Thanks to his magnetic field talent, he can drive the Storm of Blades directly with his core without any need to modify it. But he wanted to make it better, so he decided to modify it.
He wanted to make the Storm of Blades lighter, sharper, more durable, faster, easier to control, and more efficient at moving. For this, he created a core for it that would amplify the power of the effect of his magnetic field on the Storm of Blades.
This meant that the core will have the ability of his hammer to produce a magnetic field of its own and synchronize with the magnetic field of his core in order to amplify its power.
He designed the core to be like an ant queen. It will be immobile and will stay close to him.
The blades, on the other hand, will be the worker and soldier ants. They will be the moving parts that will be used to attack enemies.
In their idle state, the blades will revolve around the core. But once activated, the blades will smash into a target and strike them like a storm of blades.
This kind of update and modification required more work than what he did with the golden bow. But he didn't mind it at all.
He didn't even rush to complete the job. He took his sweet time making the designs, forging it, testing the artifact, and implementing the modifications that he came up with.
Even so, it took him less than two weeks to finish. So just a week before the exchange program, he had upgraded both the Golden Bow and the Storm of Blades.
The final product was a large, bulky violet bow and a black ball of blades.
The bow had become very large because he had to make the bow thick enough to contain the external golden core. This is why the bow is thick and nearly as tall as himself.
As for why it is violet, that's because it got influenced by his lightning energy and can also store a lot of it. The bow was also glowing faintly. The intensity of this violet glow indicated how much lightning it had stored for use.
On the other hand, the storm of blades is black like the hammer called Lightning's Descent. And just like the hammer, the storm of blades now has blue and purple runes.
Now he has four very powerful artifacts. One of them, Lightning's Descent, is for close combat fighting. The black Storm of Blades is for long-range fighting and can also form a makeshift shield to protect him.
Both of those two weapons function at their peak when they are either in his hands or within the range of his divine sense so that they will be able to receive enhancement from the magnetic field of his core.
Only the Violet Bow can create attacks at the limit of its peak power output without the enhancement of his magnetic field. This makes it very useful for ultra-long-range fighting with a range of attack that is far beyond his divine sense.
Lastly, he has the power-hungry formation breaker whose main purpose is auxiliary. The formation breaker's purpose is for breaking and creating formations. But it can offer advice on how to break the effects of spells, and it can point out the weaknesses of other artifacts and spells.
The four of them are very powerful artifacts. But they come with one main disadvantage, and that disadvantage is that he can't put them in space rings for long periods of time.
All four of them are technically alive because of the external golden core that he put in them. So he has to carry them along with him, or they will die in the space rings.
But this disadvantage is not a deal breaker. It is something he can live with and doesn't even notice most of the time because he can make them levitate around him.
The main problem is that people who see him will notice his weapons once they observe him. But aside from that, he is all set for the fourth mortal coil in terms of weapons. And it was just right in time for him to begin to prepare for the exchange program.
A notification was sent to him to inform him that the exchange program will take off in a few days. He was also given a list of people, their power level, and an overview of their fighting capabilities.
The people on the list are the disciples from the sect that he will take to the Purple Flower sect for the exchange program. His main job is to keep track of these people and protect them, so it is a good idea for him to know them well.
But the main reason he was given their information is so that they can properly utilize their fighting capabilities during the training of the exchange program. This way, he will be able to assign each person to the right job and show off the skills of the disciples of the sect to the greatest extent.
He memorized the information. Then he gave it to the formation breaker. He did this to broaden its knowledge base and improve its intelligence.
In order to maximize the utilization of this information, he gave the formation breaker a goal as a sort of quiz. The goal was for it to pair the people on the list with the priority to maximize cooperation.
He was essentially asking the formation breaker to determine those who will work well together. But he didn't make the task so easy.
He made the task more difficult by asking it to make groups with two people, three people, four people, etc., and to ensure that the people in each group will be able to cooperate well.
Each time, the formation breaker would have to change its answer and rearrange the people to create better groups. And each time, Arthur would grade its answers and point out its errors.
