After a series of tests, beheading two sheep and destroying a set of paper armor, Luo Ming couldn't help but laugh.

Both of his masters were martial arts masters, and their families had a wide collection of weapons, some of which even belonged to the category of national treasures - God knows how they brought back to the Celestial Empire the national treasures of the countries that were forbidden to leave the country.

All in all, Luo Ming has played with dozens of various swords near the water, such as Uzi steel, jade steel, and hundred forging steel, although he can't build it, but the feeling of the hand is still relatively familiar.

And now the sword strip in his hand, although it is not as good as the best of the best, is already a kind of steel, which is higher than the average of weapons in this era - except for the nobles and the strong who will use steel weapons and even enchanted weapons, the weapons of ordinary soldiers can only be said to be wrought iron.

Of course, wrought iron cannot be looked down upon, and even the blade of wrought iron may cut off the arm of a person who does not wear armor with a sword, or stab him in the heart.

But there is naturally a gap between wrought iron and steel, although in terms of Luo Ming's feel, this gap is not big, but there is already such a good start, and then as long as the process is slowly improved and experience is accumulated, this gap will definitely be expanded.

The armor also underwent a series of tests, and finally confirmed that it was one-third stronger than ordinary wrought iron armor at the same weight.

In other words, making armor from this steel can reduce the weight to three-quarters of wrought iron armor while ensuring the same defense.

Of course, this result may seem mediocre. Not to mention the luxurious armor that is enchanted or mixed with pure gold, even if it is pure steel armor, there are fine products that are three times stronger than wrought iron armor, that is, on the premise of ensuring the same defense, the weight is only one-third of that of wrought iron armor.

But those are high-quality products, expensive to build, require the patience of very experienced craftsmen to build, and the process is also very cumbersome.

However, the steel produced by Luo Ming now has a big advantage - compared with the traditional process, it requires less manpower, the cost is lower, and the cost is more than 40% lower if you save labor costs.

In addition, one of the major advantages over traditional processes is that it can be mass-produced!

Today's steel production is almost entirely handmade in small workshops, with low yields and the need for experienced craftsmen.

For Luo Ming, these constraints can be said to be almost non-existent! His steelmaking furnace can produce up to 50 kilograms of steel per day, or 18 tons a year without the constraints of raw materials!

In the 21st century on the earth, some steel mills can produce more than 18 tons of steel a day, even in 1840, the annual output of Britain was 800,000 tons of steel, but in this era it is completely different-

The eighteen tons of steel were spread evenly among the 1,200-strong army, and each soldier received an average of fifteen kilograms, which was almost enough to arm every soldier to the teeth, considering that the weapons could be made using the steel clamping method to save steel.

Of course, resources are a big constraint. If you want to continue to produce at full efficiency, you need to provide sufficient raw materials.

Luo Ming's more than 10,000 men seem to be a lot, but there are still some deficiencies in opening iron ore, and they can probably only import iron ore and iron ingots from outside.

As far as he knew, even the county watchman's domain produced about that amount of iron in a year.

In any case, its maximum output has reached such a strong level, which fully reflects the superiority of the idea of industrialization.

It's not like he, a traverser, came up with some ideas and could quickly get it done with the help of a few craftsmen.

Paper armor is okay, and bronze cannons are relatively stupid and coarse, but steelmaking technology is a whole set of processes and technical specifications, and it cannot be achieved overnight. Even if it succeeds, it will take at least five or six years.

In this regard, Luo Ming did open a plug-in called "His Highness Black Sun, please help me".

His Highness the Black Sun already had a vast knowledge and keen thinking that far surpassed all mortals, coupled with the enlightenment of the otherworldly thinking of the traverser, almost two months ago, he finally deduced this steelmaking process.

It took two weeks to build a steelmaking furnace and prepare various facilities, and then it was not until the day before yesterday that the first furnace of qualified steel was produced.

Fortunately, most of the products of steelmaking failure can be returned to the furnace for re-refining, otherwise the process would have to bankrupt Luo Ming.

This is also one of the great advantages of the new steelmaking method - it can directly put qualified iron into steel in batches.

In other words, even if Luo Ming buys iron from outside, he can make a profit by directly refining it into steel and selling it.

Of course, Luo Ming does not plan to make money on a large scale by this method - it is enough to sell a small amount of steel products, and if you sell too much, it will definitely attract greedy vultures to try this new process.

In fact, even the artillery has people to inquire about the news. It's just that Luo Ming cleverly introduced it as a siege equipment, saying that it was a special trebuchet, and exaggerating its cost of use and use, so no one insisted on buying it for the time being.

This is also due to the fact that his guns can only fire solid or shotgun, and the rate of fire is very average...... If a rifled cannon with a fixed grenade and a brake is built, as long as it is used once on the battlefield, it will definitely not be able to be so perfunctory.

Luo Ming didn't think that he would be able to cover up the news forever, but as long as he covered it up for a few more years.

He has already drawn up a series of development plans that will give rise to a strong force in five years at most. Even if these secrets are completely exposed at that time, he can break those outstretched dog paws, so that anyone can put away their cunning heart.

If nothing else, most of the plans will be completed in the third year.

And these plans have also been divided into smaller one-year sub-plans, which he is confident will double his military strength if he can complete two-thirds of this year's sub-plans.

Ichiban...... Anyway, in his estimates, a year later, even if he encountered an army of 5,000 people in the field, Luo Ming was confident that he would defeat it!

In this regard, it is only necessary to come step by step, and in addition, it is economic construction. If we go all out and neglect economic construction, we will be able to get away with it for a while, but in the long run, we will certainly have problems.

The explosive power of black powder is actually not comparable to many magic and alchemy creations, but relatively speaking, its cost is much lower, even Luo Ming can use it on a large scale.

Since he had this kind of weapon in hand, he decided to do something unimaginable to ordinary people.
