The portable grandfathers that appear are all problematic.

“My world has already caused too much killing, and I don’t want to create more suffering. Hatred will end after my generation ends,” the old demon king said. “I just abolished their identities and made their descendants come to my side as hostages. This way, I can resolve racial conflicts by cultivating the next generation.”

Xue Law: "..."

Hmm... he could probably guess how that empire fell.

Oh, it's that nagging mother-in-law. Sorry to bother you.

Seeing Xue Dinglu's barely concealed expression, the old devil asked, "Is there a problem with my plan?"

Yes, that's a big problem! You're completely disregarding the other side. Do you think you can make them obey you just by using protons?

Xue Dinglu hesitated for a moment, then said politely, "Your question is very big... Generally, in this kind of rule, the previous leaders usually have to be wiped out before a period of peaceful rule can be achieved. Otherwise, the power of the remnants of the old regime to restore it will definitely be much greater than you imagine..."

Seeing the old demon king's attitude, Xue Law continued, "Didn't you have similar stories in your previous history?"

"History? Sorry, we only record the history of hatred when we go there. Besides, I was the first in the world to achieve unification, so I have no history to refer to. I can only take it one step at a time." The old demon king said, then asked Xue's Law, "How long can your methods maintain peace? By killing all the nobles?"

"Well, I guess it can last until you die." Xue Law gave a somewhat conservative conclusion, summarizing based on his own historical experience: "It will probably maintain peace until you die, but who knows what will happen after that."

"Then there's no need for that. What I need isn't this fleeting and false peace; what I want is a world of eternal tranquility for everyone. In my original plan, just five generations of this gradual, subtle process would be enough to completely eliminate the barriers between all races..." The Demon King continued, outlining his grand vision.

"I can easily suppress them with my own hands over five generations. And after five generations, when the new generation is used to peace and multi-ethnic coexistence, with countless bloodlines mixed together, how much racial hatred will they still have?"

Xue Dinglu immediately fell silent.

He suddenly realized that the old demon king's plan wasn't so bad... no, it should be said that it wasn't a problem from his perspective. His strength was enough for him to make such a long-winded plan, a plan that would take several generations to see results.

However, given his strength and lifespan, this plan was not a major problem, at least from his perspective of taking things one step at a time.

However, Xue's Law still disagrees. In such situations, one cannot be so sentimental and fussy. One must act decisively and eliminate the entire aristocratic class. Then, after brainwashing the remaining people for several generations, the problem should be solved.

Xue Law wanted to hear more about what this nagging woman would do next.

As expected, the story unfolded exactly as Xue's prediction had predicted. The remnants of the old regime were dissatisfied with the Demon Emperor's rule, so they caused trouble on the surrounding borders. Then, someone persuaded his youngest son to do something that defied logic.

The Demon King's youngest son, originally a prince, secretly plotted to usurp the throne while his father was dealing with issues at the border, and in an instant, he wiped out the entire group of "intellectuals" that the Demon King had left behind to govern the country...

One point to note is that the leadership team left behind by the old Demon King consists of outliers in this war-crazed world. They are a group of people who don't want to fight but only want to study knowledge and learning, because there are too many war-crazed people in this world, and everyone is a madman who kills other people's entire families.

He felt that if those war-mongers were put in power, the empire would be doomed, so he simply found a small group of cultured people who studied history, politics, astronomy, geography and so on to start governing the country.

Although things went wrong at first, after 14 years, this group of people managed the empire quite well and gradually got it on the right track. In fact, in order to protect these people who didn't have much fighting ability, he specially sent a large number of combat guards to protect them.

But shortly after things seemed to be on the right track, his youngest son usurped the throne, killed all his brothers and sisters, even his mother and stepmother, and then, with the support of those warmongers, wiped out the entire group of intellectuals...

That's not all; he also secretly plotted to release the other hostages who were nobles, promising them fiefdoms and the possibility of becoming vassal states in exchange for their release...

Upon hearing this, Xue Dinglu's vision went black.

Good heavens, really good heavens...

"Where's your teleportation portal?" Xue Dinglu complained.

