"Eat, eat......" Sakura Haruno was startled, "Wait, shouldn't it be a joint transformation technique?"

The joint transformation technique can merge two creatures with chakra into one, which is considered a relatively unpopular ninjutsu, but Sakura can often see others use a trick: Sasuke's demon form, the combination of Naruto and Toad, and even the dried persimmon oni shark he fought a few weeks ago, he actually merged with a knife.

The joint transformation can merge the advantages of both sides, and theoretically Sakura Haruno can also transform with the slug, but she never considered this - does the slug have any advantages, other than its large size?

However, as soon as Slug said this, she suddenly found that this trick seemed to be feasible for the cultivation of immortal arts?

"Hehe, it's still different from the Combined Transformation Technique. Slug shook his tentacles with a smile and said, "You rarely use this kind of transformation technique, you don't know enough about it, do you?" Combined transformation can combine the 'characteristics' of both sides, but the essence of my ability to use immortal magic is an experience and perception gained after learning, not my own inherent trait...... So even if we merge, you won't be able to use immortal arts. ”

"Besides, Tsunade and you have never been combined with me, and you have also considered the image of the joint transformation, right?"

"Uh......" Sakura Haruno's face froze, and she had to admit that it had a point.

It's really not that I dislike my own psychic beast, the slug looks a bit like jelly on the outside, it's not ugly, and I think it's cute when I get used to it, but it's another thing to transform into a slug together-

Imagine the dark green, translucent Haruno soft and chubby soaky cherry blossoms.

Although she has followed the way of thinking that has not changed since her previous life, she believes that strength is the most important thing, and the rest of the beauty and ugliness issues can be ignored, no matter what, she will not follow the typical little girl like Ino, who regards beauty as the first place, but if a ninjutsu will make her ugly and unable to look at it directly, then there is basically no improvement in her strength......

Then she would never be interested in using it.

Ugly rejection!

"Just like toad oil, when I am in my body, I can channel natural energy into your body, thus helping you quickly perceive the presence of natural energy. Slug patiently explained, "So, let me swallow you!"

"Before that, take off your clothes. Because I need direct contact with your skin. ”

Sakura Haruno always felt that a strange smile seemed to appear on the little slug's expressionless face.

"Uh......" she hesitated for a moment before she stopped dwelling, "Okay." ”

After all, there are no outsiders here, only a slug immortal is here, and in order to cultivate, no matter how much sacrifice you make, there is no need to be pretentious about a trivial matter.

Then again, slugs are hermaphroditic...... It can also be said that there is no gender.

That way it won't be embarrassing.

In short, the cultivation method of the Slug Immortal looked strange, but the effect was indeed quite significant.

The first time she was swallowed by a slug, she began to channel natural energy, and Sakura Haruno had a distinct feeling - a strange energy from the outside world poured into her body like a tide, and she felt the presence of natural energy for the first time in her life!

This huge energy is originally diffused in nature, like nitrogen in the air, and the reserves are huge, but it is not perceived by humans, and the function of the slug is to give this energy a "taste" or something, purify it, collect it, and then pour it into the body of the spring no cherry tree, and then the spring no cherry tree perceives something......

It was as if the door to a new world had been opened.

The experience of getting a new feeling is very indescribable.

For example, because of the defect in the evolution of the human eyeball, there is a blind spot in the human field of vision, that is, if you print a photograph of what you see with your left eye, then there is a permanent area on the picture that is not patterned...... But people don't realize it. Natural energy is actually a "blind spot" in human perception.

And the Sakura Haruno lying in the slug's body, at this moment, it was like color blindness suddenly returning to normal, the blind spot suddenly disappeared, and the world in her eyes suddenly became rich and complete!

"Is this what natural energy feels like?" Sakura muttered to herself.

Endless natural energy kept pouring in, and Sakura Haruno was intoxicated by this wonderful feeling of gaining new perception, and she lost her mind for a while-

"Sakura-sama Haruno, what are you stunned about?" Seeing this, the little slug hurriedly shouted loudly, "Quickly control the natural energy, don't forget what I told you just now!"

