[Inside the steelmaking plant]

"Yes, keep pressing, at this angle." Zheng Kezang directed the craftsman to operate the hydraulic press.

Bang bang bang, the hydraulic press hit the steel block underneath, and for a moment, sparks flew everywhere.

Craftsman Lao Su was also beside him, "Your Highness, this is not the right iron. The quality of the steel is extremely high, its strength and ductility are much better, and it is not as brittle as ordinary iron."

"Since this steel has such good performance, in addition to being used to make gun barrels, it should be used in other places, such as armor. Our armor in Dongning is made of pieces of armor and then woven with leather ropes, but in the West

There is a kind of plate armor, the whole body is made of steel, even strong bows and powerful crossbows cannot penetrate it." Zheng Kezang thought for a while.

That's right, Zheng Kezang plans to strengthen his men's protective capabilities.

Previously, both the Youth Battalion and the Guards were strictly unarmored armies.

The effective range of a flintlock gun is similar to that of a bow and arrow. Even with the blessing of sweet gunpowder, the flintlock gun produced in the Ming and Zheng Dynasties has a longer range.

If you have to face Tatar bows and arrows in the future, just in case, you'd better wear armor.

"Your Highness, are you talking about the heavy armor of the red-haired Yi?" Su Laocheng asked. Yizhou Island has been dealing with the Dutch and Spanish for many years, and Su Laocheng remembered that he had seen it before.

[Please pay 5 Brilliance Points.]

The famous French cuirassiers wore it to fight, and it was not heavy, so it was very suitable for facing the Tatar army that was half firearms and half cold weapons.

Among them, Yinli iron ore occurs in shale, limestone and granite, with the highest grade reaching 70%, and resource reserves of 500 million tons. The highest grade iron ore is Ping'an Daojiechuan iron ore.

When faced with the choice between the Northern Expedition and the southward expedition, Zheng Kezang chose to go south, which was also the last wish of Mr. Guo Xingye.

But instead, the Spaniards carried out the third massacre of Chinese immigrants in Manila.

Korea is rich in iron ore reserves. The buried amount of iron ore is more than 9-11 billion tons, mainly including magnet, limonite and hematite.

Since he wanted to make breastplates, he had to find a way to stockpile more iron ore with his father-in-law.

Soon, Zheng Kezang gave up and decided to go shopping in the system mall.

Immediately, the drawing suddenly appeared in Zheng Kezang's hands, and he was used to it.

However, if you want to go shopping with Spain, you need to think carefully whether it is worth it.

As soon as he said it, Zheng Kezang said to the system: "Please give me the iron ore distribution map in Asia."

[Already paid, the balance of brilliant points is 55.]

The iron ore reserves in the Biko area of ​​the Luzon Islands amount to 140 million tons, and the iron ore reserves in Tagpo, Sabo-An and Longnao, and Bayes City in Negros Oriental Province are 89,000 tons.

Zheng Kezang was not in a hurry to leave, he wanted to see the effect of their creation.

After hearing the news, Guo Xingye was furious and decided to send his troops south to conquer and avenge the people of the Ming Dynasty.

However, Zheng Kezang discovered something new: French breastplates and cuirassier helmets. A complete set of blueprints only costs 5 Brilliance Points.

"Take it." It's only five o'clock, no problem.

"Your Highness, promise to complete the task." Lao Su replied.

Zheng Kezang walked around the system mall and decided not to buy plate armor, because in the face of a heavy matchlock gun, although plate armor could prevent bullets from penetrating, it could not relieve the impact of the bullets.

Old Su was full of confidence. He had secured the two hundred taels of silver and immediately arranged for people to start working.

The breastplate is generally composed of two front and rear decks. The main material is iron, with a polished surface. It weighs about nine to ten kilograms. The buckles and rivets are made of brass and are connected by belts.

It is mostly distributed in the surface layer and is easy to mine. Its reserves are close to the top ten in the world.

"Your Highness, how many sets are you going to make in the first batch?"

