At the same time as receiving the system prompt, Yang Rui also got a virtual map, on which each county in Yang Rui's jurisdiction is marked with two options: open and non-open, and there are five percent of the city quota that can be opened without insurance, and private territory can be unconditionally open or not.

In this way, Yang Rui has nothing to say, the number of counties under his jurisdiction now exceeds 100, and there can be 6 cities that choose not to open, and Dashan City, as Yang Rui's self-built territory, is unconditionally not open.

Therefore, in addition to the more important 6 cities of Linzi City, Pingyuan City, Puyang City, Changyi City, Fenggao City and Juancheng, Yang Rui directly chose to open all the other cities, so naturally he did not have to pay any security to the system.

As for Dashan City, if it is open to the player communication system, there will definitely be many players who will come over to take a look, and the income should not be less, but Yang Rui gave up this idea after hesitating for a while, no matter when, Dashan City is Yang Rui's last foundation, and he naturally will not let people know too much easily.

Although player communication can only be used as a visitor or tourist, and cannot engage in battles or other regular game activities, it will basically not affect the normal state of the region, but there is no way to prevent the spread of information to the outside world.

What's more, there are also things involving Shangmo City, Taishan Realm, and even Ezo Teleportation Array in Dashan City, and it is not without the possibility of being exposed, just from this layer, Yang Rui gave up his intention to show it in front of other players.

"Huo!"

Yang Rui quickly finished his selection, and his energy returned to the 19th floor of the Civilization Tower where he was currently located, and rushed towards the few remaining Tier 2 mutant bird colony nests......

"System Prompt: Congratulations to the player, Blazing Sun. Successfully break through the 20th floor of the Three Kingdoms Civilization Regional Civilization Tower. Gain 200 reputation points. 200 gold coins, and the right to draw silver items 2 times. ”

After more than half an hour, Yang Rui was already overwhelmed, and he cleared the 20th floor of the Tower of Civilization, and the system prompt for clearing the reward came again.

And this time, from the 11th to the 20th floor of the Tower of Civilization, Yang Rui only spent most of the day in total, which was even a third shorter than when he cleared the first 10 floors.

It's no wonder that the 11th to 20th floors of the Tower of Civilization are almost a replica of the previous 10 floors. It's just that the size of the map and the number of monsters have changed slightly, but in front of Yang Rui, the difference between the 1st and 2nd orders is almost negligible.

Not only is the situation very similar to the two tenths, even the law of the collapse of civilization marks is extremely consistent, the 15th layer level itself has plummeted a civilization mark, the 14th and 19th floors of the bird's nest have also plummeted civilization marks, and the 20th floor is still the territory, several gates and council rooms have collapsed 3 civilization marks......

Yang Rui has been paying attention to the collection of civilization imprints, and within these 10 layers, Yang Rui still collected all the civilization imprints into his bag, and combined them again into 10 booklets, so far Yang Rui has obtained 1 prologue including the "Classic of Mountains and Seas * True Records". The rest of the mountain scriptures are 5 chapters and overseas scriptures are 5 chapters. There are 5 chapters in the Sea and 4 chapters in the Great Wilderness Scripture.

"System Prompt: Dear player Lieyang, you have collected all the prologues and 20 texts of the "Classic of Mountains and Seas * True Records", and combined them into the complete version of "The Classic of Mountains and Seas * True Records", congratulations on obtaining the "Classic of Mountains and Seas * True Records", and comprehend that you will obtain the clues of the world-class main quest of the origin of civilization!"

When Yang Rui stepped into the passage on the 20th floor of the Tower of Civilization and entered the second virtual supply level, two consecutive system prompts came one after another, the front was about the customs clearance reward, and the latter was a reminder to obtain the "Classic of Mountains and Seas* True Record".

"System Announcement: Congratulations to the Three Kingdoms Civilization Region Blazing Sun, obtaining the complete version of the "Classic of Mountains and Seas * True Record" in the Tower of Civilization, and a special reward of 1000 prestige points."

When Yang Rui was thinking about how the "Classic of Mountains and Seas* True Record" and the world-class main quest of the origin of civilization would be involved, a civilization-wide system announcement was released again, and it was announced three times in a row.

Although there are some vague words in this system announcement, there will definitely be no system announcement in the whole civilization region for ordinary events, and Yang Rui was also surprised by this announcement.

But it's not surprising if you think about it carefully, "The Classic of Mountains and Seas* True Record" involves the world-class main quest of the origin of civilization, and it is very normal to make announcements in the whole civilization region, and after the latest adjustment of the system, the world-class main quest has been put on the agenda.

Yang Rui has also obtained the origin of the Qiang people, the origin of the Xiongnu and other related tasks, both tasks have not been completely completed, intuitively or with the origin of civilization world-class main quest has some connection, Yang Rui can't help but look at the two tasks that have been shelved in the task bar for a long time.

At this time, Yang Rui cleared the first 20 floors of the Tower of Civilization, and almost two game days had passed, and Yang Rui's physical strength and energy consumption was not small.

By the time the hourglass marked by the system reversed, two hours had passed, and Yang Rui looked at the thick book of "The Classic of Mountains and Seas* True Records" in his hand, but he still had no clue, and during this period, Yang Rui had been checking this newly acquired book.

"System Prompt: Dear player Blazing Sun, you have entered the 21st floor of the Tower of Civilization, and you need to obtain 40 Civilizations Marks within this level to be eligible to enter the 22nd floor of the Tower of Civilization......"

As soon as the time limit of the system arrived, Yang Rui was directly and forcibly teleported to the 21st floor of the Tower of Civilization to continue the challenge of the Tower of Civilization.

I don't know what the reason is, Yang Rui looked at the "Classic of Mountains and Seas* True Records" left and right for a while, but he was never allowed to enter the door, and he did not get any clues about the world-class mission.

And not only that, it is clear that "The Classic of Mountains and Seas * True Record" is already in a state of completion, but Yang Rui only knows that it is generally introducing various mountains, rivers, people, monsters and the like, but every time it comes to the key point, the record of "The Classic of Mountains and Seas * True Record" is that kind of image and graphic mode, and Yang Rui can't see it at all after several attempts.

Very similar to the previous reaction, every time the image appeared in the graphic mode, Yang Rui felt in a trance, as if he was about to be completely attracted and unable to extricate himself, so that Yang Rui had to give up several times halfway, and had to wait for the future to study slowly.

"Huo!"

Yang Rui rushed to the 21st floor of the Tower of Civilization, the situation in the map still did not change very much, and the monster rank was upgraded by 1 level, all of them reached the 3rd level, and the map area also increased a little, and the rest of the situation was not much different from the previous 20 layers.
