Yugeo's right hand was kicked straight upwards, and the Sword of the Green Rose was knocked flying, spinning in circles into the marble that pierced into the ceiling. While capturing this situation in the corner of the high-speed flowing field of vision, Lin Yiyan immediately re-grasped the black sword and prepared to pursue after the end of the somersault and landing.

The sole of the right foot with a light finish touches the ground. Bend your knees, absorb the impact, and jump out as soon as you're settled. With his left foot, he took a resolute step towards the chest of the bare-handed Yugeo, and unleashed a single-shot sword technique Slant that slashed from the bottom left to the top right—

“————！？” What Lin Yiyan, who stood up while leaning forward in an extremely forward posture, saw Eugeo's left hand stretched out to this side, and the green dots of light shining on the fingertips of his five fingers.

At the moment before Lin Yiyan's sword slashed into the brilliant breastplate.

“Burst Element.” A brief gesture came from Eugeo's lips. Spots of light—as many as five wind elementals exploded at the same time, creating an explosive wind that engulfed me. It's just that the wind pressure that was simply released didn't hurt Lin Yiyan, but Lin Yiyan couldn't even stand firmly, and was blown away like rags.

"Goo......!" While losing his voice, he spread out his hands and tried his best to stabilize his posture. If you hit the wall headfirst with this momentum, it is estimated that you will lose more than 10% of your destiny. Although swayed by the storm, Lin Yiyan stopped the rotation of his body, and stretched out his feet towards the approaching wall.

The moment he hit the ground, the strong impact hit the Tianling Gai, and Lin Yiyan stuck to the wall for a while, and only fell to the ground after the paralysis in his whole body disappeared. Raising his face suddenly, Yugeo was rightfully pushed to the opposite wall by the wind, but he didn't seem to float into the air due to the weight of his armor. He leisurely stood up from his slumped position, his face still expressionless, which made people angry.

After a while, I also stood up, and a small voice came from beside me, "...... Is that person really your partner Yogeo? ”

Alice, who followed Lin Yiyan's request and watched the battle by the wall, asked. Lin Yiyan only glanced at the gold-clad female knight, and replied in the same whisper, "What do you mean by this?" Ugeo has been integrated, isn't that what you said? ”

"That being said...... What should I say......" After a moment of rare silence, Alice said something that Lin Yiyan didn't expect, "That person, he just became an integration knight, no, he is too familiar with combat not long after he has been knighted." Whether it was the mental skill he had shown before the battle, or the wind elemental technique he had just used, it was impossible to imagine that he was a novice. ”

“…… Isn't that kind of technique something that can be mastered at will after becoming an integration knight? Although it was only confirmed just in case, the reprimand flew from the side indiscriminately, making Lin Yiyan reflexively shrink his head even in this situation.

"A knight's skill isn't such a casual thing! Needless to say, the Mind Technique and the Armed Complete Domination Technique, even the true meaning of the Secret Meaning and the Divine Technique require a long period of study before they can be turned into one's own use! ”

"That's right. …… However, in that case, what was going on just now...... Obviously, that guy Eugeo can't create five elements single-handedly......"

"That's why I'm asking you. Is that really Eugeo? ”

"............" Lin Yiyan closed his mouth and stared at the blue and silver knight who was slowly walking towards this side.

The High Priest Administrator, who lives on the hundredth floor of the Central Cathedral, directly above this level, is the ultimate divine sorcerer alongside Cardinal, the sage of the Great Library. Since this opponent can use terrifying techniques such as altering human memories, it is not impossible to even make fakes that look exactly the same. But—

“…… It's Eugeo. Lin Yiyan muttered in a hoarse voice.

Even if his eyes are dull, his face is bloodless, and there is no smile on his mouth, that integration knight is the partner and best friend of Lurid's Eugeo himself. Although he has made several mistakes in this world, this is the only thing that can be determined.

Not long after he was knighted, he was able to master skills that even the third-ranked master Alice was shocked by, and Lin Yiyan didn't know why. Until then, it was not clear why the forced integration, which should have taken three days and three nights, ended in less than an hour. However, no matter what the anomaly is, there is only one thing that needs to be done. Pour everything you have into your sword and fight to the end. That's all.

Take a deep breath and exhale, regaining your grip on the black sword. Perhaps sensing my fighting spirit, Eugeo also stopped in the middle of the hall and silently raised his right hand. With an invisible mental skill, he pulled out the sword stuck in the ceiling and returned it to his master's hand.

That's right——, the proud sword of the green rose will not be subservient to the impostor. Eugeo easily turned the unnaturally heavy artifact a few times, then placed it just right in the middle. Looking at the flawless stance, Alice whispered, "Let me be his opponent." ”

"Don't talk stupid." After immediately denying it, Lin Yiyan put the love sword on the front of his body. Although they have lost their memories of each other, Eugeo and Alice are childhood friends who grew up together in the village of Loulid. Rushing to this point will not make these two people fight, and most importantly, it is his task to wake up Eugeo.

