Naruto: Sharingan Wholesale from the Start!

After transmigrating into the Hokage world, Tiandao Zongsi acquired a technology-focused System.

As time passed and technology advanced, the Byakugan became as cheap as cabbage because it was less useful than the Sharingan. The Sharingan was sold for the price of pork because it consumed too much chakra. Wood Release was everywhere, while Ice Release could only be used to make refrigerators...

Naruto Uzumaki: It's time to get a two-tomoe Sharingan.

Sasuke Uchiha: You foolish big brother, surprise! You can get the Mangekyo without going insane!

Sasori of the Red Sands: I get it now! Flesh is pain! Machines are ascension! Puppets? Even dogs wouldn't use them!