"My personal guards have all betrayed me and joined my son's side, and those who could still relay messages to me have been killed." The old demon king closed his eyes and said, "This is the third mistake I made. I overestimated my subordinates. I didn't realize that in their minds, it was an insult to be ruled by powerless scholars..."

"So long after this incident, I was unaware of the situation in the capital. The messengers who kept sending me messages told me that everything was normal and the entire empire was thriving. So I delegated the authority to directly suppress the rebellion in another place."

Xue Law: "..."

Steam! Keep steaming! Civil officials managing military generals—this was an idea devised by the old devil with astonishing wisdom. He even sent many war fanatics to protect the civil officials, but who would have thought that they would all turn against him and wipe out the political team he had painstakingly cultivated.

Xue's Law seems to have lost its spark of wits. Isn't this something you can easily figure out by thinking about it? Why don't you look back at history and see what our predecessors did...?

Oh right, he can't change history; he was the first person to unify the country...

Xue Dinglu was speechless. He had found countless problems in these operations, but these problems were not really problems in terms of the old demon king's strength and lifespan. However, it was these small problems that accumulated and caused unimaginable consequences.

“Then, there was my fourth mistake.” The old demon king closed his eyes, and Xue Lude saw vicissitudes and incomprehension in his pupils. “I trusted my youngest son too much. He pretended that nothing had happened, and then he stabbed me with the back of a knife stained with the blood of the Zerg.”

"It's that 'Shabu Insect Clan' blood you mentioned. It's something that I could easily get hurt by if I'm not careful. Because of my trust, I was careless and the toxin had its best effect in a short time."

"Even though I've cleaned the bugs out, for some reason they still have that blood on their hands."

Xue Law: "..."

"What's he after?" Xue asked. He still couldn't understand what his youngest son was after.

Is he after the throne? Because he is the youngest son and has no right to inherit, he might as well kill all the other heirs and become the sole heir? Then he gets scared afterward, so with the help of others, he plans to kill his father?

He couldn't understand it. Xue's Law really couldn't comprehend the behavior of an idiot. At this moment, he felt as if he had seen the end of the universe, and his entire CPU was smoking.

Chapter 211 Don’t make noise, I’m thinking

"Yes, everything I've done has been in vain. My hundreds of years of effort have vanished in this moment..." the old demon king continued.

“Betrayal by family, betrayal by confidants, betrayal by the country, betrayal by the people… everyone has turned against me.”

The old demon king gazed at the light source emanating from the space above his consciousness and sighed: "I ended the ritual of blood sacrifice to heaven and earth. It was an evil ritual that required the blood sacrifice of living people to gain power. I forbade it, and then I was despised by the people."

"I put intellectuals in charge of those warmongers who only knew how to kill, so my confidants betrayed me."

"I gathered all the combat magic in the world and then vigorously promoted life magic, including bridge-building magic, soil-turning magic, rain-making magic, and other spells that could clearly improve people's lives. But they only thought that without power in their hands, they would only be slaughtered by others..."

Xue Law: "..."

Too much wisdom has been extinguished. Xue Luding looked at the old demon king. Although his problems were significant, many of them were not really problems from his perspective and strength. However, these problems had accumulated and were about to explode.

At the same time, it can be said that every step he took was problematic.

Xue suddenly realized something. This old devil was like a madman who was far beyond their world's era. When this madman wanted to implement policies that were far beyond the current era, even if these policies were good, they would definitely become bad policies.

Commonly known as: taking too big a step, dragging things down below...

It's like their world wasn't even a slave society to begin with; it was practically a primitive society. And then this old demon king suddenly wants to jump from a primitive society to a feudal society...

Those old fogies still living in the primitive society haven't died yet, and people's ideas haven't even changed, yet he started a sweeping, top-down reform, bringing about a complete transformation.

Although Xue's Law understands that harsh measures are necessary in chaotic times, taking such a big step suddenly puts everyone in a state of anxiety and unease, and naturally, all the small problems accumulate and then explode.

He wanted to speak, but upon seeing the old demon king, he was speechless.

Xue's law suddenly felt normal.

