When Fu Xi was training people, Lu Xiaoman was like a fish in water on Uncle Chen's side.

The disciples of the intermediate class looked like young people, all of them had delicate and smooth skin, and they couldn't tell their real age at all by looking at their faces, only Lu Xiaoman was an undeveloped child, and Uncle Chen specially adjusted the seat for her and let her sit in the first row.

Lu Xiaoman's name has spread among the outer disciples in the past few days, his memory is outstanding, his arithmetic ability is outstanding, and he is born to study the formation to enter the Dao seedlings, Jin Dan Zhenren personally taught from the elementary class, and when Uncle Chen said her name, there were all voices of sudden enlightenment.

After arranging Lu Xiaoman, Uncle Chen sent a small storage bag, which contained all kinds of elixirs to learn to identify today, and the main content of the intermediate course was to identify medicinal materials, especially for medicinal materials with similar appearance, smell and medicinal properties.

These elixirs are the real objects on the elixir set in the primary class, Lu Xiaoman learned from others, carefully took out the medicinal materials one by one and spread them neatly on the table, but others took the elixir set flip book to find the answer corresponding to the real thing, Lu Xiaoman didn't dig out the book, she picked up the medicinal materials one by one after putting them in place, and looked at the leaves with leaves, flowers with flowers, and roots with roots, and her comparison and verification were all carried out in her mind.

Uncle Chen's class habit is to give the disciples time to turn the book for self-study after handing out the medicinal materials, and then she asks some questions to answer, and everyone's performance in class is clear at a glance.

Lu Xiaoman saved the time of flipping through the book, she quickly finished studying her medicinal materials, and looked left and right to see that everyone else was still busy, she lowered her head and looked at her notes, she hadn't written the homework assigned by Kunyu Zhenren yesterday.

Uncle Chen knew what Lu Xiaoman was doing with a sweep of his senses, but he was helpless, his eyes were closed, and he meditated by himself.

Half an hour later, most of the people had put down their books, and Uncle Chen asked everyone to put them all in the corner of the table, put their hands under the table, and then ask questions at will.

At first, it was easy to ask a few questions, and the disciples who were named answered smoothly, and after five or six people, Uncle Chen called Lu Xiaoman's name.

"Pick out the beauty palm and water ghost grass in your hand, and tell me what is the difference between them?"

As soon as Uncle Chen finished speaking, the disciples below gasped.

"The appearance of the beauty palm and the water ghost grass are exactly the same, the number of flower buds, flowers and even stamens are the same, the only difference is the leaves, the leaf edge of the beauty palm is fine hair, the edge of the water ghost grass leaf is sharp thorns, slightly toxic, scratching the skin is not itchy or painful. In the commonly used pill formula, the beauty palm is the main ingredient of the trauma medicine, and the water ghost grass is the main ingredient of the poison avoidance pill, if you make a mistake, the alchemy will not blow up the oven, but the trauma medicine mixed with the water ghost grass will have symptoms of skin swelling and pain after being rubbed on the wound. In addition, the water ghost grass is a common medicine for immortals, and mortals also often use this medicinal material to pull out poison. Lu Xiaoman accurately picked up the Water Ghost Grass and Beauty Palm from the table, although they were already concocted medicinal materials, there was still no difference in appearance.

"Impossible!"

"Nonsense!"

"How can the water ghost grass be a common medicine for immortals? I've never heard of it, but there are still things shared by immortals in this world? ”

Everyone shouted at Lu Xiaoman's answer again, and Uncle Chen also frowned slightly in disapproval.
