The bad husband wanted to bring his second wife into the house, so I turned around and became his st

Xiao Cui was intimidated by Lu Shengyuan's aura. She raised her head, her face filled with confusion and helplessness. She just shook her head desperately: "Your Highness, this servant...this servant really doesn't know what you are talking about. The old lady has always been fine, there is nothing unusual."

Upon hearing this, Lu Shengyuan frowned and the displeasure in his eyes became even stronger.

Lin Wanqing gently shook his hand and signaled him with her eyes to be patient.

You won't get anything out of them by forcing them at this point.

Lin Wanqing squatted down and looked Xiao Cui in the eye. Her voice was soft and firm, like a spring breeze: "Xiao Cui, don't be afraid. We are not blaming you. It's just that there are some things that we need your help to figure out."

Xiao Cui looked at Lin Wanqing's clear eyes, and the fear in her heart eased a little.

She nodded and said in a trembling voice, "Princess, I really don't know... The old lady has been fine recently, there's nothing special about her. Her diet and daily life are the same as usual. No one has approached her, and there's nothing special about her."

Lin Wanqing frowned slightly and continued to ask, "Xiao Cui, think carefully about what this old man and the old lady did before they fainted."

Xiao Cui fell into deep thought after hearing this.

After a while, she suddenly raised her head and said, "By the way, the old lady drank a bowl of soup before she fainted."

"Soup?" Lin Wanqing and Lu Shengyuan frowned at the same time.

"Yes, that bowl of soup is what the old lady drinks every day. The ingredients in it have been specially checked by someone, so there must be no problem." Xiao Cui's tone was very affirmative.

After hearing this, Lu Shengyuan became even more suspicious.

The soup we drink every day is the most vulnerable part to tampering.

"Where is that bowl of soup now?" Lu Shengyuan asked in a deep voice.

Xiao Cui pointed to the table outside the room and said, "It's right there. I'll get it right away."

After saying that, she stood up and walked out quickly. After a while, she came back with the bowl of soup.

Lu Shengyuan took the soup bowl and looked at the soup inside carefully.

The soup was clear and there was nothing unusual about it, but the more it was clear, the more doubts he had in his heart.

"Who is responsible for making this bowl of soup?" Lu Shengyuan asked coldly.

Xiao Cui was startled and quickly said, "It's... it's Aunt Liu from the kitchen. She has always been in charge of the old lady's diet."

Lu Shengyuan nodded and handed the bowl of soup to the servant beside him.

"Go find Aunt Liu. I want to ask her in person."

The servant took the soup bowl and was about to turn and leave when Lin Wanqing suddenly said, "Wait a moment."

She looked at Lu Shengyuan and said softly, "Your Highness, I... I know some medical skills. Can you let me take a look at this bowl of soup?"

When Lu Shengyuan heard this, a hint of surprise flashed in his eyes.

He had forgotten that Lin Wanqing had once saved his life, and he must have some knowledge of medical skills.

He nodded and handed the bowl of soup to Lin Wanqing.

Lin Wanqing took the bowl of soup, sniffed it gently, and looked carefully at the color of the soup. Then he frowned slightly and looked solemn.

Seeing this, Lu Shengyuan's heart tightened: "Princess, have you discovered anything?"

Lin Wanqing didn't answer immediately. Instead, she carefully examined the soup again. After a moment, she slowly spoke, "Your Highness, although the color of this soup is clear, if you smell it carefully, you can smell a faint odor. This... this is definitely not an ordinary soup."

Upon hearing this, Lu Shengyuan's face became even gloomier.

He took the soup bowl and sniffed it again, and sure enough, he smelled a subtle peculiar smell.

"Could it be... that this soup was really poisoned?" Lu Shengyuan's voice was low and cold, and every word seemed to be squeezed out from between his teeth.

Lin Wanqing nodded: "It's very likely. Moreover, the person who poisoned her was very cunning, and the poison they used was also very concealed. It would be difficult to detect unless you are familiar with medical skills."

A hint of coldness flashed in Lu Shengyuan's eyes. He gripped the soup bowl tightly, his knuckles turning white from the force.

The atmosphere in the palace suddenly became tense. Lu Shengyuan's voice was like the wind in winter, cold and biting, echoing in every corner.

"Pass the order down, seal off the entire palace immediately, no one is allowed to enter or leave, I want to interrogate Aunt Liu myself." Every word he said seemed to carry a thousand pounds of power, making everyone's heart tremble.

Lin Wanqing stood aside with a complicated look in her eyes. Lu Shengyuan had a deep affection for his mother. Now that his mother was poisoned and unconscious, it was undoubtedly a bombshell in his heart. He would definitely investigate the matter thoroughly and would never tolerate it.

The palace gates were tightly shut, and the servants were gathered together, each with an uneasy look on their faces. Soon, Aunt Liu was brought in by the servants.

As soon as she entered the room, she felt the atmosphere was unusual. Seeing Lu Shengyuan and Lin Wanqing standing there, she couldn't help feeling a little nervous.

"Prince...Prince, Princess, what do you want from me?" Liu Ma's voice was trembling. She pretended to be calm, but the uneasiness in her heart was hard to conceal.

Lu Shengyuan didn't say anything, just stared at Liu Ma coldly.

His gaze was as sharp as a sword. He pointed at the bowl of soup on the table and said in a cold and firm voice, "Auntie Liu, did you make this soup?"

Aunt Liu looked in the direction of Lu Shengyuan's finger, and her heart skipped a beat.

That bowl of soup was made by her, but...but how could there be a problem?

But it was clearly made according to the old lady's instructions, there was absolutely no tampering!

"Yes...I made it." Aunt Liu swallowed, her voice a little dry. "But...but is there anything wrong with it?"

Lin Wanqing raised her head and looked at Aunt Liu, her voice cold and majestic: "Aunt Liu, do you know that this soup has been poisoned?"

When Aunt Liu heard this, her face turned pale instantly.

She raised her head sharply, her eyes filled with horror and disbelief.

"Poisoned? How...how is this possible? I have always served the old lady and the prince and princess loyally, and have never done anything to let the palace down!"

Lin Wanqing looked at Liu Ma's frightened expression and couldn't help but feel a little suspicious.

Did she really not know that the soup was poisoned?

But she had clearly made the soup, how could she not know? Unless… unless someone had tampered with the soup while she was making it.

Thinking of this, a cold light flashed in Lin Wanqing's eyes.

"Auntie Liu, don't panic." Lin Wanqing spoke slowly, her tone revealing an unquestionable majesty. "Think carefully, every time you make this bowl of soup, are there any outsiders present? Or, has anything unusual happened?"

Aunt Liu's hands were shaking as she tried to calm herself down and recall the events carefully.

"Princess, everyone else in the kitchen was present when this soup was being prepared," Auntie Liu's voice trembled slightly. "Besides, it's nothing new that the old lady likes fish soup; the servants all know it."
