Summoners War: Only I Summoned Divine Beasts

'Risa becoming a vampire progenitor?' Nathan was shocked. If he could really create a progenitor with his blood alone, it would change the balance of the world.

People would think they had to kidnap him and extract his blood to nurture a group of vampire progenitors. A lot more people would summon a vampire because there was a guarantee of success.

In fact, this could be a profitable business because he could sell his blood for enormous wealth. However, it would endanger his life.

He believed the vampire progenitor was standing toe-to-toe against the likes of the Fairy Queen and the draconian.

Announcing this to the world would simply bring those people out to hunt him.

On the other hand, this would definitely be useful for Selena. If Risa could actually become a progenitor, Selena would be the third summoner who had a vampire progenitor after her father and ancestor.

There was one problem. What about Lilith? Selena had been working hard because she wanted to summon a vampire progenitor. If Risa became a progenitor, wouldn't that goal vanish?

'No, wait. What if I let her summon Lilith but also increase Risa's power to the likes of a progenitor? This means Selena surpasses all the legends in her family and becomes the first person who has two vampire progenitors.'

Nathan could see what he was supposed to do once he returned to the academy.

Charlotte smiled and added, "I wonder if your blood can actually power up other familiars."

"!!!" Nathan's body shook. That was right. He didn't think about this. What about Sasha? Could her strength grow like Risa?

There was only one possible option. It was the Soul Contract. That was right. Was it possible to get or give Ena through the Soul Contract?

He had tested this with Fenrir and the others and assumed it wasn't possible. However, there was a chance it would work.

He just had to upgrade the Soul Contract one more time.

'I don't have enough understanding about the Soul Contract. I might be able to extort people through the contract, force them to sign, or even become a loan shark.'

Charlotte seemed to be satisfied with Nathan's response. She asked, "Do you have any more questions about your body? Although I want to give you a concrete answer about your body, you are simply too special, and I have to conduct some tests to understand you."

Nathan glanced at her. It was his original purpose coming here, but once he reached this place, he realized there was nothing that could resemble a library in this place.

That was why he asked, "Before that, can I tour around the library first? It's a shame if I'm unable to see anything after visiting this place."

"That is indeed true." She stood up and extended her hand. "In that case, I welcome you to my library."

After taking her hand, Nathan thought he would be transported again, but this time, she actually led her to the door, showing that this wasn't an illusion. She just made him think it was.

The moment she opened the door, there was nothing but a long corridor. He could see a few doors on the left side, but there was nothing on the right side. There was no lamp in the corridor. The only source of light was the small blue-colored ball that Charlotte summoned on top of her hand, making them unable to see anything beyond a few steps in front of them.

"I'm going back," said Nidhogg. "You can call me if you need me for anything."

Nathan nodded. Nidhogg was the laziest among them, so he just let Nidhogg back unless he needed him to fly or fight.

Fenrir and Anubis stayed on Nathan's side, not only because they were worried, but also due to their curiosity.

While walking down the corridor, Nathan couldn't help but ask, "By the way, what is the command type summoner? Can they enhance your ability?"

"You must be wondering about it after meeting that nun." Charlotte nodded in understanding. "That is indeed one of the abilities that most command type summoners use.

"It is called Synchronization. Let's talk about the chant for the summoning ritual. The chant is calling upon the miracle of this world, using your body as the beacon and granting a beloved passage, correct?

"Why do you need to mention 'beacon' in that chant? That is because every living thing's Ena has their own unique Ena. Of course, people from the same race usually have a similar type. That's why fire spirits can release flame, druids can control trees, and so on.

"Even though they are similar, they're not exactly the same. That's why the nun has to find your unique Ena and connect with it. After it's synchronized, she can then use her own Ena to boost your ability. You can do the same with familiars."

Instead of Nathan, Anubis was the first one to react. "Can a familiar use that ability?"

Charlotte and Nathan turned around, staring at Anubis. Nathan realized Anubis must have thought he wasn't that useful in battle because he only had three abilities: the strength enhancement, two bandages, and his Ankh of Immortality, which was his healing ability.

If he could just use his own Ena to boost Nathan, it would be perfect. However, he should have known this answer, considering Fenrir had proven he was able to copy Alisha's ability to a certain extent.

Charlotte nodded. "That is indeed possible."

"Is there a book for it?" Anubis asked. There was no way he could attend the summoner class, so it was better to learn it here.

"Yes. I can get the book for you." Charlotte assured him, knowing full well how hard it was to access things as a familiar.

After two minutes, they finally reached a giant double door.

"This is my library." Charlotte snapped her finger, as a cracking sound echoed above the ceiling as if it were controlled by a hidden mechanism.

Unlike the corridor, the entire library was actually lit up, which allowed him to see the entire library in one go.

He was on the second floor, so he could see all the thirty rows of shelves, along with the shelves positioned next to the wall.

The old paper smell filled up his lungs. Nathan couldn't help but ask, "How many books are there?"
