Ever since Murong Yan moved into the Marquis' Mansion, Uncle Ling's lectures on the four subjects of the Ministry of Revenue also moved to the Mansion.

Steward Shen arranged the lecture hall in the small building in the middle of the lake in the Marquis's garden. The small building had no walls and was supported by columns on all sides. It was originally used for family banquets in the Marquis's garden. It was very spacious and could accommodate more than 20 tables.

The surrounding environment is very elegant. It is not yet midsummer, and there is still a cool breeze, which is set against the sparkling water surface, making it very conducive to teaching and thinking.

The young masters came one after another, and some of them even brought gifts to visit. Butler Shen ordered the servants of the Marquis' Mansion to bring the best tea and snacks to entertain Uncle Ling and a dozen young masters who came to study.

Murong Yan looked at Murong Yao, who was sitting diagonally across from him, and said with displeasure in his gentle voice, "Third brother has also come to the Marquis' Mansion. What a rare guest."

"Royal brother, what you said means that this prince cannot attend Uncle Ling's lectures?" Murong Yao wore a crescent-shaped white brocade robe, embroidered with silver threads and shimmering with light. He held a folding fan in his hand, which he opened with a swish. "This prince loves to listen to Uncle Ling's lectures on history the most."

Murong Yan sneered. Seeing him fanning himself, he taunted him, "Third brother, you're so afraid of heat! A dozen girls and a young servant can't cool you down?"

"You!" Murong Yao rolled his eyes at him and said unconvincedly, "My royal brother also visits brothels, and the laughter is just as great as the laughter of others."

Murong Yan narrowed his eyes. "At least this prince didn't use women's money to visit brothels. Unlike my third brother, he cheated the ladies out of their cosmetics money to visit brothels. How promising~"

"Your Highness the Crown Prince is truly promising." Uncle Ling glared at Murong Yan with a stern face, interrupting their bickering and sternly rebuking him, "You're already a grown man, yet you're still refusing to leave the Marquis' Mansion!"

He then put on a slightly apologetic expression and said politely to Ye Wanqing, "I'm sorry to bother Master Shen for the next few days. When the Marquis comes back, I'll treat him to a drink."

Ye Wanqing smiled politely, "It's no problem. It's a great honor for our humble home that our uncle is willing to come to give lectures."

Murong Yan put his arm around Ye Wanqing and asked her to sit next to him. He said casually, "A Xu also often stays in my East Palace. What's wrong with me staying in the Marquis' Mansion for a few days? Besides, the scenery in the Marquis' Mansion is so beautiful. It would be beneficial for us to gather our ideas."

Uncle Ling frowned, coughed heavily, and motioned everyone to sit down, then he began to talk about the metaphysics of the four departments of the Ministry of Revenue.

Ye Wanqing was very confused by what she heard. They were all topics about morality and ethics, which were extremely profound.

Just as everyone was listening intently to Uncle Ling's explanation of metaphysics, Liu Zhang, the Grand Court Judge, slowly entered the pavilion, carrying a scroll. He bowed to Uncle Ling and the other princes and said, "I heard that Uncle Ling was giving a lecture on metaphysics at the Marquis' Mansion. I rushed here as soon as I finished my shift. It seems I'm late."

Ling Guojiu frowned slightly. He and the Liu family had always been at odds, often exchanging polite insults in court. Seeing Liu Zhang approaching with a book to listen to his lecture, he seemed a little surprised and said unhappily, "Master Liu is so busy with affairs of state, I didn't expect you to be interested in metaphysics."

"Of course." Liu Zhang's expression remained calm. He raised his eyes to look at the guards behind Murong Yao, then glanced at the young masters who were studying there. Finally, his gaze fell on A Rao beside Ye Wanqing, and he said meaningfully, "This humble official believes most in fate."

Uncle Ling said contemptuously, "The Dali Temple Minister can't rely on fate to solve cases."

