In the Mushoku Tensei world, Roa suddenly sat up from the bed, his whole body covered in cold sweat.
That battle was really thrilling, but fortunately he won, although the price he paid was a bit high.
At this time, Roa felt as if his head had been hit hard, and his whole body felt a little dizzy.
He sat on the bed and rested for a long time before he recovered, and still felt that his condition was not good.
'I overdid it.' That was Roa's first thought at this time.
He got up, rubbed his eyebrows, and turned his gaze to the system interface.
[You have successfully defeated BOSS: Kayaba Akihiko]
[You have greatly participated in and slightly changed the plot]
[Start extracting the power of the source.]
[Extraction successful! You have obtained 30 points of the power of the source.]
[Power of the Source (???)]
[Type: Goods/Energy]
[Level: ???]
[Note: The source of the world, extremely versatile, please explore the specific uses yourself.]
[You have obtained the power of time and space]
[The total power of time and space you have obtained this time is 2000 points]
[The task completion has been increased by 20%]
[You have obtained a total of 2400 points this time]
[You have completed a special task!]
[You have killed ninety floor masters]
[You have obtained a high-level Word of Power awakening *1, injected perfect dragon blood *1]
[You have completely cleared SAO, the world coordinates of SAO will be recorded by the system, and you will receive a chance to consume the power of time and space to adjust the flow of time between the world and the main world.]
A series of system notifications kept ringing in Roa's mind, needless to say.
Although it was his first time traveling through a dungeon, judging from his experience of reading novels in his previous life, the more prompts like this, the greater his harvest.
The power of time and space goes without saying, it is a necessary thing to consume when traveling to other worlds, and it can also adjust the flow rate between worlds, so its preciousness can be imagined.
There was also that power of the source, although he didn't know what level this thing was at the moment, but just looking at the introduction gave people a high-end feeling, and then his eyes swept to the last piece of information.
90 floor masters, it was really not easy for him, he fought desperately with the other party until now, and only then did he get the achievements he has now.
And it took a lot of effort to kill Kayaba Akihiko.
It just seemed worth it now.
While Roa was still sighing and feeling emotional, another system prompt sounded, and Roa looked at the panel again.
[You can choose from the following options and allocate them according to the ratio. Because you killed BOSS: Kayaba Akihiko, you will receive an additional 50%! Your current allocable share: 150%]
[Sword God Style experience and insights]
[Battoujutsu]
[Sword Heart]
[Equipment: Moxie (Rare Quality)]
Roa raised his eyebrows, Kirigaya Naoki's clone definitely had a lot of good things, but there were a little less when it came to him.
With only 150% of the selection right, he definitely had to take all of the Sword God Style's insights, and the remaining 50%, he would take that sword.
Honestly, he used Moxie quite smoothly, subconsciously, he clicked on Moxie.
As a result, the original 150% share directly became 125%
Roa fell silent.
A weapon, requires 125% of the share? Damn it, why don't you just rob me, you dog system?
Roa directly called out the system and asked with a blank expression: "Why is the weapon so expensive?"
[Moxie does not belong to the real world. If you want to convert this item into real data, you need to consume an additional 50% share.]
Roa's mouth twitched, and he gave up the idea of choosing Moxie.
Although Moxie was easy to use, it was not irreplaceable.
Then the remaining choices were actually very few.
Roa pulled the sword skill experience to 100%, and then pulled the level of Sword Heart to 50%.
That was all the gains from Roa's clone going to another world.
After clicking receive, Roa's eyes suddenly went dark.
When he opened his eyes again, he found himself standing in a white world.
"Hiss." Roa gasped.
This reminded him of the bad memories before he was reincarnated.
Before he could think too much, a phantom was standing in front of him at this time.
No, it shouldn't be described as a phantom, it would be more appropriate to describe it as a shadow.
The other party was holding a sword, and Roa was very familiar with that sword, it was Moxie, and Moxie's style was exactly the same as the shadow's style, the originally purple and gorgeous long sword became semi-transparent, with a black and white style.
But inexplicably, Roa felt that this sword was even more handsome.
Looking at the shadow, Roa didn't move, and the other party didn't move either.
