Naruto: My version is ahead of the ninja world

These snakes in Ryuchi Cave, regardless of size or status, all seem to enjoy biting people.

The intense stinging sensation caused Yu Xian's thoughts to disconnect once again.

Putting aside Yu Gen's current predicament, Ryuchi Cave is far more brutal than Mount Myoboku in its treatment of cultivators of sage arts. The toads of Mount Myoboku provide one-on-one guidance, while Ryuchi Cave's educational method is "self-reliance and self-destruction."

Dragon Cave will directly inject an excessive amount of natural energy into the practitioner's body. If the practitioner can withstand it, it means that he or she has the aptitude to cultivate immortal arts. Otherwise, he or she will have to try again in his or her next life.

In this "dream," the way the White Snake Immortal treats Yu Xian is somewhat unusual, but not that unusual.

The White Snake Immortal believed that Yu Xian's aptitude was simply insufficient to withstand natural energy, so it did not take the usual approach—injecting into Yu Xian's body not natural energy, but its snake blood.

Think about the physical changes that occurred after Kabuto Yakushi actively infused Orochimaru's blood. Keep in mind that was just Orochimaru, while now Hagen is being injected with the blood of the White Snake Sage, a thousand-year-old snake whose purity is off the charts.

The excruciating pain, beyond the limits of his physical and mental endurance, prevented Yu Xian from even uttering a wail. He gritted his teeth, feeling as if every cell in his body was being burned and torn apart.

To make matters worse, for some reason, the more pain Yugen was in, the clearer her consciousness became.

Death seemed imminent. Yu Xian felt his body undergoing some kind of intense change, and at that moment, he couldn't be sure whether this change was positive or negative.

We need to think of a way...

Yu Xian's mind became increasingly active, and suddenly he seemed to realize something... The next moment, whether it was the instinct hidden in the snake blood or the knowledge he had just learned from Orochimaru's research lab that surfaced in his mind, he didn't know.

In short, the instinct for survival prompted him to clasp his hands together, forming an unusual mudra.

As Yugen mobilized his chakra, his cells began to divide at an accelerated pace, attempting to gradually adapt to the power within his body through rapid metabolism.

On the surface, Yu Xian, who was lying on the ground, was shedding his skin like a snake.

At the same time, a system notification popped up in front of Yu Xian.

"Warning, you are now in a special storyline—Snake Shedding."

"You have exceeded the planned progress and come into contact with the fundamental power of the world."

"Your chakra spirit body is being eroded and evolved..."

Note: The snake represents the dragon on its journey, and the dragon represents the snake at the destination...

What is primordial power? Is it a power that has always existed in the world? Is it natural energy?

This is a riddle, but it's a riddle that's not clever at all.

Amidst the excruciating pain, Yu Xuan's thoughts flashed by. As his chakra continued to deplete, he could no longer maintain his original state of clarity.

After a while, he finally lost consciousness completely.

…………

He didn't know how much time had passed when the sound of rain reached Yu Xian's ears. He suddenly woke up and found himself in the tree hole he had been in before.

"Phew, I'm alive again."

This dungeon experience was unusual; both entering and leaving the dungeon were somewhat inexplicable.

The intense pain he had just experienced still seemed to linger in Yu Xian's body, so after waking up, he first checked his body. Only after discovering that he still had two hands and two feet and had not turned into a snake after receiving the White Snake Immortal's snake blood did he breathe a sigh of relief.

The weather outside was gloomy, and he couldn't accurately judge the time.

"Calm down and sort out what happened at the end of the dungeon."

"First, I moved from Konoha Village to Ryuchi Cave... Just how large is the area of ​​this so-called dungeon? Is it not limited to just Konoha Village?"

"The boundaries of the copy are worth exploring."

"Secondly, the White Snake Sage of Ryuchi Cave injected snake blood into my body. I myself do not possess the aptitude to learn sage techniques, and I cannot even sense natural energy, so the White Snake Sage used snake blood to modify my body..."

"Was this modification successful?"

"My appearance in reality hasn't changed much. Is it because I didn't kill the White Snake Immortal, so I couldn't gain experience points? After leaving the dungeon, everything I experienced there was automatically reset?"

Yu Xian checked the dungeon cooldown time and found that it was the normal seven days instead of double, which meant that he did not die unexpectedly in the dungeon, but the dungeon duration ended later.

"No, there was a special system message notification, so it shouldn't be a regular reset."

"The 'me' in the instance is certainly not my physical body. According to the instance's hints, it should be called 'Chakra Spirit Body.' So, the blood of the White Snake Sage caused the change in my Chakra Spirit Body?"

"To extend this further, does all the enhancement I received in the instance also apply to this spiritual entity?"

"Chakra is such a mysterious thing, it has at least the duality of reality and illusion, and it seems that we can't figure it out for the time being... At least Orochimaru was able to revive himself by using chakra."

Basic research on chakra was a topic that Yu Xian couldn't understand in a short time, so he temporarily abandoned his thoughts on it... At this moment, he only wanted to figure out the changes in his own body.

"Don't overcomplicate things. Just start with the surface. The White Snake Sage is on the same level as the Great Toad Sage of Mount Myōboku. He is at least a veteran sage who has lived for thousands of years."

"After absorbing its immortal blood, my body underwent some kind of change, and the most likely direction of this change is easy to guess... I can now sense natural energy?"

Yu Xian calmed himself down and immediately began to activate his senses, carefully sensing his surroundings. After a quarter of an hour, he finally sensed a special energy fluctuation around him, which penetrated his skin and entered his body.

"I really felt it, is this natural energy?"

Yu Xian's ordeal with the white snake in Ryuchi Cave wasn't in vain.

"Could it be that I'll be the first to experience the ninja world's beauty and makeup versions?"

Yu Xian immediately thought of immortal masks and immortal modes from the natural energy, but his excitement only lasted for a moment before he calmed down.

Being able to sense and even utilize natural energy is quite different from being able to enter a celestial state.

Of course, things aren't that simple. Entering Sage Mode requires a balance of physical energy, mental energy, and natural energy—a very delicate process. Jiraiya trained for decades and still didn't fully master it; how could Hagen possibly achieve something so easily?

Too little natural energy will prevent one from entering Sage Mode, while absorbing too much natural energy will lead to petrification or berserk state...

After carefully observing the changes in her body, Yu Xian finally understood what exactly had changed about her.

He certainly cannot enter Sage Mode. The changes on his body should actually be called Sage Transformation, Cursed Seal Transformation, or a more accurate term—Jugo Transformation.

Jugo possesses a naturally born Sage Body, which, according to his description, is a special ability of the people in his village. Later, based on Orochimaru's research, he believed that the source of this power was in Ryuchi Cave...

Regardless of the accuracy of Orochimaru's research, Jugo at least possesses the ability to absorb natural energy anytime, anywhere. Excessive natural energy can even cause him to lose control and go berserk.

In some ways, Yugen's situation is similar to Jugo's at this time. However, because it is an acquired modification, and a modification at the level of chakra spirit body, his body cannot change as drastically as Jugo's.

But it's also possible that because of this layer, Yu Xian's absorption of natural energy is controlled, and he can interrupt the process at any time...

Yu Xian began to try to see how much natural energy she could absorb.
