Qin asked

Ever since he made the telescope, Mu Mu was very interested in glass and light. Mo Dou knew that, but he didn't expect the other party to make a mirror directly. He thought he would make a microscope first...

Mo Dou thought for a while and asked, "You only used mercury and colored glaze?"

Shan shook his head, then took out his small notebook and handed it to Mo Dou: "I added some tin."

Mo Dou let go of the notebook, and found that the umbrella has actually tried many kinds of materials. The order of tin is not too high, and it is not too late. It is estimated that the umbrella himself did not expect to succeed so quickly. Only bronze can be made - you know, bronze is actually a copper-tin alloy.

In fact, tin was discovered and used very early in ancient times. In ancient China, tin was clearly mined around 700 BC, and it is said that people in Egypt, Mesopotamia, and the Indus Valley were around 3000 BC. Already using it, of course, only rumored.

Mo Dou looked at the mirror in his hand. Although the mercury-made mirror was still not as clear as the mirror made with silver mirror reaction, it still had advantages compared with the bronze mirror, at least it could still show some color.

"It's time to apply for a patent," Mo Dou nodded, then looked eagerly at his umbrella and wood, and added hesitantly, "Good job."

That's it?Umbrella and Mu Mu looked at each other, Mu Mu hesitated, and asked, "What's your opinion, Ah Dou?"

Opinion?Could it be that he is regarded as a mentor...

Looking at the two obediently standing in front of him, Mo Dou somehow had the illusion that a mentor led an intern to research a project...

Forget it... Mo Dou accepted this setting with some pain, and guided his two students with his 2000 years of historical experience: "The method of making a silver mirror has already been formed, and it only needs to be refined. Instead of It is time-consuming and labor-intensive to study this, it is better to think about other things.”

If you want to improve the mirror again, you have to use the silver mirror reaction mentioned in high school chemistry. Compared with the method of making mercury, the ink fountain is more familiar with this. However, there is no silver nitrate, no ammonia, and no sodium hydroxide. Glucose solution, the ink fountain is just done.

The two were a little confused, Mo Dou slowly guided them when he saw this: "Wu Mu, do you still remember the telescope?"

Mu Mu nodded, of course he remembered, he also remembered the triangular prism that can emit seven colors of light, and it was at that time that he became obsessed with the study of light.

Mo Dou was persuasive and persuasive: "Then have you thought about doing the opposite? For example...a microscope?"

Although it seems a bit whimsical, in the final analysis, the original microscope was a simple combination of two lenses, which has the same effect as a telescope.

Mu Mu slowly frowned, but the light in his eyes became brighter and brighter. He couldn't bear it anymore, and wished he could go back to the workshop to develop it immediately. Seeing this situation, Mo Dou let him go back directly: " If Mumu is fine, you can go back first, I still have something to say to Shan... By the way, remember to drink some goat milk when you go back."

After trying so many mirrors, I must have taken in a lot of heavy metals. Although mercury is chronic poisoning, it doesn't matter once in a while, but we still have to pay attention.

Mu Mu nodded, as if he wasn't surprised by the last order, and walked away directly, which made Mo Dou a little strange, but Shan told him: "Ah Qing has already told us."

No wonder, as a family of alchemists, it is impossible for them to be ignorant of the dangers of mercury.

Mo Dou closed the small notebook with the umbrella, touched the hairy cover on all sides, and asked, "Madam Qing also developed a mirror?"

"It's Ah Qing, not Mrs. Qing," Shan retorted, "I thought mercury could be used, so I asked Ah Qing to refine mercury."

"Okay, okay, it's Ah Qing," Mo Dou smiled, but then fell silent again, and he asked softly, "Does Shan like Ah Qing?"

Mo Dou's sudden question made Shan's eyes widen involuntarily, and he became nervous unconsciously. He raised his eyes and looked at Mo Dou secretly, like a child handing in his homework for the first time: "Master, what did you say about this..."

"Then let me ask you." Mo Dou was unusually serious, "Does Ah Qing like you?"

After a short silence, Shan exhaled, and he looked at Mo Dou calmly, as if he was just stating a fact: "Ah Qing likes refining medicine."

Shan's answer completely exceeded Mo Dou's expectations. He looked at Shan, and the other party seemed a little unwilling, but more relieved. Mo Dou had thought that Shan would let go, but never thought that Shan would let go so thoroughly, all at once. All the plans he had thought up before were overturned.

