With a loud bang, Ying Yuan was pushed back several steps, and the black shadow revealed its true form.

It was a mysterious man wearing black clothes and a bamboo hat, holding a strange weapon in his hand, shaped like a huge sickle.

"Who are you?" Ying Yuan asked in a deep voice.

The mysterious man did not answer, but swung the sickle in his hand again and attacked Ying Yuan.

Ying Yuan did not dare to be careless and quickly punched to block.

The two fought back and forth. The mysterious man was very powerful, and Ying Yuan gradually fell into a disadvantage.

"Your Majesty, let me help you!" Seeing this, Shao Siming quickly joined the battle.

However, even when the two joined forces, they could hardly resist the attack of the mysterious man.

At this moment, the Moon Goddess suddenly took action, and a powerful yin and yang force attacked the mysterious man.

The mysterious man was caught off guard and was hit by the power of yin and yang, and he staggered back.

"Moon Goddess, thank you!" Ying Yuan said gratefully.

The Moon Goddess nodded, then waved the Yin-Yang Staff again, and streams of Yin-Yang power attacked the mysterious man.

The mysterious man was suppressed by the Moon Goddess' attack and gradually lost his strength.

"Retreat!" the mysterious man suddenly shouted, then turned and ran away.

Ying Yuan and others wanted to chase after him, but were blocked by a black mist released by a mysterious man.

"Damn it!" Ying Yuan punched the ground, feeling full of resentment.

Who is the mysterious man? Why does he want to destroy the Yin-Yang family? All of this is a mystery.

"Your Majesty, what should we do now?" Shao Siming asked.

Ying Yuan took a deep breath, calmed down, and said, "Let's go back to Xianyang first. I want to investigate this matter thoroughly!"

The three of them left the burning Yin-Yang family’s residence and flew towards Xianyang.

Along the way, Ying Yuan was in a very heavy mood. The demise of the Yin-Yang family made him feel an unprecedented sense of crisis.

He realized that the enemy he was facing was much more powerful than he had imagined.

After returning to Xianyang, Ying Yuan immediately summoned all his ministers to discuss the matter.

"The Yin-Yang family was destroyed by a mysterious person. This is a serious matter. I suspect that it was Luo Wang's doing!" Ying Yuan said in a deep voice.

"Your Majesty, although Luowang has always had grievances with the Yin-Yang School, they should not have the strength to destroy the Yin-Yang School." Li Si said.

"Yes, Your Majesty, there are so many masters in the Yin-Yang School that even if Luowang sends out all its forces, it may not succeed." Feng Quji also said.

"Then tell me, who could have done it?" Ying Yuan asked.

The ministers looked at each other in silence.

At this moment, Gai Nie suddenly stood up and said, "Your Majesty, I suspect that this matter is related to Donghuang Taiyi."

"Donghuang Taiyi?" Ying Yuan was stunned. "Why does he want to destroy the Yin-Yang family?"

Gai Nie shook his head and said, "I don't know either, but I feel that this matter is too strange."

Ying Yuan pondered for a moment and said, "Gai Nie, what you said makes sense. I will also investigate Donghuang Taiyi carefully."

At this moment, a guard came hurriedly to report: "Your Majesty, General Zhang Han wants to see you!"

"Zhang Han?" Ying Yuan's mind moved, "Let him in!"

Zhang Han walked into the hall, knelt on one knee, and said, "Your Majesty, I have important information to report!"

What kind of information made Zhang Han so anxious? And how did it relate to the demise of the Yin-Yang family?
Zhang Han's face was solemn, and he clasped his fists and said, "Your Majesty, I have found out that Donghuang Taiyi appeared near the Yin-Yang family's residence on the night of their demise."

"Donghuang Taiyi!" Ying Yuan stood up suddenly, his dragon eyes gleaming, "He is indeed related to this matter! Why does he want to destroy the Yin-Yang family? Could it be that the Yin-Yang family has surrendered to the rebels?"

"Your Majesty, I dare not speculate." Zhang Han bowed his head and said, "I am only responsible for reporting the intelligence truthfully."

Gai Nie stepped forward and said, "Your Majesty, Donghuang Taiyi is a mysterious dragon that is hard to find out what he is doing. It may not be easy to find out his purpose." Ying Yuan paced back and forth, thought for a moment, and said, "Pass on my order to closely monitor Donghuang Taiyi's every move. If there is anything unusual, report it immediately!"

"Yes!" Zhang Han took the order and left.

Ying Yuan frowned, his mind full of doubts. What exactly is Donghuang Taiyi's purpose? What impact will the demise of the Yin-Yang family have on the Qin Dynasty?
He felt an invisible pressure coming towards him.

The Xianyang Palace was brightly lit.

Ying Yuan sat alone in the imperial study, holding a scroll of bamboo slips in his hand, but he had no intention of reading.

The scene of the demise of the Yin-Yang School and the mysterious figure of Donghuang Taiyi kept appearing in his mind.

"Donghuang Taiyi..." Ying Yuan murmured to himself, "What exactly do you want to do?"

Suddenly, his heart moved and he thought of a person - the Moon Goddess.

Yue Shen is a master of the Yin-Yang School whose status is second only to Donghuang Taiyi. She knows the situation of the Yin-Yang School very well, and perhaps we can get some clues from her.

"Someone come!" Ying Yuan shouted loudly.

A guard hurried into the imperial study, knelt on one knee, and said, "What do you want, Your Majesty?"

"Call the Moon God to see you!"

"Yes!" The guard took the order and left.

Soon, the Moon Goddess came to the imperial study.

She was wearing a white robe, with a noble and elegant temperament, like a fairy descending to earth.

"Your Majesty, I am the Moon Goddess." The Moon Goddess bowed slightly in salute.

"No need to be polite." Ying Yuan said calmly, "Moon God, I summoned you here this time because I want to ask you something about the Yin-Yang family."

"Your Majesty, please speak."

"Why did the Yin-Yang School fall? Why did Donghuang Taiyi do this?" Ying Yuan asked straight to the point.

The Moon Goddess was silent for a moment, then slowly said, "Your Majesty, I don't know the reason why the Yin-Yang family was destroyed. As for Donghuang Taiyi's intentions, I have no way of guessing."

Ying Yuan looked at the Moon Goddess with sharp eyes, as if he wanted to see through her heart.

"Moon God, do you really know nothing?"

The Moon Goddess raised her head, met Ying Yuan's gaze, and said, "Your Majesty, everything I said is true."

Although Ying Yuan had some doubts in his heart, he had no evidence to prove that Yue Shen was lying.

He pondered for a moment and said, "Okay, I believe you. However, I hope you can help me investigate this matter."

"I obey your command." The Moon Goddess said respectfully.

"Okay, you can leave first." Ying Yuan waved his hand.

The Moon Goddess bowed, then turned and left the imperial study.

Ying Yuan looked at Yue Shen's departing back and thought to himself, "Yue Shen, what are you hiding?"

He had a hunch that the Moon Goddess must know something but was just unwilling to say it.

However, he believed that one day he would find out the truth of the matter.

In the next few days, Ying Yuan handled government affairs while secretly investigating the truth behind the demise of the Yin-Yang Family.

However, he got nothing.

Donghuang Taiyi disappeared without a trace, as if he had evaporated from the face of the earth.

The Moon Goddess also kept her mouth shut and refused to reveal any information.

Ying Yuan was restless, and he felt that a huge conspiracy was quietly brewing. (End of this chapter)
