Mountain Miscellaneous

Chapter 74

The press conference came to an end temporarily, and Li Changqing took a special car back to Zhong Nanshan.

The reporters still had many questions in their minds, and some stayed behind to explore the mysteries in the sound of the book.

The video of the media can only record the audio and video of Li Changqing reading, but there is no rendering of righteousness.

After the video was uploaded to the Internet, the response was mediocre.

Vibrate the clothes and dry the hillocks, and wash the feet for thousands of miles.

Li Changqing stood on the mountain shaking off the dust from his clothes, and washed the dirt off his feet beside the winding stream.

Promote the way of sages and sages outside the mountains, and cultivate your own heart in the mountains.

Li Changqing carried his hoe to the foot of Zhongnan Mountain to weed the grass, and the frog grass in the field grew purple seeds.

There is a hint of white on the edge of the purple seeds, and the middle is like a flower bud.

After Li Changqing cleared the weeds in the field, he poured spiritual water on frogweed, cabbage, cucumber, etc.

As the sun sets, the birds return to their nests.

Life in the mountains is peaceful and serene, and Li Changqing is still reading on the mountain.

The first ray of sunlight shines through the gaps in the wooden house, shining colorful colors.

Li Changqing set up the drawing board and used the brush in his hand to depict the beauty of the sunrise in the mountains.

However, Lijiaao Primary School was different from the past. Lijiaao was almost overwhelmed by cars of various brands!

In addition to the local residents of Guyang County, some media and people from nearby counties and cities were among the crowd.

Li Changqing led the reading as usual, but left the matter of selling leeks to Liu Cuie.

The media reporter wanted to interview Li Changqing, but when he was sober, he disappeared.

Li Shanyu deliberately refrained from listening to Li Changqing's reading, and waited at the foot of the hill early.

Li Changqing took the prepared Frog Grass and went straight to Jinzhu Pharmaceutical.

"Master Li, you really surprised me too much!"

"When we first met, you were selling peaches outside the fruit wholesale market for 30 yuan a catty!"

"After the supply of raw peaches fell short of demand, they insisted on not increasing the price."

"A few days ago, I learned that you are Li Jiaao's master of Chinese studies, and you are also a master of Xinglin!"

"In less than a few days, it broke out that you proved Goldbach's conjecture!"

Li Shanyu was driving the car and was amazed at the thought of Li Changqing's legend.

Li Changqing just smiled slightly and didn't say anything.

After arriving at the laboratory of Jinzhu Pharmaceutical, Gong Weiguo's assistants' eyes lit up when they saw Li Changqing.

"Miss Li, can you take a photo with me?"

"Ms. Li, can you sign the book for me?"

The young assistants surrounded Li Changqing excitedly with mobile phones, pens and paper, and said happily.

"Let's take a photo together!" Li Changqing said.

"It couldn't be better, it will be hung in the main hall of the laboratory in the future!"

Li Shanyu decided that Li Changqing was definitely not someone in the pool, so he nodded immediately.

Li Changqing stood in the middle, Li Shanyu and Gong Weiguo stood on both sides, and professional photographers took pictures.

"Professor Gong, have you done your preparations?"

After the episode, Li Changqing asked.

"Hehe, all you need is a live grass!"

Gong Weiguo is convinced by Li Changqing's proof of Goldbach's conjecture, but he is still not optimistic about using live grass as a solvent.

"The grass is on Mr. Li's car!" Li Changqing said.

"I'll get it!" Li Shanyu said.

"Just this grass, what's its scientific name?"

Gong Weiguo is an expert in the pharmaceutical field, but it was the first time he saw the grass in Li Shanyu's hands.

"Wonderful Frog Grass!" Li Changqing said authentically.

"Could it be a new species, where did it come from?"

Gong Weiguo searched in his brain, puzzled.

"A grass from Zhong Nanshan!" Li Changqing said.

"Is it the mountain where Master Li grows leeks?" Li Shanyu asked.

"En!" Li Changqing nodded.

"But how can a live grass be used as a solvent?" Gong Weiguo said.

"Get a pinhole straw!" Li Changqing said.

"Here!", one of Gong Weiguo's assistants handed the prepared pinhole straw to Li Changqing.

Li Changqing took the pinhole straw and inserted it into the purple seeds of the frog grass.

A transparent unknown liquid traced back into the straw along the pinhole.

"Okay!" Li Changqing handed the pinhole straw to Gong Weiguo.

"Ah, is this the end?" Gong Weiguo took the pinhole test tube given by Li Changqing.

"The rest are just routine work, you can do it!" Li Changqing said.

"How to do it specifically?" Gong Weiguo asked.

"What is the principle of solvent extraction?" Li Changqing said.

"The solubility of each solute in a solvent is different!" Gong Weiguo said.

"Dissolve the extract of the frogwort seeds in the test tube into the mixture of hydrogen urge mol and dehydro urge aldehyde."

"When it is diluted with distilled water, dehydrorushol can be separated from dehydrorushaldehyde!"

The frog grass that Li Changqing exchanged from "Shen Nong Baicao Jing" is a natural extractant.

"It's that simple?" Gong Weiguo asked suspiciously.

"It's that simple!" Li Changqing said lightly.

"Would it work, you'll know if you try it!" Li Shanyu said.

"I'll do it!" Gong Weiguo wanted to verify it himself.

The experiment process is very simple. Gong Weiguo dripped the extract of B. saliva seeds in the pinhole test tube into the beaker containing the mixture of dehydrorushol and dehydrorushaldehyde, and then poured distilled water!
The dehydrorushol and dehydrorushaldehyde in the beaker were immediately divided into upper and lower layers.

After Gong Weiguo passed the test, he stood there dumbfounded!

A living grass on Zhongnan Mountain!
The most common solvent extraction method in the pharmaceutical field!

Just solve the problem of separating dehydrorushol and dehydrorushaldehyde that has troubled me for more than half a year!

"Professor Gong, are you separated?" Li Shanyu asked with concern.

"Hmm!" Gong Weiguo said sadly.

"Thousands of employees of Jinzhu Pharmaceutical can finally continue to live a stable life, thanks to Master Li!"

Li Shanyu expressed his depression for half a year, and sincerely bowed to Li Changqing to thank him.

"It's just two rides!" Li Changqing said calmly.

"I'm ashamed, half a year's salary will be refunded to Mr. Li when I go back!"

Gong Weiguo was originally an expert invited by Li Shanyu to solve the separation problem of dehydrorushol and dehydrorushaldehyde, and he was deeply shocked and looked downcast.

"The separation of dehydrorushol and dehydrorushaldehyde is a difficult problem, and the delay of half a year cannot be blamed on Professor Gong!"

Li Shanyu knew that Gong Weiguo had done his best, and he had no intention of comparing Gong Weiguo with Li Changqing.

"In the past, Mr. Li said that Mr. Li was an expert in the mountains. To be honest, he didn't quite agree with it!"

"Until I realized that I was ridiculous just now, I apologize to Mr. Li!"

Gong Weiguo has always been suspicious of Li Changqing, but now he is completely convinced.

"It's normal to question, Professor Gong doesn't need to apologize to me!"

Li Changqing knew that his method was indeed different, and Gong Weiguo didn't say too much, avoiding it.

Gong Weiguo admires him even more for being young but not arrogant!

Something happened here, and when Li Changqing returned to Zhong Nanshan again, he found that the mountain was not very peaceful!

　Thank you for your rewards~
