Axel stood still for a few seconds as he thought about how to express his ideas.

'Let's start with the cultivation add-on. The changes should be smaller than creating a whole new add-on, and I need it to resume the time in the world, so I think it is the best choice.' Axel thought.

At first, he didn't know how to continue the cultivation path of his world, but after seeing how the snake broke thought during the fight against Adam, he decided to use the direction that the rune had developed by itself.

Of course, he wouldn't leave it to develop without his supervision. Instead, he would modify the rune to add those functions himself, so the add-on could end up being exactly as he wanted.

'Well, let's get started with some little changes to spice things up a bit.'

As he was about to speak, the core's energy began to accumulate on the cultivation add-on.

"Instead of nine stages, the first rank of cultivation would have ten stages, with the tenth being optional, as anyone that reaches the ninth stage would be able to attempt to breakthrough. The more a creature advances on the tenth stage, the easier the breakthrough to the next rank would be for that creature, while at the same time, it would be easier for it to advance to the next rank and would be stronger than those that broke through on the ninth rank." Axel said.

He had been reading a lot of cultivation stories lately, and if something happened in a lot of them, it was the fact that the MC always reached the highest stage possible, maximizing his powers and ending up being able to fight with enemies above his rank thanks to his strong foundation.

And according to what he knew about world building, adding those kinds of conditions would allow his add-on to be stronger while using more or less the same amount of energy, so in his opinion, that change was mandatory.

Next would come one of the most important changes in the cultivation add-on and the idea he got when he saw how the snake broke thought to the next rank.

"When a creature reaches the peak of the ninth rank, they will be able to summon a tribulation to test their might and skills. That tribulation would consist of lightning bolts that would fall from dark clouds onto the creature. Those lightning bolts would contain small amounts of heavenly-energy, which the creature that is passing through the tribulation would be able to absorb and transform into other types of energy. In absorbing that heavenly-energy, their dantians would transform and purify to match the type of energy that they had chosen, and in that way, they would enter the next rank."Axel said."When a creature reaches rank two, their goal would be to use their new, improved dantian to create purer energy and gradually adapt their bodies and minds to that energy, increasing their purity and power."

Having thought of all he wanted about the general breakthroughs, Axel began with the more specific cases.

"Besides that, the magical beast would also get a bloodline when they reach rank two if they didn't have one yet. These bloodlines would be like a blueprint for their descendants, as they would dictate the characteristics and powers they would get with each breakthrough. Each time a creature manages to surpass the stage or rank that its bloodline dictates, the bloodline inside them will advance to add those new upgrades that the creature could have suffered. Also, thanks to this, magical beasts with bloodlines would not need to pass the tribulation to enter rank two, as their ancestors had already demonstrated that they were worthy of that power, so their bloodlines would create pure energy by amassing large amounts of regular energy. And that should be all." Axel said with a smile.

After finishing saying all that, many lines appeared on the rune of the cultivation add-on as the energy fused with it.

But suddenly, something happened.

The add-on that was previously split in two began to fracture and expand towards the empty slot on the core.

"What is happening?" Axel asked, panicking.

"The add-on has too many functions for the current rank of the core, so it is splitting to be able to maintain itself," Heaven explained.

"Can you stop it?" Axel was concerned.

"I can, but it will require increasing the energy consumption of the add-on by a large margin," Heaven explained.

"Do it! I don't care if it consumes the double or even the triple, I can't lose that empty slot!"

Like that, the modifications to the cultivation add-on came to an end.
