[Successfully fused Sasuke's power and obtained the Ninjutsu Chidori] [Successfully fused Naruto's power and obtained the ninjutsu shadow clone technique] [Successfully fused with Kakashi's power and gained a 50/50 ability] In front of those with super powers, Ye Jin is like the supreme god, sweeping everything in the apocalypse, opening up the road to invincibility, and respecting ninjutsu.
