Looking at the people kneeling under the city tower and kowtowed to him sincerely, Xiao Changyi said loudly: "Please rest assured, please don't worry, I will do my best."

"Thank you Prince! Thank you Prince!" The people cried and thanked them all.

Xiao Changyi's arrival made them find their backbone and made them suffer from hope again. Even though the hope was slim, they still chose to believe in Prince Xiao Changyi, and believed that Xiao Changyi could let them survive and live a stable life again.

Once upon a time, the country of Xiyun was invaded by other countries, and the country was not peaceful at all. It was Xiao Changyi who repelled the country's invasion and restored the country's stability in Xiyun, so that they no longer had to worry about being afraid of being afraid every day, but fear that the country would be destroyed. Now, they hope that they firmly believe that Xiao Changyi can still make them no longer worry about being afraid every day, and let them live a stable life again.

She quietly looked at her husband's side face, and her husband's side face was fair and looked at the people below, and her husband's side face was cold and tough, like a towering mountain, which was trustworthy and admirable.

And she is proud of having such a husband!

After appeaseing the people who wanted to leave the city, An Jing and Xiao Changyi walked into the palace.

On the way back to the palace, An Jing and Xiao Changyi didn't say anything, just walked quietly, and were in a heavy and depressed mood.

This place is really not happy now.

While returning to the palace with Xiao Changyi, An Jing thought about what modern people would do if they encountered a plague.

In fact, she was thinking about this on the way to Nanshen, but the conditions here are really limited and her technical level is limited. In addition, she is not a doctor and does not know how to cure the plague, which makes her unable to do so now.

In the palace, someone has arranged a room for them.

When An Jing and Xiao Changyi went to the room where they lived, there were only two of them, and there were no outsiders. Wen Jing said: "My husband, there was something called isatis root in my past world. It has the effects of clearing heat and detoxifying, cooling blood and relieving throat. It is often used for poison during plague, hot and sore throat, etc. If we also have isatis root here, we might be able to control the epidemic."

"Isatis root?" Xiao Changyi frowned, pondered and thought for a while, before shook his head and said, "I haven't heard of it."

An Jing said: "I have never heard of isatis root here, but I think there should be one here, but it just doesn't appear, or it's not called this name."

Xiao Changyi said: "What does it look like? You said, we can send someone to find it."

"It is the root of the blue... By the way!" An Jing suddenly slapped her head, "Zonglan! It is called blue! Because it grows very similar to oil cabbage, but it is obviously different from oil cabbage. Its root is isatis root, and its leaves can be extracted as dye to dye the clothes blue."

Song is a general term for cabbage vegetables in ancient words.

Here, Song also means this. When Xiao Changyi heard An Jing's words, he knew what the Sanglan looked like.

An Jing continued: "I used to use this syrup in ancient times as a dye at first, but was used as medicine later. Maybe the same is true here."

At this moment, An Jing is very grateful that when Hyundai had a second outbreak, she had a good understanding of this isatis root.

"My husband, let's go to the dyeing workshop to ask, and see how their blue dye comes from. Maybe it's really extracted from these blue leaves."
