There must be a motor, and only with a motor can there be a precision lathe, and then various alloys must also be tried to be refined, as well as various new chemical materials.

These things have to come step by step, and they all have to rely on professional people to explore and experiment, if he is alone, it will definitely be no fun.

But now with these students, as long as these students learn well and are assigned to various fields of research in the future, the speed will be much faster.

It took a hundred years for the first industrial revolution in history to enter the electrical age, and he traveled to the Ming Dynasty, and he could directly take two steps of electrical vapor, and the theoretical results obtained by those scientists after a lifetime of calculation and verification were in his case.

If he does his best, has his guidance and teaching, coupled with the diligent efforts of these students, and of course, has to grasp the power to mobilize the full support of the imperial court, under the condition that these conditions are met, he does not dare to say that the information revolution will be carried out, but it will take a few decades to go through the steam and electric era of more than 100 years in history, it is still very promising!

He said so much to Fang Xiaoru, but also hoped that he could realize the importance of science and technology and not hinder his teaching.

Although Fang Xiaoru still felt unbelievable, he couldn't help but believe a little more when he saw him so confident.

Seeing Fang Xiaoru like this, Li Wei also quietly breathed a sigh of relief.

A month passed in a hurry.

After being busy for so long, now the college is finally on the right track, the students have learned pinyin, and they know more and more words, and at the same time, Li Wei has done some small experiments for them every now and then to attract his interest in science, and has also added a mathematics course.

While teaching, he was finally able to spare some time to be busy with other things, after the cannon test firing before, Zhu Yuanzhang asked him to supervise the Shenji Battalion, and he hasn't been there yet.

It's not that he wants to escape from laziness or something, it's just that the casting progress of the cannon is slow, and without the cannon, it's useless for him to go.

It has been so long since he came up with the method of casting new artillery, but so far, there are less than 100 Shenji cannons and Shenwei cannons in total, of which there are more Shenji cannons, there are 60 or 70 cannons, and there are only 30 Shenwei cannons.

It is really that the efficiency of the mud mold method is too low, and it will take a month or two to dry, as for the lost wax method, it can only be used in winter, and the weather is warm at other times, and the wax mold in the middle will melt before the mud mold is dried.

In fact, if he really used his brain, he couldn't think of a better way, but he didn't plan to put more effort into it, this kind of cannon was still too backward in his opinion, and it was not worth the effort.

Now the main thing is to hurry up and make the hydraulic chamber bed, this thing was originally there before the Watt steam engine came out, the technical difficulty is not too great, the reason why it has not been made until now, mainly because he is not available.

Well, I used to be lazy and escape, but now I'm really not available.

After arranging the affairs of the academy, Li Wei went to the Ordnance Bureau to pull up the cannon that had been cast, and took it to the Shenji Battalion.

The Shenji Battalion has now expanded to 20,000 people, and the garrison has expanded more than five times.

Li Wei had already asked people to say hello before, and when he arrived, Song Zhong, Zuo Wei and other former Qianhu officials, and the current commanders, had been waiting for a long time, in addition to these acquaintances, there were also some fresh faces, all of whom were above the level of a thousand households.

"Meet the Admiral!"

When Song Zhong Zuowei and the others saw Li Wei coming to the front, they shouted in unison very solemnly and bowed on one knee.

Seeing this, other military attachés also followed suit and saluted.

Li Wei chuckled, waved his hand and said, "Don't be so polite, let's get up quickly!" ”

He had never paid much attention to these false courtesies, and the fact that these people were suddenly so grand made him a little uncomfortable.

When Song Zhong and the others heard this, they all stood up, relaxed, and stepped forward to greet them warmly.

"Lord Admiral, you're finally back, I miss you!"

Du Yuan came up and said numbly.

"Your Excellency!"

Sun Lei also shouted in a rough voice, but he is a sincere person, and he will not be as sensy as Du Yuan.

Song Zhong, Jiang Long, Zuo Wei, and Lu Tang, who was transferred from the Ordnance Bureau to the Shenji Battalion by Li Wei, all greeted him.

There is also a Yang Dayong, because the establishment of the Shenji Battalion has been expanded now, he has risen again.

Most of them have now become commanders and commanders, training four or five thousand battalion guards.

The other thousands of households, some Li Wei looked familiar, thinking that they were former veterans, and some of them had no impression at all, and they should be newcomers.

"My lord, please come in, let's go to the camp to talk."

Song Zhong opened his mouth and stretched out his hand to clear his debut, and everyone also echoed:

"Your Excellency, please!"

"Okay, let's go in and talk about it, Lu Tang, you arrange for someone to pull these cannons in, and I'll take you to practice together in two days."

Li Wei agreed, and at the same time turned sideways and ordered Lu Tang next to him.

"Okay, don't worry, sir!"

Lu Tang agreed, Li Wei bowed slightly, and then walked inside the Shenji Battalion, which had been absent for more than half a year.

