Summoners War: Only I Summoned Divine Beasts

"Aaaahhhh!"

Nathan had expected a more uncomfortable feeling than a proto-class since he had found the same thing when he absorbed the juvenile class.

Never in his wildest dream would he think of pain when absorbing a core.

His eyes were rolling back, leaving only the white behind. His body first arched up before it started writhing on the bed. He kept clutching his chest as the pain was concentrated in that part, as if the core was stuck on his trachea.

The pain was not ordinary. He managed to endure the excruciating pain from getting stabbed, yet Nathan actually screamed like never seen before. The pain must be unimaginable.

"Oi, stupid dog! What is happening here? What is going on? Heal him!" Fenrir panicked.

"I don't know. This must be a reaction to eating the core. There should be no problem." Anubis gritted his teeth. He was using his healing ability, but there was no effect.

"Then what are we going to do? The reaction has never been this severe."

They didn't know what was going on or what they were supposed to do. After all, Nathan's knowledge about summoning was limited, which reflected to them.

"Calm down for a second." Anubis observed Nathan and said, "From what I can see, he is only experiencing pain. And he is trying to maintain his consciousness. Since there is no injury, it means that the core is merging with him, but the problem is that... he has your strength enhancement."

"Is it relevant?"

"This is just a theory, but it seems that to swallow a higher class core, you need a sturdier body. He must have asked someone about it and gotten permission since he suddenly requested your strength."

"But it works, right? There's no way the soul contract doesn't work. You should know that."

"I know. But what if..." Anubis fell silent for a moment. "What if it was because it is artificial that he becomes like this?"

"!!!" Fenrir widened his eyes in shock. "Is he going to die?"

"I don't know. All we can do is observe him or find someone who knows about it. But if he has received permission, that means he's already qualified to absorb it, right?"

Fenrir frowned before coming to the same conclusion. "Then all we need to do is observe him?"

"Yeah."

The two gradually calmed down, even though it was uncomfortable to see him writhing in pain. They didn't mind laughing at him or teasing him, but they didn't want him to be hurt.

Nathan kept enduring the pain for more than an hour. The room had been soundproofed since the room was their private space to talk with their familiars within the academy. Then again, some students were going on a mission and some were not even in their room. The last few people that were currently inside their room either didn't hear it or didn't want to bother with it.

That was also why no one would help if Fenrir and Anubis refused to call for help.

After an hour, Nathan had stopped screaming even though he was still wriggling around. It took two whole hours before he finally stopped moving.

"Ha... Ha..." Nathan panted heavily. His throat was dry because he kept screaming. Even though Anubis kept healing him, he still needed water.

Fenrir also jumped to the bed, asking with a worried expression, "How do you feel right now? Is there anything wrong? Do you need anything?"

"One... minute..." Nathan answered weakly as Anubis grabbed a cup of water with his bandage and gave it to him.

Nathan didn't immediately grab it.

After a few minutes, Nathan gradually stood up, his body drenched in sweat. He grabbed the cup and drank like he hadn't drunk anything in the last few days.

"Ha... Ha... What is that?" Nathan didn't want to recall the pain at all. It was unimaginably painful. It felt like his body was being torn apart.

"Was it like Anubis said? Was it because of the artificial strength that you were like this?"

"I don't know. I should probably ask my teacher about it." Nathan shook his head helplessly. "I'm scared that I will have to get used to this kind of pain... won't I become an M at that time?"

Anubis and Fenrir didn't know what he was talking about.

"Anyway, I think that the pain I endure is nothing compared to the thing I gain." The pain had indeed subsided after an hour, but his head was ringing after that, giving him some weird understanding that he couldn't even explain.

"What did you get?" Fenrir asked.

Before answering to Fenrir, Nathan walked to the mirror and saw his status, finally understanding what happened.

Name: Nathan Reckmoon.

Level: 67

Race: Human

Quality: Good (Mid)

"As expected..." Nathan chuckled. "My quality has reached mid-tier."

"What?" Fenrir gasped. "How much Ena did the mutant core and the mature class core contained?"

"I don't know, but it should be a lot." Nathan took a deep breath. "What I get this time is my soul contract getting upgraded."

"Soul Contract is getting upgraded? What can you do?" Fenrir looked shocked.

"Soul Contract is a versatile and omnipotent ability if you look at it from a certain perspective. It allows you to establish a contract with us, or probably other humans, if it's possible." Anubis squinted his eyes, unable to imagine what kind of power he got from the upgrade.

Nathan smirked. "With this new contract, I can actually form a contract with an element in a certain area. For example, if I make a contract with a fire, I will be able to control that fire. If I make a contract with the wind, I'll control the wind in a certain area. There is range and limit, but it's actually pretty strong if you think about it."

"That is true, but what is the price?"

"The price is the same. It means I sacrifice the Ena for that area? Or maybe it's more accurate that I release the Ena back to nature?"

Anubis thought for a moment. "Doesn't that mean it's a double-edged sword?"

"Yes. If I sacrifice a huge amount of Ena, it might be extremely powerful. But I'll lose that Ena permanently. In other words, this is my trump card that can probably save my life in the future. I just wish I didn't need to use it. The loss of Ena is simply saddening."

Both Anubis and Fenrir knew that ability was extremely powerful, since he could contract an element. If they took another look, there was a chance that Nathan could contract an object like a desk or anything, which could become a weapon or something.

If Nathan kept progressing this way, the Soul Contract might become an extremely powerful ability.

And Nathan was the one possessing it. They knew Nathan could bring the best out of that ability... or at least, much better than them.

That was what made Anubis and Fenrir excited. What if Nathan had too much Ena to spare in the future? That contract might end up becoming permanent.

It seemed that there was still a lot to see from this summoner of theirs.
