Just as how the Human race utilize Qi to strengthen themselves, the Yinyue race also use something similar to give them power.
In theory, Qi is the air we breath except, in this world however, this 'air' can be used to increase humans power and give birth to prodigies and geniuses.
There is also something else the humans use to give them power. They call it the Endless Dao.
The Endless Dao is a power spread throughout the entire Blue Domain. However, only the human race can grasp it and turn it into power.
The Endless Dao isn't just some sort of power, its a will. A will that develop humans minds and sharpen their resolves.
In the case of the Yinyue race they use an energy they like to call Endless Notes to bring out their power. Only the Yinyue race can sense these notes since they were created from Goddess Yinyue who sang infinite amount of songs to the point they gave birth to spiritual notes made from those songs that are then spread throughout the entire galaxy, especially the Blue Domain.
The only thing the Endless Dao and the Endless Notes have in common however, is the fact that they are unending meanwhile, the difference between them is that the Endless Notes were creating from a god while the Endless Dao was created from the universe itself.
There is also one more difference. The Endless Dao is a power that can only be burrowed. Since it was birthed by the universe the only one they will follow is the universe itself.
The Endless Notes however, have no such restrictions. In fact, anyone from the Yinyue Race could create their own Note which is known as the Notes of Emotions.
Only a few individuals in the entire Yinyue race were able to comprehend this due to the fact that it depends heavily on the person to make one emotion their main emotion.
What this mean is that the person must mainly display one emotion over the others.
In the case of Yu Bing, she usually lacks emotion. So her note would be the Note of Detachment.
Yu Huan would be the Note of Apathetic.
Yu Jing would be the Note of Gentleness.
Yu Yingzi would be the Note of Ruthlessness.
And Yu Yaojing would be the Note of Bloodlust.
These notes follows a person and bind themselves to their users who only display one emotion.
However, if one of them were to ever stop displaying that emotion their Notes of Emotions would start lacking or more likely to say, weaken.
Just like how Yu Bing began laughing, her Note have already started wavering.
As for Yu Yaojing whose being displaying multiply different emotions since she became the Mistress its hard to say if she still has control over her note.
"The Note of Indifference? Isn't that the note the Ancestor used?" Yu Huan exclaimed, utterly shocked. "I thought the Notes of Emotion only followed one user!"
Yu Yingzi became aghast, her mouth left wide open. Yu Huan simply nodded her head while Yu Yaojing smiled foolishly. "Haha! all that is needed is for him to obtain an Ancient Mark and my son will become a true prodigy!" Yu Yaojing laughed, delighted that all her efforts in birthing Yu Sheng didn't go to waste.
"But how did he get the approval of the Notes of Emotions?" Curious, Yu Huan asked.
"Now that was what shocked me. The moment he began playing music is the moment his fate changed. He became cold and indifferent and hardly spoke a single word, only to his parents would he show some emotion." Yu Bing recalled.
"This led to the Note of Indifference accepting him." She finished.
"You said he began developing it. Does that mean he wasn't directly accepted by the Note of Indifference?" Yu Jing questioned again.
Yu Bing explained, "I believe that is because our Goddess Yinyue songs did not fully manage to reach the Domain Little Sheng is from. So only a few fragments of her songs actually got there which led to Little Sheng unable to comprehend the Note of Indifference fully."
Yu Huan then looked at Yu Bing and said, "But still, he lived for 60 years and from what you said he began practicing music at the age of 5 leaving him a total of 55 years to fully comprehend the Note of Indifference."
"So how did he not fully comprehend it?"
"That's the funny part." Yu Bing chuckled at Yu Huan question before telling everyone, "Little Sheng fell in love with a girl."
"Her name was Yin Qing'er. He first met her in one of his music competitions and ever since then he became obsessed with challenging her to 'music battles' until that obsession turned into love. Unfortunately, she became a cripple a couple years after they met."
"And you want to know the funny part?" Yu Bing yawned, feeling tired of using her mouth so much.
"What?" They asked in union.
"This girl died to a disease that caused her to become a cripple."
Everyone expression turn dark after hearing that. "How is that funny?" Yu Jing whispered to herself, but everyone heard her.
Yu Bing chuckled. "Well, that's because she reincarnated here as well, just a couple years before Little Sheng."
Everyone looked at Yu Bing, shocked at what they heard.
"Double reincarnation? To the same Domain? And they know each other?" Yu Huan mumbled questions to herself.
Putting things together Yu Huan said. "Only the gods can reincarnate someone to another plain. But why would they do that? Is it because...."
"Don't say a word!" Yu Bing suddenly shouted, her hands covering Yu Huan mouth. "This information is clearly something the gods don't want us to know. So if you say anything to any of us you don't know how all of us will die!" Yu Bing reprimanded with a cold stare.
"Furthermore, although the gods may be omnipotent beings they are restricted by laws created by the universe so there is no way they would reincarnate two people from the same world to ours in such little time just because they pity them."
"Okay, calm down Yu Bing. Isn't your note the Note of Detachment? Why have you become so alert and scared?" Yu Yaojing pulled Yu Bing away from Yu Huan while she teased her.
