Two soft sounds, the sound of the knuckle knocking on the stone wall with small force.

Lu Qiming turned around when he heard this, and was stunned to see an old man in a brown robe crawling up panting, raising his hand with a serious face—he was still in the posture of knocking on the door just now.

The old man was thin, his beard and hair were white, but his eyes were bright and bright, and he looked very energetic. He only snapped it twice, and it was clear that he had no malice.

Lu Qiming saw that the old man's outfit was clearly a doctor, so he couldn't pretend not to see it. He immediately got up and withdrew the isolation formation, but before Lu Qiming could say hello, the old man actually made a big blow to him first, and the crown almost didn't hit Lu Qiming's nose.

Lu Qiming was taken aback, immediately avoided the side, and hurriedly said, "Teacher, what are you doing?!"

Zhao Gongming looked at him fixedly, and said with a glance: "After reading the article you wrote, the old man scolded you in the medicine hall first, and was ready to deduct you thirty points." ”

Lu Qiming choked suddenly, and waited for him silently.

I only heard Zhao Gongming continue: "After that, the dean came over and said that you were not wrong - then naturally I was wrong." So I made a special trip to apologize to you. ”

Lu Qiming couldn't cry or laugh, so he could only say: "You don't have to be like this, I don't know about it." As he spoke, he leaned sideways and made a gesture to invite in.

Lu Qiming was originally a subconscious etiquette, but Zhao Gongming nodded very seriously and walked in, sat cross-legged on the spot, and said at the same time: "Of course it is necessary." You don't know, but there's no one but you. ”

Hearing this, Lu Qiming smiled slightly, and also sat down on the ground opposite him.

Zhao Gongming said directly: "I trust the dean's judgment, but I still don't know where you are." ”

Lu Qiming already has some understanding of his character, and he doesn't talk nonsense: "Then let's start with the four reverse soups?"

"Very good. Zhao Gongming showed a hint of a smile, and said seriously: "The four reverse soup and three yin are universal, and they are the prescription for strengthening the fire in Wenli." How can the sweet fruit play a leading role in it? In my opinion, the sweet fruit should be the 'assistant'. But how do you think that Ganguo should be used as a 'king's medicine'?"

Lu Qiming said without thinking: "Sweet fruit warms and nourishes yang qi first, and then it is the role of ginger and yang to win cold." ”

Zhao Gongming shook his head and retorted: "Sweet fruit 'tastes sweet', this kind of herb has a slow onset of action, and it is not suitable for emergencies. For example, when the yin is weak and cold, it is necessary to warm it as soon as possible - this stage has a quick effect, and the four reverse soup can be prevented here. No matter how you look at it, the ginger of 'Xinwen' is the king. ”

Lu Qiming smiled and said first: "There is really no doubt that the Four Reverse Soup is used as a medicine to warm the yang, strengthen the fire, chase away the cold, and save the adversity; After a pause, he asked rhetorically, "But may I ask the teacher - where is the use of the Four Reverse Soup?"

Zhao Gongming froze for a moment, nodded slowly, and said, "It's more of a Shaoyin and a Shaoyin." ”

"That's right, at these two stages, it's not just the upper middle and second Jiao that are deficient, but the lower yuan is also at a loss. Lu Qiming recalled the time when he studied under the elder of the Jiang family, and said: "According to your words, it is 'the water cold does not hide the dragon', and it is easy to turn into 'dragon fire leap'. ”

Hearing the last four words, Zhao Gongming's face was a little solemn, and he muttered: "People with weak yang qi and cold inner strength should have used warm medicine and gunpowder at this time, but ......"

Lu Qiming nodded: "It's the mercury of the potion instead of the real mercury, and it will fly when it encounters fire." ”

Zhao Gongming was stunned and a little dazed.

"Xiao Zhao, don't care about it, this kid is scaring people with Dan Dao's words!" Zhang Dayan suddenly came out, his expression was very disdainful, and he said bitterly to Lu Qiming: "At a young age, what do you do to learn alchemy? Our traditional medicine refining is a really good thing!"

Lu Qiming smiled bitterly. Since alchemy spread in this world, many people regard it as a treasure, and a considerable number of people think that Dan Dao is too demanding, and it is naturally not beautiful to go against heaven and earth. As a result, within the doctors, there was an endless debate over whether the pill was better or the medicine, and it was clear that Dean Zhang belonged to the latter.

Zhang Dayan had already tacitly acquiesced to him as his apprentice without Lu Qiming's knowledge, so he was not polite to him, and said, "Keep going - say that people can understand!"

Lu Qiming sighed and said quickly: "Ganguo is used here as a 'soil store' - to make the fire cooked without scorching, and warm and not scorched. ”

"It is also based on the previous saying of 'dragon fire leap' - only sweet fruit can make dragon fire turn back, so that ginger attaches to the warm and nourishing effect of Xinwen to Hexi. ”

"Therefore, the four reverse soup returns to the yang to save the adversity, and the sweet fruit is the key. ”

Zhao Gongming listened, stopped talking, and only glanced at Zhang Dayan.

Zhang Dayan bowed his head slightly, and explained more: "This was written early, and that person is not a professional doctor, so he is really not rigorous enough for these down-to-earth explanations." But the quarrel between the kings and ministers of this sweet fruit has been long enough, and it is the first time I have heard it as sure as this kid said. But—"

He glanced at Lu Qiming's expression and was unmoved, so he couldn't help pouting, so he had to answer angrily: "...... But there is some truth to that. ”

Lu Qiming smiled but did not speak.

Seeing that Zhao Gongming was silent, Zhang Dayan floated over and put his arm on his shoulder and said, "Xiao Zhao, how can you be persuaded so easily this time?"

Zhao Gongming said: "I originally had some doubts about this before, but after listening to Lu Xiaoyou, I straightened it out a lot. ”

"But?" Zhang Dayan reminded.

Zhao Gongming suddenly slapped his thigh and said, "But the new eleventh use of the 'Empty Source Wood' you wrote - the seventh of them!" He took a deep breath and said resolutely like a mountain and river: "Absolutely not right!"

Lu Qiming frowned, and said with determination: "How it is, I have written clearly enough." ”

Zhao Gongming leaned forward and said at a faster pace: "I remember, but what you said was that you added the Qingling Spring when you first refined the Nine Points—but you made a clerical error?"

"Of course not. Lu Qiming's head was big, and he said slowly: "The outer periphery of the Empty Source Wood is full of vitality, even if it is a spring at the time of the nine-point fire, as long as the timing is right-"

"Impossible!" Zhao Gongming waved his hand categorically, raised his voice and said, "You haven't tried it for me?!"

"Who told you not to go to Mu Xin?" Lu Qiming heard this, and immediately interrupted: "You must go to Mu Xin first! I wrote clearly, the empty source wood section, the place where the next three and seven are facing the sun - that location is the meeting point. Any alchemist can control it with mental power!"

Zhao Gongming shook his head and said: "You can't look at it like this, convergence is convergence, but everything in the world is a complete whole, and the idea you said obviously cannot be realized." ”

Lu Qiming took a deep breath, "Have you tried my method?"

Zhao Gongming said as a matter of course: "The old man has been refining medicine for decades, how can he still try it? Just think about it, you will know that it will not work! It will definitely not work!"

This old man is really stubborn! Lu Qiming was furious: "Bring the medicine ding! I'll let you see it now!"
