In Konoha, you get one evolution point every day.

When Tobirama Senju opened his eyes, he was already a mature female rabbit.

"Wait! Where am I?!" Tobirama Senju opened his eyes and found himself not in the Pure Land, but in a strange space... No, this place is not unfamiliar!

This is his home!

"Tsunade!!" Tobirama Senju tried to shout Tsunade's name.

Glug glug—

"Lin Fan, what's wrong with your rabbit?" Tsunade put the photo of Tobirama Senju back in the room, then pointed at the rabbit and asked.

"It's nothing, maybe he's just a little excited." Lin Fan had already seen Lin Xiaobai's change, which was definitely because Lin Xiaobai had summoned Tobirama Senju into his body.

"Ooh! You wicked brat! Let go of me!!" Tobirama Senju jumped out of Lin Fan's arms with a little force and landed, instinctively preparing to form hand seals, but Lin Xiaobai had no chakra, so Tobirama Senju's soul energy could not materialize.

To Tsunade, this scene appeared somewhat comical.

"Haha, this rabbit's doing hand seals? Did you teach it?"

"Haha, I guess so." Lin Fan was also amused by Tobirama Senju's behavior.

Even if Tobirama Senju wanted to perform hand seals, he would still need hands now, right?

"Damn it! Who is this man? Why can't Tsuna see me? Wait!" After saying this, Tobirama Senju finally snapped out of his daze, recovering from the surprise of being resurrected.

He looked down at his hands, and those unfamiliar and clumsy rabbit hands came into view.

He was reborn as a rabbit!

How could this be repaired?!

Tobirama Senju was furious! He had finally been resurrected from that deserted Pure Land and met Tsunade, only to be turned into a speechless rabbit!

Wait, just because I can't speak doesn't mean I can't write!

Tobirama Senju's mind works fast; he immediately used his claws to write on the floor.

A moment later, the uneven lettering emerged from the floor.

"I am Tobirama Senju, Tsuna, hurry up—"

As I write this, Tobirama Senju's soul flies out from the rabbit's body.

"How did I get out?!" Tobirama Senju's soul hovered in mid-air, looking at Tsunade and Lin Fan, filled with resentment: "I was about to finish writing!!!"

Tobirama Senju left.

Lin Xiaobai returns to his position.

"Huh, what am I doing here? Gurgle~~" Lin Xiaobai put down its paws, waved off the stone powder, licked its palms, and truly transformed back into the rabbit it should be.

And what about Tsunade?

When she saw the rabbit writing, she was initially surprised that Lin Fan would raise rabbits.

Upon seeing the six large characters "Senju Tobirama" and "Shonan" written by the rabbit, her expression suddenly changed.

"Second Grandfather!" Tsunade stared in disbelief at the words on the floor, then at Lin Xiaobai, and finally at Lin Fan, asking, "What exactly happened?"

Seeing Tsunade so excited, Lin Fan calmly waved his hand.

"It's nothing, I just discovered this rabbit's innate talent—she's actually the inheritor of the Heavenly Rank cultivation technique, Ghost Possession." Lin Fan said this nonsense with a straight face.

"Gurgle gurgle!! (I'm awesome, right!!)" Lin Xiaobai heard someone praising her, and she raised her head and gurgled.

"Heavenly-rank cultivation technique, possession by a ghost..." What kind of ghostly ninjutsu is that?

Tsunade shook her head.

That's not important. What's important is that this rabbit may have just called her great-grandfather down from the Pure Land!

"What's its name?" Tsunade picked up Lin Xiaobai, her eyes softening.

"Her name is Lin Xiaobai."

"Her?" Tsunade asked, puzzled. "Shouldn't it be it?"

Lin Fan shook his head: "When a creature can understand human language, it is no longer an animal."

"That's true." Tsunade nodded, as if she had never regarded slugs as animals but as companions.

"Come on, Shiro, transform again. Do you see this person?" Tsunade heartlessly grabbed the picture of Nawaki from the table, completely forgetting about her great-grandfather from before: "Could you call him down?"

"No." Lin Xiaobai shook her head to indicate her refusal.

Lin Xiaobai jumped out of Tsunade's arms, landed on the floor, and wrote: "I need to rest."

Seeing this, Tsunade didn't force Lin Xiaobai. Instead, she treated Lin Xiaobai like her own daughter and even wanted to bathe her, saying that when she saw Nawaki tomorrow, Nawaki would be clean and tidy. Lin Fan didn't stop Tsunade either, only asking that she not exhaust Lin Xiaobai, after all, this was a little bunny that he had "invested heavily in".

The next day, the rope tree came down and was completely bewildered to find that it had turned into a rabbit.

"Rope Tree, is that you? It's my older sister!"

"Sister? How did you get so big? And where am I?" Rope Tree uttered a bunch of gibberish, and it was only after Lin Fan asked Rope Tree to write that Rope Tree realized that she had possessed a rabbit.

After exchanging words for a while, Rope Tree's soul flew out, and both parties parted ways with satisfaction.

"Lin Fan, thank you." Tsunade rubbed her swollen eyes from crying.

"No need for thanks, we're family." Lin Fan waved his hand, noticing that Lin Xiaobai looked even more tired than yesterday, and said, "Xiaobai seems very tired. Let her rest well for a while."

Lin Fan hugged Lin Xiaobai and rubbed her rabbit ears.

"Yeah, and thank you too, Shiro. I'll take care of all your rabbit food from now on!" Tsunade patted her Mount Targon.

......

As a result, Lin Xiaobai's status rose accordingly, and he could practically do whatever he wanted within the Senju clan... Anyway, only Tsunade and Lin Fan lived in the clan now; the rest of the Senju clan members had all dispersed after the end of World War II.

With the new semester starting, Lin Fan also upgraded his "Language Evolution +3" to "Language Evolution +4": "You have basically mastered human language, you have begun to understand animal language, and even animals can generally understand you when you speak."

"Lin Fan, do you think I can become a human like you in the future?" Lin Xiaobai asked in Lin Fan's arms.

"Rabbit - Evolution +3": "Slightly increases intelligence, slightly increases physical quality, and doubles the duration of the summoner's soul possession."

Lin Fan was somewhat willing to part with Lin Bufan, after all, this rabbit's abilities seemed very promising.

"Of course." Lin Fan didn't know how long it would take for Lin Xiaobai to become human again, but judging from the progress of evolution, he estimated that it would be possible to achieve it in 6, 7, or 8.

It takes 7 to get 100 evolution points... which is 100 days. That's really too difficult.

correct!

It seems he never thought about the issue of lifespan.

It's no wonder Lin Fan hadn't thought of this.

The main thing is that I have plenty of physical strength and energy every day, and all my stats are as high as a bull's.

He doesn't look old.

So I never thought of it.

Lifespan: 1 years

Wow, there really is one!

evolution!

"Lifespan Evolution +1": "The vitality of your physical cells will not decline, meaning that as long as you do not suffer a major blow or die, your lifespan will basically not be reduced."

Huh? I've only evolved to level 1! And you're already immortal?

At the intersection on the way to school, Lin Fan stared blankly at the panel for a moment.

However, upon closer reflection, it seems that all these evolutions of the system are tied to existing circumstances.

"So, because my physical strength, internal organs, and blood have all been improved, my lifespan has become a fixed state?"

While this is a form of immortality, no one can say for sure whether they will suffer fatal injuries in the future...

Looking at the evolution points left after spending three months of summer vacation.

Evolution Point: 1

Lin Fan smiled.

Evolution points are just not enough!
