Although the three Koreas are nominally divided into South Korea, Central Korea and North Korea, in fact, the three Koreas are only divided into two parts, of which South Korea is divided separately by Li Su, and all the local aboriginal people are moved out, and only Han people are allowed to live. Of course, there are still some nobles in South Korea who used to be Baekje and Silla, but these nobles have now lost all their privileges and do not have any mass base, and even when they get along with the Han Chinese, they will receive strange eyes.

In addition, it is worth mentioning that the number of these former Baekje and Silla nobles is very small, only two or three thousand together, and they are scattered all over South Korea, and at the same time, these former nobles have worked hard to integrate into the Han nationality in order to eliminate the strange eyes of the Han people, plus they have all received Chinese education before, so in a few years, maybe even they will forget their original origins.

South Korea only allows Han people to migrate, but this ensures local security, coupled with Li Su's series of policy preferences for South Korea, so the Han people in South Korea have increased greatly, most of them are from Dengzhou and Hebei, Henan two provinces moved over, now the total population has reached 300,000, in the territory controlled by Li Su, the Han population is second only to Taiwan.

The counterpart to South Korea is North Korea and Central Korea, which are inhabited by a large number of former Baekje and Silla people, and the population there has reached 4 million, of which two-thirds are Silla, and the rest are all Baekje. In fact, the Silla people and the Baekje people are both the same ancestor, and there were originally some ethnic minorities in both countries, but after the destruction of the two countries, they were generally called Silla and Baekje.

Li Zhi's first stop. It was the closest South Korean state to Dengju, when Li Zhi's fleet entered the port not far from Sihyeon. Lu Hong, who had already received Li Su's order, stood on the dock and welcomed Li Zhi into Siyu City with a smile on his face.

Although Li Zhi did not know Lu Hong. But I have heard his name, and I know that this person is a rare capable minister, who is highly valued under the sixth brother Li Su, and his status is equal to that of Wang An, and now he is in charge of the government affairs of Sanhan and the Wa Kingdom, and the sixth brother can send him to meet him, and Li Zhi also guessed some of the intentions of this.

After resting for one night in the royal palace in Si Xian City, Li Zhi originally wanted to go to Lu Hong and ask him some questions. However, Cai'er was enthusiastic and pulled them to visit the Si Yu Palace, the first half of this palace is nothing special, but the back garden is a very windy scenic spot, but unfortunately it is not March, otherwise Li Zhi and his son can enjoy the beautiful scenery of the cherry blossom garden.

The back garden was originally built by the king of Baekje, but after it was occupied by Li Su, he invited many skilled craftsmen from the Tang Dynasty to carry out a new round of renovation here, making the back garden combine the artistic characteristics of Baekje and the Tang Dynasty. It has become more charming, and even Li Zhi and his son, who are used to seeing various gardens in Chang'an, are full of praise when they see it, and the son is even more noisy and must live here for a while in the future. Not this time, though.

After visiting the palace, Li Zhi had the opportunity to find Lu Hong, first, he wanted to ask the other party to arrange his itinerary in Samhanzhou. Second, there are some questions I want to ask. However, Lu Hong had already received Li Su's order and had already arranged the matter at hand. So he was ready to accompany Li Zhi throughout the whole process, which of course made Li Zhi very happy.

In the afternoon of the same day. Lu Hong accompanied Li Zhen to the south of Si Hyun City, a new industrial city called Steel City, from the name of this city, it can be seen that the city's main industry is smelting steel, in fact, the reason why South Korea drove out all the original Baekje people, in order to establish a steel base here to meet Li Su's demand for steel.

When Li Zhi rode a horse and just saw the steel city, he found that there were many huge furnaces towering in the city, which were important equipment for ironmaking, and at the same time, puffs of black smoke came out from these furnaces, dyeing the entire sky over the steel city gray. And when Li Zhi entered the city, his nose was filled with the smell of steel and coke, which smelled very pungent.

This time, the son and Cai'er did not come with Li Zhi, firstly, because they had been playing in Dengzhou for a few days and had been taking a boat, so they felt a little tired and now stayed in the palace to rest, and secondly, Li Zhi came to see the steel mill this time, which was really not interesting for girls, so they didn't follow.

After entering the steel city, Li Zhi found that the whole steel city was actually a huge steel plant, the streets were lined with rows and rows of production plants, and the whole city except for the garrison of 2,000 people, there were no residents at all, all the workers working here all lived in a valley five miles outside the city, where the forest was dense, the environment was beautiful, and the unhealthy atmosphere emitted by the steel city could be kept away, and a two-way railway was built from the valley to the steel city, which was convenient for workers to enter and exit the steel city.

