You must first learn related magic and unlock the passive skills next to it by leveling up.
For example, to master Fire Element Mastery, you must master at least two level-two fire attribute magic spells to unlock this branch.
In other words, if you want to master those passive skills, such as elemental mastery, you must spend extra skill points to level up and learn related skills.
For ordinary people, skill points are naturally very scarce items. It's better to save them if you can.
But Roa is different. With his overflowing skill points, he doesn't have this concern at all.
Roa's goal is simple: after learning the skills he wants, he will forget the related skills in front to free up skill slots, and then repeat this process.
This is Roa's current plan.
As a result, after a day, Roa successfully filled his skill slots again.
All of them are passive skills, and the Crimson Demons are indeed quite strong. In terms of magic, they have experts in various fields.
Although they are a bit neurotic when they speak and their names are strange, they are indeed excellent in magic.
This can be considered an indirect boost to Roa's combat power.
The remaining time is for waiting. Soon, it was the next morning.
Roa, as usual, went to the tribe leader's place, only to find that a group of Crimson Demons had appeared around him at some point.
They were all crowded together with shining eyes, forming a circle.
Roa curiously squeezed in and found a staff placed in the center.
It was a staff about two feet long, with the staff body made of seven colors of dragon scales and the handle made of dragon claws and a dragon head. Lifting it gently seemed to feel the majesty of a dragon. When held in the hand, a profound water magic emanated from it.
Undoubtedly, the tribe leader had also spent a lot of money, taking out parts from the dragon's body for use.
Dragons can definitely be described as powerful in this world. The dragon's body is full of treasures, whether it's dragon scales or anything else, it can be used as refining materials.
However, Roa's expression was a bit strange.
The village chief saw Roa's arrival and quickly greeted him. He had a happy smile on his face, pointed to the somewhat flashy staff, and began to explain: "The holder can use it to release various water magic spells, creating various unpredictable water curtains and waves, and can freely control the shape of the water curtain to restrain enemies and protect themselves. In addition, the holder can use the Seven-Colored Nether Dragon Staff to summon a giant tornado, with the eye of the storm descending violently. Anyone who comes into contact with this tornado will suffer great damage."
Hearing this, Roa frowned and looked a little unhappy.
Ordinary stuff.
This was Roa's first thought.
He can release the so-called tornado whenever he wants, without so much trouble.
As for the control and protection effects attached to the staff, they are useless to Roa.
Indeed, ordinary mages are extremely afraid of warriors or assassins rushing at them, after all, most mages are short-legged and fragile.
But Roa is different. If the enemy dares to rush at him, Roa will let them see what true cruelty is.
In other words, the two effects that come with the staff are completely useless to him.
Thinking of this, Roa couldn't help but shake his head, feeling that this staff would most likely be sent to Roxy.
For strong people like him, few people use such things as staffs.
After all, staffs are strictly speaking auxiliary props, which can better guide magic power and provide a certain degree of blessing to the release of magic.
But the so-called blessing has a limit. Powerful magic cannot be withstood by the staff, and the magic power that can be enhanced is also limited.
Roa sighed, took the staff, looked at the tribe leader, and asked, "What's the name of this staff?"
But as soon as he finished speaking, Roa regretted it a little.
He just remembered the terrible naming ability of these guys.
And the next moment, the village chief said with a smile: "It's called the Seven-Colored Nether Dragon Staff, it's my most proud work."
Seven-Colored Nether Dragon Staff?
Roa's face became strange. He looked at the different colored scales on the staff, and the corners of Roa's mouth twitched.
It was indeed seven colors, but it always felt a little weird.
And the surrounding villagers, upon hearing the village chief's words, immediately set off a wave.
"So handsome!"
"As expected of the tribe leader, he came up with such an overbearing name at once!"
Similar praises rose one after another. Roa looked over and found that these chuunibyou were excitedly shining.
Roa said speechlessly: "Oh, it's called the Nether Dragon Staff? It's indeed a good name."
The tribe leader quickly shook his head and said, "No, it's the Seven-Colored Nether Dragon Staff."
Roa ignored the village chief and nodded to himself: "Thank you, tribe leader, thank you for your help. I'll leave first, see you again if we have the chance."
The tribe leader reluctantly nodded and said, "Okay, the thing is given to you, and our transaction is considered over."
Roa nodded slightly and said, "Then I'm leaving."
After speaking, he quickly found a position and ran away directly.
The reason is simple, the number of Crimson Demons surrounding him seemed to be increasing.
Most of these guys are sick in the head.
Roa couldn't imagine what would happen if he was surrounded by these guys.
The most urgent thing at the moment is to quickly take the things and run away.
…
After leaving the town, Roa finally had time to open the system panel to observe the attributes of the item in front of him.
[Nether Dragon Staff]
[Quality: B-]
[Trait 1: Dragon King]
[Increases the power of various magic spells, with the maximum power not exceeding the Emperor level.]
[Elemental affinity is greatly enhanced, and all released magic spells are reduced by 20%.]
[Can consume magic power to control the magic contained in the staff.]
[Intimidation, can cause a deterrent effect on enemies around with intelligence attributes lower than your own. The deterrent effect is calculated based on the intelligence gap between the two sides.]
There is only one trait, but there are four attributes.
How should I put it, it's not bad, it's a very good prop for a mage.
But the problem is, Roa is not a pure mage, and the spells entrusted in the magic wand are completely useless to Roa.
Secondly, his elemental affinity has been pulled too high, and the elemental affinity of the Nether Dragon Staff can no longer act on Roa.
This staff is of no use to Roa.
