Su Wanti took out the chain left by her father and presented it to Madam An, saying:

"Does Mrs. An recognize this chain?"

Old Madam An squinted her eyes to look at the object in the woman's hand. When she saw the object clearly, her eyes suddenly widened, her lips trembled, and her hands and feet shook constantly.

She felt as if her heart had been hit by a heavy hammer, and she was suffocated and couldn't breathe.

His nostrils shrank sharply, his mouth opened, and a whistling sound came from his throat.

Su Wanti hurriedly patted the old lady's back, and after a few pats, Madam An's breathing returned to normal.

At this moment, Mrs. An's heart was pounding, and her hands were at a loss, dancing in the air frantically, not knowing where to put them.

Her eyes were fixed on the chain, and after a while, she stared at Su Wanti.

It took a long time for Mrs. An's excited heart to calm down. She picked up the chain and looked at it carefully inside and out.

Then he grabbed Su Wanti's sleeves with both hands, tightly grasped them, and said with tears in his eyes:

"This is my little grandson's accessory, which I made for him myself. I chose this pendant for him at Baohuazhai in Beijing. There's a tiny scratch on one of the goldfish's scales. I accidentally scratched it with my fingernail back then..."

"This is the accessory I gave to my grandson, there's no mistake. How did Miss Su get this... Miss Su, you, you are..."

As she spoke, tears flowed uncontrollably. There were small sparks in her misty eyes, and that was the hope rekindled in her heart.

Su Wanti took a deep breath and said softly, "This is what my father left behind. He has had it with him since he was a child."

"Your father..." Madam An's heart was pounding, and her lips trembled uncontrollably. "Where is your father now? What does he look like?"

Her little grandson looks very much like her eldest daughter.

The Miss Su in front of her was pretty and graceful, just like her eldest daughter when she was young.

That's why she was so excited when she saw Miss Su yesterday and almost lost her composure.

Su Wanti's voice was like a gurgling stream, echoing slowly in the quiet room.

"I look very much like my father, especially my eyebrows and eyes."

The spark in Mrs. An's eyes grew bigger.

"A month ago, my father gathered the Resurrection Herb. He saw the reward notice for the An family's medicine and came to Luzhou alone. He mysteriously disappeared on the way and no trace of him was found."

"What?" Old Madam An cried out in grief, completely losing her usual calm and dignified demeanor.

"Madam, what happened?" The nanny guarding the door rushed in.

Mrs. An held Su Wanti's hand tightly, with tears and smiles on her face, a mixture of sadness and joy.

"Old lady..." The nanny was very worried when she saw this scene.

After a while, Madam An wiped away her tears and said, "Let everyone in the An family go out and look for him. I must find your father!"

Her excitement subsided and her mind became clear.

"Good boy, tell me in detail about your father."

It was not until noon that Su Wanti left Madam An's yard, and Madam An stayed with Madam An to serve her mother-in-law lunch.

As soon as Su Wanti walked out of the courtyard, she saw the court doctor sitting on the stone bench in front of the courtyard waiting for her.

"Doctor Su, I'll give you a ride." The court physician stood up, his brows calm and his eyes respectful and polite.

Su Wanti asked, "Doctor Qu, do you have anything to tell me?"

The court doctor's surname was Qu. He smiled slightly and then gestured to invite her in. "Let's talk while we walk."

Su Wanti did not refuse, and the two of them walked together towards Madam An's yard.

The two courtyards are not far apart and can be reached by going around a small garden.

The court doctor first chatted with Su Wanti about some taboos on Madam An's medication, then he sighed and whispered, "Dr. Su is very skilled in Chinese medicine. Even without me telling you, you can tell what's wrong with Madam An."

Su Wanti pursed her lips, said nothing, and just looked at him with clear eyes.

Seeing that she didn't respond, the court doctor had no choice but to confess, "Madam An's illness was caused by poisoning. The imperial physician and I all know this, and the two An masters also know this. It's just that Madam An is very old, so we dare not tell her the truth."

Su Wanti blinked slightly, "You mean that I should also remain silent and not tell Madam An that she was actually poisoned?"

"That's exactly what I meant." said the court doctor.

Su Wanti nodded. "Madam An is nearly eighty years old and can't stand any stimulation. I won't let her know about the poisoning."

"Doctor Qu, the An family is powerful, Minister An holds a high position of authority, and Madam An holds a royal decree. Who poisoned Madam An, and what was her purpose?"

The court doctor's expression was cryptic. "This matter... I, I'm not too sure either."

Su Wanti chuckled, "Doctor Qu has been working for the An family. What could he possibly hide from you?"

She stopped and took out a pharmacopoeia from the medicine box and said:

"My master compiled a pharmacopoeia in his spare time. It records in detail the basic information of various medicinal herbs, their shapes, identification methods, and also states the effects and safe dosage of each herb."

Doctor Qu was a medicine fanatic. After listening to Su Wanti's story, he couldn't wait to take the pharmacopoeia and look through it.

Su Wanti looked at him who was unable to let go of the pharmacopoeia, her eyes flashed slightly and a smile appeared at the corner of her mouth.

In fact, this pharmacopoeia was not compiled by her master, because her master did not have time to compile a book.

This pharmacopoeia was taken from her space. The content of this book is more standardized and scientific than the pharmacopoeia of this small world, and it contains a richer variety of medicinal materials.

"This is just one of the books. If Doctor Qu can tell me the inside story of Madam An's poisoning, I will give you the entire pharmacopoeia." Su Wanti's voice was soft and gentle, like a gentle breeze.

But when her words fell into the ears of Doctor Qu, every word was full of temptation.

"Hmm..." He held the book in his hand, raised it and put it down again, struggling for a long time, and finally made up his mind.

"Okay! I'll tell you everything!"

Su Wanti went to his yard with the court doctor.

This yard is located in the front yard of the An Mansion. Various herbs are drying in the yard. There are rows of Chinese medicine cabinets in the house. Two little medicine boys are grinding and pounding herbs under the eaves.

"Go and have your meal!" the court doctor said to the two little medicine boys.

After the little medicine boy left, the palace doctor said, "It's inconvenient for you and me to be in the same room. Since there's no one here, I'll talk to you here."
