If that were the case, then the opponent that Roa faced would directly smash his face with Super-Tier Magic.
But fortunately, it was obvious that this world would not allow such a thing to happen.
These two restrictions were the best proof.
But even so, this item was still extremely powerful. After all, it almost recorded all the Super-Tier Magic in this world, as well as the Origin Magic that players could not master. And as long as these magics were recorded on it, it meant that they could be released. And when facing enemies of different classes, this item was equivalent to giving the item owner all-round protection.
If Ainz mastered such an item, the so-called strike damage and fire damage would no longer be weaknesses. At least in battle, Ainz could ignore the so-called attribute restraint, and even use attribute restraint as bait to trick the opponent severely.
After all, with such an item, it was equivalent to mastering an additional Super-Tier Magic, which could be adjusted in a targeted manner.
"Okay, this World-Class Item is not bad." Roa finally gave his evaluation.
Zesshi Zetsumei was eating melons throughout the whole process. Seeing Roa's happy face, she couldn't help but ask curiously, "What is the use of this item?"
Roa took the Nameless Book of Spells and knocked it on Zesshi Zetsumei's head, and said casually, "The use? It's probably to be able to cast any magic in this world."
Zesshi Zetsumei's eyes lit up, and she blurted out, "Are there no class restrictions?"
Roa glanced at Zesshi Zetsumei and said a little unhappily, "There are magic power restrictions. Your small body can't handle it."
Zesshi Zetsumei then cut and felt a little disappointed.
Roa smiled slightly, reached out and held Zesshi Zetsumei's hand, and prepared to leave here directly.
Zesshi Zetsumei did not resist at all, and honestly let Roa hold her, with a little blush on her cheeks.
Roa didn't look at Zesshi Zetsumei. Roa glanced at the NPC who had fainted on the tenth floor, thought about it, took out the Depiction of Nature and Society, spread out his hand and grabbed from it, took out an item and threw it casually, throwing it in front of the NPC who had been knocked out by Roa. After doing all this, Roa took Zesshi Zetsumei and stepped into the teleportation gate, and their figures disappeared.
Roa returned to the kingdom as soon as possible. The kingdom did not have much change on the surface, but in fact, the upper levels were already changing silently.
With Roa's hint, Ainz had already prepared to attack the kingdom, to carry out a big purge, and by the way, directly seize most of the rights of the kingdom's nobles.
According to the covenant that Roa had made with the other party, Ainz's side could not do anything to bully the weak, or indirectly kill any innocent person.
This covenant was not simple. Signing this covenant was equivalent to being directly bound by Roa's mental power. Once the other party wanted to do anything that violated the content of the covenant, their heads would hurt as if they had been pricked by a needle.
Roa took Zesshi Zetsumei and walked around this Royal capital again. After confirming that everything was correct, he said to Zesshi Zetsumei, "It seems that the matter here has been dealt with. Next is Zesshi Zetsumei, your matter."
"My matter?"
Standing beside Roa, Zesshi Zetsumei, holding Roa's hand, tilted her head in confusion, her black and white pupils filled with bewilderment.
"Mm," Roa responded softly, his expression unchanged. He gently but firmly pulled Zesshi Zetsumei into his embrace, took a step forward, and in the next moment, an invisible spatial ripple spread out. When they reappeared, they were standing in a desolate wilderness.
Forests, trees, wastelands, bushes, and scattered piles of stones made up the entirety of the scene.
Roa looked at Zesshi Zetsumei and said seriously, "Since you're an inner disciple, I have to leave you with some means of survival."
"Create Greater Item."
Roa raised his right hand, his expression calm. The next instant, a black longsword appeared in his hand.
The longsword was about seventy percent similar to the Staff of Ainz Ooal Gown, looking more like a replica of it.
Roa looked at Zesshi Zetsumei and asked, "Your ability allows you to use the strongest techniques of the previous owners of a weapon, right?"
