The testing for magic beasts of the beast masters were only strength, speed, and reaction speed. As for the blood sample and the likes, it required Sophia's consent before they were allowed to take it.

Considering that Sophia was not the type of person who wanted to have her magic beasts' blood to be drawn, she refused. So, the test for the magic beasts were relatively simple.

"Why don't you want to analyze the magic beasts' DNA?" Ruby asked curiously.

"I don't want their information to spread out," Sophia replied helplessly.

"What if their blood are taken during a battle?"

"Then they need to have that ability."

Her magic beasts were not weak and Sophia will get a new magic beast after Riya went to pay another visit to the crack. It would be impossible for others to get a lot of information from her magic beasts unless they were stronger than them.

"Alright." Ruby didn't persuade Sophia either.

After all, this matter was related to the other party's privacy.

"By the way, I'm here to give you this." Riya handed over a necklace. "It's an upgrade version from the previous one and no one would be able to hurt you."

She couldn't protect her friends forever, but at the very least, she didn't want to see them got hurt. Since she had advanced to rank 7, making rank 7 magic formation would be quite easy and what Ruby needed was a full protection.

That kind of magic formation was easier to make than the one that would allow them to still attack their enemies.

"Thank you!" Ruby happily accept the necklace and took out a black ball around the size of her palm. "This is my latest invention, dark mana element storage. I know that you don't really need it, but I don't really have anything else to give you."

"You don't really have to, though," Riya said helplessly, but she still took the black ball. Because Riya had all elements in her body, she simply inputted the dark element mana into the black ball and her eyes flickered with surprise.

Items that could store mana was not exactly rare in that world, but none of them learned how to make them. After all, many of them had to go through rigorous process before the final product could be seen.

They all wanted to advance to rank 7 at the fastest speed possible, so how could they waste their time researching about these things?

Besides, most of them would need to use runes to strengthen it.

"The amount of mana you can store inside is not much. I ask Ruben for help testing it before because he's the only dark element mage that I know," Ruby explained calmly. "He said that it can only store to the limit of a rank 1 mage's mana, which is still quite a lot for magic warriors."

Ruby herself didn't really slack off in her training, but she was definitely far behind her other friends. After all, she didn't have much passion to train or anything like that.

Even when they were in the university, Ruby hated sports class.

She felt that it was not necessary for her to push herself too hard because it was really tiring and all.

It's better to make more things and do research.

This black ball was the best invention that she had made so far and Ruby was very proud of it.

Riya nodded with a smile. "It's not bad. Do you have another one?"

"Yeah, I made a lot of samples," Ruby replied and took out another one. If Riya wanted it, she would give it to the other party as much as she wanted. The main materials to make it was the dark creature corpses that Riya had given to her.

Without Riya's support, there was no way she would be able to make something like this.

Riya only took one and then started to draw runes with her other hand on the second black ball. Her fingers moved quickly and soon, beautiful engravings were visible on the surface of the black ball in silver color.

This made the originally dull ball looked beautiful.

"This…"

"I increased the capacity and made it more stable. Most magic tools are usually accompanied by the supporting runes to increase their performance," Riya explained calmly and handed the second ball back to Ruby.

"Based on the materials and limit, I can only increase it around 100 times the original capacity. In other words… it should be at the limit of rank 3 magician's mana?"

Since Riya was not exactly participating in the research, she didn't have clear value about the amount of mana she has. After all, it was not that easy to calculate the amount of mana that a magician and magic warriors has.

"Wow." Ruby was astonished and her hand trembled a bit as she held the magic ball in her hand. "Can I… Can I use this for the press conference?"

"Sure. I'll let give you the drawings later." Riya nodded and thought about giving the runes drawing to Ruby later. It was not that complicated and this was considered a rank 3 magic formation.

Considering the level of the rune masters all over the world… no one but Riya would be able to make it.

Hmm, should she make the lesser one?

Ruben could already make rank 2 runes and formation so those rune masters from the government's side shouldn't be lagging far behind.

Since Riya didn't have any plan on going to the capital city, she could only use Ruben's speed of improvement to gauge their speed.

Ruben: "…" so I have become an unit to calculate other's progress?

"Thank you!" Ruby was happy and wanted to go back and directly test the magic ball that Riya gave to her. If it was not because her friends were still here, she would have gone back without hesitation.

Amelia chuckled when she saw Ruby's expression. It was really rare to see Ruby so impatient like this.
