In order to facilitate the care of sweet potatoes, Ma Lin simply lived in the empty house on the side of Xiannongtan during this time to facilitate the care of sweet potatoes. In addition, he plans to avoid the storm that brought down Liu Jin in August.

Because Ma Lin sent tens of thousands of taels of silver to Liu Jin, he had a relatively close relationship with Liu Jin. Although Liu Jin is greedy, he is still willing to do things when he receives money. After receiving so much money from Ma Lin, Liu Jin later saw that Ma Lin was smiling and very kind.

But Marin knew that with the outbreak of the anti-Liu Jin incident in August, the close relationship between him and Liu Jin would become a destabilizing factor. Therefore, Ma Lin recently simply hid in the Xiannong altar in the west of the city in the name of taking care of sweet potatoes.

Xiannong Altar was originally a royal sacrificial place, and Ma Lin, an outsider, could not easily enter. But the sweet potatoes offered by Ma Lin were too important, and Liu Jin helped to speak, so Zhengde specially approved Ma Lin to move in. However, in order to avoid being tongue-in-law, Ma Lin did not dare to live in the palace of Xiannongtan, but lived in the dormitory area of the ordinary officials on duty in Xiannongtan.

When there is nothing to do, Marin will personally come to the sweet potato area of "one acre and three points of land" to observe the growth of sweet potatoes. At the same time, make a pond nearby to process manure. The processing method is very simple, that is, the collected manure is mixed with plant ash and fish pond mud, and then put it in the pond to make fertilizer. However, a lid is closed to prevent rainwater from entering the pool and dissolving the salt in the three fertilizers. These salts, including nitrate and potash, are important fertilizer costs that cannot be washed away by rain. Moreover, the newly collected manure cannot be directly lowered into the field, otherwise it is easy to burn the seedlings.

In addition to these three main fertilizers, Marlin also asked people to add cut dead grass and dead leaves to the pond and soak and ferment them together. These dead grass and dead leaves contain various ingredients, and if they are burned, they produce plant ash. Therefore, when these dead grass and leaves rot in the pond, they contribute to fertility......

Everything Ma Lin did was recorded in detail by the junior official in charge of agriculture sent by the Ministry of Household Affairs of the Ming Dynasty, as an important reference for the promotion of sweet potatoes in the Ming Dynasty in the future.

Now Marin seems to have really become a farmer, soaking in "one acre and three points of land" all day long. One day, after returning from the field, Marin drank the imperial wine given by Zhengde, and was a little absent-minded......

As Marin thought, these sake were not high-alcohol liquors that were popular in later generations, but ordinary low-to-medium sake liquors. Among them, rice wine and rice wine are more common. After all, in this era, the people of the Ming Dynasty were influenced by the literati and did not like high-strength wine very much, but preferred low-alcohol wine like ordinary literati.

One day, when Marin was drinking, he suddenly remembered - when drinking, how good would it be to eat yellow raw rice?

Then, Ma Lin suddenly remembered that when he came to Daming, he seemed to have brought hundreds of catties of peanuts. And these peanuts are indeed the best appetizer......

So, Ma Lin tried to send someone back to the wharf at Weidagukou in Tianjin, and brought hundreds of catties of peanuts and rice to the capital on the ship......

Soon, hundreds of catties of peanuts were sent to the capital. Ma Lin didn't say anything this time, just picked out some peanuts, made some fried peanuts in oil, and sprinkled some salt and pepper......

Suddenly, a strong aroma came from the imperial dining room in the palace......

The aroma of fried peanuts is very strong, and it tastes very fragrant. Marin has always felt that fried peanuts are the best accompaniment to alcohol. And Zhengde, the outstanding representative of the bear child, quickly fell in love with this taste after tasting it......

In addition to the ordinary fried peanuts with salt and pepper oil, Marin also had people take some chili sauce from the boat and make fried peanuts with spicy oil......

In this way, peanuts and chili peppers, two important foods, appeared in the Ming Dynasty at once, and they were quite valued by Emperor Zhengde.

Of course, in terms of meaning, peanuts and peppers cannot be compared with sweet potatoes and potatoes. However, when it comes to the popularity of the two, they must surpass the sweet potato. Then, peanuts and peppers naturally became two important crops ordered by Emperor Zhengde.

However, since there is not much time to sow now, Marin can't sow now. Unless, you can build a warm house, so that you don't care about the climate, you can grow peanuts and peppers as usual even in the winter......

……

At this time, the whereabouts of the nine Galapagos tortoises that Marin had offered were also decided—they were placed in the Qin'an Hall in the Kunning Gate (Shunzhen Gate) near the Xuanwu Gate at the north gate of the Forbidden City......

The Qin'an Hall enshrines the northern god Xuantian God in Taoism, also known as the Xuanwu Emperor, or the Zhenwu Emperor. Of course, Emperor Zhenwu was actually forced to change from "Emperor Xuanwu" to "Emperor Zhenwu" during the Qing Dynasty in order to avoid the name of Kang Mazi "Xuanye".

And what is Xuanwu? It's a turtle! Therefore, these 9 Galapagos tortoises, which represent the Xuanwu Turtle, are enshrined in the Qin'an Hall in the north of the Forbidden City, near the Xuanwu Gate, which is the best choice. After all, the Qin'an Hall was originally dedicated to the Xuanwu Emperor, and now it is very suitable to support 9 Xuanwu Turtles.

But at this time, Marin suddenly remembered - no, almost forgot the life habits of the Galapagos tortoise......

……

After all, the Galapagos tortoise is a tropical tortoise from near the equator, and it's summer, so it's all good to say. But by the time autumn and winter arrive, these turtles, adapted to the tropical climate, are likely to freeze to death......

And if it freezes to death, it will be a big deal......

……

From a modern point of view, perhaps the Galapagos tortoise offered by Marin is far less practical than the high-yielding sweet potato. However, in the superstitious ancient times, the top-level auspicious "Xuangui" that can make the emperor appear more "destiny" is obviously more important than the more practical sweet potato......

A cold sweat suddenly began to break out on Marin's forehead......

So, Ma Lin hurriedly sent a message to Emperor Zhengde and asked for help in building a comfortable place for the 9 turtles to live like spring all year round......

……

What does it mean to be a "comfortable place to stay"? In fact, to put it bluntly, Marin plans to build a glass greenhouse for nine Galapagos tortoises. In this way, even if the cold winter arrives in the north, there is no need to worry about the nine Galapagos tortoises freezing to death......

Emperor Zhengde was originally a very curious bear child, and after seeing Ma Lin's application, he quickly let them come from Xiannongtan to the Qin'an Hall in the Forbidden City. Then, he came to observe how Marin helped the nine "turtles" build comfortable shelters that are "like spring all year round......

……

What's so difficult about building a glass greenhouse? While Ma Lin sent people back to the ship to transport the plate glass brought from Taiwan Island to the capital, he personally led a group of masons from the Ministry of Industry to the Qin'an Hall in the north of the Forbidden City and began the construction of the glass greenhouse......

In order to ensure the success of the construction of the glass greenhouse, Marin personally went into battle and commanded the masons sent by the announcement to build the glass greenhouse. That stance...... Ma Lin has directly changed from "Grandpa Ma" to a professional "horse foreman" who builds greenhouses......
