As the chakra continuously flowed back into the Divine Tree, the chakra fruit symbolizing life and power became increasingly mature, and its quality was also gradually improving.
Along with more and more people's chakra being completely devoured, the Divine Tree roots covering the world were also gradually withdrawn under Ryun's control.
Although Ryun coveted the Divine Tree's power, he had to admit the Divine Tree posed an astonishing hazard to the natural ecosystem.
The Ninja World was his home. He would not allow the Divine Tree to absorb this planet's energy again. After the Divine Tree nurtured this final chakra fruit, Ryun would place upon it an eternal shackle it could not break free from.
The chakra propagated for a thousand years had already reached a very astonishing quantity. Therefore, the Divine Tree nurturing this chakra fruit would not affect the natural environment, because the chakra within humans was already sufficient to support the fruit until maturity.
"Dad, Grandma and Mom are calling you home for dinner."
Ryun was originally concentrating on 'liberating' all humanity, but his daughter came to the base of the Divine Tree to call him home for dinner.
"Let's go, let's go." Ryun instantly appeared before Nanaise, then took her and teleported inside the Shadow Mansion.
Although he wasn't hungry, since Asuka was home, he wouldn't miss lunch or dinner.
After a sumptuous lunch, the family drank afternoon tea together and played Dou Dizhu.
This was one of Asuka's old hobbies. It must be said, the Senju clan's genes indeed contained a bit of a gambling component.
"Lord Ryun, some strange creatures have appeared outside the Shadow Mansion. They are clamoring to see you. One of them even said it is your brother."
A female Jonin wielding the Long Sword, Nuibari, loudly reported from outside the room.
"Please bring them to the garden. I will be right there."
"Also, go and fetch Tsunade later. Tell her my mother is looking for her to play cards." Ryun intended to find a plump, lucrative 'big fat sheep' for Asuka.
Tsunade was currently staying in Otogakure. Whether she could provide economic value to Asuka was unimportant, but she could certainly provide a full dose of emotional value.
"Yes."
A moment later.
In the Shadow Mansion garden, Ryun met a black-clothed man with a haughty expression and two sharp dragon horns on his forehead.
To the left of the man crouched a toad, and to the right lay a slug. Such a lineup was indeed why the female Jonin called them strange creatures.
"Hmph. Some people are all grown up now, forgetting the brothers who suffered together."
As soon as Ryun appeared, the black-clothed man looked down his nose at him, delivering a strong warning.
This scene made the toad and slug behind him break out in a cold sweat. They never expected this black dragon to be so audacious, daring to speak arrogantly to anyone, even having the nerve to issue a warning when meeting the master of the demon tree.
Ryun's face was expressionless, seeming somewhat displeased. He walked straight up to the Black Dragon, then directly extended his fist towards him.
"Hmph, childish fellow."
The Black Dragon snorted coldly again, raised its own fist, and fiercely punched back.
Boom.
Fist met fist with a loud sound. The moment the punches connected, the next moment, to the toad and slug's astonishment, the two actively embraced each other.
The tense atmosphere instantly vanished. Joyful smiles appeared on both their faces.
"Good brother, long time no see. I have missed you dearly."
Ryun smiled and patted his back, making the Black Dragon cough incessantly.
"Cough, cough. You don't need my help anymore now. I haven't eaten a ninja in so long." The Black Dragon said with a resentful look.
"Although human flesh and blood contain powerful energy, in the end, it is still filthy stuff. Lord Black Dragon should really eat less of it." Ryun admonished earnestly.
"Filthy stuff? Devouring the precious bodies of humans clearly aids the strengthening of qi and blood. Sage power also increases somewhat." The Black Dragon frowned and retorted.
"Your qi and blood are enhanced, but don't you feel the Sage Dao, natural energy, is harder to comprehend? Your Sage power has increased, but quantity does not equal quality. What you think is enhancement might be a form of weakening in disguise."
Back in Loulan, Ryun had eaten some half-raw meat. That food was indeed very filling and contained more energy, but eating raw meat did affect Sage Art cultivation. Because he was in a geomantic treasure site like the Dragon Vein, he could perceive these subtle changes happening at the time.
Of course, a Jiao Dragon is definitely different from a human. Its daily diet is certainly mainly flesh and blood. Ryun said all this purely to scare it, to make it eat fewer humans. After all, this Old Black was quite easy to fool.
As soon as this argument was made, the Black Dragon's eyes widened in shock.
A brief silence fell over the Shadow Mansion garden.
The Slug Sage's face showed no emotional change, but the Toad Sage's face displayed obvious astonishment.
An evil dragon and a human discussing the topic of eating humans. The key point was that this topic did not provoke dissatisfaction from the human. The human, the supreme powerhouse, even remained calm and composed.
This scene seemed rather discordant. Although the reasoning was worth pondering, the topic itself was bloody.
"You are right. My cultivation was indeed affected after I ate humans, especially while maintaining human form. At that time, I felt the heavens and earth were unclear, my spiritual platform was clouded, and desires gradually rose along with emotional agitation."
Hearing this, Ryun smiled and nodded.
"So, you should eat fewer humans in the future, so your cultivation isn't ruined. Over these years, the power within you has increased many times over. Had I known earlier, I should have summoned you to assist in battle."
The Black Dragon's strength growth was very rapid, completely exceeding Ryun's expectations.
Originally, he thought this Jiao Dragon was only at tailed beast level. Even if summoned, its presence would be negligible. That's why he hadn't summoned it for many years. But now, after a close perception, he realized he had somewhat underestimated the dragon.
"Who do you think I am? These years, I have not neglected my cultivation. Now I am the most powerful being in Ryuchi Cave." The Black Dragon said with a face full of pride.
The potency of the dragon bloodline was undeniable. Its cultivation speed far surpassed that of most living beings. As long as it put in the effort, a fierce beast like a Jiao Dragon could often cultivate to the level of a great demon, its combat power far exceeding opponents of the same rank.
"Good, good. As long as you haven't become a useless creature. In the future, I'll take you to play beyond this planet, let you taste the Otsutsuki clan." Ryun said with a gratified expression, patting its shoulder.
"How are you talking? Giving you face, are you? Don't think just because you control that demon tree you can be insolent before me."
As soon as the Black Dragon's words fell, its eyes quietly transformed into the Rinnegan form. It found it couldn't move.
"Old Black, you are as weak as a little loach."
