At this time, the month-long training was completed, the warheads were returned to their positions, and the Chenhe fleet was again dispersed and entered the salt transportation business. The salt industry is one of the main sources of income for the Chenhe factory, and Yang Xi will naturally not let him break it.

Now that the Chenhe Chamber of Commerce is in full swing in Yuzhang and Jiangxia counties, no salt gang or family dares to use their brains wherever the Fanchenhe goes.

Yang Xi calculated, the Chenhe factory now has 14,000 employees, in addition to the more than 3,000 people in the combat team, there are 11,000 workers, this number is a super large enterprise even after more than a thousand years.

At this time, Jiangxia and Yuzhang counties alone could not afford to support such a large super enterprise, but Yang Xi's salt, paper, wine and other products were exported to various counties in Jingzhou and Yangzhou through various merchants.

Yang Xi walked while thinking, but he arrived at Chenhe School.

At this time, the total number of adults and children in the school every day is more than 3,000, and the area and buildings have also increased a lot compared to before.

In the distance, Yang Xi saw a nine-year-old boy sitting on the bench next to the school playground, it was Pang Tong.

Pang Tong was holding a drawing at this time, and he was drawing something with his fingers on it, Yang Xi walked in from behind to see, but it was the periodic table of elements depicted by Yang Xi.

Yang Xiguan looked at the sometimes puzzled and sometimes thoughtful, and it was not easy to disturb, for a few minutes, Pang Tong finally felt that there was someone behind him, and when he turned his head to see that it was Yang Xi, he quickly got up and saluted: "Student Pang Tong, I have seen the principal!" ”

Yang Xi nodded and said, "Yes, what do you think?" ”

"Back to the principal, I have gained a lot, the more I learn, the more I feel that the principal is knowledgeable and profound, but I am afraid that it is unprecedented."

"I don't want you to praise me, all the elements in the periodic table can really be separated from our Chenhe factory now, but there are only a few, and some others are only found compounds, and there is no technology to separate them at all."

Yang Xi thought for a while and said: "For example, now our salt mainly contains sodium chloride, but also contains chloride, such as potassium chloride, magnesium chloride, calcium sulfate, magnesium sulfate, sodium sulfate, potassium sulfate, magnesium carbonate and organic compounds.

There is also the mother liquor brought back by our fleet, which is also a mineral in seawater, which contains high concentrations of valuable minerals such as potassium, magnesium, bromine and sulfate. The phosphate rock that Camp Commander Cai retrieved in the mountains last time had phosphorus in it, which was the red phosphorus raw material I particularly needed, but no one tried to separate it. Speaking of this, Yang Xi looked at Pang Tong expectantly.

Pang Tong has been listening, and finally raised his head at this moment, and looked at Yang Xidao with a discerning gaze: "Tong has been following the principal for a long time, the more he finds that what he has learned is superficial, thanks to the fact that the principal does not treat each other as an outsider, and he has nothing to repay, and he is willing to share his worries for the principal, but his knowledge is limited, and he also asks the principal to point out a clear way, and he will definitely go all out." ”

Hearing this, Yang Xi finally relieved his heart, this Pang Tong was finally about to be regarded as his own person.

"Don't rush to the task just yet, let me ask you, what are your ambitions?"

Pang Tong looked at the sky, and then looked at Yang Xidao: "Tong had ambitions when he was a child, wanting to protect his family and defend the country, and be a famous minister to leave a green history." ”

When Yang Xi heard this, he was unsure, but he heard Pang Tong say again: "But since I studied with the principal, I feel more and more that no matter how good I am in learning, I can save a few people in troubled times, and be a famous minister, no matter how good I am, I can satisfy a few people."

Look at the headmaster, who is called a strange and ingenious thing by outsiders, just one of them, you can live a few people.

If the curling plough and threshing machine made by the principal can be promoted all over the world, it can save half of my manpower. The keel waterwheel can turn many dry fields into paddy fields.

The bamboo paper made by the principal can make many people from ignorant villains to people of insight. There is also a strange book of the Compendium of Materia Medica made by the principal, if the world's doctors practice it, I don't know how many more people can live, and how much separation of flesh and blood can be avoided.

All of this, one by one in the heart of the unity, the unity now only wants to learn more miracle skills from the principal, and by extension, this is the ambition of the unity at this time. ”

Yang Xi listened to Pang Tong's narration at this time, and couldn't help but be a little stunned, unconsciously, he had done so much, and each of these items could push the wheel of history one step forward.

Pang Tong looked at Yang Xi silently, and just stood on the opposite side silently, with a respectful look on his face, Yang Xi at this time, in his young heart, had become extremely tall.

is indeed tall, they are all eight feet tall, a few centimeters short of one meter nine, and Pang Tong is only about one meter three or four.

After a long time, Yang Xi came back to his senses, looked at this Pang Tong cautiously, and said: "You have been studying for almost three years, and you have also achieved a small success, the principal has appointed you a task today, and I hope you will face the difficulties." ”

"But please ask the principal to command, the students will spare no effort!"

"Good! From today onwards, Chenhe School has established a chemical research institute, you are temporarily the acting director, all the existing resources, apply directly to me, I will fully cooperate with you, if there are any problems that can not be solved, you can also consult me. As for the members, the entire Chenhe factory, whoever you like, you can ask me, within a month, if the extraction of red phosphorus and white phosphorus is completed, your agent will be removed. ”

Yang Xi has long thought about the establishment of a chemistry laboratory, but the previous foundation is not enough, and now it has been almost five years, with a solid foundation, and there are some talents who are interested in chemistry, and it is time to slowly embark on this path.

Yang Xi wants Pang to take the lead, extracting red phosphorus and white phosphorus, it is not hot-headed, there is no problem with this raw material, and there are methods, only some specific equipment experiments are missing, if it is successfully extracted, plus sulfur and binder, you can directly make matches.

With matches, this is a different world.

Every household does not need to leave fire, and this habit of life that is easy to cause fire is too speechless. When people go out, they don't have to carry iron bars and wooden tunnels to engage in friction and fire for half a day.

At that time, the unique technology of matches, I don't know how much benefit it will bring to the Chenhe factory, and how much change it will bring to people's lives.

Now Yang Xi can completely make black powder, but this kind of killing weapon cannot be made casually, in case it is introduced into the hands of some warlords, then the Three Kingdoms will really become a powder keg at that time, and I don't know how many people will die because of it.

This kind of killing weapon will only appear when Yang Xi thinks it should appear.

Yang Xi returned to the Chenhe factory, stayed in the office for more than four years, and began to think about the next move.

"It's time to get started!"

"In the age of great industry, how can there be no steel!"

"Now the preparations are almost complete, with people, technology, and money, and only one last step is to find the iron ore."

"Caishi Mountain, should be an iron mine, from the geographical analysis, Caishi Mountain is located in Daye, Hubei, although after more than a thousand years of changes, the landform has changed greatly, mountains and rivers are likely to disappear, but iron ore will not disappear and suddenly appear, more than a thousand years later, then there must be now."

Yang Xi decided to investigate in person, after all, this is a very important step, and there is no room for small problems.
