Even though there was no sun in this Inner world, it was miraculously as bright as day.
Sun Cheng had even tested it and found that the temperature in this inner world was always more than 20 degrees, which was the most suitable temperature for most animals and plants to grow.
This small world could absorb all substances in the real world and decompose them to evolve itself.
In the past years, Sun Cheng had also discovered many secrets about this world.
For example, the length, width, and height ratio of this world was fixed at 100:100:10.
In other words, no matter how much the length and width of this world increased in the future, the height of the sky would always be one hundredth of their height.
At the same time, Sun Cheng also discovered that the height of this world was divided into two parts,'sky height' and 'land thickness'.
As for the sky and the ground, they shared the height of the entire space according to the ratio of 9:1.
For example, Sun Cheng's current Inner world had a height of 276 meters. The thickness of the land was 27.6 meters, and the rest was the height of the sky.
Although it seemed unbelievable, this was the true situation of his inner world.
In the past six years, the land that was continuously expanding in the Inner world was used very well by Sun Cheng.
In the center of the Inner world, he had set aside more than 20 acres, which was more than 10,000 square meters of land.
Sun Cheng used his Creator's Authority to purchase raw materials from the real world and built a three-door courtyard house.
There were fake mountains and courtyards in the courtyard house, and they were the kind that were more formal.
Back then, in order to build this courtyard house, Sun Cheng had been sneaking around in the dark as a 'cat burglar' and climbing walls to check out the houses of several wealthy merchants and big families in town.
Otherwise, people from families with high walls would not easily let people into the inner court.
There were already more than twenty people living in this courtyard house located in the center of the Inner world.
These twenty people were all women, and they were not old. The two oldest were only seventeen or eighteen years old.
They were all slaves that Sun Cheng had bought in the past few years!
In the end of the Qing Dynasty, which was constantly in turmoil and repeatedly ceded territory and paid reparations to the outside world, in order to survive, many people lived worse than dogs.
There were even people like the smoking addict, who was very common in this era.
Under the influence of the so-called " longevity cream ", there were many people who sold their wives and daughters for a few yuan.
Although Sun Cheng had a kind heart, he was never willing to look at those smoking people.
However, most of the female slaves he bought were poor people who had been sold by their father, who was a chain-smoking addict.
Their luck was pretty good. They were pretty and young.
Sun Cheng saw it when he was strolling around the dental shop, so he took the opportunity to buy it and put it into his inner world.
Usually, in addition to helping Sun Cheng take care of the courtyard house, they could also help him brew wine, boil sugar, and serve him at the same time.
Although Sun Cheng's body couldn't enter the inner world, he could summon them out when needed. It was quite convenient.
Anyway, Sun Cheng didn't plan to let these female slaves come into contact with outsiders after buying them.
Usually, they were all well taken care of in the inner world, so Sun Cheng was not worried that the secret of his small world would be exposed.
There were two dirt roads extending from the courtyard house. One of them was the dirt road at the back door. There was a forest dozens of meters away.
The size of the forest was more than 2,000 mu, and all kinds of trees were planted.
There were at least a hundred different species. Although most of them were common trees in Gui Province, there were also expensive trees such as rosewood and rosewood.
However, the trees here did not look tall enough. They were at most two to three years old.
A stream flowed through the forest, around the courtyard house, and towards the front door of the courtyard house.
Fish and shrimps could be seen swimming in the stream, giving it a unique atmosphere.
Not far away from the main entrance of the courtyard house, more than ten acres of land had been cleared on both sides of the dirt road.
On the left side of the land, there were ten types of fruits: bananas, apples, pears, oranges, peaches, grapes, grapefruits, longans, and lychees. Each type of fruit was planted on one mu, and each mu of land only had ten to twenty plants.
On the right side of the land, there were 11 types of vegetables: cabbage, radish, cucumber, lettuce, potatoes, pumpkin, garlic, green chili, red chili, green onions, and leeks. Each type was also planted on one mu.
These fruits and vegetables were provided to Sun Cheng and the people around him to satisfy their appetite.
Not far away was a pond, about 200 meters in length and width, and about 10 meters deep.
It was currently the largest water source in this small world. The stream extended from this pond to the forest.
There were also some fish in the pond. There were many varieties, and they were all caught from some rivers and lakes near Shangxiang Town during his leisure time.
Sun Cheng would often come here to get one or two to satisfy his craving. The taste was very delicious.
A hundred meters further along the dirt road was a boundless green farmland.
This area had a total of 8,000 mu of farmland, and it was filled with two completely different types of sweet potatoes.
These two different varieties of sweet potatoes were the best products that Sun Cheng had repeatedly selected and cultivated in the past six years.
It wasn't that he didn't want to plant other crops, but he had done it after more than a year of repeated experiments.
In the end, they found that only corn, potatoes, and sweet potatoes, which were not the main food crops that the Chinese were used to, had the highest yield.
It was the best way to save more people in this era of famine and disasters.
Among the three crops of corn, potatoes, and sweet potatoes, sweet potatoes had the highest yield and were the easiest to manage.
