Of course, what is easy to understand for Guo Zhiyuan, a time traveler, is a miracle in Zeng Qisheng's opinion! When he followed Guo Zhiyuan to the constant temperature hatching house in the hatchery and saw furry and cute ducklings, and the goose broke out from the shell without hatching the hens, his eyes suddenly widened again, and he said in amazement: "This is also your invention, sir, right? It's so amazing! In this way, ordinary people can live a life of eating meat, which is another great good policy!"

Guo Zhiyuan had long guessed that Zeng Qisheng would react like this, and smiled and said, "Actually, it's nothing. It's nothing more than simulating the environment where hens hatch chickens, so that the young poultry can break out of their shells, so that the reproduction speed of poultry can greatly improve the poultry reproduction speed. In addition to eating poultry meat, the poultry eggs produced every day are also very considerable. This time, immigrants from the mainland are very thin, and farming and building cities are all heavy physical labor. I'm afraid they can't bear it, so I can only raise more poultry to help them replenish some meat..."

Zeng Qisheng sighed: "Our adults love the people as much as their sons, which is a blessing for my immigration from the East!..."

Guo Zhiyuan smiled and said nothing. He waved to the person in charge of the hatch planted farm and asked about the specific situation of the hatching of eggs. He learned that the hatching rate of eggs is about 50%, Guo Zhiyuan couldn't help but sigh and said, "What a pity, if the thermometer can be used, the hatching rate should be greatly improved!"

Zeng Qisheng, who was standing by, exclaimed: "It only takes two breeding eggs in three to seven days to hatch a young poultry. This is incredible. If a hen hatched naturally, it will take at least half a month! By the way, sir, what is a thermometer?..."

Seeing that Zeng Qisheng was almost becoming a "curious baby", Guo Zhiyuan was secretly amused and did not give much explanation to Zeng Qisheng. Anyway, the workshop has found a way to burn glass, and it should not take long to make the thermometer. At that time, the knowledge of thermometers can be popularized in the study class of Dongfan Academy.

After leaving the hatchery, Guo Zhiyuan took Zeng Qisheng to see the salt drying field. The salt fields along the coastline were endless. It was so spectacular. However, Zeng Qisheng had a wide range of knowledge and had heard of the salt drying method. He was not too surprised. He exclaimed: "Is this the salt drying method in Haifeng, Shandong? It's really magnificent to use the heaven and earth as the furnace and the beach as the field road! It saves manpower and fuel, and it's really economical. Unfortunately, the sea salt obtained from the salt drying method is too much impurity, which is not as fine as well salt and lake salt..."

Guo Zhiyuan looked at Zeng Qisheng. It seemed that Zeng Qisheng was indeed different from those sour scholars who turned a blind eye to the outside world and only read the books of sages. They were quite knowledgeable. People in this era mainly judged the quality of salt by the whiteness and fineness of salt. The whiter and finer the better. Therefore, the nobles and nobles do not eat sea salt. They all like the well salt in Sichuan and the lake salt in Qinghai. Even the mouthwash is used as the standard for a luxurious life. Only poor people will buy coarse and black sea salt.

The Haifeng in Shandong mentioned by Zeng Qisheng is actually talking about Wudi County in Shandong Province. This place is an important sea salt production area in China. The locals have lived by salt workers for generations. In the Ming Dynasty, in order to avoid the taboo of Zhu Di, the Emperor Chengzu of Ming Dynasty, it was changed to Haifeng. The salt-drying method had already appeared in Haifeng, but it was officially recorded in the book until the end of the Ming Dynasty. The famous scientist Song Yingxing mentioned the salt-drying method in his "Tiangong Kaiwu", but it still did not attract the attention of the rulers. Zeng Qisheng was able to know the salt-drying method, which shows that his knowledge had exceeded most people in this era.

Of course, Guo Zhiyuan's salt drying method is actually very different from Shandong Haifeng's salt drying method. Shandong Haifeng's salt drying method simply uses the physical effects of sunlight and sea breeze evaporation, so only coarse salt can be obtained. However, Guo Zhiyuan's salt drying method borrows modern purification technology and adds additives such as barium chloride, sodium hydroxide, sodium carbonate, dilute hydrochloric acid solution to the brine for further purification. This is chemical action, and naturally it is not something that people of this era can understand.

This is also a high-end secret of Dongfan. Guo Zhiyuan has no intention of making it public, so Guo Zhiyuan requires strict confidentiality. The salt workers involved in the final purification process have been carefully selected and surrounded the final purification salt fields with fences. A large number of soldiers were sent outside to guard the secrets to prevent the secrets from leaking.

So when Guo Zhiyuan took Zeng Qisheng into the fence, Zeng Qisheng saw the snow-white salt mountains behind the fence, and immediately exclaimed: "This... this is fine salt, the best fine salt! I have never seen such white and fine salt! Big... How did you do it?!..."

Guo Zhiyuan has become accustomed to Zeng Qisheng's "fuss" and pointed to the snow-white salt mountain and introduced: "The salt drying method used in Dongfan is less than half of the traditional salt cooking method, but the output is more than twice the amount. The salt quality obtained is also better than the salt boiling method. At present, the annual refined salt production in the salt fields can reach 500,000 stones, and the scale of the salt fields will double next year, and the annual refined salt production can be one million stones..."

Zeng Qisheng finally came back from his shock, and held a handful of salt in his trembling hand. He watched the snow-white and crystal grains of salt leaking like fine sand from the gaps in his fingers, and exclaimed: "Qi Sheng realized today that he was a frog at the bottom of a well. If you have this technique of turning stones into gold, why worry about the rise of the East!..."

This time, following Guo Zhiyuan to inspect Dongfan, Zeng Qisheng opened his eyes and strengthened his loyalty to Guo Zhiyuan. Like Zeng Qisheng, the talents selected from the first batch of inland immigrants were also shocked by the various novel things they saw in Dongfan, and were even infected by the prosperous atmosphere here. They quickly integrated into a new environment, displayed their talents in their respective positions, and pushed the construction of Dongfan to a new height!

With the addition of these talents, the construction of Dongfan has become more orderly and has truly entered the track of rapid development. Guo Zhiyuan was able to free himself from the heavy and specific affairs, boldly delegate power, and hand over the specific affairs to Zeng Qisheng and others, because there is still a very difficult problem waiting for him to deal with, that is, how to get along with the natives of Dongfan.

Although Guo Zhiyuan occupied Dongfan, he was only considered an outsider after all. The natives who had lived in Dongfan for hundreds of years were the real masters of Dongfan. It can be imagined that these natives in Dongfan would definitely not welcome Guo Zhiyuan and others, and could even be said to have strong hostility. If the relationship with these natives in Dongfan is not handled well, then Dongfan will be far from being stable. Once a conflict breaks out, it is likely to bring variables to the current good development situation of Dongfan!
