Wang Jing strode steadily into the secluded and gloomy courtyard. The walls surrounding the courtyard were quite high, their surfaces mottled and bearing the marks of time. Moss grew in the corners, and a few unidentified weeds swayed in the wind, adding to the desolation and lifelessness.

Dr. Qian was sitting at the old, rickety wooden table in the room, staring blankly at a yellowed medical book. Hearing footsteps outside, his body stiffened abruptly, and he slowly raised his head, his eyes filled with fear and unease.

Wang Jing pushed open the door, a faint smile on his face, but his eyes exuded an irresistible pressure. His gaze swept around the room, finally landing on Doctor Qian, and he said, "Doctor Qian, it's been a long time."

Doctor Qian hurriedly stood up and replied in a trembling voice, "Young master, what brings you here?"

Wang Jing chuckled softly and slowly approached, his finger seemingly tracing the medical book on the table: "I've come today to ask you for a favor."

A sense of foreboding welled up in Doctor Qian's heart, and he subconsciously took a step back: "Young master, please speak plainly."

Wang Jing stopped and stared intently into Doctor Qian's eyes: "I need you to make me a poison that is slow-acting, difficult to detect when it takes effect, but still lethal."

Doctor Qian's eyes widened, and he shook his head desperately: "No, no! Although I have some knowledge of medicine and pharmacology, I absolutely cannot do something as heinous as making poison!"

Wang Jing's face turned cold, and his eyes instantly sharpened: "Dr. Qian, don't forget your current situation. If you don't agree, do you think you can still sit here peacefully studying your medical books?"

Dr. Qian's body began to tremble uncontrollably, and fine beads of sweat appeared on his forehead. He knew in his heart that Wang Jing was ruthless and did what he said he would do.

Seeing that Doctor Qian was wavering, Wang Jing softened his tone slightly: "Doctor Qian, don't worry, as long as you help me with this, I will ensure you have enough to eat and wear for the rest of your life, and I will also give you enough money to go far away."

Dr. Qian was torn between his moral principles and the looming threat of reality. After a long silence, he lowered his head and said in a barely audible voice, "Alright... I promise you."

Wang Jing smiled with satisfaction: "That's right, Dr. Qian. I trust your medical skills, and I hope you won't try anything funny." After saying that, he gave Dr. Qian a deep look, turned around and left the courtyard.

Dr. Qian stood alone in the room, gazing in the direction Wang Jing had left, his eyes filled with regret and helplessness. He knew he was about to fall into an abyss of sin, but there was no turning back.

Dr. Qian sat alone in the dimly lit room, the table in front of him filled with various medicinal herbs and tools. His hands trembled, his heart filled with struggle and fear, but Wang Jing's threat was ever-present, forcing him to take this sinful step.

He took a deep breath, picked up an aconite root, and examined it closely. The root was black, twisted in shape, and emitted a faint bitter smell. Doctor Qian, with his superb medical skills, knew its toxicity was potent, but to meet Wang Jing's demands, he had to use it as the main ingredient in a poison. He carefully washed the aconite, placed it in a stone mortar, and began to crush it vigorously. Each pounding felt like a blow to his own heart; the mortar emitted a dull thud, and as the medicinal juice seeped out, a pungent odor filled the air.

Then, he picked up the datura flower. The flower was pure white and beautiful, but it concealed a deadly danger. Doctor Qian gently plucked a petal, placed it in a small porcelain bowl, and ground it into a fine powder using a special tool. The datura powder emitted an eerie glow in the bowl. A hint of reluctance flickered in his eyes, but he was now in a difficult position.

After processing the aconite and datura flowers, Doctor Qian selected several auxiliary medicinal materials, such as pinellia and arisaema. These materials were also toxic, but through his careful processing, their toxicity was further enhanced and neutralized. He mixed the various herbal powders together in precise proportions, then added some specially prepared medicinal liquid, stirring slowly with bamboo chopsticks. As stirring continued, the powders gradually coalesced into a thick, black paste, emitting a nauseating odor.

Dr. Qian knew that the poison's potency lay in its slow-acting nature. Once inside the body, it would gradually erode the internal organs, disrupting the flow of qi and blood and the conduction of meridians. Initially, it would cause almost no noticeable discomfort, only a slight feeling of fatigue and weakness, easily overlooked. However, over time, the toxicity would gradually accumulate until it finally erupted, causing the poisoned person to die without ever realizing it.

Throughout the entire process, Dr. Qian's forehead was covered in sweat, his hands trembled constantly, and he inwardly condemned his actions. But under Wang Jing's coercion, he had no choice. When the poison was finally completed, he slumped into his chair, staring at the small bottle of poison with empty and desperate eyes, knowing full well that he had committed an unforgivable sin.

A few days later, Wang Jing stepped into that gloomy little courtyard again. The courtyard was eerily quiet this time, with only the rustling of leaves in the breeze.

Hearing footsteps, Dr. Qian slowly emerged from the house. His face was as pale as paper, and his eyes were filled with exhaustion and fear. He clutched the black porcelain bottle containing poison tightly in his hand; the bottle gleamed coldly, as if telling of the deadly power it contained.

Wang Jing's eyes were instantly drawn to the porcelain vase, a glint of greed and excitement flashing in them. He asked eagerly, "Dr. Qian, is the item ready?"

Doctor Qian nodded slightly and said in a hoarse voice, "Young master, the poison has been prepared as you requested. However... this poison is too insidious, and the consequences of its use would be unimaginable." His words carried a hint of admonition, but he also knew he could not change Wang Jing's mind.

Wang Jing sneered, strode forward, snatched the porcelain bottle from Doctor Qian's hand, and examined it closely. The poison inside was dark black, viscous, and emitted a nauseating odor, yet he seemed to see his own conspiracy succeed, and the corners of his mouth involuntarily turned up.

“Dr. Qian, you’ve done a great job. As long as this succeeds, I will keep my promise and keep you safe,” Wang Jing said, but the sinister look in his eyes sent chills down Dr. Qian’s spine.

Doctor Qian lowered his head, his body trembling slightly, and said softly, "Young master, I hope you... will use this poison with caution."

Wang Jing waved his hand impatiently: "You don't need to worry about these things. Just keep your mouth shut. If word gets out, you know what will happen to you."

After saying this, he carefully put the poison into his pocket, turned around, and quickly left the courtyard. Doctor Qian watched his departing figure, his heart filled with regret and despair. He knew that he had been drawn into an irreversible vortex of sin, and that the fate of the Mu family was about to be completely rewritten under the shadow of this poison.
