The whole person seemed to be transformed, only to see that Killua's fiery red short hair began to grow at a speed that was visible to the naked eye, and after a while, he had already reached the position of the waist, and his body and appearance, which originally looked like twelve or thirteen years old, had completely changed into a handsome young man of twenty-four or five years old at this moment.

At this moment, Killua's whole person was like a burning flame, wrapped in fiery red martial breath, and on the spiritual weapon 'Butterfly Slash' in his hand, the terrifying and smack-smacking heat energy was constantly devouring everything within a few feet of the surroundings.

"The Seal of the Curse - Open!"

As Killua shouted, finally, the secret 'Curse Seal' used in the assassination family's cultivation was completely unraveled by Killua .

A handsome but cold face, full of fierceness and confidence, Killua slowly raised the 'butterfly slash' in his hand, and with a clever flip, as soon as he made a move, it was a shocking assassination.

"Red Butterfly - Drama Flame!"

Eighteen flame butterflies coiled around the giant crab-shaped phantom beast, under the attraction of the 'butterfly slash' in Killua's hand, flew towards the phantom beast at the same time in an instant.

Sneer......

The sound of the collision of fire and water continued to reach the ears of Youkuang and Liu Yan, and there were eighteen before and after!

"Ignoring the factor of the five elements, and using the flame move to fight against the water-attribute phantom beast, this!"

His eyes widened, and Liu Yan's face was full of disbelief. Killua's approach is simply out of line with common sense, and it doesn't look like what he, who is known for his calmness, would do.

I have to say that today she was really shocked by the two boys Yu Kuang and Killua .

However, the shock given by Killua seemed to be just the beginning, at the moment when the eighteen flame butterflies rushed into the body of the huge crab-shaped phantom beast, the original imposing and ferocious phantom beast was rapidly wilting at this moment.

"Is water overcoming fire? Hehe, what if it's a flame that can't even be extinguished by water? The principle of mutual growth and mutual restraint only exists in common sense, how can different levels of fire and water be judged by common sense, between this heaven and earth, there are many things that are not in line with common sense......

The corners of Killua's mouth set off a slightly weird arc.

That's a grim smile that only top killers have, which makes people fearful, makes people shudder, and makes people desperate!

In just a few respites, the crab-shaped phantom beast, which was as huge as a small boat, had already been evaporated by the eighteen flame butterflies and directly turned into nothingness.

It didn't even send out a decent attack, and it was completely scattered between the world by Killua's blow.

"Hmph, it's a busy day, and it's just an empty shell. ”

With a light snort, I saw Killua flip with one hand, and the spiritual weapon 'Butterfly Slash' in his hand had disappeared in just the blink of an eye, and his body was also rapidly shrinking, and after a while, he returned to the appearance of a twelve- or thirteen-year-old boy before.

"Gone. ”

After beckoning to Yu Kuang and Liu Yan casually, Killua continued to walk in the direction of the depths of the ancient forest.

The genius of the killer family really lives up to its reputation!

This thought was rising in the hearts of both Yu Kuang and Liu Yan at the same time.

If this person is on the opposing side, then it will be a very troublesome opponent.

"Is this a spiritual artifact...... , It's really tough, it's really attractive enough, no wonder Killua always looks fearless, I didn't expect to have this kind of magic weapon on his body, and besides, this guy also has the art of spell seals, Wu Kui Seven Stars, right...... , I don't know where this guy's real strength has gone, Killua this, this shouldn't be the bottom limit of your real strength!"

Witnessing the power of the spirit weapon with his own eyes, at this moment, his mind was still stuck in the picture of the 'butterfly chopping' in Killua just now, and his heart was constantly surging.

Because he knew that his 'Xiao' was also transforming towards the level of a spiritual weapon in the storage necklace on his chest at this moment.

It's just that I don't know what the difference will be between my 'Xiao' after the transformation and the spirit weapon-level divine weapon in Killua's hand that has not undergone transformation and is finished at the time of the finished product.

It's really a lot of anticipation.

got up and patted the dust stuck to his body, nodded to Liu Yan beside him, and both walked towards the depths of the ancient forest.

Along the way, a secluded heart can never calm down.

"The two of you, before you reach the desert area, can you let me complete the next battle alone? Of course, if there is any treasure I get, I won't swallow it alone, or the three of us will share it. ”

The two of them, Qilu and Liu Yan, made this request.

After seeing Killua's battle, Yu Kuang deeply realized that the strength he currently possessed was really nothing if he was placed before a super strong person like Killua in terms of strength.

You Kuang is a person who observes very subtlely, the battle just now of Killua, from beginning to end, there is only a short time of ten breaths, and every action of Killua, every martial breath, is used just right, there is no procrastination and waste, not to mention anything else, this kind of actual combat experience alone, is far beyond Youkuang.

