The Black Flag Army rushed to the Qin Emperor's Courtyard and retreated, and quickly evacuated to the east, although it is said that the troops in this area of the Qin State are empty now, but after all, it is a lone army deep into the hinterland of the Qin State, once it is entangled, it will be dangerous, they only brought less than ten days of war horse forage and dry food, and the weapons and equipment are almost consumed in this battle.

"Your Majesty, how about we take the opportunity to poke Wu Yuehou's ass?"

Zuo Xuan was very excited, he put forward a suggestion like Zhang Xian to sneak attack Wu Yuehou, this suggestion was also quite tempting, Zhang Xian was also a little moved, and all the soldiers were eager to try.

But Zhang Xian finally calmed down.

"According to the plan, withdraw first to replenish the substance, if you don't feel like it, sweep those places around Wuchang County, and then hand over Cangyue Mang, which can be regarded as a favor. ”

Although Zuo Xuan was a little unwilling, he thought that it was a bit too risky to attack Wu Yuehou, although it was said that they could rush to the back of Wu Yuehou's army in less than five days, but they also became tired at that time.

Besides, the Black Flag Army's attack on the Qin Emperor's Courtyard will soon be known by Wu Yuehou, and if the Qin family reacts quickly, it will be necessary to send a large group of cavalry to search for the Black Flag Army.

There is no shortage of war horses in the Qin State, and there are hundreds of thousands of cavalry, although the combat power is not as good as the Black Flag Army, but it can fight locally, the logistics support is sufficient, and with the participation of local troops, once the Black Flag Army is entangled, it will be difficult to get out.

There is no need to take this risk, even if it succeeds, it doesn't make much sense, after all, Wuyue Hou has gathered nearly two million troops there, and the entire Shangcheng country is full of Qin military camps.

Wu Yuehou did not cross the river, he was actually waiting for the arrival of the Qin Emperor, and there were many war supplies that had not yet arrived.

The Black Flag Army rushed back to Wuchang County three days later, and also swept a half-county in the northeast of Qin State, sweeping away the local troops and official offices there.

Although Cangyue Mang has the intention to occupy these land cards, but some places are really difficult to hold, so he chose the eastern part of Dongze County Kajiao Mountain District as the boundary, the eastern half of the county plus the half of the county of Wuchang is in the bag, the terrain of the Kaqiao Mountain area is prominent, but the garrison guards the pass to resist the Qin army, it is impossible to block hundreds of thousands of elite troops of the Qin State, but it is no problem to block hundreds of thousands of ordinary Qin troops, there are mountains and rivers in Wuchang County, and they can also refuse.

Cang Yuemang is indeed not greedy, which also makes Zhang Xian admire it very much.

If Cang Yue blindly expands outward, it will provoke the Qin army to rush in, and there will be a danger of destroying the country.

Now Qin's mind is not here, Cangyue Mang's small fight occupies two and a half counties of Qin, and they are all large grain-producing counties, as long as they can be defended, it will take less than two years, and the dilemma of grain loss will be solved.

The geographical location of Cangyue Country is not good, it is not a grain production area, it is good to be able to maintain the annual supply of people without loss, if there is a disaster year, the food gap is large, and it needs to be purchased from outside, most of the previous Rakshasa Sect purchased from Qin in their name to supply Cangyue Country.

Therefore, Cang Yuemang coveted the Qin State next to their several large grain-producing counties, which accounted for one and a half in the early stage, and now they have another one, and they are content.

The Black Flag Army didn't stay long in Wuchang County, rested for a while, and then returned to the Maoshan base, after all, there are still many wounded who need to be treated and recuperated, brothers who died in battle need to be buried and compensated, and many things need to be dealt with after a big battle.

Zhang Xian didn't go to see Cangyue Mang again, and followed the Black Flag Army to the Maoshan base first, and then took Bai Ling'er back to Shunyi City.

He cleaned up the Qin Emperor, he must have scared the Qin Emperor a lot, but he would not be naïve to think that the Qin State would withdraw his troops, but the delay in the attack is certain, the Qin Emperor was frightened and needed to calm down for a few days, and the imperial expedition must be canceled, and when he recovers, he still needs to re-coordinate with the Taiwei Mansion, the Ministry of War and other departments to reformulate the plan for the use of troops, and when the discussion is over, the battle plan will be approved and then sent to the front line, this time will not be short.

But in this way, Jiang Peng's lonely people all the way to the bitter end.

Zhang Xian didn't plan to eat Jiang Peng, how could he not die in a war, and Zhang Xian couldn't stand the big losses, so he could be trapped and let it rout on his own, but there were also strategies to deal with these Qin troops, if it was found that Wu Yuehou had signs of a large-scale offensive operation, Zhang Xian would destroy Jiang Peng's men as soon as possible, otherwise he would be involved and have to draw troops to deal with them.

Now that the stalemate is beneficial to Xia Guo, the first thing Zhang Xian said when he returned to Shunyi City was that it would be good to have a heavy snowfall.

Maybe the sky should be in response to Xia Guo, and sure enough, two days later, there was a heavy snowfall, and the snow was knee-deep for a day and a night, and Zhang Xian was so happy that he almost didn't run around Shunyi City.

"Haha...... God help me!"

Although this heavy snow restricted the use of troops on both sides, it was a disaster for the Qin army and a help for the Xia army.

"Convene Wang Yan, Liu Yong and others to discuss the matter. ”

Zhang Xian instructed Xiao Fei.

This time, Zhang Xian did not go to the staff headquarters, but in his own courtyard.

