"Is he from that group? Then it makes sense that he won the tournament." William said after hearing the teenager.

"Yeah, as far as I know, each of the four finalists was part of one of the three big groups," Adam said. "Sadly, the one that won against me lost against that guy. I can't even say I lost because I fought against the winner."

The "Black Demons of the Dark Seventh Hell," along with the "Salary Fighters" and "The Weapons of the Gods," were the most powerful groups in Axel's city, controlling almost every low-ranking rift that appeared on it.

Keeping that in mind, it made sense if that teenager had received large amounts of resources, making his world stronger than most of the other participants.

"What do we do now? Is there anything else that could be interesting?" Axel asked.

"There are a few talks about worldbuilding, but they are oriented toward coping worlds from works of fiction or games using worlds. There is not even one about competitive worldbuilding, so I'm not interested in any." William said.

"Me neither," Adam said.

"I guess we can leave already then. I have seen enough to understand that I'm not going to get anything else from here." Axel said while laughing.

After saying that, the three friends left the convention's fairgrounds and went to the nearest bar to drink something while talking. After a few hours, they parted and went to their houses.

When he arrived at his home, Axel went directly to his bedroom. There, he began to write on his PC the information about the next add-on that he wanted, so that when he had enough energy to create it, he would not waste even a second.

More or less half an hour later, he heard Heaven's voice in his mind.

"Master, the core has enough energy to create the next add-on."

After hearing that, Axel couldn't help but smile.

Without losing even a second, he left his room and went directly to the bathroom. There, he pulled down his pants and sat in the bath before closing his eyes to concentrate.

The image of his world's core appeared in front of him in no time. He stood still for a few seconds while looking at the empty slot while he remembered what he had written before he started speaking.

"From now on, certain symbols created with energy will work as runes." He said as energy began to accumulate in the slot to draw lines." Each one of those runes will have its own function and characteristics, and while they could be used alone, they will only reveal their true power when used multiple at once, as runes will be able to chain with each other to create bigger and more powerful effects. Also, each rune's effect may differ depending on which type of energy is used to fuel it at each moment"

After those words, a small rune had already appeared in the slot.

"While magical beasts may naturally develop runes on their bodies that they will be able to use to create multiple effects, humans will be able to draw them inside their seas of consciousness to manifest their effects on the outside. That way, they will be able to create more complex and powerful spells than by controlling the energy directly with their minds." Axel said as some lines appeared connecting the new rune to the cultivation rune.

"Besides all this, the Guburg tattoos from now on will be composed of runes, and they will be able to use the runes from different tattoos at once to fuse their effects and create new techniques or attacks. And that should be all for now." Axel finished describing the new add-on.

Finally, the new rune was complete.

Axel stood still, looking at it for a few seconds before a silly smile appeared on his face.

"I have just created a rune to make runes," he said, unable to stop the laughter from escaping.

After more time than he would like to admit, he stopped laughing and changed the view in front of him to see his world.

'Well, it is time to work. We need to get the runes discovered by the cultivators.' he thought.

"Heaven, show me the information of every Esvert cultivator with a mind above stage three but below stage seven. I think it is time to nurture new talent." He said as he looked over his world.
