The so-called Reversal technique.
It is a manipulation of Cursed Energy.
Cursed Energy itself is a negative power; it can strengthen the body, but it cannot cause it to regenerate.
Therefore, by operating Cursed Energy in a multiplicative form—where a negative times a negative equals a positive—the negative Cursed Energy is transformed into positive energy, thereby achieving the effect of rapidly regenerating injured limbs.
It can be said that once this is mastered, as long as one is not killed in a single blow and Cursed Energy has not been exhausted, one is almost an immortal existence.
Furthermore, this operation is not limited to oneself alone.
Gojo was very clear about how massive of a boost this technique provided for him.
However.
Now is not the time to dwell on this.
There is still a "protagonist" over there waiting for him to explore.
Gojo strode toward the boy in sportswear.
"Hey, newcomer, what are you standing there like a fool for? Were you scared silly by this place..."
Gojo said to him with a smile, his tone carrying a hint of mockery.
However, before he could finish speaking, he saw the boy suddenly clench his fists and pull them tightly to his sides at his waist.
Without caring about the fact that they were in a crowded plaza, he shouted excitedly.
"Could this be the so-called otherworld summoning?"
Following the boy's sudden shout, the people around them subconsciously looked toward him.
Upon seeing this strangely dressed boy shouting excitedly.
Both humans and demi-humans tacitly kept their distance.
It was as if normal people had encountered a madman on the street.
"Clap, clap, clap!"
Just as the people around them moved away, a crisp sound of applause rang out.
"Not bad, kid, you've got a lot of spirit!"
Gojo applauded, smiling as he said this to Subaru.
"Eh?"
Subaru didn't have much of a reaction to his own actions just now or the response of the people around him.
But he was stunned when he saw the handsome figure in front of him, wearing a sharp, fitted uniform, with white hair and Sunglasses, walking towards him.
"Wait."
"Your... your outfit."
Subaru carefully examined Gojo's attire and said, feeling a bit unsure.
"Isn't this outfit of yours a bit too off?"
"Sunglasses with white hair—could it be that you were also summoned to this otherworld?"
"I'll give you credit for having some insight."
Gojo reached up and pushed his Sunglasses up, his ice-blue eyes flashing in the sunlight, his tone casual and open. "Gojo, an outsider like you who accidentally stumbled into this strange world."
"Oh!!!"
"It's just like what they say in light novels,"
"We must be the heroes, the teammates destined to save this world from the Demon King, right?!"
Having just transmigrated, Subaru was quite excited to meet someone with the same status as himself.
"Well, if you want to put it that way, I suppose that's not impossible."
"But if we want to be more accurate,"
"You are here to support me."
Gojo said this, a hint of a smile in his eyes beneath his Sunglasses.
"Support?"
Subaru was stunned.
"Yes, support."
Gojo pointed at himself. "protagonist."
Then he pointed at Subaru. "supporting character."
"You can just understand it like that."
"I'm a supporting character?"
"Of course~"
"Otherwise, why would you think I'd be waiting here for you?"
Gojo said with a confident tone, looking very sincere.
"So that's how it is."
Although he wasn't any kind of protagonist, this was an otherworld, after all, not some dull and boring modern life.
Even if it was just as a supporting character, it would still be very interesting.
Under Gojo's explanation, Subaru didn't dwell on the issue of his status and quickly accepted the premise he had provided.
"Right, I haven't introduced myself yet. My name is Subaru, I'm seventeen years old."
"What are we doing now?"
"Are we continuing to wait here for other teammates, or going to kill monsters and level up or something?"
Watching Subaru's eager appearance, Gojo rubbed his chin and suddenly leaned in close to him.
"W-what is it?"
Gojo's sudden proximity made Subaru tilt his head back slightly.
From such a close distance, Subaru could clearly see, from the edge of the Sunglasses, that pair of blue eyes that were more beautiful than gemstones.
"As my partner, have you felt anything different since you transmigrated here?"
"For example, a skill panel in your head, or some superpower like being able to conjure things out of thin air?"
Gojo draped an arm around Subaru's shoulder, acting very familiar.
"Panel? Superpowers?"
Subaru closed his eyes and pondered carefully for a long time, but didn't come up with anything.
He could only shake his head with a disappointed look, his tone filled with dejection.
"It seems like there's nothing."
"What about physical strength, has it increased, or has your speed become faster?"
Subaru waved his arms, gesturing, and then said dejectedly, "It seems like there isn't that either."
"Is that so."
Gojo nodded thoughtfully, then patted his shoulder to console him. "It's okay, maybe you just haven't discovered it yet, or the conditions haven't been triggered."
"Right, that's true."
"Let's go!"
"Where to?"
"Are we going to start our thrilling adventure?"
"Are we going to take some low-level quests first to farm experience and gold to buy equipment?"
"I'm actually quite confident in my arm strength!"
"Of course not. To celebrate your arrival, we're going to eat dessert!"
Gojo said with a smile and, amidst Subaru's stunned expression, draped his arm around his shoulder and headed off into the distance.
Before long, the two appeared at the cake shop where Gojo had spent money yesterday.
At a small table in the shop, each of them had a berry cake placed in front of them.
"Hurry up and try it; the cakes here taste really good."
"Oh, oh."
Subaru picked up a small spoon, dug out a piece of cake, and stuffed it into his mouth.
His expression was a bit strange.
Although, he had already transmigrated, so there was nothing he couldn't accept.
But... this development was really not quite the same as he had imagined; light novels aren't like this.
Gojo watched Subaru, who seemed a bit absent-minded, and said with a chuckle.
"Subaru, is it okay to call you that?"
"Of course."
"Speaking of which, were you still in school before you transmigrated to this otherworld?"
Subaru hesitated for a moment and shook his head. "No, for some reasons, I had taken a leave of absence from high school and was staying at home."
"Then we're quite similar."
Gojo, who was still attending Jujutsu High, said with a smile.
"I was in Tokyo before, where were you..."
