Reincarnated as the Demon King's Son

The students walked with wobbly legs and helped each other from falling to the ground.

When they reached their resting area, they started to feel pain all over their body. Aldred's training was brutal and vicious. Just like the name of the training, this training was inspired by Spartan history that he had read.

Children of Sparta trained since they were a child. Punching each other was a daily occurence. Each Spartan warrior was an elite of itself and was said to be worth 5 ordinary men.

Whoever is raised in Sparta would have mental toughness unlike any other.

Aldred noticed that his students were a bit spoiled. They had the ambition, but their will wasn't enough. At first, he wanted to take things slow and steady, but Biran, the teacher of A Class, pissed him off.

If not for that, he would only tell them to do mild training. Though he had to admit the children of A Class were incredible.

He had analyzed them with his godly eyes and could tell that they had higher life force than normal children at their age.

Aldred watched his students in the resting area eating a boxed lunch that their parents had prepared.

Aldred decided to be a little cruel. Not just because he wanted to be cruel, but because he wanted these kids to really have the mindset of a warrior.

"Students! Come forth!"

"Master, we haven't finished our food yet."

"Are you disobeying my order?" Aldred asked.

The students immediately put their lunch boxes away and walked to him.

"Who told you to walk?"

The students started sprinting and gathered in front of him.

Aldred frowned. "Organize yourself! You're a soldier now. Get in formation!"

The students quickly entered into a proper 4 by 6 formations.

"When I told you to gather, I wanted order, not a bunch of mess like earlier. Do you understand?"

"Yes, Master!"

"Good. Now, for your next training." Aldred opened up a portal and a bunch of fighter golems came out.

The students were surprised that their teacher could open up a portal with a wave of a hand, but they did not dare to ask questions.

"Do you know what these are?" Aldred asked.

"Uhh, training dummy?"

Aldred laughed. This was the first time someone called his fighter golems a training dummy. Anyone that had fought one of his golems would tremble in fear when they see one.

Not only were they almost indestructible, they were also unstoppable.

"These are not training dummies. These are my fighter golems. Let me show you what they are capable of."

Aldred waved his hand and a screen appeared that showed his golem army swarming into a city and took it in less than a day.

The students looked in amazement when they saw the golems cut the enemies apart without mercy.

But after the recording was over, the students trembled because of what Aldred said next.

"I want all of you to fight my golems."

After watching that video earlier, and understanding the true power of these golems, the students couldn't help but shake when they looked at these 2 meter tall hulking warriors.

"Master, how can we possibly fight these golems?"

"Your task is not to defeat them."

"Then what is our task?"

"All you have to do is to be on your feet as long as possible. I don't care if you dodge, run, or attack. For 30 minutes, I want you to survive against my golems. But my golems won't use their full power."

The students sighed in relief after they heard that. If the golems used their full power, it would be a massacre.

"Now get ready!"

The students tensed up.

Aldred glanced at them. They were sweating on their forehead.

"FIght!"

The golems rushed forward while the students ran away immediately.

Aldred smiled. He knew they would run away immediately, so he specifically told the golems to hit those who run away harder.

The golems raised their wooden swords and slammed against the children's back. They were thrown a few meters away and then rolled on the ground.

"Never show your back to your enemy! This is your lesson!"

"Ahh! My leg!"

Aldred saw one child had his leg snapped. He immediately used his Blood Manipulation spell to control the bone, and muscles within. In a blink of an eye, he snapped the leg back in place.

"If you don't want your leg to be broken again, stand up and do something!"

For 15 minutes straight, the golems beat the children left and right. It might look cruel from outside, but it wasn't that painful. The golems controlled their attack, making the pain to be a little bit more powerful than a spank.

Of course accidents sometimes happen and kids were thrown here and there, some legs snapped, and bones broken.

But that was normal and Aldred could fix those types of wounds easily.

After 20 minutes, Aldred told the golems to stop and saw that none of the kids managed to keep standing.

They all fell on the floor while breathing heavily.

"Rest for 15 minutes. We will begin the next round after that."

"Master, this is too much."

"Do you guys want to win?" Aldred asked.

"We do, but there has to be a better way. Why don't you improve our technique instead?"

Aldred shook his head in disappointment. "You have wealthy and powerful parents, yet your mindset is still that of the poor."

The students didn't know what to say about that comment.

"You think life is easy? You think there's a shortcut to everything? If you want to win, you have to suffer more than your enemy. While your enemy is sleeping, you run until your legs give up. While your enemy is sitting and eating, you push your body until you cannot move."

The students listened intently. Their eyes lit up when they heard his speech. Suddenly, all the pain they had experienced today was all more than worth it.

The more pain they feel, the more they think that they are one step ahead of their enemy.
