The steps to achieve Soul Divinity are to use the Knowledge Ring around the soul flame as the carrier of his willpower and laws before connecting with the soul Fusion. Ian has experience with Fusion, but he still needs to nourish his willpower and laws through trial and error.
So, he started with willpower first. The research on Haki greatly improved the development and understanding of willpower throughout the Empire, so the process was easier than expected. Ian completed Fusion after several repeated trials, and his soul fire Firehair changed.
Reaching level 9 requires a light golden flame, and in the previous breakthrough, his soul turned golden after absorbing enough energy from Soul Stone. Now, after Fusion gained willpower, the golden color has deepened, and is probably moving towards the level required to become Tier 11 - dark golden.
The next step in the process was to add a law, and Ian ran into a little trouble. He didn't meet the conditions for applying this universal law.
The thing about Luck is that he was well prepared for this and created a law weapon, which contained all the laws he could use, except for the soul and Mind Stone, because he only mastered these two laws in the Type-Moon universe and had not had time to create weapons for them.
He summoned these items from his personal dimension and began to combine them with his soul flame Fusion. He watched in amazement as his soul flame turned dark gold and then shifted towards a dark gold color. However, the process was halted as Soul Stone was unable to provide enough energy to complete it.
'That's a problem,' Ian thought to himself; he guessed that he could continue Soul Divinity now and upgrade later, but he would rather let the soul flame reach its limit before Fusion. However, the energy required for this process seemed not even Soul Stone could provide.
Ian's first reaction was to use the same spell that DC Universe had used against Darkseid. He summoned Soul Stone from different points in time, increasing their number to provide himself with more energy.
'This won't work because the Ancient One warned me not to use Time Magic. So, this plan may only work after she hands over Time Stone,' Ian concluded, then thought of his second plan: Duplication Charm
It was a wand spell that allowed him to copy items. Once he reached Tier 10, copying Soul Stone shouldn't be a problem. Although he deduced that these copies would not exist for more than thirty minutes, they would still provide him with plenty of energy.
'The best option is to connect this Soul Stone with all the corresponding gems in Multiverse. This will provide me with more than enough energy to complete the process, but I don't know this spell.'
Then, a thought suddenly flashed through his mind. 'Darkhold may contain such a spell.'
Darkhold was written by the first Demons Chthon, and that Demons was definitely an entity of Tier 11. Considering that the book would try to seduce the master by tapping into their deepest desires, it is likely that it would show Ian the spells he needs.
'This is an alternative plan, but don't rush to provoke this kind of entity yet,' Ian thought to himself. He temporarily stopped the transformation of Soul Divinity and focused on breaking through to Tier 10. A few days later, Ian's body met the requirements for entering the ninth level.
Then, before he could start, something unexpected happened. An unknown force from nowhere grabbed him and threw him backwards. He passed through a membrane, and the surrounding environment changed accordingly.
'What the hell?' Ian thought as he looked around. He was in a Dark Dimension with a red moon and a purple sky. The atmosphere was eerie and terrifying. After a few seconds, a creature walked in front of him. It was more than three meters tall, with horns, red skin, and a mouth so big that it grinned from its left ear to its right ear.
"Your soul is interesting; you should make a delicious meal." Ian couldn't understand the creature's language, but its meaning went straight to his mind, suggesting it was a soul or spirit communication.
"Huh? You can communicate with souls? I think this makes sense. This lord is the great Malakai, the soul eater. Today, you will have the honor to be my dinner."
'A dimension lord?' Ian thought to himself.
Malakai opened its big mouth and released an extremely terrifying devouring force. Ian's defense skills were activated instantly, but to no avail.
'Damn; he's at least Tier 10.'
Ian activated his Green Lantern Ring without hesitation, releasing a green energy shield to protect himself. He did the right thing - the shield blocked the devouring force.
"What an interesting magic weapon," Malakai commented. He raised his hand and shot out a powerful purple beam filled with the power of the fallen soul.
Ian used a highly concentrated willpower to fire a green beam to fight back. Their confrontation released a strong cosmic shock wave, but everything around them remained intact.
'He has absolute control over this dimension. I must leave as soon as possible,' Ian analyzed after observing the surroundings. Malakai hit the Snap, and millions of winged creatures appeared behind him. Ian retaliated in kind, creating a Empire Royal Navy fleet to annihilate these creatures.
He commanded the fleet to concentrate firepower on Malakai, buying himself enough time to use the ring to tear the dimension apart and escape. Malakai roared, and the entire dimension seemed to come alive, trying to prevent Ian from escaping.
However, he still used the small hole he tore to cast a spell and traveled to another dimension that he could perceive. He did not stop there; he jumped continuously for more than a dozen dimensions until he felt that no one was following him. Then, he finally returned to his previous position.
"What happened just now?"
He was confused. If it weren't for the ring, he might have been doomed. A strong sense of urgency came to his heart, so Ian moved the planet to another place. He added millions of barriers to block Void, and used Green Lantern Ring as an energy source.
Finally, he focused his attention on the task at hand. He converted the energy of Soul Stone into magic power and then absorbed it into his Magic Core and Soul Dimension's Super-solid Aether Core.
After reaching the 9th Galaxy Level, he felt that his body and soul had been sublimated; even his willpower had improved. However, this was not Ian's ultimate goal, and he continued his work.
He tempered his body and then absorbed enough energy to become the cosmic-level entity of Tier 10. This process is not simple, because galaxies are simply insignificant compared to the universe.
Therefore, before reaching Tier 10, he must first cross the levels of super galaxies, multiple galaxies and galaxy clusters. The thing about Luck is that Infinity Stones are all Tier 10 items with sufficient energy.
Ian felt the power rushing through his veins. Although this was not the first time he had controlled this level of magic, when it truly became his own power, the feeling was completely different from before.
Ian stared into the distance; the universe seemed so fragile to him at this time, as if his single thought could cause a terrible disaster. His spiritual thoughts instantly passed through every corner of the universe, and he saw every planet, star and galaxy clearly. His intuition told him that there were several places not to pry, and he listened to his intuition.
'As expected, there are too many terrifying existences hidden in this world,' Ian thought to himself. Although he had reached Tier 10, he knew that he was not the only entity that could affect the universe on this scale. However, other entities seemed to be very low-key, and he guessed what consequences might be brought about by taking action casually.
'No matter what, we have come this far, and this is the most important,' Ian thought to himself. Now, he must concentrate on moving to the next level: Tier 11.
"Boss, you look so handsome."
"Morgana? Are you awake?"
"I'm glad you're okay," Ian said with a smile. "I plan to use Malakai as a sparring partner to get used to my newfound strength. Let's chat while we fight."
"Okay."
