After briefly dealing with a few urgently needed territorial affairs, Ye Teng hurriedly led a group of civil servants and military generals to the center of the county about 2 kilometers in front of the yamen.

The vast central square appeared in front of you, and at the center of the square was standing a large black stele up to 10 meters high, with two buttons on the stele that only the lord could see, one of the keys was green, indicating that it could be used, and the other button was still gray, indicating that it could not be used yet.

One of the most important features of the territory's upgrade to the county seat has finally surfaced: opening the teleportation array.

Pressing to hold back the excitement in his heart, Ye Teng hurried forward, pressed the green button, and the system prompt sounded: It takes 10 million gold to open the teleportation array, is it open now?

"If you want money to die, can you not open it?" Ye Teng secretly cursed in his heart, but he had no choice but to agree, alas, life is like that, since you can't resist, just enjoy it.

In fact, Ye Teng had long known that opening the teleportation array was expensive, which was also the reason why he didn't dare to spend so much money from selling horses last time, if it wasn't for the harvest of the grassland this time, just by opening the teleportation array, Ye Teng's pocket would be empty.

And now the player doesn't know that the system also has a very evil setting, 10 million is just the starting price of the world's first player territory to open the teleportation array, and every time it increases in the future, the price will rise by 10%, is there a compound interest algorithm for all evils?

How expensive is it, exactly? Let me give you an example, China's total GDP in 1985 was about 910 billion, and then it grew at an annual rate of about 10%, and 30 years later, that is, in 2015, China's total GDP was about 6.89 billion, an increase of about 70 times, terrible?

Of course, China's GDP algorithm also includes factors such as inflation and currency depreciation. In fact, with an annual growth of 10%, the total in 30 years is about 17.5 times that of 30 years ago.

In this way, the top 30 will need about 175 million, the 60th will need about 3 billion, the 90th will need about 53.6 billion gold coins, and the 120th will need 937.9 billion.

Therefore, in the previous life, there were many players who were upgraded to the county level and achieved the name of a prince, but there were very few territories that could afford to open a teleportation array.

In other words, the number of princes is limited, and if you can neither rush to upgrade the top few generals in the world to the county seat, nor can you capture and hold at least one county seat, then what awaits you is not the position of the princes, but the way to surrender and annex.

There is no teleportation array in the territory, and there are too many inconveniences such as expedition and transportation, and in the era of the princes' struggle for hegemony, every county is a lord land, if people set the teleportation array to not let you use it, facing the thousands of miles of rivers and mountains of the Han Dynasty, you can only use two legs to slowly trek hard.

Therefore, if you want to obtain a teleportation array, for most people, there is almost no other way to obtain a system county or higher level city through conquest and try to defend it.

Of course, there is still a big difference between achieving the position of a prince through a system city and achieving the position of a prince through one's own territory! Because, the system city is only under your rule, not all loyal to you. For example, if you want to recruit soldiers in your own territory, as long as the popularity of the territory is high enough and there are almost no restrictions, you can theoretically recruit all the men of appropriate age. But the system city is different, you can't recruit soldiers, you can only recruit soldiers, to the other party willing, if the other party is unwilling and you force the conscription, it is equivalent to catching a strong man, not only will it bring permanent damage to the people in the city under your rule, but also if you don't get the official to force the people to rebel, it will happen.

To use a popular metaphor, the people of your own territory are equivalent to your family, and you have the right to allocate the property in the territory, the young and strong in the territory have the right to conscript, and the beautiful women in the territory...... Oh, as long as you're not a strong robber, you won't have much of a problem.

And if the system city is under your rule, those people are only equivalent to the employees of your company, and even the families of the employees, and the other party has complete personal freedom, and they only have a nominal subordinate relationship with you, and they do not even have a labor contract.

Of course, all this can also be improved slowly, as long as you can raise the people's morale, but unfortunately, the system city you want to raise the people's morale, and its difficulty is not the same as the territory you have built brick by brick.

The system city is more complicated by the existence of large and small families If you take the city down, there are side branches of the Yuan family and relatives of the Cao family, and they don't bird you much. Excuse me, what should you do?

If the strength is not enough and you can't even take over a system county, you can only take refuge in one party's forces, or become a puppet prince. The so-called pseudo-princes are the ones whose territories have been upgraded to the county level, and they have the name of princes, but they can't open a teleportation array, and they can't master a system city.

As time passed, the only way out for the puppet princes was to take refuge in the real princes according to their geographical location. Otherwise, the radius of one's own activities is too small, and there are many inconveniences in work, study, conquest, trade, etc., and the development will naturally be slower than others, and even the strength will become weaker and weaker, until it is destroyed by others.

Therefore, the nominal ticket to join the Princes' Club is a county seat, but the real threshold is to master a teleportation array.

In the future, the various forces will be divided into the following four types of relations according to their proximity: dependence, alliance, neutrality, and hostility.

The setting of the transmission fee by the princes is basically divided into four grades, the first level is the internal city, which is often set to no fee, and the dependency relationship is set to charge a lower fee, such as 1 gold; Alliances, a little higher, such as 2 gold, and a higher neutral relationship, such as 5 gold, are generally set to be unusable. The system will take 10% of all fees, and the rest will belong to the princes.

Should this information be told to the Yan family? Ye Teng didn't want to tell, but he didn't bother to tell because it didn't make sense at all. Of course, there is also the meaning of distressing Yan Ruoyu, telling the other party a piece of information that must be kept secret but meaningless to the other party, in addition to increasing the psychological burden of the other party in vain, what is the meaning? With the talent reserve of the Yan family, it is completely impossible to rank in the top 30 in the world, in other words, they will definitely not be able to open a transmission array.

Their real way out is to obtain a system city, and at this point, if the future conditions allow, Ye Teng doesn't mind helping them.

For the sake of the safety of the territory, Ye Teng set the territory teleportation array to be used by Yan Ruoyu except for the internal personnel of Tianma City. As for the cost, of course, it is free, otherwise the system will take 10% of it in vain, and it will be all your own internal money. Not charging the people is also the intention of hiding the wealth from the people, not to mention, Ye Teng is not short of that money now.
