Gu Xinran shook her head and sighed. She was powerless to do anything about these things and it was useless to think too much about them.

Looking at the present, with the death of the leader of Anzhuang, the assassination has come to an end. The danger has been lifted, and Jinzhou Prefecture has become a pure land for its people again.

Then just live and work happily here, and it would be best if you could lead the people here to live a good life as well, so that your journey through time will not be in vain.

After the matter was settled, Gu Xinran lived a leisurely life of recuperation, with everything provided for him.

The affairs of Shantou Village were handed over to the steward Zhao, who asked him to find talents with experience in orchard management and knowledge of fruit tree planting, and to first organize the villagers to cut bushes and dig pits;

Grandpa Gu and Yu Zhuangtou took full charge of leveling the land in the village to plant potatoes.

Even the opening of "Ruyuan Cake Shop" was presided over by Duan Yunchi. Of course, Manniang, Zhang Hong, Li Mingzhu, and the two newly hired assistants were all very capable. The cake shop's profits were not as high as the winery, but it still made at least a few hundred taels of profit every day.

She was responsible for providing her with good food and drink every day, and taking good care of her injuries, and a steady stream of silver and banknotes flowed into her hands.

Of course, Big Brother Gu, Xiao Mingzhan, and the eldest uncle also got to enjoy a lot of delicious food and drinks. As for the injury, she was considerate and kept it a secret to avoid distracting those on the battlefield.

During the past half month, the person who disturbed her the most was Doctor Zhang, who came to her house every few days to learn the culture and extraction methods of penicillin.

Gu Xinran first taught him to use rice water and potato juice to make a culture medium, and then collect the Penicillium mold from the oranges and put it into the culture medium;

After culturing, filter it, pour in rapeseed oil and stir, scoop out the grease after layering, and pour in carbon powder...

After several experiments, they finally succeeded in extracting the penicillin solution when Gu Xinran's arrow wound was completely healed!

That day was an auspicious day, the second day of the second month, when the dragon raises its head. In order to verify the efficacy of penicillin, Gu Xinran asked Doctor Zhang to take some pus from the patient's wound and put it into a small bowl containing penicillin solution.

After a while, a clear ring formed around the pus mass and the inflammation disappeared.

Doctor Zhang's face flushed with excitement as he shouted, "Look, little master! This penicillin is truly a miracle drug. The therapeutic effect is very obvious."

Gu Xinran smiled, "Not bad, not bad, but we have to experiment with it first before we can use it with confidence. Let's try it on rabbits first."

Doctor Zhang nodded. "Any new medication must be tested first. I'll take care of it."

Gu Xinran thought about how to use penicillin and felt a headache. She didn't care and let Doctor Zhang find a solution.

She said with some embarrassment, "Compared to external application or internal use, the fastest way for this medicine to work is through intramuscular injection or direct administration into the blood vessels."

Doctor Zhang was so shocked that his mouth opened wide. He had been practicing medicine for decades, and the medicine he used was either applied externally or taken orally. This was the first time he heard of such a novel method, and he was really enlightened. He thought that this little master was worthy of being called.

Gu Xinran ignored his unquestionable look and drew carefully, drawing out modern syringes and infusion equipment.

I explained in detail the principles and effects of the new medication to Dr. Zhang, who had accepted the new method of using the medicine, and asked him to find someone to make it.

In this era, there is no glass or plastic hoses, so we have to find various substitutes, which is really a headache.

Fortunately, Doctor Zhang was smart. He thought for a moment and said, "We can find a skilled blacksmith to make this syringe, and the hose can be replaced with a thin reed or pumpkin vine..."

Gu Xinran was happy and thought to herself that she had to believe in the wisdom of the ancients. They just had not seen modern technology, but their brains were not slow at all.

Gu Xinran gave a thumbs up and said, "Doctor Zhang is smart. I'll leave this matter to you."

Doctor Zhang thought to himself that these were just some clever tricks, and how could he compare with the young master who knew how to refine miraculous medicines? He didn't know where the young master learned his knowledge from, but it was so profound that it was incredible.

He was lucky to have such a young master, who could make new progress in his medical skills at the age of sixty. He would take care of the minor matters and readily agreed, "Leave it to me."

At this moment, Gu Xinran remembered the contraindications of penicillin and said seriously, "This medicine is not suitable for everyone. When using it for the first time, a skin test must be done first. Only after there are no adverse reactions can it be used for treatment."

After that, she tried it on her wrist and showed it to Dr. Zhang. Dr. Zhang remembered everything she did and said.

After everything was settled, Gu Xinran spoke ambitiously: "Once the equipment and experimental results come out, we will go to Funing Town to build a large workshop and establish a penicillin production base.

We are not aiming for profit, but selling it at a low price to benefit the people and soldiers, so that more difficult and complicated diseases can be cured."

When Doctor Zhang heard this, his blood boiled and he immediately took the drawings and the finished penicillin product and went to work.

After breakfast the next day, Gu Xinran was about to inspect the store when he was invited to the middle hall.

Grandpa Gu, Yu Zhuangtou, Duan Yunchi, Housekeeper Zhao and others gathered here, waiting for her to discuss the important matter of spring plowing.

After greeting each other and taking their seats according to their order of importance, Yu Zhuangtou was the first to speak: "Young Master, the dry land of the four villages has been leveled, and it's time to plant the rice. We can't delay the seeds any longer."

Li Yuan, who was standing to the left of Butler Zhao, continued, "County Lady Funing, Shantou Village has cleared two hills and is now ready to plant the fruit seedlings."

Li Yuan is an orchard management talent recruited by Butler Zhao.

The Maitreya-like man to Butler Zhao's right, the chief steward of Prince Qi's Jinzhou estate, spoke humbly, "Princess, the prince has instructed that this year's fine seeds be collected from you."

Duan Yunchi was even more direct: "Ranran, the good seed you promised me still counts!"

Gu Xinran thought to herself, "Good fellows, this isn't a discussion about spring plowing, they're all here to collect debts!" ​​But even if they didn't come, she was ready to notify them.

Fortunately, the space was good and everything was ready. She piled all the fruit seedlings and good varieties into the third courtyard on Lanzhu Road yesterday.

Gu Xinran glanced at everyone, smiled and shook her head, and finally her eyes fell on Duan Yunchi and glared at him.

Then he slowly stood up and beckoned, "Follow me, I'll take you to get the saplings and good seeds."

A quarter of an hour later, everyone arrived at the third courtyard and was shocked by the mountains of potatoes and several rooms of high-quality seeds.

In addition to the seeds needed for his own village and the two villages in Funing Town, Duan Yunchi gave 50,000 kilograms of three high-quality seeds. In addition to 40,000 kilograms of rice seeds and wheat seeds, Xiao Mingzhan also gave 30,000 kilograms of potato seeds.

It was the first time for the chief steward Duan Yunchi and others to see such evenly proportioned, plump and large grains of grain. They were all so shocked that they could not close their mouths and kept saying "tut tut" in amazement.

When Li Yuan saw the fruit seedlings, his eyes widened into slits and he was very satisfied.

Soon, all the seeds and seedlings were taken away.

There was no surprise when others pulled it, but when Xiao Mingzhan's people took over the seeds, Gu Xinran noticed a slight change in the space.
