Monitoring oxygen changes in the air sounds easy, but it's actually very difficult. Although there is a small experiment in junior high school chemistry that can determine the amount of oxygen in the air, it is done in a small container. If it is placed in a large area, this needs to be averaged by weather aircraft.

However, the problem is that the Kunlun Mountains are divided into three sections in the north, the middle and the south, and only the southern, east, west, and central sections, which occupy a quarter of China's country, and it is a big problem to monitor the changes in oxygen content in a certain area within these ranges.

Asimov gave Li Shaoyang the method, but how to implement it is his own business.

At this time, after receiving the task from above, the China Meteorological Administration organized 12 top meteorological experts to gather together to discuss this issue.

Wang Shan presided over the meeting, asking everyone to speak boldly, without considering cost and technical issues, and to find a feasible and efficient method.

"It's hard." An expert frowned: "Even if there is a large amount of oxygen produced nearby, it will soon be diluted into the air, unless it is a super large amount of oxygen that is enough to change the climate near the Kunlun Mountains, but that is impossible, not to mention one person, it is a country, no, the countries of the world together cannot produce so much oxygen." ”

"Hey, if that much oxygen is released, the earth is going to be finished." Another expert quipped: "The composition of the air we humans breathe is perfect, with nitrogen accounting for 78%, oxygen 21%, and the rest of noble gases such as carbon dioxide." If the oxygen content is too high, it will cause oxidation of the body's organs and even kill the cells. ”

Wang Shan frowned: "Make it clear." ”

The expert got up and picked up an apple on his plate, cut it with a knife and set it aside: "In a few minutes, the flesh of this tender apple will turn brown, that is, it will be oxidized, and a few percent higher oxygen content in the air will cause a large area of biological death, which is not a trivial matter." ”

"It can also cause wildfires and even change the structure of the atmosphere!" Other experts talked about it.

"Note that we're talking about monitoring changes in oxygen in a certain area, not about the dangers of oxygen to the atmosphere." Li Shaoyang, who was sitting in the innermost, got up and said.

Wang Shan hurriedly coughed: "I heard it, don't say something useless." ”

Many experts looked at him in surprise, what is the identity of this young man? Why did even the king's chief listen to him?

The experts continued to discuss, but until the afternoon, no results came out.

Just when Li Shaoyang and Wang Shan were losing patience, a young man stood up: "I have a way, but I don't want to say it now." ”

Suddenly, everyone's eyes were on him.

This young man was about twenty years old, but he had a mustache and a dissolute look, and even the buttons of his suit were wrongly buttoned, which was very odd.

Wang Shan dissolved the meeting and told him to go to the hut next to him, but the young man did not say a word.

In desperation, Wang Shan found his leader, an old professor of the Chinese Academy of Sciences, who was also the young man's mentor.

The old professor sighed to Li Shaoyang and Wang Shan: "This is my student, his name is Cui Zijian, he came out of the junior class of HKUST, he went to college at the age of twelve, but he was born introverted and was diagnosed with autism. This time, he was asked to participate, mainly because of his research in the 'practical sciences'. ”

Li Shaoyang interrupted him: "What is practical science? ”

The old professor smiled: "It is to obtain scientific results in an experimental way without considering theories and formulas, which is a research method that is opposed in the international scientific community." Because we still pay attention to the establishment of theories, we can confirm the accuracy of experimental results. ”

The old professor introduced this very alternative research method: "In fact, the simple scientific concept of our ancient China is to pay attention to practice and practicality, so the ancient scientific and technological civilization of China is mainly based on various inventions and practical use of technology, while Western science and technology starts from theory, so in modern times, our science and technology lag far behind them." ”

This statement is described in detail in the famous Professor Joseph Needham's book "The History of Ancient Science and Technology in China". But the old professor was talking about Cui Zijian, a student.

"He is very intelligent and can often come up with some whimsical experimental methods, but this student, in recent years, has begun to go down the evil path, specializing in some pseudo-sciences, such as qigong, Taoist cultivation, and so on." The old professor sighed again: "It's a pity that the good seedlings, Cui's classmates have dabbled in biochemistry, physics and astronomy, and he is an all-rounder." ”

Li Shaoyang's heart moved: "Do you know why he didn't say what he thought?" ”

The old professor looked at Cui Zijian, who was sitting in the hut without saying a word, and lowered his voice and said, "I think Classmate Cui thinks it's not interesting to say it, because no one will believe him." Recently, he has been working on something called Yuanqi, saying that it is a special energy of the universe, similar to the Zhenqi in Xiuzhen's novels, and I have criticized him for this. ”

Li Shaoyang's heart jumped again, so he asked Wang Shan to send the old professor away.

He thought about it at the door, and called Jiu'er.

When the pretty Jiu'er appeared in front of Cui Zijian, he was obviously uncomfortable, but Jiu'er pulled him up, stuffed him directly into the car after going out, and went straight to the Flower Pavilion.