This old demon king was basically illiterate. He went to the battlefield at the age of 6, became a legend at the age of 12, entered the mythical level at the age of 28, and then, in his 50s, he killed the original demon king by himself, seized the throne, and began to single-handedly destroy the entire world.

He spent his entire life either honing his skills or fighting, from the age of 6 until he was over 100 years old. He killed tens of thousands, if not millions, of people, until everyone in the world had to listen to him.

However, such people really don't have much time to learn about culture, and the culture in their world is just so-so; they are all a bunch of madmen who can't survive without fighting.

War should have spurred technological advancements, but in their world, technological development had been entirely focused on creating more ruthless killing magic and figuring out how to kill with the least amount of magic power at the highest efficiency…

Regarding murder and how to efficiently kill an entire race, their world's "technology" is, in Xue's opinion, the most advanced, even surpassing that of the Super Iron Curtain...

He had no history to refer to, so he could only take it one step at a time. Many times he doubted whether a step was right or wrong, and he could only know whether he should have taken it when the result came out.

Xue also understood why his confidants betrayed him: because he had the most power and they could get credit by following him, so they were willing to follow such a devil. But after he unified the country, this military machine had to come to an abrupt halt, and all the original war fanatics were abandoned.

These people, who were originally heroes and pillars of the nation, suddenly became unwanted. This huge drop in status is not something everyone is willing to accept.

Those war fanatics are definitely going to be furious. They didn't dare cause trouble when the old demon king was around, but now that he's gone, it's hard to say.

……

Finally, the old demon king sighed, "I don't understand. If everyone just farmed and raised livestock, there would be a peaceful world where everyone wouldn't have to go to war at the age of six, and everyone would have enough to eat and wear. Why do they insist on giving up their peaceful lives? Why do they prefer to return to that era of endless war..."

"Similarly, why do they worship such an evil power as blood sacrifice? Do they only think about being the beneficiary of the blood sacrifice, rather than the one being sacrificed? I don't understand..."

The old demon king's words revealed the confusion of an illiterate man.

He seemed to genuinely believe that as long as he provided everyone with the opportunity to be well-fed and clothed, no one would want war.

But the truth is that he made sure everyone was well-fed and clothed, but the entire empire began to collapse from within, and the speed of the collapse was astonishing. Similarly, those who were well-fed and clothed instantly turned against him.

"So, I am seeking a way to achieve lasting peace and tranquility. Since my first path has failed, I am still young and have the opportunity to pursue the second path to lasting peace." He did not seem to have given up, but now he seemed to have lost himself at the crossroads of life and could not find his way in the future.

Xue Law: "..."

Did this old demon king suddenly have a change of heart? He didn't rush back to his own world, no matter how raging the floods were there; he only wanted to continue seeking a way to achieve eternal peace.

However, eternal peace is impossible. Xue's Law can guarantee that as long as living beings have "desires," eternal peace is impossible to achieve. The times are progressing in a spiral, and new things will inevitably replace old things.

However, conflict is inevitable during the transition between the old and the new.

This was the content from the book that Xue Dinglu had just finished studying. He didn't know how to explain these theories to the Demon King, and he even felt that he was not qualified to talk about these grandiose and empty principles.

After all, he was just a stupid college student who had never actually managed a country. He might be good at theory, but when it came to practice, he was just a big talker and not even as good as this old devil.

"Ring ring..." Just then, the school bell rang.

Xue Luding then realized that he had been chatting with the old devil for too long. Unless something serious happened, he was still willing to act in accordance with the duties of a student.

However, the old demon king was stunned when he saw the college students chatting and laughing and running in the corridor.

"You don't have any magic here?" He saw the problem at a glance.

“Yes, the entire world is absolutely devoid of magic, but we have embarked on an alternative path of magical technology.” Xue Dinglu shrugged. After all, Blue Star’s technology is essentially an enhanced version of magical technology, so he wasn’t wrong.

Xue Dinglu hurriedly put on the mask that the Faceless One had transformed into and returned to the classroom.