When Roa tried to take a step, the originally still shadow suddenly lowered its body, and the famous sword named Moxie was held in the shadow's backhand, and a strong sense of crisis surged into Roa's heart.
This was the classic starting stance of Battoujutsu.
There was no sound, no sound of breaking through the air, just an ordinary slash.
But it was this sword slash that almost separated Roa's entire body.
The warning of Sword Heart was greatly enhanced, and Roa suddenly rolled to the left.
Then he saw a terrifying scene, the shadow that was originally thirty feet away from him appeared in front of him, and the sword in his hand slashed at the position where Roa was originally standing.
This?!
Before Roa could react, the warning of Sword Heart sounded again, and Roa rolled to the side almost without thinking, and narrowly avoided this slash again.
The other party's movements continued, and the other party's sword did not have the slightest momentum, only decisiveness and ruthlessness.
It was clearly just a simple slash, clearly just swinging the sword and drawing the sword, why was it so strong?
For the first time, Roa felt an extreme sense of oppression from himself.
Even before three breaths had passed, Roa was finally beheaded by the other party with one sword, and his vision fell into darkness.
Then he opened his eyes again, and the next moment Roa was still standing in the white world, and opposite him was still that shadow.
In an instant, he understood everything, so that was how the so-called sword skill experience was obtained.
Fighting with that self, absorbing the essence of the other party's sword moves, and then constantly improving, and finally reaching the point where he could defeat the other party?
It was just that it was clearly the experience gained by his own clone, so why did he have to make it so troublesome?
He couldn't quite understand.
Roa tried to use his magic power, but unfortunately, this area was a magic-forbidden zone, not to mention magic power, there were no elements, and the magic power in his body was like being put on shackles, and he couldn't use it at all.
Although his most relied on magic power was banned, the other party was not absolutely impossible to fight against.
But, thinking about it, if he could still use magic power, then this shadow would not be necessary.
It was just that how could there be a lack of weapons in the battle, Roa turned his gaze to Moxie in the other party's hand, and imagined having the exact same sword as the other party in his mind, the white mist rolled, and Moxie appeared out of thin air in Roa's hand.
Roa showed a smile to the other party, and said with a smile: "Then, our battle begins!"
When Roa opened his eyes in reality, he gasped for air desperately, his entire body drenched in sweat.
No one could know what he had been through.
His heart was pierced, his abdomen was pierced, his head was severed by a sword, and his throat was slit.
Roa had experienced every possible way to die, and by the end, he even felt a sense of numbness.
At the moment his body was pierced, he could still feel his heart beating.
At the moment his head was severed, he could still see his surroundings.
At first, the feeling of consciousness gradually sinking into darkness was truly unpleasant. When he opened his eyes again, it was another round of slaughter.
Either he was stronger than his opponent and defeated them, or he would be killed over and over again.
This experience was undoubtedly extremely terrible. The taste of death was not pleasant, and no one would want to experience it even once.
The most important thing was that every time the opponent attacked, they were actually helping Roa gain a deeper understanding of swordsmanship.
At this moment, Roa finally understood what was going on.
The system had summoned this thing to help him quickly grasp the essence of sword techniques and the experience brought by soul-splitting.
He had died nearly a hundred times in that white space, each time fighting with all his might against his opponent. From initially lasting only three breaths, Roa had to think about his opponent's movements after each death, recalling why he had been forced into such a desperate situation before dying.
Under such pressure, Roa's growth speed was self-evident. Almost every death brought him significant improvement.
Fortunately, in this white space, his mental state was fully restored each time he revived. If not for this, he would probably be stuck in this endless cycle of death.
However, while he didn't feel much in the white space, once he returned, he felt even more mentally exhausted.
His already extremely tired mental energy was now completely drained, and he almost fainted on the spot.
Roa controlled his rapidly beating heart, trying to slow and steady his breathing, and once again turned his gaze to the system panel.
[You have gained insight into the Sword God Style. You have now reached the Sword Saint level (max).]
[Your Sword Heart has been upgraded to level 3.]