Cui Zijian became angry in the car: "You guys are kidnapping." ”

Li Shaoyang, who was driving, snorted: "I just hope you really have some ability, but this is not a kidnapping, but hiring!" ”

Cui Zijian was stunned: "What to hire?" ”

Jiu'er snorted: "Our boss wants to hire you as a consultant, do you know the Northern Group?" ”

Cui Zijian sneered: "I'm not interested, I won't go as much as you want." ”

Li Shaoyang took out a blue fire pill from his pocket and gently threw it to him: "What about this thing?" ”

Cui Zijian began to touch the elixir disdainfully: "What kind of toy is this?" ”

But then, a strange scream suddenly came from his pocket. Cui Zijian's face changed greatly, and he quickly took out an electronic watch-like thing from the pocket of his underwear, and gently approached Bihuo Dan, and the smart watch made a sound: "Monitor the vitality, the value is 009, and the change curve function is determined to be 0-1-1......"

Cui Zijian shouted desperately, took out his mobile phone in the car, opened a program, and calculated quickly.

"This is a very stable Yuan Qi value, which means that there is a stable Yuan Qi essence in this pill, and according to the curve chart, it will change over time." Cui Zijian entered a few values on his phone. Handedly handed the watch to Jiu'er: "You, take it, report the data to me every five minutes." ”

Jiu'er pouted, did she think of herself as an assistant!

Li Shaoyang, who was in front, said in a deep voice: "Listen to him!" ”

Jiu'er reluctantly picked up the watch.

From the Academy of Sciences to the Flower Pavilion, because of the traffic jam, it took an hour, and Jiu'er reported the data twelve times halfway, Cui Zijian excitedly listed the data: "Look, although the change is very small, the curve chart is not a straight line, which shows that the pill changes with time, and the more it is noon, the more vitality it has." ”

Li Shaoyang stopped at this time, opened the car door, and said with a smile: "You just detected the yang force, and at about 12 o'clock in the evening, the yin qi of this pill is the strongest, and your function is only positive, and no negative curve is added." ”

Cui Zijian looked at him in shock: "You are right, I forgot the truth of the change of yin and yang." ”

He sat in the car and couldn't get down, but shouted: "Prepare a computer for me, ask for the best, give me this elixir, let me study it for half a month, and I will tell you the experimental method for detecting oxygen." ”

Li Shaoyang smiled, asked Jiu'er to get out of the car first, and then took out a more advanced Tai Chi Dan, shook it in front of him, and silently pulled Jiu'er into the house.

Cui Zijian, who was behind, naturally desperately got out of the car, and followed him like a puppy and kept shouting: "Give me, show me the medicine just now, feed the big brother, you can show me." ”

Li Shaoyang walked into the inner room of the Flower Pavilion with a smile, and asked Jiu'er and Isabella to be on guard, but pulled Cui Zijian to the entrance of the basement: "Let's go in, let's have a good chat." ”

Cui Zijian followed him down the dark basement in a daze, and then he panicked: "Hey, what are you going to do, is this to lock me up?" ”

But then he saw that spectacular circle of Taoist scriptures, and he couldn't help but be stunned.

"These are Daozang?" Cui Zijian looked at the title of the book, and suddenly opened his mouth wide: "It's so complete, I spent so much money, and I only found less than 500 volumes, you have to have tens of thousands of volumes here." ”

"Just look at it." Li Shaoyang smiled, took out the Aoki Ding, and then released the materials he took from Wang Yaoji.

Cui Zijian almost fainted when he saw this scene: "Oh my God, there is really such a thing as alchemy!" ”

And when Li Shaoyang sat down cross-legged and began to absorb the Dan Qi of Dingzhong, Cui Zijian knelt down directly, prostrate on the ground and shouted: "Immortal...... Please be worshiped by me, a mortal. ”

Li Shaoyang pulled him up with a smile: "Come on, I'm not an immortal, just an ordinary person." ”

Cui Zijian didn't believe it: "Just now my watch detected a value of more than 100 vitality, which is already a legendary miracle." ”

Li Shaoyang asked him to sit down: "Tell me, what does this vitality value represent?" ”

Cui Zijian scratched his head: "To put it simply, there is vitality everywhere in this world, but the value is very, very small, and the one I detected the most is on the side of the Northern Garrison, and the average value over there is about 0.1." In other places, such as Kyoto's Vientiane Mountain, the value is 0.03, as for the urban area, the Chang'an Bridge is very weird, about 0.8, and other busy roads, not even 0.01. ”

Cui Zijian turned on his mobile phone and asked Li Shaoyang to look at the national vitality map he had drawn.

Because of his autism, he rarely travels, so he hasn't been to many places, some tourist destinations with groups, and suburbs near Kyoto.

"From these data, I can infer that the average vitality content of the whole country is about 0.02. And your medicine has reached the value of 7 yuanqi, and the vitality that came out of your green wood pot just now is already a value of 99.8, which is equivalent to 5,000 times the national average. ”

Li Shaoyang looked at him silently, and said for a long time: "Your math is good." ”

Cui Zijian was going crazy: "Don't insult my IQ, if the vitality content is about 1, you can cultivate, this is what I secretly went to Wudang Mountain to do experiments." If you reach a value of 5 or more, you will be able to absorb it directly by the human body. Do you understand, this is the mystery of cultivation, the mystery of vitality! ”
