When Kei Ueno had finished dealing with the psychic scroll, he turned his attention to the knife.

It can be tied to the psychic scroll, it can be seen that this knife definitely belongs to the same owner as the psychic scroll, and the saber owned by the ninja who has the precious psychic scroll, Ueno Kei will never believe that it is a bargain.

And the blade is clear, there is not the slightest notch, and there is no rust or anything like that, only a lot of dust stains stained by the precipitation of time.

Looking at its style, it looks like a knife, and the blade has a slight curvature.

Kei Ueno put the whole knife horizontally in front of him, took a rag in his right hand, dipped it in some water, wiped off all the stains on the knife, and after a while, the whole knife became beautiful and clean.

To Ueno's surprise, Ueno thought that the stains would be difficult to clean up, as they looked like they had been buried under the river for a long time.

Kei Ueno gently held the handle of the knife and raised the entire knife slightly.

The blade was cold and seeping, and the sunlight through the window shone on the blade, reflecting into Ueno Kei's eyes, making him unconsciously squint.

"Hum" Suddenly, a soft moan sounded in Ueno's ears.

Ueno Kai's eyes froze slightly, and he looked at the knife in his hand with a slightly stunned expression, and at that moment, in Ueno Kei's opinion, it seemed that there was a feeling that this knife was alive.

And, it seems, as if the soft groan just now came from this knife, but when Kei Ueno listened carefully, there was no sound at all.

The knife is still the same as the original, it has not changed in the slightest, it is still a dead thing.

Ueno Kai's eyes flickered, he was a little unconvinced, after all, just now, he could be sure that he definitely heard a "buzzing" sound, it was definitely not an auditory hallucination.

And the most suspicious thing is the knife in front of me.

Kei Ueno looked at the knife countless times, as if he wanted to find a trace of suspicious points from it, but no matter how he checked it, Kai Ueno was deflated and found that there was no suspicious point at all, and the only thing that could be suspected was that when he injected chakra into the knife, there was no reaction at all.

Of course, there are also two possibilities, one is that this knife is just an ordinary knife, and it is not suitable for injecting chakra at all, but because the production material of this knife is relatively special, it is not easy to destroy, and then Ueno Kai's strength is too weak to destroy this knife. Another possibility is that the amount of chakra injected by Kei Ueno is too small to cause changes in this knife at all.

These two situations are not what Kei Ueno can be sure at the moment, after all, Kei Ueno even used the strength to eat milk, and he desperately injected chakra into it, but he was still sinking into the sea, and there was no reaction at all.

This made Ueno Kei very distressed, and he couldn't let Ueno Kai find a powerful ninja to try, Ueno Kai's brain didn't get into the water, which was the same as the psychic scroll.

All in all, after Ueno Kai looked at the Taidao in his hand for a long time, he shook his head helplessly, thinking that he was out of line, although today was a harvest day for Ueno Kai, but for now.

It's all things that can only be seen and can't be used, and it has no effect at all on increasing the strength of Ueno Kei at this time, "alas" Ueno Kai sighed.

He said to himself: "It's a good harvest after all, the psychic scroll is three or four years early, and six or seven years at the slowest, that knife is definitely a treasure, and then study it when it is strong in the future, or take it out later to exchange for other useful things." ”

Thinking of this, Kei Ueno planned to keep this knife as well and talk about it later.

"Hiss"

Kei Ueno's brows furrowed slightly, it turned out that when he turned to the blade of the knife, Kei Ueno was too obsessed with finding the suspicious points of the knife itself, and when he didn't pay attention, the blade cut through Kei Ueno's palm, cutting a scar, and the blood suddenly fell down the blade.

The stinging sensation made Kei Ueno gasp, not to mention how deep the wound was, which caused Kei Ueno to be unbearable to sting, on the contrary, the scar was very shallow.

It was just a little more blood, but at the moment when the palm of his hand was cut, Kei Ueno clearly felt a chill from the blade through the wound to Kei Ueno's body.

It made Kei Ueno shudder, as if it was frozen in an instant, and couldn't help but gasp. In order to soothe the cold in the body, it is slightly better.

Ueno Kai couldn't help but look at the unpretentious-looking knife in his hand in horror. Sharp, not to mention for the time being, Ueno Kai, for the sake of safety, first used chakra to attach to his hands before touching the whole knife, in order to prevent some possible accidents.

Even though Ueno Kai's strength is weak, but he is also a half-hung quasi-ninja, this knife can easily cut through his palm without the control of his master, if it is controlled by a powerful ninja, how lethal is it? If the knife can be infused with chakra, what will be the destructive power when the ninja infuses chakra into the knife?

Sharpen iron like clay! This thought suddenly came to Ueno Kei's mind, of course, this was reluctantly used when Ueno Kei couldn't find the rest of the adjectives, and Ueno Kei had every reason to believe that the hidden power of this knife was.

It's definitely going to be more than they think.

Moreover, that cold air, this time the feeling is no longer an illusion, and Ueno Kei can clearly perceive the shivering feeling brought by that cold air.

If you have to find a feeling to describe it, then the only conclusion that Kei Ueno can come up with is "murderous"

In this life, Ueno Kei did not feel the real murderous aura, but, in his previous life, when Ueno Kei was staring at him with indifferent eyes at the moment when his life was about to end.

Kei Ueno could clearly feel the cold, penetrating feeling emanating from that man.

At that moment, the only thing that Kei Ueno could be sure of was that feeling, it was definitely murderous, and what was conveyed in that cold look was naked killing intent!

It feels as if you can freeze time and space.

Therefore, when that cold breath invaded Kei Ueno's body, Kei Ueno could be sure almost without thinking about it, it was a feeling of murderous aura.

And it is quite possible that the previous owner of this knife remained in it.

After so many years, and there is such a clear and unambiguous feeling, that can definitely guarantee that the former master has killed countless living beings. to have such a feeling.

It's a psychic sword! Kei Ueno was sure at this moment, and just when Kei Ueno was looking at the knife again with great interest, what Kei Ueno didn't notice was.

The blood of Kei Ueno on the blade on the back of the knife seemed to be slowly absorbed by the knife unconsciously, and gradually merged into it.

Suddenly, the knife in Ueno Kai's hand shook violently, and a burst of light flashed away, and Ueno Kai subconsciously closed his eyes,

"Ahh

In an instant, Kei Ueno stopped screaming again, but at this time, Kei Ueno's eyes widened and he doubted his existence, because at this time, he was in an unknown space.

The four big characters of "Wind Wing Knife Technique" appeared out of thin air and appeared in front of his eyes.
