It turned out that since Lu Ning took charge of the Daming Academy of Sciences, he began to work on the development and research of Daming banknote paper, fortunately, he signed in to obtain the manufacturing technology of banknotes from various countries in later generations.

He adopted the most advanced technology, doping the banknotes with many fibers such as silk, so that the banknotes were not easily destroyed even if they were soaked in water.

Mr. Liu followed him to the Daming Academy of Sciences, and couldn't wait to ask him for new anti-counterfeiting technology.

Lu Ning smiled and said.

"Don't be impatient, old gentleman, I'll print you a sample ticket with the same denomination, and you'll know it after you read it."

As he spoke, he ordered several doctors from the Academy of Sciences to go down to prepare, and about an hour later, one of the doctors took a check and handed it to Liu Xingwu.

The old gentleman took it and took a look, only to see that this money was thicker than the original Ming jewelry banknote, and the feel was still a little concave, and there was a portrait of Zhu Yuanzhang in court clothes printed in the middle of the treasure banknote, and there was a capital "Yiguan" word next to it.

And the top is marked with the following words: Daming Treasure Money Bureau, counterfeiters of treasure money, full of copying.

Below are the encrypted characters that Liu Xingwu researched, which contain the denomination of the coin, the date of production, the production site, and the number of the locker where the copper coin is locked.

When he touched the pearls on the crown that Zhu Yuanzhang brought, he suddenly found that the beads on it were actually concave, which shows that the technique adopted is extraordinary.

Now the printing technology of the Treasure Banknote Bureau cannot achieve this effect, Liu Xingwu nodded.

"His Royal Highness's papermaking technology is breathtaking, especially this special printing technology, which is even more amazing, but there is no other specialty, and ordinary people still can't recognize it."

Lu Ning smiled and ordered, "Bring our newly invented money detector lamp." ”

At this time, someone took something the thickness of a finger, and after turning on the switch, a purple light was emitted, shining on the blank surface of the treasure banknote, and suddenly a fluorescent word appeared.

It is the word "Yiguan" in capital letters.

"This ...... It's amazing, how exactly do you do it? ”

Lu Ning smiled slightly and said.

"This is the purple light anti-counterfeiting technology, and this kind of purple light lamp has now been produced in thousands, as long as it is distributed to many business offices under the Daming Bank, it can be checked at any time."

Liu Xingwu nodded and said in admiration.

"Wonderful! It's even more subtle than the cryptographic words we use now, and you're amazing. ”

Lu Ning nodded with a smile and said.

"So sir, this set of ciphers invented by you is the primary encryption, in the event of an accident, the primary encryption leaks, at least there is a secondary encryption to protect it."

Liu Xingwu nodded and said.

"Your Highness, according to what you said, are these papers still handed over to the processing factory in Wu County to make?"

Lu Ning's eyes were solemn, and he sighed and said.

"I suspect that there is a mole in the processing plant, but it still hasn't been dug out, so we can't startle the snake first, we will directly send these special papers to them, and then when the last process is completed, add purple light anti-counterfeiting technology, but don't leak it out at the last time, and see what will happen outside."

Zhu Xiongying, Liu Xingwu and Lu Ning and other relevant personnel have signed confidentiality agreements, and only these few people know about Ziguang encryption.

Then all of these people, except for Zhu Xiongying, lived in the Daming Academy of Sciences.

And Zhu Xiongying pressed these wallpapers to Wu County, handed them over to Zhu Shouzheng, the director of the Treasure Banknote Bureau, and ordered him to quickly print new banknotes, and then hand them over to Daming Bank for issuance, and quickly exchange the original banknotes.

On this day, in a secret room, two masked men were talking in secret.

One of the men wearing a bear mask said to another man wearing a fox mask.

"Fox, now that they have adopted a new type of currency, we have no way to make money, can you get this new type of coinage paper?"

The fox seemed a little hesitant: "These paper Daming Academy of Sciences have been planned quite carefully, if there is one less can be seen, this is a crime full of beheading." ”

"Do they use all these banknotes?" The bear asked.

"That's not true, it's said to arrive in three batches, and it should be possible to start here."

Bear suddenly made up his mind and said.

"If you encounter a thief in the process of transportation, and you get out of the basket, it should be someone from the Daming Academy to carry it, and the board can't hit you and my brothers."

The fox said hatefully.

"It's not difficult to get this, the difficult thing is that the set of passwords is in charge of the old man Liu Xingwu, this old man doesn't eat soft and hard, oil and salt don't enter, for people like him, he just wants to eat turtles and has nowhere to eat."

The bear sneered and continued.

"Although the turtle is patient, he always sticks out his head sometimes, as long as he finds a suitable time to catch his outstretched head, he can't help but give in."

The fox looked at the bear and asked.

"I don't know anyone in the East Palace, do you have a way?"

Bear laughed and said.

"Liu Xingwu's son is now the prince's companion, but this kid is not like him at all, he spends a lot of money, and he likes to do big health care, do you know what weapon to use against him?"

The fox smiled mysteriously and said.

"That's natural, if you have money, you can use a grinding ghost, it's the same for everyone."

On this day, Liu Jing, the son of Liu Xingwu, returned to his mansion, and suddenly found that his father, who often chatted with him, was not at home, but there was an invitation in the ear clip.

"Recently, there is one more Qingqi person in the Ruyi room, singing, singing, dancing, blowing, playing and playing are all connected, and now I am looking for celebrities all over the world to comb her, and I have heard that my brother's talent is the best in Jinling, do you want to try it?"
