The location of the water conservancy project will naturally not be in the Taiji Hall.

The display of water conservancy projects is in the Taiji Palace, and the electricity generated through the water will produce brilliance in the Taiji Palace.

Even the Emperor Taishang couldn't help but look at this piece of splendor, because it was too wasteful to light up during the day, so the Taiji Hall was immersed in darkness during the day except for the location of the emperor's director, and those with windows could borrow some sunlight, and those without windows could only be in the netherworld, although Li Shimin was luxurious, but he was not too wasteful.

Especially when he was young, he still had momentum at this time, and he didn't think that he had to enjoy too much luxury and wealth, and a luxurious emperor must be matched by the stability of the whole country.

In history, Tang Taizong Li Shimin was no different from the general mediocre emperor in the late period, but although he became mediocre, he was able to enjoy the benefits brought by his early politics, and even not only he could enjoy the benefits Although the entire court fell into chaos, it still had a relatively prosperous development, and other countries still looked at Chang'an of the Tang Dynasty with a worshipful eye, and Chang'an of the Tang Dynasty was the most glorious city of this era.

Fan Jingjing feels that under the building without high-rise buildings, it is a very remarkable thing to spread a large city of one million people on the flat ground, and the big city of one million people is not only about building a house, Fan Jingjing can associate many things about people's livelihood, including the lack of a proper treatment mechanism for feces at this time, and their drinking water is a big problem.

What's more, at this time, there is no habit of burning gas, and a large amount of firewood is used, which will put a lot of pressure on the supply of wood around Chang'an.

Fan Jingjing couldn't help but sigh, using coal will pollute, and using wood will also pollute, and destroying water and soil is not a good thing for the entire Chang'an area.

It seems that the growth of people is a kind of harm to the earth itself, but when there are few people, this injury has time for the earth to recover, but when there are more people to a certain point, this kind of damage will never be able to recover, and people live in a place, if they live well, they will not want to move, the damage to a place is eternal, until the land can no longer bear it, people will leave, and then leave thousands of years to slowly recover.

For such a natural phenomenon, Fan Jingjing as a member of human beings is also a part of the harm to nature, although she wants to love nature, but also feels sorry for nature, no matter how between coal and firewood, she must make a choice, if after the unification of the Tang Dynasty, the entire population quickly flocks to Chang'an, the future fate is almost certain, not to mention that even the current permanent population is in a relatively dense state, and the forests around the denser population will be relatively damaged, and it will be too late to grow. Chang'an has been damaged for thousands of years, and the situation of bare land is becoming more and more serious, and a large surface is destroyed, which will affect the surrounding environment.

People still live scattered, and they will not harm the environment, but when people are separated, their strength will shrink a lot, and when nature competes with humans, human beings will be defeated and retreat, and finally become the food of all things.

The introduction of coal will soon be able to discover the function of coal, whether it will increase the use of a large number of people, lead to the irreversibility of the environment, the early occurrence of the industrial revolution, not to mention the addition of basic scientific knowledge brought by Fan Jingjing will accelerate this action.

If only the rise of the Tang Dynasty, with the ability of the Tang Dynasty can plunder the resources of many places, the resources of coal and iron, the most places in the north of Siberia, perhaps to persuade Li Shimin, to the north to send a little more troops, and then pull back the coal mines in the north, but want to pull back the minerals in other places, although the minerals will not be broken, but the people who pull the coal need food, so the demand for food will further increase, because it takes a long time to pull coal, so the final problem is the problem of transportation, If the traffic problem is not solved, a place cannot be developed, and when a place is developed, it will only accelerate the pace of people leaving.

The problem of food is also a problem of transportation in this era, after all, the power of livestock used in this era also needs food, although this food is not necessarily the food of people's mouths.

The ability to maneuver must have a flat ground, as well as tools to assist in moving forward, and these are many people want to steal, if there is no way to maintain the stability of law and order, the act of stealing alone will make people unbearable, the only way to transport is something that does not need to be valuable, that is, water pipes, but when people realize that the oil transported in the water pipes is valuable, the act of stealing will be more difficult to prevent, in the era of no law, people will do more freely when they violate others.

Speaking of these problems, Fan Jingjing really had a headache, in fact, strict punishment is the best way in this era of no choice, but strict punishment will produce a lot of innocent people, so that innocent people will sacrifice along with the strict punishment and strict law.

Then people outside the law still have to spend all kinds of energy to prevent everything, which is to increase the cost, increase the cost, and finally it will be calculated on the things that people use, so that the cost cannot be reduced, although the manpower at this time is very cheap, and people calculate the price of manpower, basically to let him be fed and clothed, as for other things, don't want it.

More people spend their lives thinking about how to be fed and clothed, and do not have the energy to bear any accidents.

will think about taking care of the people all over the world, and it is estimated that only her kind of leisure and nothing can be done, otherwise in fact, everyone living in the contemporary era is struggling in life, and there is no superfluous semantics in their hearts to strive to create new knowledge.

The birth of a knowledge takes time to accumulate, and it will only appear if it follows the trend, but it is very rare, most of the knowledge must be constantly improved and integrated in order to become a family of words, if it is just nonsense, it has disappeared after the passage of time.

The whole process of the celebration ceremony is from the outdoor to the indoor, so the first place to gather is not the palace, but outside Chang'an City, where the flowing water gathers, because it is the water source used by the royal family, so this water source must be very clean, so it also flows down from the mountain, and this route is closed by the royal family, and can not be used by the common people, and the common people in fact, if no one is stationed next to them, the people will think that they can use the land in the world, unless it is a rich man.
