The strongest man in the ninja world

"Yes, let's try it first and then find something else if it doesn't work."

"...You go find Farr and let him deal with this tusker."

"You first cut the long tooth into the shape of a sword hilt, and then I will teach you the next step." The old ninjutsu master handed the long tooth the size of a wrist to Far.

Farr took a look and waved his hand without thinking, and the long tooth was broken into two pieces. Then he saw a burst of cyan light surrounding the root section, and the sound of cracking continued to come from it.

After a while, the aura disappeared, leaving behind powder on the ground and a sword hilt as white as jade. Judging from the size of the hilt, it is a one-handed sword, and it is very small. The sword head, sword handle and sword guard (hand guard) are very detailed, and there are several circles of anti-slip patterns on the sword handle.

"Okay, now you burn this sealing array in the middle of the sword grid." The old ninjutsu master handed a piece of sealing array design to Farr, "Make one on the front and back. The chakra guide line of this sealing array needs to be Aim in the direction of the sword body. Yes, you need to extend the chakra guide line. At the same time, pay attention to the uniformity when carving, so that the chakra gems can be evenly distributed and the sword body can be more stable." The old ninjutsu master instructed. Farr's movements, while explaining.

"Okay, now it's just a matter of the last few steps. Farr, grind this cryolite into powder." The old ninjutsu master handed the cryolite to Farr.

"No, use this one. It's useless if I keep it anyway." Village Chief Fal took out an ice chakra gem from his body.

"This is not good." Shuina said aloud. The color of this gem was much purer than that of Shuina.

"It's okay, he has become a sword master. There is no use keeping these foreign objects." The old ninjutsu master put away Shuina's ice crystal stone, then glanced at Farr and said, "Your chakra Don't be too overbearing, otherwise it will destroy the elemental power of the gem."

Farr crushed the gem with his hands and placed the powder in a small saucer.

"Oh, it's a pity. If it were all done by me, the effect of this gem could be 100% utilized. Now I'm afraid it's only less than 80% effective." The old mage saw that Farr had collected all the gem powder in a small box. It’s time to talk about the dish.

"Then..." Shuina was anxious. This old ninjutsu master would wait for the gem to turn into powder before telling him sooner or later.

"Look at you, although this gem is a little better than yours, it's just a little bit. It's just like a fart when it's gone. It's a big fuss." The old ninjutsu master evenly counted the numbers with a special pen. Apply little by little on the burned sealing array until one side of the sealing array is completely filled.

The sealing array completely filled with powder actually emitted blue fluorescence under the guidance of the old ninjutsu master's ice escape chakra, and slowly merged into one, just like the pattern growing on the hilt of the sword. After that, the old ninjutsu master did the same thing to the other side.

"Is this enough?" Shuina couldn't help but ask when she saw the old ninjutsu master looking at the sword hilt in his hand with admiration.

"No, there is one more step. I am checking to see if there is anything missing." The old ninjutsu master looked at it seriously, "Actually, it is very simple to carve the sealing array, as long as you make no mistakes. But when filling the gem powder It must be filled evenly, otherwise the chakra flow will be blocked, which will affect the stability of the sealing array. After filling, immediately use the sealing technique to re-form these gem powders into crystals, so that the ice can escape The chakra is sealed in it, and finally a crystal core with corresponding attributes is added as the ice escape chakra supplier." The old ninjutsu master said as he took out a gemstone about the size of a gem, with edges and corners. The blue crystal core comes out.

"This is..." Shuinai has never heard of the term "crystalline core".

"What is taken out from the body of the monster is the source of the chakra ability of the monster. However, only a few of the crystal cores of the monsters will remain in their original shape after death." The old ninjutsu master asked Farr to cut off the two corners of the crystal core. Then the crystal nuclei were melted into the centers of the two sealing arrays, and each of the two blue crystal-like sealing arrays had a slightly bluer "eye" in the center.

Finally, the old ninjutsu master let Farr drive the remaining crystal core body into the sword grid between the two sealing arrays. This position happened to be the end of the sealing array's chakra guide line.

"Well, not bad, better than expected
