A group of naval fleets were tricked by Catherin for two days, and after knowing that this was not only a waste of time, but also a waste of manpower and material resources, the major kingdoms and empires gave up for the time being. Pen, fun, pavilion www. biquge。 info

Faced with a city that could dive at any time, and go down to the bottom of the ocean at an incredible speed, there was nothing they could do.

They also thought about letting the soldiers who were good at diving dive into the sea to attack immediately after Katrin dived, but found that they couldn't get close to Katrin at all.

Although they wanted to capture Katrin immediately, they had no choice but to give up in the face of Katrin's strong diving ability, and wait until they had the opportunity to talk about it later.

The eastern part of the sacred sea area has finally returned to calm for the time being, and the pirates in the eastern sea can't help but breathe a sigh of relief.

Then the surviving pirate group found that at least half of the pirate group in the eastern seas had been killed, and now was the time for development.

Not too far from the Black Flag Pirate Band's area of activity, Catelyn floated silently on the surface of the sea.

After this incident, Katerin's population was hit hard again, and eighty percent of the NPCs that were stationed in Catlyn before the war escaped from Catlin, and Catlin's population attributes fell to a very low point.

But Chen Mo didn't care, now was the time when Katrin really began to develop.

The people who escaped from Catlyn before are probably beginning to regret it now, and after this incident, Catlyn will soon be known to everyone on the Holy Continent.

After Katrin's system is perfected, it will be overcrowded as soon as it opens up a little, and the population attribute can reach as much as you want.

In the two days that he was chased and escaped at sea, there was not much he could do, Chen Mo only did one thing, that is, to build a big library.

The books brought back from the underwater city have not had time to deal with them before, so I have time in the past two days. Chen Mo simply built this library.

After all, the days at sea are not as good as those on land, there are not many places to go, and it will be much more convenient to have a library.

As for the establishment of the library, Enoch, Fatila, and Yuki are all very much in agreement.

With so many people hoping that Chen Mo would naturally complete it as soon as possible.

"Alright. It's finally done. ”

In Katrin's urban system, there is a special library management system, Chen Mo built a library, moved all the books into it, and then made relevant settings on the library management system, and the system prompted that the library had been established.

"Adventurer, I have asked Tana to help adjust the urban diving system, and 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 huge, but it will only stand still, and the energy consumption will be even 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 urban diving system is quite complicated, and fortunately Otto is there, otherwise Chen Mo would be useless even if he got the urban diving system.

The City Dive System had been able to be used before, but it had been hastily installed on Katlin. In a hurry, there are naturally many problems.

And these two days. After a lot of testing, Otto finally got the city diving system in perfect condition.

Chen Mo has been using the urban diving system for the past two days, in addition to letting those kingdoms and empires die and help the Black Flag pirate group get rid of competitors, it also has the purpose of testing and adjusting the urban diving system.

"Good."

Chen Mo nodded, the city diving system is no problem, there is a sky tree. The urban flight system can also be used, but there are not many functions at the moment.

System Tips: The city has both the urban diving system and the urban flight system, and the condition is 2......

System Prompt: Item Detection ...... Proof of Eligibility!

System prompt: Identity detection...... Non-assessment objectives!

System prompt: If special condition 3 is met, the special development route will be opened......

When Chen Mo turned on the city diving system and the city flight system, he made a confirmation. After some adjustments, several system prompts sounded one after another.

Chen Mo looked at these system prompts and couldn't help but be surprised.

System Prompt: The territory you own, due to special conditions, has evolved from an ordinary city territory to a strategic city, and now you have two route options.

Route 1: Normal Player Route. Under this route, each level of the strategic city will give you a large number of rewards from the system, and the city and you will become stronger and stronger.

Route 2: Special development route. If you have questions about the game and want to know the answers, you can choose this route. 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. However, under this route, the development of strategic cities will no longer receive systematic assistance, but accordingly, you will be able to get some tips to help them develop.

Please note that once the route is selected, it cannot be changed.

Follow-up system prompts appeared one after another, Chen Mo didn't look at it, but after a look, his pupils couldn't help shrinking.

"Hahahaha!"

Looking at this system prompt, Chen Mo couldn't help but laugh wildly after he reacted.

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 Catlyn changed from an ordinary territory to a strategic city, the route choice that appeared gave him a chance to learn everything!

He doesn't need to ask for help, he just needs to work hard to develop Katrin on his own, and he can learn everything he wants to know!

Chen Mo has too many things to figure out about this game!

"Choose Route 2!"

Without thinking about it, Chen Mo made a decisive choice.

At the beginning, he was interested in those gold coin options, but now, gold coins don't mean much to him, and he doesn't value them too much.

Route 2 has no system rewards, and in the future, it may be financially tight, but he has a way to make money.

System Prompt: Route 2...... Select Confirm!

System Tips: 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 at a glance, he found that the system had indeed changed dramatically.

In the past, Catlyn was upgraded, and the attributes such as population, finance, and technology were required, but now those attributes have disappeared, and the upgrade conditions are completely different.

Intermediate strategic city upgrade conditions:

Intermediate City Dive System - 100% Completion.

Intermediate Urban Flight System - 70% completion.

Intermediate Strategic Library - 100% completion (Requirements: Enough books on magic and technology in the library)

Intermediate Defense System - 100% Completion.

Intermediate Talent Reserve - 30% Completion (Achievement Requirements: Potions, Tailors, Blacksmiths...... and other intermediate occupations must have at least 3. ）

Intermediate Skilled Workers - 0% Completion (Achievement Condition: The development of strategic cities is inseparable from Skilled Workers, many facilities require skilled workers to complete, at least 10 Skilled Workers.) ）

……

Unlike the upgrade of ordinary territories, the upgrade of strategic cities is suddenly much more complicated.

However, Katrin's foundation is obviously good, and although there are many conditions for upgrading, Katrin has actually achieved many conditions, and it is not too far from being upgraded to a mid-level strategic city.

Chen Mo glanced at the improvement of the level of the strategic city, and after the beginner, there was the intermediate, advanced, and highest level.

Right now, it's not far from being promoted to the intermediate level, and it's only two levels away from being able to reach the highest level.

Once he reaches the highest level, he knows everything.

Seeing this, Chen Mo suddenly came to his senses.

However, after calming down a little, Chen Mo also knew that it would definitely not be easy to rise to the highest level.

At present, the conditions for upgrading from primary to intermediate are quite complicated, and if he wants to be promoted to the highest level, he needs to do a lot of things.

The escalation is in a hurry, you have to take your time.

However, first upgrade the city to the intermediate level, it seems that as long as you find a few more talents, and there are 10 exquisite workers, the city can be upgraded, Chen Mo of course wants to upgrade to the intermediate strategic city first, confirm the upgrade conditions of the next level, and prepare for the upgrade in advance.
