Send Black Mamba Snake, Ouyang Shuo returns to Marquis Residence.

Returning from Capital, Song Jia has returned to East Hedge Sword School, the huge Marquis Residence, empty.

However, Bing'er has been out of school, and the little girl has been well-behaved for half a year before finally being able to let go. At this time, I do n’t know where I took Little Black and Little White.

Little girl has an idea now and will not stick to his elder brother all day.

After drinking a little, Ouyang Shuo was dizzy, so I went back to the study and took a rest.

In the afternoon, Ouyang Shuo took two Personal Guard to No. 7 Research Institute.

Seeing that the end of the year, Ouyang Shuo also wanted to know what the results of No. 7 Research Institute had been in the past six months. There was basically no intervention in Ouyang Shuo for the daily work of Research Institute.

No. 7 Research Institute, located in the Eastern District, is a stone-made small building. The architectural style is similar to the adjacent Alchemy Workshop. There is a large open space behind Research Institute for various tests.

Sun Xiaoyue's grandpa Elderly Sun spends most of his time in North Sea Shipyard. Research Institute is usually mainly composed of Alchemist Magnus and hot weapons great master Liu Mo preside over. The current main attack direction is steelmaking technology.

The work of Research Institute obviously made Magnus very excited. When meeting Ouyang Shuo, he said enthusiastically: "Master, Oh ~ ~ Lord, welcome, welcome!" Then he would come forward and hug Ouyang Shuo.

Following the Personal Guard behind Ouyang Shuo, immediately step forward, press the knife with his left hand, and put on a defensive posture.

Magnus sees this and smiles. The Ouyang Shuo at this time is not the original Little Lord.

"Is Liu Mo in?" Ouyang Shuo hasn't seen this worship Big Bro for a long time.

In the end, Magnus is a Westerner with a cheerful personality and the embarrassing situation of the other person. He just smiled, and said with a smile, "Liu is at the test site, testing the steelmaking technology just researched."

"Oh? Has steelmaking technology already taken shape?" Ouyang Shuo was overjoyed.

"Of course!" Magnus is a little proud.

"Let's go and see!" Ouyang Shuo can't wait.

Ancient China steelmaking technology, started in Spring and Autumn Warring States period, mainly has two methods of carburizing and decarburizing. With the increase in demand for steel products, neither the wrought iron smelting method nor pig iron decarburization steelmaking can meet the requirements. In the later stage of Western Han, the technology of "steel frying" appeared. The invention of the technology of stir-fry steel made the 100steelmaking technology enter a mature stage.

Artisan heats the fine iron forging 100 more than one time, one forging one weighs one light, until the weight is not reduced, that is, one hundred steelmaking. The Wei and Jin period was the heyday of steelmaking technology.

During the Northern and Southern Dynasties, the steelmaking technology has achieved a breakthrough across the ages, inventing the "irrigated steel" smelting method.

irrigation method of steel uses both pig iron and wrought iron at the same time. It takes advantage of the high carbon content of pig iron, lower melting point than wrought iron, and dissolves first. The two raw materials are mixed together and heated, and the dissolved pig iron is used as carburizing. Agent, poured into the gap of loose wrought iron, so that the carbon content of wrought iron is increased to become steel.

In the Sui-Tang period, irrigation method of steel was vigorously promoted and applied.

Song-Ming Period, with the development of cold forging technology and quenching technology, the types and properties of steel have been further improved. The steelmaking technology at that time was at the leading level in the world.

Unfortunately, after Qing Dynasty, because of Qing Dynasty's closure of the country, steelmaking technology of China has been stagnant, no breakthrough was achieved, and it was finally overtaken by Western countries, ushered in a period of humiliating History.

What No. 7 Research Institute restored was irrigation method of steel in the Sui-Tang period.

As Expert on Hot Weapons, Liu Mo knows the Ancient China steelmaking technology well. In addition, there are books such as "Dream Pool Essays" and "Exploitation of the Works of Nature" in the Tibet that record various steelmaking technologies.

Even so, restoring irrigation method of steel has been bumpy.

No. 7 Research Institute took half a year, and after repeated trials and tests, it finally formed the irrigation method of steel research. Otherwise, how can Technical Manual be precious? If there is a ready-made volume "irrigation method of steel Technical Manual", why do you have to experiment so hard to directly grasp the detailed proportions and conditions.

In the backyard, there is a huge ironmaking furnace, and there is a complete set of supporting facilities.

Liu Mo is busy in front of the ironmaking furnace and instructs Artisan to control the heat.

When I saw Ouyang Shuo, the Artisan saluted one after another: "Meet Ruling Marquis!"

Ouyang Shuo waved his hand to signal their continued work.

"Big Bro Liu!" Ouyang Shuo called Liu Mo.

As territory grows stronger, Liu Mo and these player(s)s, their attitude towards Ouyang Shuo's is also imperceptibly and slowly changing. Although they don't respect the Ouyang Shuo like the original residents, they are not at least as casual as they started.

Liu Mo is just a technology madman, don't care about these red tapes.

The two are just chatting in the backyard.

According to Liu Mo, restoring irrigation method of steel is only the first step.

Next step, Liu Mo is going to make a further breakthrough on Foundation of irrigation method of steel, so that steelmaking technology of territory can catch up with the level of Western countries.

One of them is the choice of fuel.

