At this time, the Qi State already had copper cannons, the quantity was not large, the quality was not good, and the geometric level was not very sufficient, but in order to prevent the copper cannons of the Qi State, the garrison outside the main city could not be configured without considering the opponent's artillery as before.

The garrison has no masonry structure at all, and the location is very high, so it will not be flooded, and the biggest disadvantage of rammed earth and water resistance is also eliminated.

The other side has cannons, whether good or bad, considering that the city wall is actually outdated, and the masonry city wall is also easily smashed by iron cannonballs to form fragments, killing and injuring the defenders.

The thick soil slope can absorb enough energy and is not easy to be blown down, but the disadvantage is that it is easy to be attacked by ants. However, under the premise that the defender's firepower is sufficient, this disadvantage is not a disadvantage.

Inside the city, several sappers were watching a group of people, using pulleys and other tools to prop up a huge cloth bag painted with wood paint, and a hanging basket was placed underneath, which was also filled with a special torch made of tung oil and pine resin, which was used to lift into the air with a clairvoyant mirror to observe the enemy's deployment, and command some heavy copper cannons to cross the garrison for indirect support if possible.

Except for a part of the artillery concentrated, the rest were deployed on specific batteries according to the plan of the sappers.

All this, or the city defense technique from the Mozi era twenty years ago, has been ahead of the times.

It is nothing more than the use of gunpowder mines instead of gunpowder, light copper cannons instead of transfer machines, heavy bronze cannons instead of domestic cars, hot air balloons instead of observation towers, and simple arquebuses instead of crossbows.

However, the concept of the overall defense concept, the cross-fire of the wall, the mutual support of the Weaver Girl's triangle, the repayment of borrowed people's food and houses after writing contracts, the choice of decisive battles in the field as much as possible, and the deployment of in-depth defense in echelons to defend the city, have not changed.

The Mo family's city-defending skills are unparalleled in the world, not relying on those few mechanical skills, but relying on a defense system that is far beyond the rational deduction of the times.

With only one or two magical machines, the Mo family could not be able to crisscross for a long time before the appearance of the Mo family, and even reconcile the wars of Qilu, Chu and Song.

It seems bizarre, but in fact, the essence has not changed, and it is in the same vein.

The only difference is that Shi Shi is not prepared for a decisive battle under the city, nor does he regard this defense of the city as a defensive defense, but only a strategic support point when the time has finally arrived to encircle and annihilate the Linzi army.

The second division was dispatched to organize the defense of Yingyi, and he was sure that with the current siege methods of the Qi army, he would not be able to take Yingyi, which was now armed to the teeth.

Logistics is not in consideration, because if the city is besieged, the logistics of the Qi State will collapse first, and the Mo family occupies Liang's father, and can always threaten the back of the Qi army, so it is impossible for Yingyi to be breached.

Based on this consideration, the Gongzaoye on the southern front received a suitable letter discussing the upcoming war, which was quite coincidental.

Gongzaoye's background is a scholar, not a nobleman at the level of a doctor, so he doesn't understand what Tian Wu's sudden action is about.

But no matter what Tian Wu was going to do, he and Shi considered the same way to deal with it.

Meng Sheng also finished reading Shi's letter on the side, and said with a smile: "This is a coincidence, presumably our letter also happened to be received." ”

"Our ideas are the same, no matter what Tian Wu does, in addition to attacking and cooperating with him in the south, we must also keep an eye on the direction of Yishui and Qufu."

Gong Zaoye nodded and said: "We don't have to think about what Tian Wu wants to do, because no matter what he does, the mountains and rivers will not change, and there are not many choices he can do." You see......"

The rough fingers pointed to the map on the table and said: "Father Liang is in the hands of our army, which causes Lu Guo to have little room for Tian Wu to move. ”

"If he wins the Yi is fake, and enters Qufu to support the coup of Lu Gongzi in order to seek the Luqi alliance, Liang's father's army can directly penetrate Qufu, as long as we can hold out until Liang's father's army comes, Tian Wu will be defeated."

"If he really wins the Yi and makes a desperate bet, then the victory is an anvil and the direction of Liang's father is a hammer, and he will still be defeated."

"The matter has come to this point, what we need to consider is to completely annihilate the Linzi Legion, and the direction to pay attention to in this pocket is Yishui."

