In Gon's room.
Wing carefully examined the red thread around Gon's right hand.
It was completely intact.
There was no sign of a break.
For the past two months.
Gon hadn't used even the slightest bit of Nen.
Wing's tense expression finally relaxed.
He pushed up his slipping black-framed glasses.
"Very good."
Wing nodded.
"You kept your promise."
He reached out and untied the red thread.
Gon immediately sprang off the bed.
He moved his left arm around, then kicked his legs.
His bones had healed completely.
His remarkable ability to heal was astounding.
"Awesome!"
Gon's eyes shone.
"Mister, can I learn Nen now?"
Killua and Kurapika came in as well.
For the past two months.
They had practiced the basics of Ten every day.
The aura surrounding their bodies had become extremely stable and pure.
Wing looked at the three boys before him.
His eyes were filled with pride.
"Yes."
Wing's expression grew serious.
"Today, I'll teach you the advanced applications of Nen."
"Ren."
"And Hatsu."
He walked to the center of the room.
He had the three boys form a circle.
Luo Ye brought over a small stool and sat nearby as well.
He held a bag of potato chips.
He munched away with loud crunches.
"Guys, you know what I'm talking about?"
Luo Ye muttered as he chewed.
"This guy's about to start preaching again."
Wing shot Luo Ye a glare.
Then he ignored him.
"What we call 'Ren'..."
Wing began his explanation.
"Means releasing the aura produced within your body in a burst, at a faster rate than usual."
"This is a technique you must master for combat."
Wing closed his eyes.
His breathing grew slow and deep.
Suddenly.
Boom!
An immense, violent surge of aura erupted from Wing's body.
The furniture in the room shook.
