When the frame of the hearth was basically set up, Su Chengyu remembered that there was only manpower blast equipment in the iron yard when he saw the air outlet.

Fortunately, it would take some time for the hearth to be completed, so he called Chanyi and instructed her to contact the merchants who had supply cooperation with the iron yard in the past to buy a set of animal-powered blast equipment. In addition, she was also asked to buy more coke reserves, and if the supply of coke was insufficient, she could even consider building her own coke oven.

The thermal efficiency of crucible steelmaking is less than 30%, and the fuel consumption is considerable.

By the time Su Chengyu returned to the barracks, it was almost dusk. He just felt that there were too many things to do lately, so he simply made a work schedule for himself.

At the top of the list are steelmaking-related matters. If there is no steel mill, there will be no silver, let alone training, and it is estimated that the troops will mutiniate in a few days.

Then there are the teaching materials related to military training, he has already compiled a small part on the way to Longnan, and this must be completed quickly, after all, the large army is about to arrive.

It is also necessary to draw up a guiding plan for the military's ideological work building as soon as possible, and the establishment of a soldier's sense of mission, honor, and responsibility is even more important than weaponry.

When it came to weapons and equipment, he remembered that Lu Ning and other craftsmen brought by Fujing were now helping on the construction site of the barracks, and they had been so busy that they hadn't taken care of them recently. It is too wasteful for these talents to let them do the work of ordinary blacksmiths and carpenters, so they can start trial production of medium-caliber flintlock pistols, and strive to start mass production as soon as possible.

He immediately thought of Serio again. When he first came to Longnan, he instructed the watchmaker to choose his own site to build a watch workshop, and he didn't hear back from him for several days. I'll have to ask tomorrow. After the workshop is built, a group of apprentices must be recruited, and the watch industry is the enlightenment teacher of industrial finishing, and these apprentices will be an important force in the Ming processing industry in the future. If Serio knew that the apprentices Su Chengyu planned for him to train were hundreds, he would definitely regret his promise to Su Chengyu.

In addition, there are many important things that have to wait for the will of Longwu's side, and Su Chengyu can't do these things by himself.

He reviewed his work schedule, asked the guards to wipe his face with a cool towel, picked up a bamboo pen, and began to continue compiling military training materials according to the modern military training subjects he remembered. I guess tonight will be another sleepless night.

The next day, Su Chengyu took Lu Ning and seven other firearms craftsmen to the "Su Ji" iron field together with their apprentices.

There are many ready-made wrought iron sheds, and Su Chengyu picked a place with better conditions and handed it over to Lu Ning and others. This is the first firearms workshop of "Su Kee".

He instructed the firearms craftsmen to tell Mr. Shen, who was in charge of the iron yard, that the tools they needed to prepare, which were actually Chanyi, and then began to resume the production of flintlock guns.

However, the gun pipe had to be remade, and the adaptability of the light gun gun used by the Ming army to fire three-coin guns and bullets was too low. Su Chengyu set the new fire gun to fire lead bullets of six to six to five cents, and used four to five coins of gunpowder.

Let Lu Ning and them try to make the pipe, and repeatedly told them to make the pipe wall thicker at the beginning to ensure that the bore is not blown up first, and then gradually reduce the weight when the process is mature.

Then he left Chanyi a thousand taels of silver, which must have cost a lot of money in the early stage of construction, and this thousand taels is estimated to be far from enough.

Construction is still underway on the hearth, and the refractory bricks have been basically laid and are being lit and burned. The inlet and outlet ducts and chimneys are still under construction, but they should be ready for use in a day.

The installation of the newly purchased animal power blower unit has already begun. A row of wooden shelves, connected to bellows more than half a person high, is driven by a set of levers by one or two donkeys dragging a turntable. This thing is not expensive, but the main cost of the two donkeys is ninety taels.

After Su Chengyu learned about the construction progress of the hearth, he rushed to the porcelain kiln non-stop.

The first crucible has been cooled and is standing in the courtyard.

However, when he looked closely, he couldn't help but be disappointed that there were many small cracks inside the crucible, especially at the bottom.

Although they are fine lines that can only be seen clearly in front of his eyes, Su Chengyu is very aware of the danger of these cracks under the high temperature of more than 1500 degrees.

He immediately ordered the cauldron blank to be burned for preparation, and repeatedly told him to slow down the temperature and prolong the cooling time. The craftsmen of the porcelain kiln are also experts, and as soon as Su Chengyu said that they knew what to do, they patted their chests to ensure that the next crucible would be burned.

After a busy day, when Su Chengyu's carriage drove to the gate of the barracks, he saw that the stone that was more than one person high had been moved to the center of the gate, and there were four vigorous characters engraved on it-Longwei New Army. It is the new army number given by Longwu in the secret decree.

The stone was unadorned, still maintaining its original and rustic style, coupled with the crimson words "Longwei New Army", and the four sword-wielding guards standing on both sides, a majestic and mighty aura came to the face.

The barracks of the New Army finally have a bit of a taste!

Shi Lin was anxiously walking back and forth at the gate of the camp, and when he saw Su Chengyu coming back, he hurriedly greeted him, "Master, someone from Tianxing Mansion is here!" I waited in the camp for most of the day. ”

Su Chengyu hurriedly walked towards his new barracks.

Along the way, Shi Lin reported to him about the recruitment.

In general, it did not go well, and less than 20 people were recruited in these five or six days. However, this was not what Su Chengyu expected.

The Ming Dynasty's guard system was extremely rigid, resulting in the number of deserters repeatedly breaking new highs. As a last resort, the imperial court could only stuff all the messy people into the army, mainly heavy prisoners. At that time, being a soldier was a thing that only porcupines and dogs did in people's hearts. The saying that "a good man should not be a soldier, and a good iron is not a nail" was a general consensus in the Ming Dynasty.

So as long as it's not really unbearable, no one wants to be a soldier. And those who are really difficult to live have long been recruited by Yang Tinglin and Yang Butang.

Su Chengyu was not very worried about this, and after the emperor replied to his secret performance, he had his own means to solve it.

Su Chengyu's new general camp has been built, and it is a two-room hut with a civil structure. As soon as he pushed the door in, a person who had been waiting inside jumped up from the chair, it was the middle-aged eunuch who had passed on the secret decree for Longwu last time, and it seemed that he should be the emperor's confidant.

The eunuch came over and said hurriedly: "Your Highness, you can count yourself back!" The Holy One has instructed our family to hand over the secret decree to you, and our family has been here since the morning......"

"There is Father-in-law." Su Chengyu took out a silver ingot and handed it over quietly. The people around Longwu can make friends with investment points.

The middle-aged eunuch smiled and put away the silver, and handed the secret decree of the wax seal to Su Chengyu, "Our family still has to return to the saint." After saying that, he left in a hurry.
