Fourteen days later.

It's rainy, and depending on the weather, I'm afraid there will be a few days of rain.

Cheng sent someone to retrieve the sweet potato and handed her the map with the re-marked geographical location.

"You give this map to Xiudong, and let her go to these places to investigate and find out all the people I mentioned."

Sweet Potato asked with some confusion: "Childe, don't you go in person?" ”

Cheng Liu looked at the light rain outside the window and said softly: "I can't leave here for the time being, and if there is news, I will leave as soon as possible." ”

Sweet potato nodded, and was about to go out when Cheng Liu suddenly spoke again.

"Wait, the first place to go is Yingchuan County."

Yingchuan County is the closest to Luoyang, and Xu Fu in history, which was later renamed Xu Shu, is from Yingchuan County.

Although the geographical location is not as superior as Luoyang, it has historically been the most prosperous place after the capital since the establishment of Yingchuan County.

Sweet potato nodded and went out with the map.

Cheng Liu was about to sit down when he heard Dian Wei's voice coming in from outside the courtyard.

"Lord, the garrison in Stone City has been empty recently, should we go directly?"

Cheng Liu looked at him with a look of poised to go, and said in a deep voice: "How many people?" ”

"There are only about 2,000 people, and we have enough soldiers and horses."

The location of Shicheng County is not easy to attack, but Dian Wei swears, and Cheng Liu doesn't have much to say, so he asks him to directly make a military order and take it down directly within three days.

Dian Wei went out in a hurry, after all, let him stay in Danyang County to train during this time, his hands were already itchy, and while it was raining now, Shicheng should not have too much attention, this time was the best time.

Cheng Liu sat down again, and there was a book of folds in front of the desk, which were all reports from some counties, and the most talked about was the problem of grain production, and of course, there was also the problem of stockpiling grain after the autumn.

Although there are many melons in the sky, they are not suitable for every place, and there is no way to make the irrigation equipment widely used in a short period of time, so thinking of these, Cheng Liu can only pin his hopes on taking Shicheng and bringing the water source there to the counties.

It wasn't until dusk approached that the sweet potatoes returned.

"I've already sent Xiudong out of the city, and I've also explained what should be explained, and when I came back, I found that someone was sneaking around near our county guard's mansion, looking at the pretend, it didn't seem to be our Central Plains people."

Hearing this, Cheng Liu immediately thought of the man he bumped into on the bridge before, and his clothes were also very different.

"Did you have someone to investigate?"

"I've already let Spring Butterfly follow, but maybe I'll lose it."

"Why?"

Cheng Liu asked a little strangely.

"There are only two of them, but their actions are very secretive, and they are gone."

Hearing this, Cheng Liu suddenly had a bad premonition.

"Where did they end up?"

"Shifang Street."

Shifang Street?

After coming out of the private school that day, I also saw them returning from Sifang Street to Shifang Street, where he had newly established a private school, and recently asked the people from the Yajian camp to go there more often, so as not to cause trouble.

But if these two people who acted secretively lived on Shifang Street, it was impossible for no one to find out.

"Go and bring me the plates that have recently entered the city."

Before entering the city, there will be soldiers or officials under the city gate to register routinely, such as where they are coming from, where they are going, what they are coming to do, doing business or visiting distant relatives, etc.

Sweet potato thought for a moment and asked, "Now?" ”

Cheng Liu didn't have time to explain, so he asked him to get it quickly.

It was about half an hour before the sweet potato returned with a few thick booklets.

"Here's a list of registrations for a few days to enter the city, take a look."

Cheng Liu immediately flipped through it, and there were records of outsiders leaving the city in the past three days, all of whom were Huns.

At this time, although there was no official war with the Xiongnu, it was already eyeing the tiger.

What's more, they didn't go to Luoyang City, but what did they do in Danyang County?

Cheng Liu hadn't figured it out yet, and the sweet potato suddenly slapped his head, as if he had thought of something.

"By the way, Childe, I thought about it, when you asked me to recruit those people that day, these two people also appeared, but I have forgotten a little now, whether it is them, maybe they are just similar clothes."

Cheng Liu was still checking the list, and after reading a few plates, he had already found a clue.

"There are not only two Huns who entered the city, they came in in a different identity, there are at least ten or more Huns in the city, but we rarely seem to meet them on the street."

Speaking of this, the sweet potato also nodded.

"That's right, I haven't seen any of these people on the street when I went out these days."

"So where will they hide? And, why are they hiding? ”

Cheng Liu was also very puzzled by this, they didn't hide information when they entered the city, I'm afraid it was useless to know that hiding information, so they simply changed their identities, such as after two people entered the city, they changed into a set of clothes in the city, and then went out of the city again, and then let the two Huns come in.

After this rotation, according to the list on the list, it can be guessed that there are at least five batches of people, almost every day, which will neither arouse their awareness nor easily reveal their identities.

"But he's really meticulous."

Sweet potatoes are already starting to worry at this point.

"Childe, Chundie went to chase after you, will something happen?"

Cheng Liu is not very sure, although Chundie's martial arts have improved recently, but he doesn't know how big these Huns' skills are, and they dare to mix in, I'm afraid they have some real kung fu.

After thinking about it, Cheng Liu still said: "You take Xia Cicada to go outside to investigate, remember, don't startle the snake, and don't cause panic." ”

Sweet potato nodded, didn't dare to delay any longer, and immediately went out.

The rain outside was still falling, and Cheng Liu's mind was also restless.

Another maid was called to make a pot of tea, and stood by the window restlessly waiting for news.

But after drinking a pot of tea, there was still no movement outside.

Just when Cheng Liu was completely impatient, the sweet potato came back with Xia Cicada.

"Did you find it?"

"I went to Shifang Street, and after I entered a pawnshop, I never came out again."

Pawnshop? There are two pawnshops on Shifang Street, one in the south and one in the north, which is just symmetrical.

"Which one are you going to?"

"The pawnshop in the south."

Xia Cicada answered.

The ditch that connects one of the square streets to the south is a busy city along the street, and there is no curfew yet, so I am afraid that there are still many people at this time.

"You stay in the mansion, stabilize anything first, and wait for me to come back."

Sweet Potato suddenly panicked, and hurriedly asked, "Childe, do you want to go out?" ”
