"Tail the tail? Yue Hailou is slippery. Not only does it mean to excavate the outer moat outside Zhenyang City, but also build an inner city in the city. I don't know how he convinced Chihu people to agree that he was coming towards Chushan so slowly. It was too difficult to pull his tail!"

Tang Qing frowned and looked at the field shrouded in the distance by the moonlight and white frost. He couldn't think of any weaknesses that would be captured by them, forcing him to give up his strategy of entering the camp.

"The answer is there, and we have been prepared for a long time, but we have not had the chance to implement it yet - if you can't imagine it, you will be punished to stand at the city tonight!" Xu Huai said to Tang Qing.

"Water attack?" Tang Qing asked in a low voice.

To the north of the Huai River, to the north of Tongbai Mountain, east of Dafu Mountain (Qingyiling), and northeast of the terrain, the lower terrain, and the Huai River, the upper reaches of the Ru River, and the streams originating from Dafu Mountain (Qingyiling), often rainstorms after summer, causing these areas to be affected by floods all year round.

Zhenyang, the central part of Queshan, and the Pingchuan area in the eastern part are basically Huai River. The Ru River carries a large amount of mud and sand from the upper reaches and has been alluvial after countless years.

Runan, Suiping and other counties have the lowest terrain and the most severe flooding.

Because the rainfall in the upper reaches of the Huai River will be less after summer, the floods in Queshan and Zhenyang are relatively mild, but they are only relatively speaking.

At the beginning of the year, Xu Huai returned to Chushan and summoned everyone to discuss defense strategies. At that time, he had not thought about building a new city on the north bank of Zhouqiao. He mainly considered how to rescue Qingyiling Camp if it was surrounded by enemy groups with absolute advantage in troops.

At that time, I was considering trying to build a dam and intercept the river in the upper reaches of the Wuzhai River.

Wuzhai River, also known as Qingyi River, originates from Qingyi River in the eastern section of Dafu, and is named after it. From Qingyi River to the north, it goes north and goes to Queshan County to turn east and flows into Rushui River.

If a dam can be built near Qingyiling Yingcheng, and if necessary, break the water in different directions, the water can be directed to the near Queshan County and the right bank of Qingyi Mountain, that is, the southeast of Queshan and the northern part of Zhenyang, so as to ensure that the enemy does not dare to rely on the advantage of military strength to siege Qingyiling Yingcheng for a long time.

Of course, this idea is good, but it is never easy to implement.

Due to the limitations of the technology and bonding materials of the state, it is impossible to build a very high interceptor dam. At present, dozens of stone weirs built deep in Tongbai Mountain are as low as possible, or multiple stone weirs are used to store water step by step and raise the water level to irrigate the mountain fields and valleys on both sides of the shore, making the deep steep mountains suitable for living and farming.

Technically, only low dams and low weirs are allowed to be built, and they cannot be washed down or collapsed during the water storage period. They also need to accumulate enough rainwater that can flood dozens of miles deep in a short period of time. So they decided to use low dams upstream. The dam surrounded by the low weirs is large enough, and the project volume is a bit amazing.

At the same time, it is necessary to ensure that the flood direction after the breakage is controlled, so the choice of harbor terrain is extremely careful.

In short, it is an extremely complex and consuming project.

It is also a blessing that Tongbai Mountain has built large-scale cofferdams and stone dams to block water in recent years, and has accumulated experience and talents. There are also Dushui like Yu Chengzhen. The master of construction joined and took two or three months to survey the terrain of Queshan, Zhenyang and other places.

However, in the end, it was given up because the waste was too huge and exceeded Chu Shan's ability to withstand it.

Now Chushan is building a city on the north bank of Zhouqiao. The enemy forces are rushing towards Chushan City with absolute superior forces by entering the camp, intending to cut off the connection between Chushan City and Shimenling and Qingyiling from the outside.

However, the enemy's camps are mainly distributed on both sides of the Mingxi River.

By the same token, as long as Chushan can build dams and block water in the upper reaches of Mingxi River, the accumulated rainwater in the upper reaches will not go through the Mingxi River channel and enter the Huai River, but will diversion to both sides of the Mingxi River to flood the land.

The banks of the Mingxi River are quite flat, and it is difficult to directly destroy the camp, but submerge the fields and jungles around the camp, turning them into a water lake, which cuts off the connection between them and with Zhenyang City and Queshan City behind them.

This will turn the camps into isolated islands trapped in the water, making it difficult for the enemy cavalry to gallop across it, making it difficult for their food and fodder to transport. At that time, Yue Hailou will not retreat.

What can he do if he doesn't retreat? Seeing the camps being attacked by Chushan's elite troops, can he have no way to reinforce?

Of course, although the terrain on both sides of the Mingxi River has been surveyed and there is no technical problem, Yuehailou is also blind.

How could Yue Hailou not understand the intentions here?

Therefore, if Yue Hailou does not want to sit and watch Chushan build a dam in the upper reaches of Mingxi River and at the same time, he must give in to the Chihu people, and it is impossible to retreat easily without success, so he must send troops to attack the upper reaches of Mingxi River or attack Chushan City.

