My Beautiful Disciples, I'm really not the Main Character!

Eren closed the door and walked to the center of the room. He placed the crystal that was given by Xiu Ying on the floor.

He placed his foot on the crystal and crushed it under his feet. The crystal shattered into a fine powder which dispersed in the room.

Eren felt his head spinning, as his perception started changing. The space inside this room appeared to change as his bed moved farther away from him, along with the walls.

His very reality seemed to be transforming before his eyes, leaving him very intrigued. This kind of treasure was something really useful, but he hadn't even known about its existence.

He could only imagine how expensive this small crystal had been. It was only a one time use item, and the extended space couldn't be shifted to any other place. This space was fixed to his room forever.

"I owe her so much. So far, I've only been taking things from her. I really need to become stronger so I can help her instead..." Eren muttered, looking at the finer crystal particles disappearing from the floor.

After a few minutes, the space stopped warping. The space inside his room had become many times larger, enough to fit the entire Sea Dragon's body inside.

"Celeste, can you keep an eye on the outside? Although no one will be able to break through Xiu Ying's barrier, the Sect Master doesn't fall into that category."

"If you see that woman coming towards this place, alert me."

Celeste flew towards the window and sat there, keeping an eye on the outside. That was the advantage of having a house halfway up the cliff. They only had to guard one direction.

With Celeste as a guard, Eren felt a lot more relieved. He took a deep breath and opened his inventory to bring out the Sea Dragon's Corpse as well as the Memory Fragment.

"Hmm? That's right, I haven't checked the rewards for a long time."

As he opened the inventory, he noticed that there were many more sections in his inventory filled with things he hadn't seen before. Most of these new additions were the reward he had received previously.

"Is this... The last reward I had?" Eren smiled wryly as he looked at the latest reward.

He only remembered that the option had said he was going to receive a surprise gift from earth. He hadn't expected it to be something like this.

"How am I even supposed to use that thing here?" He scratched the back of his head, guessing the item just from its silhouette in a small inventory box alone.

He tapped the screen, and brought out the so-called surprise reward. An item materialized right in his hand.

"Identification."

He used his identification skill on the item to see if there were any changes or if it was the same as available on earth.

[Item Name: Mana Condenser]

[Category: Mana Weapon]

[Description: A modified weapon that condense mana to create bullets and shoot. The bullet's strength depends on the purity and compression of mana]

[Reminder: Can grow with the user]

"A Mana Weapon? Isn't this just a gun? Did the system modify a gun from earth? Whatever, it's better to have something than to not. At least it's not a limited use item."

He had a high Mana Stat, but he didn't have any skill that used mana.

Mana was a stat that was mainly used in the Northern Continent. It was said to be as useful as cultivation for the Necromancer Tower, as it powered all their spells.

Previously, it was just a wasted stat, but he had some use for it now.

"I will have to check its strength against Xiu Ying's barrier. But I don't have high expectations from it."

He discreetly tucked the gun into the waistband of his pants, ensuring it was securely hidden from view.

Although he hadn't used a gun before, he had always seen people in the movies keep a gun in style.

"This does feel cool. No wonder men like guns."

"Next should be... The reward for killing the Prince."

He brought out another item, which was more like a roll of a thread.

"Identify."

[Name: Thread of Marriage]

[Grade: Special]

[Description: A thread that binds someone's life with yours. The connected person cannot cause you harm in any way, as they would experience ten times the pain]

[To use the thread, the target must be within a hundred feet of yours, and you must think about them while throwing the thread]

[Once connected, the thread will disappear but the effects will exist]

[Once connected, the thread can't be removed until the target dies]

"This seems quite useful. So, if I had used it on the Sea Dragon Empress, I wouldn't have had to run? But wait, even if she can't directly harm me, what if she used others to harm me? I'm not sure about the limitations of this item."

"I think I'll need to save it for later and give it some more thought. It must become the most helpful thing for me."

He carefully stored the Thread of Marriage in his Inventory and retrieved the third item he had kept there.

A dragon's lifeless body appeared in the room. Even with the extended space, most of the place was filled with the dragon's corpse.

Looking at the carcass in his room, it truly felt surreal. This was proof that everything he did was reality.

"Dragon's Bloodline... Let's see how much reward you give me. Because of you, I had to make the Empress my enemy. So I hope you won't disappoint me, dear prince."

He brought out a dagger and started cutting an opening to enter the Sea Dragon's body. Before using the Memory Fragment, he wanted to become as strong as he possibly could. And getting a new bloodline was the last step in his quest.

"The flight skill or the transformation skill... I really look forward to the rewards."

After creating an opening, Eren stepped inside the Giant Dragon's body and started making his way towards the heart of the creature.
