On her wedding night, she went into exile with her pharmacy arsenal

The treatment center immediately became busy, with the doctors performing their respective duties according to Yan Ruyu's plan.

Although new patients are being admitted, their symptoms are effectively controlled because the treatments are appropriate.

Yan Ruyu checked on the patients in the ward, asking about their feelings from time to time and adjusting the dosage of their medication.

About an hour later, Song Ping strode in, his expression somewhat solemn.

"Your Highness, there's important news." Song Ping walked to Yan Ruyu's side and said in a low voice, "The worker who poisoned the clinic has been found!"

Yan Ruyu's eyes lit up: "Where is he? Did you find out anything?"

“The man has been apprehended and is in the outer room,” Song Ping replied. “At first, he was stubborn, saying that he was a shop assistant at the pharmacy and that he only poisoned the medicine in a moment of confusion.”

But just now a patient recognized him, saying he wasn't from the pharmacy at all, but a clerk at a fresh produce shop in the west of the city, and that he'd seen him several times before when buying mushrooms.

"Just as I suspected." Yan Ruyu was completely certain in her heart, and her eyes darkened. "This fresh produce shop is definitely involved."

Just then, Governor Cao also came over, holding the newly compiled interrogation records in his hand: "Your Highness, the preliminary interrogation results are in!"

Over 80% of these patients had bought mushrooms from the fresh produce store in the west of the city, and most of them had also purchased medicinal cuisine from it. Furthermore, they had all consumed alcohol before falling ill!

This result confirmed Yan Ruyu's guess: the medicinal food shop, the fresh produce shop, and the wine were indeed the key to the poisonous scheme.

Yan Ruyu turned to Song Ping and said, "Song Ping, go back to the Prince's residence immediately and report to the Prince. The Prince will make the arrangements."

"Yes!" Song Ping accepted the order and immediately turned to leave.

The air was filled with a faint smell of dust and a barely perceptible stench of blood.

The captured man was tightly bound to a wooden post with thick hemp rope.

Yan Ruyu walked in, followed by Sun Qing.

"So you're the one who poisoned him?" Yan Ruyu walked up to the waiter and stopped, her gaze sweeping over him calmly, her tone revealing neither joy nor anger.

The waiter stiffened his neck, his eyes darting away for a moment, before he said in a firm voice, "I don't know anything about poisoning!"

"You've arrested the wrong person. I'm just an ordinary guy. Why have you tied me up here for no reason?"

Upon hearing this, Yan Ruyu did not say another word, but simply turned her head and gave Sun Qing a faint look.

Sun Qing understood, stepped forward, and without saying a word, raised his hand and slapped the waiter across the face.

"Slap! Slap! Slap!" The crisp sound of slaps rang out one after another in the small room, each one powerful.

Caught off guard, the man's cheek instantly swelled up, and a burning pain spread along his skin.

After a few slaps, his face was swollen like a steamed bun, blood trickled from the corner of his mouth, a loose tooth fell to the ground with a "thud," his mouth was full of the taste of blood, his cheeks were so painful that they were almost numb, and even opening his mouth felt difficult.

"Ah—" he couldn't help but cry out in pain.

Yan Ruyu looked at him, her tone still calm: "Now, can you speak?"

The man, panting heavily, roared incoherently, "You've forced a confession out of me! I didn't do it, I didn't do it, I don't accept this!"

A hint of coldness flashed in Yan Ruyu's eyes, and she raised her hand again and waved it gently.

Seeing this, Sun Qing clenched his fists and punched the waiter hard in the chest and abdomen several times.

The dull thud of a fist landing on flesh was heavy and jarring. The man was violently shaken by the blows, and the rope creaked as it rubbed against the wooden post.

He felt a tightness in his chest, as if his internal organs had shifted, and he felt dizzy and lightheaded, his vision blurring. He almost fainted.

"Still being stubborn?" Sun Qing withdrew his fist and coldly cursed.

Yan Ruyu drew a dagger from her waist. The dagger made a soft "whoosh" sound as it was drawn from its sheath, and gleamed with a cold light under the dim lamplight.

She casually tossed the dagger to Sun Qing, her voice completely flat: "To wake him up."

Sun Qing caught the dagger, flipped his wrist, and plunged it into the waiter's shoulder without hesitation.

With a "thud," the blade pierced through the clothing and penetrated deep into the flesh, causing blood to gush out instantly and stain the waiter's shirt on his shoulder.

"Ah—!" A shrill scream pierced his throat, and the waiter's previously unfocused eyes instantly cleared.

A wave of excruciating pain washed over his body, causing him to tremble uncontrollably. Cold sweat rolled down his forehead and quickly soaked the back of his clothes.

Yan Ruyu spoke slowly, her gaze falling on his pained and contorted face: "Now, can you speak?"

The man was trembling uncontrollably, his teeth chattering, his lips quivering, and his face as pale as paper. All traces of his earlier stubbornness had vanished.

Looking into Yan Ruyu's icy eyes, as if he were seeing the Grim Reaper, he hurriedly nodded: "I...I can talk...I'll talk..."

Sun Qing pulled out his dagger, and the blood on the dagger dripped onto the ground, making a "drip-drip" sound.

He spat and cursed, "You spineless bastard! Wouldn't it have been easier if you'd said this earlier? Hurry up and tell me, or you'll regret it if you utter a single lie or are slow!"

The waiter was in so much pain that he was covered in cold sweat. He gasped for breath and hurriedly said, "I really didn't know it was poison. Our boss made me do it. I didn't want to do it at first, afraid of causing someone to die..."

He swallowed hard and, enduring the excruciating pain, continued, "The shopkeeper told me to take that thing to the treatment center to poison someone. I was scared, so I secretly found a dog to test it on."

The dog was perfectly fine after eating it, so I dared to go.

I thought it would just worsen someone's condition and cause you some trouble, but I never expected it to escalate into such a big problem..."

"What did the dog do to you? Using it as a test subject for poison!" Sun Qing was furious and kicked the wooden pillar again, making the waiter tremble.

Can dogs and people be compared?

Sun Qing cursed, "Those people outside are already seriously ill. If I give them medicine, how can they possibly get better?"

The waiter immediately cried out in distress, "I was really cheated by the manager! I'm innocent!"

Yan Ruyu sneered, her eyes sharp as knives: "You say you were instructed by the shopkeeper, do you have any evidence?"

The waiter's eyes darted around quickly, and his gaze flickered.

Just as he was about to say no, he caught a glimpse of Sun Qing raising his hand holding the dagger again out of the corner of his eye. He trembled with fear and quickly changed his words: "Yes! I have evidence!"

"Speak quickly!" Sun Qing urged, the tip of the dagger flashing in front of his eyes.

"Our shopkeeper is incredibly stingy!"

"Normal times, let alone tips, he often delays even paying his wages!" the waiter said hastily, speaking rapidly. "He has a peculiar habit: he likes to engrave his surname on his silver coins!"

He gave me ten taels of silver as payment for this errand, and his surname was engraved on the silver!
