In the past six months, the shipping capacity of the Fanyang Chamber of Commerce in charge of Yang Kongcian has increased by nearly 100,000 stones, and the increase in the transportation capacity of each stone represents a huge increase in profits.

In addition, it also provided a large number of warships for Wang Junlin's sailors, and the Yanchang Shipyard in Fanyang County invested more than 500,000 taels of silver in Wang Junlin's personal property in the past half a year, and the total scale of shipbuilding has now exceeded 300,000 stones.

In particular, steel fittings gradually became popular, and in addition to the large-scale use of iron nail riveting, the Yanchang shipyard even began to use large iron castings.

In Wang Junlin's impression, an iron sailing ship with the same load was heavier than a wooden sailing ship. In fact, it has been calculated that a steel sailing ship of the same load is even two to three percent lighter than a wooden sailing ship.

It is completely necessary to build a steel-hulled sailing ship, and a thousand-stone ship needs to use up 100,000 catties of good iron, which is not something that today's Wang Junlin can afford. After all, although Fanyang County is up to him, it is still under the rule of the Great Sui, and in order not to make Yang Guang jealous, he tries not to contaminate the resources of Fanyang County as much as possible, and all the taxes are handed over to the imperial court.

What's more, even with the existence of Nie Xiaoyu, the low-cost steel plate manufacturing technology should be matured, and it is difficult to really grow up without more than ten years of accumulation of technology, but the use of iron castings to manufacture key components of sea ships can make the ship's structural strength higher, the technology is not complicated, and the cost can be tolerated.

However, with the existence of Nie Xiaoyu, the first rudimentary iron-making blast furnace was also built in the newly built iron and steel plant in the salt field three months ago, which increased the steel-making efficiency by more than five times, according to the calculation, after the construction of five more such iron-making blast furnaces, Wang Junlin's refined iron output in the salt field will increase to 400,000 catties per year.

Such an output, in later generations, is only a year's output of a small private iron workshop, but in today's Great Sui, it is already one-third of the output of the entire Great Sui.

However, after the budget, every time such an iron-making blast furnace is built, at least 100,000 taels of silver need to be invested, and the cost is not low.

……

……

In the third month of Wang Junlin's return to Fanyang County, that is, the sixth year of the Great Cause, on the sixth day of the first month, Emperor Yang Guang finally couldn't bear it anymore, and despite the strong opposition of some ministers, he officially issued an edict announcing a crusade against Goguryeo.

As for the specific battle plan, Yang Guangdu did it single-handedly, and he didn't need the military department to intervene, and he didn't even call the generals and ministers to discuss.

Yang Guang spent more than a year looking at the map in the imperial study, and finally decided that the conquest of Goguryeo would require 1.5 million people, including 600,000 soldiers, about 900,000 auxiliary soldiers, and more than 3 million laborers to transport grain and grass.

According to Yang Guang's plan, he divided his troops into three ways to conquer Goguryeo, and the land was divided into two wings, left and right, twelve armies on each wing, the first army on the left took the square road, and the second army took the Changcen road, which has been tiled on the map to the Lelang Road of the Twelfth Army, and the same is true for the Twelfth Army on the right.

In addition, because Wang Junlin had already written that he had occupied Goguryeo's Dami Island and Bailing Island, and Zhao Chen, the head of the Fanyang County Water Division, also wrote a book, saying that his 30,000 water divisions could be called elite.

In addition, Yang Guang has always trusted Wang Junlin, because Wang Junlin has never let him down, so he set up a waterway army with the water division of Fanyang County as the main division, and cooperated with the expedition against Goguryeo.

It's just that Zhao Chen was disappointed that Yang Guang actually ordered Wang Junlin to be the main and him as the auxiliary, although he was depressed, Zhao Chen secretly breathed a sigh of relief.

Although he went to the battlefield when he was young when he was young, he was really worried about the military exploits of the first army in command compared with Wang Junlin's great military exploits, and to be honest, he was really a little worried about letting him unify the army alone to fight.

Now although Wang Junlin is the main general, but in his opinion, the 30,000 sailors are under his control, how can he have less of his own military achievements, and Wang Junlin has to act according to his own face, but if he loses the battle, he can completely shirk the responsibility of Wang Junlin.

……

……

Fanyang County is too guarded.

Wang Junlin looked at the map of Liaodong and Goguryeo, with a helpless and wry smile.

According to the map drawn by Nie Xiaoyu himself, he couldn't find the twenty-four roads that Yang Guang said to go, and the west side of Ma Gongshui (Yalu River) was okay to say, somewhat flat, but after passing Ma Gongshui, from the map, he saw that the mountains over there were next to each other, and there were no more than three roads that could be walked together.

"Yang Guang also personally led troops to fight when he was young, and he didn't want to stay in the palace now, but he made this kind of low-level mistake of talking on paper." Wang Junlin looked sneered and helpless, wondering if he would send a fast horse to send this map to Yang Guang now.

But when he thought that Yang Guang loved face the most in history, had the strongest vanity in history, and was the best emperor in history, he would now send the map and object to Yang Guang's battle plan, or even reject it entirely, which would only bring death to himself.

The reasons are ridiculous, but they're also simple.

First of all, Yang Guang has officially issued an edict, this battle plan has been handed down to officials and generals in all aspects, not to mention the issue of changing the imperial order, His Majesty the Great Emperor, will never allow such a shameful thing to happen to him.

Secondly, this mistake is too low-level, so low-level that Yang Guang's character will give birth to 100% annoyance and anger, ordinary people will only scold people when they are annoyed and angry, and beat people at most, but Yang Guang is followed by a monstrous murderous machine, this is not nonsense, take a look at the past few years to dissuade or persuade Yang Guang in person, the ministers who are fierce and not tactful enough to speak are miserable

The consequences will be known.

According to the information sent by Xu Jingzong and Shen Guang, Wang Junlin knew that eleven courtiers had been killed with a cane for advising Yang Guang, and nine others had been put to prison, and more than 20 people had been demoted to the rank of knight.

As a result, now in the Great Sui Imperial Court, no one dares to tell the truth, the so-called "loyal words against the ear, good medicine bitter mouth", Yang Guang obviously dislikes the most people who listen to the words against the ear and take the medicine of the bitter mouth, so it is basically impossible for someone to give him advice and give him good medicine.

Throughout ancient and modern times, no matter how strong the ruler's ability is, when he begins to act arbitrarily, it means that mistakes will occur one after another, and the development of the country will gradually take a detour, and then fall apart, because there is no perfect person in this world, and history has long proved that "working together" is the king.
