How profitable the lottery is, is not something that people in this world can imagine.

It's like a robbery!

But due to technical limitations,Today Zhou An research lottery encountered a lot of problems,And the biggest problem,Is anti-counterfeiting! Once the lottery ticket can be forged, the casino goes bankrupt in minutes.

And Zhou An is not just to issue lottery tickets in Qianjing, but to promote the entire Dongqian.

The circulation will be huge, and the issue of anti-counterfeiting is a top priority.

In this regard, Zhou An's first thought of using carbon paper, that is, the kind of black and blue paper sandwiched between the first page and the second page, what is written on the first page, the second page will leave the same font, which can be said to be the simplest and most direct way to ensure that the bill is difficult to be forged.

But there are two problems with using carbon paper.

One is the problem of the pen, the brush is not enough pressure on the paper to leave the font on the second page, and he has to invent a new pen.

Rather...... There is no carbon paper.

There is no such thing as carbon paper in Dongqian! Zhou An also had to invent carbon paper.

Because he wanted the results today, he had to give up the method of using carbon paper to prevent counterfeiting.

After studying for a long time,He finally chose to use the home page to prevent counterfeiting,The home page has the same number,As long as you fill in the same lottery purchase information,The home page is given to the buyer,The page is kept as a stub,So that you can basically eliminate forgery.

Sooner or later, this anti-counterfeiting will have to be improved.

As far as this world is concerned, the most high-end anti-counterfeiting technology is naturally the anti-counterfeiting technology used on the silver and gold tickets, and the horror is that the top anti-counterfeiting technology of silver tickets is not in the imperial court.

And in the Tongbao number.

Even the silver tickets issued by the imperial court in the early years of the founding of the People's Republic of China, the technology used came from Tongbao.

Zhou An also plans to use this technology on his own lottery tickets.

But it can't be done for a while.,Especially if he wants to promote the lottery to the whole country.,It's just a multi-set of color printing molds,How long can it be made,It's hard to say.

For the time being, this can only be the case.

Zhou An gave Ma San a small book, called "Lottery Details".

Let Ma San understand what a lottery is, there are a lot of lottery games, and even develop instant lottery tickets, Zhou An wrote these in the "Lottery Details", let Ma San study.

In fact, these gambling equipment invented by Zhou An are very rough.

He just let Ma San understand what these gambling equipment were.

After that, it depends on Ma San's ability, and I don't know how long it will take to mass produce it, not only to make it, but also to make it look good, and to make a high-end atmosphere on the grade, to have a card.

"Ask someone to carry it away, let's go back to the palace first."

"Congratulations to the factory."

******

Back in the palace, Zhou An didn't go back to Ning'an Yuan this time, because the spirit pupil had already started, and he could at least use the spirit pupil for gambling, which was enough. After being embarrassed with the empress for several days, Zhou An thought that he had to comfort her tonight.

In the courtyard of the dormitory.

Zhou An habitually retreated from the eunuchs and palace maids who guarded the door.

The lights have been turned off in the dormitory.

The empress didn't wait for Zhou An anymore, because she knew that Zhou An would not come.

Zhou An walked up the steps, listened to the movement first, there was no sound in the dormitory, he pushed open the door of the dormitory without making a sound, went in sideways, and closed the door again.

There really wasn't any movement at all.

Even if the empress is Tiangang, she can't detect it.

Standing at the door of the dormitory, Zhou An was just about to walk in, when he heard some strange sounds, which seemed to come from the dragon bed, very light, and intermittent, this small voice Zhou An couldn't really hear it outside the door, and he heard it clearly when he came in.

There is no one for the empress.

Why?

There were curtains hanging around the dragon bed, and Zhou An couldn't see the situation on the dragon bed, but now he had a way to see it.

Gaze condensed!

Attentively!

The eyes were slowly bloodshot, and only a little bloodshot appeared, and the curtain began to become transparent in Zhou An's eyes, but because the night was too dark and the light in the dormitory was insufficient, Zhou An had to exert a little more force to see through the curtain thoroughly.

He saw the empress and Kou Dong'er.

The empress leaned on Kou Dong'er's arms, tilted her head, and was actually ...... Dear Kou Dong'er!

Zhou An faintly felt that there was something more on his head, and it seemed to be a green light......

The empress is really kissing Kou Dong'er.

The kind of kiss.

kissed for a long, long time, and there was no other action, just kissing...... Zhou An stood for half an hour, watching all the time, because the power of the divine soul was overconsumed, and his brain was already a little black.

What is there to kiss between two women?

Zhou An thought that before this, many days ago, he felt that the empress's kissing skills had improved, and when he kissed for the first time, the empress was very clumsy, and then it was as if she had no teacher, and she was very skilled.

At that time, Zhou An suspected that the empress might have practiced.

But he didn't expect that the empress would practice like this.

Poor Kou Dong'er was so toyed with by the perverted empress.

Zhou An decided to criticize it!

The time was almost midnight, and the empress said something in Kou Dong'er's ear, but Zhou An didn't hear it clearly, and then she didn't kiss, and the empress buried her head in Kou Dong'er's arms, as if she was going to sleep.

There is nothing more to criticize.

Zhou An rubbed his eyes, and gently hooked his hand back, squeaking...... Click.

The door of the dormitory opened a crack and closed again.

Zhou installed as if he had just come in.

The empress on the dragon bed raised her head suddenly, glanced at Kou Dong'er again, and then said with a calm face: "But Xiao Anzi? ”

"Yes, the minister." Zhou An replied and walked in quickly.

Kou Dong'er had already gotten up, pulled out the curtain and got out of bed, and went to light the candle by the window.

Zhou An walked to the dragon bed, and saw the empress looking at him with a lazy posture and unhappy eyes, so he said: "Holy Lord, the minister has just finished busy, and the matter of the casino is estimated to be open in a while......

Zhou An was purely speechless, and he was also diverting the empress's attention.

"Xiao Anzi, you really want to earn 100 million taels in three months......" The empress was a little yin and yang, and sure enough, she liked this topic.

"The minister has faith." Zhou An smiled.

"Humph!" The empress snorted lightly, and did not continue to entangle with Zhou An on this topic.

Zhou An glanced at Kou Dong'er and motioned for Kou Dong'er to go out.

At this moment, the empress's voice came faintly: "Dong'er, serve Xiao Anzi's wide clothes......"

"Yes!" Kou Dong'er received the order, and his little hand climbed onto Zhou An's shoulder from behind.

Zhou An raised his eyebrows, what trick is this empress going to play?

It doesn't matter!

Because he knew the empress's great conspiracy, Zhou An was fearless and could accept anything calmly.

Kou Dong'er gave Zhou An a wide coat, hung up the Jiaolong robe, and helped Zhou An take off and put away the boots.

"I'm tired of Sister Dong'er." Zhou An, who was only wearing obscene clothes, said and climbed onto the empress's dragon bed.

"Dong'er, you also come up and sleep on the right side...... Xiao Anzi, you sleep on the left. The empress said again.

Zhou An's movements froze.

Three people?!

Sleep together?!!
