As soon as he arrived in Beijing, Sun Yuanhua received a 'cordial care' from Zhu Youzhen, and then he didn't care about resting, and hurriedly returned to the General Bureau of Ordnance.

However, when he had just stepped through the doors of the Artillery Division.

The corners of his mouth couldn't help twitching, and he said to a small official in charge of security at the door: "... Artillery Division.. What about people!! ”

The little official seemed to have just arrived.

As soon as he opened his mouth, Sun Yuan turned into thunder, and only listened to him say: "Artillery Division? Didn't they all go to the General Administration of Industry to do a side job? ”

Almost using up the last bit of strength, Sun Yuanhua opened his mouth and said, "Do you know when you left..."

"I don't know.."

On the other side.

Inside the General Directorate of Industry.

The previous junior, and now Wang Yisi, are looking at these craftsmen with an eager face.

I only heard him say: "Brothers, work hard! The last little problem of the steam train is about to be solved by us! After today, Daming will have the first complete set of train technology! ”

Zhu Youzhen demanded that the railway immediately start planning and construction.

However, the technology of the train needed to be finally adjusted and determined, so the craftsmen of the Royal Ordnance Bureau were once again "borrowed" by Wang Yisi.

But he didn't wait long for Wang Yisi to be happy.

I heard an angry voice from outside the hospital: "Wang Yisi! Get the hell out of here! ”

Sun Yuanhua is now furious, he finally came back from Guangdong and Fujian after such a big circle, and as soon as he arrived in the capital, the emperor sent a message to let him step up production.

For a moment, Sun Yuanhua thought that he was about to be reused.

Okay...

The emperor who made himself expedite production probably didn't know that now all his craftsmen had arrived in the production workshop of the General Administration of Industry.

Voices outside the hospital are heard.

Wang Yisi said secretly: "Oh no! It must be that Sun Yuanhua is back! ”

Although I didn't know where Sun Yuanhua had gone, and I didn't know how long Sun Yuanhua was going, the matter was urgent at that time, and Wang Yisi couldn't contact anyone, so he had to ask Xue Fengxiang's acquiescence to make a move.

But now the Lord has returned...

"Wang Yisi! Don't make any excuses in front of me, I only have one word now, immediately! Right away! Give me back all my people now! ”

Sun Yuanhua's voice spread far away, and the two of them were outside the courtyard, and the craftsmen in the courtyard could hear it.

"Shhhhh It seems that Lord Sun is back! ”

"Ahh Oh no, no one has told Master Sun about our time here! ”

... Everyone gasped.

"Okay, you Wang Yisi! Well! It's really impressive to not see you for a few days, you actually dare to rob my people..."

Theoretically speaking, Wang Yisi has a higher position and a higher grade than Sun Yuanhua at present.

But the two always like to get together on weekdays to study some industrial products.

After coming and going, they also recognized the friendship of brothers, but the age gap between the two is not small, and outsiders will think that they are uncles and nephews.

That's why Sun Yuanhua dared to ask for someone from Wang Yisi without any scruples.

"Gassless! Let off steam! Big brother, little brother really has no way to make such a decision, you see that on weekdays, I can be such an unreliable person...."

As he spoke, Wang Yisi rolled his eyes back and motioned for him to continue staring at the train's perfect work.

And he keeps saying good things.

hugged Sun Yuanhua into the house to drink tea.

"The emperor wants to build a railway from Beijing to Tianjin Port, but it has already been planned to be built... The most critical steam train, but it has not been perfected for a long time, brother, can I not be in a hurry."

While making tea for Sun Yuanhua, Wang Yisi said with a smile.

"Yes.. It's understandable to do things for the emperor, but who am I waiting for not to share the emperor's worries and solve problems for the court... You have to leave the manpower of my artillery department, and seeing that the emperor is going to start large-scale firearms production again, what will you let me do..."

After speaking, he glanced at Wang Yisi.

"The machines in the workshop don't move on their own, so this guy is today! I must have to take it with me! ”

"Let's go! You have to go, but can you be more lenient at this time, and by this time tomorrow, brother, don't worry, I will definitely let you take it away. Wang Yisi said as if he was still bargaining.

In the end, Sun Yuanhua lost his temper and turned to leave, because he knew that what Wang Yisi was doing at the moment was also very important.

"Alas. This little four really is! I'll have to find a way to find someone else to top it."

....

Intrauterine.

Zhu Youzhen sat lazily on the recliner in the East Warm Pavilion, looking at the system interface.

"So much time has passed... The system points did not increase by a single point.."

Now preparing for the war against Mongolia, in fact, Zhu Youzhen's heart is just to find a way to balance the situation and weaken the power on the steppe.

What really cares about him the most.

It is Annam and Luzon, as two places located in Southeast Asia, not to mention the fertile land, but the strength is still weak.

It has also changed hands many times in history, and anyone who comes can step on a few feet.

Annan is okay to say.

If Luzon wants to fight, it will inevitably infringe on the interests of the Dutch, so Zhu Youzhen is ready to take Annan first, and then turn his head to clean up Luzon.

As for the Dutch ..

Zhu Youzhen could only say silently in his heart: "Calculate the time... Someone is going to start making trouble with the Dutch.."

"Wait!"

Relatively high-end technology often needs a large number of pre-technology or supporting technology as support in the system mall.

And because the points were recalculated after the system update, Zhu Youzhen, who was shy in his pocket, had not used the search function of the system mall for a long time, and now he just opened it.

Zhu Youzhen found out..

"Soil blast furnace smelting technology"

Refractory Brick Technology

... Zhu Youzhen's eyes lit up instantly, the most important thing in the industrial revolution is steel, to be precise, if you can replace the degree of development with a number, it is steel production.

After seeing that only 1 point was needed, Zhu Youzhen chose to redeem it without hesitation.

【Ding! Congratulations to the host for obtaining the "Soil Blast Furnace Smelting Technology" and "Refractory Brick Technology", and consume 2 points this time! 】

Open the book.

Zhu Youzhen patiently looked at it, the so-called soil steelmaking is the use of refractory bricks to build a small blast furnace, heating iron ore to more than 1600 degrees, to obtain molten iron with high carbon content.

In this way, the primary product called cast iron was successfully obtained, and then only a steam engine was used as a power to continuously blow oxygen into a converter filled with molten iron, taking away the carbon content of the molten iron.

After that, you can get different grades of steel, the most important thing is that there will hardly be too much technical difficulty if you do this, and it can be achieved with the scientific and technological strength of the Ming Dynasty today.
