Everyone outside can't help but to jump to help but because of the barrier they can only watch from outside.
"Damn Hidden Cloud Ninja! So despicable!"
"You don't talk Martial Art!"
While everyone is shouting angry outside, the Shinobi of Hidden Cloud look confused, he sure that ita impossible for anyone to dodge such perfect sneak attack but for some reason he feel stabbing air and not solid.
"Ninja Art: Utsusemi ( Cast-off Cicada Shell )"
They then heard Lucci's voice awakening everyone in rage.
"Watch, and listen, don't be distracted it else I will throw you all to Hell Training Program later!"
Hearing Lucci's chilling voice, everyone finally snap out and start looking in front.
What they see is something that makes them feel they fall into Illusion Technique.
They can see Lucci standing while a sword stab behind and pierce in front of his chest, they can see that Lucci slowly become blur.
"Substitution Technique?"
All of them are confused again, how can a Substitution Technique don't leave a block of wood after getting hit?
"Substitution Technique? When?"
Kimo Shinobi was confused, how did he do that, how can a simple Substitution Technique show different than what they originally see it.
"Utsusemi moves at great speed to avoid attack, leaving an afterimage which can appear to have taken damage."
"In short, it's a Afterimage is left behind that Kumo Shinobi hit."
"And also, this is still Taijutsu Technique, I did not use Chakra when performing this techniquea, you can use it if you have enough strength and expertise."
Kumo Shinobi look at Lucci, he knows that this Uzumaki Shinobi is something that he need to akr seriously.
Using Ninjutsu is a must to win this, and from his observation, they can't absorb Chakra here but the Chakra inside of their body is useable.
"I'm going to get serious, Uzumaki Shinobi, be proud, I will use the Raikage's powerful Jutsu!"
"Lightning Release Chakra Mode!"
Lightning wraps around his body, this made Kumo Shinobi more powerful and making everyone feel danger coming from him.
"Oh? Chakra Mode? That's a good technique, I did not expect to see someone use it."
"I'm one of the Sandaime's Shadow Guard, I'm fortunate to learn this from Raikage in person."
"But, I can see you can only use it for five minutes base on the amount of Lightning around your body, and also, it's a incomplete technique."
"Do you know that you're killing your self if you continue using it?"
"So what! Kumo Shinobi is not afraid dying on a fight! Come Uzumaki Shinobi! Let's fight to death!"
Kumo Shinobi suddenly appear infornt of Lucci, with his fist larger than Lucci's head, he punch out.
