Go back to the past and be a schoolboy

After the simple greetings, Zai Tao didn't let Haber stay at sea too much. According to the original plan, he arranged for two guards at the port of a neutral country and sent him to the ship returning home.

Looking at the bustling port, Haber seemed like yesterday: "Mr. Zai, that child of mine..."

Zai Tao said politely: "Professor Haber, you can rest assured about this. We have sent other comrades over to deal with the child. If everything goes well, you will be able to meet him in mainland China soon."

Haber sighed, and said slowly: "That's fine, as the father became a deserter, I really don't want my child to stay here to suffer. If I can see my sister, please explain it a lot. Of course, It would be best if she is willing to follow her to China."

Zai Tao laughed and said: "Don't worry, we will definitely hand over the letter you wrote to them, but children can say, it's not certain what choice adults make, it's not easy to force them."

Haber struggled for a while, and finally took the suitcase, his voice could not hide his discouragement: "Forget it, she has her own life, as a brother, you can't continue to neglect your duties, let her go, but wait until China and make some achievements. Hopefully they will change my opinion a bit."

It's hard for an honest official to decide on housework, so Zai Tao didn't care so much when he got here. His task was to send Haber back smoothly. As for how to deal with it or arrange it later, that was Cheng Nuo's business.

I just hope that these foreign devils can continue to shine, and it is not in vain that they have traveled so far and traveled half of Europe to put on a big show in person.

Pulling out a red scarf from his bag, Zai Tao handed it over by himself: "This is the color that represents our China—red. I hope that next time we meet, Professor Haber can shine in the Academy of Sciences. Our dean is still waiting for your results. "

Holding the scarf, Haber was very moved: "Zai~you are my friend forever."

Zai Tao didn't think too much about it, and took a step back to tie it on the other party: "Whether you are friends or not, let's talk about it later. I just hope that you can escape the interception of the pursuers and reach the west coast of the Pacific Ocean safely."

Thinking of his current status as a "deserter", Haber looked quite nervous, and couldn't help stretching his neck to look around to see if he found his "chaser".

Zai Tao seemed much calmer, and quickly made the other party's movements smaller, and warned in a low voice: "Little Dianxin, if someone with a heart sees it, your identity, Professor Haber, will be exposed, and I don't need to say what the consequences are." ?”

Huber suddenly panicked: "I... I just looked up, there should be nothing wrong, right?"

Zai Tao patted the other party's shoulder: "Fortunately, it was only for a while, if it continues, even if it is not discovered, it will be noticed by others. When the time comes to really do something, the operating space will be much smaller. Now Listen to me, take a deep-breath-breath, yes, that's it."

After going back and forth for a few times, Haber finally relaxed a lot, and asked in a low voice: "Zai~Professor Cheng spent such a high price to rescue me, I can't do nothing, think about what I can do to help him .”

Although he was rescued right now, he also understood that if it was of no use to others, the possibility of being denounced again was unlikely, but being left out was a certainty.

It's okay for others, but Haber is different. He was the person in charge of a large-scale project before, so he is so lonely, life is hard to think about.

What's more, Cheng Nuo still has the "life-saving grace" for him, and Haber doesn't want to be looked down upon again.

Of course, there is another meaning, that is, through the news of the Paris meeting, he knows that China and Japan have very deep conflicts, and he has enmity with the Japanese. He is alone and weak, and has no chance of revenge. With Cheng Nuo's forces, the situation is quite different.

Thinking of this, Haber was full of energy again: "Zai~ Do you know what has the most things in this world?"

Zai Tao was a little confused, so: "What has the most things? It must be the most people, no matter where you go, there are people."

Haber shook his head and asked again: "Substance, I mean substance."

Zai Tao glanced at the sea not far away, hesitantly said: "Water?"

Haber's eyes lit up, and he hugged the other person's shoulders and said excitedly: "Yes, that is to say, there may be a lack of venues, talents, and even equipment for scientific research, but the most important thing is that there must be no lack of money. With money, everything is possible. not a problem……"

The more Zai Tao listened, the more confused he became. Before the other party finished speaking, he interrupted him directly: "Wait, wait, I understand the truth, but why did you get involved in the water?"

