Zou Qi's master is an idler in the mountains, so he naturally will not serve Li Chengqian, even if Li Er looks for him, he will not agree, with the same character as Yuan Tiangang.

Li Chengqian: "Who is your master?" ”

"I don't know if I said it, Your Highness, so it's better not to say it." Zou Qi said.

"Then why did he agree to your appointment in the Imperial Court?" Li Chengqian asked.

"When he was young, he didn't get in." Zou Qi said.

Li Chengqian: "??? ”

It's so real! Is it okay if you can't pass the test?

"When will you succeed him as the head of the Yin and Yang Family?" Li Chengqian asked.

"Just wait for him to die." Zou Qi said.

Li Chengqian nodded, it's okay, it's good to have hope.

"When will your master die?" Li Chengqian asked.

"Negative sentiment from Zou Qi, +159"

"He's in good health!" Zou Qi said.

Li Chengqian: "......"

"Your Highness, I'll go back first, there are still things to do." Zou Qi said.

Li Chengqian asked curiously: "Zou Qi, what do you think the sun and moon are like?" ”

"The sun is the source of all things, and the moon only reflects its light." Zou Qi said.

Li Chengqian was surprised: "Why didn't you tell everyone about this?" ”

Zou Qi: "Isn't it a cool thing that I know about it myself, and others don't know?" ”

Li Chengqian: "......"

No wonder science has not been able to develop, that is, many people are Zou Qi's thoughts.

"Alright, you go get busy, I'll get you an astronomical telescope when I have time." Li Chengqian said.

Zou Qi was surprised, astronomical telescope? Sounds amazing.

The next day, the newly arrived express almost made Li Chengqian fall to the ground, and it was actually a stack of advertisements.

Very ordinary sales advertisements, the things on it, are also some things that can often be seen on the advertisement.

It's boring! Li Chengqian couldn't help but sigh.

These papers are tougher and stronger than today's paper, but paper is paper, what else can be so powerful?

Li Chengqian thought about it, such a hard paper, stacking airplanes is a very good choice.

He quickly folded a paper airplane, then two, three......

A whole bunch of paper airplanes!

Arriving at the door, he began to release the planes, which passed through the high sunflowers, dug less than half of the potatoes, and finally, came to the outside of the field.

It flew quite far, this distance surprised everyone, what is this?

"Which of you would like to give it a try?" Li Chengqian asked.

No one dared to answer, for fear that Li Chengqian would rectify them.

"Xiao Ningzi, it seems that you still have to do this matter." Li Chengqian said.

Xiao Ningzi had to come up hard.

He picked up a paper airplane and looked at the calligraphy and paintings on it, a little puzzled.

"Your Highness, what is this magical thing?" Xiao Ningzi asked.

"It's called a paper airplane, and it's made of paper." Li Chengqian said.

"Made of paper?" Xiao Ningzi said.

"Yes."

"Negative sentiment from Xiao Ningzi, +129"

How can this be paper? The paper is not so strong.

He tried to fly, but he really flew out, but not as far as Li Chengqian flew.

Li Chengqian said: "It's fun, right? ”

Xiao Ningzi nodded.

"Fly the rest out." Li Chengqian said.

Xiao Ningzi flew one after another, and he was very happy to fly.

"Your Royal Highness the Prince, this paper airplane is so fun, I have never played such a fun thing!" Xiao Ningzi said.

Everyone was extremely envious, and Xiaocui was also looking at the paper airplanes flying out one by one, and she wanted to try it.

No, Xiao Ningzi flew all the paper airplanes out.

"Fun, right?" Li Chengqian asked again.

"It's fun!" Xiao Ningzi said.

Li Chengqian: "Okay, you can pick up all the paper airplanes that flew out." ”

Xiao Ningzi: "??? ”

"Negative sentiment from Xiao Ningzi, +188"

He was very happy, but now, only regret remains, some paper airplanes, he even flew to the roof, how can he get them back?

"Don't ask for help." Li Chengqian added.

Xiao Ningzi wants to cry without tears, it's so miserable!

He could only pick them up one by one, and the ones on the roof could only be climbed up by ladder.

"Your Highness, the order for our cemetery and Tomson has been greatly reduced." Lu Zihou said.

Li Chengqian: "This is natural, if you want to buy it, you will buy it a long time ago, and if you can't buy it, you won't buy it." ”

"I'm afraid we won't be able to recover our costs!" Lu Zihou said.

"How much will you lose?" Li Chengqian asked.

"300,000 times." Lu Zihou said.

"Huh?"

Li Chengqian instantly refreshed, 300,000 yuan, this is not a small amount!

If so much is lost, so much time and effort will be in vain.

"Let's make some flyers and distribute them on the street every day, and after they are distributed, it should increase sales." Li Chengqian said.

"Flyers?"

Li Chengqian explained, and Lu Zihou was shocked: "What a good idea!" ”

By the way, Li Chengqian told Lu Zihou about the idea of movable type printing.

Lu Zihou: "??? ”

If a flyer is a good business idea, then movable type printing is a peerless invention!

"His Royal Highness the Prince, this movable type printing technique is very powerful." Lu Zihou said.

Li Chengqian: "Actually, it's just to make it easier to print leaflets. ”

Soon, the leaflets were printed, not by movable type printing, but by woodblock printing.

Movable type is still in the works.

Soon, the first people on the street to hand out leaflets were all small children, making a little money.

Everyone loves children, the flyer went smoothly, and the people who knew about it were surprised, this method is really good!

So, some people began to follow suit.

To imitate nature is to imitate completely, and businessmen began to study the advertising slogans on the flyers.

"Classic design, reasonable price, Lanling Cemetery, your best choice."

"Lake view, green ecology, park, art education, center, Tomson Yipin, give you exclusive enjoyment!"

These statements are very novel, and many businesses have begun to design their own advertising slogans.

As a result, in Chang'an City, leaflets have become a new trend, and large merchants have leaflets sent out.

Naturally, everyone is very happy, and now, when I go to the thatched house, I finally have comfortable paper to use, which is a good thing.

The first movable type printing plate was produced, and Yan Lide held it and continued to admire.

"Why didn't I think of such a simple design? His Royal Highness the Crown Prince is really a genius! Yan Lide said.

"My lord, do you want to take this thing for the saint?" The principal asked.

"Yes, hurry up and take it, the saint will definitely be happy to see it." Yan Lide said.

The first movable type printing plate was sent to Li Er.

Li Er held a small movable type printing board and fiddled with it curiously.

Different words, combined together, become one sentence, and then combined, another sentence.

"Gao Ming's invention is quite interesting!" Li Erdao.

In fact, this one for Li Er is a model, which is naturally very fun, and the real movable type printing board is not so fun.
