The next day, Shun and Kaguya stood side by side on the cliff, the clinking of their wine glasses echoing crisply.
The wine, with a faint fruity aroma, slid down their throats.
After a while, Kaguya slowly spoke, "You've absorbed Urashiki's Time Law imprint. This is a good start. But what are your plans next?"
Shun stood beside Kaguya, his gaze fixed on the God tree in the distance.
He was silent for a moment, then said, "I'm thinking, since the God tree is a weapon of the Otsutsuki clan, perhaps it can help me comprehend the law."
Kaguya raised an eyebrow slightly, seemingly intrigued by his idea. She put down her wine glass, waiting for him to continue.
Shun took a deep breath and continued, "When I absorbed the imprint, I could feel that within the Law, there was an even deeper layer of logic hidden. However, with my current ability, relying solely on myself, it would be difficult to fully understand and master it in a short time."
Kaguya pondered for a moment, then softly asked, "So, do you have any specific ideas?"
Shun stared intently at the God tree and slowly uttered two words, "Infinite Tsukuyomi."
"Infinite Tsukuyomi can pull people's consciousness into a genjutsu. If I use it to connect with the God tree and find enough consciousness carriers, perhaps the God tree can help me analyze Time Rewind, much like it analyzes battle situations."
Kaguya was silent for a moment, then nodded. "This method has risks, but it's worth a try. The God tree is already adept at absorbing and converting consciousness energy. If it can be combined with Infinite Tsukuyomi, it might truly accelerate your comprehension of the Law."
The two chatted on, from the characteristics of the God tree to the weaknesses of the main family, from the state of the Ninja World to past experiences.
As night deepened, the aroma of wine on the cliff intertwined with the glow of the God tree, creating a rare tranquility.
It wasn't until a faint light appeared on the horizon that Shun stood up.
"I should go back and prepare. Later, I might need your help to stabilize the God tree's energy."
Kaguya nodded, and only after watching him step into the spatial gate did she turn and return to the God tree.
Upon returning to the Land of Water's Royal Palace, Shun immediately summoned the captain of the Black Ops.
"Transfer all those thousand-plus death row inmates from the prison to the ancestral star where the God tree is. I have a use for them."
The Black Ops captain's face was expressionless as he nodded in agreement. "Yes, Shun-sama."
...
At sunset, more than a thousand death row inmates were neatly lined up beside the God tree on the ancestral star. They were bound by Chakra chains, their eyes filled with fear and confusion.
They only stopped their commotion when Shun and Kaguya appeared.
"You are all people whose crimes deserve death. Today, I'm giving you an opportunity to contribute to the Ninja World. I will not harm your lives, I will only borrow your consciousness. Afterward, I will reduce your sentences."
After speaking, Shun activated his golden Six Tomoe Rinnegan, and the light of Infinite Tsukuyomi burst from his eyes, instantly enveloping over a thousand death row inmates.
The next second, all the death row inmates fell into a deep sleep, their consciousness pulled into a genjutsu.
Shun raised his hand to form a seal, and the God tree's roots suddenly erupted, wrapping around the forehead of each death row inmate like threads, connecting their consciousness to the God tree.
Shun said in a deep voice, "Kaguya, help me stabilize the God tree's energy, don't let the consciousness fluctuations backfire."
Kaguya injected Chakra into the God tree, making its connection more stable.
Shun then walked to the God tree, placed his palm on its trunk, and transmitted a command with his Rinnegan.
"In my name, deduce the Law of Time Rewind, analyze its logic, connect all consciousness carriers, and compute collaboratively."
The patterns on the God tree instantly lit up, and red Chakra surged along its roots into the consciousness of each death row inmate.
Over a thousand consciousnesses, like a thousand high-speed CPUs, began to frantically deduce the Law of Time Rewind under the God tree's coordination.
Some consciousnesses simulated the flow of Chakra during time reversal, some analyzed the correlation between space and time, and others attempted to construct an energy model for rewinding.
Shun closed his eyes, integrating his own consciousness into it.
He could clearly feel countless fragmented Law pieces colliding, recombining, and decomposing in his mind.
The vague "rewind logic" he felt when absorbing Urashiki's imprint now became clear.
Time Rewind was not a simple "tike travel," but rather required first locking onto the target's "time coordinates," then constructing a "time channel" with Chakra, and finally reversing the target's time trajectory.
"So that's it. I overlooked the stability of the time coordinates before."
Shun's mind suddenly brightened. He could feel his control over Time Rewind rapidly improving.
Originally, he could only rewind small-scale injuries, but now he could try to rewind the state of objects around him, such as restoring broken stones on the ground to their complete form.
Kaguya watched the God tree's light grow brighter and brighter, a hint of surprise flashing in her eyes. "I didn't expect this method to actually work. The collaborative computing of over a thousand consciousnesses, combined with the God tree's deduction ability, is at least ten times faster than your solo comprehension."
"It's still not enough."
Shun opened his eyes, a golden current flashing in their depths.
"I don't want to just 'know how to use' it, but to 'master' it. Deduce for another three hours, and we will grasp the core logic of Time Rewind."
Three hours later, a faint light appeared in the east of the ancestral star.
The God tree's light gradually dimmed, and the roots wrapped around the death row inmates slowly retracted.
Over a thousand death row inmates slowly woke up, their eyes filled with confusion, as if they had dreamed for decades.
Shun stood still, surrounded by faint fluctuations of the Time Law. He raised his hand towards a broken rock and softly said, "Rewind."
A pale golden light burst from his palm, enveloping the rock.
The next second, the broken rock slowly returned to its original state, even the patterns on its surface were exactly the same as before.
Shun looked at the rock and excitedly said, "Kaguya, I succeeded. Thanks to your help in stabilizing the God tree's energy, otherwise, I probably wouldn't have succeeded so easily."
Kaguya shook her head, her gaze falling on the God tree. "The God tree also absorbed a lot of time rules from this deduction, which counts as a win-win. However, you must remember that Infinite Tsukuyomi should not be used frequently, as it consumes too much consciousness, and even the God tree cannot withstand multiple such exertions."
Shun nodded, already having a plan in mind. "I will arrange for these death row inmates to cultivate barren land, which can be considered an opportunity for them to reform. Next, I need to thoroughly digest the results of this deduction and strive to master Time Rewind as proficiently as Divine Acceleration and Time Stop as soon as possible."