Mo Dou lowered his head and thought for a while, then handed back the book in his hand to Shan, and said, "Master, there is a formula here, how about you try it in seclusion for a few days?"

Seeing that Shan still wanted to say something, Mo Dou said forcefully, "You are the only one."

Shan was a little confused as to what kind of formula he was going to research and develop alone, as if shutting him up on purpose... But in the end, Shan chose to believe in Mo Dou, and carefully memorized the formula Mo Dou said in his mind.

……

When Ying Zheng came back with the medicine, Mo Dou was frowning in a daze. Ying Zheng stopped the attendant and took the pottery bowl. Seeing this, the attendant retreated with a wink.

Ying Zheng held the medicine in one hand, and pressed Mo Dou's waist with the other: "Still sore?"

Mo Dou shook his head, raised his head and saw the black medicine at a glance, and then his mouth twitched reflexively, thinking that he was given medicine by Ying Zheng twice, and both of them were fed one spoon at a time, it was almost fatal.

Thinking of this, Mo Dou quickly got up and stretched out his hand to grab the medicine, but was dodged by the quick-sighted Ying Zheng, who held the medicine bowl high and raised his eyebrows: "It seems that it is not sour gone."

Mo Dou was so angry that he couldn't speak. He swore that if Ying Zheng dared to hand the spoon to his mouth, he would definitely pour the whole bowl on Ying Zheng's face.

Seeing that Mo Dou was gone, Ying Zheng sat down, patiently cooled the medicine little by little, and then handed a spoon to Mo Dou's mouth...

"After drinking the medicine, let's go see Uncle Niu."

Ink fountain just about to lift the bowl: You won... I'll drink...

I don’t know if it’s Mo Dou’s illusion, but I always feel that the medicine this time is more bitter than usual (Jiang Yu, who prepared the antipyretic medicine for Mo Dou early in the morning: Ah, it seems that I accidentally added some Huang Lian with trembling hands... ...), Yingzheng is addicted to feeding, but Mo Dou is so bitter.

Seeing Mo Dou like this, Ying Zheng frowned, and wanted to kiss him, but Mo Dou pushed him away: "Don't... bitter..."

Regardless of Mo Dou's obstruction, Ying Zheng forcefully opened Mo Dou's jaw and invaded the other party's domain. The sense of touch is connected with the sense of taste, and the bitter taste is mixed with lingering entanglement and passed between the mouth and tongue, slowly flowing into the other party's friendship. Among the internal organs.

Ying Zheng let go of the ink fountain, and stuffed the candied fruit hidden in his bosom into the other's mouth: "Why is it so bitter, I won't feed it next time."

Mo Dou chewed the candied fruit, felt that the sour water finally stopped coming up, so he finally stopped, and he said vaguely: "How about feeding the porridge next time, Your Majesty?"

Ying Zheng nodded approvingly, and while helping Mo Dou stand up, he wondered whether he should talk to Jiang Yu, whether the medicine could not be so bitter, at worst, at worst, he would not take it a few times...

(Jiang Yu: Hehe.)

……

When Mo Dou saw Uncle Niu, he was sleeping. Healing the wound required a lot of energy. After all, Uncle Niu was old, so he was lethargic. Seeing this, Mo Dou finally breathed a sigh of relief.

The situation was much better than he thought. In this era when there was no tetanus vaccine, any wound could be fatal. Except that Uncle Niu recovered slowly due to his age, everything was fine.

Mo Dou supported Ying Zheng, and carefully exited the room so as not to disturb Uncle Niu.

"I will give Dou another butler," Ying Zheng thought for a while and said, "Uncle Niu probably needs to rest for a long time."

And even if he recovers, his energy will not be as good as before, and Mo Dou will have to deal with trivial matters by himself.

Seeing Mo Dou shaking his head, Ying Zheng hesitated and said, "Don't worry, this time...it's not eyeliner..."

Unexpectedly, Ying Zheng still cared about this matter, Mo Dou looked at Ying Zheng with some surprise, and Ying Zheng added: "I promise."

Mo Dou, who had long regarded Uncle Niu as an emergency button to call Ying Zheng, certainly would not care about this matter. He shook his head with a smile and said, "Don't worry, my lord, I won't need a housekeeper anymore."

Ying Zheng frowned and asked, "What do you mean?"

"I'm wondering if it's time to return Baidu Workshop to the king."

At the beginning, he asked for the workshop because he needed money for him to make things, but now everything is on the right track, and he himself has joined Yingzheng. The workshop is useless in his hands, so it is better to just use it Turn it over to the national research institute.