Haber looked left and right to make sure no one noticed them, and then carefully pressed it to the ear of the other party: "Zai~ Among these waters, seawater is the most. It has been proved by the data that these seawaters contain a full 8 million tons of gold. If We purify it by chemical means, then..."

"Then any funding is no longer a problem!" Zai Tao's breathing was a little short, and he followed the other party's words and said: "You can do any scientific research, so you don't have to be so tight!"

Haber looked confident: "Of course, with money, Satan can also serve you."

After a few words, Zai Tao's heart was also aroused. After Hubble was safely sent to the ship, he walked back and thought about the possibility of this matter. The various departments of the company don't have to cut down on food and clothing like this, and he will be one of the heroes when the protector comes back.

Going down like this, he can straighten his back in front of the dean.

Thinking all the way, I didn't even see the steps on the road, my feet were empty, and I almost fell to the ground.

Fortunately, his subordinates had sharp eyesight and quick hands. When they saw that the officer was wrong, they prepared in advance. When the other party showed signs of falling, he stepped forward and supported him: "My lord, what's wrong with you?"

"Me? What can I do? Of course it's a great thing." Zai Tao rubbed his subordinate's head habitually, and said with a smile: "By the way, send a telegram home to talk about the refining of gold from sea water, okay The news must be shared as soon as possible.”

Cheng Nuo was just about to rest in a courtyard in Beijing when he heard a commotion outside.

"Zhiyuan, Zhiyuan, are you asleep? Great news!"

"I haven't slept yet. What a great thing. Could it be that Mr. Tesla has made a breakthrough?"

"No, there is a greater good than that."

Putting on the clothes he had just taken off, Cheng Nuo walked to the door in cotton slippers, and it was Jiang Jiangzuo who opened the door and appeared in front of him.

At this moment, he was steaming, while shaking the telegram in his hand, his face was full of eagerness.

"Come in and tell me, it's cold outside, what a great thing it is that makes you so happy."

Get out of the way, Cheng Nuo let the other party in first, close the door and add a few pieces of new coal to the stove in the house, and the room became warmer immediately.

Ignoring the hot tea just poured for him, Jiang Jiangzuo said excitedly: "Didn't you arrange for Mr. Zai to meet Professor Haber some time ago, now not only do you have accurate information, but you can also help us solve a big problem. "

"Is that so? I'll take a look." Cheng Nuo took the telegram out of curiosity and wanted to see what was written on it.

Seeing the front, according to the arrangement between him and Zai Tao, after successfully receiving Haber, his face was full of smiles, but when he saw the great prospect of pulling some sea water to refine gold from behind, the smile on his face froze instantly.

Originally, Jiang Jiangzuo was very happy, but seeing Cheng Nuo's face suddenly changed, he began to feel a little uneasy: "To... Dean, is there anything wrong with the telegram?"

Cheng Nuo didn't answer the question directly, but asked instead: "You were so happy just now, is it all because of the matter of refining gold from sea water?"

Jiang Jiangzuo nodded fiercely: "Yes, you see that there are so many seawater in the world, and there are 8 million tons of gold hidden in it. As long as we grasp a small part of it, we can solve more than [-]% of the problems of our Academy of Sciences. It's..."

Jiang Jiangzuo spoke very vigorously in the front, but when he saw Cheng Nuo not only lost the smile on his face, but also became more and more gloomy, he suddenly felt that something was wrong, and his confidence in speaking became less and less, and at the end he whispered Said: "Dean, is there something wrong with this telegram?"

Cheng Nuo slapped the telegram on the table and pointed to the second half of the paragraph about gold: "Of course there are problems, and the problems are quite big!"

Although as early as 1872, scientists detected the composition of gold in seawater, and estimated that the gold content in seawater was quite high based on the situation at that time, and the total storage capacity was estimated to reach more than 20 billion tons.

After the end of the First World War, Germany was defeated and faced high war indemnity, so they decided to refine gold from seawater, and then began to develop and experiment with seawater, hoping to bring an extra income to Germany.

