At night, Kairen and Tsunade both slipped into a single room.
Kairen slowly walked to the window in silence, looking at the sky replaced by the dark curtain. From time to time, one or two stars fell into the Milky Way, piercing into the darkness.
The sky filled with stars—both beautiful and frightening.
A quiet voice drifted through the night:
"Wall-Facer Tsunade, I am your Wall-Breaker."
...
The next day, the weather was sunny, suitable for driving cattle and plowing fields.
Golden rays of sunlight slanted through the window, falling across the beauty's golden hair.
Tsunade's breathing was steady, the blanket pulled up to her shoulders, revealing skin, her head resting on Kairen's chest like a sleeping beauty.
Tsunade opened her eyes:
"You scoundrel!"
She slapped away Kairen's misbehaving hand, then wrapped both arms around his neck, snuggling against him like a little woman.
She whispered:
"You little rascal, my whole life will be ruined in your hands!"
Kairen kissed her gently:
"Isn't being ruined in my hands even better? I'll let you feel pleasure you've never known before."
Tsunade lightly bit his muscle, a faint affection appearing in her eyes, then that affection was replaced by rationality.
A trace of bitter smile appeared on her face as she spoke softly:
"Don't let anyone else see this."
Kairen froze and turned to look at Tsunade:
"Why?!"
Tsunade's head leaned slightly against his neck, her enticing fragrance slowly spreading.
"I don't want to ruin you. You still have a long, bright future to choose someone young and beautiful."
Kairen hugged her tightly. He understood what this woman was thinking, but in the future, this would never remain a secret underground romance. When he rules over the entire Shinobi World, whoever dares talk too much—he will annihilate their whole family.
The two leaned against each other for a while before Tsunade let go of his neck.
"Get up, we still need breakfast!"
"Got it!"
"Go to work already!"
Tsunade suddenly shoved Kairen away, put on her clothes, and went to the washroom to clean up.
Kairen left Tsunade's room and returned to his own bedroom.
Wolon and Fenchu, the two panda babies, were lying on the bed with a small blanket covering them.
Looks like Kairen didn't use them as pillows or cuddle toys last night. They had a wonderful night.
Kairen rubbed their little panda butts and lifted the two of them up.
"Hmm~"
Wolon and Fenchu let out a long yawn, rubbed their sleepy panda eyes with their paws, then looked at Kairen in confusion.
Kairen placed pen and paper in front of them:
"Did you finish your homework yesterday?!"
"Hmm~"
Wolon used its paw to write scrawls like a dog scribbling, and its face turned bitter—because it only learned "one, two, three," those three characters.
Fenchu was the same. The two panda babies knelt and begged non-stop, panda incense bowing.
Kairen lifted the two chubby pandas again, vigorously rubbing their fluffy fur:
"No bottle milk today!"
"Hmm!!"
Wolon and Fenchu instantly turned gloomy gray.
After they had a real breakfast, Tsunade went to the Hokage Building to work. The Chunin Exams were approaching, and Tsunade would only get busier—with no time to spend with Kairen.
Kairen stretched lazily, then transformed into a giant hawk and flew out of his villa.
Soaring hundreds of meters above ground, he felt exhilarated, massive chakra circulating.
"Multiple Shadow Clone Technique!"
"Bang! Bang! Bang! Bang!..."
Puffs of white smoke exploded in the air. In the blink of an eye, over a hundred shadow clones appeared out of thin air in the sky.
"Damn!"
"What the—!"
"Holy—!"
Gravity struck. The clones quickly sprouted wings to stabilize themselves.
Kairen returned to normal form and waved his hand:
"Keep working!"
The clones flew toward a training ground, while Kairen transformed into a fish.
With a splash, he dove into the lake, swimming freely and happily.
He didn't know how long passed before a system notification sounded.
Ding!
"Shadow Clone Snake Doctor has successfully developed a Wood Release Chakra Battery!"
Wood Release Chakra Battery—just the literal meaning alone explained it. A tool to replenish chakra.
Kairen shot up from the water, transformed into a hawk, and flew toward the training ground.
Snake Doctor and Academic Genius were surrounded by machines, holding a green jelly-like object filled with highly pure energy.
Kairen descended from the sky, staring at the green jelly in Snake Doctor's hand:
"This is the chakra battery? What does it do?!"
Snake Doctor explained:
"It replenishes a ninja's chakra like a Soldier Pill, but far better."
"It's composed of high-purity Wood Release chakra. It can instantly release a large amount of chakra throughout the body."
Kairen took the chakra battery, feeling its vibrant life force, stored long-term.
He bit into it.
The chakra turned into energy inside him, providing quite a lot of chakra—at least Chunin level.
"Main body, I'll give you the production method!"
Snake Doctor transmitted a stream of information into him. After absorbing it, Kairen mastered how to make the chakra battery.
Then he formed seals. Senju Clan Sage Body activated, massive chakra swirling like a vortex.
Kairen clapped his hands:
"Wood Release: Chakra Battery!"
In an instant, countless Wood Release jelly batteries appeared from the sky, dropping beside the clones.
With these chakra batteries, the clones no longer needed him to replenish their chakra—they could be even better corporate slaves.
Kairen looked around again, and in the direction of Revolutionary Kairen and Gunner Kairen, he saw something that looked like a rocket launcher.
He rushed over to watch them test the rocket launcher's power.
A clone carried the rocket launcher on its shoulder and pressed the button in front.
With a whoosh, the rocket shot out, turning into a streak of light. In the next instant, it blew a wooden dummy to pieces with ease.
Ding!
"Shadow Clone has successfully developed the rocket launcher!"
