Unless it is an extraordinary material, ordinary metals follow such a law.

The harder, more wear-resistant material is, the more fragile it is, the less likely it is to bend, and the less able it is to withstand the stress of a sword collision.

Although chakra metal can conduct chakra, it still has the characteristics of ordinary metal.

Therefore, the Pingya people first purified the chakra metal, trying to make these metal ingots have the basic properties of transcendent materials and absorb the aura by themselves.

But failed.

Even if the metal ingots were purified to the limit, there was still no self-absorption of chakra, but as soon as they left the Pure Spirit Fire, the rate of oxidation became very fast.

But unfortunately, when he forged the instantaneous bracelet, he discovered that the impurities of the chakra metal would affect the structure and stability of the spell.

So purification is needed.

The chakra ingot, which has been purified to the limit, is smelted with high-carbon steel and nickel-chromium alloy.

Calcining, thrashing, quenching, and sealing the runes into the blade after the last time the blade is hot.

He took a deep breath and slowly lowered the knife into the water.

Zila!

The pitch-black blade emerged from the water, and Ping Yaren sighed and failed.

As soon as he threw it, the blade of the knife smashed to the ground and shattered into several pieces.

It seems that the main factor in maintaining the stability of chakra metal is those impurities.

Tsk, I really want a few hundred kilograms of Xuanyu steel to cause trouble, but unfortunately there is no special jade in this world, and I can't make it with a formula.

A little bit of groping, constantly returning to the furnace to rebuild, Ping Yaren forged eleven ninja swords the day before the middle ninja exam, seven of which were short daggers.

These seven short daggers are engraved with the spell of the Poison Mushroom Explosion Technique, which is too complicated, so it can only be activated when all seven short daggers land to form a formation.

However, the power has increased a lot, not only the toxins that paralyze the nerves have become stronger, but the parasitic ability of the green mushroom has also increased a lot.

When he returns to the Overworld, he intends to use it to attract the attention of the serpents in the Great Mountain Valley.

Two are Tai knives, one is what he left for himself, and the spell that sealed it in was the seal of steaming from Tang Ninja Village, which was very lethal.

But if the other party reacts quickly and uses chakra to block the wound, it will greatly weaken its power.

The other handed the Pingya man to the Moonlight Blaster behind him.

At first, he didn't want to save this insignificant person, even if he had a reluctance, his body temperature and breath would reveal his existence, and his girlfriend would naturally solve him in the future, which was not worth mentioning.

But the system gave him a side quest after the qualifiers, asking him to save this current charge, and the rating was still so much three points.

Ask the system, and the explanation given is that this person is the only descendant of Thoroughfare, so he has a certain amount of luck.

Tsk, this is now charged, and he is cheaper.

So on the second day of the furnace, he asked for the help of the third generation, and found a person with a blood inheritance limit to study the casting of the ninja knife, and the reward was the knife, and he deliberately delayed it until today to successfully cast the knife.

The knife is incantated by the blood of the Moonlight Blast, and when it is made, it makes the wielder transparent, absorbs the chakra of his lungs, and alleviates his cough.

This made him very happy, and he directly named the Tao "Xi".

The newly obtained ninja knife must be familiar, and tomorrow is the middle ninja exam, and as the chief examiner, he can't be on duty tonight.

If he is killed tonight, it can only be said that he has done his best, and you can't be saved.

A rib cha, sealed with a water escape rune, this is for Xiang Li, she can use this knife to perform ninjutsu like water breaking waves.

As for the last small knife, Pingyaren knocked on the door of the cubicle.

"The adults inside the labor, please take care of the three generations of old men."

“……”

After a while, the three generations arrived at the hotel where the Pingya people settled.

And he had already come back to take a shower and wait.

"Well, for you, old man, this is a thank you for borrowing my place.

Although you and Uncle Jiraiya teamed up to trick me once, I also understand what you did, so forget it.

Take this knife, and we'll clear it up. ”

The three generations smiled and were noncommittal.

"What is this knife capable of?"

"The moment the knife is drawn, a Vajra barrier will be propped up, pushing all the people around it away, this is a guardian blade."

The three generations of eyes lit up, pulled it out on the spot and tried it, and his room was in a mess in an instant.

Fortunately, Pingya people hid far away......

"Old man......"

"The compensation is mine, not bad, I didn't expect you to be so young that you can actually make a real ninja knife, amazing."

"This is a real ninja knife, don't talk nonsense."

"Huh? Isn't such a ninja knife yet? ”

He tried it, and he could continue to use it in about seven or eight seconds, and he could use it as the core to create a new school of swordsmanship.

"It's really not, this knife will lose its power after it is broken, and it will be useless after repair, and it is far from the real ninja knife."

The three generations were stunned, and the little guy's requirements were quite high.

However, it is true that there is a record of the repair of the ninja sword by the fog ninja, and if it is really calculated, then this guardian blade is indeed not as good as the seven.

"Why don't you fix it?"

"No, the internal spell was forcibly pressed into it with a sealing technique, and it was messed up as soon as it was broken."

Unless it falls into his hands, he will bring it back and strengthen it with other transcendent metals.

"That's a good ninja knife."

"That's, it's not easy to break this knife, old man, have you been smoking again these days? As soon as you enter the door, there is a smell of smoke. ”

"Ahem......"

"Old man, let me tell you, when people are old, they have to take good care of them, you ...... Eh, don't go. ”

"I still have a job, I'll talk about it next time, I'll talk about it next time."

Pingyaren looked at the departed figures of the three generations and thought about the next action.

Aunt Snake, who has mastered the core technology, will definitely not let it go and hinder his Konoha collapse plan, but I don't know what hole card it is in the end.

He had now shown his worth, the technique of forging ninja blades, the means of removing dark wounds and healing, the sealing technique that was stronger than that of ordinary Uzumaki clans, and the plausible wooden escape.

Next, as long as the plan is successful, he and Xianglin will be treasures in the eyes of the villagers of Konoha.

Regardless of whether the three generations can survive or not, he estimates that the old man will not continue to be the Hokage, and he is used to being wild, and Tsunade will definitely take the position.

As long as Tsunade knew about his existence, he might be able to blend in and settle in Konoha.

After another year or two, he would use the excuse of cultivation to go out.

Well? If three generations don't die, Orochimaru won't go to unlock the ghoul seal?

So what? It's a big deal to dig up a Blood Wheel Eye from the group and solve it with Izanagi.

He even had the idea of taking advantage of the chaos to attack the group and gouge out his eyes for treasure.

The intercolumnar cells and the blood wheel eye are all in him, and once he succeeds, it will be blood earning.

Take your time, take your time, and when he recovers to the strength of the upper ninja, he will make this old pot a fool completely.

Pale Flame Shadow is on standby.

Early the next morning, the official competition of the Zhongnin exam opened.
