones. Min Entong, on the other hand, focused on finding out if there was anything related to the Seven Sound Gate in the information of the demon world, and two people, one large and one small, were busy in front of a computer screen in the underground database.

Before meeting Dong Muya, Min Entong had thought about associating the notebook with the super terminal MM, but it has not been realized. Recently, because he has to go back and forth to Ouyang Guzhai to work with her, he has put his long-standing ideas into practice in one go, and now his notebook has become a Mini version of MM, although the memory and computing speed are not as good as the genuine brand, but it is much more convenient.

In the past, in the old house where his parents were killed, working alone would make him a little scary, but now with Dong Muya, everything has become much easier and happier. He has always decided everything with his own will and solved problems by his own thinking, but recently he has been subtly changing, he has become very obedient to Dong Muya's words, and even depends on her to the extent that he will immediately do whatever she asks him to do.

Dong Muya began to search for "Tongzhi", and sure enough, the thirty-sixth volume was called "Seven Syllables". Among them, the seven tones are described as mysterious and mysterious. The book records that the rhyme of the seven tones flowed from the Western Regions into Zhuxia, which was the general name for the area west of Yumen Pass and Yangguan in ancient times, and Zhuxia generally referred to the Central Plains of the Zhou Dynasty.

One of the passages says that foreign monks want to preach to the world in seven tones, because all the sounds in heaven and earth, whether it is the sound of cranes chirping or the sound of chickens and dogs, thunder and thunder, and gnats and flies, can be translated in seven tones, so human language is even more so. In this way, even if the language is not spoken, all people in the world can rely on the seven tones to understand the teachings.

As soon as she saw this, she was about to read down, but Min Entong suddenly said: "I can't search for these three words, but I don't know if it's useful to find something else." Legend has it that the Demon Spirit Clan will use a musical instrument to pass the boring time in growing herbs, and it can also relieve fatigue, and this instrument is very similar to the human lute. ”

"Pipa?!" Dong Muya sighed and began to read to herself, "The pipa is more established in seven evens, synthesized into twelve, should be twelve rhythms, the rhythm has seven tones, and the sound is in one tone, so it becomes seven tones, twelve rhythms and eighty-four tones, rotation and intersection, all are harmonious." ”

"Rotation intersects, everything is in harmony?" Min Euntong's attention was focused on the last sentence.

"You care about that too? First of all, I can be sure that this seven-tone gate should be composed of seven parts, representing Gong, Shang, Jiao, Zheng, Yu, Changgong, and Zheng. Then I guess that closing them off is what we call the interlude here, and then the harmony is meant to be the harmony of the rhythms, but here it is to make something tightly together. Dong Muya said confidently with his intuition.

"Tucheng Qingyang is exactly divided into seven layers, will the seven-tone gates be distributed in each layer?" Min Entong agreed with Dong Muya's analysis.

Dong Muya happily stretched out her hand and slapped Min Entong's little face twice, squeezed her eyes at him and said, "Sure enough, with a clue, it's different!" It always feels like we're very close to the answer! ”

Min Entong's face turned red after being slapped by her, and he lowered his head embarrassedly, but the corners of his mouth couldn't hide a smug smile.