Ancient iron-making used charcoal as fuel, and did not use phosphorus-containing solvents, so the ancient pig iron contained a low amount of phosphorus. The cast-iron furnaces used in ancient times were not high enough to melt the iron sufficiently.

Liu Mo means coal instead of charcoal.

Ouyang Shuo frowned, looking a little embarrassed. China Region coal mines are mainly distributed in Mongolia and Hedong provinces. Lianzhou Basin does not have coal mines at all.

Feng Qiuhuang's Falling Phoenix District is located on the Hedong boundary.

It seems that to find time to discuss with Feng Qiuhuang, Ouyang Shuo within heart thought.

"The coal thing, I will find a way to solve it, Big Bro Liu need not worry!"

"Okay!" Liu Mo is in full shape.

In view of the fact that steelmaking technology has taken shape, Ouyang Shuo immediately decided to build a Large-scale Steel Mill in Shanhai City to meet the demand of territory for steel.

The site selection and construction of Steel Mill, Ouyang Shuo is all entrusted to Liu Mo.

Back to Marquis Residence, Ouyang Shuo immediately wrote to Feng Qiuhuang to discuss the coal trade between territory.

Ouyang Shuo's means that Four Seas Depository injected capital into a certain Large-scale coal mine in Falling Phoenix District. The coal mine was mined and it was used to supply the coal demand of Shanhai City.

Of course, the premise is to find a book "Coal Mine Extraction Technical Manual", otherwise everything is in vain.

coal is called Blackstone at Ancient China, and it is not widely used. Finding such a Technical Manual can take some time.

Ouyang Shuo simply commissioned And Spring Remembers Chamber of Commerce and Cui Chamber of Commerce, asking them to help search.

Mulan District, Lord Residence.

After New Year's Day, the weather in Lianzhou Basin started to turn cold and bustling.

Looking at the scenery of bleak and desolate outside the window, Mulan Yue stunned. After returning from Capital, Mulan Yue has been thinking hard, and he is often dazed outside the window.

I don't know. I thought the little girl was pregnant.

Li Feixue stands behind Mulan Yue, turning a dagger boringly in his hand. The dagger was very delicate. It was bought by Mulan Yue when she was in Capital.

After the battle of Zhennan Pass, Li Feixue joins Mulan District. At first, the death of his father made Li Feixue very depressed for a period of time. It was Mulan Yue's careful care. Seeing her like a younger sister, she let her out of the shadows and start a new Livelihood, so she was very dependent on Mulan Yue.

With her insistence, she will be Mulan Yue's personal Guard.

Don't look at Li Feixue is just a little girl. A Martial Arts can't be underestimated. With her personal protection, the safety of Mulan Yue is guaranteed. Mu Guiying now stays at Army Camp most of the time.

I never thought that without the company of Mu Guiying, Mulan Yue would become a lot more independent, a little less dependent, a little stronger. Her light gradually began to shine in territory.

At first, the immature little girl was handling the territory transaction, and she was already pretty.

Operating a county is really a big challenge for Mulan Yue.

Fortunately, Mulan Yue has an innate Talent on the development of Territory Economy, coupled with her dissatisfied personality, she stumbles all the way, but it makes Mulan District's business sound and colorful.

Otherwise, previous life Mulan Yue will not be one of the three giants of Lianzhou Basin. In the fight against Evil Wolf, Tyrant Blade and Dawn Wind Ruins Moon, they will not fall in the slightest.

Mulan Yue has the advantage of being good at drawing lessons.

Inspired by Shanhai City's vigorous development of characteristic industries, Mulan Yue promoted rapeseed planting in territory, and set its sights on the oil in "Chaimi Oil Salt Soy Vinegar Tea".

Sure enough, rapeseed oil is very popular and brings a huge return to Mulan District.

Not only that, Mulan Yue also introduced Shanhai City's colored silkworm breeding industry.

Mulan District's Economy strength is also ranked in Shanhai Alliance member.

In terms of government affairs, Mulan Yue copied the architecture of Shanhai City.

Handling government affairs is her weakness.

The npc brushed out by System, although under the influence of Gaia, will not be as old-fashioned as the ancients, but there are some doubts about the little girl Lord, Mulan Yue.

This is why it's hard for women to get ahead in Lord.

Mulan Yue, like not like Feng Qiuhuang and White Flower, is surrounded by a group of people and lacks sufficient experience. The little girl can only follow the steps in handling government affairs.

Most of the government affairs are left to her subordinates.

"Feixue, go and call Elder Sister Mu." Mulan Yue turned back and said, turning his head.

"Ah!" Li Feixue responded fragilely, put away the dagger, trot out, a pair of small braids dangling, a little more playful.

A short while later, Mu Guiying rushed over.

"elder sister, I think, it's time to turn territory of Mulan District merge into Elder Brother No Clothes." Mulan Yue spoke amazingly, this is also issue that she has been thinking, obviously now has reached a conclusion.

Mu Guiying is silent, she knows, don't look at Mulan Yue's softness and innocence on the surface. In fact, the little girl can have an idea. Once she makes up her mind, it will be difficult to change.

"Okay, let's go to Shanhai City."

"elder sister, do you agree?" Mulan Yue said happily.

"Of course I support you!" Mu Guiying said with relief, watching Mulan Yue's growth is also a comfort to her. (.)
