Tsunade, Perfect Shikkotsu Forest Sage Mode
Uchiha Kō released the Uzumaki Menma, Heavenly Dao naturally sensed it. His expression darkened; he hadn't expected Uchiha Kō to be so calm, which was definitely not a good thing for him.
Now that Uzumaki Menma has realized what's happening, she's naturally unwilling to serve him anymore. In other words, he has one less piece he can control.
He could only remain silent while continuing what he was doing. Only when this was accomplished would he have a chance to defeat Uchiha Kō again.
Shikkotsu Forest
With the departure of the Uzumaki Menma, Shikkotsu Forest returned to its former tranquility. Sunlight streamed through the clouds, illuminating the once somewhat eerie sacred Shikkotsu Forest with dazzling brilliance.
The Katsuyu Sage wriggled its body and came to Uchiha Kō's side, a slimy little hand extending from its chest and reaching towards Uchiha Kō.
Uchiha Kō was taken aback at first, then he understood. He extended his hand and shook hands with the only sage of the Shikkotsu Forest, the Katsuyu Sage.
Katsuyu Sage's feelings were very complicated. If he had known that Uchiha Kō was so powerful now, he should have defeated the people of Ryūchi Cave and Mount Myoboku back then, forcibly converted Uchiha Kō, and made him the successor of their Shikkotsu Forest Sage Mode.
Even the Katsuyu Sage couldn't imagine how powerful the White Snake Sage of Ryūchi Cave was now. His successor had grown to such an extent that he could even contend with the representative of Heavenly Dao!
"Uchiha Kō, would you be willing..." After thinking for a moment, the Katsuyu Sage sighed and swallowed his words. Now that the other party had inherited the lineage of Ryūchi Cave, it was too late.
Uchiha Kō chuckled, "Katsuyu Sage, I think you're being too focused on me. Instead of looking at me, you should look at my wife, Tsunade."
Tsunade was initially quite proud of her husband, who single-handedly defeated one of the representatives of the Heavenly Dao and even crossed time and space to fight for her. Her heart was already warmed by his bravery.
She was already content watching the Katsuyu Sage chat with her husband, but then Uchiha Kō called her name. She was a little confused. "Husband, me?"
Tsunade raised her delicate, white hand and pointed to herself, her eyes filled with confusion and bewilderment. Why had Uchiha Kō and the Katsuyu Sage's conversation somehow turned to her?
However, Tsunade obediently walked forward and came to Uchiha Kō's side. Uchiha Kō put his arm around Tsunade's shoulder and looked at the Katsuyu Sage with a smile.
The Katsuyu Sage shook his head. "Uchiha Kō, I tried it before. Although Tsunade has good talent, her physique and willpower are not enough to pass the test of Shikkotsu Forest." The Katsuyu Sage sighed.
More than twenty years ago, when she saw Tsunade arrive at Shikkotsu Forest, she sensed Hashirama's aura from her. To be honest, she was very excited because after Hashirama's death, no ninja in Shikkotsu Forest had been able to learn Sage Mode.
Some exceptionally talented individuals, lacking the necessary patience and perseverance, were too eager for quick success and were ultimately fused into her body. Others were hardworking ninjas who devoted all their efforts to mastering Sage Mode, but lacked the necessary aptitude and failed to learn it within the allotted time, and were also eventually melted away.
The Shikkotsu Forest Katsuyu Sage had already prepared for the possibility that there would be no successor in Shikkotsu Forest for a hundred years. However, when the three families went to find Uchiha Kō at the same time, everyone was convinced that Uchiha Kō could learn any of the Senjutsu from any of the families.
In the end, Ryūchi Cave was chosen. The Katsuyu Sage chose not to compete for it and even sided with Ryūchi Cave because Shikkotsu Forest and Mount Myoboku had already produced successors, while Ryūchi Cave was still single.
Therefore, they decided to give the White Snake Sage face. After all, the Three Great Sage Regions are outwardly competing with each other, but in reality, they are all in cahoots. If one of them is in trouble, the other two will definitely not stand idly by.
Unexpectedly, this concession directly caused Shikkotsu Forest and Mount Myoboku to drop in the rankings, while Ryūchi Ryūchi Cave remained firmly in first place for over forty years. Now, Uchiha Kō has easily defeated the representative of the Heavenly Dao, making the Katsuyu Sage so jealous that his whole body turned purple.
Upon hearing the Katsuyu Sage's words, Tsunade twitched, her expression somewhat disappointed. She already knew about this. Looking at Uchiha Kō, she sighed, thinking that her husband must have wanted to help her obtain Sage Mode. Ignorance was no excuse.
Uchiha Kō shook his head and said, "Katsuyu Sage, the past is the past, and the present is the present. Now my wife has awakened her Sage Body and consumed the Ōtsutsuki Clan's Chakra Pellet, resulting in a significant improvement in both her strength and talent."
"Besides, there's a saying: 'One should look at someone with new eyes after just one day of recognition.' If you don't believe me Katsuyu Sage, you can try my wife's talent and physique." Uchiha Kō stared intently at Katsuyu Sage.
Upon hearing this, the Katsuyu Sage shuddered. "That's right!" she thought. "If you always look at others with the same old perspective, it only shows that you are short-sighted. Now that Uchiha Kō, the Lord of Humanity, has spoken, she naturally has to give him some face."