In the Shenji Battalion, those soldiers were practicing queues and various battle formations, and after Li Wei left, Song Zhong and the others were not idle, practicing and correcting the ideas on the premise one by one, and now they are all practicing decently.

It's just that since they followed Li Wei out to fight that battle, they haven't gone out again, and this time Li Wei came back and brought new firearms, which made their hearts suddenly feel a little hot.

The last battle was fought easily, and after coming back, Li Wei was made an uncle, and they were all promoted, which was a favor brought to them by Li Wei.

When they returned to their tents, they were seated in their own ranks.

Li Wei found that this tent was much larger and much better than the one before him.

Come to think of it, now in the military camp of 20,000 people, he, the commander, is almost equivalent to the level of the commander, and even due to the blessing of the imperial power, the status is higher than that of the ordinary commander, the status is different from the past, and the treatment is of course different.

"My lord, I knew that you would definitely not let us go, and sure enough, it has only been half a year, and you are back!"

Song Zhong said with a smile.

"Uh, hehe, of course."

Li Wei's face was slightly stunned, he smiled awkwardly, and at the same time made a note in his heart on his small notebook.

This Song Zhong really didn't open any pot, he was really going to give up, wasn't he forced back!

Song Zhong didn't know what Li Wei was thinking, and thought that his sentence had spoken to his heart.

After arranging the artillery, Lu Tang also walked in.

"My lord, I've arranged all those artillery."

"yes, okay."

Li Wei bowed his head and asked him to sit down as well.

Then he looked around at everyone and said with a smile: "Everyone has worked hard during the time I left!" ”

"It's not hard, it's not hard, we've always been practicing step by step according to the instructions of the adults, thanks to the wise teachings of the adults, the Shenji Camp can have what it looks like today!"

Du Yuan rushed to compliment and pushed all the credit on Li Wei.

Song Zhong frowned slightly, expressing dissatisfaction with his behavior of snatching words.

Sun Lei thought for a while and felt that he needed to keep up, so he said in a loud voice: "I think the same way!" ”

Zuo Wei and Jiang Long and the others kept smiling and waiting for their chance.

Li Wei chuckled lightly and asked, "What is the situation in the Shenji Camp now, let's tell me." ”

The Shenji Battalion has expanded from 5,000 to 20,000, and the changes are still very big, and he has to re-understand it.

Jiang Long immediately preemptively said: "Lord Hui, now the Shenji Battalion has expanded from the original one guard to four guards, with a total of more than 20,000 people, I and Zuo Wei, Song Zhong, and Sun Lei are the commanders, and Du Yuan, Yang Dayong, Gongxi, and Shi Jin are ......the commanders."

Jiang Long gushed endlessly, and gave a general description of the situation in the Shenji Battalion, and knew the current situation in the camp well.

Among these officers, they are basically those who Li Wei is familiar with, and only the last two are newcomers, and their names have one thing in common, that is, they are easy to remember.

With Jiang Long's introduction, the two also stood up in time and saluted Li Wei, who bowed slightly.

The Du Yuan next to him listened to the list of these military attachés, and felt a little aggrieved in his heart.

In the past, several officials of thousands of households, except for him and Yang Dayong, the others have been promoted to commanders, and Song Zhongjiang, Long Zuowei, and the three of them are also counted, he thinks that he is inferior, but Sun Lei, a reckless man, has also been promoted to command, and he is a little unconvinced.

In the past, Li Wei was not there, and he didn't reason, but now that Li Wei is back, he wants to seize the opportunity to fight for it.

After listening to Jiang Long's introduction, Li Wei nodded secretly in his heart This Jiang Long's ability is still very good, it was the multi-row three-dimensional queue he suggested at the beginning, and now it has been popularized in the battalion, and the effect is not bad, when shooting, it is no longer as long as before, and the firepower is concentrated a lot.

The current Shenji Battalion is basically divided into four guards according to the old model, and each guard is configured according to the way Li Wei used to, and the firepower of each guard is average.

However, Li Wei knew that this was not suitable for the firearms army, and in the armies of later generations, each establishment unit had a focus, such as an armored division, an infantry regiment, a cavalry company, or something, and anyway, they were divided into different arms according to the equipment configuration, so that they could coordinate and cooperate in combat to give full play to their respective advantages.

Li Wei plans to follow this model and adjust the Shenji Battalion.

"My lord, what are the arrangements for those artillery you brought?"

Song Zhong opened his mouth and said tentatively.

They had all heard that the new artillery pieces brought by Li Wei were extremely powerful, and now the commanders of their guards were thinking of grabbing a few more.

"My lord, I think it's better to put them all in my guard, and it's better for Lu Tang to use this thing for Lu Tang!"

Sun Lei said bluntly.

What he is bringing with him now are the original veterans, including Lu Tang and these military craftsmen.

It's the end of the month, ask for a monthly pass, thank you!
