Arc 7Thunder on the Frontlines
Fang Xu studied sealing and fought on the Eastern and Hidden Cloud fronts while Minato held off A and Killer B. During a brief exchange in another world, Fang Xu gained powerful Haki, swordsmanship, and Devil Fruit abilities, then left the arc facing the Third Raikage alone.
- Minato returned with complete sealing manuals and Flying Thunder God notes, while Sakumo warned Fang Xu and Kakashi that Kirigakure was massing on the Eastern Front.
- The Third Mizukage launched a surprise assault, but Fang Xu killed eight Kirigakure jonin and the Three-Tails Jinchuriki before his Railguns broke the enemy formation and forced a retreat.
- Hiruzen Sarutobi redeployed Sakumo and Fang Xu to the Land of Rivers, where Minato used Flying Thunder God to repel A and decimate Hidden Cloud's pursuing troops.
- Sakumo and Fang Xu left shadow clones on the Eastern Front and traveled toward Minato, while Fang Xu exchanged swordsmanship insights in the One Piece World and received powerful Haki and Devil Fruit abilities.
- Fang Xu tested his new powers, discovered that the Dark-Dark Fruit could extract and transfer bloodline abilities, and assigned shadow clones to develop his techniques and study Flying Thunder God seals.
- When Killer B launched a Tailed Beast Ball at Konoha's camp, Fang Xu arrived with Sakumo and destroyed it with a Railgun.
- Fang Xu wounded and knocked out A, prompting Blue B and Killer B to withdraw as Konoha's forces reclaimed their defensive lines.
- The Third Raikage arrived and blocked Fang Xu's Railgun with Hell Stab: Four-Finger Nukite, while Fang Xu ordered Konoha's forces to hold position and faced him alone.
