The Great Demon King's melancholy expression startled everyone who approached her, especially those who knew what she was actually serving.

They advised her to see a doctor, take medicine, recite mantras, wear jewelry amulets, go to the theater, and find a beautiful little boy to have fun......

Luo Yi dismisses these well-intentioned suggestions, how can these stupid mortals understand the realm that my sister has to fight for the ratings of the Egg Pain Star program!

Not to mention this group of medieval residents, even her classmates must not be able to understand - Luo Yi can completely imagine how happy she would be to go to the orc planet to give birth.

Today's job of the Great Demon King is to inspect the construction progress of the Road and Bridge Corporation.

The Road & Bridge Corporation is another place where the Great Demon King has great expectations, not only for building roads and bridges for the whole of Tournest, but also for digging drainage ditches and irrigation canals for her rented land.

With one "dang" chariot driving through the wilderness, this thing is recorded to have appeared in the Western Han Dynasty, and was used by the great inventor Zhang Heng (who was also a great astronomer, geographer, painter, and poet) in the Eastern Han Dynasty after the Common Era...... He can be called an all-rounder in arts and sciences! So much so that some people mistakenly believe that there were many Zhang Heng during this period. The best part is that all of the above are his hobbies! His main position is a high-ranking official of the Han Dynasty! This is an ancient Chinese Leonardo da Vinci, whose name has been used to name an asteroid) improved into a drum car, a drum once on a mile road, a bracelet on a ten-mile road, so to speak, this is an ancient taxi.

In B.C., the ancient maps of China had reached a high degree of accuracy, perhaps based on the memorization car - in the early days of liberation, some local governments also used bicycles to measure the road, as long as the diameter of the wheel was measured, the distance could be calculated by multiplying the pi by the number of times the wheel turned.

After the road truck measured the distance of the road, the students who were the best at mathematics followed up to measure the height to determine the direction of the canal.

In BC, China's water conservancy projects reached a considerable height, such as Chengdu's Dujiangyan, the river water flow, drought irrigation, natural flooding and drainage, making the Chengdu Plain a country of abundance, has been used for more than 2,000 years until today, its designer and builder Li Bing and his son are also worshipped as gods - Chinese do not remember the inventor, in the Chinese temple, the worship is not the creator who killed his own creation, but the inventor who worked for the welfare of the people.

In terms of water conservancy facilities, another height reached in China BC is the qanats, also known as well canals, which are irrigation canals that lead snow water from the mountains all the way to the plains below the mountains.

The irrigation canal was not dug in the ground, but deep in the ground.

This was done to prevent the scorching sun of the Western Desert from evaporating the snow before it reached the bottom of the mountain.

However, if you dig all the ground, not only is the amount of work very large, but the man-hours can be imagined to be very long, but the wise ancients did not dig a single way to the dark!

The qanats are the crystallization of ancient mathematics and engineering, and they were built using the principles of operations research – to drill a shaft every other way, so that a long underground water canal could be divided into several working faces at the same time!

Of course, in order to achieve such parallel processing, the measurement must also achieve considerable accuracy, otherwise if there is too much difference, the two ends will not match!

Fortunately, the parish of Turnest is close to the sea, and the precipitation is still quite abundant, so Luo Yi does not need to use such advanced techniques for the time being.

But she does not dare to relax in the water conservancy work, there are many channels to increase income, but to increase food is only to work the land, maybe you can rob, but the premise of robbery is that your neighbor has food for you to rob.

Luo Yi is not optimistic about the food reserves of her neighbors.

On this day, the Great Demon King inspected the construction site according to the plan, but once again encountered an unexpected - according to this era, it seems to be expected - a brawl on the construction site.
