At this time, Gao Huan and everyone inspected the iron plant together.

Song Yingsheng, on the side, introduced: "Boye, the location of this iron plant is quite convenient. The iron ore is pulled down from Mangshan. Carboniferous is a little troublesome. You need to take land from Ruzhou to Yichuan, then load the ship to Yishui River, and transport it to Yanshi. Now the production of iron plant is restricted, mainly because the carboniferous roots are not raised."

Gao Huan nodded, "There is no charcoal for a hundred miles! The transportation from Ruzhou is indeed too far away. I will think of a solution for this matter."

"That's great!" Song Yingsheng hurriedly said.

Gao Huan had no choice but to find out if there were any coal mines nearby.

The group continued to walk and saw a large group of miners washing the mine sand by the Luoshui River.

Song Yingsheng was the prefect of Guangzhou, and the smelting industry in Guangzhou, Foshan and Dongguan was extremely developed. It not only could make bird guns and cannons for pirates at sea, but also made iron pots, but also sold all over the world.

"Brother, after washing this mine sand, it can increase the iron production rate and save carbon! "Song Yingsheng explained: "After adding this process, there is less slag, and the iron production is 30% more than before!"

Gao Huan originally just wanted to find Song Yingxing, but Song Yingsheng was just by the way.

Now it seems that I have found a treasure. After his management, the efficiency and technology of this iron factory have indeed improved a lot.

Now that he can build an extra cannon with a few thousand kilograms of iron.

Gao Huan nodded with satisfaction, "This is all the credit of Mr. Song!"

Gao Huan looked at the coal piled up in the distance and couldn't help but ask, "Don't you need to wash this charcoal?"

Song Yingsheng said: "Report to Bo Ye. The quality of carbide is related to the furnace temperature. Carbide must not only be washed, but also selected and divided into grades. However, in order to reduce costs, it has been cleaned in Yichuan before Yanshi."

In order to facilitate water withdrawal, the iron plant was built along Luoshui.

At this time, everyone came to a row of iron smelting furnaces. Each of these furnaces was ten feet tall and in the shape of a barrel. There was a blower next to them. The craftsmen were shirtless and pushed and pulled rhythmically to deliver air to the iron smelting furnace.

At this time, Song Yingxing, who was standing aside, spoke, "The iron plant is close to Luoshui and has water power available. Why does it take manpower? Isn't it laborious or time-consuming?"

Song Yingsheng gave Song Yingxing a blank look and said coldly: "These iron smelting furnaces are all left behind by the past and have not been built by me."

Gao Huan only recently learned that the two brothers Song Yingsheng and Song Yingxing have always been a little disagreement.

Both of them were over fifty years old, but when they met, they didn't deal with each other, like enemies.

Gao Huan didn't know the reason, and the two of them were unwilling to say it, so it was difficult for Gao Huan to help them resolve it.

Gao Huan hurriedly said: "This is indeed the previous iron smelting furnace, but the newly built iron smelting furnace can be used to blow the air in the future!"

Gao Huan brought Song Yingxing here this time, in fact, it was at the invitation of Song Yingsheng to help the iron plant, start and modify the technology, improve the production of the iron plant.

Song Yingsheng continued to introduce: "This iron smelting furnace can refine three thousand kilograms of ore sand at a time, and one furnace can produce about two hundred kilograms of pig iron."

At this time, there was a furnace open beside Gao Huan, and red molten iron flowed into the square pond along the diversion stone trough.

"Brother! The iron flowing out is pig iron, which can be used to cast various agricultural tools." Song Yingsheng continued to introduce.

Song Yingxing retorted: "This kind of pig iron is of poor quality and is not valuable. People's earth kilns can be produced."

After hearing his words, Song Yingsheng said angrily, "Without cast iron, how can we get ripe iron!"

Song Yingxing pointed to the craftsman who was frying iron and repeatedly beat him, "You can't practice much in a year if you practice iron like this, how can you go to the armour workshop forging guns and cannons!"

Gao Huan hurriedly called out, resolved the embarrassment, and asked, "Mr. Chang Geng, what are the ways to improve efficiency?"

Song Yingxing said: "Use hydraulic power! No matter how strong a craftsman is, he will be bored if he has hundreds of punches. The officials can improve the hydraulic forging machine made by the Armory Academy, manufacture a variety of equipment for the iron plant, perform hydraulic blasting and hydraulic forging, and improve the efficiency of the iron plant!"

Gao Huan was established very early, the Weapons and Equipment Research Institute, which is the Jiulongzhai Arsenal. However, because the craftsmen inside were limited in their skills, they had been established for a long time, but they did not make much work.

After Song Yingxing came to Luoyang, Gao Huan handed over the Weapon Academy to him, who was specifically responsible for improving weapons and equipment.

Gao Huan couldn't help but nod. If hydraulic power is used to produce, it will undoubtedly free more craftsmen, and the machine will not be exhausted and can operate day and night, which will definitely improve efficiency.

In this way, weapons that specifically restrained the heavy armor of the Qing army would have enough fine iron to produce.

...

Outside the pass, Shenyang City.

When Gao Huan was busy producing weapons, equiping the army, and responding to the large-scale entry of the Qing army into the pass.

After returning to Shenyang, Abatai was presenting the meeting of the Prince and Ministers of the Political Consultative Conference, so that the Qing nobles could judge the situation within the pass and make their own decisions.

At this time, in the hall, Dai Shan, Jirgalang, Dorgon and other princes were sitting on it, and a group of Beile, Beizi stood on both sides of the hall with a serious expression.

Abatai stood in the middle and explained the battle in Xingyang. "When I saw Gao Huan come out of the camp to attack the artillery formation, I snapped and led my troops to fight. Soon! I cut off Gao Huan's troops, but Gao Huan was not moral and made a sudden attack. I was careless and had no defense. He kicked the camp!"

Dai Shan asked after hearing this, "So, Gao Huan is better than you by using a strategy!"

Abatai blushed, "It can be said that! If it were a real dignified formation and fighting in the wild, Gao Huan would definitely not be the opponent of my Qing warriors!"

Jirgalang frowned, "If Gao Huan had made plans, the losses would not be worth ten thousand, right?"

Abatai's cheeks twitched and admitted, "Although my Qing warriors are better than Gao Huan's Yuzhou soldiers, Gao Huan's Yuzhou soldiers have a strong fighting will. They seem to be deliberately targeting my Qing soldiers and equipped with many blunt weapons. If you have to talk more, I think they are not inferior to Guanning Army!"

The Eight Banners nobles present were surprised when they heard this and immediately discussed it.

At this time, Boluo spoke: "There are no heavy infantry and heavy cavalry in the Central Plains, and there is no use of blunt weapons at all. Gao Huan is equipped with a large number of blunt weapons, as if he knows that we are going to enter the subway and attack Henan."

This incident made Abatai and Boluo very confused, and once suspected that there was a traitor within the Qing Dynasty.

After hearing the two of them, Dorgon couldn't help frowning, turned his head and asked Dai Shan and the others, "King Li, what do you think of King Zheng? Will this Gao Huan affect our plan to enter the pass?"

Dai Shan had a calm face, "If the soldiers in Yuzhou are not weaker than Guanning, then they will be my confidant in the Qing Dynasty."
