Ch. 401Expansion Jutsu
Chapter Summary: “Expansion Jutsu”
Key Plot Points and Events
- Yizhe reflects on the difference between ordinary medical ninjutsu and Yang-Attribute Chakra. Standard healing techniques merely stimulate cells to promote regeneration, while Yang-Attribute Chakra directly influences and transforms life itself.
- He considers the enormous potential of applying Yang-Attribute Chakra to medical ninjutsu, believing it could heal injuries that conventional techniques cannot. However, Yin-Yang Chakra transformations are extremely difficult to master and are guarded as secret techniques.
- Yizhe doubts Tsunade’s belief that Yang-Attribute medical ninjutsu could have saved people from her past. He suspects that her temperament and lack of aptitude for chakra nature transformation might have prevented her from mastering such techniques anyway.
- The chapter shifts to Yizhe’s examination battle against Akidō Ryūno. Ryūno uses the Expansion Jutsu, growing into a massive giant with greatly increased strength.
- Ryūno smashes the ground with his huge palms and then performs Mountain-Crushing Collapse, launching his enormous body downward with devastating force.
- Yizhe avoids confronting the attack directly. Although he could potentially block it with Eight Trigrams Palms Revolving Heaven, doing so would leave him immobile and vulnerable afterward. He is also restricting himself to the Byakugan and Gentle Fist, refusing to use Monstrous Strength.
- Ryūno’s attack creates a huge crater, impressing the spectators. However, the crowd’s praise turns into an insult when someone calls him “fatty,” angering him because of the Akimichi clan’s sensitivity about their weight.
- Yizhe identifies Ryūno’s large size as a weakness and prepares a counterattack. Ryūno unexpectedly cancels the Expansion Jutsu, instantly shrinking back to normal size and avoiding Yizhe’s flying knee.
- Yizhe realizes he had underestimated Ryūno and must now account for the opponent’s ability to rapidly deactivate the technique.
Character Developments
- Yizhe: Demonstrates tactical restraint and careful analysis. Rather than relying on overwhelming strength, he limits himself to the Byakugan and Gentle Fist, prioritizing mobility and strategic positioning. He also gains a more nuanced understanding of Ryūno’s abilities.
- Akidō Ryūno: Shows tremendous destructive power through the Expansion Jutsu, but also reveals unexpected combat awareness by ending the technique at the right moment to evade Yizhe’s counterattack. His sensitivity to being called “fatty” highlights his personal vulnerability.
- Tsunade: Though absent from the fight, she is characterized through Yizhe’s skeptical thoughts. Her regret over not possessing Yang-Attribute medical ninjutsu suggests emotional pain connected to people she failed to save, while Yizhe questions whether she could realistically have mastered the technique.
Significant Themes
- Limits of medical ninjutsu: The chapter contrasts cellular stimulation with true life-manipulating power, emphasizing the vast difference between conventional healing and Yang-Attribute Chakra.
- Knowledge as a guarded power: Yin-Yang Chakra techniques are portrayed as rare, secret, and difficult to develop without proper instruction.
- Strategy over brute force: Yizhe avoids matching Ryūno’s strength directly and instead exploits the limitations of his enlarged form.
- Strength and vulnerability: Ryūno’s immense physical power comes with reduced mobility and a larger target, while his emotional reaction to the crowd reveals that physical dominance does not eliminate personal insecurity.
- Adaptation and underestimation: Both fighters adjust to each other’s techniques, and Yizhe is forced to revise his assumptions about Ryūno.
Character Interactions
- Yizhe vs. Ryūno: Their battle centers on the contrast between speed and precision versus size and destructive force. Yizhe dodges Ryūno’s attacks and studies his weaknesses, while Ryūno surprises him by canceling the Expansion Jutsu and evading the counterattack.
- Ryūno and the spectators: The crowd admires his destructive attack but inadvertently insults him by calling him “fatty,” exposing the tension between public admiration and personal sensitivity.
- Yizhe and Tsunade: Their relationship is presented indirectly through Yizhe’s critical evaluation of her medical theories, regrets, and ability to master Yang-Attribute Chakra.
