A group of naval fleets were fooled by Katrin for two days. Knowing that going on like this was not only a waste of time, but also a lot of manpower and material resources, all the major kingdoms and empires temporarily gave up.
Facing a city that can dive at any time and is surprisingly fast under the sea, they have nothing to do.
They also thought about letting soldiers who are good at diving dive into the sea to attack immediately after Katrin dived, but they found that they couldn't get close to Katrin at all.
Even though they wished to occupy Katrin right away, facing Katrin's powerful diving ability, they could only give up and wait for the opportunity to talk about it later.
The eastern part of the sacred sea finally returned to calm temporarily, and the pirates in the eastern sea couldn't help but breathe a sigh of relief.
Then the surviving pirate group discovered that at least half of the pirate groups in the eastern sea area had been raped, and now is a good time for development.
And not too far from the area where the Black Flag Pirates were active, Katrin floated quietly on the sea.
After this incident, Katrin's population was hit hard again. Most of the NPCs who had been stationed in Katrin before escaped from Katrin before the war started, and Katrin's population attributes fell to an extremely low point again.
But Chen Mo doesn't care, now is the time when Katrin really starts to develop.
Those who escaped from Katrin before will probably start to regret it now. After this incident, Katrin will soon be known to everyone on the Holy Continent.
After Katrin's system is perfected, once it is opened up, it will be overcrowded at will, and the population attributes can reach as many as you want.
During the two days when he was chased and fled at sea, there was not much he could do. Chen Mo only did one thing, which was to build a large library.
The books moved back from the city under the sea had not had time to deal with them before. Chen Mo simply built this library when he had time these two days.
After all, life at sea is no better than on land, and there are not many places to go. It will be much more convenient to have a library.
As for the establishment of the library, Enoch, Fatila, and Yuki all agreed very much.
With so many people wishing, Chen Mo naturally wanted to complete it immediately.
"Okay, it's finally done."
In Katlin’s city system, there is a special library management system. Chen Mo built a library, moved all the books into it, and made related settings on the library management system one by one. The system will prompt that the library has been established. .
"Master Adventurer, I have asked Tana to help adjust the urban diving system. After this adjustment, the energy consumption of the system will be greatly reduced. Of course, if you continue to move quickly in the deep sea, the energy consumption will still be very high. Huge, but just standing still, the energy consumption is lower than that of the original underwater city."
When Chen Mo was celebrating the establishment of the library, Otto and Tana also came to report.
The city diving system is quite complicated, and thanks to Otto, otherwise Chen Mo would be useless even if he got the city diving system.
Although the city diving system could be used before, it was installed on Katlin in a hurry. Naturally, there were many problems in the haste.
And these two days, after continuous testing, Otto finally adjusted the city diving system to a fairly perfect state.
Chen Mo has been using the city diving system continuously for the past two days. In addition to making those kingdoms and empires give up and helping the Black Flag Pirates get rid of their competitors, it also has the purpose of testing and adjusting the city diving system.
"very good."
Chen Mo nodded. The urban diving system is no problem. With the sky tree, the urban flight system can also be used, but there are not many functions at the moment.
System prompt: The city has both the urban diving system and the urban flight system, meeting the conditions 2…
System prompt: Item inspection... Possess a qualification certificate!
System prompt: Identity detection... not an assessment target!
System prompt: meet the special condition 3, the special development route is opened...
When Chen Mo turned on the city diving system and the city flight system, made some confirmations, and made some adjustments, several system prompts sounded one after another.
Looking at these system prompts, Chen Mo couldn't help but hesitate.
System prompt: Due to special conditions, the territory you own has evolved from an ordinary city territory to a strategic city. Now you have two routes to choose from.
Route 1: Ordinary player route. Under this route, every time the strategic city upgrades to a level, you can get a lot of rewards from the system, and the city and you will become stronger and stronger.
Route 2: Special development route. If you have a question about the game and want to know the answer, this is the route to go. Under this route, if you can develop the strategic city to the highest level and achieve the highest goal, the system will answer all your questions. But under this route, the development of strategic cities will no longer receive systematic assistance, but correspondingly, you can get some helpful tips for development.
Note that once a route is selected, it cannot be changed.
Follow-up system prompts appeared one after another, it was fine for Chen Mo not to look at it, but after looking at it, his pupils shrank involuntarily.
"Ha ha ha ha!"
Looking at the system prompt, Chen Mo couldn't help laughing wildly after realizing it.
Entering the game, playing until now, his strength is close to the strongest person in the game, but his understanding of the game is not as good as the core figure in a consortium.
But now, after Katlin changed from an ordinary territory to a strategic city, the route choice that appeared gave him a chance to know everything!
He doesn't need to ask others for help, as long as he works hard to develop Katrin, he can learn everything he wants to know!
For this game, Chen Mo has too many things to figure out!
"Choose route two!"
Without even thinking about it, Chen Mo made a decisive choice.
At the beginning of developing Katrin, he was interested in those gold coin options, but right now, gold coins are not very meaningful to him, and developing Katrin gives him the most rewards, so he doesn't value it too much.
Route 2 has no system rewards, and it may be financially tight when it develops in the future, but he has plenty of ways to make money.
System prompt: Route 2... Select to confirm!
System prompt: The city is officially changed to a primary strategic city, the city system has changed, and the next level is an intermediate strategic city, please confirm the upgrade conditions in the city system!
When the system prompt sounded, Chen Mo immediately opened the city system, and after a look, he found that the system had indeed undergone tremendous changes.
Previously, Katrin needed attributes such as population, finance, and technology to upgrade, but now those attributes have disappeared, and the upgrade conditions are completely different.
Intermediate strategic city upgrade conditions:
Intermediate City Diving System—100% complete.
Intermediate Urban Flight System - 70% completion.
Intermediate Strategic Library - 100% completion (Conditions: There are enough books about magic and technology in the library)
Intermediate Defense System—100% complete.
Intermediate Talent Reserve—Completion 30% (Conditions for achievement: at least 3 intermediate occupations such as pharmacy, tailor, blacksmith, etc.)
Intermediate Skilled Worker—Completion 0% (Accomplishment condition: the development of a strategic city is inseparable from skilled workers. Many facilities require workers with skilled skills to complete. At least 10 skilled workers are required.)
…
Unlike the upgrade of ordinary territories, the upgrade of strategic cities is much more complicated at once.
However, Katrin's foundation is obviously good. Although there are many upgrade conditions, Katrin has actually met many of the conditions, and she is not too far away from being upgraded to a mid-level strategic city.
Chen Mo glanced at the upgrade of the strategic city level, the primary level is followed by intermediate level, advanced level, and the highest level.
Right now, it is not far away from being promoted to the intermediate level, only two levels away, and it will be able to rise to the highest level.
After reaching the highest level, he can know everything.
Seeing this, Chen Mo immediately regained his spirits.
However, after calming down for a while, Chen Mo also knew that it would definitely not be easy to rise to the highest level.
Right now, the conditions for upgrading from beginner to intermediate level are quite complicated. If he wants to be promoted to the highest level, he needs to do a lot of things.
There is no rush to upgrade, you have to take your time.
However, to upgrade the city to the middle level first, it seems that as long as you find a few more talents, and even find 10 exquisite workers, the city can be upgraded. Of course, Chen Mo wants to upgrade to the middle level strategic city first, and confirm the upgrade conditions for the next level , so that you can prepare for the upgrade in advance.
