At night in Cangyan City, the wind blew, and the cold became heavier.

But Cangyan City is so lively.

Most areas outside Fugui Lane began to fire again, and they were rising and falling, and the Fugui Lane was also noisy. Some mansions that had been sealed by officers and soldiers for many days returned to their freedom, and they hung large lanterns at the door, red, while others were even more lively.

There were the crying sounds of women, girls and children, and the sound of officers and soldiers entering and leaving the cabinets. Boxes of property were carried onto the frame and transported to the treasury government office, as if they would never be moved cleanly.

The wealth in Fugui Lane can be seen.

Luo Mansion is the quietest alley in this alley. Once the mansion is closed, everything outside has nothing to do with it.

It was only the next morning that Luo Mansion woke up again, and the front and back yards were busy. When the sun rose slightly to the ground, a convoy of 100 bloody riders guarded by a sequel of 100 people drove out of the gate of Luo Mansion.

There were only two carriages, one was still driven by an old coachman, sitting in Luochuan, Siqi and the young woman with a cold face forever.

The other car was driven by a vicious Taoist priest Qin Wansong, among which was a square-faced Taoist priest Chang Wuxi.

The convoy drove out of Fugui Lane and headed west. People knelt on both sides of the street along the way.

The convoy was driving slowly. When it was a street and alley, another rider joined the convoy after inspection. It was Chen Shu, the deputy general manager who Luochuan had rescued in Shuangjing Town. At first, he just followed the end of the team, and then Luochuan called to the side of the carriage and asked, "How is the injury?"

Chen Shu bowed on the horse, and then felt that it was a bit inappropriate for him to be in a higher position than the county guard, so he turned over and got off the horse and led the horse to the carriage. "If you return to the county guard, Bei Zhi's injury has healed. I went back to the yamen yesterday and brought out the Cangyan topographic map drawn by Bei Zhi." He untied a long bamboo tube behind him and handed it to Luochuan. "This map is made of mountains and rivers as the bones, towns and villages as the meat, and roads are divided into plow fields. The real part of the picture is the plow fields that have been measured and recorded into the treasury. The position of the dotted line or the dotted line is the wasteland that Bei Zhi thought could be reclaimed as fields."

Luo Chuan took the bamboo tube and expanded the map. The map was very large, and it took almost half of the space of the car. However, compared with the map that he had seen in his previous life, the picture in front of him still seemed crude. However, considering the actual situation of this world, looking at the mortal body of the man in front of him, the effort spent behind this map was simply unimaginable. "I heard from the county magistrate that there was a drawing of arable land in the Siongfu government office, why did it take so much effort to re-draw this picture?"

"When I returned to the county, there are indeed drawings of cultivated land in the Siongfu government office, but they are only scattered, either centered on one city or centered on one town. Due to the different drawing scores, the drawings are difficult to splice and use. There are many duplications or vacant ones, so it is difficult to show the full picture of Cangfu government office clearly. It is not conducive to the subsequent officials of the Siongfu government office to understand the accurate situation in various places," Chen Shu looked at Luo Chuan and said seriously. "When I first entered the Siongfu government office, I encountered this problem. So I took advantage of the opportunity that the Siongfu government office had to go deep into various places to check farming, repeatedly verify the surveying and mapping, combined with the existing map of the Siongfu government office itself, and after drawing multiple pictures, it finally became this picture. After several years, when I followed this picture and left the city, I repeatedly verify that there would be no big error."

Luo Chuan nodded, and Siqi also stared at the map with curiosity and searched for the place he had walked through. The young woman who was often silent in the corner of the carriage opened her mouth, "This picture is not much different from the Cangyan land in the map of Cangyan Mountain. Except for the subtle differences in the trends of rivers and mountains, the locations of the cities and villages are basically the same."

"Oh?" Luo Chuan looked at the young woman in surprise and said, "Is there a fully-painted map of Lijun in Cangyan Sword Sect?"

The young female road shook her head, "It's not Lijun, but the entire southwestern Hanzhou."

Luo Chuan's eyes lit up suddenly. Just as he was about to say something, he was choked back by the young woman who guessed that he was thinking. "There is only one copy of the Cangyan Sword Sect, and it is hung in the master's room. Ordinary people can't see even the disciples of the Cangyan Sword Sect."

Luo Chuan looked down at the Cangyan map that was crossed in the carriage, and after a while, he pointed to a place on the map and asked, "Then did Luo River change its route from here and pour it into the Cangyan Mountains?"

Chen Shu tiptoed to the window of Luochuan's carriage and looked in, "Yes, it's not entirely right to say that it's a diversion. In fact, it's a diversion of the Luo River. Originally, the Luo River turned west to the near Cangyan Mountains, and went to the current Xiluo River Valley. It split and merged in that wilderness and finally merged into the Cangjiang River. After an earthquake more than ten years ago, the Luo River broke out a road in this diversion area. Eight out of ten of the rivers rushed eastward into the Cangyan Mountains, and then flowed southward into the Cangjiang River. Bei Zhi has seen it there many times. The new river channel seems to be deeper, especially after entering the Cangyan Mountains canyon. On the contrary, the original river channel is now mostly dry, but there are still some water branches flowing through it. Because the surrounding land quality is still very high."

"Has the Luo River diverted has happened in history?" Luochuan asked with a frown, "I heard from the county magistrate that there are many flood hazards in the lower reaches of the Luo River during the rainy season in Cangyan area. What's the matter now?"

"Beizhi once checked the documentary records of the Siongfu Office. There has been no recorded diversion in the Luo River in history. As for the rainy season floods, some areas of the lower reaches of the Luo River still occur from time to time. However, because of this diversion, both the frequency and degree of flooding are much weaker than in the old year," Chen Shu struggled to enter the carriage and clicked on several locations on the map. "These river troughs are shallower, but I talked with some local elderly people to know that the current water level of the river is shallower than before the Luo River diversion. If you can have the energy to build a little embankment along the low part of the river trough in the future, the flood may be cured."

"Things have to be done one by one. The river embankment is not a trivial matter. Now it is winter, and secondly, it is time to wait for Ze Yan to free up his hands," Luo Chuan asked, still pointing his finger at the position of the Luo River diversion, "What I am worried about is whether this place where the Luo River diversion will be changed back."

"This is really not a big deal, but it has been more than ten years since the Luo River has been redirected. There is no sign of redirecting again," Chen Shu frowned and pondered, saying, "The Bei Zhi has thought about this problem, but after checking it many times, he still feels that the possibility is not high. First of all, Luo River is a trend from north to south. Originally, it was just blocked by the Cangyan Mountains. Now, I have found a path between the mountains, which is more likely than going west than going west.

It is naturally smoother. Secondly, the rough exploration of Beizhi found that the terrain east of the Luo River diversion area was indeed slightly lower. However, the river water could not overflow the river trough before, otherwise the mountain to the east would indeed be connected to the water flowing to the lower part. Judging from the current situation, unless the mainstream after the diversion was completely blocked, the river water would flow back into the Naxiluo River Valley in large quantities. Otherwise, even if the diversion was changed again, it would still be necessary to go to the Cangyan Mountains."

"That's really a natural choice that has benefits but no harm, but..." Luo Chuan looked down at the map and murmured, "It's really such a coincidence..."