Although Alice was enraged by Lin Yiyan's "stupid" speech when hanging from the outer wall of the cathedral, now she stepped back without saying a word and clasped her hands in front of her chest. After learning that the knight meant that even if she was cut down, she would never make a move.

“…… Thank you. Lin Yiyan responded softly and switched consciousness.

From this moment on, forget everything that is not necessary in battle. Integrate with the sword and challenge yourself with all the skills you have mastered. If you don't, you won't be able to defeat the integration knight Eugeo, nor will you be able to pass on anything to the heart of your best friend Eugeo, who is supposed to exist deep in the thick armor.

The blade of the black sword trembled slightly. Just as the day of departure two years ago, the aftermath of thunder in the distant sky traveled through time.

- It's up to you, partner.

- I'll give you a name when all the battles are over...... Give me a hand.

After silently reciting the love sword in his right hand, Lin Yiyan took a deep breath again and stopped suddenly. All the noise, the background, even the temperature is gone. In the horizon there are only himself and the Black Sword, the Eugeo and the Sword of the Green Rose. Since two years ago, I have been fearing from the bottom of my heart and waiting for this moment to come.

- Come on, Yogeo!!

Bursting out with a silent roar, Lin Yiyan slammed into the ground. Yugeo still held his sword in the middle and remained motionless, waiting for Lin Yiyan's attack.

For Yugeo, who is now able to wield the Sword Technique of the Ain Grant Stream and the High Divine Technique as he pleases, the little tricks will not work. In the blink of an eye, he crossed a distance of fifteen meters and unleashed an upper-right slash with unreserved spurt speed. On the other hand, after taking a step through the ground, Yugeo held his sword in both hands and picked it up from the lower right.

The blades of pitch black and silver collided violently, emitting dazzling flashes and bouncing back. Judging that it was not possible to distinguish the winner by secret meaning at this distance, he held his left hand on the handle and held it with both hands. Following the force of inertia attached to the heavy sword, after drawing the shortest trajectory and raising the sword high above the head,

"Whoa, whoa!" Transform all the accumulated air into momentum and swing your sword down.

If the size of the sword and the skill of the swordsman are the same, it is impossible to completely block the vertical slash with all the power by means of a horizontal or oblique slash. The only way to do this is to use the same skill with the awareness of canceling each other out, or to escape the range of the sword, and choose one of the two.

However, due to the blow just now, Yugeo's sword slashed to the right and could not be raised. Moreover, the center of his body is also skewed to the right, and he cannot jump back quickly. This time, it was able to hit——! Throw aside all the hesitations that dull your skills, and swing your sword away. The blade of the black sword captures the left shoulder of Eugeona, protected by the blue-silver armor.

No matter how high the priority of the Fusion Knight's armor is, the defense will not be enough to bounce back the full force of an artifact-level weapon. The sword unleashed a sharp metallic sound and slashed into the armor, slashing directly below with a momentary sense of resistance. A streak of light traveled in a straight line from Eugeo's left shoulder to his chest.

Immediately after, the sound of glass shattering sounded, and the heavy armor shattered. Fragments of metal fluttering in the air, mixed with crimson droplets. Judging from the feel, although it was not a serious injury, Lin Yiyan's sword finally slashed into Yugeo's body.

At the moment when he realized that he had hurt his best friend, Lin Yiyan also felt the pain of being slashed in the same part. Although I couldn't help but wrinkle my face, I couldn't stop here. Pull back your wrist the moment the vertical slash hits the ground, and use the elasticity of your whole body to perform the upper slash of the pursuit-

With a dull impact sound, the black sword was bounced to the front. Although Yugeo had just been slashed from his left shoulder to his chest, the pain did not stiffen his body for even a moment, and Lin Yiyan's sword was kicked away by him with the shin armor of his right foot.

Sensing that his movement was a step to fight back, he desperately turned his body sideways in a tremble. At the same time, the sword of the green rose roared from the left. Although it was difficult to avoid a direct blow to the head, he couldn't completely avoid it, and his left shoulder was slashed horizontally. Feeling the freezing cold that was different from the pain, Lin Yiyan resolutely kicked up with his right foot to the ground, and slammed his injured right shoulder into Yugeo, who had just swung his sword.

The dizzying pain opened at this moment, and drops of blood fluttered in the air. On the opposite side of the red mist, Lin Yiyan saw that Yugeo stepped on his left foot hard and stood firm before he was about to fall. In that position, it is impossible to fight back immediately. Lin Yiyan changed the love sword back to holding it with one hand and held it to the upper right. The black blade is then enveloped in a vivid aqua glow.

Secret mystery, single-shot diagonal slant. If this blow could hit Yugeo's right shoulder, then he shouldn't be able to swing his sword as nimble as he did when he was wounded on both shoulders.

"Ah...... Yes! "The moment when you shout and are ready to unleash your skill. The inside of Eugeo's body bursts with crimson glitter. It is the light of the sword technique. However, attacks that can be performed with the right back facing the opponent do not exist in the Aingrant stream.

