During this period, the iron fried in the iron furnace was actually some wrought iron, and of course, with a little luck, you could also fry steel with a higher carbon content than wrought iron.

It's just that during this period, the steel speculation cannot control the measurement, and it all depends on the luck of the speculators.

"You are waiting for me to make iron for the Ming Dynasty, working day and night, and I thank you on behalf of the Ming court officials." Liu Yu actually saluted Wang Qing and other craftsmen.

"My lord, I can't help it." Wang Qing panicked and hurriedly waved his hand.

"Since charcoal smelting can smelt good iron, then in the future, the major states and societies in Luzon will pay tribute and taxes to the Ming Dynasty, and allow them to replace them with local Luzon wood." Liu Yu instructed the soldiers on the side to write it down.

The smelter of the Ming Court was also just built by the Ming Court, although the Ming Court attached great importance to it, but it was obvious that it would smelt iron for a while and a half, and its production capacity could not keep up with the demand of the Ming Court.

"It looks like we still need to import iron from the mainland!" Liu Yu and his entourage walked out of the iron-smelting plant, looked at the busy workers, shook their heads and smiled bitterly.

"My lord, didn't the king say that the mainland uses more coal for iron smelting, and the quality of the iron smelted is not good?" Huang Youde, who was on the side, frowned and asked when he heard this.

"Naturally, it's not for your firearms department to make cannons." Liu Yu smiled.

"Now that the Ming court has set up a county community in Luzon to reclaim the wasteland, how many iron tools do the farmers and the people need, is it possible that the iron materials that my Daming smelter has worked so hard to cast will be wasted on casting agricultural tools." Liu Yu looked at Huang Youde in front of him with a smile on his face and said comfortingly.

"That's right, the best iron smelted by my Daming Dynasty will naturally be used for casting firearms." Huang Youde breathed a sigh of relief.

If the quality of the iron sent is not good, and the firearm made by the firearms master is inexplicably blown up, then there is really no place to reason.

"But you firearms craftsmen should also remember that if there is an iron cast cannon, its quality must not be as good as the bronze cannon, I don't ask how good the Daming iron cannon is, but it must be comparable to the iron cannon sold to us by the East India Company." Liu Yu admonished.

After all, copper is more expensive than iron, and casting one copper cannon is worth casting five iron cannons.

The Luzon Ming Army is naturally not a local tyrant, and it must live a careful life.

Naturally, it is necessary to use low-cost iron cannons.

The artillery of this period, especially the army, was basically copper cannons, rather than iron cannons that were widely used by the Ming army.

The reason is naturally that iron is easy to explode, and it is not as good as copper cannons.

In particular, the Western armies basically use copper cannons, of course, it is also related to the fact that their iron cannon casting technology is not as good as copper cannons.

The only thing that is out of the ordinary is the UK.

Like the Luzon Ming Army, the English people also used charcoal smelting instead of coal smelting used in European countries.

Therefore, the quality of the iron cannons cast by the English people was not much worse than that of the European copper cannons of the same period, but the price was much lower than that of the copper cannons.

"Remember, villain."

Huang Youde naturally understood what Liu Yu meant.

As soon as I arrived at the wharf, I saw a group of merchants hurrying here.

"My lord, I found you." Su Langqing ran out of breath, and hurriedly wiped the sweat on his cheeks with his cuffs.

"What?" Liu Yu glanced at the land and sea merchants who came over.

"My lord, I just learned the news from the Luhai Trading House that the Zhenla people are attacking Dongpu." Su Langqing said.

"The land and sea merchant ships are mostly in Hoi An and other places these days, so they were the first to learn the news and rushed back to Luzon." Su Langqing hurriedly explained.

"It doesn't matter." Liu Yu also learned the news from the epidemic avoidance not long ago.

Not long after, Xiao Wu also learned the news and hurriedly came over to discuss with Liu Yu.

