Jiaxian Mopi, where Zhao Yanjuntun is located.

Mopi and Shaobi are both water conservancy projects, which build reservoirs and dams to block water and store water for irrigation downstream.

Zhao Yan served as Xu Huang's protector as an official of the Wei Kingdom, and now commands 20,000 soldiers from the Mopo army; Xu Huang was in the military camp on both sides of the Lishui River, with nearly 10,000 troops.

The Lu Jian Department under its jurisdiction is stationed in Duyang, and the Xu Shang Department is stationed on the east bank of the Lishui River, echoing with Lu Jian, and Xu Huang is fifty miles behind Xu Shang, which is considered a three-layer defense.

On the 24th, Tian Xin went north along the blocked water, began to camp on the west bank of the blocked water, and personally led more than ten horsemen to cross the river to observe the city of Duyang.

The south of the mountain and the north of the water are yang, the city of Duyang is called Duyang, but it is close to the west bank of Lishui, so the Tianxin military camp and Duyang are separated by only fifteen miles of road, the middle terrain is gentle, and there is only less than two zhang wide water blocking in a dry period.

The wolf smoke was billowing up in Duyang City, and Lu Jian could only see the smoke from the fire set up on the riverside on the west bank of the blocked water, and the scouts kept reporting back, all of which were bad news.

"General, the enemy village was first established, and there were four battle flags on the riverside, which were the Pavilion Marquis of Hugu, the deputy general of the Left Army, the General Huya, and the left vanguard of the Northern Expedition."

The main book came to report, and he also handed in the bamboo slips written by the scout, which made Lu Jian hesitate: "The enemy general Tian Xin is brave and fierce, if he is the vanguard, there will be a large army coming one after another." The city of Duyang is small, why don't you withdraw your troops tonight to avoid sharp edges? ”

Jun Sima replied cautiously: "Without the order of the right general, our army will retreat before the battle, and I am afraid it will be difficult to be good." ”

Lu Jian looked around at the surrounding military officials, all of them had earthy faces, and his heart was even more sad.

The battle of Hanzhong was broken by the general Zhengxi, and when he fought Hanzhong again, Cao Cao himself almost had to confess in Hanzhong.

The Jingzhou battlefield made the Wei generals even more frightened, and more than 20,000 people of Guan Yu counterattacked Cao Ren, who was about to march south, and won successive battles, and Cao Ren had no power to fight back.

Then the Han River swelled, drowning the Forbidden Seventh Army, which reminded people of the meteorite that fell from the sky of Emperor Guangwu.

Later, it was even more terrifying, Jiangdong betrayed the alliance Sun Quan to raise 100,000 troops to attack Jiangling, and the first war lost the governor Lü Meng, and the second war Maicheng almost completely damaged the Chinese army. Then came the great epidemic, and Sun Quan sued for peace in Jingzhou.

Previously, Nanyang County Shoutian Yu and the rebellious general Wen Ping joined forces to raise Nanyang to surrender Guan Yu...... Lu Jian watched all this happen from the sidelines, how could he be indifferent?

Thoughts such as fear of war, no way to advance or retreat, and no choice but to surrender swirled in his mind, and then looked at the military officials around him who did not belong to him, Lu Jian could only smile bitterly and wait for Xu Huang's order.

Tian Xin removed the superfluous decorations, wore an iron basin collar armor and rode a yellow horse, the Li horse Mondo with a saddle, a set of tailor-made and sewn patent leather vests, and was moved due to irritability, and followed Tian Xin.

Nineteen horsemen stationed two miles outside the city of Duyang, and saw that the distance between Duyang and Lishui was only one mile.

"It is worthy of the throat of the north gate of Nanyang."

Naturally, it can be seen that the different meanings of the plugging sun to the north and the south are held, the Central Plains holds the blocking, and the rear materials can be safely transported from Lishui to the blocking, even if the battle is defeated, the defenders of the blockade can quickly retreat to the east bank of the Lishui.

For Nanyang, holding the blocking sun will harass the other party's water transport route, and just the upstream interception of water can make the downstream very uncomfortable. There is also a water as a barrier to the east, which is conducive to defense.

Duyang is the throat passage between the Nanyang Basin and the Central Plains, with Yaoshan Mountain in the north and Tongbai Mountain in the southeast...... Good for defense, but also for decisive battles.

Between Yexian and Mopi, there is a holy place called Kunyang, the legendary place where meteorites fall from the sky.

It is now clear why Cao Ren gathered his army to attack Jingzhou in July last year, when the scorching heat in June was not suitable for the expedition, and in July, when the temperature became cooler, the rain would increase.

The key is to increase the rainfall, which can ensure that the flow of water and water blocking increases, and can barely pass through heavy boats.

It was also based on the understanding of the rainfall and water system in Jingzhou, as well as the military situation that should be reported in the Central Plains, that Guan Yu was able to pinch the right time and hit Cao Ren's throat with an extremely accurate punch, so that Cao Ren could not exert three percent of his strength, so he rolled on the ground holding his throat.

is also because of the lack of water blocking and Lishui, so after the Battle of Chibi, Cao Cao would rather go to Guanzhong and Sun Quan than come to Jingzhou to find trouble with Liu Bei and Guan Yu.

