The Cheng sisters, caught up in their excitement, failed to notice Qin Mu's intentions. They believed he was genuinely helping them; otherwise, why wouldn't he keep such a fine musical score to pass on to his family?

However, the Cheng sisters were not unreasonable people. After the score was completed, the first copy would still be returned to the Qin family.

After the Cheng family left, the other onlookers were filled with anticipation, imagining Cheng Zhijie weeping bitterly. Only Qin Mu felt more melancholy, as if he had done all the work for someone else.

"Don't be sad, maybe none of these are right for you!" Princess Changning gently comforted her.

Musical scores are all about the harmony between the listener and the music, and Qin Mu could only console himself with that thought. He nodded slightly and smiled, saying, "It's alright, I don't mind. If you want sheet music, I have even better ones here."

"Really? Huai Dao, you're amazing!" Princess Changning exclaimed in surprise.

"Of course! The best suona piece, 'Hundred Birds Paying Homage to the Phoenix'! Once I've finished it, I'll give it to our daughter!" Qin Mu approached Princess Changning, gently nudged her, and whispered.

"Pah! Who...who wants to have a daughter for you?" Princess Changning blushed and glanced around guiltily.

"It's fine! My son is fine too," Qin Mu said nonchalantly.

"Then you'd better grow up quickly so you can marry me." Princess Changning felt a sweet warmth in her heart and glanced at Qin Mu as she spoke.

“You’ve grown up! You know that.” Qin Mu deliberately glanced down and said.

"Pah! You scoundrel." Princess Changning noticed his gaze. The two were often seen cuddling together, so she knew what he meant and became even more shy. She quickly moved aside to listen to Yuchi Baolin and the others chatting.

"Baolin, do you really want to marry both Cheng sisters at the same time? That's no easy feat!" Ma Zhou, who was usually very serious, made a rare joke.

"Huh! What did you say?" Yu Chi Baolin, who had just wiped his face, was completely bewildered.

"Didn't you fall for Sister Cheng again?" Xiangli Yanran asked, her big eyes blinking.

"How could that be!" Yu Chi Baolin almost jumped up in fright. He glanced around guiltily, convinced that if he really had that thought, Cheng Huaimo would fight him to the death.

"Then why were you crying so sadly in front of Sister Cheng?" Xiangli Yanran asked, puzzled. The others knew it was a joke, but the little girl thought it must be true.

"Little girl, don't talk nonsense. It's your brother Qin who composed the good music! Do you understand?" Yu Chi Baolin looked fearful and almost covered Xiangli Yanran's mouth. He carefully lowered his head and said.

"Oh!" Xiangli Yanran nodded without saying anything more, which made Yuchi Baolin breathe a sigh of relief.

Qin Mu didn't join in the fun. He was still thinking about why his use of the musical scores had no effect. He didn't believe it was a compatibility issue. He had dug out these scores himself, and in this world, they should belong to his own creations, so there shouldn't be a compatibility problem.

"No talent in this area?" Qin Mu found another reason. He remembered that Qin Yue had said that insight was very important.

"If you need anything, ask your master!" Qin Mu left the Six Doors and went to Li Gang's house. Now that Ma Zhou and Han Chen were in charge of the Six Doors, everyone felt much more relaxed.

Ma Zhou handled the filing, Han Chen handled the investigation, and Yu Chi Baolin and Cheng Huaimo handled the arrests; but the happiest person was Li Chongyi, because most of the case analysis fell to him.

At his request, Qin Mu transcribed the Record of Injustice Rectified from memory. Li Chongyi treasured it greatly, and Han Chen was also very interested in it. The two are currently studying it.

"Compatibility is a minor issue, and talent isn't the most important thing either. Even if someone has poor talent, it doesn't mean they can't use it. It's about understanding the artistic conception! Only by understanding the artistic conception of the score can its power be brought out. The deeper the understanding, the greater the power. This is why only the original composer can bring out the greatest power of any score."

"The reason you're having this problem is that you haven't grasped the meaning behind the musical score." Li Gang quickly gave his answer after hearing Qin Mu's question.

Qin Mu was not very satisfied with this answer. He knew very well the meaning of the "Blue Sea Tide Song" and the "Sacrificial Tune," and he had tried to understand it, but the effect was still not there.

“How about this! Of the four arts—music, chess, calligraphy, and painting—if you want to get started and comprehend the Dao, music and painting are the easiest to begin with. Why don’t you try painting?” Li Gang suggested.

"Please give me your guidance, teacher," Qin Mu asked respectfully.

Li Gang didn't say anything, but asked Qin Mu to tidy up the desk and spread out the Xuan paper.

"When painting, concentrate your mind and focus your attention on the painting," Li Gang advised as he began to paint. With an ordinary brush and simple strokes, a wolf painting quickly appeared.

On the lush green grassland, a lone wolf walks forward, its front paws raised, its sharp eyes fixed on the front, as if it wants to devour someone.

Qin Mu glanced at it once, and his heart tightened. He involuntarily took a step back, clenched his fists, and looked ahead warily.

"I'm only using basic techniques for painting, focusing on capturing the spirit. Do you understand?" Li Gang asked with a smile.

"Phew!" Qin Mu exhaled and concentrated, finally seeing clearly that the paper depicted a lifelike wolf, with its eyes and fur clearly visible.

"Disciple understands!" Qin Mu nodded heavily.

"Why don't you give it a try? Draw something you've actually seen with your own eyes," Li Gang said, pointing to the table.

Qin Mu walked to the spot where Li Gang had just stood, racking his brain for what he needed to draw. After a moment's thought, he began to put pen to paper.

He painted the dinosaur-like monster he encountered in Chang'an. In his painting, the dinosaur stared ahead with its big eyes, claws raised, and a long tail trailing behind. Behind the dinosaur was a forest, and in front of it were many figures, one of whom was holding a long spear and charging forward.

It is no exaggeration to describe Qin Mu's painting as lifelike. Not only are the monsters depicted clearly, but anyone familiar with the figure can recognize it as Qin Qiong. The smaller soldiers are also exactly the same as real people in terms of clothing and weapons.

This was the image in Qin Mu's mind; to his memory, it was indistinguishable from a copy, so it looked exactly like a photograph. If Li Gang knew what a photographic painting was...

“Not bad! Very well drawn. This must be something you personally experienced! But do you know why there’s no special effect?” Li Gang stroked his beard and praised, then looked up and asked.

This is also what Qin Mu doesn't understand. He can paint lifelike things, but he doesn't have any special effects. Generally speaking, paintings that are at the beginner level of painting can already conjure up a mental attack, just like Li Gang's Lone Wolf painting. Once activated, the Lone Wolf can attack the opponent.
