Report to the lord, Zhang Hongfan's army boarded a ship from Chaozhou Port and went to sea, and its whereabouts are unknown. ”

"Probe!"

"Report to the lord, the Yuan soldiers abandoned the city, and Meizhou Chaozhou did not leave a single soldier.!"

"Probe!"

The scouts sent out sent back one after another amazing battle reports, Guangzhou City has begun to prepare to resist Zhang Hongfan's army, the people of the main towns of Panyu have been transferred to most of the people, and the township army to resist the Yuan has set up a stronghold in the mountains.

However, Zhang Hongfan's army of more than 100,000 troops left Chaozhou and boarded ships to go to sea, so naturally it was a waterway offensive to launch, and the naval ships on Hong Kong Island and the Pearl River port were on alert, and the equipment of the firearms battalion was also stationed at the wharf, and Hongyi cannons were erected for shore defense.

However, after five days, no warships of the Yuan army were found on the sea, and later I received news from people who went out to sea to fish, and I had seen a very large fleet on the blue sea. You can't be wrong on the vast sea, and there can be no other fleet, whether Zhang Hongfan belongs or not, but it must be the soldiers and horses of the Yuan Dynasty.

Zhang Zhensun was very nervous in the city of Guangzhou, and there were more than 1,000 fast horse scouts galloping out at most times, scattered in all directions, scouting the possible enemy. A tiger lying on your west gate is much more reassuring than a disappearing tiger, in addition to looking for Zhang Hongfan's main force, but also to prevent the possibility of Li Heng attacking again after the whole army.

Zhao Tianyou traveled back and forth between the island and Guangzhou City, and on the one hand, he had to participate in the military intelligence meetings in Guangzhou City, and he also had to arrange for the adjustment of the firearms battalion stationed in Guangzhou City at all times. Since the integration of large merchants near Guangzhou, there has been a stable supply of coal and iron ore produced in the north, the output of gunpowder and refined iron has repeatedly reached new highs, and the establishment and personnel of the firearms battalion have also increased several times.

Zhao Tianyou and Du Hu discussed plans to expand it into nine battalions, form three regiments and combine them into one division, and form a more efficient contingent with distinctive combat characteristics according to the variety of weapons and the refinement of equipment. In order to effectively distinguish between the firearms battalion and the nostalgia of Zhao Tianyou's past, this first professional unit equipped with firearms was born, and the name was also quite imposing, the First Division of the Second Artillery Corps.

Although they are now all entry-level artillery and crude low-level explosive weapons, their status is similar to that of the Second Artillery Group in Zhao Tianyou's era, and they are also the foundation of a country, and from the very beginning of their birth, they have shouldered the heavy responsibility of ensuring the fundamental survival interests of the Chinese nation.

The output of Hongyi cannon was deliberately reduced by half by Zhao Tian, leaving half of the productivity and technical personnel, working overtime to overcome the manufacturing difficulties of the Franc cannon, and doing his best to meet the requirements put forward by Zhao Tianyou.

For the Franc machine, Zhao Tianyou named it the sub-mother cannon, because the power of the Hongyi cannon is huge, if the power of the sub-mother cannon is not enough, it is equivalent to wasting limited productivity out of thin air. This time, Zhao Tianyou put forward three standards, if the process is not met, it is strictly forbidden to produce and cast on a large scale.

The unified standard of the cannon body of the first mother cannon, the caliber is divided into three inches and five inches, which requires a polar error to facilitate the production of standard caliber flowering shells. Different from the nine-inch huge caliber of the Hongyi cannon, the technological requirements for the flowering cannonball have been improved a lot, and the sub-cannon charge itself is small, and the caliber of the cannonball must be tightly matched with the caliber of the mother cannon's bore in order to achieve a more effective range.

The assembly line production process of the second sub-cannon should be exactly the same, and after any sub-cannon is loaded with shells, it can be filled and fired on any mother cannon, and the error of the degree of fit requires eight or nine out of ten, that is, to achieve 80 percent of the general characteristics.

The third is to optimize the aiming performance of the gun body, which also requires a mature gunner to master the scale of the three guns, and from the fourth shell onwards, half of the hit rate is required. These requirements are not too much, and the requirements are not excessive, but after they were done, more than a dozen groups of hundreds of skilled craftsmen failed.

Zhao Tianyou was not in a hurry at first, and asked them to continue the experiment after mentioning a few key points, the current state of war is mainly defensive, and the Hongyi cannon is enough to support it, but the sub-mother cannon came out a day earlier, and Zhao Tianyou is equivalent to one more trump card in hand.

Hong Kong Island's industrial production relies on a large amount of materials and huge manpower investment, and if Zhao Tianyou's ability to manage money alone, he would have been unable to make ends meet and owe a lot of debts. Relying on the signboard of duty-free transactions on Hong Kong Island, merchant ships from several countries have come to Hong Kong Island tentatively to trade, and more than a dozen commercial banks in Guangdong and Guangzhou, which have already settled on Hong Kong Island, have made a small fortune by virtue of their first-mover advantage, and have set off the business on Hong Kong Island at once.

At present, large and small merchant ships and cargo ships call at the port of Dapo Sea every day, and in addition to the goods purchased by Hong Kong Island itself, more than half of the overseas trade volume attracted by duty-free is already increasing.

The project focuses on Hong Kong Island, where arms research and development is the first to make money, and the trade in high-quality iron, which is a by-product of the non-military industry. The steel pulley hinges are very strong and durable, and the primary wheel bearings can greatly improve the speed and comfort of the carriage, which are purchased at high prices by merchants in India and big food countries, and Zhao Tianyou does not care if it is imitated and produced back.

It is already a semi-industrial assembly line type of steelmaking and ironmaking, and the huge cost advantage has been reflected in every piece of ironware, especially this kind of production tool composed of different parts and groups, the cost is so low that others can not imagine. Hong Kong Island is not worried about others taking it back to copy, because according to this quality standard in the production, the cost is not lower than buying from here, the biggest secret is the standardized assembly line production, and it is not something that can be stolen at a glance.

Zhang Hongfan's army boarded the ship and went to sea, Zhao Tianyou, who was the most nervous at first, but later thought that this barren land had just been developed, and it was impossible to attract Zhang Hongfan's attention.

Except for Zhang Shijie, who is wandering around Leizhou, I am afraid that there is no second target in this world that can make him kill him in such a hurry. There are many contents in Zhu Qing's secret letter, except that Pu Shougeng happened to deliver 300 new warships, which must be filled with about 100,000 troops, which Zhu Qing did not have, there were other small abacus.

Li Heng returned to Wuzhou to recuperate after the defeat of Guangzhou, at this time he also got the information that Zhang Shijie was wandering in Leizhou, although the two cities of Gaozhou and Yulin were still in the hands of the Song army at that time, but if the army led all the way south to Leizhou, it would be easier than shaking Guangzhou to save worry and effort, and the credit was much greater.

What made Li Heng hesitate was that he couldn't judge Zhang Shijie's movements, if he killed him, Zhang Shijie got on the boat and ran away, let Zhu Qing pick up a bargain at sea, this credit can be given to others, it is better to continue to attack Guangzhou steadily.

At this time, the military order of Prime Minister Boyan, the commander-in-chief of the invasion of the Song Dynasty, arrived!
