"Aya, what is this?"

"What does Xue Niang think it looks like?"

"Ivory."

The little hand held a round bead, pure white and with an excellent moist luster, very similar to ivory. It's just that the feel is far inferior to ivory, not to mention lighter, and it has a strange smell.

"It can do a lot of things, and it will be useful in the future."

"Has Aya done anything lately?"

Zhang Luoshui tilted his head and looked at Zhang De.

"I've been doing a little experiment recently, didn't your brother play with you?"

"He went to Master Cao's to listen to the class."

"Follow Li Shan?"

"Hmm."

"Then Aya will play with you, okay?"

"Okay."

There is a laboratory in Linzhangshan Academy, and the reception is still some distance away from the laboratory. Although there are certain dangers, it is much safer than the Hanyang Iron and Steel Plant.

Lao Zhang has recently started to get busy again because Dahe Workshop has discovered a special silver mine in Xihetao. In fact, the exploration team thought it was a gem mine at the time, but it was eventually confirmed to be a very small and strange silver mine. The silver ore is light yellow and yellow-green translucent, and has a strange smell that escapes after exposure.

After being sent to Wuhan, Lao Zhang judged that it was probably halide, most likely silver halide, and did a little experiment, and determined that it was an ore containing silver bromide.

The biggest advantage of this thing is to put it in the tortoiseshell glasses......

Of course, Lao Zhang didn't plan to add processing to tortoiseshell glasses, but planned to make some natural photosensitive materials to take a photo.

Before the illegal crossing, Lao Zhang, together with oil workers, had dealt with acetated fibers in some places. However, in this year, the acetated fiber has to be made. As soon as I gritted my teeth, I said that nitrocellulose should be easier, but I would come at every turn, and I would burp at thirty, which was a bit undrawable.

But at a certain moment, grass grew in my heart, and I thought that Lao Tzu hadn't taken a picture of his daughter......

Zi said: You don't know anything about photography.

Mencius said: SLR is poor for three generations......

The camphor distilled by Amway is mixed with nitrocellulose, which is enough.

It's no problem to make a table tennis ball, it's a colored table tennis ball, and it's good enough to exercise your children for three or five years.

When Lao Zhang pondered his spiral ascension to heaven or bibimbap, he probably didn't need to freeze his expression for a few minutes to take a photo.

It's still good to have the era of the Little Overlord learning machine, just take out a guy in the crotch of your pants, and you can shoot your beauty.

If you don't find silver bromide ore, forget it, since you have found it, don't make a fuss, Anu's white silk long legs, beautiful black and bright hair, Zheng Wan's choppy ...... Is it impossible to drift in the coffin?

It's a pity that there is no way to prepare it on a large scale, so it can only be made in the laboratory, but Lao Zhang estimates that it should be no problem to take a family photo.

Last year, Uncle Tan said that he would let Yan Liben's apprentices and grandchildren paint a very real portrait, probably preparing to die and leave it to future generations to admire.

It's a pity that several things in the test shoot are very mushy, only a rough outline, and Lao Zhang can only think about it first, as for how to solve this problem, he can only continue to experiment.

It's just that Rao is like this, after the outline of Hanyang City taken from Linzhang Mountain came out, it still made a group of girls in the house shocked.

Even Wu Shun and Bai Jie, who have always been soft-hearted, strongly asked their husbands to work overtime this time, and as for Lao Zhang's emphasis on the danger of the experiment exploding, they were all left behind.

Compared with "shoot my beauty", my husband is bloody, sweating, disabled and disabled, which is not the point at all.

"Sect Leader, want to go out?"

"Just walk around, you don't need a car."

"Yes."

With a wave of his hand, after Zhang De greeted the guards of his family, he led Zhang Luoshui to wander around the school. Because of the "autumn harvest", some children who work on the farm will return home to help the family at this time. So unlike other places, some schools in Wuhan have "autumn breaks" and some don't.

In addition to the students who are also busy with business, there are more "assault classes" and "literacy classes" for in-service personnel, mainly literacy, and the personnel are mainly "standout" from the front-line production activities. The importance of these people in production activities is quite high, and many "small inventions", "small creations" and "small improvements" in the production process are because they are more familiar with the production process, which makes it easier to think about it from the perspective of production convenience.

The job of the "engineering design dog" is consequentialism, as long as the goal can be achieved, this is success. As for how complicated, twisted, and easy to get started with the whole process, that's a matter for later.

A feedback on the product will lead to an improvement.

The coordination of the two requires the use of excellent management personnel, but because of the particularity of social reality, often the front-line production activities with "subjective initiative" of workers, their social status is too low, the right to speak does not exist at all, which leads to the efficiency of solving problems is not high.

This is not a problem that can be solved by system building, it is just a refraction and a projection of the social reality of the Zhenguan Dynasty, and it is impossible for Lao Zhang to engage in any kind of "combination of two participations, one change, and three combinations" in this year, even if it is just an "enterprise", the breeding of its "bureaucracy" does not need to be imitated or taught.

People instinctively and naturally learn to be "bureaucratic".

What Lao Zhang can do is only to "gild" some workers, brush a layer of gold dust here in Linzhang Mountain, and return to the factory, the work he does is still the same job, but because the literacy site is Linzhangshan Academy, then his voice will be a little louder.

Fake people are also "classmates" with some people, aren't they?

"Aya, Uncle Qin said that he often listened to Aya's fuqin when he was a child?"

Sitting on Zhang De's neck like a big horse, holding Zhang De's head with both hands, Zhang Luoshui leaned on it and asked curiously.

"Huaidao cried a lot when he was a child, Aye, I will play "Two Tigers", and Xue Niang can sing it."

"The servants all say that Aya is ruining the reputation of Master Lu......"

“……”

Why, "Mountains and Flowing Water" is not allowed "Two Tigers". Cultivating children's sentiments is also cultivating, which is clearly a kind of discrimination.

"Don't listen to their nonsense, they don't play the piano as well as Aya, besides, Ayah teaches you to sing a lot, Xue Niang, do you say it sounds good?"

"Sounds good."

"Don't sing it to them, this is the secret of Aya and Xue Niang."

"Hmm."

"When you get to the mountain pavilion in a while, can you hum "The Great Heaven" to Aye?"

"I won't hum ......"

"Hmph, Okay, Aye, I'll buy you candied mountain red."

"Can I ask for two skewers?"

“……”

The guards followed from afar, all of them were trained by Uncle Tan in Jiangyin's hometown, and from a distance, there was a younger one who sighed there: "The patriarch is really good to the snow lady, and Da Lang is not so favored here by the patriarch, let alone Erlang." ”

"Talking?"

The older man glanced at him, "Do your thing!" ”

Shrunk to the side to guard abruptly, the young guard stopped talking, but looked at Zhang De who asked Zhang Luoshui to ride a big horse on the steps, he still felt very surprised. When he was young, he felt that his patriarch was ruthless, and when he was young, his brothers could ignore it for several years, and his ancestors in the family could be transferred to the elders of the clan every year.

In the distance, the girl's strangely tuned humming sounded, and at this moment, a rider came from outside the school, and the knight dismounted, and went straight to the mountain pass.

"What's the matter?"

The chief of the guard asked the comer at the mountain crossing.

"The Hung State Army of North Korea Province has crossed the Whale Sea and landed in Fuso."

"Come with me to see the sect leader!"
