Wiz had all-white clothes, similar to a patient about to have surgery. Edward stood beside her, prepared to put a mask on her face. However, he saw the slight worry or fear in her eyes, so he stopped.

"Are you alright?"

"Just a little worried."

"If you want, we can postpone things."

"No, I'm ready."

He placed the mask on the side and held her hands: "Remember, I'm next to you. With me here, you don't have to worry about anything?"

Wiz held and caressed his surprisingly rough hands, and somehow, she felt reassured. "I trust you," she declared with a pure smile. Edward caressed her head before putting the mask on her face and laying her on the metal bed.

Then, a large glass tube covered her body before a green liquid filled the tube. Edward took his staff and used his Willpower to force the Universe Will to grant him access to [Death Authority].

Then, numerous runes appeared on the surface of the glass, and Edward's eyes glowed all white. He now could see Wiz's Soul inside her Soul Dimension.

"Morgana, inject the serum."

Then, a black liquid was injected into Wiz's body from the mask placed on her face. This was a serum made from the bodies of God and Satan from Black Clover. It would modify Wiz's Life Code to contain both the positive attribute of angels while also boosting her Lich body and the negative side.

So, for the next few minutes, he watched her shake incessantly during the transformation. Morgana monitored all her changes on an atomic level to ensure nothing went wrong. Once the conversion finished, he proceeded to the next step: the soul mutation.

Wiz's soul, who typically looked like herself in her dimension, began to change. She shone brightly in two colors: dark and gold. Edward monitored her carefully during the process.

Everything the dark spot overtook the gold one, he would use his staff to revert to the balance state and the same for the gold area. He would also ensure that the mutual transformation of the two lights did not damage her soul or the dimension.

The process lasted for a few hours before it ended. Then, the two lights fused with her soul's eyes, turning one side pure dark and the other pure gold.

'Success,' thought Edward with relief. Then, he checked the Soul Space, the connection of the soul and the body, the bloodline, and many other things to ensure no problem.

After not finding anything, he finally ended the surgery. He ordered Morgana to give Wiz plenty of healing potions for her health while gathering data on this procedure.

Then, he woke her up.

At first, Wiz was confused, but she quickly regained her bearing.

"How do you feel?" asked Edward.

"Different."

"Different good, or different bad?"

"I don't know," she replied as she looked at her hand. She then placed it on the metal surgical table she had previously laid.

"Purification."

A white light came from her, and the silver table instantly turned black.

"Is this the power of Arch Priestess? But why did it turn black?"

"The table is made of a magical ore. Your spell purified both the mana inside and the metal, essentially optimizing it." He walked to the table and easily removed a piece of it.

"Unfortunately, you purified it too much, so it's now a useless ore."

Wiz nodded before raising her hand to cast another spell.

[Undead Summoning]

A knight in dark gold armor appeared before her, holding his head in his hand. The knight immediately knelt to salute her.

"How fascinating. I have both the power of Lich and an Arch Priest."

After that, Wiz proceeded to test the limit of her power while Edward recorded everything. He even discovered that when it came to Purification Magic, she was as talented as Aqua.

After the successful transition, Wiz began her magical studies. In the past 10 years. The group only gave her some basic knowledge about the Empire and magic–in case things did not work out with Edward.

Now that she was officially one of them, she had much to learn. As for Edward, he had to focus on Lily's research. Using it, he created an Arcane Spark on his soul dimension that looked like a dark gold crystal floating at the center of the dimension.

"Let's test this thing out," he muttered before using the World Gate to teleport to a desolate Star System.

Sacred Spell: Star Explosion

Thousands of runes appeared around him, and from them manifested an enormous sun. Then, it exploded, destroying the entire star system with it. Luckily, Edward teleported away in time.

After all, although his attack reached Tier 8 Star System Level, he was still a Tier 7 Star Level and would not survive the explosion.

"The amount of my Karma used is not as big as I expected."

He then proceeded to use the same attack, but this time he used his negative Karma to cast a Sacred Spell.

"The destructive power of negative karma is at least 20% higher. I'm guessing there is also a bonus for healing spells when using positive karma."

Edward frowned as he could see the potential danger of the Arcane Spark. He did not doubt many people would not hesitate to commit heinous crimes to gather negative karma and increase their power.

This will be a significant problem since it only requires Tier 4 Country Level to cast an Arcane Spark. It did not mean that Arcanists could use Sacred spells as easily as they desired since their souls would not be able to bear power a whole Tier above them.

Most people will only be capable of using 1 to 2 Sacred Spells before tiring out. Nevertheless, he had to restrict the Arcane Spark to prevent a sudden increase in crime in the Empire.

"Then, there is also the issue of faith."

The Arcana Spark can convert faith into mana, allowing people to reach higher Tiers quickly. So, he did not doubt that many people would want to leave the Empire to conquer planets and other places, subjugate these people and force them to worship these Arcanists as Gods to increase their Tier.

As such, he decided to release two versions to the public. The first version only allowed people to use their karma for Sacred Spells. However, strict contacts will be signed to ensure these people will not actively commit crimes to increase their Karma.

The second version is the full version with the Faith Conversion Ability, but even stricter contracts will be required to get their hands on this method. Although Edward will not ban [Faith] in the Empire, they will be severely controlled.

After making some preparations, he left. There was nothing more left for him in this world, so it was time to return home. Before leaving, he plundered Heavens, Hell, the Gods, the Devils, and all the dimensions these places controlled and had access to–including Axel.

Subsequently, he plundered the population of Earth–including Kazuma and Megumin. Of course, he did not immediately leave. No, he traveled the multiverse to parallel dimensions where the population differed from the one he came from.

Then, he would plunder the entire population, as he did in his previous world. He did that numerous times until the Universe Will acted and exiled him from the universe.

So, Edward placed the Floating City inside the World Gate before heading home. The Floating City required a lot of time to upgrade to the new Void Core Engine, and he did not want to wait. Furthermore, he wanted to update it in one go instead of piece by piece.

The 3.0 Version should have the ability to fight against Tier 10 Universal Powerhouses.

"Morgana, how is it?"

"The calibration for the Void Core Engine is still off; we are one day travel away from home."

Edward was still satisfied since we cut a trip that would take a few months to one day. Twenty-four later, he could overlook his home world's Crystal Wall.
