When Zhang Sijiu finished talking to Yang Yuanding for the third time about the process of making penicillin by the soil method, Yang Yuanding was still in a trance: "You call this simple?" ”

Is this called simplicity?

Shouldn't that be called difficult to climb to heaven?

There are so many steps, as long as one step goes wrong, then it is equivalent to failure!

He counted with his fingers: "One, two, three, four...... Sixteen! Sixteen steps! It's not easy! First of all, containers are not good! ”

Yang Yuanding's face was hideous and twitched: "Otherwise, I'd better go and study glass first." ”

His father has two glass vases, and his mother has several glass dishes and hairpins.

Zhang Sijiu shook his head: "No, no, glass is too expensive these days, let's just use clay pots." Studying glass is too time-consuming. ”

Besides, she remembered one method of making nurturbin penicillin, and the others couldn't.

"Let's work out, once it is put into production, the profit will be seven or three, how about it? It's up to me to promote to patients. Zhang Sijiu saw that Yang Yuanding wanted to retreat a little, so he immediately threw out the best temptation method in the world: the Dafa of painting cakes!

As long as the pie painted is big enough, there has been no one who has not been fooled for so long!

Zhang Sijiu's voice was soft: "You know the effect of antibiotics." Even if we sell it to the powerful in the future, they will use it in the army, and it will be a lot of income. Not to mention that it is widely used in various diseases. With such a big market, it's still an exclusive secret recipe, and others can't figure it out if they want to! ”

Even if Yang Yuanding doesn't love money anymore, it will be heartwarming every minute.

But reason still struggled to suppress the impulsiveness in his heart, and he couldn't cry or laugh: "Si Jiu, do you think we can study it?" The exclusive market is the exclusive market, and the exclusive secret recipe is the exclusive secret recipe, but if you can't get it, it's also in vain. ”

Zhang Sijiu pondered for a moment and used a famous old saying: "Dripping stones wear." ”

"As long as the kung fu is deep, the iron pestle can also be sharpened into a needle?" Yang Yuanding sighed deeply: "I remembered a sentence, which was said by our great chairman. ”

Zhang Sijiu: ??? What?

Yang Yuanding's face was deep: "Comrades still need to work hard. ”

Zhang Sijiu earnestly encouraged, and even brought a little bit of dog legs: "Then let's cheer together!" ”

Yang Yuanding looked up at the sky: "At my age, I am under pressure that does not belong to this age. Si Jiu, I think that I will definitely become a great man in the future. ”

Zhang Sijiu: ...... How do you say a word? Pretending to be a criminal? That's about it.

However, in order to encourage her comrades, she still nodded very cooperatively: "Definitely, it is necessary, they don't write a biography for you at my own expense!" ”

Yang Yuanding's eyes lit up: "Eh! Don't say it, it's a good idea! So, you write for me, and I'll write for you—"

Zhang Sijiu was completely refreshed.

She struggled to suppress the shock, "Do you want to do it?" ”

"!" Yang Yuanding came back to his senses from his imagination and did not hesitate. And he also said very decisively: "When I send pocket money, I will prepare the tools first, and then you will operate it." ”

Zhang Sijiu also meant this, so he didn't hesitate: "I'll see it." ”

After deciding on it, Yang Yuanding suddenly blinked: "There is one thing, this one needs to use rapeseed oil?" Does any other oil work? ”

Zhang Sijiu was asked like this, and he was immediately stunned, and after pondering for a while, he said with difficulty: "It must be vegetarian oil, and the meat oil will solidify." When I did this experiment, I only used canola oil. But now that the conditions are limited, you can try other meat oils. But try to keep the impurities as little as possible—"

In the process of producing penicillin, the control of impurities is key.

Once the bacteria grow, the wave is considered a failure.

Zhang Sijiu and Yang Yuanding looked at each other, and no one spoke out for a long time.

Vegetable oil is there. But it's all sesame oil, tung oil. Sesame oil is expensive and has a strong taste, while tung oil is used to light lamps, and there are too many impurities in it.

Yang Yuanding sighed: "Otherwise, wait?" Wait until the beginning of spring to plant rape? ”

Zhang Sijiu thought for a while and shook his head: "Then you have to wait a year, let's try sesame oil first." But I'm not sure if it will work. ”

Yang Yuanding nodded: "Then try it first." However, it is best that canola oil and peanut oil, and even soybean oil, can be made early. ”

He sighed: "Although boiled vegetables are very healthy, they ...... I really want to eat stir-fried food after eating too much! And dry pots, fried chicken, hot pots—"

There was a soft sound of "grunt", which was the swallowing sound of Zhang Sijiu and Yang Yuanding's tacit understanding.

Then, the two tacitly stopped the topic again.

However, before preparing the equipment for making penicillin, Yang Yuanding's seeding machine came out first.

When the ox cart pulled the seeder to the door of Zhang's house, Xu's whole person was surprised: "This and this, this ......"

No wonder Xu was surprised, although the seeder looked strange, it didn't shock people. On the contrary, Zhang Xiaoshan, who was driving the car, and Yang County, who got off the carriage, were even more surprising.

The official uniform that Yang County Ling still wears, even the few Confucian scholars who came with him are dressed up, and they know at a glance that they are the scribes in the yamen.

These are characters that are usually difficult to come into contact with!

Xu Shi only felt very restrained, and couldn't help but wipe his hands on the apron before remembering to say hello.

And this kung fu, Yang Yuanding had already jumped down, rushed to Zhang Sijiu, and showed off excitedly: "Jiu Niang Jiu Niang, look and see, my seeder is finally assembled!" You try it! ”

Zhang Sijiu was also a little infected: "Really? Have you tried it after assembling it? What do you think? Is it easy to use? ”

"Just tried it in the garden and it was ok. It depends on how the ground is going. The excitement on Yang Yuanding's face couldn't be concealed, and he looked like he was gearing up, as if he wanted to practice it immediately.

Looking at Yang Yuanding's appearance, Yang County Ling had a headache and helplessness, and finally scolded, "Be safe!" ”

Then, Yang Xianling carefully discussed the matter of trying out the seeder with Xu.

Not only sowing wheat and barley, Yang County Ling also wanted to try sowing brassica.

Speaking of brassica, Xu was a little surprised: "Brassica? Isn't that a dish? Although it is delicious, there are too many plants, where can I finish eating? ”

"No, brassica can be used to extract oil." Yang Xianling explained to Xu with a smile: "Under San Lang's play, the test showed that brassica can be squeezed for oil, and it is not poisonous, and the quality is better than that of tung oil, whether it is used to light the lamp or to eat, it can be." The yield is still very good. It's just that I haven't planted it on a large scale before, so I want to try it this year. ”

Yang County Ling was very good-natured: "Although there are official fields in the county, but it is good land, I think, try it in ordinary farmland." Of course, we produce the seeds, and we harvest the final harvest. If the harvest is not as good as other land, our yamen will make up the difference. ”

Zhang Xiaoshan smiled innocently: "I should have come down, but Yang County Ling has to tell you a special word." Saying that you are the mistress of the house can't help but tell you. ”

Xu was embarrassed, but felt a little moved: "I promise, I promise." In the future, this kind of thing will be answered by Xiaoshan, so there is no need to talk to me. He's my man, I listen to him! ”
