Traveling to another world, inheriting a mess at the beginning

Aarons couldn't help much in either fighting or research.

So the only thing he could do was to study tactics.

"Although I didn't really learn any military knowledge before, I still read a lot of my father's books."

Before the birth of Marquis Moti's youngest son, the young master's situation was not so difficult.

The old marquis had also written a lot of military experience in the past, and the young master had basically read all of these things.

So Aarons now actually still knows some military knowledge.

"Most of the border territory is plains, and although there is only one passage leading to this side on the Kadia side, that side is a hillside that is easy to defend and difficult to attack. It is very difficult to deploy defense from our side."

When Aarons took out a map of the border territory and spread it on the desk, Yalu and Mo Qianyun also came up.

"My lord, are you going to make preparations in advance?"

Although Mo Qianyun can learn most things at once, there are actually certain limitations.

Because she was used to being alone, the faster she got the hang of things that could be done by one person.

She was not so good at things that involved many people, such as commanding troops or managing people.

"If possible, I would even like to bury carbon-uranium mines on the passages through which the Cadians enter the Empire... But the other side has not declared war yet, nor has any hostility towards the Empire, so we can't do that."

The Cadians are likely planning to fight the Empire without declaring war - if that's the case, Aarons and the Fourth Legion must be ready to fight at any time.

"But the consequence of not being able to deploy defenses in advance is that if the other side uses highly mobile forces to launch a rapid raid, it will be difficult for us to stop them on this large plain."

The main tactic that Marquis Moti relied on to defeat the Cadian Collins coalition was the bait tactic - using supplies to attract the main force of the coalition to come and rob, and then taking the opportunity to sneak attack the other side's camp garrison and logistics troops.

Due to the limitations of the terrain, the coalition's logistics supply line is actually quite long. Marquis Moti took advantage of this weakness and made the coalition fall into traps several times.

When the coalition forces, which lacked supplies, came to the decisive battle in anger, Marquis Moti would use highly mobile troops to consume the morale of the enemy in a hit-and-run manner.

After failing to defeat Marquis Moti in four large-scale frontal battles, differences arose within the coalition forces. Because the Principality of Corinth took the initiative to negotiate peace with the Empire in private, the coalition forces were eventually forced to disband, and the Cadians who lost the war paid a large amount of war reparations.

Marquis Moti became the lord of the border territory after the war, and he took the initiative to hand over all his military power after the Empire's air battleships were put into service.

"The old marquis's tactics are no longer effective. At that time, there were not so many cities and towns in this territory, so even if the coalition wanted to find supplies, there was nowhere to go... But now there are a lot of supplies in these big cities. They only need to break through one or two of them to establish a solid bridgehead."

In the past few decades, a large number of cities have been built in the originally desolate border territory, and the total population has long exceeded one million.

Although this is a proof of the prosperity of the empire, it is actually a potential risk.

"Well, can the people be evacuated with supplies in advance?"

"Impossible, the reason is still the same as before - there is no official war now, and the relationship between Cadia and us is still normal. If I say publicly that they intend to invade now, no one will believe it."

However, Aarons estimated that the Cadians would not really attack in a big way. What they need most is actually the trade route to Corinth on the edge of the mountain.

There are three cities near this route - in addition to the city of Moti, which is stuck in the middle of the channel like a wedge. There are two cities built near Cadia and Corinth respectively.

"I guess the Cadians will launch a large-scale attack at the beginning to make the Empire misjudge their intentions. Then they just need to take the opportunity to open this passage, and the Corinthians will have the opportunity to enter."

Once these three cities fall, Cadia and Corinth can rely on the cities to build a solid defense line. The Empire may need to send several times the military force to have a chance to recapture these key areas.

"If these cities are lost, they can deploy a large number of magic array cannons. At that time, even warships will find it difficult to approach the city."

The defense of the air battleship is not as strong as it seems. Due to the large amount of alchemical materials used in the structure, once the external defense is penetrated, the internal structure will be severely damaged.

The outer defense of the battleship is actuallyIt is only about level 4 in terms of level 4 - and when the defense array is activated, the firing rate of the ship's guns will also be seriously affected.

"Although the Yumenhua has replaced all the magic array guns with carbon uranium cannons, it can't withstand the continuous attacks of dozens of level 4 magic."

"Then... what should we do now?"

"The Fourth Legion has now deployed most of its troops in the cities of the two neighboring countries, and I am considering using Moti City as bait to attract the Cadians to attack first."

If the Cadians really only occupied Moti City, they might be sandwiched by the north and south and the imperial reinforcements... but this strategy is actually a bit too idealistic.

"The strategies I just mentioned are actually based on the premise that the Cadians only want a trade route. If the other party's appetite is bigger or there are other goals, then this strategy will not work."

Considering that the Sunset Kingdom in the south of the empire is aggressively invading the empire's border, if the Cadians intend to echo the front line over there, then the empire may find it difficult to resist the rapid attack on both fronts.

The final intersection of the two invasion routes happens to be the most important magic source stone production area in the empire - the Dukedom of Booker.

"If the appetite of these two families is really that big... then it will be troublesome."

Since there are still people among the nobles who are secretly communicating with Cardia, if a noble suddenly turns against the empire when it is attacked on two fronts, then even the imperial capital may be directly threatened.

"We must have a countermeasure that can strongly resist the attack of one side, and we only have the Prison Gate Flower in our hands now... um."

Although the current situation is still unpredictable, Aarons has actually thought of a way.

"I have an idea. Qianyun, help me write a list of requirements now, and then give it to Teacher Jiangyue immediately... We must complete the transformation of the Prison Gate Flower as soon as possible."

"Yes. But my lord... what do you plan to do with the Prison Gate Flower?"

"Strategic deterrence."
