I am the cook, but I am Li Er's son-in-law

Copper coins can be faked.

After all, this kind of copper casting is easy to be mixed with some impurities, and after circulation, it is difficult to find out where it came from.

But money tickets are different. This kind of thing only comes from gambling houses, but the manufacturing process is extremely delicate, and each one even has an individual number.

The cost of counterfeiting is very high. At least some counterfeit banknotes that occasionally appear on the market are of inferior quality that can be seen with the naked eye.Even if you don't believe it, you can take it to the casino to verify it.

One-hundred-sentence sheet, one-score sheet, and ten-sentence sheet.

You can easily carry a lot in your pocket, if you can have so many.

This is already an excellent thing for ordinary people, not to mention for those foreign merchants-sometimes these things can also be used as amulets.

The horse bandits robbed copper coins, which they could use for themselves.

But these money tickets are no good. If they want to use them, they have to go to Chang'an.But they are all horse bandits, so how dare they go to Chang'an.

Moreover, the horse bandit didn't know whether these merchants would have anything to do with that Zhengyang Gong with these money tickets.If there is any connection and offends that high-ranking big shot, their lives will be lost.

On the other side of the court, they didn't pay much attention to the money ticket.

Even Li Shimin took the initiative to use it, he also disliked the burden of copper coins, how convenient these paper tickets are!
Think of it as prepaying a part of the copper coins at the restaurant in advance, and taking the voucher to exchange for food.

There are also officials who often come to restaurants to eat, but they haven't realized what kind of thing this is.

Someone bought wine.

This made other people suddenly realize, and they also took out money tickets one after another, or bought some drinks, or bought some snacks, and they always had to make up enough to cover the two costs.

Sooner or later, it will have to be spent, and now if you spend it, you can still get a small gift from Zhengyang Gong for free.

How could they be willing to let go of such a thing of taking advantage of nothing.

Liu Jingxian took the money ticket with a smile, counted it carefully, and then took out a few small puppets from under the counter and placed them on their table.

When the small objects were placed on the table, several guests were stunned.

What does the little gift look like?
Although they didn't expect any exquisite gifts, but this thing...isn't it a little bit unrelated to the train.

One person picked up a small doll and played with it in his hand.It's not a precious material, it's just the most common pine wood, and it doesn't weigh much in your hands.

The workmanship is very exquisite, the villain is cute, or holds a gong in his hand, or holds a drum in his arms. Yin Xuan originally wanted to make a chime bell.

But chime bells are ritual objects, and Yin Xuan can use them, but ordinary people are not qualified for this.Although the Tang royal family and the court may not necessarily take care of this matter, Yin Xuan thought, with his current status, it is not easy to be that person who eats crabs.

The guests take a closer look.

On the bottom of the villain, there is a line of words "Celebrate the opening of the Tang Dynasty train." Besides, what puzzled them most was the raised part of the villain's back.

Are you going to go realistic?These little people do look like men.

But... is this protruding part misplaced?How can it grow on the back.

Someone raised his finger and poked it. It wasn't fixed, but a little loose, as if... could be pressed down?
He hesitated for a moment, but pressed it anyway.The little puppet in his hand trembled suddenly, startling the man, and quickly put it on the table.

With a bang, the little puppet raised the mallet in its hand and hit the drum in its arms, making a muffled sound.

I moved by myself!

"what happened?"

The others were still studying their gadgets, and were taken aback by the sudden movement. They quickly looked up and saw the villain hitting the drum for the second time.

"How did you do that?" Someone's eyes lit up.

The villain moved, but the one in his hand didn't move.

The man took a deep breath, and there was some surprise in his eyes: "I just pressed the button on the back of it, and then it moved."

Several other people turned the doll over, saw the button on the back, tapped it lightly, and pressed it down.

With the beating of gongs and drums, there was a sound immediately.

There was a lot of noise at the dinner table.

In order to ensure that everyone can find the fun of this gadget, the batch of gadgets sent out by Wu Jue are all equipped with batteries.

She also tested that two batteries can support the little toy to run for a little more than four hours.

This time is enough for her to investigate and come up with a result.

"How... how did you do it?" A person was a little surprised, and fell off while grabbing the puppet, which still didn't affect it and continued to beat the gong, making a harsh sound.

He wondered how it was possible to do this.

Just push a button, and this thing works spontaneously?
Is it some kind of magical fairy method?

When the amount of knowledge is not enough, everything feels like a miracle.

Someone tilted his head, looked at the little puppet beating the drum in his hand, and suddenly said, "Do you remember an article published in a magazine by the ladies not long ago?"

Several people were taken aback.

They buy magazines regularly, but they have little academic knowledge, that is, they only picked them up during this period of time, and the previous notes are not very clear, let alone those higher-end academic papers.

The man continued to explain: "The article once mentioned a way to preserve electricity, which is to mix things like zinc, starch, batter, and toner together, and then wrap them in aluminum skin to store a certain amount of electricity. power..."

Speaking of this, he paused, and found a buckle on the villain's head. He opened the buckle, and when he opened it, the two batteries were shaken out, and at the same time, the movement of the puppet also stopped .

"It's this thing called a battery." The man held these two finger-sized things in his hand, and his eyes were a little surprised. "It turns out that electricity can not only emit light, but also have such a use?"

Someone shook his head: "Just for fun, nothing too practical..."

Before he finished speaking, someone came up to him: "What you said is wrong."

"Since it can drive the small wooden man, it can naturally drive the big wooden man."

"I haven't seen the science fiction in the last issue. It wrote about the magical function of batteries. It said that in the future, we can create a machine man and put a battery in it. This machine man can help plow the land and farm."

"Why is it useless?"

The person who thought it was useless slapped the table and sneered: "If it really had such a magical effect, Lord Zhengyang would have created it long ago. Are those people still needed to write ghost novels?"

Someone smoothed things over: "You can't say that, I remember that the topic seemed to be mentioned in that paper."

"Wait...let me see."
