After entering the bathroom, he closed the door and sat in the bath while closing his eyes. Then, gently, he put his fingers on his temples and began to concentrate so he could enter his world.

In a blink, he found himself in front of the core of his world. The core remained the same half-meter tall crystal sphere with intricate lines all over its surfaces that didn't seem to have changed a lot, and it was shining with intensity, but not as much as when he created the first add-on. The only difference that Axel noticed was in the cultivation add-on that he created, which had changed again. The difference wasn’t big, but a few lines were thicker and a few more were added.

After looking at the core for a while, he noticed that there were a few balls made of light floating around it, which he thought should be his new add-ons.

He extended his left hand to grab one of the balls, and after doing that, it began to pull his hand toward the core, toward the cultivation add-on to be more specific.

Seeing that, he guessed that that ball should be the dantian sub that was reacting to the add-on that was compatible with it, so he made the rune and the ball touch themselves and they began to merge.

After a few seconds, he found that the ball had disappeared, and the rune was shining with great intensity while the lines were rearranging themselves and new ones were appearing.

It looked like it could take a little while until that procedure ended, so he did the same with the other balls. He fused the heaven's will add-on with the one that he created to stop time and the one that created the underground world with the main rune of the core.

This last one was the fastest and the one that made the least changes in the runes, maybe because the main rune of the core was much more complex and a sub of that rank couldn’t hope to modify it much.

After a few minutes, the shine stopped and the runes showed their new forms.

The time-stopping rune, which before had only a single curved line, suffered the biggest changes as it added tons of new functionalities, making it almost a new add-on with a truly complex rune, while the main rune of the core had one of its hundred of lines bent a bit.

On the other hand, the cultivation add-on changed a bit, but the difference that stood out more was that the rune looked like it was splitting in two, with a few lines that connected both sides.

"Well, maybe something will appear in the middle when it upgrades to the next rank", Axel thought.

After that, he resumed time so the changes could appear. He concentrated and changed the scenery in front of him so he could see the world from the sky, from where he spotted, in the middle of an immense ocean, the three islands that still had humans.

"Crossing such an ocean with primitive technology must be truly difficult. Buying the underground sub was a good decision", Axel said to himself.

A few seconds later, he felt how weak earthquakes were happening all around the world, probably provoked by the creation of the underground world.

Suddenly, Axel heard an androgynous robotic voice inside his head.

"Greetings, Master", said the voice in a monotonous tone. "I'm heaven's will autonomous operator. What are your guidelines for my work? "

"Oh, so you can talk," said Axel, surprised.

"Yes, I can talk. And if you dislike my current voice, I could change it for one that fits your demands", said the voice.

"Could you make it sound like a young woman's voice?", Axel asked.

"Like this?" said the voice, now sounding like a twenty years old woman.

"That's perfect. And do you have a name? "Axel continued asking, becoming more and more interested in the add-on.

"I don't have a name right now, Master is the one that should name me." The heavens' will operator responded.

"I will call you Heaven", Axel said. "From now on, you will be in charge of managing the world when I'm not around and will notify me if anything important or unusual happens. Also, if you see someone or something that could be a threat to the world, you have permission to throw some lightning at it."

"As you wish. I will create a heavenly tribulation to turn to dust anything that doesn't follow your guidelines. "Heaven said.

"Can you also control the other add-ons?" Axel asked while touching his chin.

"I can as long as you grant me permission." Heaven replied.

"Perfect, I permit you then. After the underground world is big enough, you will open a few entrances on islands where there are no humans, so flora and fauna will spread to the underworld. After that, you will expand it enough so the three islands that have humans become connected and they can meet each other. When they are connected, you will open their entrances and let them know that they should search for each other and begin a friendly relationship. Also, notify me when this happens. " Axel explained

"As you wish, Master", Heaven answered.

After that, Axel exited his world and returned to the bathroom. He decided to take advantage of where he was, and after finishing his business there, he returned to William's room.
