I'm in the Dragon Clan, bound to the Naruto Counterattack System

Cheng Sui transmigrated to the Dragon Clan world. Just as he was about to graduate from Kassel College after four years, a system arrived. But what the heck was this Naruto Counterattack System? He was still classified as a perennial Chunin, an ordinary teacher at the Ninja Academy. [Uchiha Sasuke and Uzumaki Naruto are fighting again in class. The Third Hokage is currently watching this with a crystal ball. You need to use reasonable means to resolve this conflict.] [Mission Rewards: Third Hokage's favor, one-tomoe Sharingan, Uzumaki clan physique] Cheng Sui: "???" Looking at Chu Zihang and Caesar passionately slashing at each other, he fell into deep thought.

"System, is this the Tailed Beast you asked me to subdue?" (Single female lead Erii, no separation between Chu Xia and Kaino)
