While Riya has enough contribution points, she wanted to exchange for some practical magic spells and try to see if she could make the specific formation or runes from these magic spells.

She didn't know the price of these magic spells, but she could guess that they were expensive.

Since Riya didn't specifically gather contribution points, she might not have enough to trade for what Ruben might need.

"It's fine, Master. I have enough contribution points." Ruben chuckled.

He had already checked those magic spells and their description. All he needed to do was to go back to City A Base and traded for them.

"Also, since you'll be using the special magic core, you might have to retrain your mana control again," Riya reminded.

She herself was fine because her own mana control had reached the level where she could even control the amount of mana that she took out from her body. It would not be difficult for her to bypass the ranks and so on.

But Ruben is different.

This was the first time he had reached rank 5 and the special magic core will definitely push him further.

After that, what awaited him might be the fact that he couldn't control his strength well.

"I understand." Ruben nodded.

Even though he would have to spend his time to train again, Ruben didn't care. Being able to get stronger faster was something that many people had dreamed in their entire life.

Riya still has more rank 5 special magic core and was thinking about what to do with it. After all, she couldn't give it to these people all the time. They were only following the simple paths that these returnees shared.

Compared to the returnees who have various means… their needs for mana was far lower than them.

Of course, if they were to make a good use of their talent, there was still a possibility for them to surpass the returnees after a long period of time. As for how long it is, Riya didn't know and didn't think that she should give them false hope.

'Hmm, need for mana?'

If Riya was not wrong, Ruben's element is dark element, which has practically saved his life when he did reckless things in the past.

Riya looked at Ruben and then smirked. "Ruben, do you want to have more mana compared to other people of the same rank?"

Ruben saw Riya's smile and suddenly had a bad feeling. "Uhm… is it possible?"

"Yes. I can engrave runes for you, but it'll be a bit painful," Riya replied.

"Is there any other advantage?"

"You can use more mana than people of the same ranks and the runes will make your element stronger but at the same time, you will really need to spend more time practicing your mana control because it'll be harder for you to control your mana," Riya replied honestly.

She had only remembered about this matter when she thought that Ruben has dark element.

The dark element was a relatively special element and there were not many people who knew about its special characteristic for rune master. Riya knew about it because she herself has dark element and her master mentioned it.

For dark element rune master, there was a special path that they could take.

When Riya remembered this, she felt that Ruben might be suitable.

Even if he didn't have any plan to truly reach the peak, this could help him to increase his strength at the fastest speed possible.

Uh, he will need more mana, though.

So his speed might slow down instead.

"Disadvantage?" Ruben asked again.

"Your training speed might slow down to a certain degree," Riya replied. "Because your need for mana in each stage will increase significantly."

Just like her, having to use a lot of special magic cores to increase her strength. But at the same time, she's also far stronger than those of the same ranks.

Right now, aside from the fact that she needed a lot of resources, she's definitely far stronger than many other people of the same ranks. It was also because all returnees have their own methods of getting stronger that they were able to deal with rank 7 magic beasts even before reaching rank 7 themselves.

The price was indeed tragic, but they were not completely helpless.

If they had followed the ordinary path… they would have never been able to reach that level.

"Then do it." Ruben grinned.

If this meant that he could get stronger than those of the same ranks, then he will take this risk.

He's not afraid for he believe that Riya would not hurt him.

Riya smiled and glanced at Samuel.

"Go to the room and I'll guard it," Samuel said calmly. He was curious about what Riya wanted to do, but he believed that she will not harm Ruben.

"Alright, let's go."

The two of them headed to the room and Samuel stood by the door. He could sense mana fluctuation from inside the room but he stayed there quietly and saw that Stephen had also finished.

"It seems that your mana control is the second best in the group," Samuel commented.

"I'm a magician, so it's natural that I'm better than magic warrior." Stephen shrugged and then he glanced at the door before looking at Samuel again.

"What is it?"

"Is there any way for me to get stronger faster?" Stephen asked.

After taking that rank 5 special magic core, he had already reached the peak of rank 4 and he felt that with a little tug, he will be able to reach rank 5.

But Stephen had the feeling that this rank was far from enough for him to deal with the Carson Family.

Those greedy b*stards would never feel enough unless they have enough strength. Besides, Stephen also knew that the Carson Family had reached some cooperation deal with the magic association.

If he couldn't get stronger faster, there might be some people who wanted to trample on top of them.
