"As for bearing issues, you can build your own bearing factory. As long as you learn how to produce bearings, you will definitely make a lot of money by building a bearing factory in Shanghai. But you can only produce it yourself and cannot expose the methods of producing bearings." Fang Yizhi smiled while touching his beard.

Qi Lisun said: "Of course we won't reveal it. If we learn how to make bearings, we will find a treasure."

After the Shanghai Car Manufacturing Factory sent someone to Guangdong to discuss learning the bearing production process.

The person sent by Qi Lisun arrived in Foshan and went to the steel factory. He just mentioned that he wanted to learn the bearing production process, but was immediately rejected by Foshan: "Our technology will never be passed on, and bearings are not our patents. We can pass it on to you unless we have permission from the Duke of Chu."

"Just this matter, do you need the Duke of Chu to allow it?" The old craftsman who was sent was stunned and widened his eyes.

"Of course, don't underestimate this bearing. This thing is a powerful weapon for the country! Why are our Ming Dynasty cannons so light, and the twelve-pound heavy cannons can run as fast as cavalry by pulling them by horses. The mystery lies in the bearing."

The old craftsman was named Zhang Liang. After being rejected, he didn't want to go back in shame, so he sent a letter back to the Shanghai Car Manufacturing Factory.

Since Li Guodong returned to Nanjing, under the stimulation of the policy of Chu Duke's encouragement for business, the express delivery industry in the Ming Dynasty has developed rapidly. Private express delivery companies have sprung up like mushrooms after a rain, such as Songtong Express in Shanghai, Suzhou's Sushun Express, Jiangning Express in Nanjing, Yangzhou's Yangshun Express, Yuetong Express in Guangdong and other express delivery companies.

Those express companies adapt to local conditions, have their own fast transportation, and have their own fast ships and fast horses. The fast ships use new small three-masted schooners. The maximum speed can reach more than ten knots when sailing on the sea surface. It only takes about five days to arrive from Guangzhou to Shanghai. With the express delivery classification and transshipment time, it only takes six days to send a letter from Guangzhou to Shanghai. There are also fast horses to deliver letters on land. The express company has purchased Mongolian horses with good endurance but not very strong load-bearing ability. In places where there is no ship to arrive, the express delivery person rides a horse to deliver letters.

With the development of the express delivery industry, the communications industry has become much more convenient. Couriers from different companies wore different colors of clothing and rode fast horses back and forth between cities. The express delivery industry even spread to the territory of the Qing Dynasty, allowing some relatives and friends to communicate with each other through letters between the Qing Dynasty and the Ming Dynasty.

At the same time, the express delivery industry also prayed for the promotion of the development of the newspaper industry. With the express delivery industry, various news can be spread throughout the Ming Dynasty as quickly as possible, and newspapers issued by newspapers can also be delivered to all parts of the country as quickly as possible.

In addition to various express delivery companies, Li Guodong also established a mail company called the Ming Dynasty Royal Mail Company. The mail company mainly runs some super long-distance postage routes and handles remittances and other businesses. After all, it has the name of the Ming Dynasty Royal, so everyone naturally trusts the word "royal". If the money is handed over to them to remit to other places, everyone will feel at ease.

The Royal Mail Company of the Ming Dynasty has its own mail truck and mail ship. With the support of Li Guodong, shipbuilders finally built a kind of fast ship called Clippers in the past few years, which is specially used to carry out trans-ocean routes.

If express delivery companies only handle domestic business, then mail companies mainly focus on international business. In addition to transporting mail, those mail ships are actually also passenger ships.

Zhang Liang's letter was sent to the Shanghai car manufacturing factory through a express delivery company.

"What? Is it necessary to obtain the right to produce bearings and pass the approval of Duke of Chu?" Qi Bansun was very surprised.

However, he still asked someone to find Li Guodong. Chen Zilong, who had a close relationship with Li Guodong and had a friendship with the Qi brothers, naturally took on this task.