Zesshi Zetsumei nodded.
Roa continued, "Then let's see if you can perform my techniques. Of course, my techniques are sword skills, and performing them requires a lot of stamina and puts a significant burden on the body. I'll adjust them according to your limits first, okay?"
Zesshi Zetsumei finally understood and her eyes lit up with excitement. "Okay!"
Zesshi Zetsumei still couldn't forget the light that pierced the heavens, and that sword strike had left a deep impression on her.
If one hadn't witnessed the splendor of that sword strike, who could have imagined that someone in this world could wield such a sword?
Roa released Zesshi Zetsumei's left hand, smiling as he stroked her head. Zesshi Zetsumei blinked, her gaze fixed on Roa, who could feel the anticipation in her eyes.
"In that case, watch carefully."
Roa walked forward a few steps, found a suitable spot, and drew the longsword.
The black longsword gleamed with a dark luster, and in terms of appearance alone, it seemed quite impressive.
In reality, the quality of this weapon was indeed quite good. Although it couldn't compare to the Staff of Ainz Ooal Gown, it was far superior to most weapons in this world.
Roa gripped the hilt, swung it a few times, and felt the balance. Zesshi Zetsumei watched him intently from the side.
Roa had chosen a spot where Zesshi Zetsumei could see more clearly. He had no intention of being secretive and planned to teach her the Sword God Style properly.
Of course, how much of the Sword God Style Zesshi Zetsumei could master was beyond Roa's concern.
Frankly, Roa was just trying it out. Zesshi Zetsumei's real advantage was her ability to use the skills of a sword's previous owners, which was extremely beneficial for a swordsman's training.
For swordsmen, especially those at a very high level, it was common to be stuck at a certain bottleneck for a year and a half, or even decades.
But for Zesshi Zetsumei, she didn't need to worry so much.
She could use the sword techniques of others, stand on their shoulders, and see more of the scenery. This was a difference in realm. Walking the path paved by predecessors was naturally much better than finding a way out alone.
Of course, the task before Roa now was not to teach Zesshi Zetsumei how to use the Sword of Light, but to see if she could withstand it.
Roa held the sword horizontally at his waist, leaned forward, gripped the hilt firmly, and unleashed a sword strike.
The strike wasn't fast, and Zesshi Zetsumei could see it clearly. The movement was quite standard, but overall, there were no fancy effects or powerful attacks.
Roa met Zesshi Zetsumei's gaze and began to explain, "This is a sword move. This is roughly how I swing the sword. It's simple, right?"
Zesshi Zetsumei nodded.
Roa retracted the sword to his waist, exerted force with his right hand, and unleashed another strike. The strike cut through the air, carrying unparalleled force, splitting the air in two. Zesshi Zetsumei estimated that if there were a tree in front of Roa, this strike could instantly cut it in half.
It was an exaggerated amount of force, but for Roa and Zesshi Zetsumei, achieving this wasn't difficult.
This time, the speed of the strike had increased significantly, but it was still within Zesshi Zetsumei's perception range.
Roa explained again, "Slightly accelerated. You can do it too, right?"
Zesshi Zetsumei met Roa's gaze and nodded under the gaze of his pale golden eyes.
"Then, find that feeling and unleash the Sword of Silence!"
Roa took a deep breath, still in the familiar stance, leaning forward, right foot forward, but this time, the veins on his right hand, which gripped the hilt, bulged, and all the aura around him was restrained.
Zesshi Zetsumei tensed slightly, knowing that the main event was coming. She focused all her attention on Roa's every move.
The next moment, Roa struck.
This strike was silent. Zesshi Zetsumei didn't see any movement from Roa, but she realized that Roa had already unleashed that strike.
In her vision, it seemed that a sword had been swung out at an extremely fast speed.
"How was it?" Roa asked Zesshi Zetsumei, turning his head after completing the movement.
Zesshi Zetsumei's expression was serious. She opened her mouth, but in the end, she only said slowly, "Barely, I could see it."