"You also know why Tian Wu and Tian Qing didn't withdraw directly in the direction of Yishui before. But at that time it was certain that they would not go from there, and it would not be the same as where they would flee from after their defeat. ”

Meng Sheng still understands this truth.

Yingyi was stuck, Wei Han chose to stay on patrol, and Lu Guo's attitude was ambiguous, after these three conditions were met, it seemed that there was still a trace of life in the direction of Yishui, but it was actually a dead end.

Tens of thousands of troops, slow to move.

And the Mo family has shown far more mobility than Qi from the Battle of Lushui to the Qi-Mo War this time, especially after seizing Yingyi and Liang's father, even if Tian Qing and Tian Wu are stupid, they know that they can't fight the Mo family with mobility.

The retreat is not a rout, if you want to ensure the withdrawal of tens of thousands of troops, you need someone to defend a few cities to buy time for the army to break through the Mojia defense on the Yishui side.

However, under the feudal system, who stays behind to defend it? Where can there be such an organizational force that can leave behind an army that will not retreat?

In the face of the reality of the Battle of Nanjishui, who can hold it?

Unable to hold it, tens of thousands of troops were chased by the Mo family from behind, intercepted from Yingyi and Feiyi to the east, and intercepted in the Yimeng Mountains.

Counting on the reinforcements of Judi, it is difficult for Judi to protect itself, and if the reinforcements come, Judi is captured by the Mo family, what will happen to the logistics? Nearly 100,000 troops eat grass roots in Yimeng Mountain? I'm afraid that there will be no need to fight at that time, and the current organizational strength of the Qi army will definitely be scattered in a rush and difficult to control.

The battlefield situation is constantly changing, and the current situation is because Tian Qing chose the most suitable means before.

If Tian Qing had any attitude towards a comprehensive retreat along Yishui before, the Mo family would also take offensive means and annihilate the Linzi army in the Yimeng Mountains in Juxi.

On the contrary, because Tian Qing chose to shrink, the Mo family was unwilling to take the initiative to attack, but wanted to force Tian Qing to take the initiative to attack, relying on diplomatic pressure to sever the relationship between Qi and Lu and trap Tian Qing one day and have to attack.

Because of this, there is only one brigade of troops stationed in the mountains near Yishui, and it is not necessary to put all the troops there.

It's not easy to supply there. Moreover, only one brigade is enough there, the number of people is small, the Qi army cannot break through, and the two volunteer corps on the side of Liangfu and Fei Yi can also use their mobility to surround the Qi army on the march.

Now that the situation has changed, there are two possibilities that must be considered by the public metallurgical side.

First, the Qi army really fought to win the city, captured the win and returned to Linzi, and shrank its forces to fight the defense of Linzi.

Nagong Zaoye must attack north when the Qi army attacks Yingyi, seize the few cities under the Qi army, and cooperate with the appropriate side to form an encirclement.

The lack of troops on the right side is not enough to defeat the Qi army, but it is not enough to fight a war of annihilation, and now the initiative of the Qi-Mo war is in the hands of the Mo family, but the Mo family also needs a greater victory to obtain enough follow-up benefits.

Second, it is a fake that the Qi army won to the death, but in fact, it made a desperate bet to attack Qufu with light soldiers, and launched a coup d'état with the princes and nobles of Lu State, dragging Lu State into the war, relying on Lu State as the rear to continue to insist, in order to change the situation in the world.

This requires the public to divide a part of the army, keep an eye on the vicinity of Qufu, once there is a possibility of a coup d'état, or intelligence of the elite actions of the Qi army, immediately go to Qufu, as long as it can withstand a few days, the army in the direction of Liang's father is enough to annihilate the Qi army in the direction of Yingyi, and at the same time go south to solve the problem of Qufu.

These two considerations are not contradictory, but in addition to these two considerations, there is another point that is very clear in the mind of Gongzaoye.

That is the direction of Yishui.

In any case, the Qi army lost its mind in this battle, and it was already a certain defeat, and the only way to escape was Yishui, if it was not tightly tied there, the outcome of the Qimo War would not be a complete victory.

Either way, there is only one way to escape after failure.

Gongzaoye now has a main division in his hands, and there are some miscellaneous troops, counting the elite of nearly 12,000 people.

The rest are the people of the Fei country, and together with the Mojia volunteers, there are about 23,000 people in total.

