Kirito and Heathcliff, as well as all the players around them, all stopped moving at this moment, and even held their breath involuntarily.

Immortal_Object, i.e., the existence of an indestructible one.

This is an attribute that players will never have.

All the players present looked at these two English words in amazement, and they still did not relax until the system information slowly disappeared.

In the silence, Kirito slowly lowered his sword and leaped back slightly, widening the distance between him and Heathcliff.

"Immortal attributes? What's going on? Kirito's good friend Klein was the first to break the silence and ask the question that everyone except Kirito was confused about at the moment.

Heathcliff didn't answer, just stared at Kirito with a cold face, and Kirito involuntarily clenched the sword in his hand and replied: "This is the truth, the reason why this man's HP bar never drops below half is because he has the protection of the game system...... The only person who can have the immortal attribute is the system administrator except for the NPCs, but in this death game, only one person has this permission......"

"Alone? You mean......" Akyl's eyes widened incredulously at Heathcliff.

Kirito nodded, looked at the noncommittal cardinal, and continued, "...... Actually, I've been wondering since I came into this world, where exactly is that guy observing us now, but I've always forgotten the purest truth that any child knows—"

"It's like, 'There's nothing more boring than standing around and watching people play role-playing games,' and I'm right, Akihiko Kayaba."

When this is considered forbidden. As soon as the name of the taboo came out, the silence around it was filled with a complete freeze that made people from the soul to the body completely freeze.

Heathcliff stared at Kirito with a blank expression, and after a while, he turned his head slightly to him and asked, "I'm curious, why did you notice this?" ”

"Originally, I was just curious that you could be so strong, but then when you invited me to fight, the speed at which you burst out at the last moment was ridiculously fast."

"I see, that's really my negligence, because I didn't expect you to exert the [Second Knife Flow] to that extent in this period of time, causing the extreme assistance of the system in the duel to have an effect."

This is undoubtedly an acknowledgement.

The corners of Heatscliff's mouth lifted slightly, revealing a wry smile of annoyance, and then continued: "But, just this little bit of evidence, you suspect that I am Akihiko Kayaba?" ”

"I don't suspect that there is someone else who doubts your true identity, that is, Seijun, who suddenly left the front line not long ago and gave up the strategy operation, and it was he who told me the truth that you are Akihiko Kayaba."

Kirito's reply was obviously a bit unexpected by Akihiko Kayaba, so much so that even a person like him who lacked emotions couldn't help frowning.

"That guy? He's really always doing things that make people scratch their heads! Kayaba Jinghiko couldn't help frowning, if Kirito guessed his identity, then it was somewhat understandable, after all, the two sides had been in contact for too much time, and it was inevitable that some clues would be revealed for the other party to notice.

But how did Yi Tiancheng guess his identity, Kayaba Jinghiko really couldn't think of a reason.

And what made him even more incomprehensible was what Yi Tiancheng wanted to do here?

The other party is also the driving force behind the SAO plan, and if you want to save these lambs, you only need to reveal the truth that after the player dies in the game, it will not be realistic and synchronous.

The only logical inference is that Yi Tiancheng wants to expel him from the game and continue to stay in the Ruby Palace on the 100th floor, waiting for the players to come to the door.

If that's the case, then it can only be said that this guy is really, as bad and capricious as ever.

"I was originally scheduled to announce this matter when I was on the 95th floor, but since it has been exposed in advance, there is nothing to hide. That's right—"

After looking around at all the players present, Heathcliff once again showed a detached smile on his face, and solemnly announced: "I am Akihiko Kayaba, and I am also the final boss who will wait for you at the top." ”

This sentence was uttered by Heathcliff, that is, Akihiko Kayaba herself, completely shattered the last trace of persistence in the hearts of the players present, especially the members of the "Blood Alliance Knights".

In the room, the faces of many players showed uncontrollable indignation and hatred.

And those core members of the "Blood Alliance Knights" couldn't help but show their tragic and desperate negative emotions.

