What Yamanaka Yuan wants to develop is a medical charm like a detonation charm.

Yamanaka Yuan accidentally saw Tsunade's exclamation when he was flipping through Tsunade's notes before, if there was a medical ninjutsu that was easy to carry like the detonation charm, the survival rate of ninjas would be much higher.

If it weren't for the death of Rope Tree and Broken Succession, which hit Tsunade deeply, the idea of the medical talisman might have been realized by Tsunade.

In his previous life, Yamanaka had seen all kinds of talismans in fantasy novels, and there were ready-made detonation talismans in the Hokage world for him to study.

The detonation charm is a high-level fire escape ninjutsu sealed in the form of runes in the paper of the trait, and when used, it is no less powerful than the fire escape of the upper ninja.

Yamanaka Yuan planned to draw a gourd in the same way, trying to seal the [Healing Technique] in the form of runes.

Most of the seals of the detonation charms are [Fire Sealing Law Seal], and the sealing [Healing Technique] Yamanaka Yuan intends to use the [Evil Sealing Law Seal].

Yamanaka Yuan remembered that the [Sealing Evil Law Seal] in the original book could even seal the spell seal with natural energy, and sealing the [Healing Technique] should not be a problem.

However, Yamanaka Yuan failed, and the [Sealing Evil Law Seal] could indeed seal the chakra containing the [Healing Technique], but Yamanaka Yuan ignored one point, the [Sealing Evil Law Seal] was originally a technique that acted on the human body. The paper simply can't hold the runes of the [Seal of the Evil Seal].

After the failure of the [Sealing Evil Law Seal], Yamanaka Yuan could only find another way, during the period [Five Elements Seal], [Fire Sealing Law Seal], and even the [Four Elephant Seal] that he couldn't use proficiently had tried, but none of them succeeded.

The [Five Elements Seal] and the [Fire Sealing Law Seal] can't seal the [Healing Technique] at all, and the [Four Elephant Seal] and the [Evil Sealing Law Seal] can't be carried by paper.

The successive failures made Yamanaka Yuan very helpless, but he didn't want to give up, if the healing charm could be successfully studied, first of all, the lives of Yamanaka's relatives and friends would be guaranteed, and secondly, the property income of the Yamanaka clan would be more, and finally there would be three generations of Hokage who would also owe him a great favor.

"Little ghost, are you practicing sealing?" Just when Yamanaka was at a loss, Zilai also appeared.

Jiraiya has just come out of the office of the three generations of Hokage, and the frequent actions of the sand shinobi have made the three generations of Hokage very annoyed recently, and he plans to send someone to investigate.

Speaking of inquiring about intelligence, the most trusted of the three generations of Hokage in Konoha is Jiraiya, and this errand naturally falls on Jiraiya's head.

Jiraiya originally planned to leave the village immediately, but when he passed by the third training ground and saw Yamanaka Yuan scratching his ears and cheeks, Jiraiya still walked in.

"It's Uncle Jiraiya! It's not about practicing sealing, it's about developing one. Yamanaka replied.

"Look at the way you look, are you researching medical charms?"

"Uncle Jiraiya, how do you know?"

"If you use this technique, you might as well give up, little ghost. The predecessors have been developing for so long and have not succeeded, how can you easily get it? Jiraiya patted Yamanaka Yuan's shoulder and said.

Hearing Jiraiya's words, Yamanaka was taken aback, it turned out that someone in the Hokage world had already studied the healing charm, but it didn't succeed.

"Uncle Jiraiya, why did the seniors fail?" Knowing that someone had done similar research, Yamanaka wanted to know why his predecessors had failed, and maybe it would be enlightening.

"Well! I remember Tsunade saying that it was the reason why medical ninjutsu could not be stored for a long time. Jiraiya replied after thinking about it.

"Uncle Jiraiya, what technique did the seniors use to seal the medical ninjutsu?"

"It's not clear, you should ask Tsunade or Orochimaru. I'm not interested in that kind of thing. Little ghost, don't waste time on this kind of thing, the war is coming again, improve your strength more. After saying that, he left without looking back.

Yamanaka Yuan has never been a person who easily admits defeat, and the failure of his predecessors does not mean that he will also fail. Edison failed to invent the light bulb more than 8,000 times and experimented with more than 7,600 materials.

In the following month, Yamanaka Cosco experimented with various materials that could conduct chakra, but did not find any materials suitable for sealing medical ninjutsu.

"You haven't given up yet, little ghost!" Jiraiya, who returned from the investigation of information in Sand Ninja Village, found that Yamanaka Yuan was still researching.

"Uncle Jiraiya, you're back." In the mountains, there was a weak person who said hello to Jiraiya.

"Ahem, little ghost, I asked Orochimaru by the way before, and he said that the material for sealing the medical ninjutsu was jade." As he spoke, he threw a piece of jade to Yamanaka.

"Jade?" Yamanaka Yuan slapped his thigh, how could he not have thought of it. In his previous life, how many years of bookworm career, all the novels of cultivating immortals were read in vain.

Yamanaka Yuan took the jade that he had thrown from Jiraiya, and this time the runes of the [Sealing Evil Law Seal] were successfully engraved on the jade, and the [Healing Technique] was also sealed in the jade.

Yamanaka felt the [healing technique] in the jade. Sure enough, as Jiraiya said, the medical chakra contained in the [Healing Technique] is really slowly draining.

Strictly speaking, medical ninjutsu is also a type of Yang Dun, but it does not have the effect of miraculous healing like Yang Dun.

"Uncle Jiraiya, do you think natural energy can stop the loss of medical chakra?"

Yamanaka Yuan remembered that after the original Hokage Thousand Hands Pillar used the immortal arts, Mu Dun's power increased greatly, and his recovery became faster. Medical ninjutsu was originally developed based on the rapid healing of the Thousand Hand Pillars, and if natural energy was added to it, would it be more stable?

"Well! I'm not sure either, little ghost you can try. ”

Yamanaka Yuan entered the Immortal Mode, used the [Healing Technique] and then used the [Sealing Evil Seal] to seal the [Healing Technique] in the jade.

Yamanaka Yuan once again felt the medical chakra in the jade, and the [healing] medical chakra with natural energy did not lose the slightest thing.

"Uncle Jiraiya, look." Yamanaka Yuan handed the jade to Jiraiya, and after a period of inspection, the medical chakra in the jade still maintained the same appearance at the beginning.

"Little ghost, you seem to have succeeded!" Jiraiya looked at Yamanaka Yuan with some disbelief, if Yamanaka Yuan's experiment was really successful, it would mean too much to Konoha .

"Uncle Jiraiya, is the jade of Konoha expensive?"

"The gratuity for a C-class mission can be bought for three or four dollars."

The price of jade is not cheap, and it is generally always on women's decorations, and Konoha ninjas basically do not buy it.

"Uncle Jiraiya, we still need to observe whether this technique is successful or not, if it succeeds, uncle, you can go and talk to Hokage-sama."

Jiraiya nodded, this technique is of great significance to Konoha and must be told to the three generations of Hokage.

If the research on the healing talisman is really successful, Yamanaka Yuan is not worried that Konoha will swallow it alone, and if he wants to maintain the medical chakra of the [healing technique] in the jade, he must use natural energy. And the only ones in Konoha will be in the immortal mode are Yamanaka Yuan and Jiraiya.

Now Yamanaka Yuan plans to return to the Yamanaka clan and explain the situation of the healing charm to Yamanaka Haiichi.
