When Huang Yao came up with the box.

Yang Chengying, who couldn't see the real thing, was so excited that his hands trembled slightly.

After tungsten ore is refined, the drill bit produced is hard and wear-resistant. If you improve the machine tool again, you can increase the production speed and achieve preliminary precision machining.

In this way, epoch-making inventions such as the steam engine had the basis to be made.

"Dashuai, this is the black stone that Ma Santai encountered while hunting."

Huang Yao put the box on the table and opened the lid.

A black stone that Ma Santai said appeared.

Yang Chengying Huo Ran got up, picked up the stone and looked at it carefully in the firelight, it was really amazing.

This is indeed tungsten ore.

"Yang Shuai, is this kind of stone really as magical as you say?"

Song Yingxing approached and looked at it carefully.

"Of course. However, this thing is not easy to smelt. ”

Yang Chengying said: "This requires long-term experimentation and wastes a lot of manpower and material resources to practice it." ”

"Don't worry, I don't have anything else, I have patience."

Song Yingxing smiled faintly.

Several failures in the imperial examination made him die of this heart.

However, there is no endless road, and in his spare time, he reads the works of his predecessors, such as Mengxi Pen Tan and other works, or the works of Xu Shangshu of this generation, which makes him deeply interested.

With such an opportunity to realize himself, he naturally has to grasp it firmly.

"Good! I'll work with you for some time to come. ”

Yang Chengying said: "Let's put up the shelves first, and then proceed step by step. ”

"Of course it's fine." Song Yingxing asked, "It's just that the handsome man has a lot of opportunities, do you have this time?" ”

"I'm okay too. Whether the Tartars withdraw or not, I don't have to go to the front line in person, and wait for the matter here to be clear. ”

"Okay."

Song Yingxing nodded slightly, he didn't have a score in his heart, but now he was a lot more relieved.

Early the next morning, Yang Chengying and Song Yingxing arrived at Dagou in the northeast of Xiuyan City under the guidance of Ma Santai.

Checked the situation here and determined that it could be mined.

The first thing to solve is the road.

To get the mine from the mine here, you need a road.

Yang Chengying directly mobilized the local people and the soldiers guarding the fort to build a road for horse-drawn carriages to pass through at a high price.

Then there is a group of craftsmen composed of 17 people, including Wang Tianxiang, who built three smelting kilns with local materials.

They alone were not enough, and after identifying the tungsten mine, they recruited single craftsmen from the Ordnance Bureau and let them work in Xiuyan City.

In order to stabilize them, Yang Chengying did something against his will.

That is to let Shen Shikui buy people from the tooth shop and distribute them to these craftsmen through blind dates.

He felt uncomfortable, but the women didn't care.

Compared with the fate of being displaced and even possibly in the pot, they are more willing to live a stable life with the craftsmen.

There is enough food to eat every day, and the men in the family still have salaries, and no one dares to bully them.

I don't know how many times better than the previous days.

In order to reduce the pressure on materials, at the instigation of the men in the family, they also dig wild vegetables in groups.

The smelting of tungsten ore is complex and requires the application of chemical and physical knowledge.

So, while building, give them a lesson in person.

was in full swing when the news of Huang Taiji's withdrawal came.

"Dashuai, how did you get like this?"

The signal corps often sees Yang Chengying, and he is not used to it. Seeing Dashuai like this, he was a little distressed: "You are the heaven of Liaodong, don't practice yourself like this." ”

Doing hard work is inherently dirty and tiring. The conditions here are simple, Yang Chengying often has no time to change clothes, and there are still a few scratches on his clothes.

If you don't look closely, you think there are beggars in the castle.

There is no prestige of the general army of a town.

"If I have something to say, I still have to go to work if I have nothing to do."

Yang Chengying urged while rolling up the sleeve that had slipped to his arm.

"Oh, Marshal, the Tartars have withdrawn."

The signal soldier handed the letter to Yang Chengying: "General Zu wants to ask you what to do next." ”

"Withdraw the troops, and tell Zu Dashou in addition."

Yang Chengying said while reading the letter: "Our army urgently needs to rest, let him pay attention to the movements of the Tartars." Besides, tell Shang Kexi and reward him when I go back. ”

"Yes." The Signal Corps straightened his body.

"Anything else?" Yang Chengying asked.

"Not for now."

"Let's go down."

"Yes."

After the signal corps left, Yang Chengying continued to work again.

Industrial tungsten production has a very complex process, using tungsten oxide, hydrogen, etc. And to make these, you need the corresponding materials.

At the same time, subject to the times, it is necessary to simplify and use local materials.

This all posed a series of problems to Yang Chengying and Song Yingxing, making him have to devote his energy to the laboratory.

While devoting himself wholeheartedly to tungsten production, Houjin was also resting, preparing to invade Jizhen for the second time.

A mutiny that took place on the territory of Shandong is still going on.

The rebels burned and looted all the way, terrifying Yu Dacheng, the governor of Shandong.

This Yu Dacheng is the same Yu Dacheng who persuaded Yuan Chonghuan to write to He Kegang.

Yu Dacheng sent Shen Tingyu of the Chinese army to lead the army to encircle and suppress.

The soldiers led by Shen Tingyu are standard battalions, and he himself is also a fool.

went into battle to fight, and actually chose to sit in a sedan chair.

It was easily defeated by Liu Zeqing's army and captured a large number of soldiers.

"Haha...... There is really no one in this court. ”

Li Jiucheng sat on the sedan chair that Shen Tingyu had sat on, and laughed: "It's really stupid to send this kind of waste to fight." ”

"Don't be too happy, the next stop is Laizhou."

Liu Zeqing arrived on horseback and broke him a basin of cold water: "After so many years of operation, Laizhou and Dengzhou have strong cities and are not easy to capture. ”

"What are you afraid of?" Li Jiucheng got off the sedan chair, "As long as the Ming army in Liaodong does not move, this Shandong is our world." ”

"It's better to be like this."

Liu Zeqing sighed and said, "I only hope that God will bless you and let the Tartars drag the Liaodong Ming Army longer." ”

Li Jiucheng looked up at the sky and thought to himself, if God really had eyes, he would not let Inspector Yuan die so miserably. I won't let myself go hungry every day, and when I become a rebel, I have a full meal.

On the eighth day of November, several thousand rebels arrived at the city of Laizhou.

Zhu Wannian, the prefect of Laizhou, organized the defense of the military and civilians in the city on the one hand, and sent his staff to send wine and meat to the rebels.

After all, the rebels raised the banner of returning to Dengzhou to ask for food.

"It's exquisite!"

Facing these wine and meat, Liu Zeqing smiled and said, "Since Master Zhu is so interesting, I won't let him suffer." ”

The staff who delivered the wine and meat kept bending down and bowing their heads, their hearts going up and down, and their faces were also very respectful. for fear of angering the military leader in front of him and ending up with five horses and corpses.

"Mr. Lao went back to convey it."

Liu Zeqing said: "Our army is in Laizhou, and it will definitely be innocent. ”

"Yes, the villain must have conveyed it and said goodbye."

The staff hunched over and retreated cautiously.

Li Jiucheng looked puzzled, he didn't rob, what did he rely on to feed the soldiers.

"Lao Liu, are you burnt up?"

Seeing that there were no outsiders in the tent, Li Jiucheng hurriedly said: "Our army does not have a stable stronghold, what do we rely on to feed if we don't loot!" ”
