Zhang Sijiu took a bath, washed his hair, washed his clothes, took a bite of porridge to satisfy his hunger, and hurriedly went out to find Yang Yuanding.

Yang couldn't stop it, so he complained to Xiao Song angrily: "You, eldest sister, don't go home all day, what are you doing?" How can a little lady be like this? How can I find my in-laws in the future? ”

Komatsu didn't dare to speak.

But Xiaobai did not hesitate: "Sister, make money!" Buy Sugar! ”

In Xiaobai's heart, Zhang Sijiu goes out = earning money, this concept is deep-rooted and cannot be changed.

After all, although the Xu family also went out to earn money, they never brought back food for their two brothers.

But Zhang Sijiu is different! Zhang Sijiu always has something delicious to take home! It's not much, sometimes it's just a piece of sugar, but !! That's delicious!

So here in Xiaobai, Zhang Sijiu is the person he likes the most, admires the most, and maintains the most.

And he was too young to understand Yang's question, he didn't need to answer at all, he just vented his emotions, but he felt that since his grandmother asked, he didn't know! Since you don't know, you have to answer it yourself!

The flesh on Xiaobai's face exudes seriousness and seriousness.

Yang looked at it, laughed angrily, and reached out to pinch Xiaobai's face: "You are really protecting her." When she grows up, you can protect her like this. ”

Xiaobai grinned a mouthful of glutinous rice teeth and patted his chest: "I, protect!" Eldest sister! ”

He also drew it with his hand: "For a lifetime!" ”

Seeing that the atmosphere was relaxed, Xiao Song also promised: "I will also protect my eldest sister for the rest of my life!" No one can bully my eldest sister! ”

After a pause, he also pulled Zhuangding: "And the little pumpkin!" The little pumpkin also follows to protect the eldest sister! If she doesn't do it, I'll beat her up!" ”

Yang couldn't hold back at all, and waved his hand in disgust: "Okay, okay, I know you like her." Let's go and release the ducks. ”

And the little pumpkin, who was trying to cook at this time, had no idea what was going on. I didn't know that I had been named by my eldest brother and arranged a mission.

Similarly, Zhang Sijiu didn't know that he actually had so many three guardians.

She found Yang Yuanding and opened her mouth to say: "I'll partner with you to do a research and development, let's set up a pharmaceutical factory, how about it?" ”

Yang Yuanding was tinkering with his own drawings, and when he heard this, he raised his head and looked at Zhang Sijiu blankly: "What are you talking about?" Pharmaceutical? Did I hear me right? ”

"That's right." Zhang Sijiu's face was serious: "Have you ever heard of penicillin?" ”

"I've heard that." Yang Yuanding looked inexplicable: "Who doesn't know penicillin." I also know that penicillin is penicillin. But that's not what you want to do, are you? I won't either. I can't do chemistry. ”

Zhang Sijiu's face was subtle: "Is it possible that penicillin is made from the product of mold and from the cultivated flora?" Is it a biological class drug? ”

Yang Yuanding was completely shocked: "Huh? Yes! It's not chemistry? ”

"Hmm. We can make penicillin locally. It certainly wasn't as pure as it is today, but at least antibiotics could have been used. Zhang Sijiu looked at Yang Yuanding and threw out a huge temptation: "Isn't your second brother going to take the martial arts examination in the future?" The injury will definitely not be a problem, if we have this ......"

Yang Yuanding's crazy heart moved: "Not only my second brother, my whole family can use it!" From cold and fever, to wound inflammation, from bruises and injuries to wives and children, it can all be used! ”

Zhang Sijiu, who had prepared a stomach full of words, looked at Yang Yuanding like this, and silently swallowed the words again.

That's ...... It's useless.

After all, it seems that Yang Yuanding is more excited.

Of course, after the excitement, the problem still has to return to reality. Yang Yuanding suppressed his heart and asked cautiously: "Is it difficult?" ”

"It's hard, it's not hard." Zhang Sijiu said honestly: "The steps are not difficult, but the difficulty is how to maintain the purity, how to preserve, and how to facilitate taking or injecting. ”

Penicillin is mold in nature and can easily fail or become contaminated if stored in the open air.

Yang Yuanding pondered for a moment: "I'll try my best to see if I can overcome these problems." You write down the steps and methods, and let's try to see if we can make it on a small scale, and only ensure that we can use it at home. Wait for the technology to mature, and then consider mass production? ”

Zhang Sijiu also meant this: "That's right, I also suggest it." Moreover, this thing can also be used by us to raise pigs. Some diseases of pigs can also be used. We can first see if there will be any side effects. ”

Yang Yuanding slapped his thigh, so excited: "Isn't this a coincidence!" Isn't this still in touch with our pig farm? What is it called? It's called a one-stop industrial chain! No, no, I feel like I'm going to pass out. My grandfather always said that I was not a business material, but you see, you see, I'm not one step away from being the richest man in the world! ”

Zhang Sijiu was stunned and watched Yang Yuanding spin around the room, and the look of madness made her can't help twitching the corners of her mouth: Your grandfather is quite right. However, if you dare to think so, I am embarrassed to hit you.

So in the end, Zhang Sijiu nodded with difficulty: "Yes, yes, yes, you are one step away from the richest man in the world!" "It's probably as far away as one of Sun Wukong's heels.

Yang Yuanding was completely immersed in his dream of becoming the richest man in the world, and after looking up to the sky and laughing three times: "I don't know if I want to leave a name in history!" When my grandfather sees it, how proud he should be! ”

Zhang Sijiu was silent. Although she wanted to echo the two sentences, she really couldn't open her mouth.

But Yang Yuanding didn't let her go, stretched out his hand and patted her shoulder, and said happily: "Don't worry, I'm the first, you're the second!" I won't forget you! ”

Zhang Sijiu moved away and nodded perfunctorily: "Yes, yes, Gou Fugui, don't forget." Why don't you get down to business first? ”

Yang Yuanding rubbed his face and tried to calm himself down: "Look at it, I'm so excited. Hey, why didn't you say it earlier? We have this technology, why are we worried? ”

"You're floating." Zhang Sijiu reminded Yang Yuanding: "Don't forget, if we are too public, we may also be killed." I advise you to keep a low profile. Otherwise, being burned at the stake is not a joke. ”

Yang Yuanding calmed down suddenly.

He let out a long sigh and sighed: "It really limits my development!" Time is not waiting for me! Time is not waiting for me! ”

Zhang Sijiu: ...... Is he really suffering from any disease of the central nervous system?

However, Yang Yuanding still glanced at Zhang Sijiu and wondered: "However, why do you suddenly want to do it?" You didn't mention it last time. ”

Zhang Sijiu told the patient he met today.

After listening to this, Yang Yuanding was silent for a long time, and finally sighed lightly: "Si Jiu, maybe, this is the meaning of our coming." It doesn't matter if you have money or not. If you want to do it, let's do our best! ”