Roa shook his head. At first, he had high hopes for this staff, but he didn't expect it to play a joke on him.
Stroking the staff, Roa put the staff into the elf's pocket. He should find a chance to give this thing to Roxy.
Roxy should like it very much.
Well, let's give her a surprise, it's not like it's completely useless.
Opening the system panel, Roa chose to return.
[Konosuba: God's Blessing on This Wonderful World has been cleared!]
[You have successfully killed the Demon King Kyouichi Yasaka and obtained 500 points of Chronos Force.]
[You have successfully killed the Demon King Army Executive Yasaka and obtained 200 points of Chronos Force.]
[You have successfully killed the Demon King Army Executive Dullahan Beldia and obtained 100 points of Chronos Force.]
[You have successfully killed the Demon King Army Executive Deadly Poison Slime Hans and obtained 50 points of Chronos Force.]
[You have greatly changed the plot direction, you have obtained 500 points of Chronos Force.]
[You have greatly changed the plot direction, you will receive an additional 50% of Chronos Force.]
[You have obtained a total of three thousand points of Chronos Force.]
[You have obtained two S-level permissions.]
Lines of text appeared in front of him, and Roa's tense spirit finally relaxed.
It's not bad, he has gained three thousand points of Chronos Force and two S-level permissions.
Chronos Force doesn't need to be said much, it is the currency necessary to travel through various worlds. Permissions are the currency to bring characters from various worlds into the real world.
Gaining two S-level permissions at once is indeed quite good.
There is definitely no problem bringing Iris back. Although Iris's combat power is very strong, and the role she plays in the play is quite important, strictly speaking, she does not belong to the main character group, and the plot permissions consumed will not be too exaggerated. Consuming an S-level permission should be more than enough.
Then the remaining S-level permission can be used to bring Asuna over.
In the past, Asuna's matter has been put on hold because of this or that reason. Now it's different, there is finally time to deal with this matter, and there are enough plot permissions. Then what Roa needs to do is to go to that world to take a look, and then bring the girl back.
Before, the time ratio was adjusted to a very exaggerated level, but it is not a good thing to leave it alone.
After all, she is your woman, don't let others cuckold you.
After thinking everything through, Roa chose to return to the world of "Mushoku Tensei" and then choose to travel to the world of "Sword Art Online."
The time flow between the two worlds is different. To avoid confusion, Roa's choice is undoubtedly the most stable approach.
With a slight movement of his finger, he tapped on the system panel in his sight, and the next moment, a sense of dizziness came over him.
However, Roa was already used to it. This was a very traditional feeling of weightlessness, mainly because he had gotten used to it.
The first time he traveled to a new world, the feeling of weightlessness was the strongest.
But after that, whether returning or going to that world again, there would not be the same strong sense of dizziness as the first time.
After opening his eyes again, Roa was already standing under the crooked-neck tree in front of him.
The time before and after was not long. Roa went there purely to deal with a small matter, plus the original time flow rate, so naturally it wouldn't be too fast.
Roa moved his body slightly, and according to the memory in his mind, he looked towards the world of "Sword Art Online."
He did not immediately enter that world, but was constantly pondering.
Asuna naturally had to be brought over, after all, she was his girlfriend.
That society is a modern society, and it is also the only modern society Roa has traveled to among so many worlds.
The most famous thing in the "Sword Art Online" world should be the so-called game, and the Soul Architect in the later stages of the game.
In fact, sometimes Roa also wonders what the human soul really is.
Is it that as long as you retain your previous memories, that is, the so-called data, and this data is transferred to another person, then the so-called reincarnation is formed?
All the memories and experiences in the mind, combined together, form something called "soul."
If this "soul" is copied into two copies, will a brand new Roa be born?
And that world will have such technology in the later stages.
Roa is not very good at thinking about such questions. This kind of thinking is just thinking, and he doesn't dare to really put it into practice, because no one knows what the effect of doing so will be.
There were many thoughts in his mind. Finally, after thinking about it, he opened that world and prepared to go in and take a look.
The "Sword Art Online" world is a one-star small world, and it was the world Roa first traveled to.
At that time, he used a clone to travel. It was the first time to go to that world with his current body.
He opened the system panel, adjusted the time ratio, and prepared to enter that time again.
His finger clicked on the confirm button, and the next moment, when Roa opened his eyes, he found himself sitting in a chair.
The chair was a black gaming chair, which was very comfortable to sit on.
The young man opened his eyes, and a strange color flashed in his golden eyes.
With his long golden hair tied behind him, Roa got up from the chair and touched his cheeks.
It was his own face, no problem, but it was a bit strange.
In fact, Roa had been thinking before whether he would appear as Naoki Kirigaya or as his original self when he traveled over.
But now it seems that he is still himself, without any changes.
Scratching his head, Roa was still a little unclear about the system's handling methods, and while wondering secretly, there was a knock on the door.
"Hey, big brother, are you in the room?"
This voice was Kazuto Kirigaya's voice.
Roa rubbed his eyebrows and casually replied, "I'm here, come in."
The door opened, and a black-haired teenager walked in, holding a plate of cut fruit in his hand. The fifteen or sixteen-year-old teenager looked at the young man in front of him, hesitated for a moment, and then said, "Big brother, you can't keep shutting yourself in, you should at least go out for a walk."
Roa was stunned, estimated the time, and then asked strangely, "How long has it been since that incident?"
That incident refers to Roa clearing the SAO world.
In theory, he and the final boss, Kayaba Akihiko, had a final battle, and the two died together.
But it seems that it is not like that.
This body, that is, "Naoki Kirigaya," did not die, but came out to move around like other normal players.