There are the Yellow River and Weishui to transport military rations, and it is even simpler to fight Sun Quan, and there are waterways to transport military rations.

Now the population is sparse, and the food is transported by manpower...... Low efficacy can also affect production, and the gains outweigh the losses.

If you can't win a battle, you will lose money.

A lot of half-understood fragmentary knowledge in the past is now condensed, giving Tian Xin a deeper view of the Central Plains battlefield.

The Jingzhou army fought smoothly, and the naval army made great contributions.

The Jiangdong Army defended sharply, and the naval army made great contributions.

It is the water army that has contributed to it, and it is this high-efficiency and low-cost mode of transportation.

Compete for control of the water system now, control of the railway in the future, and air supremacy in the future.

Seeing this, Tian Xin showed a cruel smile: "Brother Meng Xing, if our army can break through the armies of Lu Jian, Xu Shang, and Xu Huang and be able to enter Kunyang, what should the Wei army do?" ”

Zhang Bao was stunned, recalling the relevant water system, geographical knowledge, and Zhang Fei's earnest teachings: "Kunyang is a small city, control and choke water, and live in the upper reaches of Rushui. If I occupy it, the Central Plains will oscillate, and I will be attacked by the Wei army. ”

Ye County controls the Li River, and the flow of the Li River is not as good as the water of the water, and it flows into the Ru River from Yun County.

In the northwest of Kunyang, there are Luyang, Yangren, and Liang County, which is where Sun Jian's main march route is located when the heroes fight against Dong.

Tian Xin reluctantly withdrew his gaze from the reluctance of blocking Yang: "When Nanyang rests and accumulates two-year-old food, I will march into the Central Plains." Now, first pull out the plug sun, so that Xu Gong knows that I am powerful. ”

The defenders in the city of Duyang saw Tian Xin's nineteen horsemen leave, and Lu Jian sent flying horses, some to report the military situation to Xu Huang, some to the protector Zhao Yan, and some to Xu Du Cao Ren.

Back to the camp on the bank of the blocked river, it was not dark at this time, and there were still ships transporting equipment to the camp.

The low and shallow boats in the blocked water could not carry people, and now they are empty ships loaded with equipment, and there are horses on both sides of the river.

In the downstream Liyang City, Ma Chao and Guan Ping each sent cavalry troops to arrive almost at the same time, totaling more than 2,000 horsemen.

Counting the 800 cavalry in Zhang Bao's hands and the more than 100 cavalry of the Huya Army, a huge cavalry army with a scale of 3,000 cavalry will be formed, which is a strategic force in terms of the current scale of the Central Plains battlefield.

That night, the Liyang military intelligence arrived at the water-blocking camp.

Tian Xin is studying by the bonfire, and there are many bonfires set up outside the barracks, and there are sergeants who are good at raising dogs to lead the hunting dogs with the army, and they are on duty together at this moment.

In addition to the barking of dogs and the neighing of horses, there are only the occasional sound of partridges or the sound of horses' hooves in a fixed direction.

"Junhou, General Zuo allowed to borrow troops, and sent Yamen General Ma Dai to lead 1,500 horsemen to Liyang to stand by, and arrived to rest before nightfall. The cavalry battalion sent by General Long Xiang arrived at noon. ”

Yu Zhong suppressed his excitement, this was his first battle.

Tian Xin took out the military order that had already been written and handed it to Yu Zhong: "Send it to Liyang immediately." ”

Only by expanding the scale of the war in Nanyang can the resistance of the main force to the east be alleviated.

Chibi, Wulin, Lukou, and Hanjin are all in hand, and the Jiangdong Army has to defend Jiangxia on the north bank and Wuchang on the south bank.

The only thing to worry about was the reinforcements of the Wei army, and Cao Xiu could quickly reach the northern part of Jiangxia to participate in the battle by going to the Dabie Mountains; Zhang Liao can go to the front line of Anhui City to help.

In the event of an emergency, the Jiangdong Navy would assist in transporting the Wei army.

It may be that in this Eastern Crusade, the number of troops gathered around the battlefield to participate in the battle can exceed 200,000, and the follow-up grain transportation soldiers, auxiliary soldiers, and civilian warriors will be about 300,000.

Now that the military food reserves of the Wei army in the Central Plains are depleted, the more they are attracted, the greater the logistical burden of the Cao army.

It is only this year that can bully the Wei army's lack of military food reserves, and there is only one such fighter.

He was ready to fight, and Xu Huang also wanted to hit the Huya Army hard to boost the morale of the Wei army.

At night, Xu Huang's military order was also conveyed to the front line, and Lu Jian divided two battalions of soldiers into two battalions to go north along the Lishui River, and walked around the foot of the mountain to block the upstream of the water; Xu Shang gathered all his troops and horses, crossed the Lishui River to the south, marched on the south bank of the Lishui, and hid in the reeds around the Wanghua Pavilion at dawn.

Both sides are waiting for dawn, waiting for the movement of flank forces.
