After reading the heart milk ball, the cannon fodder family went crazy

The words "lithography" suddenly exploded in the minds of Su Zhaozhao and Su Dahe like thunder on the ground.

It took a while before Su Dahe found his voice.

"Aping, are you saying that lithography is used to print books?"

Su Shaoping nodded hurriedly, unable to stop the smile on his face, "Not only can you print books, but you can also print paintings."

Su Dahe looked confused. He really couldn't figure out how to use printing technology to print pictures.

Su Shaoping was not in a hurry to explain, but said: "Third uncle, you will know for yourself when you go and see for yourself."

With that said, Su Shaoping picked up Su Zhaozhao and walked towards his studio.

Su Dahe followed closely. After taking two steps, he remembered that he was still teaching a few children, so he stopped to let Su Shaoan and the others move freely.

This made several children so happy that they quickly disappeared after losing their decadence in class.

As for lithography, I don’t understand!

Is it fun to play?
studio.

Su Shaoping took out a square stone about the same size as paper and placed it on the table. Then he took out a piece of paper about the same size and covered it. Then he pointed to a box of ink on the table and said: "Uncle Third, you Use this ink to write a poem on paper.”

Su Dahe didn't know why, but he didn't ask anything. Instead, he picked up a pen, dipped it in ink, and wrote the full text of Li Bai's "After the chaos and separation, Tianenliu Yelang recalled the old travels and presented it to Jiangxia Wei Prefect Liangzai".

After he finished writing and passed half the incense stick, Su Shaoping uncovered the paper on the stone, then took out a box of ink and a small brush, dipped the small brush in ink, and applied it evenly on the stone.

After waiting a few more minutes, he pressed the stone against the clean, wordless paper for a few seconds.

After he took the stone away, Su Dahe was shocked to find that the poem he wrote had been copied completely onto the paper without any errors.

Seeing the shock on Su Dahe's face, Su Shaoping said proudly: "Uncle Third, this is just the beginning, don't blink."

Su Shaoping repainted the stone with ink, and then printed a complete poem again. After repeating it back and forth more than a dozen times, Su Dahe went from the initial shock to numbness.

Seeing Su Shaoping who wanted to continue copying, Su Dahe quickly stopped him.

"That's enough, Aping, how many times can you... this stone be copied?"

Su Dahe looked at the stone in his hand and couldn't figure out the principle after looking at it for a long time.

"It should be able to be copied hundreds of times...probably, maybe, maybe..." Su Shaoping looked uncertain, and then he quickly added: "If the third uncle feels it is not enough, I will find a way to improve it."

"Enough, enough!" Su Dahe said quickly.

According to his understanding, whether it is movable type printing or engraving printing, the characters need to be made in advance before printing.

However, Su Shaoping's lithographic printing technique only requires one handwriting to print. This efficiency is beyond description in words.

Just like ancient people drilled wood to make fire, but now people only need flint to make fire.

Pure dimensionality reduction attack, there is no comparison.

Su Shaoping looked at it for a long time and found that the core of lithographic printing was not on the stone, but on the original paper and ink.

Seeing that Su Dahe had figured out the secret, Su Shaoping also hid it, took the paper and ink and explained: "This paper and ink are specially made, based on the principle that stone absorbs ink and oil and water are incompatible..."

Su Dahe was confused. He understood that oil and water were incompatible, but what about fatty medicinal ink, acid-containing glue, acidified water-repellent ink and colorless, unacidified water-repellent ink and color? , no one said a word.

Su Dahe, a scumbag in science and engineering: Thank God for allowing Chu State to ignore liberal arts and science! (bushi)

At the same time, Su Zhaozhao listened with great interest.

[I didn’t expect that my eldest brother would actually develop lithography. Counting the time, it was more than a hundred years earlier than Senna Field]

[The eldest brother is Sue Sunnerfield from Chu State, the genius among geniuses, awesome! 】 Su Zhaozhao made one rainbow fart after another, while Su Shaoping looked guilty.

If he guessed correctly, the method he used was developed by Sunner Field.

[Tsk, tsk, tsk, eldest brother is simply a natural saint of science and engineering. If he was born in modern times, he would not be able to kill indiscriminately]

Su Shaoping: Thank you for the invitation. You don’t need to be in modern times. Now you can walk sideways (cross out) all over the world!
Su Dahe brought new paper and covered it on the stone. After looking at Su Zhaozhao, he quickly sketched on the paper.

After a while, he used the same method to print out Su Zhaozhao's portrait.

"Wow, Third Uncle, you painted me!" Su Zhaozhao said in surprise.

Su Shaoping took a look and was shocked: "It really looks like Zhao Zhao. It's the first time I've seen such a portrait!"

"Of course it looks like it." Su Zhaozhao raised his head proudly, "This is the sketch and realistic painting I taught my third uncle."

Su Shaoping was amused, touched Su Zhaozhao's head and said, "Yes, yes, our Zhaozhao is still great."

Looking at the sketches on the table, Su Zhaozhao suddenly felt inspired.

"Brother, do you think that if my third uncle could draw our family and print it out using lithography, wouldn't we have a family photo?"

Su Shaoping's eyes lit up when he heard that, yes, why didn't he think of this?
In an instant, the two of them blinked and looked at Su Dahe.

"Third uncle~"

Su Dahe waved away the two cute attacks, coughed slightly and said, "I'll talk about it when I'm free."

"Long live Third Uncle!" Su Zhaozhao raised his hands and shouted excitedly.

Hearing this, Su Dahe's expression changed, he quickly covered Su Zhaozhao's mouth, and then winked at Su Shaoping.

Su Shaoping turned around with a solemn expression and walked outside to look around. After finding nothing unusual, he returned to the house and nodded to Su Dahe.

Su Dahe breathed a sigh of relief and let go of Su Zhaozhao.

Su Zhaozhao blinked and asked with a puzzled look on his face: "What's wrong with Third Uncle?"

"Zhaozhao, those two words just now are not allowed to be spoken again. Do you understand?"

"What are you talking about?" Su Zhaozhao looked confused, "Long live?"

"You naughty kid!" Su Dahe was so anxious that he covered her mouth again, "Don't say these two words again, otherwise our whole family will be in danger, do you understand?"

Su Zhaozhao didn't know why at first, but then when he thought that this was a feudal dynasty, he suddenly broke into a cold sweat and nodded hurriedly.

Seeing the fear on Su Zhaozhao's face, Su Dahe was afraid of scaring her, so he let her go and said softly: "Zhaozhao, trouble comes from the mouth. Third uncle knows that you understand. In the future, you must be careful not to follow the truth. "

"Third uncle, I remember." Su Zhaozhao said babously.

Su Dahe nodded, then changed the topic and said: "Aping, you should keep the matter of lithography a secret for the time being and don't let outsiders know."

"I understand, Third Uncle, lithographic printing was originally made for you. Just take it for whatever you want." Su Shaoping said nonchalantly.

Su Dahe looked touched and said with a choked voice: "Aping, third uncle owes you a favor this time."

It wasn't that he didn't want Su Shaoping to use lithography to dedicate it to Emperor Ming to claim credit, but now lithography had a more important role in his hands.

Thinking of what he had to do next, Su Dahe's heart felt hot.

Just as he was thinking about it, Su Dahe suddenly discovered a fatal problem.