At this time, a major cadre of the "Blood Alliance Knights" struggled to stand up as best he could, and his small eyes, which looked resolute and wooden, glared at Kayaba Jinghiko angrily, and he couldn't help but roar: "You guy...... You guy...... How dare you put our loyalty and hope ...... It's a complete waste of ——!."

He clenched the knight's spear in his hand, roared angrily, and rushed out towards Akihiko Kayaba—

However, the Kayaba action was a step faster than him.

Seeing that he waved his left hand and manipulated it casually on the window where he appeared, the spearman's body suddenly stopped, and his personal state was directly paralyzed.

Even so, his hand did not stop, and he continued to operate the window.

"Stop!" Seeing that the situation was not good, Kirito immediately shouted loudly, but it was too late, Akihiko Kayaba's order had already been issued, and the spearman player was directly in front of everyone's eyes, and the blood groove was instantly emptied, and the whole person turned into glass shards and disappeared in place.

"Mix! Egg! You guy, unforgivable! Absolutely unforgivable! ”

Kirito roared with tears in his eyes, his hands holding his sword trembling uncontrollably, and then put on a battle stance.

"In this situation, you dare to raise your sword against me, you really deserve to be valued by me! Now that things have reached this point, there is no choice but to go to the "Red Jade Palace" on the top floor first and wait for you to arrive. Until then, though—"

After Kayaba Jinghiko stopped talking, his eyes that made people feel pressure stared at Kirito, who was not far away, and suddenly smiled: "Kirito, since you are so determined, then I will give you a chance, give you the opportunity to have a one-on-one duel with me here now, and continue that battle without a winner." ”

"Don't worry, I'll remove the immortal attribute, and I'll also suspend the use of GM permissions, if you can win, then even if the game is completely attacked, all players can log out from this world, how about it?"

"No! Kirito! ”

"Deputy Commander! Don't promise him! ”

"Kirito! Don't be impulsive! He's trying to kill you now! ”

Kirito turned around and saw his in-game friends Achill and Klein and the others, all trying to brace themselves up, anxiously calling his name, trying to dissuade him.

"I'm sorry! I can't escape at this time! Kirito looked at everyone for a moment, then took a deep breath, turned his head to look at Akihiko Kayaba, and said in a deep voice: "I can't ask for it, let's fight it out here!" ”

As he spoke, he slowly walked towards the other party and drew his other sword as well.

"Very well, for your enlightenment, I will also travel my own commitments, and let both sides fight at full state."

Kayaba Akihiko gave two commands in succession, and all the players present appeared in a state of paralysis except for him and Kirito, and all collapsed to the ground unable to move.

Immediately after, the blood volume of the two of them was fully restored, and the system information of the immortal attribute was also lifted in the status bar on Kayaba Jinghiko's head.

After doing this, Kayaba Akihiko removed the window, pulled out the long sword that had been stuck in the floor earlier, and placed the cross shield behind him.

Kirito's consciousness was also calmer than ever, and before the battle, after sending a text message to the other party according to someone's instructions, he shrank his right foot back, moved the sword in his left hand forward, and lowered the sword in his right hand, assuming his own fighting posture.

In the room, the atmosphere became more and more solidified.

This is no longer a duel, but a bloody battle with the purpose of killing the other party.

Whether it's Kirito or Akihiko Kayaba, there is no shortage of such awareness in their hearts.

In the next second, Kirito suddenly kicked his leg on the ground, and the whole person rushed up instantly, and the sword in his right hand was directly swept and slashed at the opponent's cross shield.

The sparks flew away, illuminating the cold and solemn faces of the two for a moment.

Battle, on the verge of breaking out......

……

On the other side, Yi Tiancheng, who was far away in the underground labyrinth at the bottom of the ground, also received two text messages one after another.

Although he was not at the scene, he still knew the progress of the situation in the boss room on the 30th floor.

After confirming that Kayaba Jinghiko had suspended the system permissions, the corners of Yi Tiancheng's mouth also hooked up a pleasant smile, staring at the dark figure in the distance, and launched a long-planned action.