On the podium, the old professor began to speak: "Students, turn to Chapter 4 of your textbooks. Today's topic is establishing correct values. Pay attention, this is a must-know point for the final exam, and it will also be a must-know point for all your future exams, whether it's the postgraduate entrance exam or any other exam!"

The teacher's words immediately made all the students who were about to play on their phones or sleep sit up straight. Although many people relax after entering university, it is still a key university like USTC, and many of them at least have the idea of ​​making a name for themselves.

However, Xue Dinglu didn't care about this part of the knowledge at all. He had already learned enough about this when he taught Fafnir, to the point that he could roughly memorize the key points of the text.

With the added memories of the doctor from the parallel world, he felt incredibly strong, the kind of person who could easily pass the USTC entrance exam for graduate school.

Just as Xue was about to chat with the old devil again, he discovered that the devil was listening very attentively to the teacher's lecture on the podium. He even had a scroll in his hand and began copying down a large amount of knowledge points.

"No, you..."

"Stop arguing, I'm thinking. This is invaluable knowledge. We can talk about anything else later," the old demon king interrupted immediately without any politeness.

Xue Law: “?”

He suddenly realized something. Although they were both near-5th rank, the Great Sage had traveled to countless worlds, seen all kinds of civilizations and knowledge, and collected countless cultures and learning. He was like a walking library. Therefore, the Great Sage had an indifferent attitude towards everything on Earth.

The Great Sage has visited more than one world centered around magical technology.

However, the old demon king was different. He was completely illiterate, and his entire life was spent either fighting or on his way to fight. Moreover, the knowledge and history of his world were shockingly lacking.

All the knowledge basically points to how to kill more efficiently.

Therefore, although they are both near-5th rank, the difference in their vision and perspective is enormous. Even if this doesn't affect their strength or the power of their punches, it has a huge impact on their inner selves.

Just like now, the old demon king seemed to have discovered some treasure. He listened to the teacher's lecture with great focus, and his notes flew across the page, not missing any knowledge points or words.

Even when the teacher deviated from the textbook and blackboard and began to tell a short story from his own past to support the knowledge points, this old devil wrote down every single one of the teacher's classroom anecdotes.

Even every sentence and every point of knowledge was marked with his own understanding and thoughts. In an instant, a scroll that was originally blank began to be densely covered with text and his own annotations.

Xue Law: “???”

Even after half a class had ended, during the break, the old demon king was still writing furiously. He even put down the scroll and began to inscribe characters in the void, recording all the knowledge of the outside world. His pupils were filled with those recorded characters.

"Alright, what did you want to say just now?" The old demon king seemed to have finally finished recording and said.

"Actually, you don't need to take notes. I have as many as you want..." Xue Dinglu snapped his fingers, and a textbook appeared in front of the old devil.

Then with another snap of his fingers, all the textbooks—philosophy, history, moral education, general knowledge, and so on—appeared and scattered on the ground…

He used his imagination to create many copies of these books and stored them away. Every morning for breakfast, he would use bread magic to turn one of the books into bread and eat it, letting the power of knowledge flow into his stomach.

The Old Demon King: "..."

The air suddenly became quiet.

He silently picked up the book from the ground, holding it in his hands as if it were a precious treasure, an attitude that made Xue Dinglu feel uncomfortable.

What they could find easily was more precious to the old demon king than any divine artifact.

"In your world... is knowledge that can easily overthrow the old dynasty just distributed so casually? And when I saw those people, they showed absolutely no urgency or tension, their demeanor was completely different from the people in my world..."

"Is your world a peaceful world? Then can you tell me how to achieve eternal peace?" The old demon king looked at Xue Luding, and something called "ambition" seemed to reignite in his pupils.

Chapter 212 I Don't Even Know the End of the Universe

Xue's Law really can't answer this question.

This is far too grand a concept for Xue's Law to consider; he has never even considered "peace."

He doesn't even know the end of the universe, so how could he possibly know such a difficult question as eternal peace?

After saying that, Xue Dinglu still relied on his path and wanted to pick up his phone and start playing "Ultraman Tiga," which was said to be the most effective way to soothe old men. However, he suddenly hesitated.
