Bai Di remembered the most clearly one time when a group of human bandits who had tried to rob her had ulterior motives. Although Bai Di eventually killed them all, the gruesome scenes she witnessed in their lair, like a clap of thunder, shattered her understanding of the world.
Of course, the kind side of Bai Di also saw a woman with a child. Even though she herself was hungry, she shared her meager rations with Bai Di. Later, when they encountered robbers, Bai Di successfully protected the woman and child. However, in the prevailing environment, the woman and her child's fate was sealed. Bai Di could protect them for a while but not for a lifetime.
Order collapsed, and evil prevailed. The ugly side of humanity was exposed, and those with kind hearts died one after another at the hands of the wicked.
From then on, Bai Di had been contemplating a question: were humans of this kind still worth protecting?
Seeing the bewildered Bai Di, Bai Qi patted her shoulder and pulled her into his arms. "Child, everyone has a dark and evil side within them. It's something no one can avoid. It is precisely because evil exists that goodness is beautiful. Where there is light, there will always be darkness, and conversely, without darkness, how can there be light?"
Seeing Bai Di looking confused, Bai Qi continued to explain, "Child, do you know about Yin and Yang?"
Bai Di nodded and said, "Yes, our main world was formed through the intertwining and struggle of Yin and Yang."
"Precisely. The world is formed by the interaction of Yin and Yang, and so are living beings. They call the good side Yang and the evil side Yin. The two complement each other and are inseparable."
"Does that mean we represent evil?"
Bai Di knew very well that her father was born from black qi and represented Yin. So, according to her father, were they evil?
Bai Qi shook his head and said, "Not exactly. Yang representing good and Yin representing evil is merely a superficial understanding of Yin and Yang by human mages. Their existence is more like a state that maintains the balance of all beings. When one side is amplified infinitely, completely suppressing or even eradicating the other, the world will head towards destruction, and beings will move towards annihilation."
"Then what should we do? Or what role should we play in this world?"
Bai Qi did not answer immediately, but instead asked, "What role do you think we should play in the main world?"
After a moment of thought, Bai Di replied, "We were born from black qi, and our power comes from black qi. Of course, we should stand with Grandma Black Qi and firmly oppose righteous qi."
Upon hearing the term "Grandma Black Qi," Bai Qi couldn't help but laugh.
Seeing Bai Qi's reaction, Bai Di said indignantly, "What's wrong? Did I say something incorrect? You call yourself Mother Black Qi, and I am your child, so naturally, I would call her Grandma Black Qi."
Bai Qi wiped away tears from his laughter. "You're wise beyond your years. You're right. We were born from black qi, so by rights, we should stand firmly with black qi. But you also mentioned 'Grandma Black Qi.' If there's a grandma, who is the grandpa?"
At Bai Qi's words, Bai Di froze, falling into thought. According to human families, where there's a mother, there's a father; where there's a grandma, there's a grandpa. But she had never heard that Grandma Black Qi had an old partner. Could it be that...
After a period of contemplation, Bai Di arrived at a startling conclusion.
"Could it be that Grandma Black Qi's partner is dead?"
"This..."
As soon as Bai Di spoke, Bai Qi was speechless for a long time, and then burst into laughter again.
"Who told you that Black Qi's partner is dead?"
"Isn't he?"
Bai Di tilted her head, her expression filled with wisdom.
"Of course not," Bai Qi explained. "Black Qi's partner is righteous qi."
"What?" Now Bai Di was even more confused, looking as if she were thinking, "You're trying to fool me because I'm uneducated." She muttered to herself, "So, righteous qi is my grandpa, my father's father?"
Bai Qi nodded. "Did you expect that? Are you surprised?"
"I am indeed surprised."
Bai Qi continued to explain, "Originally, the main world did not exist; everything was chaos. Until the arrival of black qi and righteous qi. They were very mysterious, and no one knew where they were born or where they came from. All that is known is that their arrival brought vitality to the main world. Through their union, it gradually evolved, forming the current state of the main world."
Seeing that Bai Di still didn't understand, Bai Qi switched to a more colloquial explanation.
"You can think of righteous qi and black qi as a newlywed couple. Then, they jointly built a cozy little home, which is now the main world. Although there were occasional squabbles, their lives got better day by day."
"And then?"
Bai Qi had never told Bai Di stories before. For the first time, Bai Di, engrossed in the tale, was eager to know what happened next.
"Later, their lives became better and better. This loving couple even conceived the crystallization of their love."
At this point, Bai Di suddenly interrupted, "But Grandma Black Qi and Grandpa Righteous Qi's relationship isn't good now."
"Yes, emotions are very subtle. When they are good, they are inseparable, but when they are bad, they are like a tempest. As their children grew up, problems followed."
"What problems?"
"Perhaps it was the seven-year itch. This couple faced constant troubles. Their children began to fight over toys, even resorting to fisticuffs, and this atmosphere indirectly affected their parents. To resolve the issue, the couple came up with a good idea."
"What idea?"
"The couple began to take sides, passing on their respective powers to the children they favored. Through the children's struggles, they would decide their own standing in the family."
"What kind of parents are they?"
Bai Di pouted disagreeably.
Bai Qi chuckled and said, "This is just a metaphor to help you understand better. Do you want to continue listening?"
"Yes, yes."
"After receiving their parents' power and help, these two children began to fight. Sometimes the older brother won, and sometimes the younger brother won. The family's authority shifted with the victories and defeats of the two children, and the family, under this virtuous cycle, became better and better. However, later, the older brother, in order to end the struggle with his younger brother and monopolize all the toys, used some means to imprison the younger brother in the basement. The mother, who supported the younger brother, also lost her power due to her son's defeat."