"This Zhenla people dare to invade Dongpu, they really ate the bear's heart and leopard gall, and we should immediately send troops to Dongpu." As soon as Xiao Wu arrived at the official residence, he said angrily to Liu Yu.

"The Zhenla people are brutal, slaughtering my Ming people, if we don't send troops to Dongpu, where is the majesty." Many generals on the side echoed it.

Now the Ming court in Luzon has been peaceful for a long time, except for the occasional sea to fight pirates, there is no war.

A large number of firearms and ordnance were almost useless, and a large number of newly recruited soldiers had not experienced actual combat, so when they learned that the Zhenla people had invaded Dongpu, these generals asked for help.

"Wang Li, a merchant from the land and sea, has already said that Yang Yandi has moved, and now Yang Yandi must have led his army to Dongpu." Liu Yu motioned to the generals to calm down their anger.

"Master Hou, I'm afraid that the Dongpu disaster will be quelled by land and sea merchants alone." When Xu Bin heard this, he reminded Liu Yudao.

"I also learned about the Ming people in Dongpu from the merchants, this time Zhenla invaded Dongpu, I am afraid that it was instigated by Guangnan, and only the Ming people in Dongpu and other places are afraid..."

"Shuishi Town is stationed on Dayu Island, and Fubo Town is also stationed in Bataan, Laoag and other places, and ships can be sent to Dongpu." Xiao Wu obviously wanted to intervene in the Dongpu war.

"After the Tatars entered the Central Plains, a large number of Ming people went south to Annam, if we can send troops to rescue, we will be able to take Dongpu and other Shuizhenla regions, and then with Luzon and Dongpu and other lands, my Ming court will definitely be able to dominate the South Seas." Xiao Wu pointed to the boundary of Annan on the sea chart, revealing a greedy look.

"My lord, if you send troops to Dongpu, Fubo Town can send 30 warships and 1,000 sailors." Li Shi hurriedly said.

"My lord, if you can take it, recruit Han people to develop it, you will definitely be able to become a land of fish and rice, and then the Ming Dynasty can directly obtain a steady stream of food and soldiers from Zhenla, and if you return to attack the Qing court in the future, we can also get a place to train soldiers and hoard food." Xu Bin continued to persuade.

The power of Luzon's money and grain is in the hands of Liu Yu, if Liu Yu does not agree to send troops, then it is useless for Xiao Wu and others to agitate.

Xu Bin's words are also right, the water is really fertile for thousands of miles, and if it can be developed well, it will definitely become a land of fish and rice.

If the Ming court counterattacked the Qing court, the most important thing was money and food.

At the beginning, the national surname returned to attack the Qing Dynasty, relying on Xiamen, Quanzhou and other coastal conveniences, opened benevolence, righteousness, etiquette, wisdom, letter and water road five merchants, Quanzhou commercial bank leader Zeng Dinglao, Wu Qiniang, Gong Sunguan, Gong Meiniang as the leader.

At the same time, there are five major trade routes and five merchants in Hangzhou and other places.

With these top ten commercial houses, a steady stream of silver taels has been obtained, which is also the fundamental reason why the surname of the country has been able to resist the Qing Dynasty for decades.

And now Liu Yu has established the Four Seas Commercial Bank in Luzon, and has attracted the Chinese merchants in Nanyang for his own use, in fact, it is the same as the original practice of the country's surname, that is, to obtain a steady stream of silver taels and materials.

But the most important grain was not something that merchants could simply trade.

In particular, tens of thousands of troops are drawn at every turn, and the amount of grain and grass required is simply astronomical.

A very important reason for the failure of the Zheng army to resist the Qing Dynasty was the lack of a grain production area that could support an army of more than 100,000 people.

In many cases, the Zheng army was just a mobile war at sea, and it only controlled some counties and towns and islands along the coast, and it could not support many people at all, let alone maintain the daily food and drink of a huge army.