The defense is more than enough, the attack is insufficient, and there is still a part of the troops on the eastern front staring at Juyi north of Langya, in order to cooperate with the Qi army of Juyi made by Xi Liu, but it cannot move on paper.

The brigade of the Seventh Division is now in the Yimeng Mountains, and if the Qi army really breaks out and flees on a large scale, it may not be able to stop it, and when the time comes, one more person who escapes back will be more disadvantageous for the future. But before considering the logistics, you can't be stationed there too much.

The idea that the two sides coincide is based on this realistic reality.

In the letter, it means to let the public make the metallurgy divide the army into two parts. One concentrated the warrior knights and foot knights, moving westward. Once there is a change in Qufu, it can be supported immediately, and the starry night can arrive.

The remaining heavy troops began to move towards Dongmuyi.

In the military tent, Meng Sheng's finger also pointed at Dongmuyi, which was still occupied by the Qi army at this time, and it was also an important city that the trapped Linzi army could control.

To the east of Dongmu is Yishui. To the west, it is Liang's father. To the northwest is the Qi army, where Pingyang is the heavy city.

Gongzaoye said: "As long as we win the battle, we can take advantage of the time when the Qi army sends troops to capture Dongmuyi, then we can worry-free." At that time, even if the Qi army was defeated and wanted to flee, it was locked within a radius of fifty miles. ”

"The north is Yingyi, the southeast is Mu, and the west is Liang's father. It can not only prevent the Qi army from escaping, but also support the operation on the right side, and form a complete encirclement of the Qi army. ”

"Yu Su's brigade is near Yishui, if the Qi army is defeated and flees, his brigade can finally be tightened, enough to make none of the Qi people escape."

At this time, the city was more of a supply depot and a heavy troop assembly point, so he didn't need to know Tian Wu's plan, but if he wanted to annihilate the Qi army, he naturally had to pay attention to Mu Yi.

Meng Sheng said: "If the Qi army is dispatched, those who stay in Muyi will be ten thousand." But we can't be impatient, we have to tie our pockets tightly, and we have to wait until the fight on the Yingyi side is fierce, and we can take it in one fell swoop. The Yingyi side needs to give us enough time to prepare, five days, as long as the Yingyi is not broken within five days, we can be in Muyi, and the appropriate side can also completely tighten our pockets and encircle and annihilate the Linzi army. ”

This five days is naturally not counted from today, but from the day when the offensive and defensive battle of Yingyi broke out, or five days after the day when the army of Qi arrived in Yingyi, set up camp, and began to form a formation.

Gongzaoye said with a smile: "Five days, I can hold it." We also need five days to capture Muyi, and that should be no problem. After capturing Muyi, the Qi army is a turtle in an urn and a fish in a gang, and there is no escape. ”

After laughing, he put the appropriate letter on the map, and several staff officers drew the contents of the letter on the map.

On the map, with Yingyi as the anvil, the Great Wall of Qi is the ground under the anvil, and further north is Linzi.

The army in Liang's father's direction is gathering and waiting for the opportunity.

Once the siege of Yingyi began, the main force of Liang's father maneuvered towards Pingyang, and captured Pingyang under the breakthrough of Yingyi, completely cutting off the rear road of the Qi army.

The cavalry of the Ministry of Public Metallurgy will be stationed in Qiuyu, and if there is a change in Qufu, they can go straight to Qufu.

Yu Su's brigade did not move in the Yishui area, as the last to contain the mouth of the Qi army.

The remaining main force of the Gongzao Metallurgical Department will attack Dongmu after the siege of Yingyi begins, cut off the way for the Qi army to flee eastward, and completely block the Qi army in a narrow range south of Yingyi.

This is the situation before Qi Mo's possible last battle and the plans of both sides, Tian Wu was not led by the nose, and Shi was not led by Tian Wu, because the strategic objectives between the two sides were not the same at all.

What is suitable is a war of annihilation, which completely makes Qi civil unrest, makes Qi completely weak, deters the princes of the Central Plains, and lays the foundation for the Mo family's southward expansion under the situation of the retreat of the Yue Kingdom to the south.

What Tian Wu wanted was to flee back to Linzi, lead the elite of private soldiers to launch a coup d'état, and wait for the princes to shake the world and mediate with various countries, as for whether the Linzi army was destroyed, it was not considered.
