As for the Ninth-Tier Magic, Roa first considered death-type magic.
Roa does not lack powerful magic, but he lacks magic that involves similar death laws.
Roa had been coveting Old Bone's instant death magic for a long time, and if he had the opportunity, he would definitely want to get it.
These days, Roa has been considering what kind of skills he should get, and by the way, improve his reputation.
Some time ago, the fact that Roa killed the Skeletal Dragon in the cemetery was still found out by others.
Roa did not deny this matter, and admitted it very readily, and reported his findings to the president of the Adventurers' Guild in detail.
The president of the guild was greatly surprised and used almost all his power to investigate whether what Roa said was true.
The necromancer was indeed well hidden, but as long as this kind of necromantic transformation is carried out, there will be some traces. These traces are usually difficult to detect if no one pays attention to them.
But as long as you investigate carefully, there will always be flaws.
After investigating to the end, it was found that this matter was actually true, and the president of the Adventurers' Guild was shocked by this matter, and then his attitude towards Roa underwent earth-shaking changes.
Originally it was respect, but now the attitude can even be described as a bit flattering.
Roa spent these three days dealing with and consolidating his reputation, and also successfully obtained the guild's promise to upgrade Roa's adventurer level from Mithril to Orichalcum.
Roa's strength is beyond doubt. He killed two Skeletal Dragons alone. This strength speaks for itself and is enough to be worthy of this title.
If it weren't for the fact that Roa leveled up too quickly, otherwise, just solving this big crisis would be enough to advance from Mithril to the highest rank, Adamantite.
But this is just a small place after all. It has taken a lot of effort to promote Roa from Mithril to Orichalcum. Roa did not expect to directly become the strongest adventurer in this world in one breath.
Time went by, and soon it was three days later.
That night, Roa received a [Message] from Ainz.
"The things are ready, come and get them."
Roa had been preparing for a long time. The young man did not wear the green shirt, but changed his clothes. At this moment, the boy was dressed in white, white as snow. The young man had sword-like eyebrows and bright eyes, and his eyes revealed a heroic spirit, giving people an unquestionable sense of oppression.
This was Roa's special intention.
Roa made some slight adjustments to his original appearance, and the result was this look.
It's true that he only made some slight adjustments, but it gives people a sense of heroism. Coupled with this white robe, he looks like the protagonist in the Xianxia novels that Roa watched in his previous life.
Roa used Greater Teleportation, and his figure flickered a few times, crossing an entire prairie and arriving at his destination.
He released his magic power to sense it slightly, and he knew Ainz's location.
Of course, Ainz did not go alone.
He was also accompanied by three guardians who looked quite powerful. Not only that, there were also many heteromorphic beings hiding in the dark with stealth skills.
When the two met, Roa saw a huge treasure chest placed next to Ainz.
There is no doubt that what Roa wanted was in that box.
Ainz was stunned when he saw Roa's dress.
Because Roa's dress was a dress he had never seen before.
It does not belong to this world, nor does it belong to the Central European style, giving people a very wonderful feeling.
It always feels a bit like the style of a mysterious eastern country.
But it's true that the young man's temperament and appearance look very cool, and it's no exaggeration to say that he is handsome.
Of course, now is not the time to think about these things.
"Everything you wanted is inside," Ainz said first, pointing to the box next to him to show his sincerity.
Roa nodded slightly, but joked, "It's just a trade, is it necessary to be so cautious? You've used up half of your family's savings this time, haven't you?"
Roa's gaze turned to the three guardians behind Ainz, with a hint of curiosity in his eyes.
As mentioned before, the guardians are all at the highest level of 100. Of course, there are differences in strength between level 100 individuals, which depend on their specific class and equipment. However, reaching level 100 means their strength won't be too bad.
Yet this time, he directly mobilized three guardians, with a group of alien armies lurking in the dark.
In response to Roa's words, Ainz replied in a matter-of-course tone, "When facing unknown powerful enemies, no amount of caution is too much."
"That's true."
Seeing that Roa hadn't made a move and was still looking at his subordinates, Ainz couldn't help but urge, "Check if there's anything wrong with what you wanted. If not, then this trade is considered successful."
Ainz reached out and opened the treasure chest, revealing its contents.
There were various props and miscellaneous items, including the sealing crystals Roa had mentioned.
Many items were new to Roa. Ainz, fearing Roa wouldn't understand their value, explained, "These are all magical items. As you requested, I've exchanged them all for items that can seal magic."
"Of course, it's impossible to give you all sealing crystals. Even we don't have many. There are seven sealing crystals inside, capable of sealing any magic from the first to the tenth tier, as one-time-use items."
"I've used magic scrolls and other items to offset the remaining price difference. Is that okay?"
Roa pondered for a moment, estimating that the price was indeed about right, and nodded slightly in agreement.
"Then next is super-tier magic."
Ainz reached into his robes again and tossed out a piece of parchment.
He said expressionlessly, "It contains the super-tier magic I've mastered. You can see which one you want to learn."
Roa opened it and browsed. Ainz naturally didn't have many super-tier spells, and he was hiding the truly valuable ones, not showing them to Roa at all.
For example, he didn't even mention "The Goal of All Life is Death," a strengthened instant-death magic that could ignore the opponent's instant-death immunity and force instant death.