Its reminder came a little too late.

Being reminded by the slug so loudly, Sakura Haruno was a spirit, and finally came back to her senses from that wonderful perception, and then realized that she was still in a dangerous cultivation!

Natural energy is not a harmless thing.

Sakura Haruno can already feel that it is eroding her body!

"Hmph...... Damn, we need to get it under control!"

She gritted her teeth, her mind racing wildly, desperately recalling what Slug had introduced about natural energy earlier.

“…… Remember, spiritual energy, physical energy, and natural energy must be fused precisely in a one-to-one configuration to form a perfect balance in order to learn the immortal chakra that can be controlled by people!"

"On the other hand, if the natural energy is not well controlled and you inhale too much, you will be 'naturalized', that is, ...... I'm going to die!"

- That's what Slug said before.

"Is there an exact ratio of 1:1:1......? This thing is so hard to control!"

For her own spiritual energy and physical energy, Haruno Sakura's control power is estimated to rank first in the entire ninja world, and it is easy to manipulate it like a finger and move freely, but the unfamiliar natural energy, because it comes from the outside world, is extremely difficult to control!

Sakura Haruno's brows tightened.

Although she was inside the slug, she seemed to clearly feel the cold sweat on her forehead.

The natural energy poured in too much, too fast, and she felt like she was maneuvering a high-speed truck on a rampage on the road, threatening to rush off the side of the road, crash into a hard boulder, and crash in an instant!

The most terrifying thing is that not only did the truck not brake, but the accelerator was also locked, and it was accelerating wildly!

The crazy influx of energy continued to accumulate in Sakura's body, and soon reached a certain critical point-

"I can't control it!"

In a matter of seconds, the natural energy was completely out of control!

Sakura Haruno's eyes widened suddenly, and then the next second-

Burst!

She was spit out by the slug.

"Ahem, ahem!" the girl was covered in mucus, lying on the back of the slug immortal and coughing weakly, and it took a while for her breath to regain her breath and say, "Whew...... The first time it failed. ”

"It's normal to fail the first time. Even Lord Pillar had practiced many times before he succeeded. The little slug slowly moved over, walked up to her and said, "I didn't expect you to hold on for a few seconds!"

Sakura Haruno shook her head and smiled slightly.

"Don't comfort me...... I know I made a serious mistake just now. The first time I felt the energy of nature, I was stunned for a moment. Not next time. ”

The girl calmly admitted her mistake. She stood up weakly, leaned on the slug, washed away the slimy liquid from her body with water, and looked down at her hands and body.

"Is this what is called 'naturalization'?"

Her hands and feet underwent abnormal changes: the flesh became transparent, and through the flesh, the bones in her body were blurred and visible, and it was very permeable. And the muscle curves that were originally soft also fell softly, and dark green streaks faintly appeared on the skin.

In short, the whole person has a tendency to turn into a small slug.

As soon as she thought that she was turning into a slug that was one meter and six long, Sakura Haruno suddenly stirred up her whole body, the picture was too beautiful, she didn't dare to look at it at all! Fortunately, as the natural energy was extracted by the small slug, the mutation of Sakura's body was rapidly disappearing, and the soft flesh also regained the sense of muscle power.

"That's right," replied the slug, "if you absorb too much natural energy and can't control it, your body will undergo irreversible changes, and eventually you will lose consciousness and become a small slug in my body......"

"The loser who undergoes this change ends up irreversibly losing the ability to think, so you can also think—"

"They're dead. ”

Sakura Haruno frowned: "If that's the case, there should be other slugs in the Wet Bone Forest, right?"

The little slug shook its tentacles.

"Sakura-sama Haruno, you're thinking wrong......" it said slowly as it stared into Sakura's eyes.

"After a person who fails to cultivate becomes a slug, he will be fused into my body, that is, a slug immortal, and die forever......"

"Finally become part of the slugs immortals. ”

The voice of the little slug is cold.