Faced with this almost insoluble situation, Yi Tiancheng used the concealment skills he had mastered in his previous life for the first time, combined with the assassin's rank skill [Breath Mask] and the movement method of [Seven Nights Assassination Technique], and almost exhausted his limits, and finally successfully broke into the safe room before being locked and attacked by the boss......

The so-called safe room is actually a complete cube space, with only one entrance, and there are no windows and gaps in it, nor any decorations, only a polished black cube stone table, which is placed in the center of the space like taking root.

This small space was originally the game administrator, that is, the GMs exercising their authority to set up the manual control system, and the pitch-black stone table in the center was actually the console.

Yi Tiancheng stood quietly in front of the stone table, staring at the empty tabletop, as if there was something on it that could not be seen, but he was deeply obsessed with.

When his fingertips touched the mirror-like smooth desktop, several beams of light suddenly appeared on the entire pitch-black console, and then a 'bang' was heard, and a blue-white virtual keyboard appeared on the surface, and at the same time, a huge window popped out with a 'bang', projected on the pitch-black wall in front of him.

Yi Tiancheng bent his finger on the virtual keyboard, typed out the three letters 'Yui', and then clicked the enter key.

In the next second, it was as if some kind of preset program was opened, and the data encoding for high-speed movement was constantly piled up.

On the pitch-black console, a light lit up the entire room, and after the light dissipated, a small Lori the size of a palm appeared.

The little guy is wearing a black and red gothic princess dress, which sets off her delicate and pure white skin in alabaster, her long black hair shines brightly, and her delicate facial features with exotic flavors are like the little goblins and little succubi in the Western fantasy world, exuding indescribable seductive charm.

If you ignore the temperament and decoration of the little Lori and just stare at her posture, then as long as you have seen the work of "Sword Art Online", you will definitely be able to recognize the appearance of this little elf, which is actually the artificial intelligence AI Yui in SAO.

The long eyelashes began to tremble, and the closed eyes slowly opened, after seeing Yi Tiancheng in front of him, the little guy tilted his head slightly, stunned for about a second interval, and then showed a warm smile, and called happily: "Dad~!" ”

Yi Tiancheng breathed a lot, and the expression on his face began to soften rarely, nodded with a smile, and carefully held the little guy in the palm of his hand.

That's right, Yui is his plug-in.

Although the SAO game was originally developed by Akihiko Kayaba, it is actually managed and maintained by a large system called "Cardinal".

The system has the ability to self-judge and is itself designed to be maintenance-free.

Whether it is the refresh of monsters, the AI of NPCs, or the balance of the explosion rate of props and equipment, or even the examination and combing of the player's mental condition, it is all operated by "Cardinal".

And under the secret instruction of Yi Tiancheng, Higajian changed the artificial intelligence No. 1 Yui, who was originally only responsible for the "mental state management support program", into the main program of "Cardinal", which has management authority second only to Akihiko Kayaba.

At the same time, Higajian also implanted Yui with settings such as treating Yi Tiancheng as his father and unconditionally obeying Yi Tiancheng's orders according to Yi Tiancheng's request.

That's why Yui called Yi Tiancheng so affectionately the moment she opened her eyes after she appeared.

"Yui, time is urgent, hurry up and help me turn on the [Extreme Assist] function."

"Okay, Dad."

Yui immediately popped up the management window and began to output relevant instructions-

“…… Who's-your-daddy……”

In an instant, Yi Tiancheng's personal state solidified a bunch of protections such as [Invincible], [One-Hit Kill], [Extreme Full Level], [Extreme Attributes] and so on.

Yi Tiancheng walked out of the room in one step, looked at the boss who was wielding the Death Scythe at him outside the door, raised his hand with a sword, and directly killed him in seconds.

"I'm sorry, but you can really do whatever you want."

Yi Tiancheng smiled heartily, and then the whole person disappeared in place, and directly teleported to the boss room on the 31st floor that no one had reached......
