Because he did not learn history and geography well, in terms of Sichuan's products, Wang Li only knew the salt of Jingyan County.

In addition, it is the coal of Hanyuan County, and the iron of Panzhihua!

Zhang Hanru's "intelligence" is really right: the "Hanyuan" county hundreds of years later is really the "Hanyuan" in Lizhou;

The coal mines there have amazing reserves!

Forced labor mining is already being organized!

However, the "Panzhihua" that Wang Li is looking for should be the "Jianchangwei" who belongs to the "Sichuan Chengxuan Political Division"!

Back then, when Emperor Wanli's tax supervisor "pointed to the mountain to collect taxes", he did find iron ore in that place!

Judging from the reference point of Lushui, the "Panzhihua" of later generations should be there!

Hundreds of years later, the name of "Pangang" is really thunderous!

Now that he has found "Pangang", Wang Li will naturally not give up!

Even if the transportation is inconvenient, you will be able to get it!

Anyway, there is labor in this era!

Even if Zhu Zhishu didn't intervene, Wang Li would try his best to mine it and transport it out!

Now, for a project that can be completed for more than 700,000 yuan, Wang Li quoted a sky-high price of 7 million!

However, although the investment is large, the profit is considerable!

The bait has been thrown to Zhu Zhishu!

If he wants to make money, he will take the bait!

It doesn't really matter whether he takes the bait in the end or not!

At present, as long as he is the king of Shu and doesn't make trouble everywhere, that's enough!

"Is there really a sulfur and saltpeter mine in Sichuan?"

"Governor Zhang has confirmed, there will be no fake!"

Oh, yes!

In later generations, Sichuan was known as the "sulfur capital"!

Since there is sulfur and saltpeter, it is easy to do!

"Recruit 50,000 conscripts and organize mining as soon as possible!

Refining gunpowder is a top priority, and you are personally responsible!

Cows, horses, and mules for transporting gunpowder must be prepared in advance! ”

"Don't worry! The people have been wandering around the yamen all day long, just waiting for us to recruit conscription!

The cattle, horses, and mules in the hands of the common people can easily collect thousands of heads for a little silver! ”

"Report ...... Chang Gong: The day before yesterday, the King of Shu summoned dozens of Zhu clan relatives! After their secret discussion, a team of more than 300 people set off for the south today! ”

Oh?

South?

This guy really took the bait!

Leave him alone!

At this moment, whether he takes out the money or not has nothing to do with his own road construction!

is still the same sentence: the silver in the hands of the royal family and the rich squires has always remained in Sichuan!

As long as the main road to Dechuan is blocked, the silver will be your own sooner or later!

Of course, that was the case of turning his face with Zhu Youzhen!

At this time, if the surname Zhu is willing to pay, both hands are welcome!

After all, there are still more than ten years before the time to turn the other cheek!

What's the harm of being able to get the money early in a peaceful way?

Perhaps, through this bait, you can also reduce the hostility of the King of Shu towards himself!

At that time, ask him to write a letter and take the initiative to "clarify" the causes of death of several county kings, and Zhu Youzhen has no reason to move himself!

……

On this day, Chen Wangting and Zhu Kezhen arrived at the dock at the same time!

Because, Chen Wangting's arrival was not to receive his own order, but to bring two good news!

The mortar that Wang Li wanted, samples have already been made!

The cement researched by the Fujian Ordnance Bureau, Chen Wangting also brought samples!

However, it also brings bad news!

Xu Guangqi died of illness!

In the eyes of Wang Li and later generations, the principle of firing and detonation of mortars is very simple!

It's really going to work, but it's not that easy!

In this era without an industrial base, it is even more difficult to climb to the sky!

Xu Guangqi dragged his elderly body, and it took him more than two years to finally make a sample!

The test launch in Fujian was very successful!

Xu Guangqi's sick body can no longer support it!

Before dying, he told Sun Yuanhua in detail about the firing and detonation principle of the mortar, as well as the firing principle of the rear-loading rifled gun!

In this regard, Sun Yuanhua is really sad and happy!

After finishing Xu Guangqi's funeral in a hurry, he immediately drove the big ship to sea!

"Am you not mistaken? Is Sun Yuanhua really going to Portugal? ”

"Factory father, Governor Sun can't help it!

The craftsmen of the Fujian Ordnance Bureau can only make some armor and potassium bows and arrows!

