Reincarnated as the Demon King's Son

Numerous fighter golems swarmed through the tunnel like a group of vicious ants. The enemies were caught off guard, and they were torn to shreds one by one.

"Where is our reinforcements?!"

"They will come in a few minutes."

"Fuck! The golems will overrun the tunnel in less than a minute!"

"Hold the tunnel! Hold it until reinforcements come!"

The soldiers raised their shields and brandished their swords, but their foreheads were drenched in sweat when they saw the emotionless golems staring at them with a pair of red eyes.

When the golems were a distance away, the soldiers were shocked.

"How is this possible! Those golems… all of them have rare treasures!"

The soldiers gasped in shock.

"Wait. Look at that spear. Isn't that our spear! Those golems stole our weapons and are using it for themselves!"

"Fuck! Some parts of our armor is on their skin."

Morale dropped low when they realized that these golems would kill them and use their treasures to the fullest afterwards.

"Should we retreat?"

"Are you crazy? Sir Tomkin will kill us. All we can do is fight. Raise your shields! Focus on the defense!"

The soldiers entered a defensive formation that they were trained to use against a charging infantry. This formation relied on the shields of the soldiers to interlock themselves side by side, while the soldiers behind helped in bracing the weight.

They were confident this formation would hold on for a while.

But that confidence was destroyed, torn to shreds by a hail of fire bullets.

BANG! BANG! BANG!

The fire bullets clanged against the shield a bunch of times before some of them pierced through and shredded the flesh of the soldiers.

Their screams echoed in the tunnel, full of despair and pain.

The soldiers behind couldn't even react properly as the fire bullets filled their vision and blasted their arms and legs.

"AHH!"

One soldier seeing this from behind wore a terrified expression. He saw his comrades being killed one by one like a butchered animal. His hands trembled, then he heard a sound of ripping flesh. He looked to the left and realized that his left arm disappeared.

"Ahhhhh!" He fell on his butt and that was when he saw something tall stepping in front of him.

It was a golem, raising its blade, and then swung at his head.

He saw the world was spinning a few times before his head landed on the ground. A few seconds later, everything went dark.

These attacks happened to all the tunnels, and no one could fight off the golem army.

Tomkin frowned when he received this report. He expected an attack in his tunnel, but he didn't expect to be attacked in every direction all at once. This was the first time he felt distressed so much by a problem.

"What should we do, Sir Tomkin?"

"Send the slaves to slow them down."

The officer widened his eyes when he heard that. The slaves that Sir Tomkin mentioned were ordinary people that were dragged out of their home and forced to work in the tunnel. They were pulled away from their home and family, and they were treated badly and barely given any food.

To send them to their death after years of slaving away in the darkness…

The officer trembled in fear. "Yes, sir!"

All the soldiers ran to the underground jail cell where they kept the slaves from walking around.

"All of you get out!" a soldier said.

"Are we finally free, sire?"

The soldier grinned. "Yes. You are all free now. Get out and go to the east."

The slaves all excitedly walked out of their cell with the thought of finally being free. A 67 year old man cried when he stepped out of the cell.

"I finally can see my granddaughter again. I wonder if she still remembers me."

"She will grandpa."

The old man smiled. "You should already marry her at this age, Ely. When we get out, I want you to ask her."

The young boy named Ely nodded with a smile. He was a childhood friend with Nia, the old man's granddaughter.

Ely had a great relationship with her grandfather, and so he already considered this old man to be his grandfather as well.

He always played with Nia in her house, but unfortunately he and her grandpa was taken into this tunnel.

But now all was good because they were about to be free.

At least, that was what he thought.

"RUN! We are not being freed! We are being killed!"

Fire bullets came from the distant tunnel where darkness hid numerous red eyes that stared at them.

He saw a lot of slaves being killed from the cross fire between the soldiers and the monstrosity within that darkness.

But then, the soldiers were told to retreat. The slaves wanted to follow them, but the soldiers shouted at them to stay or they would be killed.

They were terrified, but thankfully, the fire bullets stopped.

All of them were trembling in fear as something stepped out of the dark. It was a tall statue, walking on two legs with majestic armor and powerful weapons.

They were golems!

Ely was scared and he held grandpa's hand. When the golem was near, grandpa stepped forward.

"Don't kill this child. Take me instead. He has suffered enough."

"Grandpa…" tears fell from his eyes. He ran in front of the old man, and opened his arms. "Don't take my grandpa. Just take me!"

"Ely, what are you doing?"

"I am protecting you, grandpa."

"You are young and still have a lot to do in this world. I told you to take care of Nia, so step back and let me handle this."

"No. I won't. I am sorry, I cannot take care of Nia, but I will not let them take you."

Suddenly, the golem knelt down and dropped his weapon. "We are not here to harm you. We're here to save you."

The slaves all had tears in their eyes and they were relieved as they hugged their friends.

Ely was so relieved. He turned around before hugging his grandpa.

(Author Note: And then the golems pulled his sword and cut all of their heads. The end. This is a joke btw)
