Into The Portal: Monster Invasion

"This is inestimable!" Merlin exclaimed!

"What is it?" Miles asked excitedly. Was the passive ability Rayen possessed so valuable?

"This is a dimensional world. A dimensional world appeared in my body!" Merlin said ecstatically. He looked at Rayen with stars in his eyes. He wanted to kiss this young girl.

"Calm down. You scare her." Miles shook his head with a smile. It turned out to be something amazing. "What can you do with the dimensional world?"

"It seems like it is a passive ability. Unlike Rayen, I don't have full control over it, but I do have it in my body now, so I can use it to some extent." Merlin tried to explain but even he didn't know what his limit was. After all, he just created this inner world.

"Let me change to another power, so I can test it better." He said and dashed out of the room. He only came five minutes later.

"After I copied another power, I don't have a connection to the dimensional world, which means I cannot use it to store items, but there are things that can be used passively," Merlin explained with a frown.

"What is that supposed to mean?" Miles asked. He didn't understand, because Merlin could feel it while Miles could not.

"I can store energy or elemental powers into my inner world because they are still connected to me. But I cannot store items as Rayen does." Merlin further explained. Miles then understood the difference. Rayen had two powers, one-dimensional world, and second space elemental powers. She could control the bridge connecting the material dimension to her inner world thanks to her powers. So, Rayen's active superpower should be something related to wormholes. But Miles wasn't sure yet, and Rayen couldn't use it for the time being, so it wasn't something that had been seen.

Merlin on the other hand, after removing Raven's powers, couldn't bridge regular dimensions to his inner world, and could only use it passively through his body. So only energy in his body could be sent and brought back.

"What good does that power have? If you can't store things inside, isn't it a waste to have an inner world?" Miles wasn't sure why Merlin was still so excited. If Merlin didn't want to keep Rayen's powers for the rest of his life, then he couldn't use the inner world actively. So, what good did that world have?

"You cannot visualize, because you have yet to reach Form-Rank. Once you do, you will understand how amazing this power can be, but let me explain it like this. Imagine my body as a tank of water. The water I can store in my body, the water tank, is limited, so after I fill it, I can only use that amount of water. Now imagine a second tank connected to my body that I can store and withdraw the water to/from." Merlin explained with a smug smile. At the end of the simile, Miles's mouth was agape.

"You mean, you can store the energy in your body to your inner world, and when needed, you can draw it back to your body and have at least double the amount of energy?" Miles asked with envy. He of course knew energy in the body was finite. One couldn't use it infinitely and had to be refilled. Thus, the bigger the reservoir, the more advantage the person would have. There was even a sub-branch mastering at storing more energy because their attack powers were inadequate. They would tire their enemy with endless small attacks, and when the enemy ran out of their powers, they would kill them.

Of course, only weak people would choose this branch. But now, Merlin with a cheat had a similar, nay, more powerful method. He could increase his energy reservoir at least twice, and when needed he could fight against several of his peers without getting tired. What kind of notion was that?

"That is exactly what I mean!" Merlin smiled and said "I didn't know it would be this strong. When I first heard Rayen powers, I thought I would have storage where I could hide my weapons and surprise my enemies, but now I can do more than that." Merlin was on cloud nine. Christmas came early for him and he received the best gift.

"How much energy can you store?" Miles asked with burning envy. How could he not be envious? He didn't even have any powers, while Merlin could copy any he wanted then he could even have these permanent passive abilities. Why is life so unfair!

"Not that much to be honest. Through initial tryouts I can say, I can only store 1/100 of my energy reservoir, but the ability should advance. I can feel that the walls of the inner world are expanding ever slowly." Merlin said and turned to look at the little girl hiding behind Miles. "How big is your inner world?"

"Um, I don't know," Rayen answered shyly.

"What do you mean you don't know," Merlin asked dumbfoundedly. "Do you mean you cannot say because you can't compare it to any item, or do you mean it is so big, you cannot comprehend its size?"

"I can't see the end of it," Rayen said after some time. Both Merlin and Miles looked at her with dumbstruck expressions. Especially Merlin who had just gained the ability and felt how important it was. If the inner world in Rayen's body was so big that she could not see the end of it with one look, it meant she could store so much energy, she would have an endless reservoir.

"It is not like what you think," Rayen said silently, more like muttering to herself, but both heard it.

"What do you mean?" Miles asked.

"It was as big as this when I first felt the world inside me." She said and brought her tender hands to her heart, "But the area I could control was as small as a sesame seed. That small area expanded ever so slowly and got bigger, but it doesn't mean I have full control over the rest of my inner world." She explained. Both Miles and Merlin asked the same question, at the same time.

"What is the part you can't control like?"
