The four of Lu Shuang came to a small dark room to talk, and it was too late to go to the big conference room for a grand meeting, but the enclosed space gave people the feeling of discussing important matters or top-secret information.

"Lord, I wonder what you are doing with us?" Cao Lao had a higher status among the three and was the first to speak.

"I'm coming to you today to discuss upgrading the town." Lu Shuang glanced around at the three of them and continued: "Many towns in Feitian Town, King Kong Town, Tiefan Town, and other territories have already met the conditions for upgrading small towns, but they have always shown that they cannot be upgraded, which makes me very confused. Cheng Hui and Chen Lang, the two of you used to be the owners of the third-level cottage, that is, the owners of the small city, I want to ask how you were upgraded to a small city in the first place? ”

Cheng Hui and Chen Lang knew each other's identities, and this time they asked them to come together, and the two had a vague premonition that it was related to their former identities.

The two glanced at each other, and Lu Shuang saw that he didn't speak, so he added: "It's not a big deal, the two generals just need to say what they know, don't worry too much."

"Yes, my lord." Not long after Chen Lang joined Feitian Town, he chose to let Cheng Hui speak first, Cheng Hui thought for a while, and said, "Let's start from the beginning." Maybe the lord doesn't know, building a cottage is similar to building a village, the only difference is that the rogues don't need a village order to build a village, but because of this, there will be a lot less things. Therefore, the conditions for upgrading from a second-level cottage to a third-level cottage are exactly the same as those for upgrading a township to a small town, in addition to the building, resources, money, and population on the surface to meet the requirements, there must also be an item, which can be said to be a necessity. ”

"Necessities? We can't upgrade it all the time, or we don't have it? Lu Shuang asked.

"That's right, this necessity is called the heart of the city, and it is necessary to upgrade small cities, heavy cities, and even capital cities and royal cities." Cheng Hui is very determined.

"The heart of the city." Lu Shuang recited it silently in her heart and asked the key: "Since the heart of this city is so important, how can it be obtained?" Cheng Hui: Do you know where to find the heart of the city? Or how did you get it in the first place? ”

"This, the heart of the city must have appeared in the ancient ruins, according to legend, the ancient period of the Yellow Emperor Chiyou War, and then to the three emperors of Yao Shunyu, and even when the King of Qin swept **, the ancient ruins will be left, and the heart of the city comes from these ruins. Ancient ruins cannot be said to be known by people, but they can be as big as ancient battlefields or imperial capital ruins, and as small as a tree."

Cheng Hui knew a lot, and gushed endlessly: "Because the heart of the city is the key to upgrading the small city, some people think that it is a good luck, and some tribes will choose to settle down in some ancient ruins and guard the heart of the city for generations, or directly put it in the temple for incense worship." The Fog Shadow City built by the last general at that time was stolen from them. ”

Speaking of this, Cheng Hui touched his nose embarrassedly, afraid that his previous deeds would make Lu Shuang feel disgusted.

"So you say, if you want to get the heart of the city, you have to snatch it from these tribes?" Lu Shuang advocates peace and is a little resistant to robbing others of their beliefs.

"Back to the lord, this ancient ruin may not always be enshrined, the last general was guided by the main god before, and found a city heart in an ancient ruin that no one is around. And I heard the older elders in the city mention that most of the ancient ruins are left in very uninhabited places, like the heart of the city that has been found by the tribesmen. Chen Lang expressed his opinion at this time.

Lu Shuang looked at Cheng Hui and then at Chen Lang, although the experiences of the two are quite different, but there is a lot of information that can be obtained by integration.

First of all, it is the origin of the heart of the city, Cheng Hui introduced that it comes from ancient ruins, but from ancient times to the Eastern Han Dynasty, there is also a history of more than two or three thousand years, in addition to those places recorded in historical records, the ghost knows where the "celebrities" at that time will leave relics. And the more famous the ancient ruins, the more likely they are to have been exploited; On the other hand, it is possible that a person secretly traveled to a place and left behind a ruin, most likely undiscovered. But this is also the hardest, the map is so big, it happens to be too difficult to find a small place.

The second is that some NPC tribes may have the heart of the city, Lu Shuang noticed that Cheng Hui said that he stole it instead of robbing it, with the strength of his king-level generals at that time, he was a well-known general in a county town, but he wanted to steal it from the tribe, and the strength of the tribe should not be bad. Lu Shuang didn't want to use this method, in case the tribe he encountered was a hard stone, and stealing chickens would not outweigh the gains.

Finally, there should be a lot of ancient ruins, and since Chen Lang can find the heart of the city under the guidance of the system, there will definitely be a lot of them for players. In the end, it is still a game, and the system can increase the difficulty of obtaining the heart of the city, that is, the difficulty of building a city, but it is always left to the player.

"Elder Cao, two generals, do you have any suggestions for finding the heart of the city? If we can find it one step earlier, the strength of our territory will be one step higher. "Knowing one thing and doing one thing are two completely different concepts, and Lu Shuang wants to hear useful advice from them.

"My lord, I think we can send someone to search for those recorded ruins, although some may have been taken, but it is good to pick up a few in case I can miss a few." Cao Lao proceeded from maximizing interests, taking into account both, and analyzed: "As for those ancient ruins that no one cares about, you can send soldiers to each state to search, and once you find it, you can immediately take it back, and first get the title of the first city in the world."

"What Elder Cao said is that in this way, those soldiers who go out to find the heart of the city will be treated well." Lu Shuang nodded.

"My lord, in fact, when the last general went to the ancient ruins to obtain the heart of the city, there was a limit, and it took a lot of effort for the last general to obtain the heart of the city from that ruin. In addition, some ancient ruins are ancient buildings, which are easy to find; But there are also those that have no obvious characteristics and are not easy to find, but one thing is for sure, where there is the heart of the city, there will be auspicious atmosphere, and people will continue to maintain a good state in the vicinity. Chen Lang missed a point.

"Then General Chen thinks that with the force we have now, can we break the restrictions and gain the heart of the city?" Lu Shuang asked for more details.

"It's hard to say, if it's the ruin that the last general encounters, it must be more than enough. However, different ruins have different restrictions, and the exact difficulty is not understood, but the higher the difficulty, the higher the level of the Heart of the City. Chen Lang replied.

"Okay, since there is still a limit, then let the soldiers sent to look for these ruins, find the marked coordinates, and then we will go there together."

"That's very good."

Since Cheng Hui and Chen Lang's methods of obtaining the heart of the city are irreproducible, Lu Shuang can only start from the most basic, first send people to search everywhere, find it and then consider the next step.

The initial plan was for each county to send 20 to 30 soldiers in charge of a carpet search, focusing on those places that were chronicled or sparsely populated. About 500 soldiers are in charge of a state, and each team demarcates the county of responsibility, and after searching this county, it goes to another county until the mission is completed.

About 500 eighth-order soldiers were sent to each state at the same time, giving priority to searching the four prefectures of Jiaozhou, Yizhou, Liangzhou and Sili, and reporting back from the teleportation array as soon as there was intelligence. This has the advantage of being able to concentrate on the search of key areas more quickly and, if you are lucky, you can find several ancient ruins. There were no samples of ancient ruins or auspicious qi in Feitian Town, so the soldiers could only be sent to detect it themselves.

Because there is no charge for taking the teleportation array in the Fog Shadow City to other system cities, you only need to calculate the cost of living outside, dry food, and the cost of teleporting back to the soldiers. The two thousand eighth-order soldiers need to pay a lot of money for them, but since August, Lu Shuang has handed over several batches of equipment to Hu, and he has earned tens of thousands of gold before and after, and he can still afford this part of the money.