But even so, super-tier magic was still super-tier magic, and each had its own value.
As expected, Ainz's list only had four super-tier spells, exactly the four Roa had predicted.
First was [Fallen Down], followed by [Pantheon] and [Iä Shub-Niggurath], and finally [Wish Upon a Star].
In fact, Ainz had never cast Wish Upon a Star before. He didn't know that after the game became reality, this super-tier magic had undergone earth-shattering changes, and its skill effect had far surpassed other similar super-tier magic.
In Ainz's mind, this type of magic, like the previous three, was rare but not indispensable.
Moreover, Wish Upon a Star had a very serious drawback: it required consuming experience as a price to gain special buffs.
Was experience important? Of course, it was extremely important.
For a player, what could be more important than experience?
This loss was permanent, while the gain was temporary, so Ainz didn't think this skill was strong.
Ainz even thought Roa wouldn't choose this skill.
The parchment naturally didn't just list the names of these super-tier spells; it also described their effects in detail.
Although Roa had expected it, he still read it for a while, a slightly conflicted expression on his face.
Seeing Roa like this, Ainz couldn't help but find it amusing.
But then he thought, even a high-level magic caster like himself only knew a few super-tier spells. Although the other party was strong, they couldn't compare to him in terms of the magic they knew, so it was only natural for them to look like this.
Roa pretended to hesitate for a moment, then finally said to Ainz, "I choose this one."
The direction he pointed was the super-tier magic Wish Upon a Star.
A strange expression quickly appeared on Ainz's face. He reminded him, "Are you sure it's this skill?"
"Yes."
Roa nodded, and Ainz didn't say anything more.
Next, Roa asked for several high-tier spells.
First was [Grasp Heart], a high-tier skill related to the domain of death, which Roa naturally couldn't let go of.
In fact, Ainz was surprised when he learned that Roa wanted to learn this skill.
But despite his surprise, he didn't refuse since Roa wanted to learn it.
Ainz also had his own little plan in mind.
Don't think that [Grasp Heart] was a powerful weapon in Ainz's hands. It was unknown how effective it would be when used by Roa.
Roa wasn't a necromancer and didn't have any talent for instant-death magic. Even if he could cast [Grasp Heart], the effect might not be as good as he imagined.
After that, Roa chose several support skills.
[Anti-life Cocoon]
[All Appraisal Magic Item]
[Magic Ward: Holy]
[False data Life]
[Magic Caster's Blessing]
And a tenth-tier spell.
[Body of Effulgent Beryl]
These skills were all support-type skills, and their effects varied from person to person.
Roa wasn't a pure mage; he mostly used close combat, so skills that increased all attributes were quite useful to him.
Of course, besides these, Roa also learned the three spells he was most interested in.
They were the fifth-tier spell: Raise Dead
And the seventh-tier spell: Resurrection, and the ninth-tier spell: True Resurrection.
When it came to the domain of life and death, the more he learned, the better.
The topic of life and death was unavoidable in any world.
Some worlds had extremely strict control over the boundaries of life and death, while others had more blurred lines between life and death.
The world of Overlord was undoubtedly the more lenient type.
There were many ways to revive a person in this world, although the conditions were quite harsh, there were still methods.
The Thirteen Heroes who existed in this world could have been revived if they hadn't refused.
The three resurrection spells in Ainz's hands also had many limitations.
First was the lowest-level resurrection spell, Raise Dead
It had quite a few harsh conditions. First, the corpse had to be well-preserved, and the deceased couldn't have been dead for too long.
But even if all the above conditions were met, resurrecting the person by consuming a large amount of mana came at a huge cost.
In this world, it meant losing levels, about five or six levels.
However, this cost could be reduced by using higher-level resurrection spells. Of course, losing levels was unavoidable, and there might be various hidden small troubles.
So it was better to avoid dying if possible.
Of course, who could guarantee that their loved ones would always live safely and without any accidents?
So mastering resurrection magic was still quite important.
Thus, Roa continued to learn the magic taught by Ainz, and began to categorize these newly acquired spells.
There were few offensive spells among them, and they could be roughly divided into three categories.
First was the law category, involving the boundaries of life and death.
Second was the support category.
This category accounted for most of the trade. The characteristic of these skills was that they buffed oneself, increasing all attributes.
Finally, there was the offensive category, which was the smallest part of the trade.
Again, Roa didn't lack powerful offensive means. After all, a single flash of the Sword of Light had already brought his combat power to a nearly terrifying level.
Time slowly passed. By the time Roa had mastered all the magic on the trade list, the sky was already faintly bright.
The harvest was great, and it filled in some of Roa's remaining shortcomings.
Both parties expressed satisfaction with the trade.
But before parting, Roa suddenly made a request.
"You're planning to deal with Shalltear yourself, right?"
Ainz, who was about to leave, paused slightly. He turned his head to look at Roa, who had a smile on his face, and nodded slightly, "That's right."
Roa smiled brightly and said directly, "Then in that case, can you allow me to stand by and watch?"
This sentence was naturally directly rejected by Ainz.
"No." Ainz's expression was a bit gloomy. He looked directly at the white-robed youth in front of him and said, word by word, "I can't trust you."
