Hakushi then reached his hand into the purple beam of light and took out half of a crystal.
This was half of the Dragon Vein Core.
Hakushi sensed the dense Chakra contained within the half core, nodded satisfactorily, and put it away.
Changing the seal, he transformed it into a sealing style, causing the device in his eye to reabsorb the purple Chakra that was spilling out, and he returned the half of the Dragon Vein Core that he didn't take back into safe storage.
It wasn't that Hakushi didn't want to take that half, but the power of the Dragon Vein was connected with the entire Roran.
If he took the entire Dragon Vein Core, it might cause the entire Roran to fall into destruction.
But if he didn't take the core, Hakushi worried that people from other timespaces might use the Dragon Vein of this world to descend, leading to disorder and historical disruption.
So he had to compromise, taking only half.
This ensured the normal operation of the Land of Roran and significantly diminished the power of the Dragon Vein, preventing the forbidden ability of time-space traversal and stopping such activities from happening.
Hakushi turned his head and saw An Lushan, whom he had killed, his body glowing with particles of light, slowly melting into the air.
"It seems time-space has finally returned to its normal order. Fortunately, this guy came to this world but only conducted hidden activities in such an isolated country like Roran, causing minimal historical changes..."
If he had gone out and announced the future history, it could easily have led to global chaos and unrest throughout the entire Ninja Realm, a disaster more terrifying than the Ninja World War.
If one says that war is merely the inevitable result of human history, using predetermined future history to disrupt the past, the disaster's extent is unimaginable, even for Hakushi, and could cause severe consequences.

At the ruins.
"What is going on?"
Naruto and the others were startled, seeing themselves enveloped in a white light.
"It seems the issue there has been resolved. The medium that brought you to this world has been dealt with, so the time-space order on you has returned to normal."
Ruri and Ayane just watched Konoha's four ninjas' unusual reactions without any actions.
"Really, it all feels like a dream."
Yamato scratched his head, unsure how to express his inner shock.
"Well, goodbye then."
The relationship between them was not exactly amiable, and in another time-space, it was viewed as an adversarial relationship, so Ruri and Ayane just bid a simple farewell and left.
Yamato and the others watched their backs, turned into points of light like particles, slowly disappearing into the air, silently bidding farewell to the unfamiliar time-space that did not belong to them.
——Finding Hakushi was something that happened half an hour later.
"Did those Konoha ninja go back?"
Hakushi, posing as a traveler, rented a room in a Roran city inn.
He was dealing with the future traces left by An Lushan, destroying various items brought back from future times by placing them in the fireplace.
"They have already gone back. How about the power of the Dragon Vein?"
Ayane sat on the soft bed, observing the layout of the room.
"Recovered half."
"Only half?"
"It's enough. After all, I can't take it all. The people of Roran still need that half of the Dragon Vein to maintain their lives. And since I took half of the Dragon Vein, its power has greatly diminished, sufficient for sustenance, but achieving time-space conversion is now impossible."
Hakushi explained simply.
"Very considerate."
Indeed, if the Dragon Vein were to maintain its full power, someone might use this power later to disrupt the time-space order.
This is much more serious than a Ninja Realm war, and could lead to the collapse of human history.
"Next, we still need to deal with our matters."
After placing things into the fireplace to burn, Hakushi stood up and said.
"Our matters?"
Ruri and Ayane looked at Hakushi with confusion.
"Unlike the people of Roran, in their memory, An Lushan belongs to this era, which doesn't threaten this world's order. But the three of us are different. Our influence over history is far more terrifying than that of the isolated Land of Roran. The memories regarding An Lushan and those Konoha ninjas must be reasonably erased."
"..."
Ruri and Ayane's faces suddenly turned stiff.
Seeing their expressions becoming so stiff, Hakushi knew what they had done before.
"You two...when you were watching those Konoha ninjas, you must have asked them about the future, right?"
"No...we actually just learned a little bit."
"Even a little bit is not acceptable."
Seeing Hakushi's serious expression, Ruri and Ayane knew that no matter what they said, it was impossible to change his mind.
"That was hard-earned precious information... And those Konoha ninjas didn't have their memories erased."
"That's another time-space, completely unrelated to us. Let those people from that time-space worry about it. I have taken half of the Dragon Vein's power here, so even if the ninja from that time-space wants to use the Dragon Vein to traverse time-space to do something again, they would end up in another time-space causing trouble and never reach here again."
Without caring for Ayane's pitiful look, Hakushi placed his hands on the foreheads of both Ruri and Ayane, erasing all the memories of An Lushan and those Konoha ninjas from their minds.
Afterward, Hakushi used a Sealing Technique on himself, deleting this part of the memory but only leaving the important memory of secretly thwarting the plot of Roran's minister An Lushan, inadvertently saving Roran, and taking half of the Dragon Vein.