Just as she said this, a tree three feet away from Roa was instantly cut in half.
The whistling sound of the air being torn apart rang out belatedly, and the strong wind forced Zesshi Zetsumei to squint.
Roa pondered, hesitated for a moment, and threw the weapon in his hand to Zesshi Zetsumei.
Zesshi Zetsumei caught the longsword, and Roa said to her, "Try it."
Zesshi Zetsumei gripped the longsword, walked to the spot where Roa had cut down the tree, took a deep breath, and concentrated her mind. She began to activate her talent.
Zesshi Zetsumei's talent also had a time limit. She needed to rest for a period of time before she could use the same technique again. The length of time depended on the strength of the ability attached to the weapon.
Holding the black longsword, Zesshi Zetsumei imitated Roa's posture, holding the sword horizontally at her waist. The posture had some slight differences, but it was roughly the same.
Zesshi Zetsumei was also a martial artist. Although she didn't have much practical experience, she had some skills and some knowledge of swordsmanship.
Of course, this knowledge was like an ant trying to shake a tree compared to a sword master like Roa, a dwarf looking up at a giant. The difference was too great to even compare.
To have someone who wasn't proficient in swordsmanship unleash the Sword of Silence, if this were in the Mushoku Tensei world, it would make the guys at the Holy Land of Swords laugh to death.
The Sword of Silence was actually the Sword of Light, but the speed hadn't reached the level of the Sword of Light. But it was undeniable that anyone who could unleash the Sword of Silence had reached the Sword King level.
Roa had originally thought that Zesshi Zetsumei might need to practice for a while, and the process would be very tortuous. In short, Roa didn't believe that Zesshi Zetsumei could unleash the Sword of Silence in one go.
However, when Zesshi Zetsumei actually used her talent ability, Roa was quite surprised.
The auras began to overlap, and Zesshi Zetsumei's movements began to subtly adjust, gradually becoming perfect.
The movements, breathing, and even the aura around her were almost a replica of Roa.
"Tsk, this is really surprising." Roa clicked his tongue in wonder at Zesshi Zetsumei's appearance.
At this moment, Zesshi Zetsumei had also entered a mysterious state. A strange emotion began to flow in her heterochromatic eyes. She felt a force surge from the longsword and pour into her body.
And in her mind, the scene of Roa swinging the sword earlier appeared.
It was a very wonderful feeling. She felt as if she had become that person, and an intuition was telling her how to swing the sword, with what force to swing the sword.
Zesshi Zetsumei's body began to move. She followed that feeling and unleashed this sword strike.
The sound of the air being torn apart rang out. The black longsword was extremely swift, unleashing this strike at an exaggerated speed.
Even Brain, who was known as a genius, would be ashamed of himself if he saw this strike. His secret technique was completely inadequate in front of this sword strike.
But even with such a sword strike, the expressions of the two people present weren't very satisfied.
"It seems it's still a bit inferior?" Roa stroked his chin and began to ponder.
This sword strike looked powerful and the attack was very fierce, but in reality, it was still a bit lacking.
Because it hadn't reached the realm of 'Silence', which meant that this strike hadn't exceeded the speed of sound.
Zesshi Zetsumei, who had unleashed this strike, waved her slightly sore arm, but her eyes sparkled with unusual excitement.
She said to Roa in a surprised tone, "Master, I felt it just now, the will that you conveyed at that moment."
Roa looked at Zesshi Zetsumei in confusion, somewhat puzzled.
Zesshi Zetsumei organized her words and slowly said, "I feel like, at that moment, I was like Master, I could do it!"
Zesshi Zetsumei's words were a bit confusing, but Roa understood what she meant.
Roa muttered to himself, "It seems she can replicate the sword techniques I unleashed at a certain moment?"
Roa wasn't too surprised by this result. Zesshi Zetsumei's talent was indeed abnormal to some extent.
