There are three kinds of new coins minted, all of which are about two millimeters thick and have diameters ranging from five centimeters, three centimeters to two centimeters, and naturally the face value of the three new coins ranges from fifty cents to ten cents to one penny.

The money of Wuwen is the largest, with a diameter of five centimeters, and the back is taken from Chang'an, the western capital of the Tang Dynasty, as the background, and the front is written in traditional characters of the Tang Dynasty, and the words 50 are written in Arabic numerals below, and the words Zhenguan 2nd year are below.

Like the fifty Wen new coin, the front of the ten Wen and the one penny, except for the different numbers, the others are exactly the same, only the back, the back of the ten Wen is the eastern capital Luoyang, and the back of the one is the northern capital Jinyang.

Zhao Chen actually wanted to suggest that Li Er's avatar be printed, but this idea was only flashed in his mind, and he immediately rejected it.

It is estimated that if his suggestion is really put forward, Li Er will have to call him to the Taiji Palace, and there will be a new duel, how can the dignified emperor's appearance be casually connected with such a copper-smelling thing.

There was jubilation in the money village, the minting of the new coin, not only Zhao Chen and Li Chengqian, but also the workers of the money village, this time also spent a lot of energy, and now, the new coin was finally minted, finally let their efforts during this period of time not in vain.

The person who gave Li Er the good news had already rushed to the palace as soon as the new coin was minted, after all, the matter of the new coin was related to the foundation of the Tang Dynasty, and Li Er had no reason to ignore such a major event.

Nowadays, the new coins minted are just rough embryos, and they have to be polished and nickel-plated. can be regarded as a real success.

A few workers, holding a new coin that had just been minted. Grinding excitedly, the rough edge of the rough embryo that was pressed out. Carefully polish the finish.

This is a cumbersome process, and there is no fully mechanized equipment, so it can only be polished manually.

Zhao Chen and Li Chengqian were not idle, just one batch came out, and at this time, they were busy making the second batch come out.

After the long rough embryo is pressed, it is then sent to the mold lathe here, and the two are closed in two times. One by one, the new coins appear in the mold.

In fact, once the material is successfully experimented, the speed of this lathe pressing is very fast, and batches of steel new coins, in the rumble of the lathe, are poured into the barrel next to it, and then handed over to those workers to polish and polish.

Several batches have been released in a row, and the success rate is as high as more than 90%. Looking at the mountains of new coins that were already in the workers' place, Zhao Chen finally settled down at this moment.

The last process that remains. It is to nickel-plate new coins, and only nickel-plated new coins can withstand the corrosion of time. Resist oxidation in the air, otherwise it would really be a pile of scrap metal.

Nickel plating is an important step in the oxidation resistance of all steels. This process is a process of dressing steel, and many steel products in later generations. There is a layer of nickel on it, such as lock handles, bicycle handlebars, and so on.

The nickel-plated pool has also been built a long time ago, and a boxy cement pool is paved with a layer of plastic steps.

Zhao Chen was going to the pool to mix the ingredients of nickel, when Li Er, who had just learned the news, walked into the backyard of Qianzhuang accompanied by the old eunuch.

walked leisurely and walked into the backyard, but Zhao Chen clearly saw the excitement in Li Er's eyes.

However, it can also be understood that the significance of the new coin is very great, not only because of the coins issued by Li Er as the new emperor, but also, because of the difference in materials, it can be regarded as creating a new precedent, with 'cheap' steel, as a currency circulation, it seems like a fantasy to think about.

In the backyard, it was already a mess, the workers who were originally polishing, and the workers who operated the lathe, at this moment, because of Li Er's arrival, threw away their work and saluted Li Er tremblingly

The workers who polish the new coins are just that, and those who can operate the lathe also directly throw away the lever, let the machine rumble, and the next moment, there will be a loud "boom" and fall down heavily.

The long rough embryo that had not been completely put into the mold just now was smashed into the sky all of a sudden, and in Zhao Chen's exclamation, it flew obliquely over Li Er's head, and suddenly plunged into the roof beam of Qian Zhuang, and the tail was still shaking vigorously, making a 'buzzing' tremor sound.

Zhao Chen's face was already pale with fright, and when he saw that Li Er was standing upright, his legs were weak, and he fell to the ground with a 'plop'.

Everything that happened just now was too fast, and it seemed very dangerous, Zhao Chen sat down on the ground, imagining the terrible scene just now, the whole person seemed to collapse, and his heart was beating vigorously.

Not only Zhao Chen, but also Li Chengqian was scared enough, just like Zhao Chen.

After seeing that Li Er was fine, his legs immediately became weak, and the whole person was like noodles, and he fell back softly all of a sudden, thanks to Li Er's anxious eyes, he grabbed Li Chengqian's arm at once, and lifted Li Chengqian up alive.

"One is my crown prince, and the other is my marquis!" Li Er helped Li Chengqian up, and said with a cold face: "It's really disappointing that such a trivial matter can be scared like this!" ”

Having said that, Li Er walked over, lifted Zhao Chen, who was sitting on the ground, lifted him up, patted Zhao Chen's shoulder vigorously, and immediately put his hands on his back, and said to the workers who were already crawling on the ground, trembling: "Get out of here!" ”

The workers in the yard were completely frightened at this time, especially the worker who was responsible for putting the long rough embryo into the mold, completely collapsed to the ground, and his body twitched slightly.

