Almighty Summoner System

Currently, Ban has a total of ten Cores, including the two Normal Grade E-Elite Rank Monster Cores he got from that Monsters of that two fellow who tried to rob him before.

Just like what Kuys said before, every Monster has their own Monster Cores regardless of Rank and Grade. The Summoner will need to strengthen this Monster Core for their Monsters to Rank Up. The methods range from letting the Monster eat beneficial foods for them all the way to using Methods that allow their Monsters to absorb Beast Cores. 

However, unlike Beast Cores, Monster Cores were naturally smaller. It might also be due to the fact that Monster Summons are smaller compared to Beasts of the same type with the same Rank and Grade.

And as such, the Monster Core that he got from the two Normal Grade E-Elite Rank Monsters were only the size of a fist, while the Normal Grade E-Elite Rank Beast Cores that he bought from the Blackmarket was about the size of two fists being combined.

At the moment, he has 2 Normal Grade E-Elite Rank Beast Cores, 4 Elite Grade F-Apprentice Beast Cores, 2 Normal Grade E-Elite Rank Monster Cores, 1 Elite Grade E-Elite Rank Beast Core that came from the Mild Tempered Crocodile and 1 Elite Grade Quasi D-Master Rank Beast Core that was rewarded by the System for its apology and as a reward for contracting the Unknown Egg. 

He handed the two Elite Grade F-Apprentice Rank Beast Cores to Eva and Tria and he settled for the Normal Grade E-Elite Rank Monster Core.

He then taught Tria how to cultivate the Beast Core with the method provided by the System. 

Eva already knew what to do so she naturally cultivated immediately not wasting any more time. At this moment, as a potential Lord Grade Beasts, her raw strength was on par with Ban who was already at E-Elite Rank even though she was still at the F-Apprentice Rank. 

Although it might seem good, she did not want to get behind Ban that much. She at least wanted to be stronger than him, so that she can deal with their enemy and so that she could protect Ban easily. 

Now that Ban already has the Core Manual, and with his abnormal absorption speed, she knows that their gap will only widen, if she doesn't work hard on her cultivation.

She transformed into her combat form to train it at the same time while cultivating. Although she could transform into her combat form for a long period of time, it was still inevitable that she would become tired the more time passed. Training it means extending the time before she feels tired while on her combat form. 

She then sat crossed leg and using four of her arms, she hugged the Elite Grade F-Apprentice Beast Core that Ban bought from the Blackmarket. She meditated and a while later, she entered the state of absorbing the Beast Core, to nourish and cultivate her own. 

On the other hand, Tria was clueless about what she was about to do next. She just hatched an hour ago and it could be said that she was still ignorant about the matters that were happening in her surroundings. 

Although her beastly instinct inherited from her ancestors was still there, she was bound to become confused about her situation. 

However, Ban was very patient as he taught and explained to her all of the things she needed. 

He also revealed to her his current situation and his sole reason for becoming stronger, but now have shifted to something else. Unlike before where his mind was only full of thoughts about revenge, it was now full of the desire to become stronger to protect himself, as well as his current loved ones, including his Summons, Kuys, Mario, the Kuys Bar, and more importantly, Emilia who had now become his girl.

The revenge was now secondary to him, but of course, he will still enact it when the time comes, it's just that he was no longer in a hurry just like before. 

After almost twenty minutes, he was finally finished telling her all the things she should know. 

The dragonfly girl no longer questioned anything as she flapped her wings with extreme speed before perching at the top of the Beast Core that Ban had given to her. Her two round and big eyes then dimmed, as she also started cultivating under the watchful eyes of Ban. 

Seeing his two hardworking Beasts, Ban also did not linger any longer and decided to cultivate along with them. He could not lose to them in terms of hard work can he? He was not talented after all. 

Ban clasped the fist size Elite Rank Monster Core and started chanting the Core Manual. Not long later, he immediately entered that imaginary place as he saw the blob of light that was smaller compared to the first time he entered this imaginary space. 

It was only natural, as the blob of light in front of him now was the essence contained inside the Monster Core or the Beast Core that he wanted to absorb. The amount of 'blob of light' corresponds to the essence left inside the Beast or Monster Core that he was about to absorb. 

He was trying to absorb the fist size Monster Core so it was only natural that it was smaller compared to the previous one. 

Anyways, Ban no longer wasted any more time as he reached out his hand to pluck those strands of the blob of light, before stuffing them directly to his mouth. 

At the same time, the silhouette of a man and woman appeared at his back yet again. Their silhouette was now blacker, or more precisely, their silhouette has now become more solid than before. 

They observed Ban with interest and joy as he kept on absorbing the Monster Core at a speed visible to the naked eye.

After one and a half hours, there was a 'kacha' sound as the Elite Rank Monster Core shattered into pieces. All of its essence was emptied by Ban in a matter of one hour and a half, a speed in which the woman silhouette thought as something freaky and absurd.