Numerous facts have proved that gold can indeed be extracted from seawater, but the extraction cost is much higher than the value of gold itself, and it is completely a loss-making business.

After the scientific experiment methods became more advanced in later generations, the gold content in seawater was further scientifically determined, and it was found that the gold content in different waters is also different.

For example, in the waters of the Atlantic Ocean and the northern Pacific Ocean, there is only one gram of gold in every billion tons of seawater, while in the waters of the Mediterranean Sea, the gold content is much higher, with one gram of gold in every ten tons of seawater.

But even so, it was far from the exaggeration of 8 million tons, and it was impossible for future generations to do it. Cheng Nuo didn't have the confidence to lead people to make breakthroughs directly a hundred years ago.

After hearing these things from the dean, Jiang Jiangzuo was a little dumbfounded: "So, Professor Haber's suggestion is a fantasy?"

Cheng Nuo sighed, and said, "The heart is kind, but with our means, the gains are far less than the sacrifices."

Jiang Jiangzuo was a little reconciled, and asked: "If we start to accumulate technology from now on, will there be such a glimmer of hope in the near future?"

Cheng Nuo shook his head, and said firmly: "The current extraction methods are nothing more than lime milk method and ion exchange resin method. If everything goes well, after working all day, the actual harvest is only ten or twenty grams, which is far worth If it’s not what we paid, the income and expenses can’t be evened out, so can we talk about anything else?”

Hearing this, Jiang Jiangzuo was completely discouraged, and his mood was very low.

Cheng Nuo couldn't bear it, folded the telegram and said, "Of course, all of this is based on the current chemical technology. If a certain technology is innovated in the future, maybe the seawater refining technology will be more mature and reliable. It’s just that right now, we still focus on more practical chemical pesticides.”

Turning the teacup in his hand, Jiang Jiangzuo looked complicated: "It seems that some things cannot be done overnight, and it is difficult to take a shortcut."

Cheng Nuo comforted him with a smile: "It's nothing. Compared with others, we have been taking shortcuts, and the speed is already much faster than others. What we have to do now is to bring these people back smoothly first, and do our best steadily. Don’t think about the things you can do for now.”

In the next few days, Cheng Nuo began to prepare for Haber, especially in terms of chemical plants, he could already start to prepare for the development of chemical pesticides.

The current domestic pesticides are still mainly inorganic compound pesticides. For example, the French discovered that mixing copper sulfate with lime water also has a control effect, and invented Bordeaux mixture inspired by this.

However, the specific application in agriculture is very effective. Cheng Nuo decided to usher in the era of organic chemical pesticides, especially DDT.

As an organochlorine insecticide, it can be processed into powder, emulsion or oil for use. It can not only prevent and control agricultural diseases and insect pests, increase agricultural output, but also control the incidence of domestic malaria and typhoid fever.

Even if it is because of the influence of the book "Silent Spring" and its side effects of environmental pollution, the WHO stated that it will be banned worldwide.

But only a few years later, many countries have re-used DDT. In addition to being used in agriculture, it can also help kill mosquitoes and control diseases such as malaria, dengue fever, and yellow fever. For the current domestic environment, Its positive side far outweighs its harmful side.

"It's best to make this thing before foreigners, and then apply for a patent as soon as possible. After all, a pesticide that is very effective against almost all insects, it is difficult not to attract the attention of the big powers once it comes out, and it is also easy to produce. If it is mass-produced, isn’t it better than some illusory refined gold?”

"Moreover, in the World War I that just ended, typhus broke out on the front lines of the European battlefield, causing millions of deaths. The main source of infection was the inability to kill lice and fleas. DDT was quite effective for these things, and there were frequent wars in the country. , can also use it."

"And this thing can greatly reduce the impact of pests and diseases. When there are high-quality seeds after selection and breeding, synthetic ammonia, and brand-new DDT, what reason is there not to double the grain output? If you can The production of agricultural machinery does not know how many lives of compatriots can be saved."

What kind of sea water refines gold, how can there be comfort from the land? (end of this chapter)
