"The Four Seasons Formation passed down earlier is already quite special, possessing numerous special effects, but you haven't fully explored them yet..."
In the fields of the Agricultural College, Zhang Mingtu spoke softly, his voice neither too loud nor too low, but it was clear enough for dozens or even hundreds of people present to hear.
"I think you're all familiar with the Four Seasons Formation. It's divided by the four seasons of heaven and earth, and follows the natural order. The most commonly used one is the Spring Formation, which is specifically used to promote the growth of various plants...
As one of the four sub-sections of the Yi Wood Formation, the Spring Formation allows all things to revive, the Summer Formation allows all things to flourish, the Autumn Formation is when crops flourish, and the Winter Formation suffocates all things and is not usually used directly..."
What Zhang Mingtu said were all common sense issues. After listening to them, the permanent residents nodded directly and no one did not understand.
Of course, there have actually been many changes.
The Four Seasons Formation mentioned by Zhang Mingtu, or the Yi Wood Formation, was not divided into so many parts on the original basis. It was originally just the Yi Wood Formation.
After all, most of the people in the agricultural colleges are not studying ordinary crops, but real spiritual materials and medicines, which are top treasures specially used for alchemy and spiritual practice.
Their growth period is not one year, but many years. Some take a long time to grow, even dozens or hundreds of years. This can only be cultivated under careful care.
The amount of Yi wood essence needed to cultivate them every year is huge.
However, all the major aristocratic families and royal families are very eager for it, and the demand is huge.
For this reason, the Yi Wood Magic Array was born.
After all, in the early years, if you wanted all kinds of spiritual objects, you had to go to the fields and the mountains to look for them. Not to mention that there was a lot of miasma and monsters in the mountains, the efficiency of this search alone was too low, which was unacceptable to many people.
Due to various related disadvantages, the cultivation of spiritual medicines and spiritual plants has been put on the agenda and has been continuously developing over the years.
Even as early as before Taizu founded the country, people had already begun to cultivate magical herbs in ancient times.
But the initial cultivation was not smooth. After all, the environment for the growth of spiritual medicines is extremely harsh, and the essence of heaven and earth is quite rich. It can only be achieved with various acquired environments.
At the beginning, we collected seeds of spiritual medicine and brought them back to the building to sow them. After all, the purpose of collecting seeds of spiritual medicine is to avoid planting them in poor and remote places and avoid many dangers, but the results were not obvious.
As a second best option, they could only practice in the corresponding area and find a similar environment, but the results were still not very significant. Until later, no one knew which formation master created the Yi Mu formation.
The Yi Wood Array can simulate the changes of the four seasons, and it is filled with rich Yi Wood essence, so all kinds of plant-related spiritual medicines and materials can grow rapidly.
Except for some special plants that grow in volcanic areas or deep under the sea and are difficult to cultivate directly, most spiritual plants can be cultivated and ripened little by little using the Yi Wood Array.
That could be considered the first rapid development in the world of cultivation. Of course, Zhang Mingtu later discovered through research that the Yimu Formation originated from the period of Emperor Wu, and was obtained by Emperor Wu after his expedition to the northern barbarians.
It is one of the methods of growing spiritual herbs passed down by the northern barbarians. It can be regarded as a very special method.
However, no one cared about it back then. Now when Zhang Mingtu thinks back on it, he can feel many differences.
"Among such a destitute race, there is such a perfect Yimu magic array that can produce all kinds of spiritual medicines and plants. From this aspect, it can be seen that the Northern Barbarians are indeed a race of gods, from a higher world..."
Of course, Zhang Mingtu did not directly teach what he had in mind to the many students present. Anyway, the origin of the Yi Mu Magic Array is still a mystery, and the original Yi Mu Magic Array was not what it is now.
After hundreds of years of improvement, the Yimu Magic Array is no longer the same as the original version. Many details have been added and many directions have been changed.
At least the Yimu magic circle, which was originally used to cultivate spiritual medicines and plants, has a strong essence that is poison to ordinary crops. If used to grow rice or potatoes, it will kill both of them on the spot.
After being improved by many people in later generations, it can now be said to be completely in line with the Yi Wood Formation of Daxia.
"When I inspected and probed the Yi Wood Formation, I discovered it could be divided into four phases: spring, summer, autumn, and winter. Different phases correspond to different functions. Autumn Killing and Winter Hiding would kill ordinary crops and absolutely must not be used. However, if it could be slightly manipulated to specifically target weeds and insects in the fields, using these two functions would actually have unexpected effects..."
Zhang Mintu was describing as he spoke, and before he finished, some people already looked excited and jubilant.
"No wonder I directly activated the Yi Wood Essence. Sometimes, plants wither before they even take root or sprout, before they truly mature. It's because the seasons change too quickly."
"I never thought there would be such exquisite subtle changes in the Yimu magic circle. The person who created this magic circle back then was truly a god."
Some people sighed repeatedly.
"No, it's not that the person who created the magic circle back then was powerful, but rather that Dr. Zhang had a unique idea in this regard. How could others have imagined that the Yimu magic circle could be divided so finely..."
The group of people below were all very happy. After expressing their admiration, they started to manually operate the Yimu magic circle.
