If you want to play Civilization IV, you'd better bring two materials, which will add many particularly interesting functions and scenes, as well as leaders, units, wonders, buildings and MOD.
Many new functions have been added to the two messages. For example, the god of war added a great strategist. After the great strategist appears, you can use it as a "military commander" to command specific combat units. This also allows other units in the same story to get a total of 20 one-time experience value rewards. Can let the unit have a higher upgrade. After joining the city, you can add two experiences in the units made in the city. You can also build a military academy to speed up the construction of your military units. You can sign a vassal state treaty with other countries, and a relatively weak country becomes a vassal state of another country. When the economic and military strength of the client country reaches certain conditions, it will automatically cancel the treaty. If your country is very big, then some cities on the border will be independent, and you can give them autonomy, then those cities will form a country, and the formed country will automatically become your vassal. You can also deny their autonomy, but people's dissatisfaction will rise. I usually give them autonomy, and when the border expands again, I will take it back by force.
Beyond the blade, on the basis of the god of war. You can start a company with great people. There are seven kinds of companies: standard ethanol company, which can provide oil with corn, sugar or rice, provided that the technology is plastic and founded by great scientists.
Grain grinding companies can use corn, rice or wheat to provide additional grain output, provided that the technology is refrigeration technology and is founded by big businessmen.
Comprehensive aluminum companies can use coal to provide aluminum, provided that the technology is a rocket and was founded by great scientists.
Innovative construction companies can use iron, copper, granite or marble to provide additional industrial capacity, provided that the technology is an internal combustion engine founded by a big engineer.
Civilized jewelry companies, if they have gold, silver or precious stones, can provide additional business income and cultural points, provided that the technology is mass media and founded by great artists.
Sid sushi company can use crabs, clams, fish or rice to provide additional food output, provided that the technology is medical and founded by big businessmen.
United mining companies can use coal, iron, copper, gold or silver to provide additional industrial capacity, provided that the technology is railways and is founded by big engineers.
A religious palace can be built, which can be built before the appearance of the United Nations, and its function is similar to that of the United Nations. At the same time, there is a corresponding bill to teach the palace, which cannot be implemented.
Random events: this is unique outside the blade. As the game goes on, there will be many random events. For example, before the discovery of oil, there will be an event that someone has discovered a flammable black liquid. This will give you two choices. First, it won't cost any money; second, it will invest in research, spend five gold coins, and show all the oil fields in the world at the same time, which is very helpful for development. There are many similar incidents, such as mine accidents, religious disputes, golden age, citizens' requests, and various natural and man-made disasters. When an accident happens, you will get some options to test your ability to deal with the accident. Of course, sometimes it is not an event, but a task, such as finding a sacred mountain, which will let you finish before the industrial age.
My favorite MOD is the next war, but it seems that there is only a blade of transcendence. Many new technologies have been added to MOD, such as cloning technology (you can build clone soldiers and need clone factories, but it will bring three points of dissatisfaction to the city) and shields (you can cover the city with shields, provided there are ecological buildings, and there are two kinds of shields, one is called shields, and the other is called deflection shields, which can reduce a certain proportion of combat damage and increase the life value and happiness of the city by three points). When the technology is complete, you can also build a mecha. It seems that three can be built, with a fighting capacity of 50, even more than the ordinary version of the main battle tank, as well as the fearless tank (with a fighting capacity of 80, it can be said that it is a land king and a national unit, and there can only be one).
