The fact that there was an epidemic in Yuzhou could be concealed from the lower-level officials and common people, but it could not be concealed from the top nobles in the capital.

Everyone just felt that the prince was meticulous and had taken everything into consideration. Apart from that, most people were more interested in the special medicine "penicillin" mentioned in the news.

If this medicine can save lives even when you're sick with the plague, what if it can also be effective for other illnesses?

It was surprising to hear that the thing was made by the prince. After all, they had never heard that the prince was proficient in medicine.

The thoughts of Yinzhi, Soetu and others were much more complicated.

When in Yuzhou, Yinreng acted as if he was certain that the plague would break out.

Could it be that he has some ability to predict the future?

The two pondered it, and soon thought of the plague that had been raging across the country since the end of the Ming Dynasty, so they didn't find it so strange.

Smallpox is also a kind of plague. It has appeared from time to time in the capital over the years. Perhaps Yinreng was just more thoughtful than others.

That day, after Yinreng came out of the Ganqing Palace, he seemed to have unloaded a heavy burden from his shoulders. The youthful vigor of a young man and the steadiness of an elder, these two very different temperaments intertwined in him, creating a unique demeanor.

When Yinsi saw Yinreng, he felt that his second brother seemed very different today.

Moreover, his eyes were a little red and swollen, and he looked like he had been crying. Yinsi's mind was full of thoughts, but he was tactful enough not to ask.

"Yinsi has met my second brother."

Yinsi stood up from his chair and saluted Yinreng.

"Xiao Ba, how come you have time to come look for your second brother today? Have you finished your homework?"

Yinreng was in a good mood today and was in the mood to chat and laugh with Yinsi.

Yinsi felt a little embarrassed.

"Not yet. I heard from my fourth brother that my second brother has a lot of calligraphy books. I want to borrow a few to copy."

"I see..."

Yinreng suddenly realized that Yinsi's handwriting was the worst among the princes. People say that a person's handwriting reflects his character, but Yinsi's handwriting was extremely inconsistent with his appearance.

In his previous life, Yinzhen once teased Yinsi in private, saying that his calligraphy was as slow as a dog's crawl.

Yinreng recalled, and the smile on his lips gradually widened.

"They say handwriting reflects a person's character. You were born as pretty as a little girl, so how did you develop such good handwriting?"

Yinsi's face flushed crimson when he heard this, and he called out in embarrassment,

“Second brother!”

He is a real man, how can you describe him as a little girl?

"Ha ha……"

Yinreng couldn't help laughing out loud.

"Okay, I won't tease you anymore. When you grow up a little, you will know that a good-looking man is also a huge advantage."

Yinsi curled his lips and didn't take Yinreng's words to heart.

He is a prince and doesn't need to use his looks to please others, so how can being good-looking be an advantage?

What he didn't know was that Yinreng's words were not an exaggeration. In his previous life, Guo Luoluo followed Yinsi wholeheartedly, and a big part of the reason was that he was so handsome.

Among all the princes, only the thinner Prince Nine could compete with him.

In fact, what Yinreng envied the most was that Yinsi's face was not only attractive to young girls, but even foreign merchants couldn't help but lower their guard when they saw him, and business talks went much more smoothly.

Who would have thought that such a handsome prince of the Qing Dynasty could actually be such a "black-hearted" person?

"Let's go to the study and carefully choose. Next time something like this happens, just ask Zhuo Xiaohu to take you to the study. You don't have to wait for me for so long."

Yinreng put his arm around Yinsi's little shoulders and carried him into the study.

An unignorable warmth surged in Yinsi's heart.

At his age now, he already understands what his background means.

But he didn't suffer much contempt for this, all thanks to the brother in front of him.

Over the years, there have been occasional frictions between him and his brothers, but they have never gotten to the point where they are difficult to resolve, and no one has ever ridiculed him for his background.

Even when he was studying in the Shangshufang, he was taken care of by all his brothers because he was the youngest.

Yinsi remembered all of it in his heart.

Arriving at the study, Yinreng pointed to a pile of calligraphy and paintings and said,

"Pick a few simple ones to practice on first. Don't damage them, or I'll beat you up!"

"knew."

Yinsi walked over to choose, and suddenly remembered something, turned around and asked,

"Second brother, are you getting married?"

Yinreng was stunned for a moment, then fell silent.

"It probably won't happen so soon. It probably won't happen this year."

"Why, you haven't even grown all your hair yet, and you're already thinking about having a wife?"

Yinsi's face turned red again.

"I'm not! I'm just a little curious about what my second sister-in-law looks like."

He often saw his eldest sister-in-law, Irgen Jueluo, in the Yanx Palace. She was a very gentle person, but was not very favored by his mother.

So far, his eldest brother is the only prince who has gotten married, and he does have some expectations for his second brother's wife.

In his heart, only a woman with a good family background, good looks and gentleness can be worthy of his second brother.

Yinreng smiled.

"You'll see it someday."

The next day, Hu Lianghong, the director of the Imperial Hospital, came to visit.

Yinreng also knew why he came, so he gave him the recipe for making penicillin that he had been using for the past few days.

In fact, penicillin was already recorded in the Ming Dynasty's "Compendium of Materia Medica", but no one has delved into the principles of penicillin's treatment, nor has anyone specifically studied how to extract penicillin.

Hu Lianghong was naturally very grateful and expressed his gratitude to Yinreng on behalf of the people of the world.