"Yes, that's it. Just wait." Zheng Kezang picked up paper and pen and decided to draw a wave of plate armor by hand based on his impressions of Europa Universalis and Mount & Blade.

Typical mines in Goryeo include Musan Iron Mine, Deokhyeon Iron Mine, Liyuan Iron Mine, Jiechuan Iron Mine, Ucheon Iron Mine, Haesheng Iron Mine, Ohryong Iron Mine, Einli Iron Mine, Zainyeong Iron Mine, etc.

"I am willing to serve His Highness." Old Su looked at the drawings and thought: This is too simple. With a magical tool like a hydraulic press, you can make as many sets as you want.

Just decide it is it, redeem it, system.

The most important thing is that it is simple to make and if you are skilled, it is not a problem to make hundreds or thousands of sets a day.

"Can we complete the task of building 1,500 sets within ten days?" Zheng Kezang thought for a while and found that this number was more reasonable, so he asked.

There is also a lot of iron ore in Korea in the north, and the quality is pretty good.

"If you complete the task on time, you will be rewarded two hundred taels of silver to the steel mill." The emperor did not lack hungry soldiers, which satisfied Zheng Kezang and gave him a big reward.

The more Zheng Kezang looked at it, the more excited he became. There are so many iron ores, and you can't control them in Little Korea. The water here is too deep, so I'd better let Uncle Zheng do it.

Besides, by the time they came over, Zheng Kezang was already fully developed. They knew that Zheng was a pioneer in the fight against imperialism and was the least cowardly of Western colonizers.

With the continuous beating of the hydraulic press, a pair of breastplates gradually took shape, and Zheng Kezang felt relieved.

Yizhou Island has basically no iron ore resources and relies entirely on imports. Building a site with iron ore is the top priority of the next strategy.

The huge impact force often causes the guard plate to dent inward and cause damage. The vibration generated when the bullet collides with the plate armor can also cause serious damage to the human body, and the plate armor gradually declines.

The Domac iron ore deposit in Camarines Norte Province in central-eastern Luzon Island has an iron ore resource of 10 million tons.

After a wave of operations, [Brilliant Points Balance: 60]

Unless the Qing Dynasty was slow to respond, it would be relatively feasible to launch a blitzkrieg to conquer Goryeo and wait for a year and a half to train Goryeo's servant army.

"Old Su, these are the drawings of the breastplate and helmet. You can understand how to make them at a glance, so I will leave it to you." Zheng Kezang handed the drawings to Old Su.

Quickly picking up the drawings and studying them, he found that the nearest Luzon Islands had a lot of iron ore.

I remember that it was in 1662 that Guo Xingye ordered the Catholic priest Li Keluo to go to the Philippines to submit his credentials to the Spanish Governor, condemning his crime of killing and plundering Chinese immigrants, and strictly ordered him to change his ways and bow down to pay tribute to the Ming Dynasty.

After careful consideration, we are still unable to attack at this stage. It is better to attack the Luzon Islands directly. Spain does not have much military power in Asia. If we capture Luzon, it is impossible for the Spanish fleet to sail all the way from Europe.

But there is another problem. If you capture Goryeo, it will be directly connected with the ancestral land of the Qing Dynasty. It will definitely be difficult to fight in the early stage because the Qing Dynasty has too many troops.

On the one hand, he subsidized and resettled the Chinese immigrants who fled from Luzon to Yizhou Island. On the other hand, he organized and prepared the Ming and Zheng Navy, and sent people to secretly contact the Chinese immigrants in Luzon, so that he could cooperate internally and externally to attack the arrogant Spaniards.

But when the troops were dispatched, Guo Xingye died suddenly, and the crusade against the Spanish was abandoned.

But it doesn't matter. Let him, Zheng Kezang, fulfill the last wish of his ancestors. Once Feng Xifan and other rebellious officials and traitors are defeated, it will be the turn of the Spanish colonists.

If you don't avenge the Chinese immigrants, you will be sorry for the country's surname.
