After the invention of electric light, it will not only bring convenience to production, but also bring a lot of convenience to life.

However, after the trial production of this electric lamp, it was not immediately installed in various factories, and it was not immediately put into civilian use, and there were many taboos at that time.

Therefore, as soon as Xu Fuyuan and Xia Yunyi developed the electric light, they began to plan how to install it in the palace.

Of course, tungsten has not yet been mass-produced, and the old generators do not have enough power to bring too many large bulbs, so it will take a while to actually use electric lamps.

Fortunately, this silicon is the second most abundant element in the earth's crust, and pure monocrystalline silicon can even be found in nature, so Song Yingxing quickly developed the rail steel sheet.

At this point, both the electric motor and the large generator can enter the trial production stage.

Just when Xu Fuyuan and Xia Yunyi were frantically developing electric motors and large generators, there was another good news from South Asia, the railway extending from the city of Ava in Donghu to Kandahar, an important town in the northwest of South Asia, was finally completed, and the railway branch lines and highway networks in various provinces were also completed with capital construction, that is to say, the entire South Asia was included in the railway network of Daming, and in the future, it could even reach Kandahar by car from the capital!

In addition, the harvest in the second half of this year in the 15 provinces of South Asia was quite good, and prices began to fall slowly, and this newly expanded territory finally passed the difficult period and embarked on the road of normal development.

Although Zhu Cijiong was very disgusted with Ah San in later generations, after a meal of wool shearing, his disgust was not so strong, after all, they had made a huge contribution to the treasury of the Ming Dynasty.

Besides, now that South Asia has become the territory of the Ming Dynasty, and all the people there are already the people of the Ming Dynasty, he naturally doesn't want these people to live a poor and difficult life anymore, and the poor mountains and bad waters are easy to make the people miserable, and if the people there are really miserable, it is not conducive to the stability of the entire Ming Dynasty.

Now, with the rail and road network, and the four royal companies working with local officials to implement the successful business model of the Ming Dynasty, these people will slowly live a prosperous life, at least without worrying that they will rebel at every turn.

A few days after the good news from South Asia arrived, there was also good news from the northern part of Xinjiang.

According to Sun Chengzong's report, he had led his army to repair the railway and pillboxes to the north of Nuer Gandusi, and did not encounter much resistance.

Moreover, he has sent 20,000 iron cavalry of the Guanning army, respectively, to the northernmost Manjingwei and the easternmost Yimuhewei, according to the reports of the leading generals on both sides, there is no large number of enemy troops found along the way, and the nomadic tribes are also quite enthusiastic about the arrival of the Ming Dynasty, and they also want to return to the arms of the Ming Dynasty.

Now, he has asked the 20,000 iron horsemen to carry out simple repairs to the original guards of Manjingwei and Yimuhewei respectively, and sent enough grain and grass for them to temporarily garrison there, only to wait for the next summer, when the ice and snow melt, the railroad and pillboxes will be repaired, and this large territory in the north will be recovered!

Zhu Cijiong didn't expect that the recovery operation in northern Xinjiang would go so smoothly, you must know that it is millions of square kilometers of land.

In fact, it is not surprising that the population of the whole world is far from reaching the size of the future generations, and even some places with fertile land and good weather are still not filled.

However, there are no absolutes in everything, and there are really people fighting for it later, and Daming has suffered huge losses because of this, of course, these are all later words, so I will skip it here for the time being.

After the good news from Northern Xinjiang spread, Song Yingxing brought another surprise to Zhu Cijiong, he actually purified the metal chromium!

Song Yingxing can purify chromium so quickly for a reason, it seems that there are many historical records, the Qin Dynasty seems to have discovered the element chromium, Qin Shihuang's sword crossed a layer of chromium, and chromium generally exists in chromium-lead ore, this lead has been recorded for a long time, this chromium should have been there for a long time, but it is not called this name.

In any case, he finally sorted out the three elements that the emperor asked him to develop first, and according to Zhu Cijiong's requirements, he first developed and purified tungsten, then silicon, then chromium, and then followed him.

Song Yingxing was a little confused at first and didn't understand what it meant, but now he seems to understand a little.

This tungsten wire can be used to make something as magical as a light bulb, and he has known that silicon steel is a necessary material for making electric motors and large generators, so what is the use of this chromium?

There was no need for him to think about this, Zhu Cijiong quickly sent him several stainless steel formulas and asked him to organize his subordinates to develop them.

Stainless steel? Can this steel not rust!

It's no wonder that he can't understand it, because there is no oxidation at this time, the reason why iron rusts is that it is oxidized, and chromium is an element that is difficult to oxidize at room temperature, so it is difficult for steel filled with chromium to rust.

This Zhu Cijiong can't explain to him for the time being, what oxygen and oxidation you say to people at this time, it's strange that people can understand it, anyway, he just needs to make it according to the recipe, and this steel can really not rust!

Surprises kept coming, Zhu Cijiong felt a little overwhelmed, he is now in a state of extreme excitement almost every day, this person is prone to accidents when he is excited.

No, Song Yingxing's surprise has just passed, and Princess Anna has given him an even bigger surprise, she is also pregnant!

This really made him crazy, the reason why he never had children before was not because he didn't like children, but mainly because the periphery of Daming was not stable, and he still needed to fight in the Quartet.

However, since taking the Mughal Empire and Batavia, Daming's periphery is basically stable, so he immediately relaxed the restrictions and prepared to have children.

Of course, the emperor's child can't be born randomly, although there are strict regulations on the succession to the throne, which is the so-called "standing up for the heir, not for the long, and not for the virtuous." But who can guarantee that there will be no competition for the throne after the prince has more children?

Therefore, he wanted to let Queen Qin Mingyue give birth to a prince first, and then break everyone's thoughts.

Although he has been living in the harem during this time, he is still very careful, like other concubines, he will not stay, except for this Princess Anna.

Because she has the right to inherit the Habsburg dynasty, the prince and even the princess she gave birth to can inherit the position of the duke or king of the Habsburg dynasty, there are four or five kingdoms under the rule of the Habsburg dynasty, more than ten principalities, if she wants to give birth to an emperor's eldest son, it is a big deal to send it to Europe and help him get a throne!

Presumably his brother, Ferdinand III, the Emperor of the Holy Roman Empire, will definitely welcome it, because the Holy Roman Empire is about to fall apart, and he can't wait for the Ming Empire to intervene and help him stabilize the throne!