This also achieved the intention of holding his tail and taking it out and hitting it.

"Even if you can force the enemy out of the camp to fight in the field, it will be absolutely not easy!" Xu Wuqi signaled the personal soldiers on both sides to retreat and sighed in a low voice.

Everyone looked grim. They said that they were not afraid of any strong army in infantry battles, not to mention that the puppet Chu army under Yue Hailou is not yet at the level of a strong army, but it is undeniable that the forces between the two sides are very different.

In addition to the three key points of Cairo Mountain, Jiuli Pass and Qingyi Ridge, some forts and camps built in dangerous passes also need to be stationed to prevent small groups of soldiers from penetrated and penetrated into the depths of Tongbai Mountain. They can truly gather forces to the eastern foot of Chushan City and Shimen Ridge on the south side, including the Tianxiong Army and the state soldiers, with only 13,400 troops.

Yuehailou can currently mobilize more than 30,000 troops on both sides of the Mingxi River, and nearly 5,000 elite cavalrymen of Chihu are watching.

The Chihu cavalry, led by Molihu, came specifically to watch the Chu Mountain, and even blatantly practiced infantry and cavalry combat with Zhong Changqing's infantry on the left bank of the Mingxi River.

"The time is not yet ripe enough. The pseudo-Chu camp has not yet been promoted to the west bank of Mingxi River on a large scale, so they may not be able to bite the hook, and we will also need a month to make more careful preparations," Xu Huai looked at Tang Qing, Han Qi, and Yin Peng and asked, "Who are you taking on this task?"

The terrain of the upper reaches of Mingxi River is narrow and is about to lead the main force of the enemy to attack. Only one elite force needs to be filled in, and then add troops to it according to the casualties.

At present, the production of fine iron in Chushan has increased significantly, but the construction of some combat equipment and excellent armor is still time-consuming and labor-intensive. In the next month, we can only focus on strengthening one, rather than engaging in egalitarianism.

"Since I guessed this strategy first, of course I will go to guard Huangyang Village!" Tang Qing said first.

Huangyangzhai is located on the right bank of the upper reaches of Mingxi River. It was originally a patrol army camp under the Qingyiling Metropolitan Inspection Department. The original purpose was to support each other with Shimenling Village and guard the gap between Mingxi River Valley and Qingyiling and Shimenling, in order to prevent small groups of enemies from penetrateing into the valley between the North Ridge of Tongbai Mountain and Dafu Mountain.

The key point of this battle is to advance an elite group of soldiers and thousands of dam-building workers to Huangyangzhai to attract the enemy to Huangyangzhai to fight before.

We definitely can't just defend Huangyangzhai.

Otherwise, the enemy would also build camps near Huangyangzhai, and thousands of labor and supplies would have no way to go out to Huangyangzhai to build a water-blocking dam, so there would be no threat at all.

However, Huangyangzhai is located on the south side of the low-gang belt extending eastward between Shimenling and Qingyiling. It is called Tiemu Mountain and is also the dividing ridge between Qingyishui and Mingxi River. It is more than ten feet high and thirty or forty feet high. It extends more than ten miles in the southeast of Qingyiling to the junction of Queshan and Zhenyang counties, which is conducive to defense and not conducive to offense.

"We have thought about it for a long time, it just depends on whether you can guess it!" Yin Peng and Han Qi said.

"No need to fight, Tang Qing is responsible for guarding Huangyangzhai," said Xu Huai. "Once Yue Hailou is forced to use troops to Huangyangzhai, if you want to gain a foothold in the upper reaches of Mingxi River, you will inevitably launch an offensive on this side at the same time! The defense here will not be easy!"

Now that Chushan has just built an outer city wall, the defense is still very simple - if you act too hasty, Yue Hailou may not attack Huangyangzhai forcibly. It is very likely that while a group of elite Chushan forces are concentrating their forces to attack and defend the simple Chushan City.

Therefore, in the next month, we must further improve the defense of Chushan City.

The next morning, Tang Qingxian led hundreds of elite troops from the inside to Huangyangzhai to garrison; Yu Chengzhen also took more than a dozen disciples to Huangyangzhai to make more accurate calculations on building dams and blocking lakes in the upper reaches of the Mingxi River.

Chushan City takes the outer line east of Shimenling, and it is about 40 miles to Huangyangzhai. It can be reached in half a day. However, when you go to the inner line, you must first cross the river to Zhouqiao, then take Tongbai Mountain Road to Huaiyuan, cross the river to enter the northern slope of Tongbai Mountain, and move east from the Xinfagu Road between Beiling and Dafu Mountain to reach Huangyangzhai.

The inside line has to walk 250 miles, and many of the newly built mountain roads are still very narrow, and it is difficult to broaden further in a short period of time, and the marching speed cannot be fast.

This is also a key reason why the outside line east of Shimenling will not easily be asked to approach the enemy's strategy of building a company camp by advancing and cutting off the enemy.

At the same time, Chushan City further built an internal and external horse-resisting wall, excavated an internal moat, built dozens of military yards, and created stone-tower equipment.
