The Eight-Tailed Beast was sealed in the lake around the Cloud Village. It was one of the most certain locations but still, nobody was able to find it. Because this lake had a unique constitution preventing anyone to look for it.
When I flew to the lake there were two other Akatsuki members were pondering over something. One of them was Deidara I fought earlier, and the other one was a strange man with a mask. His pupils were cyan, and white of the eyes was red. He was Kakuzu, same as he was in the original series, and had mastery over five elements.
In a sense, Kakuzu was immortal as well as Hidan, and they were a pair in Original series. Kakuzu was an angry man, with a problem to control his anger, and could kill even his partners when he was mad. Thus paired with Hidan, he wasn't able to kill later, allowing them to be the perfect couple.
Kakuzu was able to steal his enemies hearts and keep them in this body. This also allowed him to use the dominant Chakra Element of the owner of the heart. Kakuzu was as old as First Hokage, but because he was able to change his heart as he wished, he could switch the old heart with the young so he could live forever.
He also could separate the hearts to let them fight freely. He was the perfect candidate to look for this lake because he could spare a few lives to do a few experiments on the lake.
The lake was flashing with electricity that yellow in the color. This lake had a natural electricity source deep inside of it. They were very strong on top of it. If normal Ninja were to even touch it, Ninja would die within seconds. But Kakuzu could separate the heart with lightning affinity to dive in the lake. At least this was my idea.
Probably the heart puppets Kakuzu use wouldn't be able to find the seal inside the lake, thus making it useless to send it alone. But if Kakuzu were to dive with his actual body, he would get hurt. Even me with my %100 Lightning resistance, I would be injured with the electricity inside the lake, but I had other means, making it easy for me to take away the Eight-Tailed Beast.
If it were to be easy to dive in the lake, Third Raikage would do it when he was still alive giving the fact that Cloud Village knew this location for a long time. In original series, Third Raikage was able to fight against Eight-Tailed beast by himself and injured the other party on top of that. He was strong enough to fight against an army of 10.000 men and died from exhaustion, not by the attacks of the enemy. In all his life, he was injured once, and he injured himself, when he was about to pass out.

Third Raikage had strong Lightning Affinity and could shield his body via Lightning Barrier. Even that man wasn't able to dive in this lake to take out Eight-Tailed Beast. There was no one else could do it. The reason why I thought Kakuzu's heart puppet could dive in the lake was that it wasn't any life form but something similar to that of a rag-doll.
I closed to the Duo and attacked them from behind, and let out the Jon. Its been almost two weeks since I came here, yet I didn't let Jon out yet. Jon jumped out and attacked to Kakuzu while I killed Deidara with a single attack. She had a nasty self-sacrificing attack could be troublesome, so I didn't want to give her the chance.
Jon, on the other hand, cut Kakuzu into pieces and devoured all five hearts, before returning to my shoulders, and exclaimed angrily, "Bastard! Its been few weeks, how come you never let me out?" His cute, angry voice was adorable, still seeing him like this was making me sad.
"Yes, yes. I am sorry. I didn't forget about you, but it wasn't time for you to come out." I said with a sad face. I knew what Jon went through when he first created. His useless previous master also creator died and let Jon live in darkness for a very long time. Still, I couldn't let him out all the time, even though he wasn't fighting, because I might need him anytime.
"You better not do it again," he said while biting my ear.
"Right. How was the hearts? Can you master the elements?" I asked Jon. I used Hephaestus' Anvil to create another energy sea for Jon. This time I used all my SC to do it, but it was worth it. With the help of the Kakuzu's hearts, he could learn all the five elements in a short span of time.
"I can master them in a few months. Shouldn't take longer than a year." Jon said with the smirk.
"Good. Are you ready for the other thing?" I asked.
"Yes. It is all going according to plan," he said before vanishing in the Pendant.
I looked at the lake in front of me and covered my right hand with my Lighting Chakra. I put my hand to water to see how it would affect me, and it was as I expected earlier. My hand started to hurt and injuries started to form. I used Zhengi to cover my hand, and after I add a little bit of Nen it finally stopped. I could dive into this water.
The lake was beautiful but there was not a single living thing inside of it. It wasn't so big, but it was deep. As I was closer to bottom, the intense electricity started to attack me as if it had its own mind. Maybe it was my paranoia, but it was like something controlling those electric arcs.
It didn't take a long time for me to find the space where urn was hidden. It was beautiful urn with the lightning jumping around it. It was the source of the electricity inside the lake, and it was denser than the lake. Even with all my means, I could still feel tingling when I touch to the urn.
The Eight-Tailed beast was second strongest just after the Nine-Tailed Beast. Even though most of the Tailed Beasts didn't admit it but the more tail they have, the stronger they are. Also Eight-Tailed beast was smarter than the others. In the original series, it was able to create war tactics to lead its jinchuuriki in the battle.
