Idea of a cool addition to Jhin's ulti.

What if, On the last ult of Jhin, The one which does 250% damage. How about if it was able to keep going if it killed the target? Example On 20% HP, Gets hit by Jhin's final bullet, Bullet continues to go on a straight line and is able to hit another champion from there, if it kills the next champion it continues ect ect. Of course- It wouldn't increase the bullets range or anything but it would just be a really neat mechanic imo.
