Uchiha: Isn't This Better Than the Sharingan?

Good news: He traveled through time and became the leader of the Uchiha clan. Bad news: Tomorrow is the night of genocide, and the filial son's knife has been sharpened. What's even more outrageous is that this broken system actually engages in "bloodline exclusion". Geniuses will explode at the first touch, and only losers can connect 100%! This cheat turned out to be a big trouble, and I had no choice but to go to the bottom floor to collect the "garbage" despite being scolded. High-level training in progress... The genius Itachi showed off his ancestral shuriken, and he formed a seal like flying. (Raises eyebrow) I smashed the target with a backhand shot, and the ninjutsu he was proud of was completely destroyed. The great elder's outlook was shattered. ANBU encirclement and suppression night... Danzo sent a root assassination, and the elite ninja spit out a B-level fireball. The good-for-nothing Tiehuo took out his RPG and shot it into the soul with flames soaring into the sky. The roots were directly fried into pieces of meat. Danzo collapsed: "No, why can't he even open his Sharingan?!" From then on, the seals were completely insulated from Uchiha, and the entire ninja world suffered from a phobia of insufficient firepower!
