"Yang Ding, why don't you get down to business?" Sun Yuying said angrily, looking at Yang Ding who was still giggling on the side.

"Yes, of course I will, Miss Sun, please give me a favor!"

Yang Ding smiled and placed the bottles and jars that had been prepared on the table. Yang Ding skillfully mixed tung oil into rapeseed oil and castor oil, then poured in the optimal proportion of ink and began to stir slowly.

.

Sun Yuying watched Yang Ding's operation attentively, with great interest in her heart. After seeing Yang Ding complete this familiar step, Sun Yuying asked: "Yang Ding, is it time to add rosin?"

Yang Ding smiled and said: "Don't worry, if you just add rosin like this, it will be impossible to fuse it."

With that said, Yang Ding took a tea bowl, crushed the rosin and put it in the tea bowl. Then he lit a candle, placed the tea bowl on the candle flame and slowly heated it.

Sun Yuying was very curious about this operation, so she watched carefully. In a moment, the rosin had melted into liquid liquid. At this time, Yang Ding picked up the tea bowl and slowly poured the liquid liquid inside.

A mixture of oil and ink.

Yang Ding poured it in slowly and stirred slowly at the same time. With the slow and even stirring, the ink and oil began to completely merge. Finally, with an incredible expression on Sun Yuying's face, the ink and oil were completely mixed.

fused together.

"Yang Ding, it's integrated, it's integrated!" Sun Yuying seemed to have suddenly forgotten her previous unhappiness, grabbing Yang Ding's arm and shouting happily.

"Yes, fused!" Yang Ding also breathed a long sigh of relief. This experiment finally did not disappoint him.

"Yang Ding, what's the principle?"

Yang Ding looked at Sun Yuying, who looked curious for knowledge, and suddenly understood that the awkwardness between him and Miss Sun during this period of time may be caused by the conflict between the cultures of the two eras.

Yang Ding tried to explain: "Yuying, this is called ink!"

"Ink? Yang Ding, what is ink? No, I should ask you why you want to study ink!"

Yang Dingdao: "Ink is a kind of ink mixed with pigments, solvents and connectors. The biggest feature of this ink is that it is water-resistant, and it does not scatter when exposed to water, which is the biggest secret of writing on water!"

Sun Yuying thought for a while and said: "Ink is a pigment and oil is a solvent, so rosin is the connecting material. The biggest feature of ink is that it tightly locks the ink in the oil, and oil is insoluble in water, so Bailian

The cult's spell of writing on water will be successful, Yang Ding, you are so smart!"

Yang Ding shook his head and said with a smile: "Yu Ying, it's not me who is smart, but ordinary people who work hard. Without the trees planted by our predecessors, where would we have a cool place to enjoy!"

"Yang Ding, are you saying that the ink has been available for a long time? But why didn't I know?"

Yang Dingdao: "Because we are short-sighted, Yuying, there are countless strange people and strange things in this world. If there is no ink, how could the White Lotus Saint create the evil method of writing on water? So I am sure that the ink already exists, but not yet.

It’s just popularized on a large scale!”

"Then, what industry would use this kind of ink?"

Yang Ding smiled and said: "Yu Ying, you are so smart, you must be able to think of it!"

"Yes---, is it wood printing?"

Yang Ding nodded and said: "Yu Ying, in fact, this kind of ink has appeared a long time ago. I think in some places these ink

Ink has been used in printing, and I believe that in the near future, our printing industry in the Ming Dynasty will undergo earth-shaking changes!"

The reason why Yang Ding dared to say this is because printing technology developed by leaps and bounds during the Ming Dynasty. For example, books, newspapers, advertisements, and letterheads that we are familiar with in later generations are all famous printed matter in the Ming Dynasty.

"Yang Ding, I seem to understand what you said!" Sun Yuying suddenly said in a daze.

"Oh? What did I say? What did I say?" Yang Ding was confused by Sun Yuying's lackluster sentence.

"You said that what you have learned is not suitable for the eight-legged essay and that you cannot pass the imperial examination. I didn't believe it at first, but now that I look at it, I already believe it!" Sun Yuying said a little disappointed.

Yang Ding said: "Yes, I was worried about how to explain to you before, but now it seems that it saves me a lot of words!"

Sun Yuying asked: "Yang Ding, besides how to make ink, what else do you know?"

Yang Ding frowned slightly, but this time Sun Yuying knocked him down. Yang Ding thought for a while, and suddenly took out a brand new goose feather from nowhere. Yang Ding dipped the hard tip of the goose feather into the freshly prepared goose feather.

Ink, write on the paper: "Learning for civilian use, learning from nature!"

These eight characters are as vigorous and powerful as flowing clouds and flowing water, and are the most formal regular script.

"Ah! Yang Ding, your calligraphy---!" Sun Yuying covered her mouth and exclaimed. These eight small regular characters were written extremely beautifully. Sun Yuying was also a talented woman who read poetry and books. She could tell from these eight characters at just one glance.

It can be seen that Yang Ding has worked hard on calligraphy for at least ten years!

