In the expectation, only one circle of mold did not appear, but other miscellaneous bacteria appeared.

Such a situation represents a failure to make penicillin.

Zhang Sijiu stared at the situation in the petri dish, although he was mentally prepared, he couldn't help but tense his face and pursed his lips, he couldn't help but be happy.

Maybe it's because since he came to Da Song, everything he has encountered has gone quite smoothly, and Zhang Sijiu feels that his tolerance in the face of a successful mother has obviously decreased a lot.

Yang Yuanding was also a little disappointed.

But soon he raised a smiling face, grabbed Zhang Sijiu's arm and dragged the person away: "It's okay, how can anyone who does an experiment succeed so easily? Don't worry, don't worry. Let's try more, and we will succeed in the end. You know, we're already on the shoulders of giants! I don't know how much effort I've saved!"

He smiled brightly, seeing that Zhang Sijiu was still in a bad mood, he stretched out two fingers and tried to force her to smile on his face: "Come, smile, smile, think about Fat Dun - it has grown so fat, the castration technology will definitely be promoted next year, and you will be able to make money again!"

Zhang Sijiu dodged his fingers, a little speechless: "I'm not a veterinarian!"

Yang Yuanding's smile did not decrease, "Then do you earn this money?"

Zhang Sijiu didn't hesitate for three seconds to answer this question, and immediately gave the answer: "Earn."

If you don't earn money, you're a fool.

Dr. Teo is the wise Dr. Teo.

Under the power of money, the little resistance in Zhang Sijiu's heart quickly melted like spring snow seeing the sun, and even Haisheng had a little bit of anticipation-

Yang Yuanding looked at the corner of Zhang Sijiu's mouth with a little smile, and then breathed a sigh of relief, and then talked about penicillin: "I'll clean these up in a while, and then steam them all at high temperature. And then let's do it all over again? I also have some ideas for the oil extraction method I have studied, and if it is successful, after a while, we can buy some and try the oil extraction."

Zhang Sijiu looked at Yang Yuanding's energetic appearance and said sincerely, "Thank you."

Yang Yuanding wanted to make her happy just now, of course she understood.

That's why I thank him.

Yang Yuanding smiled as brightly as a little sun: "Who are the two of us? Thank you, thank you? Let's go, I'll treat you to a snack. My mother has been very kind to me lately, and she is willing to buy me even the most expensive cloud cake."

Zhang Sijiu squinted at him: "Mrs. Zhou has a mother's love for you. You can take less beatings, it's all up to her."

Yang Yuanding laughed twice, lowered his voice, and said, "You know that seeder, right? I heard that Cheng is going to Tokyo, and my father will definitely have a credit for it. I work hard, maybe my mother's destiny can be higher in the future, and my father can be promoted by the way. You don't know, my dad has been happy lately. I hum a little song when I go up to the hut."

Zhang Sijiu's head instantly appeared as Yang Xian Ling squatting there and humming a song while exerting his strength, and he couldn't dissipate it......

She was a little weak: Is this something I can listen to? Don't you want to have an image in Yang County?

So, she coughed, "Change the subject."

"My eldest brother is out this year, you know?" Yang Yuanding changed the topic with kindness, and his tone was a little proud: "I'm going to be off the list in the next few days. In order to avoid suspicion, my father asked him to go to the next county to take the exam."

Zhang Sijiu was a little surprised: "So early? Your eldest brother isn't that old. It's only sixteen or seventeen?"

"Sixteen, not yet seventeen. You don't know, he likes to pretend to be old. Hey, it's actually a high school student." Yang Yuanding's tone was full of contempt for high school students, but the next moment he added: "Of course, my brother is a high school student who is a top student, and he can be sent to Tsinghua University and Peking University."

Zhang Sijiu: ...... Okay, that's your brother, you have the final say.

"If he passes, I will definitely give him a gift, what do you say? The Four Treasures of the Study? He is not lacking either. Paper? It doesn't look like it's missing...... Book? Well, there is no shortage of ......" Yang Yuanding fell into a tangle, and finally looked at Zhang Sijiu: "What do you say is good for sending?"

"Send the lights." Zhang Sijiu did not hesitate: "Readers, you must stay up late to study. The oil lamps are too dim now. You design the design, and make a little oil lamp with a bright spot."

If you are short-sighted, you can also consider sending magnifying glasses - glasses, the technology is not up to standard, and the vision cannot be corrected. On the contrary, it is easy to make things worse.

Yang Yuanding slapped his thigh suddenly: "This is good, this is wonderful!" If you make it, you can not only send it to my brother, but also to my father! Si Jiu, you're so smart!"

Next, Yang Yuanding chattered about some things in his family, and Zhang Sijiu was forced to listen to a lot of gossip within the Yang family.

So much so that she had to say goodbye in a hurry to get rid of this trouble.

However, as soon as she said goodbye, Zhou Niangzi sent someone over to invite her over.

There is a burden on Mrs. Zhou's desk.

Seeing Zhang Sijiu coming, he beckoned with a smile: "Jiu Niang, come and have a look."

Zhang Sijiu walked over and greeted Zhou Niangzi: "Zhou Niangzi." jj.br>

Zhou Niangzi pulled Zhang Sijiu to sit down, opened the bag with a smile, and revealed the first few clothes and two small objects of rabbit fur: "I packed my luggage in the past few days and found that the clothes I made for Saburo's cousin before were made of the wrong size, and now I can only do them again, and no one will wear these few pieces." I also found two lying rabbits that I had worn before, and they were also eaten by insects, if you don't dislike them, take them back and wear them."

Zhang Sijiu was stunned, looking at the thick jacket in the baggage, and the snow-white rabbit fur, what did he not understand?

Zhou Niangzi found so many reasons, just to ask her to accept it with peace of mind.

Everyone has done their part, and it is not good to refuse again.

So, Zhang Sijiu raised a big smile: "Don't dislike, don't dislike, thank you Zhou Niangzi!"

"Then you try to fit it or not." Zhou Niangzi had also prepared a basket of persuasion words, but she couldn't use it at this time, so she couldn't help but purse her lips and smile, and she was very happy. As soon as I was happy, I couldn't help but want Zhang Sijiu to try it.

Zhang Sijiu did not refuse, and tried on all the clothes.

The clothes are a little oversized, but not too big. Zhou Niangzi pretended to regret: "In the end, it is not tailor-made, or it is too big." Fortunately, it's not too small, and I can barely wear it."

Zhang Sijiu cooperated with Zhou Niangzi's performance: "It doesn't matter, just collect some stitches, and I will let it go next year, and I can wear it again!" And now that I'm eating well, maybe I'll grow bigger."

Zhou Niangzi nodded again and again: "Yes, yes, yes, it can be like this." That would be great."

Then, even the lying rabbit Zhang Sijiu also wore it - in fact, it was a hat without a top. Women have to wear hairpins, and they can't wear hats, so this kind of lying rabbit that only surrounds the forehead and ears is a hat specially used by women.

There are also farmhouses, but they are all wrapped in strips of cloth, and they are not so particular.

Two lying rabbits, Zhou Niangzi smiled, "The other one is your second aunt's."
