A God of Death in Konoha Village

Uchiha Madara held a small transparent bottle in his hand, filled with milky white liquid.

"What is this?" Kurosaki Ichigo asked curiously as he stood up.

Uchiha Madara knocked on the bottle on his hand: "This is oil extracted from the branches of a tree called Iron Immortal Wood. It can help you quickly sense natural energy."

Kurosaki Ichigo looked at him suspiciously: "Are you sure this thing is useful?"

"Of course there is no problem." Uchiha Madara said confidently, "I am afraid that the only one in the world who has truly mastered the sage mode is Hashirama, so I asked him to help me get something that can speed up the perception of natural energy."

Kurosaki Ichigo nodded reluctantly: "Then... okay... just how to use this thing?"

Hearing this, a smile appeared on Uchiha Madara's face: "You have to know that extracting senjutsu chakra to practice sage mode is very dangerous."

"Is it dangerous?" Kurosaki Ichigo recalled what happened before, and his heart suddenly moved, remembering that familiar feeling.

"Of course," Uchiha Madara said matter-of-factly, "otherwise, why do you think only Hashirama can use Sage Mode in this world?"

As he spoke, he continued to explain: "According to Hashirama, when refining senjutsu chakra, the intake of natural energy must be strictly controlled, otherwise extremely serious consequences will occur."

"What consequences?" Kurosaki Ichigo raised his eyebrows, looking a little casual.

It wasn't that he was too conceited, but that he finally remembered where that familiar feeling came from.

Although several years had passed, Kurosaki Ichigo quickly remembered that those natural energies felt exactly the same as those of Reiko.

Obviously, the so-called natural energy is the spirit child in his original world, but this world has developed a unique power model, so the ninjas who should not be able to sense the spirit child can control the spirit child in the sage mode.

Seeing Kurosaki Ichigo's distracted look, Uchiha Madara unhappily took out a [-]-centimeter-long pitch black wooden stick from his arms and hit him on the head with a snap.

"Ah" Kurosaki Ichigo shouted, and then glared at Madara Uchiha, "What are you doing?"

Uchiha Madara shook the stick: "Don't underestimate the danger of practicing Sage Mode. Once you show signs of mutation, I will use this stick to beat out the excess natural energy in your body."

"Fight it out." Kurosaki Ichigo glanced at the shiny wooden stick, "I always feel that what you said is unreliable."

"Stop talking nonsense." Uchiha Madara waved his hand casually.

Of course, Kurosaki Ichigo couldn't defeat Madara Uchiha, not to mention that after understanding the nature of natural energy, he was eager to practice the sage mode.

In this way, after several days of preparation, the two came to the training ground again.

Kurosaki Ichigo sat down cross-legged, while Uchiha Madara stood in front of him. The bottle he held in his hand tipped slightly, and a drop of sticky iron wood resin dripped onto his forehead.

In an instant, strong winds whipped up and yellow sand filled the sky.

Kurosaki Ichigo was like a whirlpool, frantically absorbing the surrounding natural energy, and even the air was distorted.

Madara Uchiha stood attentively and looked at Kurosaki Ichigo carefully, the stick supported by the iron fairy tree in his hand ready to hit him at any time.

According to the information obtained from Senju Hashirama, when too much natural energy is absorbed, different abnormalities will occur depending on the cultivator's sage mode.

The abnormality of cultivating the Immortal Mode through Iron Immortal Wood Resin is that the cultivator will turn into a plant uncontrollably and eventually turn into a big tree.

Therefore, Uchiha Madara's first concern was Kurosaki Ichigo's skin, and he was prepared to stop it as soon as any abnormality appeared.

But to his surprise, Kurosaki Ichigo's training went surprisingly smoothly.

The influx of large amounts of natural energy not only did not cause Ichigo Kurosaki to become alienated, but instead continued to increase the amount of chakra in his body.

"Is this a natural immortal body? It's really scary." Uchiha Madara recalled the legendary immortal body and couldn't help but sigh.

Just as he was sighing, Kurosaki Ichigo's consciousness had entered the ethereal realm again.

Only this time, the azure blue waterfall falling from the sky was much more ferocious than before, as if the galaxy was really flowing backwards.

The originally black and white ocean now has a blue streak in the middle.

If the light is to absorb natural energy, then Kurosaki Ichigo has succeeded.

But he knows very well that the so-called natural energy is spirit son. He is very familiar with the absorption and use of spirit son, so his current success is nothing at all.

After achieving this step, Kurosaki Ichigo was ready to work hard and practice the sage mode directly in one go.

Under his conscious control, the ocean occupied by black, white and blue suddenly surged.

The originally calm sea surface was now like boiling water, with huge waves rolling almost as high as the sky.

The flowing seawater also breaks the boundaries and balance between black, white and blue, and the azure blue, which represents vitality and nature, merges with black and white.

The black half was not bad, the black and blue slowly merged, and the waves gradually calmed down.

But the white half looked extremely violent, adding a bit of bravery to the already surging sea surface, and countless water columns bursting into the sky.

Kurosaki Ichigo was keenly aware of the resistance from the white half, and instinctively felt something was wrong in his heart.

So he immediately controlled the blue natural energy not to merge with the white part, but now it was too late.

Kurosaki Ichigo was surprised to find that the azure energy that was still under his control had lost control at this moment and fell from the deepest part of the sky with overwhelming force.

At the same time, more water columns burst out of the white ocean, rushing towards the distant sky not to be outdone.

Murderous intent, anger, pain, fear

All kinds of negative emotions came from the white ocean in large quantities, and spread out very corrosively, and were instantly transmitted into Kurosaki Ichigo's consciousness.

"what"

Kurosaki Ichigo screamed in pain, and then immediately noticed the power contained in it: "This...this is"

But before he could finish speaking, he felt his ankle being grabbed by an irresistible hand.

Then the hand exerted force suddenly, and Kurosaki Ichigo had no ability to resist, and his whole body was pulled and sank into the deepest part of the ocean.

At the last moment before losing consciousness, he widened his eyes and felt that the pure white that occupied everything in front of him was so familiar.

Then Kurosaki Ichigo fell into the boundless darkness and allowed himself to be engulfed by the white ocean.

Just after realizing all this, the originally calm black ocean also fell into a rage.

It's just that compared to the white ocean that bursts out countless water columns tit-for-tat against the blue waterfall, the black ocean has countless undercurrents.

Those undercurrents were surging, like tentacles, rushing into the territory of the white ocean, and they were still sinking.

Finally, those undercurrents reached the deepest part of the white ocean and tightly wrapped Kurosaki Ichigo, who had passed out.

The white ocean didn't seem to care about this situation, but continued to control countless water columns rushing towards the azure waterfall falling from the sky.

Terrifying power fluctuations were going on inside Kurosaki Ichigo's body, and corresponding manifestations were also shown outside his body.

Uchiha Madara frowned and looked at his adopted son who looked in pain, his face uncertain.

Because Kurosaki Ichigo didn't show any signs of alienation, it didn't seem like there was any problem, but his painful look clearly indicated that something was wrong.

Uchiha Madara hesitated for a moment, wondering if he had entered a critical period of training, and worried that his rash actions might destroy his training.

But after all, he is also a legendary figure who dominates the ninja world. Uchiha Madara quickly made a decision, his face hardened, and he was about to hit Kurosaki Ichigo with the iron fairy stick in his hand.
