"Well, I'll go back to my master first." Seeing that the affairs of the three of Kao seemed to be quite important and secretive, Zhixi suddenly said that he was leaving.

"It's not that important, and it's okay if it's Ji-hee, right, Killua." Kaora stops Ji-hee, who is about to leave, and asks Killua for his opinion.

"Of course." Killua turned to look at Jihee with a trusting smile.

Xiaojie looked at the three of them with a smile on their faces and opened the door: "Then let's go in." ”

When the four of them came to the room, Kao's eyes changed abruptly, turning into kaleidoscope writing wheels, and strong qi continued to circulate in Kao's body.

"It's stronger......" The moment the kaleidoscope was opened, Xiaojie and the three of them all had this feeling in their hearts.

"Kao, your eyes are very similar to Kurapika." Xiao Jie thought of the fiery red eyes that Kurapika also possessed.

Kao had explained to Xiao Jie and the others that he had the ability to illusion, but it was the first time he had opened his eyes to show it.

"Well, they're all fiery red, but Kao's eyes are slightly different, and Kurapika's eyes don't have those strange black patterns." Killua also remembers,

"That's because I belong to the same clan as Kurapika, and the change in this eye is caused by my trait telekinesis, and I believe that in the future, Kurapika will also open up his powerful ability through his eyes."

Kao had already decided to think of himself entirely as a member of the Guluta Clan.

"Trait Mindfulness Ability? What is that? Xiao Jie asked suspiciously, although he was puzzled, Xiao Jie could feel the power of this power.

"Uh...... It turns out that Yun Gu hasn't taught you yet? Kao was a little helpless to find out about this fact.

"No, can you tell us?" Xiaojie became more and more curious.

"Didn't you practice the Four Great Lines with Yun Gu here? You should know how to use wrapping, absolute, and practice, right? Kao was checking their progress.

"In other words, is the so-called trait ability the last part?" Killua was the first to react and understood what Kao was going to say.

"Killua is very smart. Yes, but not everyone falls into this category, such as Hisoka, who belongs to the change system, and is able to change his qi into a sticky and elastic state. Kao nodded.

"Hair is a technique for controlling qi at will, and it can also be said to be the culmination of the ability to gather thoughts, which can be divided into the release system, the enhancement system, the change system, the operation system, the embodiment system, and the trait system." I'm a trait, and you'll need to find the right type of ability for you.

"Is there any way to find out which system your qi belongs to?" Killua asked.

"Well...... I can't teach you this, and I ask your forgiveness. Because your teacher is Yungu, but it's not long since he told you about it. Kao rejected Killua's request, which was a sign of respect for Yun Gu and Xiao Jie and the others.

Kao remembers that when Jay and Oddya met Bisji, they refused Bisji's request to be their teacher on the grounds that their teacher was Yungu.

"It's okay Kao, it's our fault. Don't you have something important to say about Killua? Xiao Jie shook his head and said.

"yes...... I was accidentally led astray. Kao scratched his head and looked back at Killua again.

"Did something happen to me?" Killua was stared at by Kao, feeling a little uncomfortable.

"First of all, let me confirm that you know one of the abilities of my eyes." Kao picked up the pen and paper on the table next to him and handed them to Killuada.

"What is this?" Killua took it and looked at the pen and paper in his hand, not understanding what Kao was trying to do.

"You write whatever you want to write at random and hold it in your hand." Kao said, turning his back to Killua.

Killua didn't continue to ask, but nodded and wrote something on the white paper: "I'm done." ”

Kao turned around again, looked through the white paper hand that Killua was holding, and clearly saw the words on it: "Uh...... The word you wrote is - Xiaojie. ”

Killua let go of his hand, and on the white paper was the word 'Xiaojie': "Perspective? ”

"Yes, one of the features." Kao nodded.

"Now for what I'm going to say." Kao is close to Killua.

"When I first met you, I felt a subtle but unusual breath, and I searched carefully and found that it came from you." Kao placed his hand on Killua's forehead.

"That breath is coming from my head? Why can't I feel it at all? Killua was startled, and his pupils sharpened.

"Yes, when I opened these eyes, I clearly saw a tiny needle piercing your forehead." Kao nodded.

"How, isn't that bad?" Ji-hee became nervous when she learned about it.

"What should I do? Kao, can you take it out? Xiao Jie also looked at Kao with a worried expression.

"Yes, and Xiaojie, the person who put this needle is far from being an opponent, calm down first." Kao looked at Jay and could see the care and patience on his face.

"En......" Xiaojie lowered his head unwillingly.

Kao looked back at the gloomy Killua on his face, "Do you believe me?" Killua. ”

At this time, Killua looked up at Kao and nodded heavily, "Of course." ”

Kao smiled, then became serious again, "Well, don't resist. ”

As he spoke, Kao's hand stabbed directly into Killua's forehead, and blood flowed downward.

Kao's kaleidoscope chakra eyes stared at Killua's head, his gaze piercing through, clearly seeing the silver needle trapped in it.

"Ran into it." Kao pinched the silver needle.

"I'm going to start pulling out the needle, don't move." Kao instructed and began to confirm the position and force of the pull-out.

Taking a deep breath and pulling lightly, a subtle silvery-white light was pulled out of Killua's forehead.

"Okay, what do you think now? Killua. Kao asked as soon as he pulled it out.

"Whew-" Killua lowered his head and said nothing.

"How are you? Killua. Xiao Jie saw that Killua was in a strange state at this time, and couldn't help but worry.

"Suddenly I felt so comfortable, like I had fully woken up." As he spoke, Killua looked up at Jay and Kao, tears unconsciously flowing down his pure and clean eyes.

"It feels like you've been liberated, thank you, Kao."

"Great!" Xiao Jie happily hugged Killua and could feel the aura on Killua becoming calmer and purer.

"Alright, Xiaojie." Killua was hugged by Xiaojie, although he was also very happy, but he was a little embarrassed.

"In this way, the shackles on Killua's body will be untied first." Kao looked at the two of them and felt very warm in his heart.

After Killua let go of Killua, Killua walked towards Kao: "Can you show me the needle?" ”

Kao spread out his hand holding the long needle, and saw a purple-black aura flowing on the silver needle: "This is it." ”

Killua picked up the silver needle: "Hehe...... I didn't expect my brother to stab this thing in my brain. ”