Roa sighed. He was still just a little short. He felt that he was only a step away from breaking through to the Sword King level. He just needed an opportunity, a chance, to surpass the Sword Saint level and reach the Sword King level.
But the most urgent matter now was to adjust the time flow between the Sword Art Online world and the current world.
[You have obtained an opportunity to consume spacetime energy to adjust the time flow between this world and the main world. Will you use it now?]
"Yes."
Roa focused his mind, and the text quickly changed into two lines of small characters.
[Please select the time flow adjustment.]
Roa directly adjusted the original [1:4] time flow to [1:365].
Then he discovered that adjusting the time flow between [1:5] and [1:365] cost the same—100 points of spacetime energy. Starting from 366, the cost doubled, requiring 200 points of spacetime energy. The time flow could be adjusted forward or backward, and the cost was the same for the same ratio.
This made Roa feel slightly surprised.
It wasn't that it was too expensive, but rather that it was too cheap.
But after a moment of thought, he felt that this price was actually reasonable.
100 points of spacetime energy was not a small amount. In terms of crossing worlds, it was enough to open another instance like Sword Art Online.
Moreover, the key wasn't the amount of spacetime energy but the ability to adjust the time flow, which was the crucial point.
Was Kayaba Akihiko easy to defeat?
Only after killing him could one obtain the coordinates of the Sword Art Online world and the right to adjust the world's time flow. Not everyone could take such a risk like Roa. If Roa hadn't taken the risk, even with Kirito's almost maxed-out stats, he would have undoubtedly died in a direct confrontation.
After adjusting the time to [730:1], Roa clicked confirm, and the prompt sounded in his mind again.
Two years would pass here, while only one day would pass there.
[Successfully spent 200 spacetime energy.]
[The current time flow ratio between the main world and the Sword Art Online world is 730:1.]
Roa finally let out a long sigh of relief. He remembered that there was still a scumbag in the Sword Art Online world. If he hadn't died so hastily, he would have definitely taken that person with him.
Then Roa prepared to turn over and sleep, replenishing his completely drained mental energy. He felt that if this continued, he would die of exhaustion in this other world.
If he really died in bed, he could probably write a novel titled "About How I Reincarnated as a Mage, Obtained a System, but Died of Exhaustion While Claiming Rewards."
Roa had just fallen asleep when there was a knock on the door.
The knock was very polite. Although Roa was mentally exhausted, his senses were still sharp.
Such a gentle knock could only be from Elena. Eris would never show such respect, and Rudeus's knocks would always carry a hint of guilt since he usually came to Roa for help, so it was normal for him to be a bit nervous.
But why had Elena returned?
Roa sighed helplessly and said to the person outside, "The door's unlocked. Come in."
A ten-year-old white-haired loli walked in.
Her hair was like moonlight, and she was about 1.4 meters tall. Her secondary sexual characteristics were beginning to develop, and her face was delicate. However, for some reason, she had become somewhat cold, giving Roa the illusion of looking at his younger self.
Roa lazily sat up from the bed and said weakly, "Elena, you're here? What's the matter? Didn't I tell you to become Princess Ariel's bodyguard?"
Elena looked up at Roa, her tone somewhat helpless. "That princess always wants me to sleep with her, and she always gets handsy while sleeping. Today is a rest day, so I came back to visit my father. On the way, I thought I should visit you too."
Roa's expression gradually became interesting. He seemed to have forgotten that she had a tendency toward lesbianism.
After coughing a few times, Roa put on a serious expression and said to Elena, "Well, you're doing a good job. Keep infiltrating, and at the same time, try to elevate her status. In short, help Princess Ariel more."
Elena nodded, her expression slightly strange. She asked curiously, "You look very mentally exhausted and in poor condition. Do you need my help?"
Roa waved his hand and lay back on the bed, saying, "You go ahead with your tasks. I'll be fine after some rest."
Elena nodded, closed the door, and left the room.
Roa closed his eyes, ready to fall into a deep sleep, when the door was knocked on again.
This time, the knock was very rough—no, it couldn't even be called a knock. Roa felt that if the person outside used a bit more force, they could break the door down, clearly showing the owner's bad temper.
