After they accepted Netero's invitation they followed him towards a special room.
Already inside the room, Leise looked at Netero, which was playing with a ball.
"So the rules are if you can take the ball before we reach our destination you become immediately hunters."
Leise, Killua, and Gon nodded.
Killua decided to go first and began to walk around Netero. Along the walk, Killua's body seemed to separate itself from each other forming countless doppelgangers of Killua.
This technique that Killua used was one of the most famous assassination techniques: Rhythm Echo. This technique along with a special breathing and pace would form the illusion that there were countless enemies instead of one.
Netero also was a little surprise seeing this famous technique here. He is so young but he can already employ this technique at this level, hmmm... That old fogey Zeno must be happy.
After a few minutes, Killua suddenly dashed after the ball but every time with no success. Netero always evaded without any trouble as if he was taking a stroll through the park.
After an unsuccessful attempt, Gon launched himself towards Netero. Hiya approach could be said to be the total opposite of the one that Killua used. He dashed straight using his abnormal strength and power output. But after some time, Gon also couldn't even touch the ball and so his attempt was also unsuccessful.
Netero looked at Leise at if saying, it's your turn. Leise faked a smile and said:
"Oh, no, no... If the two of them couldn't do it how the hell am I suppose to do it?!"
Netero's eyebrow twitched a little, so you are cocky enough to confront me in front of everyone else but you don't have the guts to try taking from me the ball.
"How about the three of you do it together?!"
Leise looked at Gon and Killua and nodded. Then suddenly the three of them dashed towards Netero.
Killua used his assassination techniques to disrupt Netero, Gon used his wits and strength to try and take the ball from him and Leise war only making small moves so that everyone moves could be linked and to flow smoothly.
In half an hour, Leise, Gon, and Killua were all sir on the ground with faces filled with exhaustion. Even after their hard work and their struggle they couldn't take the ball from Netero. Although a few times they were close, they were still outperformed by the President of the Hunter Association, Netero.
"Tch... I'm going. Come on Gon let's get out of here."
Killua began to walk towards the exit while exuding an aura filled with killing intent. It seemed like if Killua spent a bit of edges timbre with Netero it was possible that Killua would try to kill him.
"But..." Gon looked a bit reluctant while looking at Killua and Netero.
Leise on that moment intervened.
"Killua is right you should go with him. Even after all that this old man isn't even tired so it is to expect that we would never at least in this narrow schedule steal the ball from his hand. It bet if you go and rest."
"But what about you? Aren't you coming with us?!"
"I still have some things I have to talk with that old man about looking at my beloved." Leise feigned an angry look on his face while gazing at Netero.
"Oh. Ok after you finish talking with him you can go find us. After all, you are still a friend of mine." Gon talked with comprehension and his face filled with lovey-dovey feelings for friendship.
Then, Gon walked after Killua and son both of them exited the room.
After Gon and Killua excited the room, Leise shrugged his shoulders and looked at Netero with a serious face.
"Are you ready, old man? After I take the ball from you I expect that you comply with your bet!"
"Sure, young boy!Ahahahaa..."
Leise released a bit of his killing intent while am aura ox destruction began to radiate from him.
"Obliterate- Bringer of Doom (Massatsu sure- Unmei no tōshi)"
