He was especially astonished when he saw that green soybeans had amazing anti-cancer effects, his mouth agape and his eyes filled with disbelief.

His mouth opened slightly, as if he wanted to say something, but the shock choked him up.

The rich medicinal value of soybeans also impressed him.

It was as if he had discovered a new continent that had never been explored in a medical field that he thought he was familiar with, which instantly ignited his strong desire to explore and his enthusiasm for research.

He secretly resolved to devote himself wholeheartedly to in-depth research on the medicinal value of soybeans, leaving no stone unturned in exploring any subtle clues or possibilities.

He dreamed that he might be able to discover some truly beneficial results for people's health from these seemingly ordinary soybeans.

That would undoubtedly be a great and meritorious deed, truly benefiting countless people.

To provide a solid guarantee for the well-being of all people, so that everyone can enjoy the beauty of a healthy life.

Qin Qianluo meticulously and carefully recorded every possible use of soybeans that she could think of.

After confirming that nothing was missing, her thoughts gradually shifted to the issue of the cellar.

In ancient times, before the advent of modern technology like refrigerators, properly storing grains and fresh vegetables was a long and complex process.

Cellars are undoubtedly the most ideal choice for maintaining freshness and edibility for a long time.

Although the farm's warehouse contains refrigeration units taken from the space, those refrigeration units might be just ordinary items in modern society.

However, in this day and age, its internal structure and precision components are complex.

With the current technology and resources, it is really difficult to produce it, let alone promote it on a large scale to benefit the people.

Qin Qianluo began searching for information about the construction of the cellar in the space's library.

At first, she thought to herself, a cellar is just a pit dug underground, as long as it can store things.

But when she actually delved into various books, she was shocked to realize that her previous ideas were far too naive and childish.

This seemingly simple cellar actually contains a great deal of knowledge and intricacies.

From the feng shui and topography of the site selection, the texture and structure of the soil, to the precise measurement of the depth, width and height of the cellar.

Then there's the setting of internal ventilation openings, the arrangement of moisture-proof and insect-proof measures, and so on.

Each of these is a crucial step that requires careful planning and meticulous consideration; it is far from being as simple as digging a hole.

Take the types of cellars, for example; they come in all shapes and sizes, each with its own unique characteristics.

Among them, the L-shaped (round) cellar has a unique advantage in storing items due to its unique structure, and the ratio of its depth to diameter needs to be carefully considered.

Such cellars must be at least 2.5 meters deep, with passageways typically around 4 meters wide. Their unique circular structure helps maintain internal temperature and humidity.

Suitable for storing tuberous crops that are easy to store, such as radishes, sweet potatoes, and potatoes.

A linear (square) cellar is more suitable for areas with shallow water. When building it, sturdy wooden poles are needed for support to prevent collapse.

Then cover it with a thick layer of straw, and then cover it with a layer of soil. Its internal space is relatively regular, which is quite suitable for storing some large-volume grains.

There are also semi-shaded (square) cellars, which are usually built by digging a shallow pit underground and building walls above ground with bricks or adobe bricks.

The top is covered with sticks, straw, etc., which cleverly utilizes natural light and temperature conditions to create a relatively stable environment for the stored items.

It is especially suitable for storing various seasonal vegetables and fruits, and can maintain their freshness and taste to the greatest extent.

However, each method of building a cellar requires precise skills and extensive experience.

Not to mention how to adjust the depth and width of the cellar according to different terrain and soil conditions.

Ensuring a reasonable spatial layout within the cellar was already proving to be quite challenging for Qin Qianluo.

Besides the structural issues of the cellar itself, the location is also of paramount importance.

The ideal location for building a cellar must be on high ground to effectively prevent rainwater from accumulating and flowing back in.

At the same time, the location must be dry, and a low water table is one of the key factors; otherwise, the cellar will easily become damp, causing the stored items to mold and deteriorate.

The soil should have good water retention properties and a compact and firm structure, making it less prone to collapse or other dangerous situations.

From the perspective of practical convenience, it would be ideal to build cellars in people's own courtyards, as it would make it much easier to access items daily.

However, there is another issue that cannot be ignored: the oxygen content and ventilation conditions underground.

As a relatively enclosed space, the cellar has poor air circulation.

If the issues of oxygen supply and ventilation cannot be properly addressed, it will not only affect the quality of stored goods, but may even pose a life-threatening danger to people entering the cellar.