If you really want to cast the Hongyi cannon, you have to be a professional red-haired cannon caster! ”

"Alas!"

Wang Li sighed, thinking deeply!

In the Ming Dynasty of this era, there were no technicians who cast cannons!

There is no systematic research and industrial base for cannon casting!

Few people can understand the things that Xu Guangqi translated!

The mortar in front of him was completely cast by Xu Guangqi!

If you want to cast more mortars and Hongyi cannons, you can only go to Portugal and "import" technicians!

At present, this is the fastest and most economical way!

Alas!

Unexpectedly, Xu Guangqi, the only "modern" scientist in the Ming Dynasty, left quietly like this!

"Factory Gong, Governor Sun is a guilty minister, and it is not suitable to report the funeral to the imperial court......"

"That's right!

Xu Guangqi once served as a squire in the Ministry of Rites, a scholar of Wenyuan Pavilion and a deputy assistant to the cabinet, so he should report the funeral to the imperial court as soon as possible!

Whether the Lord of Long Live posthumously bestows him with official positions, or whether he seals his children and grandchildren, we don't care!

At this time, in the name of the West Factory...... Uh, no, in the name of the Fujian Ordnance Bureau, send 100,000 taels of silver to his wife and children! ”

After that, Wang Li was sighing again!

In this era when the imperial examination system is prevalent, it is difficult for many of Xu Guangqi's Western works to be popularized!

During the Ming and Qing dynasties, the first opportunity to catch up with Western learning and popularize modern science was unfortunately lost!

I really don't have the ability to change history!

Even if I tried to work hard!

Liu Ruye's "resurrection from the dead", Wu Sangui's "resurrection from the dead", and Li Zicheng and Zhang Xianzhong who appeared in vain are the best proof!

History, perhaps, really can't be changed!

But there is something that can be done!

"Pass the order: recruit children between the ages of eight and fourteen in Shuzhong to study Xu Guangqi's "Geometric Originals", regardless of gender, the number is not limited!

A year later, the factory took the exam in person!

Those with excellent results will be rewarded with 50,000 taels of silver!

I was hired as a mathematics lecturer again with a monthly salary of 1,000 taels! ”

"Factory, this ...... I've also seen Geometry, but ...... I really can't read it!

If you let children between the ages of eight and fourteen study without a special teacher to guide you, I'm afraid it's ......."

"Who says there are no teachers? Am I not a teacher?

The Portuguese cannon casters brought back by Sun Yuanhua, aren't they also teachers? ”

For teaching "Geometric Originals", Wang Li, a scumbag, still has enough confidence!

After all, Geometry is the foundation of mathematics!

As long as you have completed nine years of compulsory education, everyone can do it!

Wang Li's self-confidence, Chen Wangting has no doubts.

When he was in Fujian, every time Xu Guangqi mentioned Wang Li, he regarded him as a saint!

A saint indeed!

It took Xu Guangqi and Matteo Ricci several years to translate the six volumes of Euclid's Originals!

And Wang Li, in just two nights, translated the remaining nine volumes of "Euclid's Originals"!

Not only the errors in the first six books are pointed out, but also the errors and omissions in the original Euclid!

The firing and detonation methods of mortars and breech-loading rifled guns surpassed the Portuguese and Dutch cannon casting theories!

In fact, while Xu Guangqi respected Wang Li as a saint, Wang Li also respected Xu Guangqi as a saint!

Because, he was the pioneer of modern science in the feudal period!

Hundreds of years later, many of the Chinese words used in mathematics originated from Xu Guangqi's first translation!

The end of modern science is mathematics!

The source of modern science is also mathematics!

Xu Guangqi brought modern mathematics to the land of China, but unfortunately, no one knows how to cherish it!

Wang Li even felt that the basic science of the Qing Dynasty lagged behind the world, and the isolation of the country was only one of the reasons!

Another key reason is that no one has mastered advanced basic mathematics!

That's it!

The pioneers of modern science, gone!

As long as there is a successor, this pioneer will leave no regrets!

It's just that......

Why is the mortar cast by this pioneer so bulky?

It's really stupid!

This posture, even if there are no three hundred catties, there are two hundred and seventy-eight!

Four strong gunners, with all their strength, lifted it off the ship!

Moreover, this cannon pellet ...... It's too big, isn't it?

