One night, Shintaro suddenly recalled his past life and the reason he came to this world.
"The uncontrolled infinity is what brought me to another world."
Then he discovered the cause of his amnesia, which was the damage to his soul during the cross-world journey.
The memory recovery now must be due to the healing of his soul wounds.
"If that's the case..."
He remembered something and immediately extended his hand.
Like a conditioned reflex, his brain executed a technique from his previous life, the Limitless Technique.
Shintaro went to the bathroom, stood under the shower, and turned on the water valve, letting the water flow down.
Droplets of water gathered in the air around him and slid down but could not touch him at all.
"Sure enough, Infinity can be used in this world!"
Shintaro couldn't help but feel a bit excited. After all, this was what he relied on in his previous life.
Even in this world, Infinity would surely become one of the strongest abilities.
The principle of Infinity was extremely complex, and even the Gojo family members could only explain part of it superficially.
Shintaro's understanding of Infinity in his previous life was relatively shallow.
He only knew that its normal use was for stopping power, attraction, and repulsion.
However, at the ninja school, Shintaro learned mathematics and understood the concept of Infinity in a mathematical sense, giving him a clearer understanding of Infinity than in his previous life.
Infinity itself could make all objects close to it converge infinitely without actually touching it.
The speed of an object trying to touch itself would slow down until it stopped.
This is where the stopping power comes from.
By enhancing this tendency of getting closer, he could achieve negative infinity, thus creating a strong attraction.
This is the origin of Blue.
Red is a bit more complicated.
To master it, he had to learn the Reverse Cursed Technique first.
These two seemingly similar things are actually not the same type at all.
Cursed Energy is generated by negative emotions such as resentment and sadness, so it is a type of negative energy.
This negative energy can be used to produce various effects, but it cannot be used to heal injuries. Healing injuries contradicts the nature of negative energy.
Therefore, it is necessary to transform negative energy into positive energy in a way similar to negative-to-positive conversion. This operation is called the Reverse Cursed Technique.
This is why the Reverse Cursed Technique can heal injuries.
It sounds very simple, but in reality, it is so difficult that very few people master it.
And by injecting the positive energy generated by the Reverse Cursed Technique into the innate Technique, the effect of Red can be obtained.
Red transforms infinite negative energy into infinite positive energy.
The effect changes from attraction to repulsion.
After testing, Shintaro successfully used the Limitless Technique in this world.
However, this was limited to basic usage, and he could not yet use Blue or Red.
But he was quite satisfied. At least he was stronger in this life compared to when he was the same age in his previous life.
Shintaro then returned to bed and continued sleeping.

The next day.
Shikaku appeared at Shintaro's house early in the morning.
Shintaro had just finished washing and opened the door after noticing him.
Shikaku's hand was hanging by the door, then he put it down and smiled, saying, "We have a mission today. We will meet at the village entrance in half an hour."
Shintaro immediately agreed, and Shikaku turned and left.
After he closed the door, Shikaku turned and stopped. Shintaro opened the door again and asked, "Is there something else?"
Shikaku shook his head and left.
'Indeed, this child is very sharp. Does it have something to do with his eyes? They are suitable for this mission.'
Half an hour later, at the Konoha gate.
Shikaku said to Shintaro, Kurenai, and Asuma, "This mission is to go to the Land of Waves to survey the terrain. It's a task from the geologists of the Land of Fire."
"The mission level is C. Coincidentally, I have some free time this time, so I'll go with you."
Asuma crossed his arms and joked, "I almost forgot that we have a teacher."
Shikaku waved his hand and said, "Don't blame me. I was very busy before, not because of the missions your father gave me."
"Go and say some good words to your father later and give me fewer tasks."
"I'm happy to do these low-level boring tasks with you all. At least I won't be in danger. I don't want my wife to become a widow."
Asuma didn't seem to have a good relationship with his father, so he didn't respond to Shikaku's words.
Kurenai broke the current silence and said expectantly, "What is the Land of Waves like? This is my first time going abroad for a mission!"
"It's just a small island. It's been isolated overseas for a long time and is very poor." Shikaku answered honestly.
This made Kurenai complain disappointedly, "Well, that geologist is really boring. What needs to be investigated in such a country?"
Shikaku explained seriously, "That's why it's only a C-level mission. If we were to survey the Land of Fire, it might take several years. That would definitely be an A-level mission."
Kurenai nodded, having no expectations for this mission.
However, some doubts arose in Shintaro's heart.
He didn't quite believe what Shikaku said.
From the fact that Shikaku found them this morning, this mission wasn't easy.
If it were just a simple C-level mission, he wouldn't have called them all in the morning due to his lazy personality.
Moreover, a Jonin is very valuable when a local war breaks out. How could he accompany them to a small country to complete such a boring task?
'There must be something hidden here.'

At the same time, on the coast of the Land of Waves, a small boat had just docked.
Four people disembarked from the boat, three men and one woman, and the girl was clearly still young.
The girl had beautiful reddish-brown long hair, green eyes, and looked very sweet.
But the three men seemed to respect the girl.
The girl stretched, then turned around and said, "Ao, I'm going to play for a bit."
Before the Jonin named Ao could answer, the two brown-haired ninjas beside him extended their hands to stop her: "Miss, this place is not as safe as in the village."
The girl frowned and said, "What danger could there be? Now this island is full of our people, could it be that I could still be kidnapped by Konoha?"
"It's not impossible to tie me up, as long as a handsome guy comes to tie me up."
The two ninjas wanted to say something, but the girl shook her head, her long hair fluttering back.
"Okay, okay, I won't run too far." After saying that, the girl took off and ran, leaving the three of them.
The Jonin named Ao had short blue hair that was tied up, and earring-like talismans hanging from his ears.
The forehead protector on his forehead was very different from Konoha's forehead protectors, with four wavy lines symbolizing water mist.
That was the emblem of Kirigakure Village in the Land of Water.
