Bang!

In a thunderstorm area in the country of grass, the hazy and gloomy sky was pierced by a thunderbolt, and the pale light split the black curtain in two.

Finally, it slashed at a demon-like figure in the rain.

"Finally... Finally..."

The horned monster roared in the sky, and the roar even drowned out the thunder and lightning.

Cracking sound!

There was a strange sound of bones dislocation, and with the movement of Xili stretching his body, his flesh, meridians, and bones all stretched.

The whole person slammed up, and his upright body stood still in the thunderous rain!

"Eighty percent at last!"

A majestic and deep voice sounded faintly!

It's as if some beast hidden in the mountains has awakened.

After being struck by lightning for a year, hundreds of days of lightning washing on the face, the cell activity has already increased to 70%.

However, Xili was not satisfied, but stayed for more than ten months.

Ordinary Thunder Body Simulation Cultivation Device cannot increase cell activity to more than seventy percent, but the Lightning Channeling Device produced by Uncle Snake is different.

Moreover, Xili had mastered the change in the nature of the thunder attribute chakra as early as a year ago.

Day after day, the use of thunder stimulates the body.

And the heavenly thunder quenching body!

Eighty percent is not the limit, but the next step is to get very slow.

The rate at which the body absorbs natural energy on its own also tends to stabilize.

When the cell activity was sixty, Orochimaru suggested that Xili carry out the seal of the Immortal Chakra, but Xili endured his heart and held back to eighty percent!

Now...

It's finally time for the next step of your practice!

The current Xili doesn't dare to say anything else, purely in terms of the speed of the physical body, only Thunder Shadow can keep up with the current ninja world!

Others?

It's all rubbish!!

"Yes, it's finally coming to this point."

Orochimaru gently clapped his palms and walked over, looking very satisfied.

The little fragrant phosphorus has also grown from a malnourished small bean dice to... After all, the soybean cube is not very old, and no matter how much you supplement your nutrients, you can't grow it fast.

But in the past year or so, her complexion has improved a lot.

Xiao Xiangpho approached quickly with an umbrella in her hand, tiptoeing to protect Xili from the rain.

"Now you can practice the Immortal Curse Seal, right?"

Xili didn't care about the rain that fell on his body at all, and he stared straight at Orochimaru and asked.

How long did he wait for this day?

How long has it been lightning striked?

Get up earlier than a chicken, and practice is more tiring than a cow.

Eat more than pigs and sleep later than dogs.

It's all worth it, the chakra diversion merges with the natural energy, and the seal is stored in the body to form the immortal curse seal!

The most staying power of the immortal mode!

Men should last the most!

With the enhancement of cellular activity, Xili's body has come infinitely close to the limits of the human body.

But that's not enough!!

Because he can't be considered an ordinary human being, the limit of human flesh is only his starting point!

The awakening of the Devil Fruit, the fusion of natural energy.

will bring a new step of physical breakthrough!

……

"It's time for the next experiment."

Orochimaru's Earth Curse Seal was almost perfected, and he was going to start his research on the Heavenly Curse Seal.

Before that, a prototype is needed to collect the relevant data.

That's the immortalized Xili!

And absorbing natural energy into the immortal mode is the first step.

The Immortal Curse Mark was also Orochimaru's original idea a year ago.

Usually, the body absorbs natural energy autonomously, and integrates physical energy and spiritual energy in a ratio of 1:1:1.

Then the seal is sealed in the spell seal, and when you want to use this power, you will break the seal.

It's the Immortal Curse Seal!

"The natural energy in this thunderstorm area is too violent and very unstable, so let's change places."

Orochimaru turned around and led the way, as if he was helping Xili improve his strength for free.

This is not the case.

It can be said that Xili and Orochimaru have a mutually beneficial relationship.

Sili wants to gain strength and become the strongest.

And Orochimaru needs Xili's immortal data to perfect his Earth Curse Seal, Heaven Curse Seal, and realize his ambitions!

……

A towering stone forest.

Sili landed cross-legged on a square plank, which was placed on a stone tree more than ten feet high.

To perceive the energy of nature requires being in a state of extreme stillness.

This extreme tranquility means that it is not affected by the outside world.

Of course, Xili does not need to perceive natural energy, because his physique is special, even if he is unconscious, his body will automatically absorb it.

If you change to consciously and actively absorb natural energy, the speed will be faster.

Now all Sili needs to do is speed it up.

After the senjutsu chakra was fused to a certain extent, it was stored and sealed on the forehead like Tsunade's Yin Seal.

The difference is that Tsunade's Yin Seal requires three years of accumulation, and the chakra is divided and stored little by little, and the Yin Seal will only appear after reaching a certain amount.

And Xili is not accumulated for a long time before the immortal curse mark appears.

He directly evolved the huge chakra of the main body into the immortal chakra, and then opened the immortal curse seal, and then sealed the immortal chakra that he usually did not use into it.

To put it simply, the Yin Seal is a pit that accumulates over time by relying on the principle of water drops and stone penetration, and the Yin Seal is developed after the pit expands to a certain extent.

The Immortal Curse Seal is to dig a pit first, and then accumulate the Immortal Chakra little by little.

"It's best to be able to combine the chakra of the whole body with natural energy, enter the state of immortalization, and then seal all these powers."

Orochimaru stood on top of a stone tree not far away and said with a serious expression.

As a teacher, Orochimaru is undoubtedly very qualified.

Even if he has an impure purpose.

In fact, Orochimaru was also a little nervous, after all, whether Xili could succeed or not would directly affect his next experiment with the Heavenly Curse Seal!

Xili nodded slightly, and sank into the absorption of natural energy with all his heart.

It doesn't matter if the natural energy absorption is less, but it won't form the Immortal Chakra, and the special physique of Xili will make the Chakra become violent.

But if you absorb too much natural energy, it will become a strange thing.

Like toads? Snake? Slugs?

Xili is not cultivating the immortal arts of the three holy lands, and the ghost knows what will become, maybe it will become a real minotaur.

So...

Orochimaru ignored his words directly, although he nodded in agreement on the surface, but in fact his left ear went in and out of his right ear.

The whole body chakra proportionally absorbs natural energy, and the immortal chakra that is fused is sealed.

It can only be said that the initial pit is a little bigger.

This pit can be slowly expanded through subsequent accumulation, and there is no need to risk it to become a little bigger.

Orochimaru said this just to collect more perfect experimental data.

Settle down, meditate.

Sili gradually got into the groove...

Seeing this scene, Orochimaru jumped off the stone tree with a decisive instantaneous technique, and the only thing he could do now was wait.

Regarding the Immortal Chakra, he can't help Xili.

However, he believed that Xili could overcome it, because the Alista clan were naturally close to nature and could easily feel the existence of natural energy.

……

However...

Will things really go that well?
