Xin wasn't trying to trick Sasuke this time.
He was telling the truth, he just hadn't expected this kind of result.
The description of this jade within the system was:
Those with the aptitude for the Heartless Sword can use this sword intent to begin their training. A small number of those without aptitude will be enslaved by the sword intent and become sword servants within a specific time period.
If Sasuke could truly achieve heartlessness, this would be incredibly powerful.
He could directly enter the realm of sword intent and become a master swordsman from then on.
But now it seems...
Not only does Sasuke lack the aptitude for the Heartless Sword, but it might even be the opposite.
Indeed... he's definitely a tsundere.
"You don't need to be disappointed." Xin helped Sasuke up and brushed the dust off his shoulders. "Hatred is not heartlessness; on the contrary, it belongs to having feelings. You were enslaved by the sword intent because of your inner resistance. There's more than just this one path for swordsmanship, and besides, aren't there still Mystery Box?"
"..."
Sasuke seemed to have recovered slightly, but fear still lingered in his eyes.
The Heartless Sword was actually like that.
Turning oneself into a sword, that feeling...
Sasuke, still just a child, couldn't help but shiver.
Forget about training.
He didn't even want to experience that feeling again.
Fortunately... there were other sword paths.
Color finally returned to Sasuke's eyes. He looked at Xin again, that hint of self-satisfaction having vanished without a trace.
"Excuse me, are the other sword paths also this strong?" he asked.
Although that feeling of heartlessness was terrifying, the power was truly immense.
Sasuke had to admit it.
Right now, he hadn't even entered the door of swordsmanship. His current strength was just the beginning; he still needed to become much stronger!
"Didn't I already say?" Xin gave a gentle smile. "The Heartless Sword is just one of tens of thousands of sword paths, but..."
"But what?" Sasuke became nervous.
"Any powerful force cannot be cultivated simply. Just like the Heartless Sword, it requires the corresponding aptitude." Xin seemed a little helpless.
"Aptitude?" Sasuke was startled.
"That's right. For swordsmanship, aptitude is—" Xin uttered two words, "Sword Body."
Finally, it was time for the part he had painstakingly prepared.
One of the biggest charms of opening Mystery Box is having a grand prize that makes guests extremely excited.
For Tsunade, the grand prize was resurrection.
And for Sasuke, the grand prize Xin arranged was the Sword Body.
This was truly a good thing.