"Uncle Ling, don't pay attention to me. Just continue teaching." Liu Zhang walked to Murong Yao and sat at the desk opposite Ye Wanqing.

The young man who was originally sitting saw Liu Zhang sitting over and quickly stood up to give his seat to him, and then found an empty seat and sat down.

"Miss opposite," he glanced at the used snacks on the table, the corners of his lips curled up slightly, and he ordered, "Please give me another serving of snacks."

"Prince." A Rao looked at Ye Wanqing, searching for instructions from her eyes.

Ye Wanqing nodded in agreement. A Rao understood and went down to get some tea and snacks, then bent over to place them on his desk and removed the ones that the young man had used.

But Liu Zhang gently pulled her wrist, and A Rao whispered unhappily: "What are you doing?"

He said very politely, "What Uncle Ling said is very profound. I want to copy it down and think about it carefully when I get home. Master Shen, I came here in a hurry and forgot to bring paper and pen. Could you lend me a set of the four treasures of the study?"

When Ye Wanqing saw Liu Zhang asking to borrow a set of pens and ink, she agreed without hesitation and immediately asked A Rao to go to the study to get a set.

After a while, A Rao spread out the brush, ink, paper and inkstone in front of him. Just as she was about to leave, she saw Liu Zhang said again, "Miss, please grind some ink for me."

A Rao patiently knelt beside him, took some water, and lowered her head to grind ink for him.

Liu Zhang supported his head with his hands, and looked at A Rao who was concentrating on grinding ink with a gentle gaze, and did not forget to praise: "Young lady, you are really careful. The ink you grind is really even."

"Lord Liu is here to cause trouble, isn't he?" Liu Zhang's arrival made Uncle Ling's friendly attitude worse, especially since he interrupted his lectures several times, which made him certain that Liu Zhang was here to cause trouble.

Liu Zhang had a gentle smile on his face and apologized, "I'm sorry, Uncle Ling, please continue. I, Liu, should be more careful."

Seeing that he was so humble, Uncle Ling didn't want to start a fight, so he just picked up the book and continued talking.

After a while, Liu Zhang stood up and said, "Master Shen, I would like to use your mansion's restroom for a while, but I'm not familiar with the environment in the mansion. Could you please let this young lady lead me there?"

Ye Wanqing frowned slightly. The Liu Zhang she had met before was always serious and cautious. She didn't expect him to be so troublesome. Was he really here to cause trouble?

But what's the point of destroying such a scene?

Ling Guojiu's face turned stern. He asked, "Master Liu, if you have any suggestions for my teaching, please tell me directly!"

"No, no, the snacks at the Marquis' Mansion are so delicious. I just had too much to eat."

Liu Zhang smiled leisurely. He looked at A Rao who was kneeling beside his desk and said, "Thank you for leading the way, young lady."

A Rao stood up with the help of the table. Because she had been kneeling for a long time and the poison of Baihua Softening Powder had not yet been eliminated, she felt her legs numb. She took a step and stumbled and fell forward.

Liu Zhang quickly stepped forward and held her arm, letting her fall into his arms. A gentle smile appeared on his face, "Are you okay, girl?"

A Rao's face looked a little ugly, but it was not good to show her discomfort in such an occasion, so she patted the wrinkles on her skirt to cover it up, stood up straight, and said in a cold tone: "Master Liu, please come in."

"Thank you."

Murong Yan noticed Liu Zhang's actions. He stroked his chin in confusion and began to think.

Uncle Ling was so disturbed that he lost interest in teaching and simply assigned homework. "Okay, the homework has been assigned. Please go back and think carefully about the answers and hand them in before the next class."

"So, do you have any questions about this class?"

Murong Yao said, "I have heard that the Emperor's uncle is quite knowledgeable in history, so I would like to ask him about some history."

Ling Guojiu checked the time. Due to Liu Zhang's interruption, he had only taught half of the metaphysics class. So he said patiently, "Your Highness, please continue."

"It is a piece of history about the Dongyi people, "Joining the Army in Place of My Father"
