Seeing that Chen Sheng was looking at the map and fell into deep thought, Meng Yi and Fusu were not in a hurry, and watched Chen Sheng's hand on the map very calmly.

Chen Sheng's brows flickered, and he said after a while: "My lord, I don't know if you have discovered the geographical features of Surabaya County. ”

Meng Yi didn't understand why Chen Sheng had this question, but then nodded, pointed to the vertical and horizontal rivers on the map and said: "Surabaya County, as the name suggests, has many river networks here, which is the biggest feature. ”

Chen Sheng smiled and said: "Yes, from Surabaya through the Huai River, the river network extends in all directions, you see, Xiangxian to Pengcheng, just a few hundred miles, there are two rivers Jushui and Surabaya, flowing through the Huai River, the river network is vertical and horizontal, you can go south, through Jiujiang County, Hengshan County and Changsha County. ”

"Yes, it does." Meng Yi raised his eyebrows, his heart moved, and said, "Do you suspect that these grains and grasses started from Surabaya and were transferred to the river?" ”

"Probably so." Chen Sheng nodded and asked: "Jianghuai will not freeze the river surface in winter, the river must be unimpeded, I wonder if the empire has monitored the river transportation for several months?" ”

Meng Yi's face suddenly became ugly. But Chen Sheng can also understand that in this era, shipping is not particularly developed, so it is very normal for the government to relax the monitoring of river transportation.

"Only the Bajun Ling family has such a huge transport fleet." Meng Yi drew inferences from each other and gritted his teeth and said. Ba County is located in the middle of nowhere, surrounded by lofty mountains, and caravans are transported by the Yangtze River. The Ling family, which has been operating in Ba County for many years, naturally has a fleet with super transportation capacity. General Yang ordered a thorough investigation of whether there had been a large number of ships coming and going to Surabaya County in recent months! ”

"Yes!" Yang Duanhe, the county guard who was standing on the side, heard Meng Yi's words and immediately walked out.

"Fusu, immediately write to the emperor, and ask the imperial court to immediately investigate the movements of the fleet of the Bajun Ling family for several months, and ask for the most accurate road map!"

"Yes!" Fusu also replied loudly. Judging from this scene, Chen Sheng knew that the noble eldest son Fusu was just here to help. This also made Chen Sheng breathe a sigh of relief in his heart, Fu Su is wise and wise, and his age is too young, I am afraid that he will not be able to cope with such a complicated matter.

However, judging from Fusu's reaction, Chen Sheng can see more things, that is, Fusu's attitude towards Meng Yi. From this point, it can be found that the personal relationship between the two is not shallow. With his previous memories and the teachings of his teacher, he understood what this meant.

"What are their plans to send grain to the south?" Meng Yi saw Chen Sheng's slightly distracted appearance, and couldn't help but ask. Chen Sheng just looked at the map and found a very important clue, and he inevitably looked a little higher at Chen Sheng in his heart.

Chen Sheng took a breath of cold air and said embarrassedly: "This is difficult to guess. ”

Meng Yi also nodded, it was already remarkable that Chen Sheng could think of this. However, Chen Sheng suddenly thought of something, his heart sank, and he raised his head and asked: "My lord, I heard that the army of the Imperial Southern Expedition is divided into five routes and is advancing towards Lingnan, but I don't know what the specific route is?" ”

Seeing that Chen Sheng asked about the military movements of the empire, Meng Yi pondered for a moment, pointed his hand lightly on the map, drew it, and said: "According to the plan formulated by the emperor and the generals, the movement of the five-way army is like this, starting from Qianzhong County, Changsha County, Jiujiang County, and Huiji County, all the way to the ridge of the city, all the way to the fortress of Jiuzhi, all the way to the capital of Panyu, all the way to the boundary of the southern wilderness, all the way to dry up the remaining water. ”

Chen Sheng was a little confused about the place names that Meng Yi had told, and he knew very well that these names were not quite the same as he understood. But comparing the map in his memory with the direction of Meng Yi's finger, he quickly figured out the direction of the Qin army's battle. I understood it in my own words.

According to Chen Sheng's understanding, the military dynamics of the Five Route Army from east to west are as follows: all the way from Jiangxi to the east, attacking Dongou and Fujian and Guangdong; All the way from Nanchang in later generations, over the Great Yuling, into northern Guangdong; All the way from Changsha, Hunan, through the riding Tianling directly hit Panyu; All the way through the Mengzhu Ridge to attack Guangxi Hexian, all the way through the Yuecheng Ridge to attack Guangxi Guilin.

The five-way army, 100,000 all the way, a total of 500,000 people. In front of them were the endless five mountains and the lack of grain and grass in the rear, and their hardships could be imagined. Thinking of this, Chen Sheng's heart sank slightly.

"Be sure to find out this batch of grain!" Chen Sheng let out a resolute sound in his heart. As a person of later generations, Chen Sheng naturally understood the importance of the South China Sea to the Chinese nation. After pondering carefully, Chen Sheng suddenly had an idea in his heart. He pointed to the map and said, "My lord, have you noticed that the whereabouts of this grain and grass are very similar to the advance of the army?" ”

"Yes, I found out." As soon as Meng Yi finished answering Chen Sheng's question, he discovered the mystery hidden in Chen Sheng's words. If the grain is shipped from Surabaya County, it is most likely to be shipped to Changsha County and Jiujiang County. These two places were the distribution places of the grain and grass of the imperial army. It's just that Meng Yi didn't understand why these people had rushed to buy so much grain from the empire, so why did they transport it to these two places? He asked Chen Sheng puzzled.

Chen Sheng explained: "There may be two reasons: first, these people buy grain to support the local tribes of Baiyue, so that their anti-Qin can be more durable; Second, when our Qin army's military rations are exhausted, we can raise the price, because it is closer to the army and the food supply is timely, and the empire can only accept their price proposals. ”

Meng Yi nodded appreciatively, Chen Sheng's idea was very reasonable, but there was a hint of gloom in his heart, and he said: "If you take such pains to plot something, I'm afraid it won't be a matter of money, and the plan will be big." ”

Chen Sheng smiled bitterly and secretly thought: "The person who dares to blackmail the emperor with this kind of thing is either a genius or a madman. However, Chen Sheng believes that this fireplayer is most likely to self-immolate in the end.

The corners of Meng Yi's mouth suddenly showed a sneer, and it seemed that his thoughts were not much different from Chen Sheng's. However, Chen Sheng also vaguely felt that those who dared to do this might have thought about this consequence and would definitely leave a way back for themselves.

The two of them had their own thoughts, and for a while there was a rare silence in the small hall. However, the sound of cowhide boots scurrying away sounded outside the door, and when he heard the sound, Meng Yi knew that this was Yang Duanhe coming back.

Yang Duanhe's face was purple, and he said excitedly: "My lord, son, there was a fleet anchored in Pei County three days ago, and it has not left yet!" ”
