"Congratulations to the player for meeting the promotion criteria for Lone Boat's territory, did you spend 100,000 gold to promote Xanadu Town to a small city?"

The system message appeared as expected. Lu Yao glanced at the system message and decisively chose to upgrade. With only 100,000 gold, at present, except for underage children and beggars and other unemployed vagrants, basically all players can reach it, let alone him.

100,000 gold was deducted from the territorial funds, and Xanadu Town underwent a new round of expansion.

A day later, Xanadu had been upgraded to a city, much larger than before. It was originally a little crowded, but now it is obviously much more sparse.

The new Xanadu City is significantly more advanced than the town-level territory. The most obvious of these is not the expansion of the territory by a hundred miles, but the population cap. The population limit of 50,000 directly erases the population that has been overloaded before. However, at the current refresh rate, it won't be long before it reaches full capacity again.

Lu Yao looked at the following indices slightly. Not surprisingly, except for the popular sentiment index, which remained above 80 points, the other three indices all fell sharply. In particular, the cultural index as well as the urban defense index.

The cultural index needs to improve the literacy of literary classics and the cultural popularization of the people in the territory. Leaving aside the literary classics for the time being, the most obvious improvement is to attract literary masters. Cai Yong was once again remembered by him. It's just that this literary master is stubborn and old-fashioned, and he is still struggling with the death of the young emperor and the Empress Dowager He. It seems that there is no way to recruit them until they untie the knot.

To improve the cultural index, Jia Xu, who is also a cultural person, is obviously far inferior to Cai Yong.

The city defense index is more important than that. The hidden setting of this index is to reveal potential enemies around the territory. The lower the index, the more hostile opponents there are around the territory, or the opponents are already incompatible.

However, Lu Yao was not worried.

Looking at the entire Zhuya Prefecture, no one is a paradise town...... No, it's already a rival in Xanadu City. Zhao Yun, Huang Zhong and other famous generals, even if the original Chiyang Village forces attacked again, he was sure that he would be able to repel the enemy army without the help of Jiuli Man.

After reading the various indexes, Lu Yao locked his eyes on the new buildings in the territory of the small city scale. Upgraded to the size of a small city, there are not many new basic buildings, only four types: the primary urn city, the primary city gate, the primary sewer, and the primary horse farm.

Primary Urn City: One of the main defensive buildings of the city, which can strengthen the defense of the city or pass, requires 10,000 units of stone and 1,000 units of wood, and is expected to be completed in one day. Auxiliary buildings: arrow towers, gate gates, pheasant moats, etc.

Primary City Gate: One of the main defensive buildings of the city, which can strengthen the defense of the city or pass, requires 5000 units of stone and 3000 units of wood, and is expected to be completed in one day. Outbuildings: Broken Dragonstone.

Primary sewer: one of the main civil facilities in the city, mainly used in the city sanitation and other aspects, can slightly enhance the people's morale, need 20,000 units of stone, 10,000 units of wood. Outbuildings: None.

Primary Horse Farm: A place where horses are trained and raised in the city, which can survive for 1,000 military horses (note: it needs to be built outside the city), requires 300 units of stone and 10,000 units of wood, and is expected to be completed within one day. Outbuildings: Stables.

Compared with town-level territories, the resources required for new infrastructure in small-town territories are significantly higher. Only four basic buildings require a total of 35,300 units of stone and 24,000 units of wood. If it weren't for the large amount of resources he had accumulated before, Lu Yao would have been a little heartbroken.

A day later, the four new base buildings were completed, and the other buildings that needed to be upgraded were also upgraded. Lu Yao made a special inspection and was quite satisfied with the current situation in Xanadu City.

The primary urn city is a new outer city at the city gate, which separates the city gate. The gate gate of the urn city is not in the same straight line as the city gate, so as to avoid being attacked by siege props such as enemy chariots.

The construction of the urn city is equivalent to expanding the area of the city, and in wartime, the terrain can be controlled in a small area when the enemy enters the city, ensuring that the enemy cannot deploy a large army, and greatly improving the ability to defend the city.

The effect of the primary gate is the same as that of the primary urn city, both of which increase the defense of the city. The half-foot-thick gate makes it difficult to penetrate just by looking at it. Behind the city gate, there is a broken dragon stone with a thickness of three meters and a weight of about thousands of catties.

In the urn city, the city gate was broken, the broken dragon stone was put down, and it was difficult to break the broken dragon stone polished by the whole boulder. If you want to attack the city, you can only force it through the ladder, which undoubtedly greatly increases the difficulty of the siege. Figuratively speaking, it has jumped from ordinary to hell.

Needless to say about the primary sewers. But there is no one who does not know the importance of sewers to a city. It has just been built, and the sanitary environment in the city is obviously much cleaner and tidier. There was also a little more happy smile on the faces of the people.

For ordinary people, living and working in peace and contentment, not suffering from war and chaos, is already content, and not having to live in a dirty environment is even more happy. As soon as the primary sewer was built, the sentiment index immediately rose by 7 percentage points to 91 points.

Lu Yao inspected the newly added infrastructure buildings and came to the granary. Fifty huge and friendless, five-foot tall granaries made him feel refreshed.

The capacity of the premium grain silo is only 20,000 units. Fifty granaries are only one million units. With the development of the territory and the increasing population, this little bit of food and grass is far from enough. Before he speculated to lead the imperial army, and in the first city of China, one million units of grain and grass were not enough for the 100,000 army to eat for a few days. Of course, the large number of cavalry at that time was also one of the main reasons.

The capacity of the premium grain silo is as high as 100,000 units. Fifty granaries totaling five million units. It's still not enough for the future, but for now, it's enough to last a year.

Lu Yao looked at the huge granary standing in front of him, thought about it, and simply took precautions, built fifty primary granaries in one go, and then gradually upgraded to special granaries, making up one hundred special granaries, totaling 10 million units of grain and grass. With the current population growth rate of Xanadu City, this grain and grass is enough to guarantee about two years.

Don't panic when you have food.

This principle is not lagging behind in any era. The more abundant the grain and grass, the less likely it is to have problems in the development of the territory. The only problem is that it takes time to fill the granary. However, with money in hand, Trench Lu didn't pay attention to it at all.

After inspecting Xanadu City, Lu Yao returned to the Lord's Mansion and asked Jia Xu, Ding Yan and others to purchase grain and grass for emergencies, and then waited for the system to update with peace of mind, gearing up for the next opportunity.
