Nicely done, you are a quick learner. You just learned:
Now, This Next Jutsu is another type of summoning. Like before, you will summon an Split Eel. This Eel will need to be large enough to swallow you whole with ease. Once the Eel Swallows you, it will disperse into countless smaller Eels that will cover a water source. You can then exit any of the smaller Eels at your desired location and have the remaining Eels attack your opponent. Keep in Mind, Just like the Eel Hiding Method. Doujutsu and Sensors will be able to know your location. I will show you an example on how this works..
Hei quickly Slams his hands together summoning an Eel that erupts from the water under him with it's mouth wide open. This Eel swallows Hei with ease as it disperses into hundreds of smaller Eels that swim in a swarm that covers a Long Range area around the battlefield. Hei then emerges Long Range behind you out of a small Eel. The remaining Eels converge on your location to attack in a Feeding frenzy, however just before they reach you they Poof. Hei then walks back to your location
You see this can be used to both Evade/Escape and opponent and attack at the same time.
