Lu Ning was enthusiastic about building a steam engine or even a gasoline engine, but he suddenly found that due to the difference in weights and measures, the previous data could not be used directly.

In this case, he couldn't use the weights and measures of the Ming Dynasty to calculate a standard atmospheric pressure, what was it?

Besides, he didn't know what aluminum wire was, so he decided to use copper wire instead of aluminum as a conduction wire for the power system.

However, the casting process in this place cannot achieve the corresponding length and fineness of the copper wire, and even if it is barely done, it is not strong.

Just as he was thinking that he was about to make a copper wire more than thirty miles long, Zhu Yuanzhang immediately found him.

"Zi'an, don't harm my Daming's copper, okay? The officials of the Foundry Division have come to sue you, and now it hurts Daming to mint a batch of new money without copper. ”

You must know that copper was a resource strictly controlled by the imperial court at that time, and in the early years of Hongwu, because he wanted to mint a batch of Hongwu copper coins, there was no copper, and Zhu Yuanzhang almost died.

At that time, Shen Wansan's family was rich, but they were all Zhiyuan Tongtong to Zhengtong Treasure of the previous dynasty, and they couldn't be directly circulated in the market.

Zhu Yuanzhang was anxious when he saw it, we don't have copper in our hands, why do you have those in your hands?

So he found an excuse to send Shen Wansan to Yunnan, seized the copper, and then opened the furnace to recast it.

Ten years after the founding of the country, copper is still a scarce resource.

At this time, Lu Ning was also directly dumbfounded, and he said helplessly.

"Uncle, didn't you say that you want money to give money to people to give people, I just want to use some copper, why are you so reluctant?

"It's not that we can't bear it, it's a pity that these things are in short supply now, otherwise you will wait for another twenty years."

Lu Ning was anxious at the time, and said immediately.

"Let's make it first one night, and you're going to hit us with these things, aren't you worried at all."

Zhu Yuanzhang didn't think so.

"Anyway, our Ming Dynasty's bows, horses, swords, and swords are also advanced enough, not to mention the firearms battalion composed of three hundred rifles you contributed. Is there a machine like you said, we are all the best in the world, what's the use of building it? ”

At this time, Lu Ning completely lost his temper, these rifles were used by those sailors when he pacified the Japanese and became the general of Pingkou.

Later, when he came to the Beijing Division, he directly transferred those people over and formed the first firearms battalion of the Ming Dynasty.

It's not that he doesn't want to develop this army quickly, it's a pity that signing in that job is really face-seeking.

At the beginning, there were 3,000 rifles and millions of rounds of ammunition, and there was no problem, but now what comes out when I sign in is quite touching.

In the early stage, it was just some modern cameras, pencils, telescopes and other gadgets.

Recently, he was speechless when he signed in, and he actually signed in a million boxes of "cutie" brand safety umbrellas!

This thing gives me Daming, just like that donkey, it's useless.

So he was cheeky and didn't dare to explain, and quietly asked someone to put these things into the hole under the duke's palace.

With a depressed face, he boiled water at home, the water boiled, and he kept putting the lid on the kettle.

The two ladies kept reminding him, but he told them to enjoy the spectacle.

Lu Ning said helplessly.

"Two ladies, don't you think it's the greatest wonder in the world, and you don't see anything in it?"

Li Xinmin: "It doesn't matter if the concubine is gone. ”

Xu Miaojin was speechless and said very entangledly.

"People only accompany you twice in ten days, so you ask me to watch this?"

After Li Xinmin left, Lu Ning hugged Xu Miaojin.

There is no way, first make the beauty happy, and then he can get better, and after the beauty falls asleep, he sits up next to him.

Then he muttered silently.

"Heavenly Spirit, Earth Spirit, this time the sign-in must be OK, let me sign out the engine, I hope God bless Daming."

At this time, an interface appeared in front of you: since you have signed in for two consecutive years, you will be given the opportunity to draw five consecutive draws of the gift package. Do you want to participate in the lucky draw?

Lu Ning immediately responded with faith.

The interface in front of me turned into a large turntable, and after a while, an international kilogram prototype suddenly turned out.

This time it's like opening a hanging.,After a while, I signed in to the rice prototype.,The second prototype.,And the prospecting encyclopedia and the industrial encyclopedia.。

He almost jumped in excitement.

"I'll go, this is simply an artifact to revitalize the Ming Dynasty, with these three original weapons and these two Daquan, my strength can beat the entire Daming!

He put these things away very carefully, and then gently pushed Xu Miaojin.

Xu Miaojin didn't bother to open his eyes and say a word.

"Zi'an, don't make trouble, people dream of giving birth to a baby, you still have to choose a name."

In reluctance, he was finally awakened by Lu Ning.

Lu Ning whispered in her ear: "Miaojin, I found that you are getting more and more beautiful, why don't we change the way to have a baby?" ”

This matter has always been led by Lu Ning, and the reason is also bright, Xu Miaojin has no intention of refusing, of course, the consequence is that the next day, Xu Miaojin did not get up to recite the Buddha, but slept at home for a day.

And Lu Ning looked at the two panda eyes and saw Zhu Yuanzhang with an annoyed face.

"Uncle, who are you angry with?"

Zhu Yuanzhang snapped and threw some folds in front of him: "Bad morals, what are you saying and doing, isn't this holding the soles of your shoes and calling them in our faces?" ”

Lu Ning took those folds and looked at them, and it turned out to be all folds from the Ministry of Rites.

According to the recital, the children of several lords and ministers frequently went to the books and apartments run by the imperial court to have fun, and all of them contracted diseases, which caused a wave of infamy from the government and the opposition.