In the Forbidden City in Nanjing, Li Guodong had an intimate conversation with Zhang Yan in Kunning Palace. Although he had crossed the boundaries, he did not reach the relationship between the queen and the head of the face as rumored in some tabloids outside. It was just a normal friendship relationship. At most, it was just a hand-holding. After all, Zhang Yan is not Li Guodong's dish, and there is also a princess who is his dish.

Chen Zilong arrived at the palace gate and asked someone to go in and report. Not long after, Li Guodong came out.

"Why did Wozi come to find Li today?" Li Guodong smiled and patted Chen Zilong on the shoulder, "Let's go, we haven't seen each other for a long time, let's have a few drinks together."

When I walked into the largest restaurant on the shore of Xuanwu Lake, the two of them booked a private room. This restaurant is actually the industry of Dadewang. When talking about things here, you can not only appreciate the scenery of the lake, but also be very safe. Who knows which of the guys in the store is Jinyiwei?

After drinking a few glasses of wine, Chen Zilong talked about the Qi brothers.

"It turned out to be the Qi brothers. Li had heard of them. They mortgaged all their land and borrowed a sum of money to start an industry in Shanghai. This is a good thing. Our court encouraged the land gentry to transform." Li Guodong said with a smile.

The transformation of land gentry is definitely a good thing, and this is something that Li Guodong has always supported.

Chen Zilong looked at him with a difficult face: "But they are facing problems now. Their car manufacturer plans to produce a track carriage, which is out of their contract with the Foshan carriage factory. The bearing factory in Guangdong cannot provide them with more bearings, so they want to produce their own bearings. But the bearing factory refuses to spread the technology."

Li Guodong smiled and said, "Don't underestimate this bearing. Small bearings are a weapon of the country! This technology will definitely not be spread out. But I can still trust the Qi brothers. Let's do this. As long as they promise not to spread the technology and strictly observe the confidentiality system, if a craftsman learns the technology and runs out, it must be severely punished. As long as they can do this, I can write him to Guangdong."

"Please rest assured, they can definitely do it." Chen Zilong said.

Li Guodong was not worried about the Qi brothers. In the original time and space, the Qi father was a loyal and martyr in the Ming Dynasty. When the Qi brothers arrived in the Qing Dynasty, they were also interested in the Ming Dynasty and ended up in a destruction. Such people would definitely not do anything to be sorry to the Ming Dynasty. It was just that technology was not strictly confidential, and it would inevitably be leaked without strict confidentiality measures. Take Li Guodong's six-pound cannon field cannons and twelve-pound field cannons, the Qing Dynasty already knew how to cast these two types of cannons.

Bearing technology is difficult to leak because of the core technology of materials. Don’t underestimate bearings. Only with this kind of thing can the cannon be truly running.

Li Guodong said again: "But producing bearings is not simply transferring iron beads into the bearing. It also requires a complete set of technology. For example, steelmaking technology, otherwise the bearings made will not be useful. Within a few days, all the beads inside will be broken. Even if you use iron pillars, it won't be enough. It won't be worn for a long time. If they are willing to let them come to Nanjing to meet me by themselves, I can open an additional steel factory in Shanghai to provide them with bearing parts."

Chen Zilong returned to Shanghai and said Li Guodong's words to the Qi brothers. The two brothers expressed their gratitude to Duke Chu, and at the same time promised that the technology would not be leaked.

However, the production of bearings is not that simple. The balls or needles inside must be made of fine steel, and components that are easily worn must be made of refined steel. Pig iron and cooked iron are not good at all. Pig iron is easy to break, and cooked iron is too soft and can easily be ground and deformed.

Therefore, to build a bearing factory in Shanghai, a steel factory is also needed.

The most important thing is that the creativity of the Qi brothers' track carriage moved Li Guodong. He decided to increase the scale of steel production to lay the foundation for the future construction of railways.
