Ning Ci picked up the knife box and suddenly felt cold and piercing. But he didn't think much about it, gritted his teeth and picked up the iron box engraved in the shape of a knife, and handed it to the pharmacist. The medicine man pushed the iron box out with a single palm and landed under the star. Miraculously, the tin box wasn't burned! The melted star water dripped into the original carved knife mold little by little.

"Young Master, what is that box?" Ning Ci asked.

"Cold Iron." Yakushi Li said lightly, "Naruto, sword spirit!" ”

“OK！” Naruto threw a blue bottle to Yakushi.

"The Qiangua opens the gate of heaven, the Kun hexagram closes the underworld, the Xunmu towers to the heavens and the earth, the Gen hexagram is the Great Wall, the Kan hexagram swells the waves, the palace is burned, the thunder is slashed, the hexagram is unified with the male soldiers, the left step on the three elements of the Taiji, the right step on the three elements of heaven and earth and the people of the Beidou, the heavenly sword is inserted into the ground, the gods retreat, and they are as anxious as the law! Bagua Secret Mantra: The Soldier and the Spirit are One, and the Soul is Together! The pharmacist opened the cap of the bottle, cut his finger, and dripped a drop of blood in the bottle. The blue gas in the bottle suddenly boiled, and under the guidance of the Medicine Master Li Fa Seal, it entered the knife that was taking shape.

The knife tire suddenly trembled violently, emitting a dazzling white light, as if it was about to explode again. Yao Shi Li hurriedly formed a magic seal to control the fire of the Bagua Furnace.

"It's not going to explode again, is it?" Naruto swallowed.

"Uh...... Let's stand back a little bit......" Ning Ci said.

Naruto was stunned for a moment, then laughed, "You kid finally said something like that......"

"No way...... It's been a day......"

"That'...... Let's take a step back......"

"It's good ......"

So the two of them took three steps back in unison.

For some reason, as if sensing the excitement of the knife, it suddenly lost control and rushed towards the knife tire like crazy. And the light on the knife tire is getting better and better, and the person who stabs directly can't open his eyes. A drop of sweat also flowed from Yao Shili's forehead......

"Oh no! The gossip furnace reacted too violently and was about to explode! Run! ”

"Damn! I knew it! Naruto screamed, and the first one rushed out.

"Boom!"

There was a loud bang. I don't know if it's because the energy of the star is too strong, anyway, Yao Shi Li didn't be able to block the power of the explosion this time even if he got the golden wall and the earth wall with the vajra magic circle outside the wall. Yakushi Rena's floor that had been ravaged for a day was finally reimbursed, and the Bo Feng family's house was missing, not to mention, the explosion also caused a three-level earthquake to Konoha, of course, this is a story for later...... In short, Yao Shili has to go bankrupt again...... Of course, it refers to the month......

When the smoke cleared, the surrounding scene finally became a little clearer. The house that Yakushi Li used to refine weapons and develop ninjutsu was completely in ruins, and there was a big pit.

"Brother, this time it's a big loss! Not only is the star gone, but there is also a house outside! Naruto said with a sad face, "I'll just say that there's nothing good about your character......"

"No!" Suddenly, Ning Ci's voice came, and he was looking at the big hole over there with his eyes open, "I feel that there is an extremely powerful chakra fluctuation over there!" ”

"Perhaps...... This time it's the explosion of character again......" Yao Shi Li smiled, he opened the kaleidoscope early in the morning, and he could naturally see it.

The smoke cleared, and in the crater, a knife was pressed against the rocks...... A strange knife......

The smoke cleared, and in the crater, a knife was pressed against the rocks...... A strange knife......

The dark blue blade exudes a bewitching light that devours people's hearts. The crystal box and the star fused together, turning into a purple-black crystal hilt, crystal clear. The pattern that fits the pattern of the palm is streamlined and gorgeous, and the edge goes straight through the blade. It was as if for a moment, everyone felt like they were about to be cut open by that sword!

But in the blink of an eye, the knife seemed to have turned into an ordinary and simple knife again, with a dull luster and inconspicuous appearance. It's the kind of stuff that you can find on a stall and you'll find a whole bunch of stuff. The sharp edge of Fang Cai seems to be the illusion of everyone.

Naruto rubbed his eyes in disbelief, and rubbed them again, but he never saw the knife that seemed to be able to easily chop people into pieces, and couldn't help but look at Yakushi Li suspiciously: "Brother, is this a waste product?" ”

Ning Ci also looked at the knife carefully with his white eyes, but he couldn't see the slightest chakra fluctuation! Even if the refining fails, there will be at least a slight chakra fluctuation! But this knife didn't have a trace of chakra fluctuations! Is it really as Naruto said, this knife, really- scrap?

There was still no expression on Yao Shi Li's face. It's calm, and it doesn't make it clear whether it's joy or sorrow. Naruto couldn't help but take a step back, this expression of Yakushi Li made him feel a little scary, usually Yakushi Li is the most dangerous in this poker face state. Because once he transforms into an angry expression, then they will also suffer...... The green silk whip that was finally refined was exchanged for such a waste product, which would make everyone depressed and angry.

However, Yao Shi Li only opened his palm slightly, and the knife flew into Yao Shi Li's hand. Yao Shi Li gently stroked the dark blue knife surface with his fingers, as gentle as his lover. The moment Yao Shi Li gently grasped the hilt of the knife, suddenly it seemed to change suddenly, and the sharp knife appeared again, and an extremely sharp chakra fluctuation poured out from the knife. Naruto noticed that even Yakushi's eyes had become sharper than he had ever been.

Yao Shi Li held the knife and gently waved it to the side, and an extremely small crack appeared on the tree on Yao Shi Li's right. After one another, it was as if it had become another knife, that quaint knife. It was very strange, as if a sharp soul was attached to the knife after Yakushi Li held the hilt of the knife, and left after Yakushi Li swung the knife.

Medicine Master's sharp eyes slowly eased, he looked at the fine marks on the tree, smiled with satisfaction, and then brushed the knife.

"It's not good!" Naruto walked over to look at the thin mark on the tree and said, "Even if it's not a failed work, it's far less powerful than the Blue Silk Whip!" ”

Yao Shi Li glanced up at him and smiled. didn't speak, but turned his head to look at Ning Ci. "Ning Ci, you should be able to see it with your white eyes."

Ning Ci didn't hesitate at the moment, and immediately opened his eyes and looked at the tree.

"This ...... This is? Ning Ci was stunned.

"What? Is there anything strange about it, I see it too...... Kindness? Naruto touched the crack slightly, and suddenly, the whole tree broke in two from the crack and fell straight down.

"This is ......" Naruto swallowed and gestured at the distance between Yakushi Li and here, "Isn't it, 5 meters away, you can cut off a tree with a knife without chakra?" ”

"No, it's not just that!" Ning Ci pointed to the top half of the tree and said, "Look at the center of the tree for yourself!" ”

"The center of the tree?" Naruto walked curiously over to the broken top half of the tree and touched it lightly with his hand, "Huh? This...... What's going on? ”
