Yeah he just conquered China in two panels, no big.
Sometimes a timeskip skims over unimportant stuff, and then there's this.
There's a manga out there, i forgot the name, but it had pretty shitty art, and in there Nobunaga conquers the whole world in like 10 chapters and then develops his own space program to conquer the entire galaxy
This one however is a good runner up for best Nobunaga dick rider out there, like damn the author is working that rod like you wont believe it, it is doing all the motions up down, side to side, circles, back and forth, twerking that ass for Nobunaga