To say the least, there are twenty or thirty pounds!

Nima!

Is this a mortar or a howitzer?

Throw such a heavy thing into the barrel and not blow up the chamber?

Even if you don't explode, how far can you shoot?

"Don't worry, the factory will never blow up!

When we were in Fujian, we had already test-fired many times!

If you use a 45-degree shooting angle, you can shoot more than 100 zhang! ”

"Then ...... Give it a try!

The little col on the other side of the river, see!

Approximately 200 meters...... Belch...... About seventy zhang!

That tree on the col is the target!

If you can shoot, you will be rewarded with 5,000 taels of silver per person! ”

I'll go!

Five thousand taels!

The factory made a move, and it was really different!

In addition to the surprise, the four gunners skillfully adjusted the direction, range, and adjusted the angle of fire.

When you're ready, remove the stopper at the end of the projectile and slowly stuff it into the barrel.

"Boom!"

The explosion of the disembowel was deafening, and black smoke was everywhere!

With a whistling sound, the cannon pellet crossed the Jinjiang River and landed accurately on the earthen col!

"Boom!"

In the sound of the explosion, the mud and sand rose several feet high!

The smoke and dust on the other side had not yet cleared, and the deafening sound of artillery exploded again!

After three shots, the small tree with thick wrists finally fell slowly!

"Good! Good! Very good! Reward! ”

Wang Li was overjoyed, and quickly jumped into the boat and went to the col to check the scene of the explosion.

The crater was bigger than a basket!

Wang Li was silent!

Nima!

Mortars are mainly used to kill and injure enemy soldiers, and they are not used to break through walls and siege cities!

It's lightweight and flexible!

Xu Guangqi, why did you make the projectile so big?

The power after the explosion is even more powerful than the Hongyi cannon on the Jingshi City!

The barrel was made so thick, it turned out to be for a reason!

If you don't make a little more skin, you will explode!

"Change! I have to change it again!

The weight of the cannon pellet, at least double!

The weight of the entire gun body should be lifted by two people!

The range can be increased a little better! ”

"Factory, you...... If I had said that earlier, I would have been able to send samples last year...... If you want to change it, you can only wait for Governor Sun to return! ”

"Change, must change!

I didn't make it clear!

Mortars are used at close range!

I ask for one person and one horse to be carried, and run away after the fight!

Got it? ”

"Well, it's actually very easy!

As long as Governor Sun comes back, it will be done soon!

By the way, this is the cement you want...... This thing really works! ”

In the canvas bag in front of him, the blue-gray powder was grinding finer than Wang Li imagined!

Wang Li didn't ask about the recipe first, but about the grinding method.

"Factory father, this is not made of stone pestle little by little, but invented by Lord Xu...... Big, big grinding device!

This thing, about three feet in the shape of a barrel, has a hollow inside, and contains dozens of fist-sized glass balls!

This iron thing can be turned in half an hour at most, and it can grind all kinds of particles into powder!

Very fine powder!

Once you can grind a bag! ”

Chen Wangting's face was full of admiration for Xu Guangqi.

Wang Li was also surprised!

Judging from Chen Wangting's description, Xu Guangqiming's grinding device should be a "ball mill" with simple functions!

The ball mill has a simple structure, and it can be manufactured at the level of science and technology in this era!

Xu Guangqi can have such a brain, it is really admirable!

If you replace the glass balls with steel balls, the grinding speed will be even faster!

If you want to scale up production, you need bigger and more ball mills!

Hundreds of years later, what method is used to grind cement, Wang Li really doesn't know!

But don't worry!

Let's use the ball mill for the time being, and then slowly improve it later!

"By the way, you've tried the performance of this thing?

What exactly is it made of? ”

"Factory father, Lord Xu visited many craftsmen, and after only dozens of attempts, he developed the correct formula!

It's actually very simple, the main ingredients are limestone, clay and slag!

As long as the mix is in the right proportion, and then follow the method of hot workouts you said, it can be easily made! ”

It's easy!?

Scold!

Unexpectedly, people in ancient times were also very smart!

Just a little bit of it!

In this era, Chinese people are no worse than foreigners!

As long as there is enough silver, only enough time, as long as all conditions allow, and then give them the opportunity to tolerate mistakes, they can also make epoch-making things!

"Very good! Hurry up and find some sand and gravel and try it now! ”
