There are basically no problems in the workshop. After all, the suppression of this technology is too great.

For this kind of magical Middle Ages, there were almost no methods of making steel. Lu En felt like laughing when he saw their rumored methods of making steel. For example, there was a way to bury wrought iron in the ground and dig it out after many years.

The iron will corrode, leaving only the steel...

The person who invented this method is really a genius. If he buries his head in the ground and digs it up after many years, all the excess parts will be corroded away, leaving only the wisdom.

There is also the extremely inefficient so-called steelmaking, which involves repeatedly beating the wrought iron to get out the slag and knocking out impurities such as silicon. It is time-consuming and labor-intensive, and the quality of the finished product is still very poor. It needs to be done by professionals.

The masters came up for secondary refining, but no matter which method they used, the yield was very low.

Because after Lu En's observation, he discovered that people in the Star Maple Kingdom did not even have a real method of making steel, not even basic iron casting technology. The method that continues to this day has always been to smelt iron using the block smelting method.

This may not be easy to understand, but in fact the furnace temperature here is very low, and it cannot even reach the melting point of iron. So we have to add charcoal and coal to perform a redox reaction to reduce the iron oxides in the iron ore to iron.

There are a lot of impurities, and the resulting thing is called sponge iron. It requires manpower to repeatedly forge dozens or hundreds of times to get wrought iron. Moreover, this kind of wrought iron is very soft, and a skilled craftsman can only make it in a week.

For two hundred kilograms of iron, the efficiency of professionals is much higher, even higher than that of blast furnaces. However, the number of professionals is rare after all, so in many cases wrought iron is used for carburization, forming a layer of steel on the surface, which is used by grassroots soldiers.

armor.

Under such circumstances, it is extremely scary for the earthen blast furnace provided by Luen to continuously produce low-quality steel. Although it seems to be inferior to Luen and the yield is not high, it is far superior to any other workshop in Larante.

The quality and quantity are also overwhelming.

But no one in Lalante knew this. The affairs of the workshop were kept well hidden, and it was impossible for the monster hybrids to reveal it, because no human beings were willing to listen to the monsters saying irrelevant things.

Lu En did not show up in front of the workshop. He just quietly watched the normal operation of the workshop from a distance. Bai was teaching Nana how to keep accounts. Everything seemed orderly.

This is all thanks to Bai, because she became a professional and her skill is "Coordination 1".

During this period of more than a month, Bai fully demonstrated her talent. Relying only on Lu En's occasional teachings and self-study, coupled with nearly two months of practice, and the accumulation during Bao's inquiry period, she really had the talent.

ability to manage this camp.

Lu En left her a copy of "On Practice" and "Analysis of Social Classes", which were written purely by hand. After that, she never showed up in this place again.

This place is already a member of Larante's business circle. Naturally, Lucian, a public enemy, cannot appear here openly. This is good for both parties. It doesn't matter if he appears, because no one will be monitoring here, and the steel will be directly supplied by Hui.

The steel that the Hall of Light sends to major workshops is processed by craftsmen. Everyone does not know the source of the steel and thinks it is the steel stored by the Hall of Light itself.

The person who is responsible for handling all this behind the scenes is Urathil. She does everything without leakage. If she leaks a little, Livia will teach her how to do it.

Looking at all this, Lu En always sighed.

"I'll go get Nana and Coral." Carla offered.

"No, let's go to the Blue River to look for corals. If Nana is there, let her play here, she's a kid." Lu En turned around and left directly. This camp is Lalante's fire. He can't keep it.

Waiting for the fire to slowly ignite nearby, what he needs is to sow the next fire in time.

Avoiding everyone's sight, Lu En clapped his hands as he walked to the edge of the Blue River.

The gentle water flow in spring suddenly accelerated, and in less than a minute, a group of transparent slime emerged from it.

A shallow water essence, she calls herself Coral.

"Have you been to my dungeon? How did it feel?" Lu En squatted down and asked with a smile.

This shallow water spirit was rescued a month ago. Since then, she has been traveling to and from Lu En's underground city in the forest, with the main purpose of transporting various materials in the water.

After all, half of Lu En's underground city is submerged in water, and it happens to be connected to the Blue River. For this shallow water spirit, transporting goods through the river water is as easy as moving your fingers, and it takes no effort at all.

, she is a level 4 monster, and her skill is Water Spirit 4, which allows her to control water flow and breathe in water. This is a natural skill, a skill she is born with, and cannot be upgraded. It is what she looks like when she is born.

These are also two general classifications of skills. One is acquired skills that can be upgraded through diligence, which is the case for most professionals. The other is innate skills, which are generally fixed and cannot be improved no matter how hard they train.

, but the advantage is that humans also have innate skills from birth. For example, in the human world, there is a great mage of the same level as Lu En during his heyday, a level 9 mage named Grand Master Daedalus. This human being is born with innate skills.

"Smart 6" heard that he learned to speak before he started nursing, and started studying runes before he could even walk.

With the skill Water Spirit 4, the water flow in the upper and lower reaches of the Blue River about 400 meters is the same as her body. Lu En arranged for her to transport supplies back and forth. In the past month, the dungeon has almost been repaired.

, just waiting for Lu En to take the people back.

Unfortunately, there was no one he could take back, so Lu En's next plan was to go to Coral's hometown.

"I've seen it... Lord Demon King, you are indeed very different from the Lord of the Four Seas Abyss. The rumors about you are actually true!" Coral replied happily and respectfully.

This month, she understood that there was a huge difference between the devil in front of her and the high-level monster who sold her. The other party really wanted to save these monsters who had no ability to protect themselves, and the other party did save them.

herself, so she is willing to stay here, just like the monster named Tailin, or like Nana, doing things for the other party, even if the other party has never asked for it.

After all, this was her own initiative.

"I'm glad you understand, but do you know why I want to keep you by my side?" Lu En squatted down and said to the translucent girl in the water.

"I don't know, but no matter what the reason is, I will be very happy." Shui Jing replied immediately.

"I hope you can take me to the seaside. The Blue River can lead directly to the sea. I don't have enough manpower on hand, but I think that the Lord of the Four Seas Abyss in your mouth must be there." Lu En stated his purpose.

He was leaving La Lante and going to sea.