Hearing Yu Yaojing voice filled with sarcasm, Yu Bing calmed down. Returning to herself before saying, "Anyways that is all I will tell you. If you want to hear anything else about Little Sheng previous life then you can ask him yourself when he grows up." She exclaim before she turn around and left.
Seeing her walking away Yu Jing touched her shoulder. "Where are you going?" She asked.
"Do I need to tell you where I am going? Your not our mother." Yu Bing shook off Yu Jing hand, feeling annoyed.
"But mother left me to take responsibility over our family."
"And?"
"She also said that you and Yingzi must listen to me...."
Remembering her mother last parting words to them before she died, her eyes showed a rare gentleness as she said softly, "I am going to the Witch Race to obtain the Mind Enhancing potion. I will be back in about 3 months." She said before disappearing into the wind.
Seeing her leave without saying goodbye Yu Jing felt quite irritated by her attitude. "So what will we do now?" She turned to the rest who were planning to leave.
"Have you forgotten that I have a child to take care of?" Yu Yaojing said before entering back the mansion.
"I think Yu Wei is crying." Yu Huan hurried into the mansion as well.
Yu Jing seeing them leaving had an ugly expression on her face. 'Like hell you guys have anything to do!'
She looked at the last person who was left. She opened her mouth, but then closed it back. Yu Yingzi already vanished leaving a single note saying, 'Yu Mei seems to have awaken her Birth Mark.'
Looking at the note Yu Jing silently stood there. Her eyes blazing with anger that wanted to be released. "Even you Yingzi is making up excuses to not hang out with your older sister!" She cursed, but soon she turn her head to the sounds of strange music.
The music spread all over the Yinyue Race. Even travelling towards the Human Race and the Elf Race.
"No way! Did she awaken a Ancient Birth Mark!" Yu Jing yelled in surprise before sprinting towards the direction the music is coming from.
The next day Yu Yingzi brought Yu Mei to the mansion and everyone surrounded her as they stare intently at her.
Even Yu Sheng was there and he stared at Yu Mei with great jealously. "When will my Birth Mark awaken!" He cried out.
Yu Mei birth mark wasn't actually a music note. Instead it was a black infinity sign that has tiny specks of little music notes of different colors coming out of it.
Yu Mei hearing Yu Sheng cry started crawling towards him while she giggle. Placing her hands on his face while knocking her head softly on his.
"What the....." Yu Sheng felt speechless. 'Since when did I become a magnetic for children?! Is this a curse for not properly taking care of my own children in my previous life!' He thought.
Looking at Yu Mei playful expression and then at Yu Sheng expression that was filled with dread everyone chuckled.
They were glad that Yu Mei and Yu Wei are attracted to Yu Sheng since if that wasn't the case then it would be hard for them to form any sort of relationship with one another when they grow up.
"Anyone knows what her ancient mark is called?" Yu Yingzi asked, excited that her child awaken an Ancient Mark.
"This should be the Infinite Mark." After examining Yu Mei for a while, Yu Huan answered.
"The Infinite Mark?" Yu Yingzi question in confusion. She never heard of such a mark before.
"Yes, this mark will allow Little Mei to play a Battle Songs for however long she likes." Hearing this Yu Yingzi became even more excited.
Battle Songs are known as notes. For example, One note song. Two note song, etc.
The more notes that are used, the more intense the battle song can become.
The strongest battle songs are the ten notes. This battle songs are able to release waves of mental attacks every two note.
However, Yu Mei with her Birth Mark allows her to release an endless amount of Notes.
The only disadvantage this mark has is the amount of mental power it will consume. One must know that every 2 notes take up about 1% of one's mental power, depending on the user.
So at most Yu Mei will only be able to use 200 notes before her mental power tank has all been used.
Still, to be able to release 200 notes a day is an achievement that not even the ancestor was able to accomplish.
However, if one reaches their mind power limit then they are at risk of having an headache that could LITERALLY split their brains.
"How does her Birth Mark compare to Yu Wei's?" Yu Yingzi suddenly asked with burning curiosity.
Yu Huan raised an eyebrow at her question before saying, "Little Wei birth mark is most likely also an Ancient Mark. However, from the looks of it, it seems to be more like an Weapon Mark so I cannot really determine how strong it is."
"If mother was here then maybe she could explain it to you."
Yu Yingzi nodded, staring at Yu Mei with pride. 'To think I would be able to give birth to a child with the Ancient Mark.' She thought with a bit of envy. She always wished to be born with an Ancient Mark. Alas, the only thing she could do was blame was her talent.
She then looked at Yu Yaojing with a serious face. "Mistress...."
"It's Queen Yaojing! Queen! QUEEN!!!"
Yu Yaojing turned towards Yu Yingzi and yelled. Repeating the word 'queen' as if trying to sink it into everyone mind that she is in fact, a Queen.
After she was finished she touched her forehead with a frustrated look. "No one seems to respect me..." She mumbled.
Startled by her reaction Yu Yingzi said, "Er... My Queen, I have a request."
"You may speak." Yu Yaojing face filled with frustration suddenly turn bright like the stars as she put on a pleased smile, getting Yu Sheng to chuckle while making Yu Huan and Yu Jing eyes twitch.
As for Yu Yingzi her expression was nonchalant as she said, "I will like Yu Mei to become Prince Sheng bride."