The Katsuyu Sage nodded, then merged Tsunade into his body, tested her physical strength and talent, and then his eyes lit up. He began to circulate the Sage Mode Senjutsu Chakra in Shikkotsu Forest, carrying Tsunade 'Chakra within him.
Tsunade was initially confused, but Uchiha Kō Biography told her, "Wife, close your eyes, carefully feel the flow of Chakra, grasp the pattern, memorize it, and then begin to circulate it."
"As for your concern about whether your body will melt, don't worry at all. Leave it to me, I'll keep an eye on it for you." Uchiha Kō's voice was calm and gentle, giving Tsunade a strong sense of security.
Tsunade smiled, closed her eyes, and immersed herself in the extraction and circulation of Senjutsu Chakra in Shikkotsu Forest Sage Mode.
Uchiha Kō sat cross-legged in meditation. He created a clone to observe Tsunade's condition, intending to wake her up if she was in any danger so he could familiarize himself with the human race's fortune and the power of the Lord of Humanity.
He had been in too much of a rush, constantly traveling Three Great Sage Regions, without time to rest or comprehend his newfound knowledge. Now that things had temporarily come to a halt, he was able to familiarize himself with his own power.
If a person is not even familiar with their own strength, but only possesses power, they will have to pay a price if they encounter a truly strong opponent in the future.
Uchiha Kō calmed his mind, sat cross-legged, and began to recall the events of the battle at Ryūchi Cave, one by one, one by one, one by one, as well as the feelings of gaining humanity and the use of human destiny.
Tsunade lay inside the Katsuyu Sage's body, feeling the Katsuyu Sage repeatedly demonstrating the operation of the Shikkotsu Forest Sage Mode and her understanding and absorption of Katsuyu Sage Senjutsu Chakra.
Tsunade is now completely absorbed in it. If it were the 15 or 16-year-old Tsunade from back then, she might not only be unable to understand the essence of Senjutsu Chakra, but she might not even be able to sense the circulation path of Sage Chakra.
Now, after being developed by Uchiha Kō and absorbing the Chakra Pellet, her talent is no less than that of Naruto and Namikaze Minato from the original work.
His understanding of the Shikkotsu Forest Senjutsu progressed from initial awkwardness to eventual mastery, even to the point of actively activating them.
Time flies, and a month has passed in the blink of an eye.
At this moment, Uchiha Kō opened his eyes, looked at Tsunade inside the Katsuyu Sage Body, a smile playing on his lips, and thought to himself, "It's done!"
The next moment, Uchiha Kō stood up and retracted his clone into his body.
Suddenly, Tsunade opened her tightly closed eyes and slowly stepped out of the Katsuyu Sage's body. With a gurgling sound, Tsunade detached from the Katsuyu Sage, her body covered in slime.
Tsunade frowned almost imperceptibly, then circulated her Chakra. In less than two seconds, her entire demeanor changed, a green Sage mask appeared, and she simultaneously shook off all the slime on her body.
Tsunade, Perfect Sage Mode mastery!
Uchiha Kō looked at Tsunade's green pupils and her unique sage-like face, and a smile appeared on his lips. Even the Katsuyu Sage couldn't help but nod. After many years, Shikkotsu Forest had finally produced a successor once again.
Shikkotsu Forest's Perfect Sage Mode has reappeared. Based on Tsunade's Perfect Sage Mode and her relationship with Uchiha Kō, she felt that Shikkotsu Forest's position could be moved up a notch.
Uchiha Kō chuckled, "Congratulations, my dear wife, on mastering the Perfect Sage Mode! From now on, you can extract Natural Chakra from the air for your own use."
Tsunade curled into a smile, then she deactivated Sage Mode and threw herself into Uchiha Kō's arms. "It's all thanks to my husband! If it weren't for you, how would the Katsuyu Sage have thought of testing my talent again? I wouldn't have gotten this second chance to learn Senjutsu."
Uchiha Kō scratched the back of his head, a smirk playing on his lips. The Katsuyu Sage looked at the two with a touch of envy, but she quickly realized that she was just a Katsuyu Sage, genderless, so what was there to envy?
Immediately, the Katsuyu Sage rolled his eyes and said, "Uchiha Kō, now that your wife has mastered the Shikkotsu Forest Sage Mode and the Shikkotsu Forest Sage Chakra, hurry back to the Ninja World."
"You've been gone for so long, the Ninja World might have changed a lot. You should go back and take a look, otherwise things might get messy during the final battle," the Katsuyu Sage said calmly.
What she said is not wrong. Now, Uchiha Kō is the ruler of humanity and the emperor of the entire Ninja World. If the human race is not united, or if war breaks out among the human race, it will lead to a sharp decline in population.
Then Uchiha Kō will definitely be the first to be implicated, which will be detrimental to the future battle!
Uchiha Kō nodded, then took Tsunade's hand and said to the Katsuyu Sage, "Thank you for the reminder, Katsuyu Sage. I also appreciate the kindness you showed my wife with your teachings. I, Uchiha Kō, will accept this debt of Uchiha Kō. If, in the future, you ever need my Uchiha Kō, I will not hesitate to help."
