"Back to Your Highness, we have been acting in accordance with the standard experimental protocols, and we are all protected by asbestos clothes and hats before coming out of the pot, and no one is injured."

Zhu Linmiao nodded with satisfaction, being able to record the experimental parameters at any time, and operating in strict accordance with the experimental process, indicating that scientific experimental methods and scientific research norms have been deeply rooted in the hearts of these people.

As long as they have these basic qualities, without Zhu Linmiao's guidance, they will be able to rely on their own exploration to promote the scientific progress of the Ming Dynasty sooner or later.

In just one year, this progress alone is enough to go down in the history of the development of natural science in the Ming Dynasty.

When Mu Zhiqing saw His Royal Highness put into work, she pricked up her ears and listened to the few people next to her discussing the matter of vulcanizing rubber, and she couldn't help but be secretly surprised that the rubber was loaded on the wheels, and the car drove without bumps; made of shoes, even if you walk in a pond, you can not drip water; It is to take a piece at random and sew it on the sole, which can be non-slip and wear-resistant, and a pair of straw sandals can even be worn for two or three years without any problem.

A large number of transparent glassware are connected together with various tubes, some of which are grilled on the fire, and some are cooled in water. During this period, there were also many graduated instruments that she could not name, which should be used to measure something.

For a while, she only felt as if she had entered Penglai Wonderland.

In fact, these experimental equipment are extremely simple in Zhu Linmiao's opinion. Due to the lack of sealing rubber, coupled with the lack of polishing accuracy, the equipment is mostly sealed with oil sludge or wax, and some places are even wrapped in wet cloths, which is a sense of "black workshop" in later generations.

Everything is difficult at the beginning, it is these simple utensils that may well have given birth to the world's first vulcanized rubber.

Zhu Linmiao's side "searched" the memory of rubber in his brain according to the experimental record data.

Rubber is supposed to be a macromolecular organic, although the specific molecular formula is not remembered, but it is definitely a large polymer.

The vulcanization process is a process in which rubber molecules react with sulfur and cross-link to form a three-dimensional network structure. The rubber molecules, which were originally scattered, are pulled by the sulfur and become structurally strong.

That is to say, in vulcanized rubber, the rubber molecule and the sulfur atom correspond almost one-to-one, and the molecular weight of the former is certainly much larger than that of the latter. Then the ratio of rubber to sulfur should be very different.

It is likely that the proportion of sulfur was too large and the heating rate was too fast, which led to the sulfur injection.

He told Yao Qisheng his analysis, and arranged to reduce the amount of sulfur, adjust the furnace temperature, and so on. Afterwards, the test was restarted in several crucibles in a sulfur ratio of 3 to 20.

It was busy until it was close to dinner, and the problem of sulphur spraying was finally solved, and the process of vulcanization was proceeding slowly but steadily in several crucibles.

Mu Zhiqing watched the auxiliary king busy from the sidelines, and finally relaxed a little at this moment.

She suddenly thought that His Royal Highness had been busy with military affairs, that is, during the war, he had to preside over similar matters related to the development of rubber, and he was afraid that he would not have any leisure at all on weekdays.

With such hard work, how can people eat enough She thought that the smoke was about to rise over there in Qiantang, and it would be even more difficult for His Highness to go north to lead the troops at that time.

Thinking of this, she pulled Zhu Linmiao aside and whispered softly, "Your Highness, Zhiqing has often heard people say that Jiangsu and Zhejiang are the most prosperous and rich places in the world, but they have never been there before. I am fortunate to come this time, and His Royal Highness will take me on a tour of Shaoxing."

If she thought about it bluntly, if she asked Zhu Linmiao to relax, he would probably refuse, and had to say that he wanted to play, hoping that he would agree.

"Okay" Zhu Linmiao glanced at Yao Qisheng and the others, and whispered with a smile, "I'll throw the work to them, I've been in Zhejiang for so long, except for the military camp, I really haven't gone out for a walk." ”

He then instructed Yao Qisheng, and then went out of the east courtyard with Mu Zhiqing, and was about to go towards the gate of the mansion, when Mu Zhiqing feigned anger and said, "Your Highness, are you going out like this?"

Zhu Linmiao looked down and couldn't help but laugh dumbly, his clothes were smoky and stained with rubber marks, which was almost better than a beggar.

He went back to his dormitory, comparing several sets of clothes back and forth, and suddenly felt like he had a date in his previous life.

So he picked out a set of civilian clothes to change into, went out and winked at Mu Zhiqing and said, "Don't bring anyone else, just the two of us." ”

Mu Zhiqing immediately nodded happily, "Well, okay"

"Ahem"

There was a dry cough outside the house, and Zhu Linmiao remembered that Shi Lin had a pair of tailwind ears, so he had to push the door out with a bitter face, and said, "Okay, I'll take you alone, and stay away." ”

"My lord, this is too unsafe." Shi Lin frowned.

"I go in civilian clothes, and no one knows me." Zhu Linmiao deliberately straightened her face, "No matter how verbose you are, you won't even bring it." Oh, change your clothes and go. ”

"Yes"

When a little couple was just about to leave the north gate of King Lu's mansion, a few more people came over and took off their clothes to salute.

Zhu Linmiao looked at it, it was Mu Zhiqing's guard, Yale and the others, hurriedly reached out to help, and said in a low voice, "No need to be polite." ”

"Your Highness"

As soon as Yale said two words, he was interrupted by Shi Lin, "It's Childe." ”

"Yes. Childe is going to go"

Mu Zhiqing said first, "Just go, you don't have to follow." ”

"This, the master has ordered, Second Miss"

Shi Lin interrupted him again, "It's also a childe." ”

"Oh, if the second son has a mistake, the little one can't afford it."

Yale "bargained" for a long time, and Mu Zhiqing had no choice but to let him come with him, and he could only be alone.

The sun was scorching, and a group of four people walked slowly on the old street of Anchang, Shaoxing.

The streets are lined with shops and the sound of hawking is endless. At the end of each line, there are jugglers setting up stalls and performing on the stage, and although it is dinner time, the streets are still crowded.

Zhu Linmiao felt the unique prosperity and frolicness of the seventeenth century, and walked through the street with Mu Zhiqing's little hand, and before she knew it, all kinds of hard work in the past year disappeared, and even the air became lazy and sweet.

"Hey, what is that," Mu Zhiqing pointed to an elegantly decorated shop on the side of the street with her hand holding a windmill and a sugar gourd, "Childe, let's go and have a look." ”

"Hmm." Zhu Linmiao smiled and nodded, and walked into the store with her. He was all about Mu Zhiqing, but he didn't pay attention to the big words "Su Ji Zhenxing" on the plaque outside the store.

"This thing will turn on its own" The little girl stared at the boss with a pair of beautiful eyes, stuffed the windmill and sugar gourd to Zhu Linmiao, picked up the clockwork fan and looked up and down, "Shopkeeper, what kind of mechanism is this, can I take it apart and see?"

"Oh, childe, you want to buy it, and you will naturally dismantle it when you go back." The shopkeeper smiled and said, "But this thing is expensive, in case it is broken."

She held it to Zhu Linmiao again, "Princess, can you see why this thing is turning?"

The latter rubbed his nose in embarrassment, and before he could figure out what to say, the little girl happily pointed to another fan carved with orchids, "Why don't you buy one and go back"
