Lishui is clear and the mountains are steep. Unlike Jiangnan, the mountains and rivers of Huainan give Xiong Jing a taste of being out of the world. If he could build a palace in such a place in the future and rowing and playing in the water, wouldn’t it be fun? Unfortunately, this era was not the era of traveling around and experiencing the goddess, and there were Feixun stations in Xiangshui and Ganshui. When he was in Panyu, Zhao State asked for help almost every day. In Zhao State, the State of Chu State would not be too far away, otherwise why would he have to work hard to meet with the tribes of Baiyue? Why should he personally inspect Yuechengling, one of the five ridges defense lines?

The battle was full of passion, but preparations were so boring. And no one knew whether the defense line of Vietnam, the Wuling Line, which was built with huge funds, could really play a role.

History has proved that the Five Ridges are not worth defending. Qin attacked Lingnan to build Ling Canal to transport grain, and the troops were divided into four routes; the Han Dynasty sent troops to Lingnan, but they walked the Guiyang Road (via Linwu). Although the Five Ridges were steep, the ridges and ridges were not like connected. There were many paths in the middle. The soldiers who penetrated the paths bypassed the pass, and over time, they could always achieve results.

This reminded Xiong Jing of the old Ying again. The security of the provinces south of the Yangtze River was all based on the Jianghan Plain. The Chu State had lost the old Ying, and the only thing that was fortunate was that Xiayi (Wuchang) was still in its own hands. The priority of building a city in Xiayi was higher than that of the towns in the country, second only to Daliang, where the city has begun to be built.

Although Huai Shang is fertile, it is not a real strategic location. Once Daliang is lost, the battlefield between Jianghuai is the battleground. As long as Xiayi and Huainan defend it, the southeast can be stable. The so-called "Wuchang will survive in the southeast, and those who lose in the southeast will die." However, offense is the best defense. If the old Ying can be recovered and the two cities of Xiangfan can be built at the intersection of Bai, Tang and Han rivers, then everything will be perfect.

In Xiang Yan's view, doing so would inevitably lose Zhao State. The combat plan formulated by the Operations Department was very deceitful. The timing of sending troops was chosen to be when Zhao State could not support it. Handan was about to break the city, and the weak division and fake division cooperated with the Wei army to pretend to move towards the Yellow River area, making a rescue situation to motivate the Zhao people to fight and attract the Qin army to draw the final reserve team.

Then - Xiong Jing guessed that the most perfect attack time in the Battle Department's heart was the moment when the outer city of Handan was captured by the Qin army, and then 200,000 elite Chu troops rushed into the old Ying and destroyed everything where Qin was.

The plan was very exquisite, but Zhao State was destroyed. Xiang Yan strongly opposed this. He believed that the value of the old Ying was far less than that of Zhao State. Chu and Zhao State, one in the south and one in the north, were the best defense at the moment. Since we wanted to restrain, we had to save Zhao; since we saved Zhao, we could not surround Wei like Sun Bin. Surround Wei could not save Zhao. Although the Wei army was ambushed, the Wei army retreated after attacking Handan.

When they reached the source of Lishui, Xiong Jing, accompanied by the chief of Xiou Jiejun, rode a horse and walked through Yuechengling Mountains. If it weren't for Yueren and Chu's clans, it would be difficult for outsiders to find this passage to cross the Five Ridges. Even if someone had given advice, Xiong Jing would not know where Yuechengling Mountains were before standing at the top of the mountain.

After climbing several mountains in a row, leaning against the high-power Lu Lijing, Xiong Jing saw the Xiangshui tributary (Haiyang River) heading north on the right, and the Lishui upstream (Shianshui) heading south on the left. The closest line of the two waters is about twenty kilometers apart. This section of the ridge is much lower than the front and back ridges. It is about three hundred meters wide and twenty meters high, and the soil is the Yuechengling Ridge.

"Can a canal be dug here?" Feng Renjiu was very young, and he was Feng Renjiu's son, named Qiao. If he had not tied his hair, he would have almost become a Yue person.

"It's easy to report to the king." Feng Renjiao bowed.

"Very easy?" Xiong Jing looked at him, wondering if he was pretending to be amazing or if it was indeed the case.

"Yes." The young man pointed to the low forest. "There must be water when digging a canal. Without water, it is useless to make it happen. From my opinion, Li water is not enough to lead, so it can only lead Xiang water into the canal. This water, but this water is lower than Li water..."

"It's low?" The forest was dense, and Xiong Jing could not tell the high or low at all.

"Yes." A simple leveling device was presented and then moved back by Xiong Jing. This was the instrument he invented. "The nearest two waters, the Hunan water is lower than the Li water, and if you want to divert the Hunan water into the canal, you need to build a seven-meter dam, which is one; but if you can build a dam further away, the Hunan water is only a little five meters lower than the Li water, and you only need to build a dam of one foot. However, the ditches are longer than the previous one."

"How long?" Xiong Jing asked, as if he could understand the two positions he was talking about.

"It's only ninety miles." Xiao Fengren clarified. "Just dig 90,000 square meters of mud and build a stone dam of more than 20,000 square meters."

"Only digging 90,000 square meters of mud?" Xiong Jing was surprised that the project volume was so small. It took fifteen working days to build a city, but no digging dredging. Even if digging a square of mud takes ten working days, 90,000 square meters of mud is built, and 10,000 people will be completed in three months. More than 20,000 square stone dams are even simpler. "If there are ten thousand people, wouldn't it be done in half a year?"

"It's only half a year." Feng Renjiao said. "The Qin people did not have cement glutinous tendons, and I think they were elected."

"Is there any good solution?" Xiong Jing asked. He heard that Lingqu could be achieved for half a year, and he immediately frowned.

"Yes." Feng Renjiao's eyebrows and eyes were very similar to Feng Renjiu, and his words were also like that. "Please look at the ridges in front and behind the mountains are high, and the low part is Yuecheng Ridge. This section is only low, I have measured it, and the low part is only nineteen miles. If you can build a city here, you can break this canal."

The Lingqu is east-west, from east to west, and Yuecheng Ridge is north-south. If a city is built at a low point of a ridge about nineteen miles long, the Lingqu will have nowhere to be dug.

"Good!" Xiong Jing finally smiled a little. This was what he wanted to hear the most. "How about the rest of the ways?"

"The other roads will also build cities and equipment." Fengrenjiao Road. Building cities is the most common and effective way to defend.

"How long are you?" Xiong Jing asked. According to the standards set by the building of the mansion, it takes 90 hardware to build a city wall. Although concrete is not necessary for the mountain and stone can be used, it should also be costly, especially the mountains are inconvenient and the weather is stuffy.

"I am..." Feng Renjiao hesitated for a moment, and saw Xiong Jing looking at him, so he had to say, "I am more than two hundred miles away."

"More than two hundred miles?" Xiong Jing was shocked. This was beyond his imagination. He thought the Lingqu was long, but he didn't expect that the Lingqu was so short.

"However, Linwu is the longest, and it needs to build three sections of the city wall, which is more than 110 miles long; Dupangling is second, and two sections of the city wall, which is more than 80 miles long; the rest are not long, eighteen miles long, or more than ten miles, totaling two hundred and fifty miles."