Yang Ding smiled and said: "Don't be surprised, Yuying. When I travel, I always hold branches and sticks to write on the ground, so the hard pen is good. As for the brush, my writing is just like Yuying, you can see it!"

When Sun Yuying saw Yang Ding's open-minded smile, she felt a wave of regret. Whether it was civil studies or natural studies, or even this beautiful hard-pen calligraphy, they were not suitable for today's imperial examinations. She thought that a few days ago, she had complained about Yang Ding's incompetence.

She got angry when she was in school, but now that she thinks about it, she is really too willful.

"Mr. Yang, let's take the last step! See if the ink can float on the water!"

Sun Yuying felt a little disappointed and unknowingly changed her title to Young Master Yang.

Yang Ding didn't care. Although the imperial examination was orthodox in the Ming Dynasty, in the future, it would be the world of natural sciences such as mathematics, physics and chemistry after all!

Yang Ding nodded, picked up the commonly used tile before, and wrote a few words on it. After the writing was dry, Yang Ding slowly placed the tile in the water.

The water is still clear, and the ink marks are finally insoluble in the water, but the writing is still writing, because although the ink characters on the tiles are not dissolved in the water, they have also not fallen off and adhered to the water.

Yang Ding frowned slightly, wondering in his heart what went wrong?

Sun Yuying was not too disappointed this time. In her opinion, it was already very difficult to develop water-insoluble ink. Sun Yuying said: "Mr. Yang, the White Lotus Sect has been bewitching the people for hundreds of years since its establishment, so it must have its own unique methods.

Here, we have found the way to the White Lotus Evil Technique, and it must be not far away from being eradicated. Mr. Yang, don’t be discouraged, Yuying is willing to work with Mr. Yang to study how to make the ink characters float again!"

Yang Ding picked up the piece of tile and looked at it carefully for a moment, then gently touched it with his fingers.

text, suddenly his eyes were fixed on Sun Yuying's waist.

Sun Yuying's face turned red and she said: "Mr. Yang, why didn't Yuying see that Mr. Yang is such a dishonest person!"

Yang Ding withdrew his gaze with some embarrassment and said: "Miss Yuying, I am being rude. I wonder if I can show you the jade pendant around Miss Yuying's waist?"

"Ah? Jade pendant?" Sun Yuying lowered her head and looked at her waist. It turned out that Yang Ding was referring to the jade pendant that never left her waist!

Sun Yuying's face turned red and she asked, "What does Young Master Yang want with the jade pendant around Yuying's waist?"

Yang Ding didn't seem to notice Sun Yuying's unusual shyness, and continued to explain: "Miss Yuying, I suddenly discovered that the secret of the floating characters on the water may lie in the jade pendant around Miss Yuying's waist!"

Sun Yuying did not speak, but lowered her head, and finally reached out and took off the jade pendant from her waist.

The jade pendant around Sun Yuying's waist was first wrapped around her waist and then fell off. Yang Ding didn't know it at first. When Sun Yuying took off the jade pendant from her waist, Yang Ding discovered this.

Doesn’t he know Miss Yuying’s waist size?

In this era, a girl's waist size is very private. If this girl is not interested in you, how can she expose her secrets to others so easily? After figuring out the reason why Sun Yuying was so hesitant just now, Yang

Ding was a little hesitant to accept the jade pendant handed over by Sun Yuying.

"Take it, why are you still stunned!" Sun Yuying said angrily when she saw that Yang Ding suddenly became a little hesitant.

Yang Ding said "Oh" without any confidence, and reached out to take the jade pendant handed over by Sun Yuying, and then observed it carefully for a moment. The appearance of this jade pendant was smooth and gentle, and it was a piece of fine mutton-fat white jade!

Yang Ding secretly thought to himself. Sure enough, that night when he saw the white lotus sect's Hall Master Han writing on the boat on the boat, he subconsciously thought it was an ordinary piece of white porcelain because it was dark. After all, in Yang

White jade is very precious in Ding's heart, so Yang Ding never thought that it would be a white board polished with white jade!

Yang Ding picked up the brush, dipped some ink in it and wrote the word "yu" on the jade pendant. Then Yang Ding blew it. After the ink was completely dry, Yang Ding soaked the jade pendant in water!

This time, a magical scene occurred. After Yang Ding put the piece of mutton-fat white jade into the water, a moment later, the word "Yu" on it slowly broke away from the surface of the mutton-fat white jade. In the end, it turned out to be just like what Yang Ding had seen that night.

The ones that arrive are usually floating on the water!

"Yang Ding, it's successful! It's successful!" Sun Yuying grabbed Yang Ding's arm and shook it hard, feeling extremely happy in her heart!

At this time, Yang Ding truly breathed a sigh of relief. He thought to himself that if Yuying hadn't been reminded of this jade pendant today, he didn't know how long it would take him to figure out the mystery!

"Yang Ding, why does it not float when you write on tiles, but it floats when you write on jade?"

Yang Ding said: "Friction, this is because of friction. Yuying, although this tile looks smoother, it is of inferior quality after all. It still feels a bit rough, but your jade pendant is
