More than a month later.

School is approaching.

Runzheng looked carefully at a structural drawing of the technique. From the scale bar in the lower right corner and the small-character markings everywhere, it is not difficult to see that it was written by Ding Ding.

Run handed the drawing to Nana who was beside him and said to Ding Ding: "No problem, at least I can't see the problem."

"You have surpassed me." Runyan looked at Ding Ding with a sigh. He didn't have much high-end sealing technique. His best attitude is to modify the shape of the basic technique and replace the materials to facilitate application in various fields.

But these techniques he was proud of seemed to be instinctive in Ding Ding's hands. The structure of the technique seemed to be changed as if it were plasticine, and he also wrote it on his own and wanted to draw it. Every time he changed the technique, he had to stay in seclusion and study it for a few days...

Genius...

Nana, who was standing by, looked around the drawings and looked around twice, and said, "I can do this thing, but are you sure you want me to do it? Let me tell you the truth, I haven't used traditional skills to create something in a long time."

"I don't want too many people to know about this weapon," Ding Ding shook her head, "Please trouble you."

"Okay!" Nana slapped the drawing on the table, "In the future, I can also say that I am a master who forged advanced ninja tools!"

I saw that the drawing was a deformed kunai, but the handle part was lengthened and thickened a lot, which was more suitable for people like Ding Ding to grasp it.

This is so integrated with the upper and lower parts, not like Kyushu, but like a thick nail.

There are countless carvings that look like decoration on the short thorns. According to the design, it is not a simple carving. Instead, it is carefully designed by Dingding. The grooves are first carved on the nails, then inlaid with metal wires, and finally fixed by high-temperature welding.

In other words, these total amounts may not be as big as Ding Ding's nails, but they offset the work results of Ding Ding's worth of nearly 10 million taels.

Chakra Metal. The most precious and valuable material in the ninja world, no doubt.

Chakra metal’s conduction efficiency and tolerance to chakra are even far beyond the meridians of ninjas. In other words, for ninjas, weapons made of chakra metal may be more useful than their own hands and feet.

Ding Ding also likes this feature.

But not as a weapon.

Theoretically, the essence of sealing and barrier techniques is that chakra operates on the fixed trajectory of the surgical styling, which is very close to the circuit situation. If there is a path that has a smaller "resistance" and a faster and faster circulation of chakra appears. The chakra that circulates in the surgical styling can be pulled away, which will lead to the failure of the entire surgical styling.

Yes, this is a universal method of cracking.

Of course, the principle is easy to understand, but it is not that simple when applied in actual application. There are corresponding countermeasures in a slightly more advanced form. For example, once most forms are run, they will deviate from the carrier of the form and use the chakra itself to build a relatively closed operation path - using the stroke to draw a stroke can break the barrier and seal, which is not that good thing.

That is, the chakra metal itself has a dimensionality reduction effect on chakra. Ding Ding also designed corresponding techniques to improve the effect of extracting chakra to ensure the general effect of its universal key.

Even so, many barriers and seals cannot be cracked, such as the Four Purple Flame Array that brings the caster into the interior, or the two Four Symbol Seals are coupled to each other, bringing each other's magic into the seal space, thus almost eliminating the possible Eight Trigrams Seals that can be used to resolve the external seal...

"Do you really want to use chakra metal in this kind of place?" Run hesitated for a moment, and persuaded, "There are not many ninjas in the ninja world who have established themselves through magic and sealing techniques, and they are usually not powerful.

Moreover, using chakra metal cracking techniques means that you cannot inject your chakra into your weapon. The moment the cracking technique is cracking techniques, the weapon will be filled with enemy chakra. It is easy to be taken advantage of by your opponent, and it will not be worth the loss."

"I understand." Ding Ding nodded, "but this is the only quick and universal way to crack the sealing technique I can think of."

Of course it is full of limitations. But if it is just to prevent exploration, stabilize chakra balance, and also a sealing technique designed to quickly unseal. This brute-force cracking method has a great possibility of success in one go!

"Ding Ding has his own ideas, so let's not worry about that much," Nana patted Run's shoulder, "Let's go, let's help me... Forget it, Ding Ding, it's better for me to help me. We have to fight the coal first and help me pull the bellows later."

Nana is not a simple blacksmith, but a ninja who forged it using chakra and techniques. The high temperature and pressure used for daily forging comes from techniques rather than furnaces.

However, chakra metal has extremely strong resistance to any chakra-filled flame and current. There is no way to use ninja methods and can only be shaped through traditional forging methods.

This is also why Nana asked Ding Ding instead of Run to help.

The ninja method requires debugging various techniques, and traditional blacksmiths are the most important.

After closing all the techniques in the forging room, Nana and Ding Ding were busy, pulling, annealing, pulling, and annealing...

Although Nana hasn't conducted traditional forging for a long time, after all, it all relies on the high temperature to process metal. The work of ninjas and blacksmiths is similar in many aspects. In addition, the chakra metal can accommodate chakra properties, so advanced ninjas can use chakra control skills to assist in shaping when processing it.

As for the final fitting welding work, Nana's specialty is even more.

In short, the finished product is almost exactly the same as Ding Ding’s idea.

Leap studio.

A detonation talisman is placed in the center.

Ding Ding held his nails aside.

After making a gesture to Rune not far away, he saw that the technique on the talisman paper began to glow, bringing up a trace of blue smoke and eventually turned into flames. When he was about to burn to the center of the talisman, he saw Ding Ding thorned up.

The flames on the detonation talisman immediately weakened, and at the same time, the chakra wire on the spike began to sway around the whirlwind light blue airflow.

"It's successful." Run on the side also breathed a sigh of relief and reached out to remove the barrier. "Congratulations, Ding Ding, I'm honored to be your teacher during this period."

"Thank you too, Mr. Run."

"Okay, don't completely lay down your skills after class in the future, and it just so happens that you can supply more to the store."

"Class?" Nana was stunned, "Ding Ding went to be a teacher? It's such a waste... No, I mean the teacher is good, it's stable, and there are still many holidays."
