The war raged in Hanzhong, and the lights of the capital were bright, and all the people poured into the streets to watch the lantern exhibition held by the royal family.

In the past, lantern viewing was a way of entertainment for officials and eunuchs, and it was a gathering place for literati and scholars.

On the fifteenth day of the first lunar month this year, no matter what kind of identity, regardless of gender, young and old, they all went to watch the lanterns.

Originally, Chongzhen hoped to make electric lights, but now although the bulbs can be made, and the bamboo filament has also been formed, there is no perfect vacuum technology, and the filament will soon burn out.

There was also no shortage of wires made of copper, so the electric lantern exhibition had to be abandoned.

However, to Chongzhen's delight, the simple hand-cranked generator has been successfully made and dozens of units have been produced.

In order to test whether the power generation was successful, he had to test it himself, and he was shocked many times before he was convinced that this cross-era object had been "invented" by himself.

At this time, Chongzhen and his party did not go to see the lights, but nested in a "laboratory" to experience the "fun" of electricity.

Zhou Yingluo watched Chongzhen touch the copper wire with his hand, but he twitched his hand as if he had been stung by an insect, but his face was extremely excited, very curious, and he also reached out to touch it.

"Oops!"

An exclamation aroused Tian Shouxin's curiosity.

"Grandpa Tian, this is so fun, crispy and numb, especially refreshing, why don't you give it a try?" Zhou Yingluo made it bad.

Tian Shouxin was suspicious, looking at the actions of the two masters, it was obviously not like a good thing, but looking at Chongzhen's expression, hearing Zhou Yingluo's words, he couldn't help but try.

He saw that the little eunuch kept shaking the handle, and there was no other vision except the sound of the machine turning, so he carefully pinched the copper wire.

"Wow...... What the hell!"

Tian Shouxin was startled and screamed, and immediately jumped up, almost throwing the generator out.

"Take it easy!" Chongzhen was not happy, "It took me half a month to make this thing!"

Tian Shouxin hurriedly apologized, and couldn't help but ask, "Your Majesty, what is the feeling of this Zaza?"

"It's electricity!" Chongzhen smiled, "Converted from a magnet!"

"Does the emperor want to use this to make fortifications?" Zhou Yingluo asked.

"That's not it, for now, electricity can only be used to light up the Kyoshi!"

"Lights up? Kyoshi?"

"Hehe, Father Tang, bring me the light bulb I made."

John Tang came in from outside, holding a crystal clear glass product in his hand.

Zhou Yingluo was immediately attracted by its beautiful appearance, and her big eyes couldn't stop looking at it.

Looking at the puzzled people, Chongzhen didn't explain too much. Take the light bulb and install it on the lamp holder.

"You can shake the generator!"

The little eunuch got the order, and immediately shook the handle at an even speed.

The generator generates an electric current, which is quickly transmitted through the copper wire to the lampholder, and the light bulb immediately lights up.

Immediately the room was as bright as a hundred candles!

"This is the electric light?" Zhou Yingluo exclaimed, "If you put him on the street, wouldn't it be like daytime!"

"It's not as bright as daytime, but it's enough to make people see the road." Chongzhen said with a smile.

Several people sighed, and they were even more surprised by Chongzhen's whimsy, this kind of thing is much more magical than the floor-to-ceiling mirror I saw a few days ago.

The little eunuch brought the finished lantern and put it on the bulb, which attracted Zhou Yingluo's amazement.

Half an hour later, the filament broke, and the room was dark again.

"What's going on? Broken?" Zhou Yingluo looked at the rapidly extinguished filament, a little lost.

"No way, we haven't been able to completely extract the air out of the bulb, so he can only light it on for a short while, and then it will burn out." Chongzhen is also helpless, who let there be no rubber trees in the north, although it is replaced by cow tendon now, but the effect is not very good.

"However, the ships of the Jinyi Guards in the South Seas have already set sail, and when they find that kind of tree, they can make the extraction equipment."

"Trees?" Zhou Yingluo questioned.

Before Chongzhen could explain, Wang Chengen came quickly, panting and rushing into the house.

Although he is the commander of Dongchang and can face the saint at any time, it is very unruly to come in such a gaffe.

"What's the emergency?" Chongzhen asked.

"There's news from Hanzhong! Zhang Xianzhong died at the hands of Azig!"

Hearing this, Tian Shouxin and the others were stunned, only Chongzhen's face did not change, "The wheel of history can't stop it!"

"Give me the secret!"

After reading the ten lines at a glance, Chongzhen knew that not long after Zhang Xianzhong rushed out of the inner city, he was hit in the heart by an arrow from Azig and killed on the spot, and he didn't even say his last words.

The Xian army was suddenly in chaos and was dispersed by the army led by Azig.

Fortunately, Li Dingguo was not in chaos, rushed over with his troops, and fought at a huge price to snatch Zhang Xianzhong's body, and finally retreated to Zhenba with 3,000 remnants of the army.

"This was four days ago! Now Li Dingguo should return to Zhenba, or he has withdrawn to Sichuan. After all, there is not one out of ten Xianzhong soldiers who went out to Hanzhong, and all the high-ranking generals, including Xian thieves, were killed in battle, and Li Dingguo was lonely and could not speak, so he must take Zhang Xianzhong's body back to Chengdu!"

Chongzhen muttered to himself, and the others didn't respond, but they just felt that the emperor seemed to care about Zhang Dingguo, but he didn't understand why he was mistakenly called Li Dingguo.

"Father Tang." Chongzhen thought for a while and spoke.

"The minister is here."

"When will the new firearms produced by the Arms Bureau arrive in Shanxi?"

"Back to the emperor, the grenades and explosives packs are enough, and they have been transported to Shanxi with the firearms instructor a few days ago.

It is believed that within 10 days, it will be able to be equipped to the front line in Shanxi, and within a month, it will be able to teach soldiers to use it.

100 mortars have already set off, just not enough shells. It may take another month to guarantee 50 shells for one cannon."

"It's a little slow. Now that Zhang Xianzhong is dead, Azig should soon clean up the lonely city of Hanzhong, and the people there will be slaughtered again......

Tang Ruowang didn't pay attention to the second half of the sentence, and hurriedly replied: "Your Majesty, all the new firearms produced in the past few months were sent to Liaodong, and now they are shipped to Shanxi, all of which have been produced in the past month, and the speed is not slow!"

Chongzhen smiled, he naturally knew that the production speed of the Arms Bureau was not slow, but he just felt that he couldn't keep up with the changes in the situation.

"I'm not saying that your Arms Bureau's production is slow...... Ay...... Go down, Wang Daban, you also go and help Father Tang prepare for our Divine Engineering Academy, and strive to cut the ribbon on the 20th day of the first lunar month as scheduled!"

Shengong College is an organization specially established by Chongzhen for the development of Daming science, the full name is Daming Royal Shengong College, which is comparable to Guozijian and specializes in scientific research and cultivating scientific and technological talents.

At the same time, in order to further improve the scientific level of the Ming Dynasty and the importance of science, he has prepared to divide the imperial examination into two and set it up as two kinds of scientific examinations, liberal arts and science.

This opens the door to the science of the Ming Dynasty.
