In Zhu Yunxuan's previous life, he read many historical records.

He tried hard to remember,

Sweet potato appeared probably around 1600, that is, during the Wanli period of the late Ming Dynasty, and was introduced to the Central Plains by Western missionaries.

There are still hundreds of years to go before this moment.

Later, it was slowly promoted nationwide, and as a major food, it was loved by many people.

"Book of Fujian·Southern Production" also records that sweet potatoes are "moist and edible, which can be boiled or ground into powder... Raw food is like eating kudzu, cooked food has a color like honey, and its taste is like cooked water chestnuts. When stored raw, it has a honey smell and a fragrant smell."

"In the room".

However, Zhu Yunxuan did not think that the sweet potato would really appear that late.

Information in ancient times is blocked. Generally speaking, it should take some time from the actual appearance to the time it is recorded in books.

Even if someone knows about sweet potatoes, they will only regard them as a relatively common food.

According to official historical records, it may even be decades or even longer.

After all, productivity was underdeveloped in ancient times and message transmission was also lagging behind.

Maybe a certain village has been cultivating silently for decades before it was discovered by a famous literati and recorded in books, becoming archaeological evidence for later generations...

But the actual time and source of its emergence have long been unknown.

This is also the reason why many scholars in later generations have repeatedly studied and recorded it.

I just want to find some clues between the lines that others have not noticed.

Therefore, if you calculate it this way, the chance that a merchant will bring sweet potatoes to Nanjing at this time is probably not small.

Maybe it had appeared earlier, but no one noticed?

Zhu Yunxuan is full of energy.

Originally, the sweet potato thing was something he thought of on the spur of the moment in order to answer Lao Zhu’s question.

Now it seems that it may actually be feasible.

Thinking like this, Zhu Yunxuan became energetic.

He took Ying'er's soft, boneless little hand and said, "Come on, come with me to have a look!"

Ying'er's hand froze slightly, but immediately returned to normal, and followed Zhu Yunzhen obediently.

On the pier, merchants from all over the world were shouting about their products.

Some people even set up a street stall.

Many people in the city will also visit Ma from time to time to see if there are any novelties.

Even many wealthy young men enjoy it.

If you are lucky and buy good things from overseas, you can give them to the girl you like.

Zhu Yunxu held Ying'er's hand and looked carefully at the dock.

In my ears I could hear the shouts of vendors in various accents, and even strangers from other countries shouting in broken Mandarin.

"Hey! Come and take a look, gems from the Western Regions..."

"Pearls, pearls! The best pearls from the West, whether used in jewelry or pearl powder, are excellent. The price is negotiable."

"Come and see amber, this texture, this color..."

"Good spices, good spices!"

"Persian cat, Persian cat! Take a look, it's a strange beast from a foreign country!"

Walking on the bustling pier, Zhu Yunxuan felt as if he had returned to the night market of later generations.

This feeling is very strange, making Zhu Yunxuan's eyes slightly out of focus.

However, he didn't forget about business and looked carefully to see if he could find the strength of the sweet potato.

"It's really lively here." Zhu Yunxi sighed while watching.

A small pier has everything you need.

Spices, corals, amber, pearls, gems, crystals, etc., as well as rare birds and animals...

These are all from overseas.

No wonder so many people come here.

Ying'er on the side chuckled and said: "Fourth Master, I don't know, there are activities here every first and fifteenth day of the lunar month!"

"Oh? It's so interesting." Zhu Yunzhen said while looking around.

I took Ying'er's hand and was about to leave, but suddenly I felt that Ying'er was standing still.

Zhu Yunxuan looked back.

I saw this girl looking at the pure white kitten in the cage with a look of joy on her face.

The kitten is not big yet, only about the size of an adult's hand. It has long hair and twinkling blue eyes. It seems to have curled up into a ball out of fear, making people unable to help but love it.

It was probably the first time I saw such a cute animal, and Ying'er's eyes were shining with strange light.

There is also a gentle smile on his face.

Zhu Yun was so happy, a woman’s nature always has a hint of motherly love!

Speaking of which, this girl Ying'er also helped me a lot this time.

Moreover, during this period, I have been taking careful care of my diet and daily life, which can be said to be a dedication.

Thinking of this, Zhu Yunxian smiled and asked: "Do you like it?"

"Ah? Ah!" Ying'er suddenly came back to her senses, her face turned slightly red, and she was so embarrassed: "Ying'er was distracted for a moment, fourth master, don't blame me."

Zhu Yunxuan smiled and said: "Let me ask you, do you like it?"

"Ah?" Ying'er was flattered and looked at Zhu Yunzhen blankly, then at the kitten, and was speechless.

Seeing this, Zhu Yunxuan said to the entourage (guard) on the side: "I bought it."

"Yes."

……

Holding the kitten in her arms, Ying'er was as happy as a child, and she thanked her repeatedly: "Thank you, Fourth Master, thank you, Fourth Master."

The joy that cannot be hidden in her eyes seems to make people empathize with her.

The beauty was eye-catching, and Zhu Yunzhen was in a good mood. Thinking that it was still early anyway, he took Ying'er to a spice stall and bought a lot of spices for Ying'er.

Seeing Yinger's overjoyed look, Zhu Yunxuan couldn't help but joked: "Ying'er, you smell very good. After using these spices, it will definitely smell better."

"Ah! Fourth Master..." Ying'er's face turned slightly red, obviously a little embarrassed.

After all, no matter how young Zhu Yunxuan is, he is still a man.

Zhu Yunzhen didn't think too much, and said with a smile: "Just take it."

"Thank you, Fourth Master." I don't know whether it was because of shyness or being embarrassed by the favor, but Ying'er's face was as red as a ripe peach.

Zhu Yunzhen took Ying'er around to look for sweet potatoes, and at the same time bought some pearls and jewelry for Ying'er.

Anyway, this little money is nothing to him.

Ying'er, on the other hand, was flattered along the way and was so happy that she even smiled from the corners of her eyes.

Just when Zhu Yunzhen walked to a stall selling dry goods, a voice suddenly came from behind him.

"Found it! Found it!!"

Zhu Yunxuan frowned slightly and turned back.

I saw a fat man sweating profusely running over in a hurry, his face flushed with excitement.

"Who is it?" The guard dressed as an entourage shouted, stretched out his hand and pushed the man to the ground.

Their mission is to protect Zhu Yunxuan.

He must not be contacted by suspicious people.

If something happens to the grandsons of the Four Emperors, even a hundred of their heads won't be enough.

Just when several guards were about to take down this man, Zhu Yunzhen waved his hand and said: "It's okay, stand down."

It turns out that the fat man is none other than the eunuch Feng Dazhuang.

As the grandson of the emperor, there will naturally be no shortage of people around him to serve him.

The eunuch Feng Dazhuang is the closest person.

However, he was sweating profusely and his clothes were messy, and he didn't look half as usual.

The guards usually guard the outer courtyard, and they don't have many interactions with people like Feng Dazhuang who stay in the inner courtyard all day long.

He was running so fast just now that he didn't recognize him for a moment.