Hearing Li Er's words, the workers who were frightened and stupid got up in a large sound of thanksgiving, only the worker was still convulsed on the ground, Zhao Chen glanced at it, sighed helplessly in his heart, and had to arrange for someone to carry the worker out.

This unlucky guy was completely scared to pee, and it was estimated that he couldn't slow down at all every three or two days, so he arranged to carry the workers out, and when he turned around, he saw the old eunuch who came in with Li Er, standing upright, winking at Zhao Chen.

"Our legs are numb!" Zhao Chen walked over curiously, but he didn't expect that as soon as he walked to the old eunuch's side, he heard the old eunuch say a word to Zhao Chen in pain.

Fang Cai's scene was so dangerous that the old eunuch didn't even react at all. Thinking about that thrilling scene, the old eunuch was not directly scared to death. It's already quite good psychologically.

Li Er had already grabbed a few new coins and looked at them in his palm. Li Chengqian next to him explained with a pale face, Zhao Chen quickly found a chair for the old eunuch and put it behind his buttocks, and as soon as he put it down, the old eunuch sat down suddenly, making a loud noise.

Li Er, who was listening to Li Chengqian's explanation, heard the voice behind him, turned his head curiously, and pouted his lips with disdain after seeing the old eunuch sitting on the chair with a pale face. Fu turned around again and continued to listen to Li Chengqian's explanation.

"This is nickel water?" Li Er seemed to be interested in everything in the backyard, after reading the new coins, he looked at a few lathes, and finally picked up a stick, stirred it in the nickel water very roughly, and asked Zhao Chen without looking back.

Obviously, Li Er is a little difficult to understand, this looks a little black thing, how can these new coins be made. It turns into silver one by one.

Zhao Chen was too lazy to explain the chemical structure and reaction to Li Er, and it was estimated that Li Er might not remember it when he talked about it with a dry mouth. simply didn't talk about it, and directly made a batch of finished products in front of Li Er.

There are two types of nickel plating. One is electroless nickel plating and the other is electronickel plating. Compared with electroless nickel plating, Zhao Chen prefers electronickel plating. He doesn't lack anything now anyway.

In front of Li Er, the nickel water was prepared, and then the workers were instructed to pour all the polished new coins into the nickel water, and finally, the generator was lifted over to connect the current with the nickel pool.

"Let me come!" When the workers were instructed to start shaking the handle to generate electricity, Li Er, who was standing there with his hands on his back, suddenly stepped forward and asked the workers to step back, and under the surprised eyes of Zhao Chen and Li Chengqian, he personally went into battle.

When Zhao Chen saw Li Er's appearance, he was slightly stunned for a moment, and then followed Li Er's wish. Subsequently, Zhao Chen was responsible for the nickel in the nickel pool, and Li Er was responsible for Li Chengqian, sending electricity to the nickel pool.

In the originally calm nickel pool, at the moment when Li Er shook the handle, he began to react, and bubbles 'gurgled out' one after another, as if the water was boiling, and an unpleasant smell wafted out of the pool.

The mask was issued to Li Er a long time ago, and Li Er didn't wear it originally, but when the smell inside wafted out, there was no need for Zhao Chen to urge him again, Li Er obediently put on the mask himself.

Zhao Chen held a long leather stick, in the nickel pool, kept stirring, trying to push away all the coins stuck together, so that the nickel water was stained on it.

This is a physical job, the originally arranged worker is a guy with a big waist and a round waist, but unfortunately, now that Li Er is generating electricity, Zhao Chen is not good to let others do it.

It is estimated that it is useless for that guy to come up, the scene just now has explained everything, if something happens again at this time, it will not be a joke.

"We'll help you!" When the stirring was swaying, it was only a while, there was a layer of fine beads of sweat on the head, and just when the arm was sore, the voice of the old eunuch suddenly came from behind him, and then, the leather stick was taken by the old eunuch and stirred vigorously.

In this pool, there are all fifty coins, and the nickel water was added with polish by Zhao Chen, and with the nickel pool, it kept turning, and the new coins that occasionally came out of the water with sticks, revealing a silver-like light.

After another half an hour, Zhao Chen picked up the net bag that had been made a long time ago, stretched it out into the pool at will, salvaged a bag of new coins, and looked at the coins in his pocket, shining silver one by one, which made Li Er stop turning the handle.

This trip took more than an hour, during which Li Er was turning the handle alone, Li Chengqian was weaker, and when his middle arm was sore, he was directly taken by Li Er, and at this time, he was handing Li Er a handkerchief to wipe his sweat with a face of shame.

"Your Majesty!" The net pocket is full of silver new coins, which is completely different from the previous appearance, just this appearance, it is more than how many times stronger than Kaiyuan Tongbao.

Zhao Chen's heart was also happy, and when all the static electricity on the new coin was removed, he picked up a new coin and looked at Li Er and said.

"Not bad!" Li Er was also excited, dragging the silver new coins in his palms, turning them over and over, with an uncontrollable excitement in his eyes, and then, with a wave of his big hand, he said domineeringly: "I want all the new coins in this pool, and send them all to the palace!" ”

As soon as Li Er's words came out, Zhao Chen couldn't help but be slightly stunned, and then couldn't help laughing, and said: "Even if Your Majesty doesn't say it, the new coins in this pool will also be sent to Your Majesty, and the new coins minted by Your Majesty yourself will be used by people in the world, I'm afraid there are no yet!" ”

"I love to hear that!" Zhao Chen slapped a sycophant, which made Li Er open his mouth and laugh, and said to Zhao Chen. (To be continued.) )