Even Lin Yiyan's eyes widened in shock, he couldn't stop the sword now, and the Slant had been activated. After a split second, Yugeo's body spun violently counterclockwise. A horizontal slash from left to right drew a trail of red light.

That sword move...... It is a two-handed sword single-shot skill Backlash. When the opponent is in a position behind the back, this is a counterattack technique aimed at reversing a single blow. However, Lin Yiyan has never taught this skill to Ugeo. The impact shattered the thought and blew it into dispersion. Lin Yiyan's Slant and Ugeo's Backlash collided violently, and the swords of both sides were violently bounced away again.

As the blood drew dotted lines from each other's shoulders, Lin Yiyan and Yugeo raised their swords directly above them in exactly the same motion. The two blades burst out with a deep blue light.

Single Vertical Upper Slash, Vertical.

If it is vertical, it is usually tilted about 10 degrees to the side of the dominant hand, so if two people face each other and use it at the same time, the tracks will cross each other, and they will bounce back to the rear after the collision.

This time, the same is true until halfway through. The black sword collided with the sword of the green rose about a third of the way down the tip of the sword, sending out dazzling sparks.

However, unlike the old SAO, it is not uncommon for sword skills and sword skills to collide with each other without being reflected back in Under orld. I'm afraid it's each other's fighting spirit – imagination, in other words, mind – that inhibits the repulsion of the system.

The two swords crossed as if they were biting into each other, bursting with a large number of orange sparks and blue light. Lin Yiyan and Yugeo began their third encounter, and at the closest distance, their faces were close to each other, and their swords and right hands creaked as they completed their respective sword skills.

Lin Yiyan stared into Yougeo's eyes through the flying sparks, and asked as he squeezed out a voice from between his clenched teeth, "...... Do you have a name for the trick just now? ”

With an expression like frozen water, Yugeo whispered, "...... Valtio current, against the waves. ”

Where did you hear the name of the genre, Lin Yiyan couldn't recall it immediately. After frowning and thinking about it, I finally noticed. Valtio Stream. It was until March of this year, when Yougeo was in the Northern Santoria Sword Academy, serving as an attendant trainer of the high-level sword cultivator Grugloso Barruto.

Because it is a crude and unadorned sword system compared to the Norgia and the High Norgia Stream, it is despised by the students of the upper nobility like the Celluloid of Sister Soltilina I serve. On the flip side, however, it means it has real combat value. During the year that Yugeo was in attendance, Senior Grugloso must have enlightened him of this genre.

In this way, there is another mystery here that cannot be ignored.

"Eugeo...... Do you remember the person who taught you this sword technique? Lin Yiyan injected all his strength into the intersecting swords and asked again.

A moment later, the expected answer came, "I don't know, and I'm not interested." Although he should have done his best like Lin Yiyan, both his voice and expression were extremely cold and stiff, "I just need to remember that person." I held the sword for that man, and drove out that man's enemies, so that I could survive here......"

"........." Sure enough, not only himself and Alice, but also seemed to have forgotten everything about Senior Grugroso. On the other hand, the name of the sword technique and how it was used are still remembered.

If all the memories of the human who became an integrated knight are reset, they will lose the sword skills and sacred arts they have cultivated up to that time. So the High Priest Administrator wrote a complex process called the Ritual of Integration.

Rather than completely erasing the subject's memories, it prevents him from recalling them by blocking the flow of memories. Although the exact logic is not clear, it can be said that it is similar to retrograde forgetfulness in the real world, which is a symptom of memory loss that retains the ability to speak and live even after losing one's memory and those of those around you.

The obstacle that blocks the flow of memories is the Worship Module inserted into Fluct Light, the soul of Yogeo. Now in the field of the module, whose memory is there? Obviously, as long as you figure this out, you might be able to wake up Yugeo.........

Wrong. Words alone are not enough to break the Administrator's sorcery.

The sword of the imaginary world has a meaning that is better than that of an object made up of polygons. It is precisely because you entrust your own life to it that what is injected into the blade can reach the soul of the other person. The sword freed from hatred is able to transcend words at certain times and bring people to heart-to-heart communication. Lin Yiyan is so convinced.

The blue light of Vertical, which enveloped the two swords that were biting, faded as if canceling each other out. It is time to take advantage of the present moment and rack up the last bit of the remaining strength. In order to pass on everything he knows to the hearts of his best friends.

"Excellent ...... Geo ——————!! The moment the sword technique ended, Lin Yiyan shouted and raised his sword high.

Do whatever it takes. was bounced off. Eugeo's slash. Bounce off with the root of the sword. The two of them stopped together, swinging their swords in the shortest distance. The twin swords unleashed endless impacts and sparks, filling the surrounding space with sound and light.

"Oh...... Oh, oh————!! ”

Lin Yiyan roared.

"Hey...... Ahh————!!h ”

For the first time, Yugeo also let out a roar.
