After a while, Uzumaki Rin rubbed his forehead. Only then did he fully digest all the information the System had transmitted to him.
This System was called the Super Fusion System. Simply put, it allowed him to fuse with all kinds of things. According to its description, even abstract concepts like time could be fused.
Of course, that was only possible if the host was extremely powerful. Otherwise, if you couldn't even obtain fragments of time, how could you possibly fuse them?
Moreover, this fusion wasn't a simple combination. Instead, it extracted the strengths of the fused object and integrated them into the host. Otherwise, if you fused with a rock and turned into a rock yourself, what would be the point?
Rin picked up a teacup and silently activated Fusion Scan.
"Scan complete. Fusing with this item can enhance the toughness and strength of fibrous materials within the host's body."
After seeing the result, Rin put the teacup down.
For his first fusion, he couldn't be careless. While fusion itself wasn't a problem, if he wanted to fuse another item afterward, he would first have to fully develop the ability gained from the previous fusion to 100%.
For example, fusing with this wooden teacup would increase the toughness and strength of his body's fibrous materials, but that enhancement wouldn't reach perfection immediately. Only after he refined that ability to its peak could he proceed with the next fusion.
"System, scan this for fusion." Rin picked up a kunai.
"Scan complete. Fusing with this item can enhance the host's bone strength, cell wall strength, and overall power."
Rin wasn't satisfied. He put the kunai down and continued scanning other objects.
For the next half hour, he scanned everything in the room, but still couldn't find anything suitable to fuse with.
Then, his gaze landed on a potted plant.
The bonsai was made from the branch of a long-lived tree. This type of tree could survive for an extremely long time and possessed remarkable vitality. Even when turned into a bonsai and kept in water, as long as the water was changed occasionally, it would rarely die.
When Rin saw it, an idea immediately came to mind.
Could he fuse with the branch of this tree?
"System, perform a fusion scan on this." Rin took a small branch from the bonsai and scanned it.
"Scan complete. Special ability detected: Photosynthesis. Fusing with this item can enhance the host's vitality, increase cellular division frequency, strengthen the immune system, and grant the special ability of Photosynthesis."
Rin froze.
Photosynthesis? What kind of ability is that? Am I supposed to plant myself in the ground and wait to sprout?
"System, what will happen if I fuse this Photosynthesis ability into myself?" Rin asked.
"Unknown prior to fusion."
Rin fell silent. So basically… all consequences were his own responsibility.
Looking at the branch in his hand, he fell into deep thought. After searching for so long, this was the only item with a special ability—and even aside from that, its fusion benefits were quite good.
But what if he ended up like those White Zetsu? He definitely didn't want his appearance to change into something like a pitcher plant.
"System, will my appearance change after fusion?"
"No. Neither internal organs nor external appearance will change. The host will only gain the abilities of the fused item. If the host has special requirements, the System can also modify fusion rules."
"…No need for that. In that case… I'll fuse it."
After thinking it through, Rin made his decision.
"Fusion target confirmed. Beginning fusion."
In the next instant, the branch in his hand disappeared. At the same time, a warm current surged through his body, making him feel completely relaxed and comfortable.
Rin could clearly sense that the already vitality-rich cells of the Uzumaki clan were surging with life energy once again. A faint green glow even appeared around his body—an obvious sign of excessive vitality overflowing outward.
At the same time, the bonsai beside him began to change. The branch of the long-lived tree started growing rapidly, sprouting countless new shoots at a speed visible to the naked eye, eventually bursting through the flowerpot.
Seeing this, Rin was speechless.
What the hell is this? Even if it boosts vitality, it shouldn't explode to this extent, right?
As Rin's life force surged outward, Jiraiya outside sensed it as well.
"Wood… Wood Release?!"
The moment Jiraiya pushed open the door and saw the scene inside, he was completely stunned.
By now, the long-lived tree had grown into a lush small tree under the support of that overwhelming vitality. If it were capable of blooming, the entire room would likely have been filled with fragrance.
"What's going on here?" Jiraiya asked blankly.
"I don't know either. I was just refining chakra, and then a warm current suddenly surged through my body. After that, I felt really comfortable… and then it turned into this," Rin said with an innocent expression, as if it had nothing to do with him.
After three years of practice, his acting skills had reached perfection. Forget Best Actor—he was now performing entirely on instinct.
After hearing Rin's explanation, Jiraiya carefully examined him.
What he saw shocked him.
Even though the fusion had already completed, the dense life energy within Rin's body was still continuously radiating outward.
Even compared to Kushina's vitality, it was on a completely different level. Jiraiya didn't even need to bite him—just standing near Rin made him feel refreshed, as if even his old injuries were healing.
But Jiraiya wasn't thinking about that right now.
He was worried whether this situation might harm Rin's body.
Under normal circumstances, such an overwhelming release of life force would mean that the body was over-consuming its own vitality. Once that life energy was exhausted, death would follow.
"Come on, we're going to Tsunade."
After thinking for a while without reaching a conclusion, Jiraiya immediately grabbed Rin and vanished with the Body Flicker Technique, heading straight for Tsunade.
If something had truly gone wrong with Rin, then Tsunade was the only one who could save him.
When Tsunade saw Rin's condition, she was equally shocked and immediately began examining him.
But after a long inspection, she found nothing wrong.
Not only were all his indicators normal—they were over ten times stronger than those of an average person. He was so healthy it was almost absurd.
"Tsunade, what's wrong with Rin?" Jiraiya asked anxiously when he saw her frowning in silence.
Tsunade looked at Rin, then said to Jiraiya:
"In this situation… there's only one explanation."
"His Sage Body Public belief has awakened."
