Level 4 Flame Rune Stone can definitely improve the combat effectiveness of a single soldier.

However, the upper limit of the improvement depends on the strength of the wearer and the level of other equipment on the wearer.

For example, Xia Liz is now a level 3 awakening knight, and Xia Liz does not have any equipment with flame enchantments, so the level 4 Flame Rune Stone can only be improved on the basis of Xia Liz's own level 3.

This improvement efficiency is far less than that of a person with a full set of flame enchantments and flame magic martial arts or flame magic spells.

Therefore, if you want to maximize the improvement efficiency of the level 4 Flame Rune Stone on an individual, either fill Xia Liz with full body flame enchantment equipment, or give the level 4 Flame Rune Stone to Anne Loris.

However, Anne is not one of us yet, and at best can only be regarded as a reluctant captive.

Since Annie is not one of them, Luo Wei certainly can't use the Level 4 Fire Rune Stone on Annie.

Besides, even if Luo Wei is willing to give it, Annie, who is a proud noble lady, may not want it.

Annie's own equipment is actually very good. Her Level 5 magician robe, ring, necklace, and staff are all inlaid with magic rubies.

This kind of magic ruby ​​is theoretically the same as the rune stone, except that the rune stone is engraved on the meteorite, while the ruby ​​is engraved on the used dragon crystal.

The magic ruby ​​only has a bonus to magic spells and has no effect on knights.

The cost of magic ruby ​​is also higher than rune stone, and only real nobles can afford it.

The magic rubies on Annie are all Level 5, and Annie naturally doesn't like the Level 4 Fire Rune Stone. If she wants to make the best use of this Level 4 Fire Rune Stone, then the best way is not to inlay it on individuals, but to use it in industry.

Previously, Luo Wei had done several experiments with the Level 1 Flame Rune Stone that he had repaired himself, hoping to improve the efficiency of the block furnace in the blacksmith shop through the rune stone.

However, because the level of the Level 1 Flame Rune Stone was too low, and Luo Wei only had a Level 1 Flame Element, he tried several times but did not see much improvement. Instead, he broke several Level 1 Flame Rune Stones.

But Luo Wei was not distressed.

Luo Wei always felt that using magic to improve industrial efficiency was the right path in the Regan world.

Problems that science could not solve, magic could.

Now that Luo Wei had a Level 4 Flame Rune Stone in his hand, he could try to improve the efficiency of the block furnace again.

As long as it could be used, this Flame Rune Stone could be used as a carrier to increase the temperature of the block furnace,

so that the high temperature in the furnace exceeded 1200 kilo degrees.

1200 kilo degrees is the threshold for refining molten iron. This value is converted into the value of the earth world, which is about 1500 degrees Celsius.

The block furnace in Meiling Valley has actually been improved. The air blast is driven by a waterwheel, and the charcoal is made from expensive oak wood. However, due to the lack of combustion aids for modern industry on Earth, the furnace temperature of the block furnace can only reach about 1000 kilometres at most.

Although Gerlan, as a senior blacksmith, has a very good ironmaking skill, and the block furnace can occasionally smelt some pig iron, but in most cases, it can only smelt semi-solid sponge iron that needs secondary forging.

This kind of smelting will cause a lot of waste, not only manpower, but also crude iron ore, and the smelted sponge iron also has a lot of impurities.

When the blacksmith shop in Meiling Valley just started, because a large number of ironware was urgently needed, it didn't matter if the quality was a little poor, the main thing was to go for quantity.

Now, with the basic popularization of ironware, everyone has several pieces of ironware, and the weapons and equipment of the bell-ringing army are all pure ironware, the cost-effectiveness of the semi-solid sponge iron produced by the block furnace is very low.

Moreover, there is only one excellent blacksmith, Gerlan, and the others are all apprentices who have not yet completed their apprenticeship. If the blacksmiths are used to purify the pig iron, the quality and output cannot meet the needs of Merlin Valley.

Especially since they are about to fight a tough battle with Pace, it is even more important to have high-quality ironware.

As long as the iron can be smelted into molten iron, not only can a large number of impurities be removed, but also steel with higher hardness can be forged.

The existing steel in the Regan world is forged with a top-secret formula.

But even if he doesn't know the formula, Luo Wei can guess that there must be magic or magic in the combustion aid.

So, from this point of view, Merlin Valley Manor can also develop its own magic steel.

Even if it can't reach the level of the dwarf dragon steel, it can at least be better than ordinary ironware.

A shield made of magic steel can defend against the slashing of iron weapons and the shooting of arrows, while arrows made of magic steel can penetrate the opponent's iron armor and shield.

If the weapon material is upgraded by one level, the overall combat power can be increased tenfold!

As a Chinese in the Earth World, Luo Wei is very clear about the principle that a craftsman must first sharpen his tools before he can do his work well.

If you want to defeat Pace and the entire Marigold with a small bet, the weapons and equipment must be strong!

Now, the key to improving weapons and equipment is to smelt molten iron to remove impurities, and the key to smelting molten iron is the combustion aid.

Luo Wei's idea is to combine the 4th level flame rune stone with oak charcoal to form a magic combustion aid. Why use oak charcoal instead of coal?

Because charcoal is worse than coal in steelmaking.

The Earth uses coal, and because of industrial coal washing, industrial coal itself does not have too many impurities. In the Regen world, coal still has a high impurity content. Not only is the combustion efficiency not as good as charcoal,

its own sulfur content will also affect the smelting of pig iron.

In addition, the reason why the Earth uses coal instead of uncharcoal is because the cost of charcoal is too high to burn.

Melting molten iron requires a lot of combustion aids. In order to protect the environment, forest trees cannot be cut down at will. The cost of wood is much higher than that of coke.

But there is no such problem in the Regen world.

Especially in the Merrill Valley backed by the Black Moon Forest.

Even if you set a fire to the Black Moon Forest and want to burn the entire Black Moon Forest, it will not be burned out for hundreds of years. The wood resources can even be described as inexhaustible.

As for the principle of steelmaking, it is actually very simple. When the crude iron ore is smelted into molten iron, it is taken out of the block furnace with a crucible and transferred to the blast furnace for carbon reduction.

The difference between pig iron and steel lies in the carbon content.

To make steel, you must first make iron, and charcoal and coke are necessary to help with combustion. The molten iron will contain a lot of carbon, so after the molten iron is made, it needs to be reduced by carbon reduction.

Although there is no industrial reducing agent on Earth to reduce carbon, it is not a big problem with the waterwheel bellows.

The key is how to make the level 4 flame rune stone continue to play the role of flame combustion.

It is not enough to rely on the amount of infusion to turn stone into gold.

Luo Wei has tried many times before. Turning stone into gold is only useful for broken rune stones, and excessive infusion will cause the rune stone to explode.

In order to maintain the pure magic flame released by the flame rune stone to remove impurities from the crude iron ore and reach a high temperature of 1200 kilos to melt molten iron with almost no impurities, you must have a magician who can control the flame.

What a coincidence, isn't it?

Isn't Annie a level 5 flame magician?

Meiling Valley does not support idle people!

What's wrong with the Earl's daughter? Even if Princess Lillian, the pearl of the Soladin Empire, comes, she has to work for me!

Just as Luo Wei was about to get up and look for Annie, he saw the Earl's daughter, dressed in a gorgeous aristocratic robe and with an elegant temperament, walk in with a proud look on her face.
