In the living room of a room in the Uchiha clan compound in Konoha, a cake covered with lit candles sat on the table.
Uchiha Mikoto smiled brightly at Uchiha Yunqing and said, "Happy birthday, Yunqing!"
"Thank you, Mikoto!"
Uchiha Yunqing smiled warmly, but the next second, he suddenly froze. A flood of memories and images surged into his mind, accompanied by a mechanical voice:
[Ding! Detected host awakening past life memories. System activation initiated… Activation successful. Congratulations to the host for binding the sign-in system.]
But at this moment, Uchiha Yunqing couldn't care less about the voice. The overwhelming amount of memories made his head feel like it was about to explode.
"Hiss…"
He covered his forehead with his hand and groaned softly, immersing himself completely in digesting and absorbing the memories.
"Yun Qing, what's wrong? Are you alright? Is something bothering you?"
Uchiha Mikoto, noticing Yun Qing's unusual behavior and seeing his pale face, rushed forward, her eyes filled with worry.
Yun Qing could only wave his hand dismissively, forcing a weak smile to reassure him, "It's nothing, just a slight headache. Give me some time to recover!"
He then resumed his complete absorption in processing his memories.
Uchiha Mikoto's worry deepened upon hearing this, but she didn't disturb Yun Qing further. Instead, she reached out and gently massaged his temples.
Her massage seemed to work; she felt Yun Qing's pain lessen slightly, and his breathing became more even. She felt a surge of happiness, but it was quickly replaced by worry.
At this moment, Uchiha Yun Qing was rapidly processing his past life's memories. The scenes were so familiar; it was as if he were reliving his uneventful 25 years of his previous life, everything vividly clear in his mind.
It took him a while to recover, and he finally understood everything. He thought to himself, "I never expected to be reborn! The Naruto world? It really is a dangerous world!"
Especially since, in this life, he was still an average Uchiha.
Uchiha Yunqing was born in Konoha year 20, the same age as his childhood friend, Uchiha Mikoto.
He just turned 18 today, possessing the strength of a Special Jonin, a two-tomoe Sharingan, proficient in Fire Release, and with some knowledge of Lightning and Water Release techniques, as well as basic Uchiha-style swordsmanship.
He had short, bright silver hair, a tall and straight figure of 1.85 meters, and strikingly handsome features, like a handsome version of Kakashi. Even in the Uchiha clan, where handsome men and beautiful women abound, his looks were exceptionally striking.
He was an orphan, orphaned at a young age, and had little presence within his clan.
His parents died when he was three years old, during a mission while saving the elder.
Therefore, the Grand Elder had always taken good care of him, and he lived in the Grand Elder's house until he was 12 years old.
He and the Grand Elder's granddaughter, Uchiha Mikoto, were childhood sweethearts, growing up together, sharing similar interests and mutual affection.
The Grand Elder didn't initially object to their relationship, but as the clan's Grand Elder, he belonged to the hawkish faction and couldn't consider things so one-sidedly.
Especially since the current Uchiha clan head, Uchiha Munenori, intended to arrange a marriage between his son, Uchiha Fugaku, and Mikoto to win over the Grand Elder and his hawkish faction, successfully pushing Fugaku to succeed as clan head.
The Grand Elder was conflicted.
He wanted to support Yun Qing and Mikoto's relationship, not only because he admired their love but also out of gratitude.
However, he also had high hopes for Fugaku, who had earned a fearsome reputation during the recent Second Shinobi World War. He felt Fugaku was capable, seemed like a hawk, and should be a good clan leader.
Yun Qing wanted to be with Mikoto, but his strength was still lacking; he hadn't even awakened the three-tomoe Sharingan yet.
In the Uchiha clan, the Sharingan was a symbol of status. Even though Yun Qing, with his two tomoe, was a Jonin-level ninja, his status within the clan was only average.
Fugaku, on the other hand, was not only the clan leader's son and possessed the three-tomoe Sharingan, but he had also made numerous contributions in the recent Second Shinobi World War, gaining great fame and becoming the new leader of the clan.
Yun Qing had always felt a sense of crisis and resentment because of this.
Unexpectedly, today he awakened his past life memories and activated the daily login system.
It's like heaven is helping me!
As his past life memories awakened and merged, Yun Qing felt his soul power and spiritual power surge dramatically. His mind became much clearer and sharper, and his comprehension increased significantly.
