Tor Charles bought a bunch of books in Abyss City, and Elizabeth didn't suspect that Charles had traveled through time, just that he was smart and clever, and learned a lot from those books.

Over the next few days, Elizabeth grabbed Charles into the room and discussed with him about this "flex cage defense tactic".

Charles did not think that he was smarter than Elizabeth, who had lived for hundreds of years, and Elizabeth had apparently thought about the same tactics, and saw many details clearly than Charles, and she only took the opportunity to educate Charles in the discussion of the issues.

The day before she was ready to arrive, Elizabeth sat at her desk and talked to Charles. Elizabeth often used these conversations to teach Charles anything other than magic.

"The law of war is a problem that anyone who directs war cannot fail to study and solve. Elizabeth said to Charles, "You see, whatever you do, if you don't know what it is, what it is, how it relates to things outside of it, you don't know the laws of that thing, you don't know how to do it, you can't do it well." ”

Then she asked Charles, "Tell me, what do you have in common and characteristics about the millennial war between humans and the Rurik Kingdom, the war between the Rurik Kingdom and the demons, and the war between your grandfather and the Bischberg Kingdom?"

Elizabeth's room was much more luxurious than Charles's small studio, with an en-suite bathroom and a small study. Charles, who was sitting at his desk in the study, tapped his fingers on the table as he thought.

After a while, he said, "War is the continuation of politics, and the economy is the foundation of politics, so it can be said that war is to serve economic interests." ”

Elizabeth nodded, motioning for him to continue.

Charles thought about it in light of what he knew about history, and said, "The war between mankind and the Rurik Kingdom can be seen as a struggle for land, an important economic resource. After a long war, the humans seized the land that originally belonged to the kingdom of Rurik in the eastern part of the Limhi. ”

"The same is true of the war between the kingdom of Rurik and the demons, where the two sides fight for the land on which they depend. ”

"The same is true of the war between my grandfather, Duke Redkin, and the Kingdom of Bischberg, except that Duke Redkin needs to gain not only economic benefits from the war, but also political benefits built on it. ”

"Compared to this, the war between the Rurik Kingdom and the demons and humans is much simpler. ”

Elizabeth nodded in satisfaction, "It's good that you can answer this point at your age." ”

She went on to say, "The war between us elves and the fish-people of the south is a war for purely economic gain, and the so-called justice is only an accessory to interests, and you are the justice of whoever you bring benefits. ”

"Because of the harsh living environment in the sea, the fish-people are facing great pressure to survive. The Fish-People have always wanted to acquire fertile coastal land as their own food source, and we need to protect our own property. ”

Charles doesn't ask why the dispute between the two sides is not resolved through trade, because the fish-people in the east have already made peace through communication, so the conflict between the elves and the fish-people in the south cannot be solved by trade.

Moreover, the fish-people are not good at farming, and when they acquire farmland, they will only become a slave-owning class, and the defeated elven natives will become slaves who will cultivate the land that previously belonged to them.

Now the elf and the fish-man to the south are like the farming and nomadic people of his previous life, and life in the sea is much more difficult than life in the steppe. Before the Makqin heavy machine gun, the wool textile industry, and the modern animal husbandry industry came out, the contradictions between the two sides were irreconcilable.

Elizabeth took a sip of tea and said, "Different wars have different characteristics and rules. Therefore, we should study the laws of general warfare, we should also study the laws of resource wars, and finally, we should also study the laws of resource wars between our elves and fishmen. ”

"For example, we elves can't live underwater, so we can't occupy the land where the fish-people live. But fish-people can live away from the ocean for a long time. This is different from the three wars just mentioned. ”

"Therefore, our war against the fishmen is based on the living force that kills and injures the enemy. ”

"In this war, violence will be used to the fullest, and the goal of using violence is to make the enemy unable to resist. The enemy's resistance is the product of his existing strength and his will to fight, and we must completely destroy one of the enemy's aspects, preferably both. ”

Charles, who can only talk on the keyboard, records what Elizabeth said while recalling what he knew in his previous life, and the two corroborate each other and learn from each other.

After a while, Charles felt a chill on his body, and he heard Elizabeth say murderously, "In this battle, we will kill the fishmen and the blood of the rivers will flow, every family will wear filial piety, and every household will be funeral." ”

At this time, Charles remembered that the fairy in front of him, who was as beautiful as a fairy and often died to Aunt Artoria with him, was a real princess, and in the future, she would be the role of "the wrath of the Son of Heaven, ambushing millions of corpses, and bleeding thousands of miles", rather than some harmless white rabbit.

The door was slammed open, and Artoria rushed in. She breathed a sigh of relief when she saw Charles and Elizabeth looking at her blankly.

"I felt the murderous aura. Artoria retracted the sword in the stone in her hand, "I thought you were going to kill Charles." ”

"Why should I kill him?" said Elizabeth, confused.

Charles, who is smart, well-behaved and cute, nodded along the way.

"Who knows?" said Artoria with a smirk at Charles, then turned away.

The people and elves in the room looked at each other, and they couldn't understand what this aunt was doing.

After the door to the room closed, the two returned to teaching.

Elizabeth took a piece of parchment and gave it to Charles, "Write down how to kill the fish-men for a hundred years of peace." ”

Charles sat there thinking for more than an hour, then spent twenty minutes or so writing an entire page in elven script.

Elizabeth was satisfied with it, and then took out a briefcase locked with a lock from her storage ring, opened it, and took out two pieces of paper from it and handed it to Charles.

"You can take a look at this. She said.

When Charles took the two pieces of parchment, he saw that the title read "Plan No. 2."

It took him a long time to read the battle plan that Elizabeth had drawn up.

The core content of this plan is exactly the same as the plan he just wrote, which is to deliberately leave a flaw to induce the enemy's important figures to lead a large army to break through alone towards an important target that can change the direction of the war, and then use the mobile advantage brought by the road network to form a superior force to surround it, and finally continuously consume the enemy's vital forces who come to the rescue through "siege and reinforcement".

It's just that Elizabeth used an extremely important logistics base as bait, while Charles played bigger and directly used Elizabeth's mother as bait.