Steel City is one of the most important steel producing areas in South Korea, with an annual output of 2,000 tons, and there are several other smaller steel bases in South Korea, plus the steel production in Taiwan, Li Su can get 5,000 tons of steel from these steel mills every year, this number is not worth mentioning in the eyes of later generations, but for the seventh century AD, it is already very remarkable, you must know that before Li Su crossed, with such a huge territory of the Tang Dynasty, the annual steel output was only a few thousand tons, and later Li Su used coke to make ironCoupled with the reform of some smelting technologies, Datang's annual steel output is only about 10,000 tons.

As the crown prince, Li Zhi is naturally very clear about the steel output of Datang, so when he knew that the annual output of the steel city in front of him had reached one-fifth of the entire Datang, he was naturally stunned, especially when he knew that there were only more than 10,000 workers in the steel city, which made him even more unbelievable, but after he visited the steel city, he finally dispelled the doubts in his heart.

This is mainly because Li Zhi found that in the steel production workshop of the steel city, a large number of steam engines have been used to replace manpower, such as the use of a gravel conveyor belt, which saves a lot of labor, and there are also gravel crushing, blasting, etc., all of which are replaced by steam engines.

"Bang! "In the most central location of the steel city, here is the production workshop of the production of steel, compared with the annual output of two thousand tons of iron, the steel output of the steel city is less than 100 tons, this is not that the steel city can not produce more steel, but compared with the expensive steel, the use of iron is still much more extensive, so the current steel output has been controlled by Li Su, enough every year, for the time being, do not seek to expand production.......

Li Zhi looked at the steel ingots transported from the conveyor belt in front of him, and then looked at the sweaty workers around him, wiping their sweat with towels from time to time, and couldn't help but feel a little emotional, he only knew the importance of steel to the country before, but it was the first time to see the production process of steel, and at the same time the first time to see these workers around him, almost everyone had burns on their arms, and even some workers had large burns on their faces, resulting in a very terrifying appearance. Luckily, I couldn't even find a single bone.

"Mr. Lu, since the work of smelting steel is so hard and dangerous, why don't you let the slaves do it, don't there be many slaves under the sixth brother who work in various places?" Li Zhi looked at the workers who were disfigured by the molten iron, and asked Lu Hong very puzzled. He knew that the sixth brother asked Lu Hong to accompany him, in fact, to answer some questions for him, and now Li Zhizai found that the workers in the entire steel city were Han, so he asked this question.

Seeing that Li Zhi could ask such a question, and he did not have the slightest arrogance towards himself, this made Lu Hong also nod secretly, thinking that he was worthy of being the younger brother of His Royal Highness King Qi, if this person ascended the throne as the emperor in the future, he would definitely be a generation of masters.

I saw Lu Hong smile slightly, and saluted Li Zhi and said: "Your Highness, your proposal is very good, but there is one point that is not well considered, that is, steel is the top priority for a country, and the same is true for steel production technology, if those slaves are used to replace the workers here, then it is inevitable that something will go wrong, in case the slaves here escape, then the steel smelting techniques that our Datang has worked hard to study will not all be cheaper than those aliens?" ”

Li Zhi suddenly had a sudden feeling of realization when he heard this, and blurted out at the moment: "I see, no wonder the sixth brother wants to move all the Baekje people in South Korea out, and he also forbids non-Han people to live, it turns out that it is to keep the smelting technology of steel!" ”

Seeing Li Zhi's reaction so quickly, Lu Hong also nodded a little proudly, this method was what he and Wang An thought of, only to see him continue: "Your Highness is wise, the people who moved here are indeed for secrecy, after all, these alien races are not credible, unless they are completely sinicized, South Korea will never let the people of other nationalities move in!" ”

However, when Lu Hong said this, he suddenly paused, then looked up at Li Zhi, and then spoke again: "In addition, it is not only necessary to keep secrets in terms of technology, but also to prevent these alien races in terms of the army, for example, in the hands of His Royal Highness, although there are also armies of Sanhan, Wa Kingdom, Linyi and other countries, but these armies cannot be compared with the Han army in terms of weapons and equipment and training, as for the firearms troops, only Han soldiers can participate!" ”

Li Zhi didn't feel anything at first, he just felt that what Lu Hong said was very reasonable, but then he suddenly came to his senses: Lu Hong's words didn't seem to be just talking about the sixth brother, right? (To be continued......)
