Killing Xianxia Protagonists With An AI System In Another World!

~Hey, can I offer a suggestion? Tell her to call you onii-chan. And for her new name... how about... Ai?~

It was the entity who controlled the faith energy of Modern Earth! He had yet to disappear!

~Don't just refer to me as an entity. My name… you can call me QQ.~

"Well then. You can call me 'onii-chan' and as for your new name… how about 'Ai'?" Shu Yidan acted as if there was no transmission at all.

[Thank you for naming me, onii-chan. Ai sounds like a splendid name.] The System – no, Ai, twirled her fingers in a moe gesture as she replied.

Unfortunately, Shu Yidan's attention was focused on the newly-named QQ's transmission.

~…What do you want?~ Shu Yidan sent off a message using divine sense to maintain the privacy of their conversation.

~Nothing much, now. The awesome QQ has already left, this is just a recorded transmission. And seriously, while your way of weaseling out of our agreement is acceptable, that's still kinda scummy. Whatever, I don't really care as long as you stick it in a girl sometime soon. Ta-ta, see ya.~ With that, the voice disappeared.

Shu Yidan couldn't help the cold glare surge in his eyes. That was an indirect threat!

[Onii-chan, are you listening to me?] Ai's voice resounded in his ear. He was shaken out of his rumination.

"Yeah, I am here… What were you saying?" Shu Yidan didn't bother hiding the fact that he wasn't paying attention at all.

[…Nothing important.] Shu Yidan was a bit puzzled at that, but shook his head.

"Oh, I don't mind hearing unimportant things. I have been troubling you with my meaningless rants for a long time after all…" Saying this, Shu Yidan waited.

[Actually… I was thinking… For you to call me your sister, isn't it a bit… excessive?

I don't think I am worthy of being your family…] Hearing the haltingly spoken words in a shy accent, Shu Yidan gently patted the AI-stuffed-into-human-shell's head.

"Honestly speaking, you are more worthy of being my family than anyone else. To begin with, you are someone that is willing to support 'me' and not 'Shu Yidan', the one unconditional support that I have in this world. That is more important than anything else."

"In terms of 'home', I honestly think of this frozen space as homelier than anywhere in the Heavenly Wind Sect." Shu Yidan thought of the day before when he couldn't help but fear the time-stop mechanism of the System. And then, he spent 150 years talking on and on to the System, after which this place suddenly became homely.

"Thus, even if we don't share the same blood, we are similar in spirit. And as a transmigrator, this isn't even my body. My true self is here beside you. Your true self is beside me. Is that good enough?" Shu Yidan finished off his statement with a toothy grin.

There was a pause, as expected. And then came a shortly worded sentence.

[…Yes, that's enough.]

The faint blush on her face like an embarrassed little sister got Shu Yidan's smile to widen. The two looked at each other before Ai turned her head away.

[Don't make me embarrassed… Bad onii-chan.]

Hearing those words, Shu Yidan began ruffling Ai's hair. "Haha, if I don't embarrass you, who will I embarrass?"

The System-stuffed-into-human-shell grasped his hand, before immediately taking it back. [Onii-chan's hand is warm…]

Shu Yidan couldn't help but try to grab her hands once more. "Yeah, Ai-chan come grab onii-chan's hand, let's hold hands together…"

After a little chase scene and a little cornering scene, loads of hand holding occurred.

Returning to more serious talk…

"…So, the new ability has been loaded?" Shu Yidan couldn't help but anticipate it.

The System's new ability would certainly be biased to the fate-infringement and data-gathering stream… It would likely be helpful in tracking down that rapist before he could do too much damage.

[Yes. Here it is…] Saying this, a blue screen appeared before Shu Yidan.

[Ability Name: Chronicle Unbound]

[Ability Source: Restricted Spirit Crystal – RXW7651]

[Ability Description: Scry into the past of an object and using the threads of karma, gain insight into the historical experience with a first-hand look.]

"…Basically, it can allow one to synchronize with the past of an object to learn the skills of its wielders, huh…" Shu Yidan knew a similar technique which could be used by array, though it required loads of preparations and the insight gained was pathetic.

This skill could likely surpass it, allowing him to master any technique simply with a touch of an antique.

But that didn't explain how it would allow him to settle the karma with his predecessor, unless…

"This skill… can be used on my body?!" Shu Yidan couldn't help but ask.

[Of course. You can resolve your karma with a single thought and come to know the chronicle of your predecessor.] Ai's face was smug, thinking highly of herself.

But Shu Yidan felt it was only natural. It was a skill that was worth praising, even by the former True Immortal Shu Yidan.

"Since you have that ability from the Restricted Spirit Crystal – RXW7651… then, how about the other abilities from it?"

Restricted Spirit Crystal – RXW7651 was the item that was meant to revive his Blade Spirit Hua Xiu. It was an artifact that could piece together even shattered souls. It functioned on a principle relevant to storage devices: that even permanently deleted data can be brought back as long as traces of it remain in the system. Considering Shu Yidan's body as the system and the predecessor's soul as the deleted data… could it possibly… bring the predecessor back?

[Yes, the other abilities can be gained as well, but installing them will require Mission EXP. Don't worry, the ability to piece together your predecessor's soul is in the list as well!]
