"Lord Liu, thank you very much, welcome to our Goryeo guest ......"

"Gongzi Liu, if Gao Li can get through this time, we will definitely remember your kindness......"

With the approval of Emperor He Yu, everything is not a problem.

Liu Huayun first sent a team of Imperial Forest Army to the Shenji Battalion, selected a few of the worst old-fashioned cannons, and only equipped them with less than a hundred shells;

But Rao is like this, when sending Li Chengzan and the others away, he and Yin Jieshu beside him still couldn't hide their excitement and kept thanking them.

At the city gate, looking at the Goryeo mission and the Imperial Forest Army escorting the cannons, disappearing from the end of sight, Liu Huayun turned around and walked towards the city......

Time is like an arrow, the sun and the moon are like a shuttle, and seven or eight days are fleeting!

Bang bang bang ~~~, in the martial arts arena of the Horse Mansion, there are constantly gunshots.

As the wooden rakes were pierced one by one, more than 100 people, including Lu Feng and Guo Jing, were already proficient in the operation of muskets, but each person only had three bullets per day, which was indeed not very enjoyable;

And once the time for shooting is over, hundreds of push-ups, pull-ups ...... This kind of physical training is also extremely painful for them.

"Xianggong, is this a generator?"

"This thing can really replace candle lighting......"

In a renovated wing room in the inner house, I looked at the big guy in front of me, which was one person tall and thicker than a bucket, and the three glass covers connected by copper wires wrapped in cowhide;

Dong Xiaowan and Lei Tingting were asking excitedly.

Zhao Lingxin next to her was also looking forward to it, and the mobile phone was playing with her hand at the moment, so she was not unfamiliar with the substance of electricity.

"Let's try, I hope it works, if it doesn't work, I have to revise it......"

With a faint smile, Liu Huayun motioned for them to put the ignited charcoal fire into the furnace mouth first, and then fill it with coal blocks with an iron shovel in turn.

This so-called coal-fired steam generator, but he recruited eight or nine of the best mold craftsmen and blacksmiths in the capital to get up early and work late to make abrasives, smelt metal, and cut magnets....... It was repeated many times before I could barely get the original right.

As for whether it can successfully generate electricity all at once, it's really hard to say;

However, once successful, the rated current of 220 volts and six kilowatts was still untouchable, and there were no insulated wires in those years, so he had to temporarily replace plastic and rubber with cowhide and wrap the copper wires.

As the bellows under the furnace were constantly pulled up, black smoke continued to come out of the chimney outside the chamber, and the clean water in the furnace gradually boiled, and the steam began to push the impeller above to rotate......

"It's lit, the round glass that Xianggong made is really bright......"

Looking at the tungsten lamp that flickered and dimmed overhead, and finally gradually brightened, Lei Tingting and Dong Xiaowan smiled excitedly.

"Silly girl, I said that this is called a light bulb, as long as there is constant coal and water, our house will be as bright as daytime at night in the future......"

smiled coquettishly, and the relieved Liu Huayun patted their fragrant shoulders, the corners of his mouth were full of comfortable smiles; In order to make these tungsten lamps, he tossed for several days.

Blowing glass covers is better to say, smelting and pulling tungsten blocks to make tungsten wire, in this era of no electricity and no machines, it is absolutely difficult.

Fortunately, the hard work paid off, and with a super high IQ and the ability to check the Internet at any time for argumentation errors, the coal-fired steam generator and tungsten lamp finally succeeded.

The next step was to make tools for electrolytic extraction of ethylene, to the nearest crude oil storage site, to the border of Jinan, to extract crude oil, and to open a factory to refine gasoline, diesel, kerosene, and ethylene, which he was very interested in making plastics.

Liu Huayun is so anxious to get plastics, first, the containers for large-scale production of daily necessities such as toothbrushes, toothpaste, and shampoo need to be used;

In addition, whether it is insulated copper wire or insulated aluminum wire, it cannot be made without plastic.

After all, going to Hainan Island, thousands of miles away, to buy rubber will not be possible in the short term until a mechanically powered ship is made.

And the cowhide is difficult to guarantee that it will not leak electricity for a long time, and it is used on a large scale in the house, in case it hurts his wife and those little girls, he will regret it.

"Xianggong, the generator is ready, can you make this mobile phone?"

After Zhao Lingxin returned the mobile phone with little power to Liu Huayun, he looked at him lightly.

"This? It won't be possible in the next few years, but before it breaks, as long as we record all the manufacturing methods and let the children learn to use them, we will be able to make it one day......"

With the fragility of the smartphone, Liu Huayun really can't guarantee how long this thing can last, don't say that Zhao Lingxin wants to have it, and he doesn't want to lose this, the only treasure that can be used to contact his previous life.

Fortunately, the solar power bank can still be used, and it is best to compile and save all the books that can be recorded for research;

There is no shortage of rare earths in this world, as well as gold, magnesium, branding, zinc..... and other precious metal raw materials, as long as the technology is mature, radio, television, and mobile phones should not be a problem.

"Hmm~~~, the last time you and Sister Ruoping were co-ordinated, the unfinished physical and chemical basis;

Wan'er and Tingting and I have finished it in the past few days, but I don't know what it takes to make a mobile phone? If you have time......"

In the past few days, Liu Ruoping accompanied Liu Ruoxi, Meng Yushi, and Alice to check the decoration progress of restaurants, shops, and beauty salons;

Zhao Lingxin, Dong Xiaowan, and Lei Tingting copied the books according to Liu Huayun's request.

Although they can't understand those physical and chemical knowledge, let alone how to make mobile phones, there is a husband who knows everything, Zhao Lingxin still couldn't help but ask with hope.

"This? The phone has a processor, a display, a battery, ...... and many other parts and components;

Some of them will also involve trade secrets, and you can't find them on the Internet, but you don't have to worry, I have my own way, Lingxin, Wan'er, Tingting, you can copy these books first......"

Liu Huayun transferred hundreds of thousands of dollars to Swiss banks, although it is not much; But in the future, you can do another live broadcast to pit some gifts or something, and it is not too difficult to buy some overseas employees to steal internal information.

Therefore, he found the basic theoretical books on mathematics and geometry in his previous life, and said to Zhao Lingxin with a smile.

"Master Pony, can we go back?"

After laughing with the three girls for a while, and telling them not to touch the copper wire of the generator, Liu Huayun walked to the outer courtyard;

Liu Quankui, Ma Liang, Zhang Falin and other eight or nine skilled craftsmen who were here, after seeing him coming, hurriedly saluted and spoke.

"A few old brothers, you can make a price, how much salary do you need to do things for me?"

Although the parts of the generator are built separately by these people, I don't know what the use is?

But after repeated polishing, compared to others, he is finally an experienced veteran;

Liu Huayun was going to Jinan soon, but he didn't want to find people again, so he started to think about taking them for his own use.

"It's our honor to be able to do things for the master of the horses, just look at the reward for the money......"

The young man in front of him is not very old, but he is already a man of the year in the capital, who dares not to give him face; After the nine people looked at each other, one of them, a shrewd middle-aged man, took the lead in speaking.
