Reincarnated as the Demon King's Son

"Thinker?" The bandit laughed. "What a stupid name. Now pay 50 gold coins if you want to climb the mountain."

"I do not have 50 gold coins with me," Thinker replied with a slightly robotic voice.

"If you don't have it then piss off. Wasting my time." The bandit spat on his feet.

"Piss off? My human translation core tells me that you are telling me to go away."

The bandit raised an eyebrow and looked at his friend. "Is this guy an idiot?"

"It is the fourth time I have been called an idiot. I wonder why they said that. Unfortunately, I never had the chance to ask. They all died you see."

The bandits looked at him. "Are you threatening us?"

"No, I do not. I merely stated a fact."

"There's twenty-five of us here, and only one you. I don't have time to handle your poor ass. Get the fuck out of here."

"My master ordered me to obtain the treasure. For that, I need to climb this mountain."

"Then pay up."

"I don't have the required item for your permission."

"Then how do you want to solve this?" The bandit grinned.

"Processing… Complete. My information core has devised a set of steps to reach my goal in the most efficient way possible. And the first step is to eliminate all of you."

The bandits laughed. They laughed until a bulled lodged in their necks. The bandits gasped for air as they held their throats. Blood pouring out.

"Obstruction eliminated. Proceed to analyze the next step… Complete. Activating Climber Module."

The clothes on his back ripped open as thick mechanical limbs came out. The spider-like limbs stabbed the wall and lifted Thinker up.

"Detecting sentient beings…. Labeling… Competitors. Solution: Become faster. Activating Jet Pack Module."

Flames came out of his legs and back, as the spider limbs quickly walked on the wall, creating a bunch of holes.

When Thinker reached the group of people, a notification came. "Insufficient fuel."

The jet pack module shot out steam before it made a clicking sound releasing itself from his body and falling to the ground.

"Is that a robot?" Aldred asked.

"What's a robot?" Mary looked at the man.

"That thing. He literally has mechanical limbs and jet pack on his back."

Thinker turned his head and looked at Arthur. "Detecting powerful human… Conflict is not advised."

"He even talks like a real robot."

"Ignore him," Bartrem said. "We have a mountain to climb." He walked on the vertical wall with his Lashing Shoes.

Thinker saw the shoes and his eyes spun with red light. "Scanning… Scan complete: magical item. Mechanization: none."

Joseph stabbed the wall with his iron nail and pulled himself up, before stabbing the wall again using his other nail.

Mira weakly stabbed the wall as the wind blew. Her arms felt strained. Sophia took a deep breath and climbed.

"Mira, Sophia. You two are magicians. You can take a rest," Aldred said.

Mira and Sophia nodded and pulled their iron nail out. They put the nail on their pouch and crawled on the wall. They did not fall because of the Light Formless Chain. So long as one person was still on the wall, he could save the entire team. So they crawled on the wall to prevent the rock from scraping their skin. The ones that lifted their body up was everyone else.

Thinker's eyes gleamed in red again. "Very interesting. Recording… Finished."

A loud screech came in the sky. Everyone stopped and turned around. It was a gigantic eagle with a wide span of wings. It stared at its target and snatched a person from the wall.

"Ahh! Help me!"

"How can that beast fly?! No one shouldn't be flying in this place."

"It's the native monsters. They can do whatever they want here."

More eagles screeched and flew, circling the mountain. One dove down and grabbed a man. Its claw was bigger than the man's whole body.

"Stupid bird!" The man stabbed the creature's belly, but the sword snapped.

The bird flicked its head down and looked at its prey who was locked by its claw. It screeched in anger and then squeezed.

"No! Help me!"

The sharpness and the pressure of the claws cut the man into pieces. His remain fell as the bird turned for another prey.

"Shit!" Aldred said. "There's more of them coming. We have to be quick!"

The eagle noticed Aldred's group and dove down.

"No, you don't!" Aldred shot two fire javelins at the bird. they went for its head, but the eagle rolled and easily dodged them.

"You think you can dodge my fire spell?"

Aldred then spammed the spell, creating rains of fire javelins that stormed at the giant eagle. The eagle stopped in mid-air and flapped its wing, creating a powerful wind that pushed all the javelins away.

The eagle roared and flew with incredible speed.

Sophia raised her staff. "Confusion!"

The eagle shook its head, and then slammed against the wall.

"A chance!" Aldred let go of the iron nails and leaped to the eagle. Landing on its massive back, he blasted a chunk of his flesh with flame jet, and ate it.

[Analyzing… success. You have obtained the gene for Giant Eagle. From now on, you can transform into this beast and use its racial attributes]

[Gene: Gargant Eagle]

-High Altitude breathing

-Blessing of Mount Fargon

-Keen Eyesight

-Low Wind Manipulation

-Hard Feathers

Aldred laughed. He kicked the wall and then transformed into a Gargant Eagle in the air. His wide wings spread like the wings of an airplane, and he soar through the sky as Bartrem, Mareona, Sophia, Mary, the soldiers, and even other adventurers stared at him with amazement.

"Hahaha." He flew near them and stabbed the wall with his sharp claws, making him stuck in place.. "Guys. Get on my back. I will bring you to the top.

Mary and the others didn't react too much to his transformation. They had seen him transform into a Giant Velobra before, so this wasn't new.

Arthur and his friends on the other hand couldn't believe what they saw.

"Did he just… transform into a giant eagle?" Hugo looked at the bird.

"Such an incredible ability. A shape shifter was rare, and the ones that can shift into anything is even rarer. That kid can shift into a giant eagle after he ate it," Jake commented. "Arthur, we have to befriend them. There will be a lot of powerful creatures in this mountain, and they can help us survive."

Arthur shook his head. "We're looking for friends to help each other, not someone to use and extort. That's not friendship. That's just us being a leech."

"We're not a leech if we help them as well. You're a hero. I am sure you can do something to help them."

Arthur looked at the giant eagle. "I will think about it."

The length of a Gargant Eagle was similar to that of an airplane. So even if more than seventy people rode on his back, they still had room for their legs. Unlike the seat of Economy Class.

When the bird took flight with tens of people on its back, the people climbing on the wall could only stare with envy.

"Fuck! Take me with you! I can give you money!"

"I am the son of a noble! I hid my identity earlier! Here's my insignia! Take me with you and I can give you land!"

Aldred did not care about them.

"Righty, Folks! This is your captain speaking. All I can say is tighten your seatbelt and enjoy the ride. Oh, if you don't have a seatbelt, then hang on tight. Because things are about to get real."
