Seeing Megumi successfully use a complete Domain Expansion, Eichi showed a satisfied expression.
There was no need to look at Yuji. His character and talent were guaranteed.
Nobara had experienced deep despair and powerlessness during this battle. These feelings would become her motivation to continuously grow stronger in the future. With this experience, she would surely be promoted to Grade 1 Jujutsu Sorcerer very soon.
What pleased Eichi the most was Megumi. After being unable to contend with Sukuna, his first thought was not to use Mahoraga for a suicide attack.
Instead, he put all his effort into successfully deploying his Domain Expansion.
A genius capable of fully using a Domain at fifteen years old! Even Satoru did not use Domain Expansion until he was seventeen.
"Is that a Domain?"
Ieiri Kiyotaka, beside Eichi, looked in surprise at the Domain that suddenly enveloped the juvenile detention center's dormitory building.
"Round Deer."
Eichi summoned Round Deer, then quickly walked toward the Domain.
"Kugisaki is already out. Remember to treat her injuries. Fushiguro is running low on Cursed Energy. I'll go get him out."
With that, Eichi directly invaded Megumi's Domain.
A Domain was usually a move used to trap enemies inside. Its resistance to external intrusion was very weak.
"Fushiguro!"
Ieiri Kiyotaka's eyes widened as he looked at the Domain before him in disbelief.
Being intelligent, he quickly guessed the Domain's caster from Eichi's tone.
That was why he was so shocked.
'To be able to use Domain Expansion at fifteen years old, Jujutsu Headquarters will surely be in an uproar again.'
Inside Chimera Shadow Garden, Sukuna's resistance was already becoming somewhat strained.
Losing his heart ultimately affected his combat power.
However, he was not in a hurry, because Megumi would run out of Cursed Energy and collapse before him.
Just as Megumi was contemplating whether to use Mahoraga, Yuji finally escaped the shadow of death and once again suppressed Sukuna back into his body.
"Round Deer!"
Noticing this, Megumi immediately stopped attacking and summoned Round Deer to treat Yuji's injuries.
'Damn it, it's not enough!'
Under the effect of the Domain, a second and third Round Deer were summoned by Megumi.
'After the Domain is released, I will fall into Cursed Technique burnout. I must heal Itadori Yuji before then.'
Megumi began to desperately squeeze out the Cursed Energy within him.
"Your use of Reverse Cursed Technique is too crude. Ordinary wounds are fine, but for treating internal organs and limbs, it needs to be more precise."
In the darkness, a large hand reached out and covered the wound on Yuji's chest.
Eichi was a professional at treating hearts. After all, he himself had lost a heart before.
"The anatomical differences between Shikigami and humans are vast, so Round Deer isn't actually good at treating humans. It relies entirely on a large output of Reverse Cursed Technique to achieve victory through sheer quantity, which is also why Round Deer consumes a huge amount of Cursed Energy.
"So, if you want to reduce Round Deer's Cursed Energy consumption, it's best to master Reverse Cursed Technique yourself, and then use your own experience to direct Round Deer in treating others."
Of course, if one's own Reverse Cursed Technique was more efficient than Round Deer's, they could actually do it themselves.
Unless there was a rejection reaction.
Just as blood transfusions required considering blood types, the Reverse Cursed Technique generated by different people's Cursed Energy also had subtle differences.
That was why Shoko needed to assist with medical knowledge.
Round Deer had a great advantage in this regard because its Reverse Cursed Technique was purer, and almost everyone's body could accept it.
"How do you feel?"
Eichi removed his hand. Yuji's chest wound had completely healed, and the Domain enveloping them also completely disappeared.
"Oh, it really healed. That's amazing."
Yuji excitedly touched his chest all over.
"Speaking of which, my hand also grew back. It's so magical. Can I learn this too?"
The big-hearted Yuji immediately forgot the recent danger, and little stars began to appear in his eyes.
"Reverse Cursed Technique is a way Cursed Energy operates. If you want to learn, I'll find you a teacher."
"That's great!"
Thump!
Looking at the excited Yuji, Eichi could not help but flick his head.
It sounded good. It was a good head, but his hand hurt a little. That skull was too hard!
"Don't be overly ambitious. First, become proficient in using Cursed Energy."
Eichi used to hate teachers lecturing him, but when he became a teacher, he found that doing so was actually a bit satisfying.
"Is Fushiguro alright?"
Yuji looked worriedly at Megumi, who was leaning against the wall, unconscious.
"He's fine. I've already healed his external injuries. Now he needs to rest for a while to alleviate his mental fatigue."
This was also why Eichi had been teasing Yuji here and was not in a hurry to leave.
"Huff, huff, Ieiri-senpai, please call for backup immediately."
Nobara, who had successfully escaped with Divine Dogs, immediately went to Ieiri Kiyotaka for help upon seeing him. Her two classmates were still in danger.
"Don't worry, a Special Grade Jujutsu Sorcerer has just arrived. Fushiguro and Itadori Yuji will definitely be fine."
Ieiri Kiyotaka first comforted the panting Nobara, then had Round Deer help treat her.
"Is that so? That's good."
Soon after, the three walked out of the juvenile detention center.
"Are you two alright?"
Nobara glanced at the bloodstain on Yuji's chest and asked worriedly.
"I'm fine. All the injuries have healed."
Feeling Nobara's concern, Yuji raised both hands and struck a bodybuilding pose.
"Are you Kugisaki?"
"I am."
Nobara did not shy away, boldly sizing up the Special Grade Jujutsu Sorcerer before her.
At this moment, if it were Kasumi, she would probably already be standing with her hands pressed to her pant seams, giving a solemn self-introduction.
"Here. This suits your Straw Doll Technique very well."
"Huh?"
Nobara looked speechlessly at the strangely shaped gun in front of her, unable to fathom its connection to the Straw Doll Technique.
"Your Cursed Technique requires a hammer, nails, and a straw doll, right? Look here..."
Eichi pointed to the exposed hammer of the pistol.
"This hammer can replace your small hammer, and we've made subtle modifications to the bullets based on the Straw Doll Technique's nails. This can reduce the wind-up of your Cursed Technique."
The Straw Doll Technique, as a Cursed Technique, was actually quite strong, but actions like throwing nails, aiming, and swinging a hammer resulted in an excessively long wind-up.
By using this modified pistol, the wind-up would be greatly reduced.
Moreover, because of the faster firing rate, the probability of enemies dodging would also be greatly reduced.
"It actually works!"
Nobara curiously fired a shot to the side, discovering that her Cursed Technique actually worked.
At this moment, Nobara could not help but sigh in her heart, thinking that Tokyo truly lived up to its reputation as a big city. Even its exorcism methods were so advanced. Indeed, leaving the countryside had been the right choice.