Therefore, Yu Kuang felt that he had to increase his combat experience in the next period of time, whether it was against phantom beasts or competitors.

"Oh, yes. Feeling that Youkuang seemed to be preoccupied all the way, Liu Yan seemed to see through Youkuang's mind and agreed very happily.

"Whatever you want. His hands were still lazily holding the back of his head, and Killua was also full of care.

If only this was the best, it would save you the trouble of always having to break the curse seal.

"Well, thank you in advance. Yu Kuang nodded and thanked him.

A few hours later.

"Whew, finally killed ......"

He exhaled a long breath, and after dealing with the three six-star martial artists of the Rainbow Abyss, Yu Kuang wiped the sweat from his forehead, and let the silver spear 'Xiao' lock the flowing essence * blood of the three martial artists again, and finally he was so tired that he 'pounced' and sat on the ground.

Took out an elixir from the storage necklace and swallowed it in his abdomen, as in the previous few times, after the fierce battle, he chose the practice of immediate pranayama, and stabilized the turmoil caused by the galloping martial breath in his body as soon as possible after breaking through the six-star martial arts.

After all, the speed of advancing to one star in one night is too fast, and if the follow-up is not so stable, then I am afraid that it will be difficult to improve in the future.

On the side, the silver spear 'Xiao', which is about to step into the ranks of spiritual weapons, has no previous colorful colors on the body of the spear, and instead of it, there is a little bit of silver and white starlight lingering, symbolizing the awakening of spirituality, and it has entered the final stage.

One person, one gun, relatively silent, while Liu Yan Qilu and the two people on the side were silently guarding.

"This kid seems to have changed a little since the battle I unsealed the spell. Killua rarely took the initiative to say to Liu Yan.

There have been ten battles of all sizes along the way, and this kid didn't even use his 'Fire Eye Demon Pupil' and that silver spear again, no matter how difficult the opponent was, he always used his martial strength of the six stars of his martial arts, and some low-level martial arts such as the 'Storm Palm Technique' and 'Burial Mountain Technique' to face the enemy, as if he was deliberately exercising something about himself.

And these things, Killua naturally saw them in his eyes, and his interest in the seclusion became more and more intense.

"yes, he probably thinks you're a goal to work towards. ”

Liu Yan looked at the secluded young man who was sitting down, and a rare smile of relief appeared on his face, "Maybe you don't know about the secluded young master, but I heard something from Miss Youlan, the secluded young master, he ...... , is a person who never wants to be protected, but always wants to protect others, and the strength you show may make him realize that he still has a big shortcoming. ”

"Oh?"

Liu Yan's words immediately aroused Killua's curiosity, "This kid ...... Have you been through anything before?"

"Hmm. Liu Yan nodded and continued: "The young master has been abandoned by the whole family since he was very young, and even all the people of the demon race, there are very few people who grew up with him, he has been surrounded by loneliness since he was a child, and he has grown up slowly, the reason why he has been working hard until now is to make himself and the people he values no longer be bullied and looked down upon by others as he was when he was a child, so now as long as it is the person he identifies, he will definitely do his best to protect it."

So he was very disgusted that he was weak, and there was no one who could desire more strength than him, because he wanted to protect the people he cared about the most, the people he valued the most, and he had lost too much, too much......"

"Abandoned by All......"

Killua muttered, "No wonder I feel the same taste as me from this kid." ”

He couldn't understand the pain, but he knew deeply how torturous it was to feel the hesitation and deep fear when he was alone and helpless.

Because since he was a child, he was trained in such an environment to become the cold-blooded and cruel character he is now, and he has no superfluous emotions like ordinary people at all.

All he was taught from childhood to adulthood was how to kill, and there was always a fear of the shadow of death, and he was trained in bloody killing. How to perfectly kill a person, or even a group of people, is the most trained Killua has received since he was a child.

So, he knows exactly what it's like to be alone.

Although now, he is very numb to the feeling of loneliness.

"You and I can have today's cultivation because we have a huge family behind us, and we didn't even encounter any decent difficulties, so we easily reached today's level of cultivation, but the young master is different, he relied on himself step by step, and it was difficult to get to today. ”

Speaking of this, Liu Yan couldn't help but feel a little emotional in his heart.

It's really unfair for God to treat everyone.

Through the light from the depths of the ancient forest, you can already see the looming desert area in the distance, and for some reason, after this brief conversation, Killua and Liu Yan have a strange emotion in their hearts for the seclusion at the same time.

Is it sympathy, or admiration?

The answer is unknown, but the two of them secretly decided one thing in their hearts, that is, they made up their minds about this friend!
