Cai immediately said, "Of course it's no problem. I'll call them over right away."

While waiting for someone to come, Su Liuyue searched Wei Chuze's room carefully, but did not find any useful clues.

Soon, Cai came over with a servant and two maids. Wei Chuze had more than this many servants around him, but these three were the ones who were closest to him.

Su Liuyue looked at them and said, "I heard that Young Master Wei has been worrying about what gift to give to his third cousin, the Princess of Chu?"

The maid standing on the far left seemed to be more capable of handling matters. She nodded and said, "Yes, young master... had been worrying about this matter for nearly half a month before he disappeared."

"Did Young Master Wei also worry about Princess Chu's birthday?"

"That's not the case either."

The maid pursed her lips and said, "Our young master has a very good relationship with the Princess of Chu, just like real siblings. In the past two years, due to the turbulent times, the young master and the Princess of Chu were almost separated from each other. The young master could not participate in the Princess of Chu's birthday. Therefore, I guess that the young master attaches so much importance to the Princess of Chu's birthday this year.

In addition, the young master has often said that the Princess of Chu doesn’t look very happy recently, and he wants to make her happy…”

Not very happy?
Su Liuyue frowned slightly, "Why is Princess Chu unhappy?"

The maid bit her lip in embarrassment. "We don't know about this. Young Master didn't elaborate, and we didn't ask much. To be honest, we think the Princess of Chu is no different from before. Maybe this is just Young Master's illusion. Or maybe, because Young Master has a good relationship with Princess of Chu, he is more sensitive to her emotional changes..."

Su Liuyue looked at them thoughtfully and said, "How thoughtful is your young master?"

The maid's eyes slightly reddened, and she nodded, "Young Master has been very thoughtful and kind since he was a child. He can tell immediately if we are troubled by something, and he will try his best to help us as long as he can.

To be honest, this young master is the best master I have ever served."

As she spoke, the other two servants sighed sadly.

Su Liuyue asked them a few more questions and then let them leave.

Before leaving Wei Chuze's courtyard, she called Cai and asked, "Do you also think that Princess Chu is in a bad mood recently?"

Cai was slightly stunned, then shook her head and said, "I don't feel that way. Xier has always been gentle and sentimental since she was a child. Sometimes when she sees the flowers in the yard wither, she will be sad for a while. She seems to be talking less than before during this period. But now is late autumn when everything is gradually bleak. In the past, Xier would be more melancholy than usual during this period."

Su Liuyue nodded and said, "Could you trouble Madam Cai to help me find out what's troubling Princess Chu recently when she's calmer? I wanted to ask her in person, but Princess Chu just lost control of her emotions, and I'm worried that if I ask her now, she won't be in the mood to answer me."

Although Cai Shi didn't understand how this matter was related to the case, she still agreed, "No problem, Xi'er should stay at home for a few days, I will find a chance to ask for your majesty."

After leaving the Wei family, Yang Shaoyin couldn't help but ask, "Does Su Xiaolangjun think that the Princess of Chu is really related to Wei Xiaolangjun's disappearance?"

Su Liuyue was silent for a moment, but just said: "It should be related. I have a guess in my mind now, but it needs further confirmation. Next, let's go to the Sun family."

Yang Shaoyin looked embarrassed. After a while, he sighed and said, "The Sun family is quite emotional right now. Young Master Su should be mentally prepared."

Indeed, compared to other families whose children were already confirmed dead, the Sun family still had a glimmer of hope. Now, it was the Sun family that was putting the most pressure on the various government offices.

Su Liuyue has been solving cases for so many years and has seen many unruly and out-of-control family members. However, when she saw the head of the Sun family, Sun Zaiyan, who came out in person to greet them, she was still slightly stunned.

Sun Zai Yan is the father of the missing Sun Heng, who is his youngest son.

He was very tall, with a long face, and he looked very serious. All the muscles in his body seemed to be tense, giving people an indescribable feeling of oppression.

He walked straight to Su Liuyue, glanced at them sharply, and finally fixed his eyes on Su Liuyue. He bowed and said in a deep voice: "I have heard that the Crown Princess has taken over this case. I would like to meet the Crown Princess."

Su Liuyue raised her eyebrows slightly, "Empress Sun actually recognized me?"

"Of course I recognize it."

Sun Zaiyan said, "After the Crown Princess and His Royal Highness got engaged, His Majesty had someone paint a portrait of the Crown Princess. I have been serving His Majesty for many years and happened to see it."

As he spoke, his hawk-like eyes stared at her without blinking.

Su Liuyue looked back at him indifferently.

This guy, what he said sounded normal, but his tone was like a mountain pressing down on people's hearts.

It was as if he was emphasizing to her that although she was the Crown Princess, he was also a close minister to the Emperor.

If she couldn't find out anything about this case, he would also be able to report her.

"I see."

Su Liuyue nodded and said, "I came here today just to ask a few questions. I heard that on the day that Young Master Sun disappeared, he did not do well in the test at the Imperial College, and that was why Attendant Sun beat him up?"

Sun Zaiyan's face became even uglier, and he clenched his fists so tightly that veins popped out. "Yes, this kid is not as talented as his brothers in studying, but at least he always got B or above in previous tests. Who would have thought that this time, he got C-low. Not to mention his brothers, he himself has never gotten such a bad score before! If a son is not taught well, it is the fault of his father. I beat him because I, as a father, care about him!"

Su Liuyue couldn't help but frown slightly, but soon relaxed her brows and asked, "Did Young Master Sun not perform well this time?"

"How should I know?"

Sun Zaiyan gritted his teeth, his eyes slowly turned red, and he spoke as if he was squeezing out words from between his teeth: "I was originally thinking of swallowing my pride and inviting a doctor from the Imperial College to come home and help him with his studies, but who would have thought that this brat... this brat would just turn around and run away..."

"Master, who are you calling a brat? My Heng'er has been working very hard. If you despise my Heng'er so much, you might as well despise me as his mother as well!"

A female voice with a crying tone suddenly came from outside.

Everyone was startled, and saw a woman with a pale face, almost being carried by a group of maids, coming towards them. Although she had no strength left, she still gritted her teeth and refuted loudly. (End of this chapter)
