Warring States Uchiha: My System Short-Circuited

Transmigrate to the Warring States period and become Uchiha Madara's cousin. The night of the clan's massacre is still… No, the Warring States period is the real hell. First, Asura and Indra are locked in a deadly rivalry; then there's Black Zetsu's thousand-year scheme. To survive this family feud among the Otsutsuki, Uchiha Yang was just thinking he'd have to fight for his life when... "Wait, did this System get something wrong?" Uchiha Yang jumped in surprise as he read the System's notification. [Survive the battle against Edo Tensei Madara.] [Reward: 50% more chakra and the Two-Tomoe Sharingan.] Uchiha Yang stood with his hands on his hips, staring at the twelve-year-old brat Madara in the distance, and fell silent. [System notification: Kill the [Elite Jonin], the Konoha rogue Senju, to obtain half of their chakra.] Uchiha Yang looked at the Genin lying on the ground and didn't know what to say. "Wait, you call refining chakra absorbing natural energy?!" "And you want me to defeat Otsutsuki Toneri? This is the Warring States period!" "Capture the Nine-Tails alive and be rewarded with Nine-Tails chakra!" Uchiha Yang stared at the ordinary fox in his arms, the one with only a single tail, and was completely speechless.
