This is an excellent book. Gu Bainiang had heard of it.

The Shen family has a peerless and unique concocted pharmacopoeia, which was inadvertently obtained by the ancestor of the Shen family who originally founded the medicine store, but after all, it is an official eunuch's family, and this book is only regarded as a unique book to treasure, and the knowledge in it is not fully utilized.

When she gave the book to the old master of the Shen family's medicine store, the old master was willing to sign and sell herself, not only herself, but also her own children and grandchildren, all of whom became slaves of the Shen family.

There is such a great temptation in a book, but it is from the mouth of this master that there is another book that is more powerful than the Shen family's book.

That is "Liu Gongpao's Seventeen Laws".

Since the Yellow Emperor Neijing first recorded that medicinal materials need to be made into medicine, for thousands of years, the processing of medicinal materials has been slow, the passage is only a simple washing of the soil, remove the non-medicinal parts, there is no strict specification of slicing, cutting, crushing, until the Tang Dynasty, there is a master, in the concoction of medicinal materials is quite profound, summing up the experience of predecessors and their own life practice, wrote a monograph on the preparation of medicinal materials.

This master's surname is Liu, so this book is called Liu Gong Cannon Burning, and because the book summarizes the seventeen methods of medicinal materials concoction, it is commonly known as Liu Gong Cannon Burning Seventeen Methods.

Since the advent of this book, almost no one has seen the real book, it is said that it only exists in the hands of the descendants of Liu Gong, and Liu Gong's skills are passed on alone, several dynasties and generations, Liu Gong's descendants are becoming fewer and fewer, and this book is even more no one has seen, and over time it has become a legend, and then a pharmacist wrote a book made of medicinal materials, that is, the book that the Shen family hid, and it was in that book that this book was mentioned, so that everyone knew that there was really a book of Liu Gong's seventeen methods in the world.

When Gu Bainiang gave the book to the concoction master, she was deeply impressed by the ecstatic appearance of the concoction master, so the conversation at that time was also very deep in her memory.

At this time, the title of the book jumped into her eyes, and she remembered it at once.

"You know your book?" When the old man saw her expression, he raised his eyebrows, a little surprised.

"Are you real or not?" Gu Banniang asked in an astringent voice.

The old man pursed his lips and threw the book to her casually, "Look, look, it's black and white, and it's fake!" ”

Before Gu Banniang could reach out her hand, the old man came back to his senses and grabbed it back, because the movement was too violent, he tore a corner of the book.

Gu Banniang's distressed eyelids jumped, if it was true, this book was priceless.....

"Hey, little girl, look at my medicine....if you recognize it, how about I give you this book?" The old man said with a grin as he shook his book.

"Okay." Gu Bainiang agreed without hesitation.

"Don't be in such a hurry," the old man said with a smile, while he looked at the book again, shook it, and was a little puzzled, "Isn't it just a book, what's so strange....young people are impulsive....impulsiveness is easy to lose..."

The donkey cart was swaying out of the county town in the river, and the young man was attracted by their words and looked back from time to time.

"What do you know, our eldest sister is a scholar, and she loves to read the most, what do you know as a layman!" The young man said with a cocked nose.

"The children of the scholars...."The old man looked at Gu Eighteen Niang with small eyes when he heard this.

"Does my husband have any other requirements?" Gu Bainiang asked.

The old man nodded, rolled his eyes, "If you can't see it, tell me who you are learning from." ”

Gu Bainiang was stunned for a moment, a little funny, "You want to ask who I am taught by?" ”

The old man looked at her profoundly, looking like you couldn't fool me, and snorted with a wrinkled dry nose: "It's the first time I've been recognized by someone so quickly about the medicine I made, so naturally I have to ask for advice..."

Gu Bainiang covered her mouth and smiled, "Uncle, didn't you say that I was too smart?" Why do you think I was taught by a master now? I didn't have a master to teach me..."

The old man sneered, and said earnestly: "Young man, it's good to be smart, but it's not right to lie to people...."

Gu Bainiang wanted to roll her eyes, isn't it right to deceive people? He was also embarrassed to say....

"How? Do you dare to bet? The old man shook his head and said.

That's it? Gu Bainiang covered her mouth and smiled, of course she gambled, she won the treasure book and lost....hahaha, if you lose, you just introduced yourself to this old man, don't they already know each other?

"Bet!" Gu Banniang said with a smile.

"Little girl," the old man was also very happy, with the pride of seeing the loser, and thinking that the atmosphere in this world is not good now, but all pharmacists who have some ability have a strange temper, this little girl refuses to say the teacher's inheritance, but she is afraid that her master is not allowed to say it, if this girl is forced to say, who knows how the strange master will scold.

To receive such a smart apprentice, if he was really scolded, he would feel distressed.

"Little girl, don't be afraid." The old man thought for a while, and comforted with a bit of seniority, "You lost in this fighting skill, your master won't blame you...."

Gu Bainiang laughed, this old man was thinking too much...

She nodded, this is certain, if she can't recognize these fake drugs, she won't blame herself, after all, she is still a beginner, and she can't get along with herself.

"Okay, you can look at my medicine first." The old man was a little impatient, and with a shake of his hand, he overturned the sack, and a large pile of medicinal herbs fell on the cart.

Gu Eighteen Niang looked at it attentively.

"Little girl, don't be unconvinced, you are also smart, so you were taught so well by the master, otherwise you can see my medicine at a glance? Hmph, but you can't be so arrogant, I'm not bragging, old man, if my master is still alive, I can't guarantee that I can tell what my medicine is at a glance......" The old man squinted, grabbed his knees with his hands, and muttered.

Before his words fell, he saw Gu Bainiang reach out and pick up the scattered medicinal herbs one by one.

"It's cowpea root..."

"It's a dead silkworm... Phew... Dead silkworms and lime ...."

"This is bayberry bark...."

"It's... Stone... Uncle....I think it's better for you to use alum to make Tianzhu yellow...."

With her words one after another, the old man was stunned.
