"What is this?" Echizen Kazuya, who was investigating the curse mark, soon found a very active substance in the spell mark left by Orochimaru, and thought in his heart.

After discovering the anomaly, Kazuya Echizen opened his eyes and took a closer look.

Because the heart eye can sense the distribution of energy, as soon as Echizen Kazuya opened the heart eye, he found that there was a lot of natural energy gathered near Sasuke's spell seal, and the density was much greater than that of ordinary space.

Echizen Kazuya was overjoyed to see this scene, and since the time when the eye of the heart was upgraded to the point where he could perceive energy, Echizen Kazuya has been trying to absorb the ubiquitous natural energy that is all over the space in order to solve the problem of lack of chakra.

So far, Echizen Kazuya has been able to absorb a small amount of natural energy around him for his own use, but the amount of that little natural energy around him is too small, and the effect is almost completely invisible after absorption, and Echizen Kazuya has not found a way to gather a large amount of natural energy.

Therefore, when he saw the large amount of natural energy gathered at the spell mark, Echizen Kazuya's joy in his heart could be imagined, and Orochimaru's spell mark was the method he had been looking for to gather a large amount of natural energy.

Suppressing the excitement in his heart, the expressionless Echizen Kazuya reached out and pressed it on Sasuke's spell mark, carefully sensing the active substance, and then using the pinnacle of the fine trouble extraction technique to carefully avoid the protection of Orochimaru's curse mark, and successfully extracted a few untraceable trace amounts of active matter from Sasuke's body.

But when Echizen Kazuya tried to extract more and wanted to help Sasuke solve the trouble of the spell mark once and for all, the spell mark seemed to be able to feel the decrease in active matter, and it activated without warning, and the spell mark pattern quickly spread to the rest of Sasuke's body, and in the blink of an eye, it was all over Sasuke's face.

"Ahh Sasuke, who was stimulated by the curse mark, suddenly woke up and screamed loudly.

Seeing this, Echizen Kazuya immediately stopped trying to continue to clear the active matter, and suppressed the spell mark that erupted with the help of Kakashi's evil sealing seal.

However, in the second inspection, Echizen Kazuya found that although Sasuke's curse mark was suppressed, the active substance under Sasuke's curse mark increased a little bit, and the active substance seemed to be the root cause of the erosion of Sasuke's body.

"Sasuke, are you alright?" Startled, Kakashi asked eagerly as he looked worriedly at Sasuke, who was gasping for air.

Sasuke, who had just woken up, looked at Echizen Kazuya and Kakashi beside him, clutching the curse mark that had just erupted, and said reluctantly, "I'm fine." ”

"Kakashi-senpai, this spell mark is very troublesome, its sensitivity is very high, I have found the cause of Sasuke's rampage, but I can't clear it for the time being, sorry." Echizen Kazuya also secretly put away the little bit of active matter that was so small that it was imperceptible to the naked eye that it was extracted, and said quietly.

"Really?" Hearing Echizen Kazuya's words, Kakashi, who had experienced many storms and rains, was as calm as ever and said softly.

"Well, there is a mysterious substance in the spell mark that attracts an energy in the space into Sasuke's body, Orochimaru's spell mark can make this energy and Sasuke's own chakra fuse, the reason why the chakra, speed, and strength will be doubled is because Sasuke's original chakra is integrated with that special energy!" Kazuya Echizen carefully explained that these were the things he had just observed when the spell mark exploded.

"Is that so? Is that spell destroying the body because of that energy? Kakashi asked.

"Not exactly, that energy itself should be harmless, but the amount absorbed is closely related to the amount of chakra itself, and excess will cause damage to the body."

"The main reason for the erosion of Sasuke's body is the curse mark itself and that mysterious substance, it may be the price paid to fuse the special energy with the chakra, or it may be that Orochimaru did it on purpose, and I haven't figured out the real reason!" Kazuya Echizen said calmly.

"Orochimaru that guy!" Kakashi sighed in a complicated tone.

"Kakashi-senpai, I'll go back and think about how to remove the hidden danger of the curse mark, and then treat Sasuke when I have a harvest, if you need anything, feel free to come to me." After Echizen Kazuya finished talking about his discovery, he immediately offered his farewell.

"Then please, Kazuya!" Kakashi thanked Kazuya Echizen for his call, and then sent Kazuya Echizen out of the ward.

Although the amount of active matter obtained by Echizen Kazuya was very small, after leaving Sasuke's body, the speed of gathering natural energy was significantly faster, and in order to avoid the abnormal movement of natural energy, Echizen Kazuya immediately found an opportunity to use the sealing technique to temporarily seal it after leaving the hospital.

Seeing Echizen Kazuya coming out of Sasuke's ward alone, Ino wisely didn't ask much about Echizen Kazuya's treatment of Sasuke, and said with a smile, "Brother, where are we going next?" ”

"Of course, it's for you people!" Echizen Kazuya replied with a pleasant face, "You also saw it just now, Naruto has already started special training, aren't you in a hurry?" ”

"Hee-hee, that's great, but dude, can you secretly tell me about the trick of the teeth?" Ino smiled slyly and said coquettishly.

"That's not good, and ninjas won't let anyone know their real hole cards, even with my understanding of Fang, it's impossible to know all of his tricks, you still rely on real strength to fight him, don't think about opportunism." Kazuya Echizen immediately refused.

"Hmph, really, I just want to have a little more advantage!" , Ino, who didn't achieve his goal, didn't mess around, but just pouted and said cutely.

"Then are you going to train with Asma or me?" Echizen Kazuya rubbed the little girl's head and asked with a smile.

"Of course it's with you, brother, and I've already told Teacher Asma!" Ino replied immediately.

Echizen Kazuya was not surprised by Ino's answer, and said with a pleasant face, "Really? Then you can fight against Ya and Hinata often, and as for how much information you can get about Ya and Hinata, it's up to you, and I'll treat them equally! ”

"Got it! I'm not going to lose to them! Ino said confidently.

After checking the injuries of Xiao Li and Sasuke, Echizen Kazuya took Ino, Inuzuka and Hinata to start special training, and also invited the oil girl Shino to come as a sparring partner, Shino readily agreed, because he did not enter the formal assessment, Shino, who was not willing to lag behind, is now very eager to become stronger, and of course will not miss the opportunity to receive guidance from Echizen Kazuya.

After a day of special training for a few people, in the dead of night, Echizen Kazuya calmed down to study the mysterious active substance obtained from Sasuke's spell seal.

Echizen Kazuya carefully used the chakra to control the small amount of something that was barely visible to the naked eye and suspended in his hand, and soon found that the natural energy around him seemed to be inexplicably attracted, quickly converging towards the substance in his hand.

Because of his experience in absorbing a small amount of natural energy around him, Echizen Kazuya skillfully introduced the converging natural energy into his body, and integrated it into his chakra according to the fusion ratio he had just sensed on Sasuke's body.