It took half a day for Zhang Xian and others to formulate a battle plan to eliminate Jiang Peng's men, and they did not hesitate to mobilize more than 500,000 people from five corps.

In early October, a snowflake campaign was launched.

There was not much suspense, Jiang Peng's soldiers and horses who lacked food and clothing were wiped out.

The Xia army suffered more than 100,000 casualties, the Qin army died more than 100,000, and there were more people who surrendered.

"Damn, it's a bit of a loss to lose a corps member in this battle!"

Zhang Xian was a little depressed, he didn't expect Jiang Peng to be so powerful in commanding the army, and he deserved to be a famous general in the northwest of Qin.

After the war, statistics showed that the Xia army suffered more than 60,000 casualties, more than 30,000 were seriously wounded and disabled, and there were not many minor injuries, indicating that the battle was fought very hard and suffered huge losses.

Almost the loss of combat power of a corps.

In addition to heartache, the generals of the unified army began to sum up the lessons and lessons, and they really underestimated the Qin army before, and they were a little arrogant, and they needed to rectify the thinking of generals at all levels.

Although the two newly built corps suffered heavy losses in this battle, it was the first time that other veteran corps had such big losses, which dealt a great blow to them and sounded the alarm.

"Withdraw the newly built corps to the south of the Yangtze River for rest, replenish the source of troops and intensify training, and the remaining corps shrink the defensive line and gather around Poyang Lake, the current situation is unfavorable to us, and we can't meet the possible all-out attack on Wuyue Hou head-on, so we can't hold on, so we retreat to Jiangnan or Poyang Lake, and slowly encroach on the Qin army by guerrilla methods. ”

After the battle, Zhang Xian summed up for a few days, and finally Zhang Xian made a decision, with the current situation, it is impossible to fight hard with the Qin army, they can't afford to lose, it has entered winter, and it has snowed for several days in a row, the Qin family may not dare to cross the Chen River to attack, but they have to defend themselves, so Zhang Xian made the decision to shrink the defense line.

There are not many residents in the area north of the Lijiang River in Wuwei Prefecture, and the Xia army does not have to send troops to garrison every town, shrinking to the periphery of Poyang Lake, which can be attacked and retreated, but it is really impossible to enter the Lijiang River from Poyang Lake and retreat to the south of the Yangtze River.

"Then what about the arrangement of the two corps and the Black Flag Army in the Suri Kingdom?"

Wang Yan threw out this question.

The crowd fell into a brief silence, because once the army retreated to Jiangnan, the three corps were basically cut off from retreat, and the material supplies could not be delivered.

Zhang Xian and the others thought about it and thought about countermeasures, but after a long time, it was Wang Yan who spoke first:

"Your Majesty, in the opinion of the ministers, we can't completely abandon the northern part of Wuwei Prefecture, we must hold the east line of Poyang Lake, and we can't cut off the connection channel between Yanjiang City and Liangyi City, after all, now the naval army is restricted because of the season and the display of the army of Qin and the north bank of the Chen River, and it can't be free to sail for the time being, and the waterway is basically broken, and the land route is broken again, not only is the Suli country dangerous, but the points we laid down are also destroyed, and it is really reluctant. ”

Wang Yan means that he can temporarily abandon the territory west of Poyang Lake and Kanding City, but the passage of the west wing of Beishan cannot be abandoned, although it is very difficult to hold this place, after all, there is no danger to defend, but it is not impossible to defend, there is no dangerous place, you can build a dangerous place.

Zhang Xian and Liu Yong waited to see that Wang Yan didn't seem to finish speaking, so they didn't say anything and looked at him, waiting for him to follow.

"We can dig the ice on the lake and pour water to build an ice wall to keep the enemy ......"

"Good!"

Before Wang Yan finished speaking, Zhang Xian understood what he meant, and applauded.

"While the Qin army hasn't moved yet, let's act immediately. ”

"Yes!"

In the middle of October of the seventh year of Xia Guohongyuan, Xia Guo chiseled the lake surface on Poyang Lake about one mile wide, more than 30 miles long, took ice and snow to water and cast an ice wall more than 20 miles long, it took less than ten days, and Xia Guo just completed this feat, the whole army of Qin started to cross the Chen River, but Chen Jiangnan Li River north Poyang Lake West, there is no figure in the range of thousands of miles, Xia Guojian wall Qingye did too thoroughly, Wu Yuehou army came to a deserted place, can not cross the Li River, the west is dead, and the Shenwei army over there occupies a favorable terrain to refuse, with the cooperation of the Zongye State and the Bashu Kingdom Apocalypse Army, even if the Qin army has great ability, it is also a sighTo the east, he found that there was an impassable Ming River in Poyang Lake, and an ice wall inexplicably appeared on the land road, and this ice wall was seen widening and tallening every day, and the ice wall was set up with a secret hemp chariot and a unique god-killing crossbow of the Xia Kingdom, which made the Qin army discouraged and did not dare to step forward.

At this time, Wu Yue Hou and the others suddenly fell into an embarrassing situation.

There is no way to advance or retreat.

Enter, originally Poyang Lake froze and could walk, but now it has been chiseled so wide by the Ming River, and looking at the various remote appliances on the opposite side from afar, if you want to rush over, it is basically impossible, Li Jiang does not have to worry about crossing the past, Li Jiang In addition to the thawing of the river, the river is still so choppy, not to mention that there is a strong Xia State water army cruising there, and the butcher appears from time to time, and the Qin army does not dare to try even if there is a ferry.

With an army of more than 2 million, it is really embarrassing to stay in this barren land, but it is really embarrassing to retreat without the permission of Emperor Qin......
