After saying everything in one breath, Li Yu hurried away.
"I should get ready. I'm going to the Ninja Academy tomorrow."
"The teacher in charge of the team... Just thinking about it is interesting."
"Rookies, prepare to face judgment!"
Li Yu returned home and saw Uzuki Yuying sitting by the window, propping her adorable chin on her hand. A faint smile played on her lips as she gazed blankly outside.
She didn't even notice Li Yu, who had already come up beside her.
"Yuying, what are you thinking about?"
"Ah!" She turned around and saw Li Yu. Her face instantly flushed, and she lowered her head, not daring to meet his eyes.
Li Yu didn't think much of it. Seeing Uzuki Yuying like this, he bent down and swept her into a princess carry.
She cried out again, "Ah!" and buried her face in Li Yu's chest. Her cheeks burned.
Carrying Uzuki Yuying, Li Yu wore a mischievous smile and said nothing as he entered the room, opened a hidden door, and strode toward the laboratory.
Uzuki Yuying, nestled in his arms, didn't notice the change in their surroundings. She murmured, "I'm not feeling well today. Could we..."
When they reached the laboratory, he set Uzuki Yuying down in the middle of the carved formation and grinned. "Could we what?"
Uzuki Yuying looked around and realized what was happening. She was instantly mortified.
"Hahahaha! What were you thinking? Of course I know you're not feeling well."
Li Yu composed himself and said seriously, "I brought you here for your safety."
"I plan to seal a permanent Flying Raijin Mark on your arm. If you're ever in danger, I'll be able to reach you right away."
"A permanent Flying Raijin Mark? It's a new jutsu I developed."
"If you encounter a situation you can't handle, you can activate the mark. Even if I'm away from the village, I'll know you're in danger and can use the Flying Raijin to return in time."
"You can also draw on the large amount of chakra stored in the Flying Raijin Mark to use ninjutsu. You can even use the Flying Raijin Jutsu."
Li Yu gestured for Uzuki Yuying to sit. He lifted the Forehead Protector covering his left eye, revealing a blood-red eye with three Tomoe slowly turning in it.
Uzuki Yuying covered her mouth with both hands, staring at his eye in shock. Trembling, she stammered, "A S-Sharingan... The Uchiha Clan's Sharingan!"
"Yuying, don't overthink it. The shocking part is still coming."
Li Yu focused chakra into his eyes. His right eye transformed into a Sharingan with three Tomoe as well, while the three Tomoe in his left eye spun rapidly, turning into a four-pointed pinwheel.
"Could it be..."
"I'll explain that later." As he spoke, his hands quickly formed seals.
He gathered chakra into his five fingers and grasped Uzuki Yuying's right wrist with one hand.
"Flying Raijin—Seal!"
A black pattern resembling a three-pronged kunai appeared on her wrist, with a distinctive black spiral in the middle.
Li Yu let out a breath of relief.
"It worked."
"A sealing technique combining the Four Symbols Eight Trigrams Seal with the Flying Raijin Mark."
"Yuying, try infusing the mark with your chakra. Use it to sense the Flying Raijin coordinates."
Li Yu casually tossed out one of his Specialized Kunai.
A flash of purple light, and Uzuki Yuying caught the kunai in midair before landing lightly.
"Great! I didn't expect you to master the Flying Raijin Jutsu so quickly."
"Clap, clap." Li Yu applauded, his eyes shining. It was hard to tell whether he was praising Uzuki Yuying or congratulating himself on his new jutsu's success.
"Looks like we can move on to the second step."
The Mangekyō Sharingan in Li Yu's left eye spun rapidly. Space twisted, and three enormous scrolls appeared on the ground.
"Yuying, come over here!"
A flash of purple light, and she appeared beside Li Yu. Beaming, she said, "The Second Hokage's Flying Raijin Jutsu is incredible. It just consumes so much chakra."
"After using it twice just now, I've already used up nearly a tenth of my chakra."
"It looks like your chakra really is too limited to compare with mine."
"But don't worry. I've already thought of a solution."
He unrolled the scroll labeled One-Tail, then took Uzuki Yuying's marked wrist and indicated that she should sit beside him.
Li Yu gathered chakra into the five fingers of his left hand and placed them on the chakra scroll, twisting as if turning a knob.
He did the same with his other hand, twisting open the seal on Uzuki Yuying's hand in the same way.
"Creak, creak."
The One-Tail's chakra poured from Li Yu's arm into his body like floodwater bursting through a dam, then flowed into the seal on Uzuki Yuying's arm.
In the same way, Li Yu transferred half the chakra from the One-Tail, Four-Tails, and Five-Tails scrolls into the permanent Flying Raijin Mark on Uzuki Yuying's wrist.
Three small spiral patterns appeared on the mark. Li Yu wiped the sweat from his forehead and let out a relieved breath.
"Finally, it's done."
"Yuying, with the chakra of these three Tailed Beasts, you've become a Kage Level powerhouse—one of the strongest among them."
Li Yu put the scrolls away in the Kamui Dimension, covered his left eye with his Forehead Protector, and deactivated his Sharingan. Then he stood up, took Uzuki Yuying's hand, and activated the Flying Raijin.
Outside Konoha
Uzuki Yuying was thrilled. She used the method Li Yu had taught her to release the sealed chakra.
She placed her left hand on her right wrist. "Creak." The One-Tail's chakra surged from her arm into her body, whipping up sand all around her. She could actually control the sand.
"Creak."
"Creak."
Steam billowed from Uzuki Yuying's body, then she grew as hot as molten rock.
"You have Boil Release and Lava Release? I'm a little jealous."
After getting used to how her body felt, Uzuki Yuying bounced over to Li Yu, hooked her arm around his, and leaned against him.
"Yu, you're so good to me."
Li Yu turned to gaze deeply into Uzuki Yuying's eyes, then spoke like the leading man in a romantic drama.
"If I'm not good to you, who else could I be good to?"
In a romantic drama, the next step would be for them to sleep together.
Li Yu's gesture was like buying your girlfriend a house and a car in the modern world. Of course she'd be happy.
In this war-torn ninja world, strength mattered most.
With Kage Level strength, even if she ran into Beyond Kage Level Madara, she could hold out for a few rounds instead of being casually killed like an ordinary ninja.
After using the Flying Raijin to return to the laboratory, Li Yu explained to Uzuki Yuying where his Sharingan had come from.
He told her, more or less, how he'd been seriously injured by an enemy's Explosive Tag trap on the battlefield, how he and Orochimaru had conducted research, and how the results had allowed him to recover and awaken Wood Release and the Sharingan.
In short, he'd turned misfortune into fortune.