At the same time, he felt his eyes begin to heat up and swell, his pupil power rapidly increasing.
The next moment, he couldn't help but open his eyes. Pairs of tomoe Sharingan suddenly appeared, the tomoe within them rapidly rotating around the center of their pupils, leaving afterimages.
Three breaths later, a third tomoe appeared in each eye, and the rotation slowly stopped.
"Eh? Yun Qing, you awakened three tomoe? That's wonderful!"
Noticing the anomaly, Uchiha Mikoto, who had turned and peeked over to witness this, immediately congratulated Uchiha Yun Qing with a joyful expression.
Meanwhile, she fantasized in her heart, "Great! Yunqing has awakened the three-tomoe Sharingan! Now, Grandpa shouldn't stop me from being with Yunqing, right? That annoying Fugaku can finally give up, right?"
"Haha! Yes, finally awakened the three-tomoe Sharingan!"
Uchiha Yunqing had no idea what Mikoto was thinking. Hearing her congratulations, he nodded happily.
Finally awakened the three-tomoe Sharingan!
This had almost become his obsession.
Feeling his eye power increase several times over, and his vision become several times clearer, he was filled with emotion.
He had tried for many years without success, but unexpectedly, awakening his past life memories brought such good fortune.
However, thinking about it, it was quite normal.
The awakening of the Sharingan is inherently related to soul power and spiritual power; emotional stimulation is merely a symptom.
Having awakened his past life memories and seemingly fully integrated his soul power from that life, resulting in a surge in both his soul and mental strength, this change was not surprising.
"System, introduce yourself!"
At this moment, Uchiha Yunqing remembered that he seemed to have activated and bound himself to a system, and couldn't help but ask expectantly in his mind.
[This system is a sign-in system. The host can sign in once in each different world to receive rewards.]
The system's cold, mechanical voice sounded in his mind again, and at the same time, some system-related information flooded into his mind.
Uchiha Yunqing quickly digested this information and immediately understood the system's functions.
To be honest, he was quite disappointed.
This system really can only allow one sign-in per world.
Plus, it has an Eye of Insight that can see all creatures and items, and a regular attribute panel—that's it.
"So, after signing in once in the Ninja World, this system is basically useless? Or are the Kamui Space and Kaguya's Yomotsu Hirasaka Space considered different worlds?"
Uchiha Yunqing, disappointed, couldn't help but ask the system.
It turned out he was overthinking it. In the system's view, the Kamui Space and similar areas belonged to the Ninja World and couldn't gain more sign-in attempts.
Bug exploit failed!
"Forget it, better than nothing. I'll sign in once and hope I get a powerful cheat code."
Thinking this, Uchiha Yunqing immediately chanted in his mind, "System, sign in!"
[Ding! Sign-in successful. Congratulations to the host for obtaining: Myriad Manifestations Body. Do you wish to fuse with it?]
[Myriad Manifestations Body (Can devour and be compatible with various human physiques, bloodlines, and power systems, extracting their advantages and eliminating their disadvantages, integrating them into one's own physique as characteristics, and continuously promoting the evolution of the physique)]
"Wow... this physique seems very strong!"
Uchiha Yunqing was overjoyed upon seeing this result and receiving the relevant information about the Myriad Manifestations Body.
While this physique couldn't directly and quickly enhance his strength,
it was entirely possible to acquire a Sage Body by absorbing and fusing Hashirama cells, Uzumaki bloodline limits, and the like. This would significantly boost his physique and chakra reserves, while also granting him the chance to awaken the Eternal Eye and even the Rinnegan.
Furthermore, he could even acquire other bloodline limits through absorption and fusion!
"Fuse!"
The next moment, he felt a warm current flow through his body, which quickly subsided.
He found that his energy seemed more abundant, but his chakra reserves hadn't yet shown a significant increase. He expected further development and fusion with other physiques and bloodline limits to achieve a more noticeable increase.
But that was enough.
"Prosperous..."
"Whoosh!!!"
Just as Uchiha Yunqing was about to express his feelings, a loud bang from the sky outside interrupted his thoughts.
At the same time, a grand, indifferent voice resounded in the minds of him and all intelligent life in the entire ninja world:
[The fusion of all realms, the portal to spacetime appears.]
[Intelligent life from all realms can travel to other worlds through the portal to spacetime, laying the foundation for the fusion of all realms. Please cherish this opportunity.]
